He remembered that the system used to say that it was safe to stay in the shelter, and the higher the level of the shelter, the stronger the defense.

However, the area of the shelter is limited, and now it has been upgraded to the third level of the shelter, which is only more than 100 square meters, and a perfect shelter needs to be built in bedrooms, living rooms, kitchens, studios, and warehouses and other related aspects.

He can cut down trees to build these, but safety is not necessarily guaranteed, because these are built outside of the shelter, which means that the only shelter that the system recognizes is a cabin.

Once the green aperture is gone, then only the cabin is safe because it is built by the system.

But through the system, he created a fence, as long as the building enclosed by the wall is safe.

That is, he can build buildings within the walls at will, and these are all safe.

The larger the extent of the wall, the greater his shelter.

This is a bug in the system.

Looking at the hundred-square-meter wall built in front of him, the corners of Xu Shiying's mouth rose slightly.

With the addition of the fence, he now means that it is safe to have more than 200 square meters of soil.

No matter how dangerous it was outside, as long as he stayed inside the walls, he was safe.

It's a pity that the wall is the largest, only a hundred square meters, and it would be better if it was bigger than that.

Thinking that a radius of 500 kilometers is his territory, then his life is simply not too happy.

However, the wall is only two meters high, which is still a bit low, and if there is a beast with amazing jumping power, it can jump in with a single leap.

In that case, it would still be dangerous for him to stay in the yard.

Xu Shiying thought about it and pondered how to reasonably increase the safety factor of the wall.

Suddenly, he had a flash of inspiration and thought of something.

And Bai Zhong had it, so Xu Shiying contacted Bai Zhong and asked him if he had any bamboo seeds.

That's what he came up with, as long as he planted a row of bamboos outside the wall, the bamboo could grow very tall and form a natural barrier.

It didn't take long for Bai Zhong to reply and ask him how much.

Xu Shiying said: "How much, how much, and I'm in a hurry to plant, fast!" ”

He had to plant it all before the green circle disappeared, and it would be dangerous if he was too late.

So, he was in a hurry.

There is bamboo not far from the Baizhong Shelter, and bamboo grows very quickly, and it can be planted as long as it is not salt land, which is not a rare thing.

Bai Zhong saw Xu Shiying's information and thought about it, and at present, there are only a hundred bamboo seeds in his hand.

Since Xu Shiying asked for it, Bai Zhong naturally sent all the hundred bamboo seeds in his hand very happily, but he didn't ask for the snake meat that Xu Shiying traded.

He was able to join the alliance, Xu Shiying did not contribute less, he has lived for most of his life, how can he not see this?

If it weren't for Xu Shiying's more anxious want, give him enough time, let alone a hundred, a thousand can be given to him.

After receiving the bamboo seeds sent by Bai Zhong, Xu Shiying did not plant them immediately, but looked at the open space inside the wall and fell into deep thought.

Originally, there was no wall, everything was planted wherever he wanted, and there was no reasonable planning at all, which led to a very chaotic planting.

Now that there is a wall, such a large open space, it is natural to plan carefully, and now that it is dark, out of the wall, he doesn't know if it will be safe.

The area of the green aperture has certainly expanded, but he has no idea how much it has expanded.

The Guardian Rattan has just been planted, and if it is dug up and replanted now, it will affect the growth of the Guardian Rattan.

Xu Shiying walked around the fence and thought about it, since bamboo seeds can be planted outside, then a wave can also be planted inside the wall.

The bamboo should be combined inside and outside, which can play a more defensive role.

It's that bamboo attracts insects and birds, which is a problem.

But he doesn't care about these things now, and he will solve the problem in front of him first.

"Squeak!"

When Xu Shiying was thinking about how to plant bamboo, Xiao Qi's cry came from the house, it seemed that the snake meat should be cooked, and Xiao Qi was reminding him.

Xu Shiying clapped his hands, knocked off the soil on his hands, got up and returned to the house, brought out the mud bowl from the fireplace, and smelled the meat in the bowl, Xiao Qi was excited.

Jumping around non-stop.

"Don't worry, it's still hot, I'll eat it later."

Xu Shiying put the mud bowl on the ground, the little guy wanted to pounce on it, but was stopped by Xu Shiying, although he was in a hurry, but Xiao Qi knew that Xu Shiying was for its good, it just had to go to the fireplace, hold a piece of wood, as a teething stick, to relieve the anxiety in his heart.

"This kid should really change his name to Glutton."

Looking at Xiao Qi's actions, Xu Shiying bit his head helplessly.

I've never seen anyone so gluttonous.

Firewood was added to the fireplace and the kang bed, and the temperature in the room instantly rose to more than 20 degrees, making him sweat.

Xu Shiying took off the fur sweater on his body and changed into a T-sleeved down jacket made by Bai Zhong.

The cotton stuffed inside is just right, very warm, but a little thinner than a fur sweater, but Bai Zhong obviously thought of this when making clothes, and he deliberately left a ball of thread on his left shoulder.

That ball of thread will open with a slight pull.

And this place is used to hold cotton, which can be added or taken out with the temperature, which can be described as comprehensive.

Putting on a T-sleeved down jacket, Xu Shiying walked out.

The planning inside the walls is not yet complete.

It's still early, and the upgrade package will only come at 8 p.m., which is three hours before 8 p.m., which is enough time.

Walking out of the room and into the wall, he had no ruler, so he could only use the distance between his feet to measure how the bamboo was planted.

If you are too close to the wall, the roots of the bamboo will have a certain effect on the wall, and if it is too long, the wall will be crooked or tilted.

I measured it under my feet, and I felt that it was seventy centimeters away from the wall, which should be enough.

Xu Shiying took a memory metal shovel, dug a hole, put a bamboo seed into the dug soil pit, and covered the soil.

Then measure the distance of one meter with your foot and start planting the second one.

According to the measured distance of one meter, Xu Shiying continued to plant, and half an hour later, when all the seeds in his hand were planted, Xu Shiying's face showed a bright smile.

With the presence of these bamboos, his heart was a little more steady.

However, a hundred planting trees could only barely fill the inside of the wall, and as for the outside of the wall, he still needed to buy seeds from Bai Zhong.

It's just that with the bamboo seeds inside the wall, there is no hurry outside the wall now.

The next step is to plan how the vacant land within the fence will be used.

He picked up a wooden stick on the ground and divided the area according to the composition in his mind, where is the warehouse, where is the kitchen, where is the vegetable garden, and where is the bathroom.

The wooden stick simply drew the distinguishing line, and Xu Shiying pondered that he must build a fence with ready-made bamboo poles, otherwise, once it rains, these traces will disappear, in that case, what he did today is tantamount to doing it in vain.

took out the "Survival Manual" and contacted Bai Zhong again, like he bought a lot of bamboo, Bai Zhong didn't want his things, and then Xu Shiying told him that if he didn't accept it, then he wouldn't buy his things anymore.

Bai Zhong had no choice but to accept the snake meat sent by Xu Shiying.
