"Have you been charged yet?" Zhang Shengli often saw Liu Gan sitting on the roof of the tallest building in the prison, with a handheld computer with solar panels open beside him, but he had never turned it on. He guessed that this handheld computer must have some special significance to Liu Gan.

"No, the solar panels are too small, and the power required for computer operation is too high. Although the cloudy light can be charged a little bit of electricity, the light intensity is too weak. After charging for so many days, the power is exhausted before turning on the computer and entering the system." Liu Gan shook his head.

"Can't you try to connect other external power supplies? Several of the newly recruited team members know electronic technology." Zhang Shengli suggested to Liu Gan a few words.

"I have looked at them. They said that this thing is an integrated structure, the circuit design is very complicated, and it adopts encrypted packaging technology, without any markings or instructions, so I can't understand it at all, so I dare not power on the experiment casually. If I try randomly, I may burn the chip inside." Liu Gan shook his head.

"Is there important information stored in it?" Zhang Shengli looked curious.

"Well, what we got from a staff member of the Sanyu Company is related to whether we can teleport back to the real world." Liu Gan looked towards Qingpu Port. If the weather has been so cloudy, the handheld computer may only be opened again after being obtained from the main urban space laboratory.

"Then don't try it randomly." Zhang Shengli heard that the information is so important, so he didn't dare to suggest anything casually.

"What's the matter with you coming up to find me?" Liu Gan asked Zhang Shengli.

"About the construction of the prison camp, I want to hold a plenary meeting to brainstorm. I want to invite Mr. Liu to come and listen to it. I wonder if Mr. Liu has free time?" Zhang Shengli invited Liu Gan.

After Zhang Shengli followed Liu Gan, he found that Liu Gan's thinking ability was not as good as that of him, so it would be better to let Master Liu make a decision after discussing such a major event, so he would not have much pressure to execute it.

"I have time." Liu Gan stood up, put away his handheld computer and went downstairs with Zhang Shengli.

After a big battle with the corpse tide, Zhang Shengli felt that the significance of building a trenches around the prison was not very important. If it was dug too wide and too deep, it would require too much labor. If it was dug too shallow and too narrow, it would not have much effect, so he gave up this plan.

As the leader of the engineering construction team, Zhang Shengli decided to hold a plenary meeting to brainstorm, listen to the opinions of all team members, and discuss how to enhance the prison's defense. The slaves who had not yet been renovated also attended the meeting together, giving them a sense of collective honor and more conducive to their transformation.

"I think Brother Shengli's original idea is very good, just dig a city ditch! Dig every day. One day, the surroundings will be dug into a deep canyon, and the zombies will fall into it and cannot climb up. Then pour gasoline in and burn it, and no matter how many tides of corpses are burned out." Zhang Hua expressed his opinion.

"I won't discuss this for the time being. I'll think of something more practical, concise and effective." Zhang Shengli waved his hand.

"Can the prison wall be built higher? If not, build another wall on the periphery. If there are two walls, the defense ability is definitely stronger than that of one wall." Han Guangming also suggested a few words.

"This is very difficult, I'm afraid it's necessary to have construction experts to guide you, and the project volume will be very large, no less than digging a moat trench." Zhang Shengli shook his head after thinking about it.

"What about digging the tunnel? I dug a tunnel to lead a few kilometers away, such as the reserve warehouse. If the prison is surrounded by a tide of corpse, I can slip away from the tunnel. If there is no one in the prison, the tide of corpse will disperse by itself, and then we will come back from the tunnel." Zhao Meng contributed his ideas.

"This is good, you can consider it, but the project volume is still a bit large." Zhang Shengli nodded.

"I have a good idea, I don't know if I can say it..." A new member of the Lan surname who had successfully joined the latest transformation raised his hand.

"Say, just say it." Zhang Shengli encouraged the new team members.

"That... you can arrange a treadmill for a whole circle around the prison. After the zombies reach the wall, they can only stand still and can't climb up." The team member named Lan hesitated for a moment and then expressed his suggestions.

The scene was silent.

"This idea is also very good, but it's not realistic... We don't have so many treadmills... Let's continue to use our imagination." Zhang Shengli thought about it and praised the team member named Lan to avoid damaging everyone's enthusiasm for brainstorming.

"I have a suggestion, please refer to it." Liu Qian saw that no one had spoken, so he spoke.

"Master Liu, please tell me!" Zhang Shengli couldn't help but be overjoyed. What Mr. Liu said must be very practical and effective suggestions, which can help him solve big problems.

"I've been wandering around these days. There are large areas of forests to the west of the prison. The trees inside are growing very lush. Why not organize a cutting team to cut down the trees and build a circle of horse-rejecting piles on the outer edge of the high wall. Some wood is sharpened in front and is placed on the wooden piles. A small number of zombies come and are strung directly on top and cannot get close to the high wall."

"In addition, you can put more logs on the ground between the horse-repellent pile and the high wall. In winter, the ground is slippery and frozen. There is a tide of corpse breaking through the wooden pile defense. After rushing through the wooden pile, it is easy to fall when stepping on the log. It is similar to the treadmill principle of the team member just now. The ladder built by the zombies is not as solid as it was originally."

"In addition, once these woods are poured with gasoline, a wide sea of ​​fire will form between the horse-rejecting piles and the high walls. The tide of 10,000 or 20,000 corpse tides cannot pose too much threat to the prison. I am just thinking about these things temporarily. I can say it casually, and it may not be feasible. Your construction team should consider it comprehensively before making a decision." Liu Qian concluded his speech.

"Master Liu! His thinking is far-sighted, we can't catch up even if we are accustomed to it!"

"Yes! This is a good method, just follow what Mr. Liu said!"

"Master Liu is wise and wise, knows everything, and knows everything..."

"Master Liu is Zhuge Kongming's rebirth!"

"Master Liu, I love you!"

"Master Liu, you are my idol, cute..."

“…”

Hearing the sound of flattering horses and beards and the expressions of some female team members being crazy, Liu Qian decided not to participate in such a meeting in the future. He had already been a spoiled by his brainstorming.
