But there is something more dangerous than corpse blood. That is, the mercury under the feet is getting denser and denser. For the first time, Chen Si felt that his feet were as heavy as if they had been filled with lead water. If it weren't for the frequent twitching of his feet, they would have been fixed in mercury.

Gu Fengchun is not easy, although the military thorn is sharp, but the copper wall around it is not so easy to cut open. The main reason is that the edge of this military thorn is too thin, and it can only be cut by using the end, and the military thorn is not short, and it is very inconvenient in the process of use, Gu Fengchun did not dare to use too hard, for fear that he would break this treasure. It took a while to cut a shallow depression.

Chen Si's eyes became anxious. He said repeatedly: "Fengchun, hurry up!" Then he said, "Lift your feet quickly, and don't stop, or you'll be in trouble......

Gu Fengchun was so angry in his heart that he was annoyed by Chen Si for a while, and glared at Chen Si fiercely. It was the first time he felt that Chen Si was really verbose. You're always nagging in your ear, how can I be quiet and deal with it! You've been upset! After glaring at Chen Si, Chen Si really quieted down. But this is only relative to the ancient style. Chen Si's eyes were half-squinted, and he pulled the trigger of the machine gun again towards a place about twenty meters away. This time, the target was obvious, and when the corpse was moving, a mark appeared on the mercury, and it seemed that something was approaching.

Chen Si is very good at saving bullets this time. I just want to teach this corpse a small lesson and drive it away. After all, there are not many bullets, and if you miss one shot, you won't have one. The corpse didn't seem to realize Chen Si's good intentions, and he rushed over very shamelessly. At the same time, Chen Si also found that the mercury in the distance also fluctuated, and it seemed that more corpses and blood had appeared.

"What the hell." Chen Si said fiercely. After a large burst of bullets was fired, the nearest corpse blood stopped and did not move. However, the fluctuations of mercury around him told him that at least more than ten corpses were approaching.

"Damn it!" Chen Siyi gritted his teeth, and the bullet quickly swept out a large area. However, due to the relatively large coverage area, the accuracy of the sweep is far less accurate than that of the individual design. However, Chen Si was not stunned, and after shooting back and forth a few times, the situation suddenly improved a lot. It's just that the bullets in the magazine are also swept away.

Gu Fengchun suddenly exhaled and said, "Chen Si, come up quickly." "He's carved eight holes in the copper wall. The supply climb is sufficient.

"You go up first, I'll deal with these things first!" Chen Sitou didn't look back, flipped his hand over, took out a semicircular magazine from the backpack, and installed it at once. Chen Si knew very well that if he and Gu Fengchun climbed onto the copper wall together, the backs of both of them would be exposed, and in this way, once the corpse blood creature attacked, both of them would suffer.

Rather than both of them being in danger, it is better for one person to make a sacrifice. Chen Si weighed the pros and cons and made a decision immediately.

Gu Fengchun frowned, he understood that this was a move made by Chen Si to protect him. "And what do you do?" Gu Fengchun said.

"I can only see one step at a time." Chen Si didn't have a choice. But there was clearly optimism in his tone. "Hey, something is wrong!" Chen Si's tone suddenly became happy. He saw that the corpses around him seemed to be frozen. But the joy soon turned to solemnity. Because he found that his feet seemed to be stuck with strong glue, and he couldn't move.

"Feng Chun, pull me!" Chen Si's face changed, and he stretched out his hand in the direction of Gu Fengchun. Fortunately, Gu Fengchun had already jumped into the hole he dug out, otherwise he would be no different from Chen Si at this time.

"Okay", Gu Fengchun immediately grabbed Chen Si and wanted to pull him up. But Gu Fengchun seemed to overestimate his strength, and he couldn't even pull Chen Si.

"It's so heavy!" Gu Fengchun said in surprise.

"Isn't that nonsense? If it doesn't sink, I need your help! Chen Si said angrily. He felt as if his feet had been poured concrete, and the concrete had begun to solidify.

"Come on, don't pull it!" Chen Siwei screamed. Gu Fengchun's strength is not small, pulling his arm is faintly painful, but his feet are not moving. If this continues, he may not be able to pull him out if he pulls his shoulder out of his place.

Gu Fengchun looked at Chen Si with a little crying and laughing, not knowing what to do. Chen Si didn't panic, he felt that the mercury around him had become extremely hard. Moreover, the color of the mercury has also changed. From the silvery-white color of pure silver, it gradually changed to a golden-yellow color like gold.

"This is ......" Chen Si looked at the liquid mercury in surprise, turning into a golden solid, and it seemed that the height of the mercury had suddenly become a lot lower.

"This is gold?!" Chen Si said again in a suspicious tone. Gu Fengchun was rarely able to hear Chen Si speak in this tone. At this moment, the two legs were tightly wrapped in gold, and Chen Si was unspeakably uncomfortable.

He stroked it with his hand, looking incredulous. Because the feel told him that this was gold, and it was extremely pure gold.

"Turning stones into gold!" Chen Si said with emotion. Wrapped in so much gold, Chen Si, who has never taken money seriously, was also a little shocked. If he hadn't seen it with his own eyes, he would never have believed that mercury could really turn into gold, although it could be explained theoretically.

This theory, Gu Fengchun once told him that the difference in the number of protons between gold and mercury is only one, and if the mercury is irradiated with neutron rays, the mercury will be reduced by one proton and become gold. However, neutron rays are not readily available and need to be generated through a neutron source, and the neutrons produced are kept for up to 15 minutes. Moreover, the process requires a lot of money, and can only be experimented in the laboratory, and if it is used as a tool for the wholesale production of gold, it is definitely a loss-making thing.

But the mercury in front of him was so simply converted into gold, which had to make Chen Si dumbfounded. This is the legendary turning stones into gold! Chen Si, who lived for more than 1,500 years, was also the first time he had seen such a situation.

Gu Fengchun twisted his head, and forgot to pull Chen Si. Looking at the gold, Gu Fengchun suddenly said stupidly: "Chen Si, are your feet still there?" He knew very well that the process of this kind of physical change would be accompanied by a strong energy reaction, either emitting heat or absorbing heat, no matter which one of the guests was, it was enough to wipe out Chen Si's feet.

"Aren't you talking nonsense?" Chen Si shook his legs. He could feel the pressure of gold on his feet. It's a very uncomfortable feeling.

Yesterday I took a ride to my hometown and broke off for a day. There is no time to make up for it for the time being. I'll make it up when I'm done. I beg your pardon!
