This signal made him very happy in his heart, and he hurriedly continued to tinker with it, digging the range wider, and then constantly digging upward.

Now he was in good spirits, and he had inexhaustible strength up and down, so he kept pounding up three or four meters anyway, leaving a stepped groove on the left and right of the passage, and he kept digging up pieces of dirt, and then went down to the ground and moved some of the dirt to both sides of the passage.

The movement was slight and didn't make much noise, and he emptied his backpack to retrieve the excavated dirt and moved farther down the tunnel.

In order not to disturb Wang Shi's rest, he greatly reduced the speed of digging in this method, and after two hours of repeated excavation, he actually dug the passage upwards for more than 30 meters.

Looking at such a masterpiece, his heart was full of anticipation and apprehension.

The expectation was that he would be able to dig some passages through them, or that he would be able to dig them up as soon as possible, but he was worried that the passages would be deeper than he expected, that it would take a long time to dig through, or that he would accidentally dig into the rock layers, which would be a tragedy.

At a height of more than thirty meters, he had some difficulty grasping the movement in the passage below, and he was worried that the sleeping Wang Shi would be in danger, so he had to stop.

Seeing that Wang Shi was still sleeping unharmed, he breathed a sigh of relief, cleaned his backpack again, and put the food and water back into the bag.

The medicine and the like were almost consumed, and he examined the wound, which was already healed, and there was only a very shallow red mark on the wound mark, as if it had been scratched by someone with his fingernails.

This immunity system and recovery system are very powerful, and such injuries are stimulated by deep sleep, and the effects of the two systems are completely brought into play.

After observing the passage for a while, he found no sound or vibration, and this area made him suspect that there were only two of them left.

I don't know what happened to Chu Lang and Li Tianqiang? He still hopes to find it as soon as possible and escape together.

Time was slowly passing, Lin Zhen tried the method of qi induction to continue to guide the rich internal energy contained in the meridian acupoints, he felt that this world was very wonderful, he had never thought that an ordinary person could still practice this mysterious internal energy breath.

"Could it be that as described in the martial arts before, there were such people in ancient times?"

But it doesn't seem like there is a need to go back to ancient times, before I met the group of inheritors of traditional martial arts in Huaxia Kingdom, they also formed a martial arts alliance, and the people in the members can practice the breath of internal strength, he now believes that a punch can shatter a stone pillar with a diameter of one meter, such a person, should be a master of practicing martial arts.

After practicing for two hours, he stopped, and some of the tiredness and exertion left by digging the passage before were all gone, and now he had a feeling of resurrection with full blood, and he was able to cause a method through practice, with the help of the internal strength in his body to buffer the tiredness and restore his strength and spirit.

"This internal energy is really a good thing, and I don't know how to explain it with science?"

"Is it qi, is it energy, is it life force? Or mental power? ”

Or is this inner strength a mixture of human vitality and spiritual power, and an energy of the origin of life? After countless pioneers have gone forward and succeeded, and constantly tried, excavating and stimulating the most authentic life origin energy of human beings? ”

This question made him fall into contemplation, and he had to use his life's knowledge and experience to try to find reasons and evidence for explanation, and such contemplation was boundless and endless.

Before he knew it, he was pleasantly surprised by the sound.

"Are you awake? There's still time, go back to sleep......"

He saw Wang Shi wake up and hurriedly said.

Wang Shi glanced at the time on his phone and said, "I have slept for eighteen or nineteen hours, and now my spirit has recovered, but my stomach is so hungry and thirsty." ”

He was suddenly stunned for a moment, looking at what seemed to be an extra layer on the ground, and then he looked back and forth, and exclaimed, "Boss, when did you have an extra layer of dirt here?" ”

He looked around, and suddenly saw a big hole in front of him, hurriedly walked over, turned on the searchlight, and was shocked: "Boss, you found the passage?" ”

"Is this an escape route?"

Lin Zhen shook his head and said: "This is a passage I dug out, but it is only more than thirty meters high, and I haven't seen the end yet, and I don't know how deep it is where we are now." ”

He briefly told the things before and after, and Wang Shi was stunned for a moment when he heard it, this is also amazing.

"Boss, aren't you tired?"

Lin Zhen smiled and said, "It may be that those infected viruses have changed my body, and now my body seems to be stronger than before." ”

Wang Shi asked, "Haven't those infected viruses been resolved?" ”

Lin Zhen shook his head and said, "I don't know, but there is nothing uncomfortable now, so far there are benefits, as for the disadvantages, let's talk about it later." ”

Wang Shi said: "After going out, you should go to a big hospital as soon as possible to check it, and it is not good to leave potential hidden dangers." ”

Lin Zhen nodded and said: "Let's solve the matter in front of us first, eat some dry food and water first, replenish our physical strength, we have to dig the passage directly up to see if we can dig all the way up." ”

After more than ten minutes, the two cleaned up and climbed directly up to the passage.

The distance of more than thirty meters is still very high, and it takes a lot of physical strength to go back and forth, so Lin Zhen directly dug a very open groove on the side of more than thirty meters, let him rest there, and then rotate when he is tired.

There are two people taking turns to rest, which is also very good and very efficient.

Lin Zhen dug six or seven meters first, but still didn't get through the end, so he could only climb down and give Wang Shi alternately, so that he could dig slowly.

He descended the large stone passage and pushed all the accumulated dirt to the left and right sides of the passage, making sure that the passage was not blocked.

This is a way back, after all, if they keep digging up the silk road of rock formations, they still have to go back to the passage and find another way to leave.

After pushing away the soil, the Wang Shi on it had just dug seven or eight meters, and his physical strength was somewhat depleted, so he returned to the groove at a height of thirty meters to rest.

Lin Zhen climbed up to dig up the soil, and dug more than 50 meters in this way, which added up to 80 meters before and after.

However, they still haven't opened this passage, it seems that it is very deep from the ground, such a distance, in some places in Huaxia Kingdom, they have been able to dig a well, but now, they have to continue to dig.

"The place we're digging now can't be a mountain, right?"

Wang Shi was a little suspicious.
