In a large stone house in the City of Light, Cong looked at a cylindrical glass vessel with a faint green light in front of him. This huge thing was sixty meters tall and about ten meters wide. In this container, there were loads. It was a green liquid, and you could see bubbles rising up one by one. "Cong, do you really want to use this? Isn't it a little too cruel." Xun stood behind him, his eyes full of worry.
"Cruelty. This is just the beginning. Xun, you are still too kind. But don't forget how hateful human beings are." Cong turned around and looked at Xun. A gentle look finally appeared in his cold eyes.
"Then what should we do with them? You don't really want to kill them, do you?"
"They. I will only kill those humans. I will temporarily imprison the other tribesmen. I want these humans to be sacrifices for our great plan. It is also an honor for them to be chosen as sacrifices. Their names may be It may not be passed down by our dwarf empire. You think so. Hahahaha..." Cong touched the huge cylindrical glass vessel with one hand. The gentleness in his eyes disappeared, revealing a fierce look.
Xun looked at Cong's back. She felt that Cong was no longer the person she was familiar with. Maybe her support for him was a mistake.
………
Hou Kai put his hands flat on his chest. After he said that he had a way to get out, everyone looked at him to see what method he would use to deal with this thing that was harder than bricks and stones. It was on his palms. There are two golden spells floating. The air around the spell on the left is distorted. The spell emits a circle of red light. The one on the right is a blue light that emits cold air. One is ice and the other is fire. As the leader, Hou Kai, after learning 100,000 copies of skills, can use all spells with attributes. However, the prerequisite is that the level must meet the usage requirements.
He stretched out his left hand, and the talisman erupted into a fierce flame. He dry-fired the dense pillars of the stone prison until the small stone pillars were burned red. Hou Kai immediately retracted his left hand. Then he stretched out his right hand, and the ice talisman shot out. A line of white smoke and hot air suddenly began to drop sharply. The red pillars were affected by the cold air and returned to their normal appearance. Hou Kai continued to repeat the heating and cooling process.
Yu thought that Hou Kai's brain had been beaten stupidly by Cong. He couldn't help but asked, "What are you doing? Heating and cooling for a while. Is this what you are doing?"
After looking at it, the girls knew what method Hou Kai was going to use to break open this solid stone prison. Xu Mao Mao explained to Yu, "He is using the principle of thermal expansion and contraction to destroy this stone pillar." "
"Heat expands and cold shrinks. What's the principle?" Yu asked curiously.
"You don't even know this, do you?" Xu Mao Mao was stunned by his words this time. Logically speaking, this technologically advanced mountain dwarf should know this. How come even a primary school student knows this? How could they not know the reason? She asked Yu again, "Are you really not aware? Or are you pretending not to know?"
Yu shook his head with an ignorant look. Xu Mao Mao touched his chin and secretly guessed, "It seems that there are differences between dwarf technology and human technology. It seems to be of great research value."
"Let me tell you." Yu stood up. She is a young talented woman. It is natural to explain this principle. "The method Hou Kai uses now is called thermal expansion and contraction. When an object passes through a high temperature After heating, the molecules of the substance will accelerate and the object will expand. On the contrary, after encountering cold erosion, the movement speed of the molecules will decrease and the object will shrink. He is now constantly making the stone pillars undergo rapid expansion. And the process of rapid shrinkage. The purpose is to break the molecules of the stone pillars."
"There is such a simple principle. Why haven't we discovered it before..." Tian's interest was aroused. Unknown technological civilization is the most attractive place for researchers. Xiang You began to ask if there is anything else Other principles.
While Hou Kai listened to them talking, he focused on his hands, controlling the conversion between the fire talisman and the ice talisman. After about the tenth heat and cold exchange, obvious cracks appeared on the originally smooth black cylinder surface of the stone pillar. The small fine lines produced a large number of cracks on the twentieth time. At this time, Hou Kai stopped the movement of his hands, took back the charms on his hands, turned around and said to them, "Now this stone pillar only needs to be used a little bit." It should be able to be easily broken with strength."
"Really? Then let me give it a try." Yu walked up to the stone pillar, rubbed his hands together, and shook them a few times. He moved his hands, clenched his fists, and punched the cracked stone pillar. After being beaten down, the stone pillar was broken into pieces of different sizes and fell to the ground under Yu's powerful fist.
"It's really amazing." Wen Ye praised.
"It's so handsome. I didn't expect that I could actually break the material made of black stone with my bare hands. It feels the same as having sex with a woman." Yu punched a few more times and broke the pillar that also had cracks.
"How did you come up with this method?" Xu Mao Mao asked.
Hou Kai smiled at her, "Of course I have to thank you for this. It's not like you said just now that you put your hot face on it and melted the stone pillars. I may be struggling with how to get out now." In fact, the simpler and easier to understand things, the better. The easier it is to be forgotten. "Okay, let's chat later. Let's get out now so we can teleport out and regroup to prepare for a counterattack." Hou Kai took the lead and exited the stone prison through the gap made.
After everyone came out, Hou Kai was about to use whatever force he wanted. At this time, Hou Kai stopped him. "Can you rescue the other tribesmen imprisoned here? I think with their help, we can take back the initiative." .”
Hou Kai thought for a moment and nodded in agreement, "However, it will take a lot of time to rescue them one by one. I'm afraid they will be discovered by then."
At this time, Tian said, "This is easy to handle. You and I will go to my laboratory later. I will get you a good guy."
"Oh...~" You have piqued Hou Kai's interest. He first set up a teleportation point here and sent everyone back to the secret base. Then he and Tian went to the laboratory.
With a flash of silver light, Hou Kai and Tian teleported to Yaoguang City. The place was much deserted than when they came here. Originally, you could see a few dwarves coming in and out, but now it was hard to see a single figure for a long time, as if it was an empty city.
"Let's go. Let's go to the root of the tree first. Teleport directly up there."
