The stone door was broken, the yin wind rushed out, and a hole three zhang high and about two zhang wide appeared in front of him, and a row of bluestone stairs went down along the passage, not knowing where it leads.

The yin qi inside is even stronger, blocking the divine sense, and the two of them can't see the end with their extreme eyesight, and one yin wind rushes out, making people shudder.

"It's okay!" the dragon girl smiled, raised her hand and waved a colored bead, which shot out a five-colored light, forming a curtain, and hung down to protect the two of them.

"Hehe, you can see through this!" Lin Han smiled bitterly, and said in his heart that she was worthy of being a dragon girl, and she actually had such a top-level magic weapon.

To be honest, he was really struggling in the face of the thick yin wind just now, if it weren't for his nine-trick exquisite body and strong physique, I'm afraid he would have been blown into slag a long time ago.

Ao Tingxin is a golden immortal and a dragon body, she can bear it, Lin Han is really a little difficult to resist, but with this bead, there is no big problem.

"Let's go, let's go in!"

The two leaned close together and walked into the cave.

The yin qi inside is even more chilling and piercing, and the rich dead qi is almost condensed into substance, even if there is a multicolored bead body, the thick dead qi rolls in, and there is a tendency to wear out the colored curtain.

The dragon girl was shocked when she saw this, and hurriedly sacrificed the cold light sword in the air, she played the magic trick again and again, and suddenly the cold light sword was full of light, exuding a solemn and holy brilliance, in a vain attempt to annihilate these dead qi.

Snort!

The dead air was like a flame of fire, and it was annihilated.

Ao Tingxin smiled, a little proud, and continued to walk inside with Lin Han.

But it didn't work far away, the ghost qi in the passage became more and more intense, almost forming a substantial invisible airflow, under the impact of this rich dead qi, the brilliance of the cold light sword became smaller and smaller, and if it persisted, even the cold light sword would be corroded.

Once the Cold Light Sword is corroded and loses its spirituality, it cannot be used.

Ao Tingxin hurriedly withdrew the cold light sword, and sneered! The rich death qi began to corrode the multicolored light mask again.

"What should Childe do, why don't we quit?" Ao Tingxin said in shock, she could see that even if she was a Golden Immortal cultivator, it would be difficult for her to pass through this passage.

Once the multicolored light mask is also worn out, the two of them will have to die here.

Magic weapons can't work, let alone with the strength of the flesh, once the dead qi drowns the two of them, I'm afraid that there will be two more white bones in this cave in an instant.

Such a strong dead qi is almost something that non-human beings can resist, so Ao Tingxin is a little panicked.

"Princess, don't worry, I'll try!" Lin Han said, he moved his mind and sacrificed the little sapling, and the seemingly strong ghost aura couldn't help the little sapling.

The little sapling took root in the void and shook it gently, and suddenly almost formed a substantial dead qi and turned into the nutrition of the little sapling, decreasing at a speed visible to the naked eye, in stark contrast to the situation just now when Ao Tingxin urged the cold light sword to kill the dead qi and almost did not decrease.

"That's right!" Lin Han was secretly happy in his heart, he had doubted that the little sapling could absorb the purest energy, but now it seemed that it was indeed the case.

To put it bluntly, these dead qi are also condensed by the soul power of the dead monks, and they are a manifestation of energy.

Last time in the ancient battlefield hall, the little sapling sucked the remnant soul of the powerful god clan, Lin Han sacrificed the little sapling for a try, but he didn't expect it to be successful.

"World Tree, is this really the World Tree?" Ao Tingxin was stunned again, looking at Lin Han's angular face, he couldn't help but look at it for a while.

Last time Sun Wukong crusaded against Heavenly Court, she also followed, she originally thought that the Jade Emperor was slandering Sun Monkey and Lin Han, but now it seems that the Jade Emperor really did not wronged them, otherwise where would he get the sapling.

To put it bluntly, it is a synthesis of yin and yang, and mana rotates between the two to achieve the purpose of harmonizing yin and yang and understanding each other, so that double cultivation can improve cultivation.

In this way, both sides have no secrets in each other's eyes, of course she saw the little sapling in Lin Han's sea of knowledge, it was just a suspicion, but now she is sure that this is really the sapling of the World Tree, otherwise how could it be so powerful.

"Huh?" The dragon girl suddenly saw the white fruit on the little sapling again, and was stunned again.

Lin Han didn't care what she thought, and continued to control the little sapling to absorb the soul death qi here.

The little sapling completely absorbs these dead qi as nutrients, and like the tide receding, the dead qi of the entire cave is decreasing at a rate that is visible to the naked eye.

With the little sapling, compared to the embarrassment just now, the two of them became idle, and they couldn't even use the colorful beads on the dragon girl's head.

"Childe, you really have the World Tree!" The dragon girl looked at Lin Han's beautiful eyes.

"It's really the World Tree!" Lin Han smiled bitterly, he had never dared to believe that what he had cultivated was the World Tree, and now Ao Tingxin confirmed again that he also felt that he was cultivating the sapling of the World Tree.

"I hope the princess will not tell me about it. Lin Han said with a smile.

"That's nature, it's your woman!" The dragon girl blushed and said with a smile, even if Lin Han was just a god realm at this moment, she felt extremely proud that she had such a man. How can something like the World Tree be casually owned?

Suddenly, she pointed to the fruit on the branch of the little sapling and said, "Childe, where did you get this thing?"

"Oh, this, I was just about to ask you what this is!" Lin Han smiled.

It turned out that he wanted to ask the monkey, but Sun Wukong has been in retreat, and Ao Tingxin wants to talk about the actual age is much older than Sun Wukong, and he should have more knowledge, so he must know.

"Childe, tell me how this fruit is obtained?" Ao Tingxin said with a smile.

Lin Han told the story of killing the god puppet with a small sapling in the ancient battlefield hall and achieving this fruit, and then asked, "How is the princess, do you know what this thing is?"

"If I'm not mistaken, this should be a true immortal fruit!"

"What?True Immortal Fruit?" Lin Han looked stunned, it seemed unusual to hear this name.

Ao Tingxin nodded and said: "I just heard about it, I haven't seen it in person, it is rumored that the World Tree is the nemesis of the Protoss, every time this tree kills a Protoss monk, it will absorb all its essence and produce a fruit, which is cyan, gray, white, light gold, and gold, the darker the color, the higher the level of this fruit, and this fruit is white, so this fruit should be a true immortal fruit!"

"What's the use of the True Immortal Fruit?" Lin Han couldn't help but ask.

Ao Tingxin smiled, "Since it is a true immortal fruit, if a Heavenly Immortal Monk takes it, he can become a True Immortal, even if a high-level immortal takes it, it is also beneficial, if the Heavenly Immortal is below, the cultivation can grow by leaps and bounds, maybe you can achieve a Heavenly Immortal!"

"I'll go, so powerful?" Lin Han was also dumbfounded, he didn't expect such a magical thing, and he couldn't help but be excited when he thought that he had a true immortal fruit.
