The midday breeze blew across the meadows, in a world where the earth was all covered with a layer of grass green.

A city entrenched under a high mountain plain, surrounded by high walls, between heaven and earth, the verdant intersect with the dusk of the sky, which should represent the green of life, but here it is more of a dead silence and desolation.

When life becomes monotonous and lonely, isn't that all that remains is dead silence and desolation?

Between heaven and earth, only those lonely weeds can be seen growing unusually densely, and among the green blades of grass, they have become rich to some blue and black.

This is a sign of nutrient sufficiency, and the virus in the air has become the most abundant catalyst for the growth of these weeds.

Nowadays, weeds, which are generally more than a meter long, continue to grow wildly, and perhaps the whole world will soon be covered by these weeds, leaving only those lonely steel forests, and in a few years, even steel forests will be covered and replaced by grass green.

If it weren't for the herbicides being cleaned up every day, the weeds in the base would have covered every place.

But around the besieged city of Erbil, weeds still flourish.

If human beings had been able to have this kind of grass green with super tenacious vitality when human beings were there, perhaps the greening of the earth would not be a problem.

These weeds, in particular, not only absorb viruses from the air to grow, but they also absorb all the gases in the air except oxygen, which are then converted into highly pure oxygen.

I've never seen how these weeds, which look like pasture, appeared.

At least, for the current environment of the planet. The appearance of these weeds. Maybe not a bad thing.

If it weren't for the fact that these weeds carry viruses themselves. Cai Ruichen even thought about transplanting these weeds into the present world, after all, the Middle East world needs such green too much.

Cai Ruichen, who was standing on the wall, couldn't help but think in his heart when he looked at Erbil, which was almost surrounded by weeds.

Perhaps, when scientists appear, they will be able to solve the toxins in these weeds and transplant them to the present world!

And on the wall at this time, I am afraid that he is the only one who has such an interest in thinking about such distant things.

The main force of the 2nd Brigade of the Red Guard Corps. They all came to the city walls, but the troops of only 5,000 men looked so small in the face of the walls surrounding the city.

Under the walls, a large box of ammunition boxes was transported up by elevators, and each wall had an elevator to transport personnel, weapons and ammunition.

Otherwise, the 20-meter-high wall, the entry and exit of personnel and the supply of ammunition will also be a trouble. Not to mention that they are now forty meters high.

If only it were really necessary. Cai Ruichen wants to build a 100-meter-high wall with five layers of walls.

Even he wanted to thicken the wall, forty meters wide and a hundred meters high. It is even possible to put down the production line of a primary arsenal on it and produce weapons and ammunition directly on the fence.

For the base wall, such a building is not just Cai Ruichen's utopia.

It's nothing more than the time and money that needs to be consumed, and as for the construction side, even labor is not needed.

Because as long as the walls are combined, they can fit together perfectly and become a whole.

If it were built like this, it would not be a wall, but a fortress.

However, for the safety of the base, Cai Ruichen really plans to do this.

Once Erbil has been successfully recaptured and all areas within a radius of forty kilometers around the base are under control, the construction of such a fortress can begin.

However, it is estimated that it will take a year or two to complete the huge project alone.

So, now it's just talking.

The ammunition boxes that had been transported in large quantities were opened one after another on the fence, and various anti-infantry mines were neatly placed inside.

There are also a large number of broadsword mines, which are used to kill and injure infantry, and the power is absolutely powerful.

Behind the fence, heavy trucks were still transporting these ammunition boxes, and the soldiers driving forklifts below were also busy transporting.

This time, Cai Ruichen made a bloody investment and produced 200,000 mines of various kinds in one go.

And these mines all have one thing in common, that is, they are very lethal against infantry.

When all the 200,000 mines were transported to the fence, the rocket minelaying trucks that were ready also drove into the elevator.

The next thing is to lay mines, Cai Ruichen did not send soldiers to lay mines outside the wall, because no one knows if the mutants inside will escape.

So all of them use rocket minelayers to lay out these mines, and for those mutants, they can't tell what these mines are.

And a meter-high weed, even in the face of an experienced enemy, so many mines are enough for the other party to drink a pot.

And this is only the first wave of mines, and there will be a second batch of mines planted in the wall, after all, if it is really as understood by mutants, then no one knows from what direction they will attack the wall.

Of the walls around Erbil, except for the western wall, which is the direction of the base, the rest of the place is wasteland.

And on the periphery of this wasteland, there is no obstruction, but on the western wall, there is a second sixty-meter-high wall.

In order to recover Erbil, Cai Ruichen was also fully prepared and took almost everything into account.

Compared with the last time in Mozabi County, now behind him, there is a relatively complete team of Red Police staff to help him perfect various details.

Cai Ruichen will even hand over the defense construction work to them to formulate, he only needs to look at it, and after no problems are found, he only needs to be responsible for the construction.

It's like the current mine tactics were proposed by Elleyesel, and there is nothing to say about dealing with those mutants, and the first-level mutants.

The most common bullets can kill them, but they can't hold up a large number, so these mines are designed to kill and injure those low-level mutants.

Moreover, these mines are all professional safety mines, and the mine activation is controlled wirelessly by the base, so there is no need to manually pull the safety open.

It only needs to be put in place, and once the base has activated the insurance, these mines can be used.

Once the mines are not needed, the base can also quickly turn off the insurances and locate the mines, so that the soldiers can quickly recover the dangerous goods.

Of course, these mines can also be planted by hand, and they are no different from ordinary mines.

The biggest feature of the mines produced by the base is that they are very powerful, and their technical performance is also very advanced, and they have a variety of induction explosion methods. (To be continued.) )
