"I think this place is good!" as soon as Mac said these words, he eagerly began to prepare the training area.

Sitting cross-legged, Mac made himself comfortable so that he wouldn't feel the unevenness of the floor and began to practice the Energy Core Formation cultivation technique.

Although this technique was difficult to master at the tree level, which was the lowest level, it was the most suitable for the 3rd stage of Energy Core Formation.

The cultivation technique consisted of using world energy, which the cultivator, thanks to the peculiarities of his body and various techniques, had to absorb and, in the process of absorption, combine with his body by moving world energy in the body and, as a result, form spiritual energy in the lower abdomen in the form of a nucleus of energy.

And although in the process of this absorption spiritual energy was generated in the body, the physical strength, reaction, speed and overall strength of the cultivator's body increased.

However, such absorption was unusual for the human body, because it went against nature itself, so quite often during cultivation, cultivators suffered painful sensations that ranged from general exhaustion to unbearable pain accompanied by loss of consciousness.

At the same time, when cultivators advanced to the next stage or level of cultivation, they experienced an incredible surge of strength, which increased their physical strength, endurance, agility and body strength, and sometimes even healed injuries in the body, both external and internal.

Moving one step forward to the next stage of cultivation, namely Stage 4, Mac took an old scroll out of his shirt pocket and opened it.

This old scroll was a sutra called the Wild Beast Heart Sutra. The sutra was made of a large rectangular piece of wild beast skin.

The edges of the sutra were frayed and even torn in some places, and the outside of the sutra was silver, like the colour of the skin of the animal from which it was made.

The letters in the sutra were small and golden in colour. Mac did not know the rank of the sutra, or where it came from. He had taken it from his grandfather's room.

It was in a locked chest at the very bottom of the closet in his grandfather's room, where he usually kept all sorts of junk.

Without being distracted by the movement of spiritual energy in his body, Mac began to read the sutra carefully. He did so as he had done on previous occasions, slowly and gradually.

For when he first took the sutra out of the chest and began to skim through it, he had felt the incredible hidden power contained in the small golden letters.

He continued to read without paying any attention to it, and when he had finished reading the first sentence, he felt weak in his legs, and the next moment his legs gave out and he fell to the ground.

But in time he grabbed the edge of the table and thus avoided falling.

Realising the connection between the sutra reading and the weakness in his legs, he took the sutra from Elder Strai's room and carried it with him from then on.

The next day when he decided to read it again, Mac sat down cross-legged and gradually began to read the first sentence.

And from that day onwards, he gradually increased the number of words in the sutra each time he read it.

And so he did for the last two weeks.

Not only did this approach allow him to avoid exhaustion in his body and increase the size of the text from one sentence to one paragraph, but Mac also began to feel certain changes in his body.

The changes were in the spiritual energy itself, which gradually ceased to be light and airy, as it usually was after the cultivation technique.

Instead, it was more and more like molten metal, moving slowly and smoothly through the energy channel of his body.

With each sentence recited, the spiritual energy became heavier and heavier in Mac's body.

And at the same time, the energy became purer each time, as if each sentence of the sutra was burning the impure energy out of Mac's body with fire.

Mac did not know the whole meaning of the sutra, because he could not read it completely, because he felt that only gradually, sentence by sentence, the meaning of the sutra would be revealed to his mind.

Mac also did not know what it could be used for or where his grandfather, Elder Stray, had gotten it from, but after each reading, his spiritual energy became more stable.

Although the sutra was not a cultivation technique, it could improve the quality and purity of energy, which made the spiritual energy itself stronger.

But on the other hand, it also slowed down the process of accumulation and movement of spiritual energy in Mac's body, which in turn only widened the gap between him and his classmates.

After practising for an hour, a dozen drops of sweat slowly trickled down Mac's tense face, and the same was true of his body.

Although this was not a problem compared to the feeling of molten metal slowly spreading over your body, even so, Mac continued to read the sutra.

There was a hole in the upper right corner of the roof of the room where Mac was staying, through which you could see the large trees of the dense forest that surrounded the house.

Or, from the branches on the tree, one could see what was happening in the ruined house.

At this time, an unknown person was standing on a tree branch a few steps away from the house. He was wearing a long white robe, and his thick grey beard was hanging loosely, swaying in the wind.

The person's gaze was directed exclusively through the hole in the roof of the ruined house at the young disciple of the Sect.

Its eyebrows were raised and its mouth was open in surprise when it saw the Sutra.

She involuntarily said
