When the wooden frames were assembled, for fear that these wooden frames would fall apart when they went down to the cellar or over time, Xu Yi not only brushed a layer of white latex on the tenons, but also took an electric drill to drill a few small holes on the side of each socket and nailed them into the split bamboo strips.

In this way, unless the tenons are broken, the wooden frame will never deform or loosen.

Not surprisingly, the wooden frame after processing is unusually reliable, although there are no metal fixings such as iron horns, but it is also stable, Xu Yi tried, even if he tried his best, he could not deform the wooden frame and loosen it in the slightest.

The grooves in the cellar just stuck to the columns on either side of the wooden frame, and the two legs at the bottom were firmly inserted into the pit below. When the crossbar at the bottom of the frame pressed against the groove in the ground, the "frame ears" on both sides also happened to be on the step at the top of the side wall, which was almost a foot wide.

This design allows the pressure from the top to the bottom of the cellar to be evenly distributed by the four walls of the cellar and the entire frame after the cellar is covered. Xu Yi is fully convinced that after the cellar is completed, even if a heavy truck passes by it, it may not be able to crush the cellar buried deep underground.

Xu Yi went down to the cellar to carefully adjust the position of each wooden frame, and only after the last time did he bury all the column corners into the soil and fill in the gaps in the ground, Xu Yi stepped on the ladder and climbed up, ready to complete the capping work.

At the top, Xu Yi was ready to use those thick bamboo poles to lay it.

There are almost a hundred of those Nanzhu bamboos cut down, but in addition to the possibility of using some shade nets to build tea gardens in the future, Xu Yi can't think of any other place to use this, so he simply uses them to build the roof of the cellar.

Calculated a little. It was found that at least eighty or ninety bamboos were used. I'm afraid that the rest of the net is not enough to build a shade net.

But Xu Yi didn't care. Now those tea trees are still small, I can't say how long it will take to use them, even if they do, that bamboo forest can now cut down some new bamboo, so let's get this one done first.

The thickness of the two ends of the bamboo pole is different, so Xu Yi cut off the thinner end of the bamboo pole, and then placed the bamboo pole in front and back, and spread it on the top of the wooden frame.

Although when the one-meter-thick soil on top of the cellar is backfilled, the bamboo poles will be firmly pressed against the beams. It is unlikely that it will be misplaced, but Xu Yi still carefully cut a few bamboo poles and tied the bamboo poles arranged with iron wire into a simple bamboo row to avoid these problems.

Of course, even if the bamboo row is covered, it cannot be directly covered with soil on the bamboo row, so it is difficult to ensure that there will be no broken soil leaking into the cellar due to vibration and other reasons.

Xu Yi went to pick up the rest of the corn stalks, spread them all on the bamboo rafts, evenly spread more than an inch thick, and then began to take soil from the surrounding mounds and throw them on the corn stalks.

It's a lot faster than digging a cellar. It only took Xu Yi more than half an hour to restore the pit to a full size. Xu Yi remembered one thing. He stopped, drank a glass of water, sat down next to him and rested.

Not surprisingly, it didn't take long for Xu Yi to notice that the surrounding mound and the top of the cellar were slowly but continuously changing. It didn't stop until the whole ground, whether it was a mound or a cellar, and the craters of various depths had disappeared.

Xu Yi was also curious, there were dozens of cubic meters of soil dug out of this cellar, where did all that soil go?

Obviously, this answer is only known to the ghost, Xu Yi shrugged, picked up the shovel and prepared to complete the final work.

The whole ground is flat, and even stepping on it, Xu Yi can't tell what is different between the land that has just been backfilled and the surrounding land. If it weren't for a horizontal log on the ground next to him that was slightly higher than the ground marking the outermost position of the cellar, Xu Yi would not have been able to find the location of the cellar at all.

Xu Yi dug directly into the middle of the wood to the outside. Digging through the depth of the beams, what is revealed below is a series of bamboo pipes that are closely arranged vertically, like a wall, separating the underground.

These bamboo pipes were inlaid by Xu Yi with mortise and tenon joints between the horizontal wood on the surface and the horizontal wood on the top of the cellar, so as to prevent the soil on the side from collapsing and falling at the exit of the cellar for some reason.

Then, Xu Yi carefully expanded the excavation to the left and right sides, until it was about two meters wide, and the two columns connected to the horizontal logs on the left and right sides were exposed before stopping, and drawing a rectangle outward along the inside of the columns.

This is the exit of the cellar, and Xu Yi plans to make it a sloping ramp like an underground parking lot, so as to avoid the trouble of going up and down from the top of the cellar. Speaking of which, it really takes a lot of effort to go up and down from the top of the cellar with such a deep cellar!

