Early the next morning, Su Yang quietly returned to the high-tech zone, and no one found that Su Yang had sent Nong Wen away, and the base was still a normal scene.

Found Shahai, Su Yang handed over the formula given by Nongwen, Shahai only left a sentence and left in a hurry, now the first task is to send the formula back to the military region, so that Professor Lian can distinguish the authenticity, and he is not at ease when he hands it over to others, so Shahai can only go by himself.

Su Yang smacked his lips, still thinking about what Shahai said about the test and reward before, and he didn't know what the hell was going on.

Idle, Su Yang decided to go to Li Guangliang to have a look, originally wanted to find Zhang Xinghan, but I heard that Zhang Xinghan took Lin Hu and Li Dong yesterday, and the two teams went out together, and they haven't come back today, but according to Wang Shou, they are quite safe, nothing happened, which also makes Su Yang feel at ease.

"Coming?" Li Guangliang is directing the workers to install iron fences, the so-called iron fences, in fact, I don't know how many companies' iron gates were demolished.

In the bright plan, workers dug into the ground to a depth of one meter, then inserted an iron gate into it, and then filled in the holes, so that a 2 to 3 meter high iron fence appeared. Some of the iron doors have relatively large gaps, and the workers use steel bars to penetrate through the gaps to prevent zombies from getting in, and for the sake of insurance, all the iron doors with large gaps are installed together, and in addition to the steel bars, the iron doors are also blocked behind with stone bricks and cars full of sand and gravel weights.

The remaining iron gate gaps are denser, so it's not so troublesome, of course, if it's a person, climb or crawl in, but it's mainly to prevent zombies, and there will be sentry posts in these places, so as not to be negligent.

And the opposite side of this iron wall, in fact, is still the current base, but the role here is the exit of the inner city and the outskirts, so there is no fanfare to build.

Su Yang nodded at Liguangliang, looked at these gradually completed fortifications with emotion, and admired Liguangliang.

Li Guangliang was still a little dissatisfied, complaining that there were not enough things, and he could have made the fortifications more solid, but Wang Shou took away a large number of metal objects, saying that they were in urgent need, and there was no way but to make them like this.

Su Yang comforted Li Guangliang a few words, saying that Wang Shou really needed a lot of metal, and it was also for the sake of the base that Li Guangliang's grievances were calmed.

After the contraction of the base left very few exits, relying on some of the original buildings, the defense appears more dense and compact, all kinds of large excavators, bulldozers work day and night, sometimes in order to block a hole, even some low-floor buildings are bulldozed, all kinds of building materials continue to be transported to the designated area of the light.

When Su Yang was still discussing with Li Guangliang about the location selection and use of materials for some fortifications, Lian Yu came. Lian Yu, who looked puzzled, saw Su Yang, and called Su Yang away without saying a word, leaving Li Guangliang alone with a wry smile.

"What's wrong?" Su Yang looked at Lian Yu strangely.

"Where's Nongwen?" Lian Yu asked.

"Uh...... I don't know, you're going to ask Uncle Sha. Su Yang said he had no idea.

Lian Yu stared at Su Yang and said, "Hmph, Uncle Sha returned to the military region early in the morning, are you hiding something from me?" ”

Su Yang said helplessly: "Alas...... Okay, okay, I'm afraid of you, but this matter, you'd better ask General Sha to go, it's not that I want to hide it from you, it's just that General Sha said that he wanted to keep it secret. ”

Su Yang then asked curiously, "By the way, what are you looking for Nongwen for?" ”

Lian Yu said, "Didn't he say that day that they had developed a more advanced evolution potion?" I want to ask him if he knows about the formula, for this formula, my dad's hair has been graying a lot lately, and the whole thing doesn't come out in the laboratory, I ...... I don't want him to work so hard. ”

Only then did Su Yang understand what Lian Yu was worried about, so he comforted: "In this way, then I can tell you something, it will get better soon, maybe a more advanced formula has been discovered at this time?" ”

Lian Yuhu looked at Su Yang suspiciously: "Why are you so sure?" ”

Su Yang scratched his head and said, "Anyway, don't worry about it, I can't say more, it's a matter of confidentiality." Anyway, you can rest assured. ”

"Really? You didn't lie to me? "Lian Yu is still a little worried.

Su Yang nodded: "Really! ”

Lian Yu seemed to breathe a sigh of relief, his face returned to his previous smile, and said to Su Yang: "Okay, let's practice again, don't forget about it if you don't move for a few days." ”

Su Yang originally wanted to see how Wang Shou's knife was doing, but he didn't expect to be pulled together by Lian Yu to practice again, so he had no choice but to agree to Lian Yu, and he also happened to be familiar with the control of his body and strength after evolving to the third level.

Unexpectedly, after only ten minutes of practice, Wang Shou came to Su Yang first.

Wang Shou, who was happy, stopped the two who were practicing, and didn't care about sorry in Lian Yu's dissatisfied eyes, and pulled Su Yang away.

Lian Yu, who was full of curiosity, didn't care whether Wang Shou called her or not, and followed behind the two.

When he came to the door of a manned factory, Lian Yu looked at this place curiously. It's said to be a factory, but it's actually just a larger shopping mall, but where I saw people guarding with guns in the base, I felt strange when I practiced rain, where do I need to keep it so secret?

Looking at Lian Yu who was following behind him, Su Yang could only agree to Lian Yu also going in with him.

Lian Yu just went in, his face was full of shock, there were several large machine tools working on the entire first floor, many people were busy with masks, and after seeing Wang Shou and they came in, an uncle who was nearly 50 years old came over with a knife.

Lian Yu saw that the appearance was extremely similar to Su Yang's sword, and he knew that it must be very sharp, but this uncle could actually carry the knife with two hands, which also made Lian Yu think that this uncle was as powerful as Su Yang.

Su Yang looked at Wang Shou in surprise and asked, "It's done?" ”

Wang Shou nodded: "This is the first sample, I will call you when it comes out, and I haven't tried it yet." ”

Su Yang took the knife and danced a few times, the knife seemed to be light to him as if it had no weight, thought about it, handed the knife to Lian Yu and said, "You try." ”

Lian Yu curiously took the knife from Su Yang's hand and checked it, the weight was moderate, suitable for long-term combat, under the guidance of Wang Shou, Lian Yu took the knife and came to a big stone. looked at Su Yang and Wang Shou, and slashed at the stone at the signal of the two.

Since Su Yang took the knife, all the people in the factory have come around, after all, they have been continuously improving and testing new products day and night, whether they are good or not, whether they can be used depends on now.

The stone is more than a meter high and nearly a meter thick, Lian Yu first patted it with his hand, felt the quality of the stone, and then raised the knife high and cut it.

Lian Yu felt like a knife cutting through the water, there was a little resistance, but this did not prevent the knife in his hand from slashing into the stone solidly, cutting out a large crack in the big stone.
