Build a moat? This is really a crazy idea. Except in ancient costume TV dramas such as the romance of the Three Kingdoms, this kind of thing is rarely seen in reality.

But Zhao Zixuan explained the benefits of this facility.

"First of all, if we build a moat, we can divert the water source of the dragon river and completely block it from the upstream to prevent some zombies or mutant animals from entering the city through the water source."

"Second, the moat surrounds the city for a week, which is almost equivalent to a natural defense circle. If those zombies want to enter our side and really attack us, they must cross the moat. I don't know how many zombies will be washed away by the river."

"Third, it can also avoid the disaster of flood. At this time, the weather is very abnormal. In case of rainstorm and flood, the Longhe River will flood and destroy the farmland in the middle of our city, which is very bad. And the moat can play a good diversion effect and avoid the city from being flooded."

Zhao Zixuan said several benefits in a row.

"Moreover, the area around the moat will become a wet place like a swamp. Those places can also be used to grow rice, which is equivalent to developing an additional field."

In that case, the moat really has many advantages, but the amount of work for this task will be very huge.

The whole process, which takes time, manpower and material resources, may reach an astonishing level.

"It may take a lot of time," ah Shen mused.

"Are we short of time?" I smiled.

Yes, we don't lack time now.

Time is nothing to us at all.

So many people place their hopes on us, so we have the obligation and responsibility to provide a safe environment for those people.

Isn't our time just to live?

We have been living in a muddle for too long. Maybe this time is a beginning, which means that we leave the ground and reopen the era of mankind. S city is our first stronghold. We will take this stronghold as the center and spread our radiation area.

"The revision and expansion of the underground city, the reconstruction of s city and the construction of the moat are carried out at the same time. We should clean up the middle as soon as possible, and the problem of food must be solved as soon as possible." after discussion, I said.

"In addition, the Arsenal must resume production as soon as possible. Even for ordinary people, we must ensure that at least one person has a weapon and enough bullets."

"As for the reconstruction of s city and the construction of moat, we may need some excavators and other things. We will look for these things in the nearby cities, and then transport them. Go back and ask if there are any graduates of Lanxiang among us."

This is the advantage of our members. No matter what it is, we will make a decision in the shortest time. Once we make a decision, we will act immediately. We will never be fussy.

"Mumu, go with Zixuan to see how the moat should be built."

"God, let's go out and look for large equipment such as excavators."

"What about us?" the little yellow book said, pointing to his nose. It was a group of main fighting members.

Xu Yang and ye Xuan are also here. They are all young people. Although they have only been here for a short time, they have a very good relationship with Xiao Huang Shu. They get together all day.

"If you want to help in S City, you can also go to the quarrying team. If you really don't want to go there, you can also go around to hunt powerful zombies. Maybe you can get some ability crystal cores and other things." I said with a smile.

These main fighting members actually want them to have a rest. After all, many people have not recovered after several wars, but these people are obviously not the kind of guys who can stand it.

Nothing to do, no fighting, it hurts for them.

This is a very long time. Everyone is in full swing and full of energy.

In fact, many people can think of Zhao Zixuan's ideas, but they are definitely not as complete as she thought. All aspects have been taken into account.

Our large area has now entered a hot state, and everyone is striving for their new home.

Several nearby hills have been blasted flat. All the large and small stones have been cut into neat shapes and transported back. These stones will become our first protective net here.

At the same time, the ruins in s city are also being quickly emptied. In the central area of the city, the cement asphalt ground and various pipelines buried deep in the ground are also cleaned up until the arable soil below is exposed.

Food is the most important. These soils are not fertile enough. They even go to the Longhe River and dig countless silt. Those silt are very fertile and the seeds fall down quickly.

Under the control of Xiyi, those seeds took root and germinated, and the whole process was almost shortened by more than half.

It can be said that Xiyi is the granary of all of us. Without Xiyi, we really don't know how to feed so many people.

About the past month, the expansion of the underground city has been completed, and most members have moved to the underground.

At the same time, the surrounding of the underground city is also being reinforced. The original double-layer glass is now reinforced to the fourth floor. At the periphery of the glass, a defense belt made of stones with a thickness of more than ten meters is added, which wraps the whole underground city like zongzi without leaving any omission.

Now, it's impossible for that bastard of the netherworld to attack us from under the ground.

As for the reconstruction work on the ground, it is also quite smooth. Not to mention, several of us graduated from Lanxiang.

We also got some big guys. With those heavy machinery, the progress speed was significantly accelerated. All the surrounding ruins were cleared, and then the houses were rebuilt. Although there are not many people, we believe that in the future, these houses will be filled with human beings.

Unfortunately, the nearby mountains were destroyed and blasted. The stones were transported around s city. Around s City, a huge great wall with a width of about 10 meters and a height of nearly 20 meters was also stacked. This wall can intercept most zombies outside.

The establishment of the moat was also very smooth. Starting from the place 100 meters above the entrance of S City, we dug the dragon river from both sides and drained the water towards both sides, forming two water areas more than 200 meters wide. The dragon river was completely drained around s City, forming a huge moat blockade zone.

Those zombies who want to pass through this area must pay a very heavy price.

The city wall, moat and the whole s city are now as solid as gold.

At the same time, there is only a little water left from the Longhe River to the internal water source of S City, which is used for the daily life of members of s city.

In addition, on those walls, we installed a camera at intervals to monitor what happened around us.

When all this is done, two months have passed. For such a long time, we have been working hard to rebuild s city.

Now it seems that the effect is very good. There are four bridges around s City, which is the only channel from the ground to s city.

At the same time, Ronaldinho has also manufactured several energy converters, which are distributed in various areas on the surface of s city. These energy converters will not be turned on at ordinary times. This power will be used only when s city encounters an extremely serious threat.

Arsenal also resumed production a month ago!

The arsenal is still in the charge of Ronaldinho, mainly producing bullets! There are no other machine tools here, so we can't produce some heavy weapons.

Finally, old man Chutian gave us support. A set of machine tools for producing shoulder mounted portable missile launchers and shells were transported from a large transport plane. Only then can we be able to produce these things.

Now, the whole s city has taken on a completely new look.
