As early as in the black hole under the ground of Wind and Snow City, Qin Nan and the others had seen the predecessor of the demon spirit with their own eyes, and the Heavenly Demon Mother Tree cultivated by it had its own soul, and was controlled by it, and could communicate with it, but its orders were obeyed.

This is mainly because the Heavenly Demon Mother Tree is contaminated with a large amount of its ancestral dragon essence blood, and it has been cultivated by itself, which is equivalent to its demon pet, so naturally it should listen to it.

It's just that now the ancestral dragon essence blood has been destroyed, and it has been completely refined into pure dragon blood by Qin Nan, and then it will be transformed into vitality that can be absorbed by both the primordial gods and the martial artists through Qin Nan's own heart.

Qin Nan is now planning to use his vitality to cultivate a Heavenly Demon Mother Tree of his own, because he has the capital. As for the Heavenly Demon Mother Tree he is cultivating now, it has been contaminated with the breath of Qin Nan's body for a long time, which is equivalent to Qin Nan's bloodline.

But it can't be said to be bloodline, after all, the Heavenly Demon Mother Tree is not a human being, and there is still an essential difference between humans and plants in this reckless world.

Qin Nan carried the seeds of the Heavenly Demon Mother Tree with him, let it be contaminated with the breath on his body, and was roasted from the beginning to the end. Then, Qin Nan used the vitality transformed from his heart to cultivate it and make it Qin Nan's pet.

Qin Nan's Yuan Shen stood inside the immortal lock, looking up at the tall giant tree in front of him, if nothing else, I believe that soon it will give birth to spiritual wisdom, which is equivalent to the divine soul of the Heavenly Demon Mother Tree.

Of course, Qin Nan doesn't know what the spirit of the big tree should be called, so let's call it "tree spirit" for the time being, symbolizing the soul and spiritual intelligence.

As for the role of the dryads, there are too many to count. First of all, when the dryad grows to a certain stage, its roots and branches will become extremely hard, and even the immortal gold will be cut constantly, just imagine if you use these roots and branches to fight the enemy, then it will definitely be a nightmare for the enemy.

Also, at this moment, the Heavenly Demon Mother Tree grew up under the influence of Qin Nan's blood and qi, and Qin Nan could implant part of his origin power into the Heavenly Demon Mother Tree, so in this way, it means that he is the Heavenly Demon Mother Tree, but the Heavenly Demon Mother Tree is not him.

It means that Qin Nan can manipulate the Heavenly Demon Mother Tree and let it do everything on its behalf, and as soon as Qin Nan dies, then the Heavenly Demon Mother Tree will also die. But on the contrary, the Heavenly Demon Mother Tree couldn't control Qin Nan, because she was just Qin Nan's tree spirit, and if it died, Qin Nan wouldn't die.

Even, Qin Nan can build a nest of his own in those dense professional layers of the Heavenly Demon Mother Tree, just like the ancestral dragon essence blood, lying in the nest all day long to enjoy himself, Qin Nan can store all his vitality and strength in the Heavenly Demon Mother Tree, and when the vitality is consumed, or if he has received some kind of physical damage, he can make up for it through the Heavenly Demon Mother Tree, or even directly through the Heavenly Demon Mother Tree for healing.

Because the Heavenly Demon Mother Tree itself grew up under the influence of Qin Nan's blood and qi, the vitality of the two is naturally the same. This is the benefit of cultivating the Heavenly Demon Mother Tree, of course, this is only part of it, there are many, many benefits of the Heavenly Demon Mother Tree, and there are countless of them.

"You'd better release all the dragon's blood, and don't hold any more strings, because you don't threaten me by doing so, but rather fulfill me. Release it, release it with all your might, and when you release it, you can only stay in it silently and wait for death. ”

At this time, Qin Nan took the time to say to the demon spirit in his heart, and there was a kind of show-off pleasure in his tone.

The demon spirit instantly understood that Qin Nan had already begun to cultivate the Heavenly Demon Mother Tree, so no matter how much it tossed the dragon's blood, the most it could do was to let the vitality rush out and help Qin Nan cultivate the Heavenly Demon Mother Tree.

"You...... Hmph, if you say this, then I will no longer release the vitality to you, I want to control the dragon's blood, cut off it and then send you the vitality, your Heavenly Demon Mother Tree will die sooner or later without the support of the dragon's blood, and all your hard work will be in vain, hahahaha......"

The demon spirit seemed to have found a way to torture Qin Nan again, it wanted to control the dragon blood in Qin Nan's heart, and prevent it from continuing to release its vitality.

Because the Heavenly Demon Mother Tree has a great appetite, if it is supplied with vitality for a long time, it will definitely die, just like the Heavenly Demon Mother Tree under the ground of Wind and Snow City, its ultimate result is that it will eventually wither and die because of the cut off of the source of power.

"My heart has a hematopoietic instinct, you can control the dragon's blood, but you can't completely control it, the dragon's blood will still be constantly digested, turned into vitality, and then flow to my whole body. Qin Nan said silently.

"Yes, it's true that your heart has a hematopoietic instinct and can continue to digest dragon blood, but so what? With your heart automatically digesting dragon blood, the transformed vitality is no longer enough to support the Heavenly Demon Mother Tree, isn't it?" the demon spirit said gloomily, as if he had captured Qin Nan's life.

"Hehe, what's the use of you saying that? Can you threaten me? I can find a source of energy that can replace the dragon's blood at any time, and my cultivation of the Heavenly Demon Mother Tree has nothing to do with you, do you understand?" Qin Nan said gloomily.

"You...... Good, good, good, you're doing well......"

The demon spirit was speechless for a while, at this time, it seemed that it really had no way to take Qin Nan anymore, and slowly, it fell silent and no longer fought against Qin Nan.

With the silence of the demon spirit, Qin Nannan was free, came back to his senses, and began his current situation.

The Heavenly Demon Mother Tree has grown to a certain stage, and tree spirits will be born at any time. From a distance, Qin Nan could smell the Heavenly Demon Mother Tree, exuding the same aura as himself.

Everything seems to be calm, it is finally coming to an end, Qin Nan couldn't imagine that he would cause so much trouble because of a small negligence, which means that during this time, he has been fighting with himself, fighting with himself, saying this, I am afraid that no one will believe it.

And during this period of time, he happened to miss the opportunity to reunite with the little Buddha pupil and Xiao Xun'er, just a brief meeting in the refining city, and then said a few words, and then he had to leave in a hurry.

Qin Nan smiled knowingly, it seems that if you have time, you must go back to see the little Buddha pupil, that is, Zigui, she has grown so big, and it seems that she has also cultivated martial arts, but she is not very proficient.

Qin Nan couldn't wait to meet her!

But at this time, Qin Nan's physical body encountered another trouble, and his Yuan Shen hurriedly went out of the immortal lock, and then returned to his senses.
