The spiritual tree in the center of the courtyard is almost a change, and every morning, Tang Qing or Peng Yue, who is doing good things, carefully counts how many young shoots and how many young leaves have appeared, although this spiritual tree is not yet able to absorb spiritual energy, but the entire courtyard seems to have become vibrant.

As for Feng Ruo, he finally knew that the consequences of angering Senior Sister Lan were very serious, he was first ordered to keep vigil for a month, and then deducted thirty Five Elements Stone from the proceeds of the last hunt of the Ice Beast to reconstruct the Rushan Formation, but the worst thing was that he became the target of everyone's practice of spells, no way, to paraphrase Tang Qing's gloating words, who told him to have a pair of superlative boots that accelerated?

However, there is another thing that is very unsatisfactory, that is, the owner of this courtyard does not agree to sell, even if Lan Ling comes forward, he only reluctantly extends the lease period to ten years, it is said that it is because the old man's distant nephew is cultivating in Yuyangmen, so this courtyard has to be kept for him!

Lan Ling Tang Qing didn't have much complaint about this, after all, this spirit tree was originally planted by the other party, although it was said that it was reborn now, but they didn't spend any price.

But for Feng Ruo, he was a little annoyed, he had already made up his mind, if the lease period was up, and the other party was still willing to rent it, it would be fine, if not, hum! He sent the cold light in the Qingfeng Sword Weapon into the spirit wood again!

Of course, the premise is that Feng Ruo must put away those cold lights, after the last attempt, he found that the cold light was extremely domineering, and it was able to indulge the frost sword qi to devour himself, even if it was an attack, it was also extremely sharp, especially the distance of the attack could reach twenty zhang away! This is absolutely amazing.

However, the trouble is that every time it is released, it is necessary to consume a Five Elements Stone of the wood family, which can be described as extremely troublesome, and Feng Ruo is extremely worried that once the cold light grows up, it will form a backlash against himself, which is a great thing.

As a last resort, Feng Ruo had no choice but to ask Ye Hong under the pretext of increasing his knowledge, after all, Mingxi had forgotten a lot of things, and he didn't want to expose things about Leng Guang, and Ye Hong had lived for almost three hundred years, so he should know a lot of strange things.

"Oh, you're asking why the dead spirit tree came back to life?"

In Ye Hong's room, Feng Ruo knelt and sat in a regular manner, these times, Ye Hong taught them the basic immortal cultivation technique, and the problems in cultivation were also guided by him, otherwise, relying on Lan Ling alone would definitely not work.

"In fact, the old man has always been very puzzled about this matter, because although there are many dead spirit trees in the immortal cultivation world every year, none of them can be brought back to life!" Ye Hong sighed a little, looking out the window at the spirit tree that had grown many tender green branches, obviously this problem had been bothering him for a long time.

"So, Courtyard Master, do you know why these spirit trees die?" Feng Ruo asked quietly, he naturally knew why the spirit wood was resurrected, but he didn't know what the cold light came from!

"Well, there are many reasons for this, such as the change of the spiritual energy of heaven and earth, if the spiritual energy of a place suddenly decreases, then, even if you are diligent in watering and fertilizing, this spiritual wood will still die, but this situation is rare, and the most common reason is the natural enemy of the spiritual tree!" Ye Hong twisted a few beards on his chin and thought with his eyes.

"Natural enemies, are they those little insects?" Feng Ruo's eyes lit up and he hurriedly asked.

"Hehe, little worm, no, do you think this spirit tree is a crop planted by mortals?" Ye Hong smiled. The absorption and release of this spiritual wood is pure aura, which is of great benefit to our cultivators and all kinds of living beings, even if it is a small insect, it will not come to harm the spiritual wood, but there is a kind of existence in the legend, this thing does not belong to the dead thing, nor does it belong to the living thing, it is formless and shadowless, tasteless and traceless, but it likes to devour the wood surname Lingqi the most, especially the spirit wood, once it is entangled, this spirit wood will definitely die, this thing is the innate wood sha!"

"Congenital Mu Sha!" Feng Ruo's heart moved, and he immediately understood what that cold light was, no wonder it gave him the feeling of being violent and ferocious.

"Then is there any way to restrain this innate wood evil?"

"Hehe! restraint?" Ye Hong shook his head, "There is no way, in fact, in the immortal cultivation realm, even those high-level cultivators are helpless to take this innate wood sha, because this thing simply comes and goes without a trace, no matter how you have great ability, you can't detect the existence of this innate wood sha, how can you have a way to deal with it?"

"Therefore, under normal circumstances, in the Immortal Cultivation Sect, once a dead spirit tree is found, then it can almost be judged that there is an innate wood evil here, at this time, the best way is to quickly transplant ten or more spirit trees around this dead spirit tree, so that the innate wood evil will always stay here, even if these spirit trees are all dead, it will not leave, until it completely dies, but in this place, it must not continue to cultivate spirit trees, otherwise more innate wood will be producedDon't even try to eradicate those dead spirit trees!"

"Wow! It's so powerful, isn't this innate wood demon invincible in the world!" Feng Ruo said in surprise, he really didn't expect that the cold light to come from was so big, if it weren't for the wood spirit stone himself, it is estimated that he wouldn't even be able to find a trace of this thing.

"Hehe! The world is invincible, your kid's idea is really weird, in fact, in the eyes of this innate wood sha in the world of cultivating immortals, it can only be regarded as a difficult epidemic to prevent, as for the method of restraint, it is not nothing, as long as you find the innate golden sha, you can naturally subdue this congenital wooden sha! But the innate golden sha is only a legendary existence, no one can find it at all!"

When Ye Hong said this, he said with some doubts: "But this is also what I am puzzled about, the death of this spirit tree before must be related to the innate wood sha, but now that it has come back from the dead, can it be said that there is an existence of the innate golden sha nearby?"

Hearing Ye Hong's inference, Feng Ruozhen couldn't help but sweat profusely, this old man's imagination is also not bad! But I'm afraid it's hard for him to guess the truth.

After asking Ye Hong a little bit about the four basic formations, Feng Ruo retired and left, and now he was sure that the cold light he saw should be the innate wood sha, but it was not forced out by the innate golden sha, but attracted by his own wood spirit stone.

"Tsk, it seems that this wood spirit stone of mine is indeed a bit not simple, right?"
