The fourth fire domain is a black flame, but this fire still cannot do anything to Zhou Tong.

keep going.

Soon the fifth fire domain arrived, and here was a golden flame. Even Zhou Tong felt a hint of dry mouth and tongue, and the flame here could already affect him.

"But it's still not enough. The flame here is too weak. I'm afraid that even if the Eternal Blue Gold burns here for a year or two, it will be difficult to melt!" Zhou Tong sighed softly.

There are nine kinds of immortal gold in this world, each of which has its own unique abilities. For example, once the Phoenix Blood Red Gold is sacrificed to the extreme and the secret of immortal gold is developed, it can be reborn like a phoenix; for example, if the Divine Scar purple gold is sacrificed to the extreme, it can copy the great road patterns between heaven and earth.

Similarly, Eternal Blue Gold also has such a mystery of immortal gold.

The mystery of the immortal gold of eternal blue gold lies in the word "eternity".

In layman's terms, eternal blue gold is the hardest one among all immortal golds, and this kind of immortal gold is also the most difficult to process among all immortal golds. Of course, this kind of immortal gold is also the most difficult to destroy and corrupt among all immortal golds.

You should know that even if the immortal gold is staying in a place with insufficient spiritual energy, the immortal gold will rust and rot after tens of millions of years, and its spirituality will be lost, but there is only the exception of eternal blue gold.

Once the eternal blue gold is sacrificed to the extreme, it has developed the unique mystery of immortal gold. It is strong and immortal, and even in an exhausted place, it can last forever!

This is the true mystery of eternal blue gold, and it is also the true meaning of the word "eternal".

"Continue to move forward, the flames coming from the sixth level of purple qi should barely be able to refine eternal blue gold!" Zhou Tong continued to move forward, and soon passed through the area of ​​the fifth level of golden flame and arrived at the sixth level.

The sixth fire domain is called purple Qi coming from the east. The flames here are not like fiery fire, but like purple mist flowing, hazy.

The sixth floor of the Fire Domain is a place where powerful weapons are refined. It is very quiet in normal times. There is no sound here, except for the stone forest that is intertwined with canine teeth, there is no other scenery.

Entering this heavy fire domain, Zhou Tong's face suddenly became much more serious.

But he was not overly nervous, after all, this heavy fire domain could not do anything to him.

"This heavy fire domain is worthy of being a place for powerful weapons refining. This kind of flame... is amazing!" Zhou Tong looked at the flames around him carefully, then nodded.

He grabbed it casually and sent a ray of purple mist into his sea of ​​wheels.

"boom!"

Suddenly, Zhou Tong's purple sea of ​​bitterness swept up endless waves, blocking the purple fire and covering it inside.

Then, the purple flame was swept by the purple sea water, and was immediately submerged and about to be extinguished.

"As sure as I expected, as the Cangtian Badao Body, who is the same level as the Ancient Saint Body, I naturally don't fear these purple fires!" Zhou Tong nodded, and then came to the hottest place in the "Purple Qi Comes East" fire domain.

The fog was rich, like a liquid that could not be dissolved. There were some human-shaped ashes on the ground. Obviously, some big men died here to refine weapons.

"Buzz!!"

Zhou Tong thought about it and his Ten Cave Heavenly Divine Ring appeared instantly.

The moment this divine ring appeared, there was a blank space around him, and the purple mist seemed to be afraid and dared not approach. There was no purple fire in the area around Zhou Tong.

In just a moment, Zhou Tong felt the temperature around him drop sharply.

"Are you afraid of my Ten Cave Heavenly Divine Ring?" Zhou Tong was stunned, but then he understood.

Because these ten cave heavens are connected into a divine ring, they are essentially at the same level as the only cave heaven of Emperor Huangtian, and at the same level as Zhou Tong’s own wheel sea.

Since the purple fire was easily wiped out by the "water" of the Wheel Sea, it naturally could not do anything to the Ten Cave Heavenly Divine Ring.

Moreover, there are two treasures, the White Tiger Magic Medicine and Bodhizi, in his Ten Cave Heavenly Divine Ring. Naturally, this purple fire is even more difficult to get closer.

"You can start refining weapons!" Zhou Tong quickly turned on the most primitive function of the Ten Cave Heavenly Divine Ring.

"call!!"

Suddenly, a breeze seemed to blow from the sixth floor of the fire domain, sweeping the purple mist around it, and drilling towards the Ten Cave Heavenly Divine Ring together.

The essence of the Ten Cave Heavenly Divine Ring is actually the Cave Heaven.

The function of the cave heaven is to absorb the essence of heaven and earth from the outside world and then refine it into the vitality of the monks themselves.

Now that I am in the Fire Realm, the essence of the outside world is naturally the flame from the purple qi.

Soon, the fist-sized eternal blue gold in the Ten Caves Divine Ring was completely tolerated by the purple fire. At the same time, Zhou Tong also burst out with the power of his Ten Caves Divine Ring, completely suppressing the purple fire and preventing it from leaking.

The purple flames burned in the Ten Cave Heavenly Divine Ring, constantly tempering the eternal blue gold, and the clanging sound was endless.

One day, two days, three days...

Time passed day by day, and half a month later, even the purple mist in this area became much thinner, but the eternal blue gold still only slightly deformed and did not move towards the direction that Zhou Tong thought in his mind.

"No... the flame here is still too weak." Zhou Tong pondered for a while, then shook his head, "It may take ten years to train the eternal blue gold here."

He stood up and continued to penetrate deeper into the fire domain.

Soon, he arrived at the junction of the sixth and seventh floors of the fire domain.

The five-colored clouds and mist in front are hazy, not like flames at all. They look like fairy spirit. They look extremely peaceful, but they are shocking.

But Zhou Tong was not afraid at all and still walked forward calmly.

As soon as he entered the seventh level of fire domain, Zhou Tong suddenly felt the heat rising again. Even with the suppression of the Ten Cave Heavenly Divine Ring, he felt extremely hot.

"This fire domain can still withstand it! Let's try it first and see if these five-color flames can make the eternal blue gold form!" Zhou Tong walked directly to the hottest place in the seventh fire domain and sat down cross-legged.

The five-colored divine flame instantly entered the Ten Cave Divine Ring. The eternal blue gold was quickly wrapped in the five-colored flames and was constantly tempered.

For a moment, a clanging sound like a ironclad sound came out of his Ten Cave Divine Ring. Zhou Tong had already thought of the style of the Vajra carving in his heart, and was constantly tempering with the divine fire here.

"Sure enough, the flames on the seventh level are much more terrible. One day, it can be worth half a month of hard work on the sixth level!" Zhou Tong looked at his eternal blue gold slowly deforming, nodded slightly, but soon shook his head again.

"But it's still too slow... At this speed, it will take at least half a year to complete it! I don't have that much time to spend here!"

"And this is still an eternal blue gold that is as big as a palm. If it were my divine mark purple gold, it would be even more difficult to refine." Zhou Tong was silent for a while, then stood up again and continued to walk deep into the fire domain.
