The Sun and Moon Dragon Spring escaped, and the huge underground space suddenly became dark and silent, and nothing else existed.

The Dragon Evil Emperor did not waste any of it. As soon as he opened his mouth, he swallowed all the mist that spreads into the underground space. In any case, these mists were also overflowing from the Dragon Spring of the Sun and Moon, and condensed, which was comparable to dozens of ordinary holy springs.

This time it got great benefits. The holy spring he swallowed had thousands of drops, including nearly a hundred drops of the holy spring essence, which was enough to restore it to a lot of strength and help it completely refine the son of Darkness.

In this way, it may not take long to restore its former peak strength.

A holy light flashed, and an exquisite jade ring appeared in Zhang Ruochen's hand. It was an extremely high-quality space ring, belonging to the Dan Emperor.

As one of the five overlords on True Dragon Island, Danhuang is best at treasure hunting. He must have collected a lot of treasures, so it is naturally necessary to check it out.

As his mental power swept across the space ring, Zhang Ruochen's eyes suddenly changed. As he expected, even though the Dan Emperor refined many treasures himself, there were still countless preserved ones, and there were also more than 100 million pieces, but there was no holy pill.

While turning around, Zhang Ruochen took out something from the jade ring. It was a seven-leaf grass. Each leaf was filled with strange light, and it was filled with colorful light, like a dream.

Above the seven-leaf grass, various lights meet, condense into a colorful dragon, soaring into the sky, lifelike.

"roar."

The seven-leaf grass shook and made a substantial dragon roar, which was deafening.

The Dragon Evil Emperor stared at the Seven-Leaf Grass and said in surprise: "I didn't expect that the Sun and Moon Dragon Spring really raised a dragon-transforming grass. The Dan Emperor is really lucky to be able to pick it up."

Dragon Transformation Grass is an extremely special holy medicine. For creatures with the blood of the dragon, its value is higher than that of the Yuanhui holy medicine.

Especially the various ancient relics with rich bloodlines of the dragon, such as the Demon Swallowing Dragon, the Holy Dragon of the Sky, etc., are extremely eager to get a dragon-turning grass that leaps into a divine dragon, and achieves unlimited achievements.

"This dragon-turning grass should have been picked by the Dan Emperor not long ago. It was not squandered by it, so it was quite lucky." Zhang Ruochen smiled.

I think if the Dan Emperor had not used the Sun and Moon Dragon Spring to baptize his own elixir, he might have refined the dragon-transformed grass.

After all, the predecessor of the Dan Emperor was an emperor-grade holy pill refined by the Shenlong clan, which contained dragon energy, and the dragon transformation grass would be of great benefit to it.

Looking around, Zhang Ruochen said, "Let's take care of us here first, and then leave after the injury is healed."

Before, Zhang Ruochen and the Dragon Evil Emperor were both seriously injured. They felt the breath of the Sun and Moon Dragon Spring, and did not heal the first time.

True Dragon Island is full of dangers, and it is very dangerous to not keep yourself in an excellent state.

With a wave of his hand, Zhang Ruochen took out the sundial and activated it, and the power of time covered a radius of two hundred feet.

He still has a lot of things to do, so it is naturally impossible to delay here for too long. Using the sundial to heal the wound is the best choice.

Sitting cross-legged below the sundial, Zhang Ruochen took out a small amount of the essence of the Holy Spring from the Mercury gourd and swallowed it down in one mouthful, intending to practice while healing his wounds.

In a blink of an eye, three months passed, and all the injuries of Zhang Ruochen and Dragon Evil Emperor were healed, and their cultivation level was improved.

Especially the Dragon Evil Emperor, taking this opportunity, he not only refined the holy spring he obtained, but also refined the Dark Son. Although his strength has not returned to its peak, it is not much different.

Three months under the sundial, only three hours have passed outside the outside world, and I think there will be no major changes.

Flying out of the underground space, Zhang Ruochen observed the surrounding situation and whispered: "It seems that the eruption of divine power on Zhenlong Island will soon be calmed down."

