Guo Le said fiercely, "Fuck! Let's test this time to see if the space in the different-dimensional bracelet is still one cubic meter. It should be expanded to 10 cubic meters. Next time, try to arrange as few people as possible to transport supplies. Save whatever you can.

What the hell."

After having a clear price, the Seven Demon Star advance team will be more careful when doing things.

Xiang Xixi and Qiu Feng moved around in Guyan City, which already has a six-meter-high city wall. Guyan City covers a total of nine square kilometers, which is 9 million square meters in total. The area enclosed by the two-way portal with alloy fences is only 700 square kilometers.

More than one square meter, less than one ten thousandth.

The place where the seven female captives were before was just 12 tree saplings planted symbolically. Although there were plant ash to backfill around the tree roots, the water absorbed by the plant ash was limited after all, so these 12 tree saplings were carefully planted by the Phantom Shooter.

With care, it survived, but it never grew well.

Xiang Xixi led Qiu Feng up the unfinished city wall, pointed to the inside of Guyan City, and said, "Idol brother, I plan to plant a ring of cold-resistant and drought-resistant desert plant seedlings a hundred meters away from the city wall, with a thickness of about

50 meters, and the planting spacing is reduced to 2 meters.

Dig down three meters and backfill with sand filled in five layers of paper bags. The lowered water flows directly through the sand layer to the rock layer 20 meters deep underground. Similarly, five layers of paper bags filled with sand are also used to backfill the outside.

To prevent water from flowing downward through our tree planting areas, although five-layer paper bags cannot 100% prevent groundwater loss, they can reduce the rate of groundwater loss to a great extent.

After backfilling five layers of paper bags, remove one meter and then lay 20 centimeters of plant ash, followed by 08 meters of sand, then 50 centimeters of plant ash and 50 centimeters of sand. On top of this, we will plant cold-resistant and drought-resistant plants, even if there is no phantom

With the shooter's careful care, the survival probability of this batch of plants is also very high, as long as we continue to carry fresh water from the Seven Demon Stars."

Qiu Feng said, "You can do the afforestation thing. I don't know much about it. One hundred meters away from the city wall is equivalent to 28 kilometers long on one side and 50 meters thick. In theory, about 140,000 plants are needed.

As for seedlings, we only have more than 4,000 people, and each person needs to plant more than 30 trees on average."

Xiang Xixi smiled bitterly and said, "It's far from enough. Another 100 meters inward will have to be planted with a circular plant belt according to this specification. Transforming the desert area into a livable area is no less difficult than planting trees on the Seven Demon Stars."

Livable renovation.

Of course, with the support of a steady stream of fresh water, the transformation of desert afforestation is relatively less difficult. The most important thing is to provide fresh water in the desert area.

Aren't there four round pits over there? The bottom of the round pit has directly reached the rock layer. The diameter of the bottom is 20 meters and the diameter of the top is 50 meters. They are surrounded by single-layer paper bags, so I plan to make two of them.

In the future, it will be directly backfilled as a vegetable planting area, completely using plant ash mixed with half of the sand to backfill.

After the plants have been slightly planted and have reached a certain scale, the other two connected circular pits are filled directly with water. On the one hand, the water can be used to adjust the temperature difference between day and night in Guyan City. On the other hand, it is also convenient for the formation of underground water in Guyan City because of the city wall.

Watering starts directly from the rock layer and goes up. In addition to a few small holes ten meters underground, there are also several small holes five meters underground and two meters underground. Because Guyan City

It is entirely possible to form its own unique groundwater system in this desert area.

In this case, a single circular pit can store about 130,000 tons of water, and two circular pits can store 260,000 tons of water. We can also raise some fish in the two circular pits, and Guyan City will be able to survive."

Qiu Feng said, "The plan is very good. Let's just play like this. After the round pit is filled with water, we will build the second garrison next to the relay station. You see, Lezi has led his troops back. The current two tube towers are not enough, and we have to

Seize the time and start building again. Those who come now can only go to the circular pit to set up the marching tents first.

But now there are 4,000 people. Even if 10 people make a bonfire, there will be 400 piles of plant ashes in one night. Considering that the Tongzi Tower is not fully established at present, especially on the third floor, you can organize people to dig some round pits first.

Layers of paper bags and sandbags are enough to keep our reservoirs going for a long time. I suggest that we completely re-excavate the reservoirs. A city of 10,000 people only has 260,000 tons of water storage, which is obviously too little. It should be bigger.

"

Xiang Xixi shook his head and jumped off the unfinished city wall with Qiu Feng to greet the new regiment.

Seeing so many new soldiers coming, the first batch of seven female prisoners returned home immediately. Caesar also held the scimitar at his waist tightly, and Qiu Feng returned his weapon to him.

Mu Hong walked directly in front of Qiu Feng and Xiang Xixi and said, "My Air Force General Mu Hong has returned to the team after recovering from his injury. Marshal Guo still has some ties to the Seven Demon Stars, but no one can suppress the advance troops, so I personally led the team here."

"

Qiu Feng nodded and said, "Admiral Mu Hong, hand over the materials and start the station construction work immediately according to the arrangements of Chief of Staff Xiang."

"Yes!" Mu Hong gave a military salute and then turned back to command the army.

Xiang Xixi looked at Qiu Feng and walked directly over to follow Mu Hong.

Qiu Feng was very pleased that Mu Hong could recover from serious injuries. Fortunately, before Guo Le went back, Qiu Feng replenished 100,000 energy coins and entered the two-way portal. Xiang Xixi and Guo Le also replenished 100,000 energy coins each.

After entering the energy coins and returning to the Seven Demons Star, Guo Le added another 300,000 energy coins, otherwise something might happen during the teleportation process.

As the saying goes, there is strength in numbers. With the addition of 4,000 new troops, the construction of Guyan City is changing at a speed visible to the naked eye. First of all, the casting speed of the city wall has doubled. If it were not for the time it takes for the concrete to dry out, I am afraid that these new batches of

The incoming army could cast the city wall in place in one day.

The afforestation army has also started taking action. Qiu Feng no longer dares to use phantom shooters to use life magic to plant trees. The first batch of 40 phantom shooter soldiers have been sick until now in order to plant those four trees.

I can't say that I have completely lost my combat effectiveness due to my languorous appearance, but I'm afraid my combat effectiveness is not even one-tenth of what it was when I was healthy.

More than 20 high-end material warehouses were built at an astonishing speed, and 6 tube buildings were started at the same time. The first floor can basically have 40 rooms on both sides, and one room can accommodate 10 people, so a total of 1 tube building can

There are about 1,200 people living there. Counting the newly started constructions, Guyan City has a total of 10 tube buildings.
Chapter completed!
