Su Mu's speed was still very slow when he started, but as time went by, he became more confident, and the speed of the engraving continued to increase. In the end, only the afterimages left by the branches waving in the air could be seen.

The lines on the root of the tree were twisted and crooked, seemingly motionless, and the viewer had a splitting headache and was upset.

But when Su Mu's pen changed, and the last stroke was completed, connecting end to end, the distorted lines suddenly changed, like a dilapidated beggar turned into a noble king.

At this time, the lines seem to be natural. At first glance, they just feel natural and harmonious, but the more you dig deeper, the more you can feel its mystery, which faintly reveals the truth of heaven and earth.

This is Lingwen!

In other words, it is a higher derivative form of Lingwen, the spirit array.

Even ordinary people who have not awakened after the recovery of spiritual energy can gradually become extraordinary after learning!

It is strange to say that when the engraving of the spirit array is completed, these penetrating lines miraculously disappear and hide, and there is no trace of it anymore. No matter from which angle you look at the engraved tree roots, you take it for granted. This is what it looks like.

Very harmonious and natural.

Satisfied, Su Mu put down the tree root and took a rest.

Even though he has great spiritual power, he was still exhausted after engraving this spirit formation.

Of course, this is also because this spiritual text is the first time I have come into contact with it, and I am not even familiar with it, and it is the deep content derived from it. Naturally, I have to be careful to avoid any mistakes.

You must know that the engraving of the spirit array is very strict, there must be no pause even for a microsecond in the middle, it must be completed in one go, and there must be no mistakes in the direction of the strokes and key energy nodes, otherwise the impact will be great.

It may just be that there is a place where the turning is not round enough, and the effect of this spiritual array will be greatly reduced after the engraving is completed. If more critical energy nodes are involved, it may directly cause the spiritual array to fall short and have no effect.

These harsh requirements lead to the extremely high threshold for the spiritual formation, and the high requirements for talents, which means that its promotion is difficult. It may be very difficult for ordinary people to use the practice of spiritual scriptures to reach the extraordinary.

But in any case, it is always a path that can be passed. Compared with awakening by talent, it can give hope to the vast number of sentient beings.

Su Mu didn't rest for too long, the Lingshi Mine is still waiting, it can't be too long, Su Mu immediately began to send his spiritual energy into the roots of the tree.

The spiritual mist in his body began to consume rapidly, and this small tree root actually consumed nearly half of his spiritual energy!

What a ruthless juicer!

Su Mu was also careful in the process of conveying the spiritual energy, because it was also very particular. This spiritual energy had a fixed route, and if it was messed up, it would also cause the spiritual array to not be able to exert its original effect.

Su Mu frowned slightly, and muttered in his heart: "This thing is really troublesome, and it needs to be improved."

But although he said so in his heart, he also knew that it might be a long time before he really wanted to implement it.

When the roots stopped swallowing Su Mu's aura and reached a saturation, the roots began to emit a dim light, which was really beautiful.

Su Mu's heart flashed with enlightenment, knowing that the time is now ripe.

There is only one last step left.