The reason for saying this is because he found that the surrounding space was becoming more stable and it would not take too long to return to its original state.

"The duration of the divine power explosion is usually not too long, from several days to several hours. This time it is obviously shorter, so there should not be too many treasures to be born." said the Dragon Evil Emperor.

Upon hearing this, Zhang Ruochen didn't care much. He suppressed the Dan Emperor and gained a lot. What he was thinking now was not to find more treasures, but to find out the key to the World Gate.

Immediately, Zhang Ruochen and Longsha Emperor set off, hoping to rush to meet Xiao Hei and others as soon as possible.

He left a spatial mark on Xiao Hei, and even with many spatial fault barriers, he could still be vaguely perceived.

The key to the world gate is important. It must be seized as soon as possible, and later changes will occur.

Because the space of True Dragon Island gradually became stable, Zhang Ruochen and Dragon Evil Emperor shuttled through the space fault, making it much easier.

Along the way, they met many people, both in the heaven and in the hell.

And Zhang Ruochen was not ruthless and killed all the people on the hell.

After a long time, Zhang Ruochen and Longsha Emperor finally successfully found Xiao Hei and others, including the Demon Sound, which had swallowed all the souls of the Nether Snake.

"Have you caught that old guy?" Zhang Ruochen asked immediately.

Xiao Hei raised his head and said, "I will definitely be sure to take action. However, this old guy is very stubborn. As long as he mentions the key to the World Gate, he will pretend to be stupid."

While speaking, Xiao Hei took out the formation, causing the short and thin old man to appear.

The moment he saw the short and thin old man, a strange color appeared in the eyes of the Dragon Evil Emperor, and he said, "You can actually catch him."

"Do you recognize him?" Zhang Ruochen asked immediately.

Dragon Evil Emperor said: "Not long ago, there was an unusual movement in Zhenlong Island. A rich original aura burst out, alarming all of our five overlords. When we arrived, we happened to see him crawling out from the ground. We all took action at that time and wanted to catch him, but in the end he escaped."

"Did he appear when the original breath blew?" Zhang Ruochen asked again.

The Dragon Evil Emperor nodded: "Well, because of this, we five overlords are interested in him and think that there may be some secret hidden in him."

Upon hearing this, Zhang Ruochen's heart suddenly moved, and many thoughts flashed quickly, and a bold guess came.

"Does it mean..."

A sharp holy light surged out of Zhang Ruochen's eyes. He carefully observed the short and thin old man and said, "The key to the world gate must be a key? Could it be a person? Or, the key turned into a human form."

Xiao Hei glared at his eyes and said, "What did you say? How is this possible?"

Ao Xinyan and others also looked surprised, staring at the short and thin old man who was blocked in the formation, not understanding why Zhang Ruochen had such a guess.

After pondering slightly, Zhang Ruochen said, "None of us knows what the key of the World Sect looks like. This old guy happened to appear when the key of the World Sect was born. He has the original aura of Kunlun Realm, and is extremely affinity with the rules of heaven and earth. He also has the ability to be elusive. He has too many specialties."

In fact, when the Qianxing Tiannv said that the short and thin old man had the original aura of Kunlun Realm, Zhang Ruochen had already developed suspicion.

"Maybe Zhang Ruochen's guess is correct. We had preconceived ideas from the beginning. We never thought that the key to the World Sect would be a person, but when it comes to the origin of Kunlun Realm, everything is possible." Xiao Hei said seriously.

Hearing this, Ao Xinyan and others couldn't help but fall into deep thought. It was not that they were unwilling to believe Zhang Ruochen and Xiaohei, but that they did not want any mistakes.

Once their guess is wrong, the real world gate key will fall into the hands of the Hell Realm, it will be a great disaster for the Kunlun Realm.

Zhang Ruochen suddenly said, "Xiao Hei, let me in."

Although he didn't know what Zhang Ruochen was going to do, Xiao Hei immediately used his means to bring him into the formation.

