Chen Zhengjie now goes to the books when he is bored, and finds out something useful for living on the garbage star, but the materials are too scarce, and he doesn't want to always report to the leader what materials he needs and what things to build.

Usually in his own metal nest with all kinds of light brains for various types of maintenance, as well as research, although it is almost impossible to produce such a high-tech thing as a light brain on this garbage star, but learning a little more is a little bit, so Chen Zhengjie did not leave any knowledge on the light brain, but when facing various types of light brains, you can basically check once or twice to fully understand where the fault is.

Now many soldiers in charge of patrolling often drive empty boats to patrol gang territory, and the air boats are assisted by light brains, and those old light brains often have various problems, so now the leader directly lets those armed personnel have problems with the airships of the armed personnel and drive them directly to Chen Zhengjie for repair and maintenance.

It can be said that the previous patrol airboat basically had a 35% attendance rate, which is already thankful, and now with Chen Zhengjie, the airboat that can be on duty has reached 67%, which means that the gang's territory will not be maliciously occupied by others, coupled with the motorcycle he invented, now the gang has a vague intention to expand the territory, but the leader's development route is the wild land around the gang, since the number of empty boats and motorcycles is basically no problem now, so there is almost no big problem with controlling some wild land, The biggest concern is what the other surrounding gangs will think.

The leader sent people to a few gangs around to discuss the issue of forming an alliance, after all, now with the more and more frequent storms of perseverance, the survival of scavengers and wanderers is becoming more and more problematic, and the number of people thinks that there is a negative growth, let alone escaping from the garbage star in the long run, I am afraid that even the operators on the spaceship may not be complete, so the leader means that he provides tools such as motorcycles and their airboats to help repair after problems, etc., and then it is the form of a small alliance, and everyone advances and retreats together.

"Dudu ......" in the middle of the night a burst of sirens sounded suddenly, this alarm sound represents the sound of the beast tide, the beasts outside the fence will impact the size of the human survival base in a specific period, such a beast tide will bring great disasters, so each gang base will be equipped with sentinels, specifically to observe the dynamics of the beasts, in case of observing the beasts have gathered, the alarm must be sounded, so that the scavengers and wanderers in the base have time to rush to the place to avoid the beast tide.

This time it was also the discovery of the beast tide, Chen Zhengjie in the past would often be scared when he heard this kind of alarm, after all, he was small, short arms and short legs could not run fast, and he was often crowded by the crowd like fritters, and if he was unlucky, he would be squeezed to wrestle, and he would accidentally become the hero of the stampede, but now it's okay, the place where he basically lives is already in the middle of the gang, and this place basically doesn't have to be afraid of the invasion of the beast tide.

The armed men in the gang have brought all kinds of lasers to climb the defensive wall with particle weapons, and accurately kill the large beasts that have the ability to impact the defensive wall, and the mutated beasts basically have no resistance in the face of such weapons, don't look at their ferocity in the face of bare-handed humans, but in the face of these weapons is basically a matter of light beams, and after the first pass, it basically becomes a food for scavengers and wanderers.

Everyone was solemn, the women and children were arranged in the safest place, the elderly were slightly more periphery, and the young men who had weapons used weapons, and those who did not have weapons used their own polished metal spears to defend against those who slipped through the net, which was also a normal mode of defense. After all, there will be more or less some beasts breaking through the defensive wall, and at that time, it will be up to these scavengers and wanderers to intercept them, otherwise if the soldiers on the defensive wall turn around and kill, it will be equivalent to a gap in the defensive front here, and what awaits them is undoubtedly the most dangerous thing.

Chen Zhengjie was not to be outdone and picked up the metal crossbow he made a while ago to do the defense work in the base, this kind of strong crossbow has been made in batches, basically all the armed personnel are standard one by one, the number of crossbow arrows depends on what task they perform, now they can not use the weapon without using it, after all, the loss of weapons on the garbage star cannot be compensated, All Chen Zhengjie made a strong crossbow and just let the gang personnel use this kind of simple lethality but only a little weaker cold weapon is also a very good choice, the only drawback is that the time to load the crossbow arrow is relatively long, now Chen Zhengjie is studying the arrow magazine, and when this problem is solved, it is basically not much worse than the firearm.

The hand finally appeared, even in the case of poor light at night, you can see the dust in the distance from far and near, this is a huge number of beasts together to step on the dust, as well as obvious traces of shaking, it is not difficult to imagine, this time the scale is a bit large, the leader after reading the information let the airboat carry the bomb first, incendiary bombs for the first wave of strikes, otherwise let these beasts hit the defensive wall is estimated to be unable to withstand it soon.

The airship went to the location of the beast tide at a fast speed, all kinds of bombs were dumped into the beast herd like money, and the bursts of fire in the distance announced that a large wave of beasts had been wiped out, but the current situation is still not optimistic, this time the scale of the beast tide is much larger than before, at this time it would be better if there were more airships?

The airboat quickly came back to load the bomb, and the colleague reported to the leader about the approximate size of the beast tide, this news made the leader not calm, this time the beast tide was 70% larger than the largest one encountered before, recalling the last beast tide, the base was almost trampled on and abandoned, and the scavengers and wanderers died a lot, Chen Zhengjie's grandfather was trampled to death during the beast tide.

It seems that the engine armor group is going to be released, otherwise it is estimated that the base will be attacked by these beasts again, and then the leader let people announce the situation of the beast tide this time, I have to say, in the face of such a beast tide, it takes the concerted efforts of everyone in the entire base to be able to resist it.

With the announcement, more than half of the young men came to the defensive wall as a supplement, and the spear-wielding men were placed in the gaps between the armed men, which would also alleviate the shortcomings of the lack of manpower.
