Ling Qingxue looked at Xia Rufei with a childlike smile, and couldn't help but smile on her face. She nodded with a smile and said, "Come on! Bring these bad guys clean up!"

Xia Rufei laughed and began to set up formations on the periphery.

This fire attack-based formation has been specially transformed by Xia Rufei, and the array materials are basically distributed on the periphery, which can be within a range of about three kilometers, and then concentrated inward attacks.

Xia Rufei chose to set up the formation more than 20 meters away from the Star Fern Thorn. After so many tests, he felt that this distance was relatively safe, which not only ensured that the formation could perform its greatest effect, but also did not attract the attack of the Star Fern Thorn when setting up the formation.

This formation was basically designed by Xia Rufei himself, but it combined with some existing array diagram principles. The originality is much higher than the trapping formation. Therefore, although it was his first time to arrange the formation, he still did not feel awkward.

Because this formation has been deduced many times in his mind and on paper.

Xia Rufei placed the formation materials around the star fern ring belt, occasionally stopping to check the position a little, and then continued to arrange it quickly.

After about twenty minutes, Xia Rufei also placed the last formation material in his hand.

He had also circled the entire star fern thorn ring and returned to the position he had just set off.

Xia Rufei directly took out ten Yuan crystals from the spiritual map space.

Then, in a hexagonal shape made of jade with mysterious array patterns outside the formation, these ten Yuan crystals were placed in.

The biggest feature of this formation is the formation control core, that is, the hexagon where the Yuan crystal was just placed, is located outside the formation.

Moreover, this formation can use both spirit stones and spirit crystals, as well as primordial crystals with higher energy levels.

Of course, the power of the formation is completely different when using different energy sources.

In order to make a quick battle, Xia Rufei directly used the most energy purity crystal, and used ten pieces at one time, putting the Yuan crystal on each position where the energy source was placed.

In this way, the maximum power of the formation can be basically squeezed out.

Of course, the consumption is also obvious.

Xia Rufei is now in the early stage of the Golden Pill, and the "Big Dao Jue" is quite energy-intensive. A single Yuan crystal can support him in practicing for a long time? It is indeed a big deal to use ten of them at once.

Xia Rufei mainly considered that he would successfully complete this task? He could also receive record-breaking rewards from the fourth floor of the Trial Tower? In addition to upgrading the Yuanzhu, there are also one thousand Yuan crystals.

In comparison, ten Yuan crystals are insignificant.

Moreover, Xia Rufei is not sure about it now? Is the fire attack effective against this star fern? So he must try it as soon as possible. Once it is not effective, he will have more time to try other solutions.

After Xia Rufei placed Yuan Jing, he protruded his mental power again? He checked the entire formation? Then he took a deep breath. He pinched a seal with his hand and penetrated it into the core of the formation.

Ling Qingxue also held her breath? Standing beside Xia Rufei, she looked at the star fern thorn ring in front of her.

One second? Two seconds, three seconds...

There was no movement in the formation, and Ling Qingxue couldn't help but show a hint of confusion.

But at this moment, a ring-shaped flame belt appeared twenty or thirty meters away from the periphery of the star fern ring belt? A stream of heat swept over, which made Ling Qingxue subconsciously hold Xia Rufei's arm tightly.

Xia Rufei looked very calm? How powerful can this formation reach? He roughly knew it in his heart.

So, Xia Rufei gently patted Ling Qingxue's tenderness and comforted her a little? As for her eyes, she was always staring at the direction of the formation.

After this ring-shaped flame belt appeared, it immediately began to extend inward. The violent combustion of the flames caused the nearby air to consume a lot, so the movement of the airflow was accelerated. Xia Rufei and Ling Qingxue both felt the wind began to blow around.

The so-called fire borrows the wind, not to mention that this is the flame controlled by the formation, so naturally the less it is, the more powerful it is.

The ring-shaped flame belt quickly penetrated inward, and in a few breaths, it had already entered the attack range of the star fern thorns, which was less than twenty meters away from the star fern thorns.

In fact, when the formation was activated and the flames appeared, the star fern thorn ring began to appear restless. The star fern thorns that looked very similar to camel thorns began to swing without wind, and seemed quite uneasy.

