Fang Qi began to retreat, and did not stop until he reached the dense bat corpses behind his feet, starting from him, he was more than 50 meters away from the edge of the cliff on his side, and it was enough to accelerate the run.

Then, he took a deep breath and blessed the super double ability on the muscles of his whole body, and in an instant, he felt that his strength, speed, and endurance had increased several times, and his whole body was full of inexhaustible energy.

However, this is just an illusion, the muscle fibers of the human body have a limit, some people can bear the limit of high strength, some people have a lower limit, and the force is smaller. And once the force he uses exceeds the limit of his body's endurance, the result will definitely not be good, and it is very likely to strain muscle fibers, or even cause the rupture of internal organs, causing irreversible and devastating consequences.

However, at this time, he couldn't think so much, his eyes were always fixed on the opposite cliff, he cheered himself up with a low cry, and after raising his spirit to the best state, he gritted his teeth fiercely, lowered his body like a cheetah, and began to accelerate and run with all his might.

His speed became faster and faster, and by the end he had reached an exaggerated level where he could take more than two meters in one step.

When his speed reached its maximum, his feet were at the edge of the cliff, and if he took another step, he would fall directly into the river of magma hundreds of meters high. At this time, I saw that his legs were suddenly bent into ninety degrees, and all the strength of his body was compressed and injected between his legs, and after a burst of joint explosion, all the power suddenly burst out, and a sound of cracking in the ground came, and his body flew directly into the air like a cannonball, and catapulted away in the distance.

When his body rose to the highest point and began to fall, his mood slowly became heavy. Judging by the speed and height at which his body was now falling, by the time the force was completely gone, he still wouldn't be able to fall smoothly to the edge of the cliff on the opposite bank. And if you can't jump over, you'll fall into a lava river and take a painful magma bath.

At this critical juncture, he no longer had any reservations, the muscle instinct of his body quickly gathered all the internal force in his body on his hands, and the body in mid-air rotated 180 degrees, and the internal force on his hands erupted violently, so as to increase the distance of the long jump.

This method still worked, and his already falling body was slightly in the air, and the speed was a little faster than before.

And after doing this remedy, in a matter of seconds, his body had already fallen very close to the cliff on the opposite bank. However, it was clear that the cliff on the other side was in front of him, but it was still a little worse.

At the critical moment, he didn't have time to think about it, and almost instinctively reacted quickly, only to see him suddenly pull out the Miao knife on his back and stab it hard at the cliff wall in front of him.

A piercing sound of metal friction sounded, and then two-thirds of the blade of Miao Dao sank into the edge of the cliff, and his hands grabbed the handle of Miao Dao tightly, and the inertia of his body pulled Miao Dao down by more than half a meter, and finally stopped. When he recovered, he looked down and could only see the red magma tumbling and waves of heat rushing up, and he could already smell the smell of burnt shoes.

Immediately after that, he used both hands to use the Miao knife as a lever to flip his body over the cliff, and when his feet touched the ground, a sense of security came to him, and at the same time, every inch of his body muscles came with sharp pain, making him almost exhale in pain. The method of strengthening physical fitness with super doubling can only gain temporary strength, which is equivalent to overdrawing the potential of the muscles, and once the super doubling is lifted, the side effects of forcibly increasing strength begin to appear.

It took at least an hour for him to regain some strength, and when he felt thirsty, he took out the kettle only to find that there was not much water left, which was bad news for him. Before, before entering the cave, he didn't expect the temperature to be so high, and the pure water he had planned to drink for three days had bottomed out in less than a day.

"I don't know, how many unknown difficulties are waiting for me behind. He thought silently. The idea of turning back to replenish the water inevitably came to his mind, but then he was convinced that he had already come here, and if he did, all his previous efforts would be in vain.

He didn't know if he would be as lucky as this one when he jumped again, especially when the first jump had already consumed all his strength, and it would be difficult for him to use his heyday again on the second jump.

After tidying up, he continued inside. When he got here, the cave can no longer be called a cave, it should be called a cave, the cave has no fixed road, the potholes are full of potholes, up and down, he walked a few hundred steps inside, he stopped. It's not that he doesn't want to go on, it's that there's no way ahead.

He struggled and walked around, trying to find a substance that did not have the characteristics of the active substance, but unfortunately did not.

"Could it be that Lai Wenbang's speculation is wrong?" he couldn't help but wonder in his heart.

Listening to Lai Wenbang's words before, he imagined that the inside of the volcano group was a paradise scene, a place where birds and flowers were singing, but since he entered the cave, everything he saw was very different from what he imagined.

After careful calculation, from the time he stepped into the cave and walked here, he had walked at least ten kilometers, and he didn't even see a single hair of the active substance, which inevitably made him a little upset.

"Is there really no way to save Donald?" He felt more and more irritable, why did he do this thankless job, in the end he was still busy in vain, the depression in his heart accumulated more and more, and there was nowhere to vent, so he simply kicked the hard stone wall in front of him, and with a muffled sound, the debris fell from the stones, and several cracks appeared in the stone wall in front of him.

His heart moved, Fang Cai's voice was a little unusual, it seemed, there was an echo?

His eyes gradually lit up, and he kicked on the stone wall again, this time he heard more clearly, there was indeed an echo, and the echo was still coming from inside the stone wall. In other words, the inside of the stone wall is not solid, but hollow!!

Thrilled by the discovery, he kicked one foot after another on the stone wall, which became more and more cracked, and finally collapsed into a large piece of debris. However, what is exposed is a harder layer of soil. He was slightly stunned, then took out the Miao knife on his back, first poked a few holes in the stone wall in front of him to loosen the soil, and then kicked and banged with his fist.

The hard stone wall thinned inch by inch under his efforts, and he didn't know how long he dug into it, and he dug out another passage by himself, and the soil in front of him became softer and softer from hard to iron, and he could feel that he would soon be able to dig to the end, which made him look forward to more and more in his heart.
