What Qiao Yuchen took out was a map of the surrounding area, which included the map of Dawn City, Water Kiln Base, Baxia Base and several cities in the east, and Jin'an, Andu and so on in the west.

Surrounded by mountains in the north, the mountain range used to be the city of Chunan, and the south was surrounded by water, and the waterway used to go straight to the west of Pingyang.

On the map, Qiao Yuchen drew in circles with the red ones, and wrote a lot of things, and Batu and Li Rongchun looked at them carefully.

While the two of them were looking, Qiao Yuchen spoke: "I need to consolidate all the locations according to the map within a week, and clean up this area at the same time, so as not to leave traces of strange beasts and zombies......

The more Batu and Li Rongchun looked at it, the more frightened they became, the range marked by Qiao Yuchen on the map directly included the water kiln base and the dam base, and at the same time, all the roads leading to their three bases were surrounded inside, forming a huge barrel.

Among them, Qiao Yuchen also designed a three-layer defense, that is to say, to reach their three bases, it is necessary to go through three defenses from the periphery to be able to reach.

The two swallowed at the same time, and Batu said: "In a week, can we complete such a big project......

No wonder he hesitated, after all, the defense designed by Qiao Yuchen contained too many things, and it would take a lot of time to build the city walls within a radius of 100 miles from the three bases. It's not something that can be done in a day or two.

Qiao Yuchen smiled and said, "It's man-made, so I need the full names of the people in your base to mobilize, and at the same time recruit people in Huadu to let them join the construction." ”

Batu's brows furrowed slightly, and he asked strangely, "Boss Qiao, why don't you build the flower capital inside?" If we let the people from Huadu come to build for us, will they make a fuss......

Qiao Yuchen pointed to the map and said, "Do you remember the road from Huadu to the base under the dam?" ”

Batu was a little strange, but still said: "Well, remember, there is only one avenue from Huadu to the base under the dam, and the other is a small road......

Batu's eyes lit up as he spoke, and he said, "Oh, I see......"

Li Rongchun on the side was confused, and hurriedly asked, "What do you understand, why didn't I see anything?" ”

Batu laughed, "You can't see normal. ”

Then he pointed to the map, which was between Huadu and the base under the dam, and said: "Between the dam and Huadu, whether it is a big road or a small road, there will be a tunnel, this tunnel is the only way between our two places, in addition to this road, only from the waterway through the city of dawn can enter our range, so our range is the best place to defend......"

Qiao Yuchen smiled and received: "Therefore, I will not include Huadu in the scope of construction, because Huadu is accessible in all directions and is the most difficult direction to defend, of course, I will not let Huadu go." ”

Qiao Yuchen took out a pen and drew it around the flower capital.

With Qiao Yuchen's marking, Batu and Li Rongchun also understood.

"I will make Huadu an outpost, defense will naturally have to be done, but it will not be used as a key defense, once Huadu is breached, it will be evacuated from the tunnel for the defenders to enter the defensive circle of our three cities, and the key to blocking the enemy is ......"

Qiao Yuchen's pen is at the tunnel: "It's here......"

Batu and Li Rongchun both nodded, I have to say that in this way, the security of their three bases will be improved to an extremely high level, even if there are more alien creatures, as long as they still have physical strength, it is extremely difficult to break through this defense.

Looking at the map, the defensive range above is actually very large, outside the Huadu base, in the entire range of the three bases, there are eighteen defensive points alone, these are peripheral defenses, and there are also two or three defensive points between each base inside.

From the periphery to each base, there are also three layers of defense, which can be said to form an iron bucket-like defense.

Batu pondered, he had the biggest question in his heart, the personnel problem.

"Boss Joe, the defense is pretty good, it's just ...... We don't seem to have enough manpower to defend so many places......"

Qiao Yuchen nodded and said, "Well, I have also calculated this, the total number of people in Dawning City is less than five hundred, and the population of the water kiln base is only more than a thousand, and the most is the base under the dam, and the total number of people is not more than two thousand......

Then Qiao Yuchen changed his words and said, "So, I need you to divide the staff into groups of twenty people, stick to each point three times a day, and focus on training and other engineering construction." ”

"Other ......" Li Rongchun was a little speechless for a while.

Batu was also curious, judging from Qiao Yuchen's words, this time it was really a big move.

"Well, after the defense is done, I will connect both of your cities to electricity and water, this project alone will not be so easy to do. At the same time, each defensive point needs to transport ammunition, all kinds of materials, and the transportation problem also needs to be solved......"

Hearing that electricity can be connected, Batu and Li Rongchun are very excited, in fact, it is better to say something about electricity, after all, there are circuits between each city, and only need to connect these circuits, and it will be a little troublesome on the water, and at present, Qiao Yuchen only has one purification machine here, and if you want to connect, you need to relay the pipes.

Water used to be used to bring back some drinking water, but after the establishment of Dawn, both bases were transported back and forth by water trucks, and once the pipes were laid, they no longer needed to waste humans transporting water.

As for why the people from the three cities gathered in the Dawn City, Qiao Yuchen also considered this, and he didn't know what kind of changes would happen in the future, so he still decided to keep the two cities as a backup, so he had the intention of doing this defense.

Qiao Yuchen thought very carefully, under the current resources, he can only do this in defense, and if he wants to consolidate it, then I am afraid that something new will appear in the system.

Batu and Li Rongchun, after looking at the map, only understood why Qiao Yuchen had this question, if the two of them answered in another way, I am afraid that Qiao Yuchen would discard this defensive plan. After all, it is much easier to fortify one city than it is to fortify three.

"You all already know the plan, and as for some other arrangements in the future, we will have to wait for the completion of the most preliminary construction."

Qiao Yuchen folded the map and put it on the side of the table, and then he spoke: "In addition to this plan, I still need you to go back and do one thing......