The flames of this formation are naturally different from ordinary world flames. In fact, this inspiration comes from the trapping formation. The flames formed by the black sharp light are almost pure white. The temperature is so high that even the most difficult ore to melt in the secular world may not last long.

Today, the flames produced by this flame array and the black and sharp flames of the trapped killing array can be said to be of the same origin. The star fern thorns obviously felt the danger and began to shrink and prepare for attack.

During several tests, Xia Rufei was only close to ten meters before the star fern thorns launched an attack. However, as soon as the formation flame entered the range of twenty meters, the star fern thorns burst out with a large number of thorns.

The ring-shaped star fern thorn bushes with a radius of one kilometer burst out a large number of thorns, as if a black shock wave extends from the inside to the outside, and the scene is spectacular.

Xia Rufei and Ling Qingxue both stood outside the safe distance, so they remained motionless, standing there watching the drama.

Of course, Xia Rufei was also constantly pinching out seals, carefully controlling the formation, and also paying close attention to the operation of the formation and the energy consumption.

In this case of squeezing the power of the formation to the extreme, the consumption is quite large. The energy in the ten Yuan crystals is rapidly passing, which is several times faster than Xia Rufei's usual consumption during practice.

Xia Rufei was not hesitant to Yuan Jing at all and always maintained the highest intensity of the formation.

The thorns that burst out cannot do anything to the invisible and intangible flames.

Moreover, after the spines shot into the ring-shaped flame, the star fern immediately took them back, but some of the spines were unable to be successfully retracted, and they were probably burned in the ring-shaped flame.

When Xia Rufei saw this scene, his heart felt slightly relieved.

It seems that the choice is right. These star ferns still have not escaped from the nature of plants, and the flames are obviously their natural enemies.

Xia Rufei pinched the seal with his hands, and the ring-shaped flame further compressed inward.

Star ferns burst out wildly, but apart from the attack of spines, they could only dance on the spot, but they could not form an effective way to deal with flames.

Finally, the ring-shaped flame belt spread to the outermost periphery of the star fern thorn ring belt.

The outermost circle of star ferns and flames began to come into direct contact.

These star ferns danced their bodies even more crazily, and the thorns burst out completely, but they still couldn't stop the flames.

When the flames touched the outermost star fern thorns, a crackling sound came, and the vines of these star fern thorns were ignited.

With a bang, the star fern itself seemed to be the best combustion aid. After igniting, the flame was almost twice as fierce as before.

Xia Rufei was overjoyed and further activated the formation to compress inward.

Perhaps ordinary worldly flames have no harm to the star fern, but the flames generated by this flame array have become their death talisman.

The ring-shaped flames encountered no resistance in front of the star fern thorns, and they advanced inward with destruction. More and more star fern thorns were ignited, and crackling sounds were endless, and thick smoke kept coming out, so that Xia Rufei and Ling Qingxue could no longer see the internal situation, so they could only release their mental power to investigate.

For Xia Rufei, after the formation is arranged, he doesn't need to take action himself. For the Star Fern Thorn Ring, this is a complete disaster.

The ring-shaped flames lasted for about fifteen minutes, and Xia Rufei's mental power was investigated and felt the inside empty. It was obvious that the ring-shaped flames had burned to the innermost layer of the star fern thorn ring belt.

Xia Rufei immediately changed his seal technique and controlled the ring flame not to extend further inward. At the same time, it was still burning with the highest power, and carried out a complete destructive attack on the star fern ring belt that had been completely covered in the ring flame.

Ling Qingxue was already stunned by the spectacular scene in front of her. She held Xia Rufei's hand tightly, feeling a little unbelievable.

When Xia Rufei set up the formation, she saw it with her own eyes, just some simple jade, array talismans, and several array flags. The most valuable one is ten Yuan crystals, but once the formation is formed, it can burst out with such great power, which is simply terrible.

The ring-shaped flame continued to burn for ten minutes. Xia Rufei's mental power found that the star fern thorns that were completely submerged in the flame had all been burned to death, leaving no trace of life.

