Next to this Heavenly Soul Sacred Tree, there are countless blue lights flashing, all of which are wood demons.

In addition, there are a large number of exotic creatures such as butterflies, bloodthirsty mosquitoes, bees, etc.

At this time, Zhao Feng understood why the Wood Demon King could drive those giant bloodthirsty mosquitoes, because these creatures all had to survive on this Heavenly Soul Sacred Tree, and the reason why this Heavenly Soul Sacred Tree could live for a thousand years was because of these Wood Demons.

No, it should be said that they coexist with each other, if the Heavenly Soul Sacred Tree withers, the Wood Demon will also have to die completely.

"Okay, I'll help you save a Heavenly Soul Sacred Tree. ”

Zhao Feng didn't say a word, he directly took out some blood bottles, and then smashed them directly into the Heavenly Soul Sacred Tree.

"Click!"

The blood vial shattered, and Zhao Feng's blood full of vitality floated on the Heavenly Soul Sacred Tree, and it was immediately absorbed into it.

I don't know if the vitality in Zhao Feng's blood is too strong, or because this Heavenly Soul Sacred Tree is already dying, after the blood of these more than ten blood bottles is absorbed by it, those positions are glowing with blue light and begin to spread rapidly.

"It doesn't seem like that's ...... enough"

Zhao Feng glanced up, this Heavenly Soul Sacred Tree was at least more than three thousand meters high, and if he wanted to save it, he was probably going to bleed again today.

Since Xiaolong took a large number of blood vials last time, he simply cut his hands open and began to spill blood.

The breath of life of this Heavenly Soul Sacred Tree also began to grow gradually and regain its vitality.

Seeing this, the surrounding creatures also boiled.

For a whole hour, it took Zhao Feng a full hour to save this Heavenly Soul Sacred Tree.

At this moment, this Heavenly Soul Sacred Tree had recovered from its withered state to its near peak, and at the same time, a large amount of Zhao Feng's blood was stored in the trunk, and it was estimated that it would surpass the peak after a while.

The surrounding group of wood demons and alien beasts began to celebrate, they had been here with the Heavenly Soul Sacred Tree for thousands of years, and now that they had been rescued, they were naturally happy to death.

"Okay, I've revived it, isn't it time for you to make good on your promise?"

Zhao Feng looked at the Wood Demon King and said.

The latter looked at Zhao Feng gratefully, and then led the way ahead, and after making a big circle, Zhao Feng saw a tree hole in the air at a height of thousands of meters.

Just now, he was spilling blood around the Heavenly Soul Sacred Tree, but he didn't see this tree hole, and now, there was an extra tree hole.

In this tree hole, there is a cyan Gongfa Dan, the size of a fist, which is emitting blue light.

The Holy Seed of the Heavenly Soul Sacred Tree!

Before, with his insight into the soul eye, he could see that the Heavenly Soul Sacred Tree was about to die, and he would live for a few months at most, but just now, he didn't see this tree hole, nor did he see any Gongfa Dan.

"Good guy, you're writing me a blank check!"

Zhao Feng immediately reacted.

This Wood Demon King really made a good calculation, first let him save the Heavenly Soul Sacred Tree, and then let the Heavenly Soul Sacred Tree condense a holy tree seed.

If he couldn't save the Heavenly Soul Sacred Tree, then the Heavenly Soul Sacred Tree wouldn't have the ability to condense the Holy Tree Seed even if he wanted to.

Although he was a little unhappy, Zhao Feng didn't bother to care about it so much, so he directly swept over and took this holy tree seed.

The Wanmu Sect used to rely on this Heavenly Soul Sacred Tree to survive, but at that time they were in a hurry to leave, after all, one step later might lead to annihilation, and they already had a holy tree species, so they let this Heavenly Soul Sacred Tree go untouched.

Now that Zhao Feng has saved this Heavenly Soul Sacred Tree, he has also taken the Holy Tree Seed as a reward, and the transaction is considered complete.

However, when Zhao Feng received the holy tree seed into the system space.

"Ding! Congratulations on opening the hidden system and cultivating the system!"

"Ding, are you planting sacred trees?"

Suddenly, two system prompts made Zhao Feng tremble.

"What's the situation, the hidden system?"

Zhao Feng was shocked.

He remembered that there was only one system that he hadn't opened up yet, and that was the battle body fusion system, but now, there was a hidden cultivation system.

It's really not that simple!

"Cultivation system, what's the use?"

Zhao Feng was not in a hurry to answer, and first sank his mind into this cultivation system.

This cultivation system is actually a cultivation space, and there is a grassland in it, and the size of this cultivation space will increase with the ascension of Zhao Feng's realm.

Next, Zhao Feng can plant the Heavenly Treasures in this cultivation space, cultivate them, and when the Heavenly Treasures are ripe, he can pick them.

To put it simply, he will be equivalent to a mobile treasure land in the future, and a large number of heavenly and earthly treasures will be born and then picked by him.

These heavenly treasures can be exchanged for alchemy, alchemy and so on.

That's not the main thing, though.

What caught Zhao Feng's attention was that living creatures could be received by him in the cultivation space, for example, Fei Fei would no longer need to stay in the war beast space in the future.

"Haha, okay, in the future, I will build the cultivation space into a cultivation treasure land, and I have more abundant heaven and earth aura than the outside world, and in the future, Fei Fei can directly cultivate in it. ”

Zhao Feng's expression rippled.

It's just that the living creatures in this cultivation space have requirements, and humans can't enter them, but the stone demons and wood demons can.

Zhao Feng didn't think about it so much for the time being, and replied directly in his mind.

"Yes!"

Then, he was the Sacred Tree that began to plant the Heavenly Soul Sacred Tree, in the center of the cultivation space.

Immediately after the sacred tree was planted, only a small sapling grew.

Subsequently, Zhao Feng called the blood vial again, using his own blood as a water source, and watered it for a few seconds.

The sapling received blood rich in vitality and began to grow rapidly, and in the blink of an eye, it grew into a large tree in the sky, dozens of meters high.

At the same time, after this little Heavenly Soul Sacred Tree grew up, Zhao Feng also felt that the heaven and earth aura in the cultivation space had undergone earth-shaking changes.

"It's really amazing, now the heaven and earth aura in the cultivation space has surpassed the spiritual spring in Haijiazhuang!"

Zhao Feng was shocked.

At that moment, he just continued to water the blood, and the Heavenly Soul Sacred Tree continued to grow, and soon it was a hundred meters high, and the concentration of heaven and earth spiritual energy greatly exceeded the spiritual spring in Haijiazhuang.

"I have an immortal battle body in my body, and I will continue to water this Heavenly Soul Sacred Tree with blood in the future, so will it grow into an immortal?"

Zhao Feng suddenly had such an idea.

However, the things that are rich in vitality are not only his blood, but also the immortal fountain that he exchanged from the crystal fairy, and it is also the best immortal fountain.

However, judging from the behavior of the crystal fairy who used the Immortal Divine Spring to ask for it that day, even the best immortal divine spring was not comparable to his blood.

Zhao Feng tried it with the Immortal Divine Spring, and sure enough, the effect was much worse than his blood.

Although the Immortal Fountain is the best, its main effect is to prolong life, otherwise how could the Crystal Fairy exchange his blood for the Ultimate Immortal Fountain?