Seeing Zhang Ruochen appear, the short and thin old man was shocked and quickly begged for mercy and said, "Saint, please spare me your life and give me another chance."

"We are monks from Kunlun Realm. We come to Zhenlong Island to find the key to the world gate. We just don't want it to fall into the hands of the Hell Realm and the Heavenly Realm. There is no need for you to be so guarded." Zhang Ruochen said calmly.

The short and thin old man turned his eyes and said, "But I really don't know where the key to the World Gate is, I..."

Before he could finish speaking, Zhang Ruochen suddenly slapped a palm, and the majestic holy energy condensed into a terrible palm print, slapped firmly on the short and thin old man's chest.

Zhang Ruochen did not reserve any of this palm and took all his strength. Even an ordinary immortal saint might not be able to withstand it.

Before the short and thin old man could react, he was knocked out directly.

Logically speaking, the short and thin old man is just a step forward in the Holy King. If he endures such a palm, he will only end up with both body and spirit.

But the fact is that although the short and thin old man rolled on the ground in a very embarrassed manner, he did nothing.

"Saint Master, I have something to say. I can get you anything except the key to the World Gate." The short and thin old man stood up and looked at Zhang Ruochen with a vigilant look on his face.

Zhang Ruochen said lightly: "At this point, do you still want to continue to disguise? If I guess correctly, you are the key to the world gate."

As soon as these words were said, the short and thin old man was shocked. Although he tried his best to hide, his face changed slightly.

When Zhang Ruochen sensed this change, he immediately sent a message to Xiao Hei and asked him to bring the Dragon Evil Emperor in.

As soon as the Dragon Evil Emperor appeared, the short and thin old man's face immediately changed drastically, and he involuntarily took a few steps back.

Under Zhang Ruochen's instruction, the Dragon Evil Emperor swallowed the short and thin old man into his stomach.

After a moment, the Dragon Evil Emperor vomited out the short and thin old man again, and then said to Zhang Ruochen: "Master, his body is completely composed of the original power of the Kunlun Realm."

Upon hearing this, a smile suddenly appeared in Zhang Ruochen's eyes and said, "Do you have anything else to say?"

"I really shouldn't have come out to watch the fun." The thin old man sighed helplessly.

Zhang Ruochen shook his head and said, "You are wrong. This time, the Hell Realm has mobilized many troops. No matter how good you hide, they will definitely find a way to find you. Kunlun Realm will be destroyed. Only when we find it, you can be protected."

Leaving this sentence, Zhang Ruochen and Long Shahuang left the formation and no longer said anything to the short and thin old man.

Whether he wants it or not, he will force him out of True Dragon Island, causing the plan of the Hell Realm to fail.

At this moment, everyone had already believed that the short and thin old man was the key to the world, and he couldn't help but breathe a sigh of relief.

Since they have obtained the key to the World Gate, they should undoubtedly withdraw from True Dragon Island to avoid any more abnormal changes.

The awakened people showed hesitation and did not seem to want to leave so soon.

After a brief discussion, the Saint King Zi Xin came forward and said, "We plan to stay on True Dragon Island for the time being to see if we can find the Sun and Moon Dragon Spring."

"Do you really need the Sun and Moon Dragon Spring?" Zhang Ruochen asked curiously.

The Saint King Zi Xin explained: "We need the Sun and Moon Dragon Spring to baptize ourselves, and while restoring our strength, we will erase the breath that has been sleeping for a long time, so that we can walk in the Kunlun Realm."

Now the situation in Kunlun Realm is becoming more and more complicated. Naturally, they awakened people do not want to hide in the sea of ​​yin and yang, but want to play a greater role.

Hearing this, Zhang Ruochen couldn't help but smile, and took out the Mercury gourd and poured out a large holy spring from it, with a total of ten thousand drops.

Of course, these are just ordinary holy springs, not the essence of holy springs.

“Are these enough?”

For a moment, everyone's eyes were locked on the large holy spring, and time and space seemed to have fallen into static at this moment.