Xia Rufei then changed the seal technique. Suddenly, the fire of the ring-shaped flame gradually became smaller and finally completely extinguished.

The thick smoke gradually dissipated, and the situation in the fire finally appeared in front of Xia Rufei and Ling Qingxue.

The two of them looked at everything in front of them and were extremely shocked.

All the star ferns remained the same as when they were fired, but they had completely turned white, and there were many thorns on the ground that were also white.

After the flames went out, there was no trace of smoke in the entire fire, which showed how thoroughly it was burning.

Xia Rufei waved his hand and a stream of energy came out of his hand, bringing a strong wind.

Then, the star fern thorns in the fire that were still in an attacking posture turned into ashes when the strong wind blew by. The entire star fern thorn ring collapsed little by little like dominoes, extending to the distal ring.

The same directly turned into ashes were the thorns on the ground that were also burned white.

Suddenly, a white ring belt with a diameter of about one kilometer appeared on the ground.

This is really burning so much that there is not even a single residue left!

Xia Rufei waved his palm again, and the white rings in front of them immediately separated a road.

Xia Ruofei smiled and held Ling Qingxue's hand and said, "Do it! Wife, we can get the reward!"

The land burned by the super flames is still very hot. Even if Xia Rufei flew over with Ling Qingxue on his sword, he could still feel the heat waves coming from the ground.

However, Xia Rufei released a little energy and easily isolated the heat wave outside.

Without the obstruction of the star fern thorn ring belt, Xia Rufei easily took Ling Qingxue to the position of the light spot displayed in the perception mirror map.

In fact, this spot of light is in the center surrounded by the Star Fern Thorn Ring Belt. After Xia Rufei and Ling Qingxue entered the interior of the Star Fern Thorn Ring Belt, they immediately found that place.

Because it's very conspicuous.

Xia Rufei and Ling Qingxue had just entered the interior of the Star Fern Thorn Ring Belt, and four stone pillars slowly rose up in this place, and it would be difficult for them to not pay attention to it.

Xia Rufei took Ling Qingxue to jump off the Qu Shuang Feijian and walked to the front of the stone pillar about four feet high.

I saw a groove at the top of the first stone pillar, which was exactly the same size as the Chu Yuanzhu.

Obviously, this is used to upgrade the Shu Yuanzhu.

At the top of the second stone pillar is a quaint storage ring. Xia Rufei reached out to pick up the storage ring and slightly explored it with his mental power, and found that it was a ownerless storage ring.

To be precise, it should be that the owner of the storage ring had stored the thing and wiped off his mental mark.

Xia Rufei easily recognized the storage ring and then looked at it. It turned out that there were indeed a thousand Yuan crystals inside, and there was nothing else.

Xia Rufei couldn't help but be shocked. This was a bit big. Just to give the reward, he directly attached a storage ring.

You should know that in the Earth's cultivation world where resources are withered, a storage ring is very precious. Some poorer Jindan monks may not necessarily have one. As for the Qi Refining Cultivator, there are very few who can have storage rings like Ling Qingxue and Song Wei.

Xia Rufei took out all the Yuan crystals inside and transferred them into the spiritual map space. Then he wiped off his mental mark and handed the storage ring to Ling Qingxue, and said with a smile: "This is an extra gift, you can keep it!"

Ling Qingxue quickly refused: "I don't want it! I don't want it! I already have a storage ring, so it's useless to hold it! And if Vivi knows..."

"Vivi is not so stingy!" Xia Ruofei said with a smile.

"That's not OK! Vivi..." Ling Qingxue said this, her eyes suddenly lit up, and she took the storage ring from Xia Rufei's hand, and said with a smile, "I know what to do! I'll give this storage ring to Uncle Song after I go back! Hasn't he already started practicing? He can use it!"

Xia Rufei was slightly stunned, then smiled and said, "This idea is not bad! But this storage ring has been given to you. You can just do whatever you want!"

Ling Qingxue giggled and said, "I didn't expect you to be quite careful! You deliberately left the good guy for me, right?"

Xia Ruofei smiled and said, "What else can we distinguish between each other! It's the same for you to give me, right?"
Chapter completed!
