From the ruby inheritance, Chen Nan knew that cultivators had reincarnation, and if he inherited this exercise, once he failed, he would not even have the opportunity to reincarnate, and the real Wandai would be extinguished.

This is obviously a chaotic exercise, and it is recorded in the red jade that the chaotic exercise is the supreme cultivation exercise, but Yantian is against the heavens, and will be punished by the Heavenly Dao.

"To accept or not to accept?" Since it is a chaotic exercise, Chen Nan chose to accept it without any hesitation, what if he does not enter reincarnation?

As soon as Fang chose to accept it, all the information about this exercise poured into his mind, and the Yantian Holy Technique brought him an unprecedented shock, as long as there are traces to follow, it can be deduced, exercises, formations, and Dan Dao can all be deduced with existing things, and new exercises and Dan Dao can be derived.

But he soon discovered a problem, this is just a practice before the Dragon Transformation Realm, and the next realm of Qi Condensation is the Dragon Transformation Realm, which means that once he reaches the Dragon Transformation Realm, this exercise is not applicable.

But how can you practice without a follow-up exercise? Can the "Yantian Sacred Technique" deduce itself? Chen Nan couldn't figure it out, but this is a chaos exercise after all, let's use this exercise to cultivate first, since it is its own world, it will never harm itself.

Chen Nan firmly inherited this exercise, and when he looked back, the stone tablet had disappeared at some point, and he must have integrated into the small world.

Chen Nan immediately sat down cross-legged and tried to use the "Yantian Sacred Technique" to run the exercises, there was nothing wrong with it, but the line and speed of the true qi were very different from before.

In any case, he has a small chaotic world, and Hongyu records that the small chaotic world does not have those powers, so the fact that he has a small world must not leak out.

Looking at the space around him, he quickly realized a problem, he was only happy just now, how can he get out now? Chen Nan thought about the scene when he came in, but he entered it by himself, so his mind moved, and sure enough, he appeared in front of the small tree again.

The small green and crystal tree showed signs of withering because of the loss of the Dragon Ball. Everything arranged here is for this small sapling, and Chen Nan knows that this small tree is not simple, and it should be difficult to survive if planted in an ordinary place.

Suddenly, he thought of his own small world, and wondered if he could do it if he could do it if he was planted in a small world.

The duck egg was left in it just now, and at this time it was lying on the ground crying, thinking that Chennan didn't want it, and the grievance that cried.

"Haha, there is finally a place to put this little thing, and in the future, let this foodie live in a small world. ”

"Whoosh!" the duck egg flew to his shoulder, grabbing his hair and refusing to let go, for fear that he would abandon himself again.

Chen Nan ignored it, and carried a small tree more than half a meter high to the stream to plant him. But as soon as he put the sapling on the ground, the little tree seemed to have life, and the rhizome went straight into the soil, and he didn't need to care about it at all, but it took root and grew on its own, and soon became vigorous again.

Chennan is happy, it seems that this place is very suitable for the growth of this sapling, and he doesn't have to worry about it anymore, as for what is the use of this tree, he can study it slowly.

"Whoosh!" Seeing that the sapling had regained its vitality, the duck eggs flew down and lay down under the tree, as if unwilling to go.

"Okay, then you can live in it from now on!" said Chennan.

Strangely, this time the little thing did not show dissatisfaction, and squinted under the tree, as if enjoying it, and was about to sleep.

Chen Nan remembered that the silk had not yet been put away, and just wanted to go out and stopped, squatting in front of the duck egg and looking at it, and said in a very serious tone: "I warn you, you are not allowed to eat this tree!"

Duck Egg pursed his lips, too lazy to pay attention to him, looking like you have long hair and short knowledge. Through the expression of the duck egg, Chen Nan realized that this tree was not an ordinary thing, otherwise he would not have made the duck egg so honest.

Chen Nan came outside, thinking about how to collect the silk. The Celestial Silk shone with a colorful light, and it was not dimmed by the absence of the Dragon Balls.

Chen Nan took out a few swords and tried it, the heavenly silk was extremely tough, it couldn't be cut at all, not even the ice soul, so he had to find a way to pull the heavenly silk out of the trunk, fortunately, the trunk didn't know how many years it had withered, and it was absorbed by the sapling, and it had been loosened, and finally he pulled it out of it one by one and put it into the space.

After collecting the silk, there were no other treasures in it, but Chen Nan still didn't leave, took out the ice soul, and tried his best to cut two sections of the trunk and put it into the Qinglian World.

Although this big tree has withered for I don't know how many years, it is still extremely strong, the hardness is comparable to gold and iron, it is definitely a priceless treasure, and it can also be used for refining, even if it is sold as wood, it can be sold for a sky-high price, so he kept two sections for later use.

After doing all this, Chen Nan let out a sigh of relief, and finally knew the purpose of this seed, it was actually a small world, and he didn't have to worry about what kind of freak he was.

Chen Nan looked up at the hollow trunk, and looked down again, there was no bottom below, he didn't know how deep it was, such a tall tree, it could be said that it was unique in the world, he suddenly remembered the building tree recorded in the red jade, this tree would not be the legendary building tree that was destroyed by ancient powers, right?

With this thought, Chen Nan took the Jiuyang Wood Needle out of the space, and the breath of the two turned out to be exactly the same, the red jade recorded that the Jiuyang Wood Needle was refined from the heart of Jianmu by ancient power, and at this time Chen Nan can roughly determine that this giant tree should be the legendary Jianmu, also known as the Tongtian Holy Tree. As for the legend that the building tree reaches the heavenly realm and runs through the nine shadows, it may be mythologized, or something happened in ancient times that caused the holy tree of Tongtian to be moved to Mount Everest.

"What is that little sapling? It can't be Jianmu, right?" But soon Chen Nan shook his head again, this sapling is too small, when will it grow into such a big tree? But if not, how can the two have the same breath?

Some things can't be understood without that realm, so Chen Nan no longer bothered about this issue. He went up the trunk of the tree to the mouth of the cave, came out of it, and remained a little reluctantly for a moment, then climbed to the top and cut off a few branches to collect the space, and then returned to the cave.

After finding some stones to seal the entrance of the cave, Chen Nan refined several more array flags, ate a barbecue, and only came to the outside of the cave after refining, considering that this may be a building wood, it is better not to leak it out easily.
