An hour later, Gu Ming fell to the ground again exhausted, he didn't remember how many times he fell, at this time Gu Ming was soaked, sweat dripping from his chin drop by drop, and Gu Ming, who felt pain and powerlessness again, gritted his teeth and waited for the system to help him recover.

A green light appeared on his body again, and in an instant, Gu Ming seemed to be injected with endless strength, and once again propped up his body and stood up, now he can already stand up under this gravity, but although he stood up, every time he wanted to take a step, it was like a sting, and he couldn't take a step.

Every step seemed to drain the strength of his whole body, and after he stood firmly, he was just about to take another step, but suddenly felt the gravity pressing on his body completely disappear, and he was immediately relieved, and sat on the ground.

The physical strength of the body is made up, but it is hollowed out again and again to make up for it, or it still makes him fall into a state of extreme exhaustion, and his physical strength can make up for it, but the mental exhaustion is not so easy to recover, maybe the system can, but I don't know if he deliberately did not help Gu Ming recover, this is unknown.

After Gu Ming sat on the ground, he lay down again, and fell directly into a deep sleep within a few seconds.

In his sleep, Gu Ming seemed to have come to a void space, his back was cold, as if there were countless fierce eyes staring at him around him, and he felt the endless killing intent, which made him feel palpitations.

Phew-

A sound of breaking the sky sounded, Gu Ming instantly tensed his nerves, and quickly turned around, after going through gravity training, his body's reaction ability and response speed were many times faster than before, but he didn't know that he was asleep now.

Gu Ming turned around, his pupils contracted suddenly, and he saw a flying knife shooting quickly towards his heart, feeling the endless killing intent coming from the flying knife, Gu Ming was like a grasshopper on a hot pot, and instantly tensed his nerves, wanting to dodge the flying knife, but for some reason, he suddenly found that he couldn't move at all!

He couldn't even make a move, as if he had been imprisoned after that turn.

"No, no, I can't die!" Feeling the killing intent on the flying knife, Gu Ming let out a roar, the roar from the bottom of his heart was the despair of facing death.

The flying knife was getting closer and closer, and in an instant, it was only two meters away from Gu Ming, Gu Ming desperately wanted to move, but his body was not controlled at all, cold sweat kept coming out like mushrooms after the rain, and the fear of death in his heart became stronger and stronger.

Gu Ming stared at the flying knife in front of him, his pupils shrank sharply, at the astonishing speed of the flying knife, just two meters away, Gu Ming knew that if he couldn't dodge, the flying knife would penetrate his heart, and he would definitely die!

Gu Ming couldn't think about anything else in his mind at this moment, just thinking that he would never die, and for some reason, his thinking ability at this time seemed to be tens of thousands of times faster than before, his sister's face appeared in his mind, he couldn't die, he died, there would be no one to save his sister, at this critical moment, at this most critical moment, Gu Ming's whole spirit instantly tensed, and the strength of his whole body muscles and bones also burst to the limit, staring at this flying knife, he now has only one goal, one belief, that is, to avoid this flying knife, and not let the flying knife shoot his heart, otherwise he will fall into a state of no return, and will die directly！

However, at this moment, as if it had been controlled by an inexplicable energy, the flying knife instantly changed direction, passing past Gu Ming's ears, and the cold sound of the wind came into his ears.

"Dodge?" Gu Ming was shocked, and at the same time relieved, he didn't know how he dodged the flying knife, but he vaguely felt that at the moment of the last shot, he seemed to have an extremely powerful energy, and it was that energy that changed the direction of the flying knife.

Immediately afterwards, Gu Ming, who had just experienced life and death, relaxed at this time, and suddenly felt a sense of weakness again, and his vision became blurred.

What he didn't notice was that at this time, there was a powerful mysterious force constantly pouring into Gu Ming's mind, instantly integrating into every part of Gu Ming's body, under the baptism of this mysterious power, Gu Ming felt that the bones, internal organs, blood, muscles, and skin of his whole body were changing rapidly, and every cell was constantly changing, although Gu Ming was extremely weak at this time, he still felt that his body was transforming at a speed of a hundred times and a thousand times, and this energy and transformation made Gu Ming feel very comfortable.

All this came and went quickly, and it seemed like a long, long time, and I don't know how long it took, Gu Ming opened his eyes, and the moment he opened his eyes, there seemed to be a burst of essence in his eyes, if someone was here, he would definitely be able to find the difference between Gu Ming at this time.

His eyes are like the vast starry sky, deep, blurred, and give people an inexplicable sense of security.

"Huh—what is that power just now?, is that spiritual power?" Gu Ming muttered, and at the same time found that everything just now was a dream, but the changes in his body were still really felt.

"After an hour of gravity training, every muscle in the host's body has been greatly improved, and the bones have become stronger. ”

"And what I experienced just now is the spiritual power cultivation method provided by this system to the host, which constantly broke through the physical limit before, and at this time, the spiritual limit was broken, and the host's spiritual power at this time has reached the primary level. The voice of the system sounded, giving Gu Ming a clear answer.

Mental power primary?

Gu Ming thought about it, and then found that there were some more things in this secret room, many squares of the same size were placed on the ground, Gu Ming realized something, and directly concentrated and stared at one of the squares.

The continuous gathering of spirit made Gu Ming extremely uncomfortable, and he broke out in a cold sweat, and after more than ten seconds, Gu Ming was shocked to see that the block was indeed controlled by himself out of thin air.

"Is this the effect of spiritual power, it's too powerful!" Gu Ming almost screamed excitedly, and at the same time relaxed his spirit, and the block fell to the ground again.

Immediately after, another stream of information poured into Gu Ming's mind, and after digesting it, Gu Ming realized that it was actually a technique and explanation for the use of spiritual power.

Gu Ming continued to learn how to use spiritual power according to the usage skills provided by the information, and at this time, there was a powerful gravity suppressing him, this time the difference was that the gravity was not pressing on his body, but in his mind.

This gravity made Gu Ming almost unable to use his spirit, and as he used it little by little, the consumption of his spirit was also extremely terrifying.
