After three days, the rain continued, Tang Yizhou felt that he was about to get moldy, especially the feeling of huddling in a small tent.

Fortunately, he is not alone. Zhang Xin is not only a good girl, but also beyond his expectations of strength and optimism, just like a ray of morning sunshine shining on his heart...

So when the rain finally stopped, Tang Yizhou was still a little unfulfilled.

It was the morning of the fourth day. The dark clouds had dissipated last night. The golden sunlight shot down without warning. The world that had been covered with dust for a long time instantly became energetic and full of vitality.

Even the despair in my heart seemed to be a little diluted.

After walking out of the tent and taking a deep breath of fresh air that was slightly cold, Tang Yizhou instantly became a person, throwing away all the warm scenes of the past three days. Now, the two of them have to work hard to survive.

"There are still 100 units left, I'm seven and you three. Today we have three tasks. One is to try to replenish the power as much as possible. The second is to make your miniature crossbow launcher. The third is to wait until the night, when the soil is no longer muddy, we have to dig a few lurking pits nearby to make temporary camps. This rain has made many mechanical monsters quiet in these two days. We have to take advantage of this opportunity to develop well."

After Tang Yizhou finished speaking, Zhang Xin nodded vigorously, her eyes were very strong, and the world was so bad that there was no need to be any weakness.

No need to say anything else, the two of them worked together to transfer the trolley to the highway, first spread out the rainproof tarpaulin, so that the thing must be dried to prevent mold.

Then all the energy storage wings were moved out, and the electricity inside was divided into half, and then they were placed on the shoulders on both sides of the highway, and some weeds and leaves were used as decorations.

"Sister Zhang, take advantage of the time now, you can find a place to test the No. 2 crossbow and No. 3 crossbow several times. If you have any minor problems, you can adjust it."

Tang Yizhou smiled and said that the rain passed by the sun, which not only brought the weather advantages, but also meant that the development of their small team had officially entered the fast lane.

Zhang Xin now has the power of four people, and can easily use crossbow No. 2 and crossbow No. 3. Combined with her talent in archery, she can fully achieve an arrow within a hundred meters.

This is the best sniper and the most advantageous cover.

When it rained two days ago, Tang Yizhou used mechanical spider silk to replace the original leather crossbow string. This is really a good thing. It is not only tough enough, but also slightly elastic. The most important thing is that it is not afraid of rain, which perfectly solves the disadvantages of fighting on rainy days.

There were many mechanical spider silk bundles, almost more than a thousand. Only 200 crossbows No. 2 and No. 3 crossbows were used. The rest were carefully stored by Tang Yizhou. Next, they could be used by making No. 4 crossbows.

So now he handed over both the second and third crossbows to Zhang Xin, one with a leader-level heavy arrow and the other with a leader-level light arrow.

Heavy arrows are used to shoot large targets and have extremely strong armor-piercing capabilities. Even if they are leader-level mechanical monsters, they can be killed in one blow.

Light arrows are used to shoot more flexible targets, such as mechanical birds in the air. This is mainly because of fast firing speed and accurate.

Next, Zhang Xin found a good position and Tang Yizhou set a target. The shooting distance of heavy arrows is 80 meters, and the shooting distance of light arrows is tentatively 120 meters.

To be honest, Tang Yizhou will never try these two people, so Zhang Xin is different.

The first test shot of heavy arrow actually left the target.

Tang Yizhou was not surprised but happy.

"This is a good thing, which shows that the ejection balance ability of mechanical spider silk is much better than that of leather crossbow strings, so the ballistic has changed."

In the second test shot, Zhang Xin readjusted the ballistics and hit it successfully. Only then did she breathe a sigh of relief.

"It would be great if there was a scope. It was more than 100 meters. I had to aim for a long time. Also, this mountain needs to be remade and the position needs to be adjusted. In short, the biggest problem with these two crossbows is that the standards are too rough... Well, I have no other meaning, Boss Xiao Tang."

Zhang Xin was already much more confident and even made a joke about Tang Yizhou.

"If I were the boss, then what are you, Sister Zhang, Secretary Xiao Zhang?"

"……Hate!"

——

After helping Zhang Xin test shoot, Tang Yizhou asked her to continue practicing archery, or to be more precise, to be familiar with the strange ballistics of crossbow No. 2 and crossbow No. 3.

For the time being, it is impossible to improve the accuracy standards of these two crossbows, and they can only rely on a little practice.

As for Tang Yizhou himself, he was not in a hurry to work. Instead, he walked around and became familiar with the environment. Then he started to use clay to make molds while basking in the sun.

This time he will make a lot of molds.

First, it is the mold needed for crossbow No. 4. Because all the materials are available, mechanical spider silk can be used for crossbow strings, crossbow machines use the hardest leader-level wild dog steel, and crossbow arms that require elasticity and toughness are used for crossbows.

This was discovered by him using the metal detection skill. Both the leader-grade steel are 15 times harder than ordinary steel, while the toughness of spider steel is 16 times that of bow boards.

The second type of mold is the miniature crossbow launcher, which also requires wild dog steel.

As for the last mold, it is naturally energy storage wings. Tang Yizhou really plans to build one hundred pairs.

Of course, in his spare time, he also had to cut out the last four magnetic blade grenades, but this was really not a difficult task for him who had mastered ordinary polishing skills. All he lacked was power.

Now the power supply has become the biggest bottleneck restricting the development of Tang Yizhou.

However, this kind of thing is unhurried. He only has one or two hours of work this day, and the rest is used to bask in the sun and convert electricity.

After accumulating enough power, I quickly processed the workpiece, but in less than ten minutes, the power was exhausted.

This embarrassment is hard to describe.

Fortunately, this area is very quiet, the mechanical wild dog group was killed, the mechanical spider group was severely injured, and the mechanical ape was killed again, which is so comfortable.

As long as it doesn’t rain, every day is a paradise for Tang Yizhou.

In this way, he was responsible for processing and converting electricity to sunbathing, and Zhang Xin was responsible for alerting and practicing archery, one day, two days, three or four days.

The two of them did it at sunrise and returned at sunset, and they really had the illusion of a doomsday paradise.

During these four days, I don’t know how much Zhang Xin’s archery skills have improved, but Tang Yizhou created a No. 4 crossbow, a miniature crossbow launcher, four magnetic blade grenades, eight energy-saving wings, and 100 standard crossbow arrows for miniature crossbow launchers. Even the various mechanical components required by the mechanical crow were built in advance, and they could be assembled and activated as long as conditions permit.

In short, this wave of development is quite successful. Coupled with the mechanical tower shield, the overall strength of the two of them has increased by at least several times.

However, Tang Yizhou still had no intention of wandering, and he had to continue to develop until all the resources at hand were converted into survival cards.
