The next day, as soon as the sky was bright, Xu Lin had already woken up, and kept watching the movements of the zombies outside the window, until he was sure that all the zombies were gone, he immediately went out, packed up the "prey" on the trap, and prepared to start implementing his plan.

For Xu Lin, who did not have any knowledge of architecture, it was impossible to build the fence very professionally, but he still knew some basic knowledge.

To build a wall that can resist zombies, the foundation is very important, so before building the wall, Xu Lin had to start digging the foundation more than a meter deep.

Xu Lin alone does not have the ability to build a large area of the wall, but the construction area of the villa is too large, plus the lawn in front of the villa, it is at least 40 meters by 50 meters.

"My God, that is, I have to dig a trench 180 meters long and more than one meter deep by myself, isn't this killing people!" Xu Lin roughly calculated his workload, just digging the foundation, he estimated that he would be exhausted to death.

"Forget it, it's okay anyway, just dig it, and when the wall is built, then my safety factor will be very high."

In the end, the benefits brought by the construction of the wall made Xu Lin have to face the difficulties.

"I just finished working as a porter and am going to be a miner, and I find that I, the creator of the Ten Thousand Worlds, who has terrified even the powerhouses of the universe, is really sad." Xu Lin complained as he began to do his work.

Digging the foundation is undoubtedly a manual job, Xu Lin is not a machine, it is impossible to dig all the time, just dug more than two meters, and he has already felt blood blisters on his hands.

"Damn, it's harder than you think."

Xu Lin originally planned to dig a circle according to the scope of the villa's lawn and then carry out the next step of installing metal pipes, but now it seems that he may have to change his plan.

Because the blood blisters on his hands were too painful, I was afraid that he couldn't keep digging them, so Xu Lin planned to endure the pain in his hands, dig the length of a metal pipe, and make the first "metal wall" first.

At least when making the metal wall, he doesn't have to hold a shovel in his hand anymore.

All morning, Xu Lin was digging a pit, and Xiao Hei was also on the side, using his claws to plan, the work efficiency was not low, at least one fifth of the workload was shared for Xu Lin.

In this way, one person and one dog, working until finally eleven o'clock, a large pit nearly four meters long and about one meter and two meters deep finally appeared on the ground.

The width of the pit is not wide, only about half a meter, and the metal pipe does not need to be too wide to fit down, but Xu Lin must stand in the pit to dig the foundation to a depth of more than one meter, so the width of the pit must at least allow him to stand down.

The foundation is dug up, the following is to make a "metal wall", the metal pipe removes the underground foundation part, the ground height is about two meters three, Xu Lin intends to put a metal pipe horizontally underground, and then weld two metal pipes at both ends as the frame of the wall, after burying the foundation with soil, the above-ground part is welded between the two frames with ten metal pipes to form a metal wall.

The diameter of the metal pipe is about five centimeters, and only ten metal pipes are used to form the wall, indicating that the metal wall still has gaps, but it will not exceed fifteen centimeters, as long as the zombie's head cannot squeeze in, the zombie will not be able to pass through the metal wall through the gap.

After designing the plan, Xu Lin immediately began to work on the first metal wall. First of all, the three metal pipes formed a "concave" shape, the top of the metal pipes was connected end to end with a flame spray gun, welded together, and an hour later, the frame of the metal wall was completed, and Xu Lin put the bottom of the frame down and put it into the soil pit.

After burying the soil pit, Xu Lin repeatedly crushed and compacted the ground. This step is very crucial, although Xu Lin has arranged the underground part of the metal pipe very long, one meter and two lengths, enough to one-third of the entire metal pipe, but without cement reinforcement, the foundation is not firm, only constantly tamping the ground.

Originally, Xu Lin wanted to start making "walls", but thinking that the foundation was not yet solid, he finally gave up.

"The ground is not firm enough, and it needs to be reinforced several times." Xu Lin shook his head, he looked at the several blood blisters he had been injured, and it was impossible to dig a new dirt pit.

"Damn, everything is easy to think about, but difficult to do, and I have only made a framework until now, and I have encountered so many problems!"

Even if he felt a little frustrated in his heart, Xu Lin also knew that making a wall was by no means an overnight thing, he couldn't be in a hurry now, the foundation was not solid, and the wall would fall down as soon as it was pushed, so there would be no protective effect.

"Xiao Hei, let's rest today, at least I have experience, and the speed should slowly get faster in the future." Xu Lin cleaned up his construction site and returned to the room with Xiao Hei.

"Xiao Hei, I'll help you wipe your paws, it's all dirt." Xu Lin took a dry towel and helped Xiao Hei clean the dirt on his paws and chest.

After briefly dealing with the blood blisters on his hands, Xu Lin looked at his watch, it was only 2 o'clock in the afternoon.

After hesitating for a moment, Xu Lin dispelled the idea of going out to search, "I will have to strengthen the foundation again in a while, I will be lazy today, I won't go out, I will have a good rest and rest, and strive to speed up the progress of the project tomorrow." ”

Every hour, Xu Lin would go out and use a shovel to slap the ground firmly, and as for the rest of the time, he had nothing to do but play with his Ten Thousand Worlds Creator Mark.

The imprint is still empty, every time he harvests a new energy crystal nucleus, Xu Lin will check it carefully, after all, this kind of mysterious imprint from the depths of the universe may not necessarily be according to the counting habits of human beings, it may not be the habit of using numbers like 1, 10, 100 as the dividing line, maybe when it accumulates to 6 or 7 units of energy, people will have new items to create. However, every time Xu Lin opened the seal, he was disappointed.

However, during this time, the repeated summoning of the imprint made Xu Lin gradually feel that he was becoming more and more proficient in controlling the imprint, and when he opened a certain functional ball, sometimes, the ball did not need to project a complete light curtain at all, and Xu Lin could already know some of the content presented in his mind.

Xu Lin's explanation for this is that the Ten Thousand Worlds Creator Mark is connected to the brain, and he couldn't control the mark very skillfully before, so the mark displays the content in the form of a light curtain, but during this time, as his control proficiency improves, the mark is slowly starting to display the content directly in his brain.

Whether his guess was right or not, Xu Lin's feeling became more and more obvious as the number of summoning marks increased.

"I don't know what the use of this slight change is, anyway, I can't do anything now, so let's practice controlling the ball." Xu Lin also hoped that he would become stronger as soon as possible, but helplessly, he couldn't do anything now, so he could only practice this kind of chicken rib ability.

At half past five in the afternoon, Xu Lin slapped the ground firmly for the last time, it was not early now, the zombies were about to come out for activities, he didn't dare to stay too long, and went back to the villa directly.

It was not yet six o'clock, and Xu Lin had already heard a zombie shouting outside the door, "Hungry, hungry." ”

"Zombies came out earlier than before." Xu Lin leaned back on the sofa and continued to contact the control imprint.

"Dangdangdang" A sharp knock on the door made Xu Lin almost jump up from the sofa.

"Anyone? I know there are people here, they are coming, please, let me in, save me! Please! Outside the door, a panicked voice sounded.
