After establishing the next enchantment, Lin Fan did not stop there. The harm of black gas was too great, and Lin Fan didn't dare to take it lightly at all, so he decided that it would be better to add a layer of insurance outside.

Lin Fan thought about it for a while, it was better to use the surrounding forest as a base and set up a large array outside the enchantment, which could not only protect the enchantment, but also serve as a second line of defense to block the black qi, completely cutting off the hope of the black qi leaking out.

However, ordinary mortal trees will definitely not be able to make the eyes of the formation, after all, the strangeness of the black gas has been seen by all just now, and a big tree has been sucked dry by the black gas in a blink of an eye and turned into dead wood.

Although the black qi is diluted many times now, ordinary trees still can't resist the encroachment of the black qi, so Lin Fan has to strengthen these trees first, the stronger the big tree as the eye of the formation, the more powerful the formation will naturally be.

Lin Fan drew a large amount of spiritual energy from all over the plane and gathered it here, forming a violent spiritual energy tide nearby.

Under Lin Fan's control, the aura that was pouring here from all directions was infused into the trees outside the barrier. Under the watering of a large amount of spiritual energy, these already leafy trees grew rapidly, rising at a speed visible to the naked eye.

This was originally an inaccessible place, and in this large primeval forest, there were some towering trees, and under the catalysis of the aura, they directly soared to a height of more than dozens of meters.

Catalyzed by the aura, these big trees have not only increased in size, but the aura in their bodies has also increased dramatically, and a faint consciousness has been born in the big trees, and these ordinary big trees have been transforming into more advanced forms.

In layman's terms, these trees are about to become spirits, and under the influence of aura, it is not only animals that can cultivate into goblins, but also plants.

Especially the dryad, although it is inconvenient, it has an innate advantage in size, and the background is even more amazing. Once the tree cultivates into a demon, its strength will far surpass that of ordinary demon beasts or human cultivators.

The aura storm formed by the aura mobilized by Lin Fan lasted for half a day, and under the watering of so much aura, all the big trees within a kilometer outside the enchantment skyrocketed, forming a clear gap with other trees.

And the changes on these big trees are not only these, I saw a shaking on the ground, and these giant trees also shook violently.

Then I saw a big tree move, and the roots of the big tree were pulled out of the ground, and then it stood up from the ground.

At this time, the tree looked like a human, its dense roots were entangled to form two legs, and the branches that extended into the air were its hands.

The first tree rose from the earth, and the other trees rose from the earth, and in a short time countless tree men appeared in the forest.

"With the power of these tree people, even if something unexpected happens, it should be enough to deal with it!" Lin Fan said with apprehension in his heart.

With so many treants, it is already the most powerful force in the entire world, and even the dominant race humans in this world cannot match these treants.

Lin Fan did this, not only to use these tree people to block the black qi that might spread, but also to deal with possible emergencies.

No matter what, having such a force guarding here can also make Lin Fan feel a lot more at ease. In case someone who died came here and touched the barrier set up by Lin Fan, these tree people could also send them away.

However, although these tree people possessed great strength, they did not have too high intelligence, and Lin Fan only used his aura to endow them with a powerful body.

It is not so simple to open the spiritual intelligence, and the demon beasts still have to cultivate for countless years to open the spiritual intelligence, not to mention the plants, the difficulty of plants to open spiritual wisdom is much higher than that of animals.

However, the lack of spiritual intelligence of these tree people is also a problem, Lin Fan thought about it and decided to choose a tree man to open the spiritual intelligence for it, and then let it be the leader of these tree people, responsible for guarding the enchantment.

As he spoke, a little white light floated out of Lin Fan's hand, and then landed on the tree man who climbed out of the ground first, and the spiritual light entered the tree man's body, and then a dazzling light bloomed from its body.

This spiritual light is that Lin Fan used a trace of the origin power of heaven and earth, although it is only an extremely small bit, this is the origin power of this world after all, but the energy contained in it is extremely huge.

Just such a little bit of Heaven and Earth Origin is enough to open the spiritual wisdom of a tree man, and it is more than enough, and the body of that tree man quickly became larger, and in the blink of an eye, it became as much as double in size, and among these burly tree people, it was as conspicuous as standing out from the crowd.

On the trunk of the tree man, the appearance of a human face slowly emerged, and the tree man slowly opened his eyes, revealing a bit of spirituality and wisdom in his eyes.

"In the future, you will be the leader of the Treants, and the duty of the Treants is to guard the barrier for generations, not to leave the forest without permission, and at the same time prohibit anything from coming out of the barrier, and once an abnormality is discovered, it must be stopped at all costs. Lin Fan's voice came directly into the treeman's mind.

"Yes!" a dull voice came from the tree's mouth, the voice was so loud that it matched the treeman's massive body.

Then Lin Fan began to arrange the enchantment, and when Lin Fan waved his hand, the power of heaven and earth flowed with it, and spatial fluctuations appeared, forming a formation outside the enchantment again.

An invisible force came from the ground and entered all the treemen, connecting the power of all the treemen with the earth, and the power of the two blended together, and then each of the treemen echoed each other, weaving into a large net, covering this area from the sky to the underground.

"By the way, let's tell the Tianshan Mansion Monarch again, let it pay attention to here, it is best to cultivate a mountain god to be stationed here. Lin Fan thought of the Tianshan Mansion Monarch, it was better to let him send a mountain god over, and he could also add another layer of protection, and he couldn't be too cautious about the black qi.

As for where did this mountain god come from? Of course, the Tianshan Mansion Monarch had to cultivate it himself, and it was far less troublesome to give birth to an ordinary mountain god than to give birth to a god of the level of the Tianshan Mansion Monarch, and it would be enough to use the Tianshan Mansion Monarch's own strength, so Lin Fan would not interfere.

With these insurances, Lin Fan was also a lot more relieved, originally he wanted to personally enter the black qi to investigate the situation inside, but when he thought of the terrifying power of the black qi, he still dispelled this idea.

Lin Fan's consciousness can't go in, so he can only use his physical body to enter, but Lin Fan's mortal body is only the strength of the Jindan stage, and after entering, he will definitely not be able to withstand the corrosion of the black qi, and if he can't do it, he will explain it inside.

Although the loss of this physical body did not have much impact on Lin Fan, Lin Fan could just change it again. But to say that he has cultivated a body for many years, and he has also put a lot of effort into it, and it is too wasteful to be sent in to die like this.

"If you really can't do it, let's find a few people to go in and investigate!" Lin Fan pondered in his heart.

This is a good method, I don't know how many sinful people in the world, just catch a few of them, and let them atone for their sins.

However, the mortal body is too fragile, and after entering, it will be turned into dry bones by the black qi in a moment, and it cannot penetrate deep into the black qi.

This plan still doesn't work at the moment, so I can only talk about it later, and see if I can find a few humans with relatively strong strength to enter the enchantment and the like to check the news inside.

It's good to trap the black qi for the time being, Lin Fan has no way to take it at present, and he can't clear it at all. Lin Fan pinned his hopes on the upgrading of the world, and then the power of the world would grow a lot, and then completely eradicate this hidden danger.