Of course, this ramp is not used for walking, so it is okay to have a slightly larger angle, as long as you can ensure that you don't slip and fall on your shoulders. Later, the ramp can be built into a stepped shape, so that it will be easier to get in and out of the cellar.

The amount of earthwork was not much, Xu Yi quickly excavated and sorted out the ramp, and the entrance to the cellar inside was also completely exposed.

Xu Yi entered the cellar, and with the faint light from the cellar opening, he shoveled out the broken soil on the ground, and the cellar was completely completed!

Looking around, Xu Yi was very satisfied, this cellar is definitely big enough, at least for a long time in the future, he doesn't have to worry about the lack of storage space.

Just wait for when you will give birth to a batch of logs, dry and find a way to dissolve them into wooden boards, and then decorate the cellar, whether it is the four walls or the ceiling floor, you can completely use solid wood planks to decorate.

Add a door in the middle of the doorpost, and this is a bomb shelter-like cellar that is really perfect!

Xu Yi pondered, and couldn't help but feel a little expected and a little proud.

I think I am the only one of a kind to build such a large cellar with pure wood. After all, even wood that has been treated with antiseptic treatment is still not as durable as cement bricks when buried in the ground, and the price of wood is getting higher and higher.

What's more, this cellar was completely made by himself, except for the wire and white latex, nothing else cost money, and it made people feel more and more fulfilling.

Out of the cellar, Xu Yi remembered the experiment he had done before, and took a few short bamboo tips and inserted them into the soil above the cellar to try repeatedly.

Xu Yi finally discovered that if the bamboo pole that was inserted did not touch the support on the top of the cellar below and did not expose the ground, then the bamboo would quickly decompose. But if this is not done, then whether the ground is exposed or the straw below is in contact with the ground, the bamboo inserted into it will not be absorbed at all.

The construction of this cellar did not change the previous effect of the soil at all!

Moreover, there is such a thick layer of soil left on the top of the cellar, no matter what changes in your thoughts in the future, no matter what is planted on it, it will basically not be affected by this cellar.

In fact, the soil needed for plants to grow is not as deep as expected. Under normal circumstances, if you plant annual herbaceous plants, the surface soil layer is only thirty or forty centimeters thick, and to plant perennial shrubs, you only need half a meter of soil, and you have left more than one meter of soil on top of this cellar, even if you plant trees on the top of this cellar, there is no problem at all!

Speaking of which, the underground parking lots in the urban area are just according to this standard, so what can't you do in your own space?

Of course, it is unlikely that the matter of not planting vegetables will be changed to planting trees, but Xu Yi thought that it was impossible for him to farm only by holding it on his shoulders, and if he had the conditions in the future, he would inevitably need to use farming machinery or use animal power to cultivate, and leaving the soil layer a little thicker is much better than when the cellar is crushed, or the livestock is trapped in the cellar.

After scattering the soil that had just been dug up and scattering it on the surrounding open space, so that the ground was restored to its original state, Xu Yi began to pack up his things, and tied up the bamboo scattered on the ground.

Of course, the cellar was dug, but there wasn't much to move in now, so Xu Yi moved those melons and sweet potatoes and the like, tore up a few large cardboard boxes, and put all these things on it and it was over.

Even so, Xu Yi is already very satisfied, now the tent is mostly empty, and when he wants to eat in the future, he can eat and pick it now, and only those who can't eat it need to be put in this. Of course, waiting for more wood, we have to make some more wooden frames here, which is certainly not very suitable and inconvenient to put on the ground.

In order to verify the effect, Xu Yi grabbed another handful of mint leaves and threw them on the ground, ready to see how long this thing could stay fresh in the cellar.

Xu Yi looked at the time, guessed the time outside the space, cooked dinner, took out the space for the two little foxes to add, and then poured the mint all over before it got dark, and then entered the space again.

After checking the fish eggs and tea leaves, there was not much change, so Xu Yi washed up and fell asleep by himself.

When Xu Yi got up to check the fish tank again, he was pleased to find that some of the small fish in the fish tank had grown tails. The small fish swam around in the water with a big belly like a pregnant woman.

Looking at the other fish eggs, they are basically fast, except for a few fish eggs but they have become less transparent again, and the fish eyes and those black lines on the turbid fish eggs have completely disappeared.

After all the fish tanks were inspected, Xu Yi found a total of more than 20 fish eggs that became like this.

Although relatively speaking, there are slightly more such eggs in the two fish tanks that use tap water, but there are only more than 20 such fish eggs in total, and the sample size is too small to allow Xu Yi to conclude that the hatching effect of space water on fish eggs must be better than that of tap water.

As for whether these fish eggs are caused by congenital defects or environmental factors, Xu Yi is even more unable to judge.

Despite such shortcomings, Xu Yi is still full of joy that the fish eggs have finally hatched! (To be continued......
