The main role of the two dogs and turtle immortals is to clean up the excess fern leaves, bushes, wild grasses, etc. around the flat land, and of course, the most important one: digging trenches!

Not to mention, with the addition of the two big guys, Turtle Immortal and Buu, the speed of digging is obviously much faster.

Li Yan, on his side, took a stone axe and a stone pickaxe and began to decompose materials in the jungle near the Shinjuku camp.

It is true that the jungle is much more abundant than the beach.

There were trees, fern leaves, and stones everywhere, so he didn't have to run much at all, plus he had now comprehended the elementary alchemy, and the decomposition speed was much faster than before.

By the end of an hour, he had received a large amount of supplies.

Then, Li Yan led Buu back to the beach camp, connected the fibers into a rope, and brought back the woodworking platform.

With the carpentry table, he can turn wood into planks even faster.

A flash of blue light.

The planks of the 5 alchemy units disappeared and were replaced by a light brown plank that was one meter in length and width.

The thickness of the planks is about four or five centimeters, which is worthy of the system's name for "plank wall", which is quite strong.

Because the supplies are too abundant.

Li Yan also planned to make a good deal of the Shinjuku camp, so he used more than 100 wooden planks to form a huge wooden plank wall with a length and width of about 5 meters, about 25 square meters.

This one, he laid it directly on the ground, as a floor, and then put another layer of thatched planks on top of it.

Because the thatch planks are thin and all thatched, it is more comfortable to step on, but when laid directly on the ground, it is easy for moisture in the soil to penetrate up, so it is necessary to put a layer of planks underneath.

For the surrounding wooden walls, Li Yan used three wooden planks with a height of three meters and a length of five meters, which were inlaid on the four sides of the foundation planks.

Finally, a 25-square-meter wooden wall was pressed on top of the roof to serve as a roof, and a wooden house was built!

Because of alchemy, Li Yan doesn't even need to nail it with something like a nail, and he can decipher, decompose, synthesize, and glue two wooden planks together with a sticker with his left hand, but because there is no formula, the process is a little slow.

But it is also enough to make the roof, wooden wall, and foundation firmly glued together to form a tight whole!

Finally, he used a stone axe to dig a half-square-meter window on the left and right sides, and left a door for the doorway, replacing it with thatched planks.

The wooden house is made of its own wooden house.

Li Yan built a row of shacks for the remaining members of the dinosaur team.

For them, as long as there are wild grasses, they can keep out the rain and be comfortable to pick, and the requirements are naturally not as high as humans.

So, around noon.

He had already completed the construction of the wooden house, the domesticated creature shed, and the warehouse, the three main buildings.

Thanks to alchemy, a lot of human energy is consumed.

Although Li Yan didn't hunt creatures to upgrade in the morning, just by eating meat to recover his strength, he gained forty or fifty points of origin energy!

Suffice it to say how many times he had used alchemy this morning!

And in the afternoon.

The turtle immortals finally dug the trenches around the camp.

Li Yan once again synthesized several extra-long wooden planks in one go, forming a polygon that was almost circular, and surrounded the camp.

Because of the abundant supplies and the experience of being attacked by the Velociraptor last time, this time, Li Yan synthesized the planks of the wall, each with a height of more than three meters.

In this way, in addition to the dozens of centimeters buried in the trench, the rest of the exposed ground is enough to approach three meters, which should be able to withstand many dinosaurs under the small and medium-sized size.

Left with spikes to resist the horse.

Li Yan found the location where he had ambushed the Xiujaw Dragon before, that is, he found a similar "civilization ruin", where there was a large bamboo forest.

Bamboo, wood, fiber, stone.

Taking out the sufficient amount of materials required by alchemy, he put his left hand on it, and saw a flash of blue light, and all the materials in front of him disappeared, replaced by a huge spiked horse three meters long, 1.5 meters high, and one meter wide.

Unlike the simple spiked horse rejection in ancient times, it is completely composed of multiple triangles strung together, and compared with plane crossings, triangular crossings are more three-dimensional, more stable, and more defensive.

On each independent triangle, there are three extremely sharp bamboo thorns, pointing to different directions, connected by a huge straight wood in the middle, and each other is tied and fixed with fibers.

Underneath the spikes are many stones to stabilize the center of gravity.

Li Yan tried to step over, but found that it was indeed too difficult.

Because no matter which direction he jumps, he has bamboo thorns.

Just place it underneath the wooden walls of the camp.

On the one hand, it can prevent agile dinosaurs such as velociraptors from climbing walls, and on the other hand, against dinosaurs that like to collide, spikes can also stab them, or even kill them!

"Beautiful!"

With the last spike horse planted, in the twilight time, Li Yan finally succeeded in building the Shinjuku camp.

The whole campsite covers an area of about 400 square meters, which is smaller than the beach camp, but "the sparrows are small, but they have all kinds of organs".

It can be seen that under the square wall with a side length of 20 meters, there is a circle of bamboo thorns to resist horses.

And inside the camp, south of the center line, is Li Yan's wooden house.

To the west of the hut is a warehouse, and to the east is a shack for domesticated creatures.

In the vacant space in the middle, there is a fire and a carpentry table, which is regarded as a food, office, and entertainment area.

At this time, Li Yan opened the gate of the camp wall, and he could directly see the jungle, the tall and towering ancient trees around him, and countless various plants.

The evening sun, through the shade of the trees, hit him, pulling a long shadow in the camp.

Behind him, the dinosaur squad was wallowing in the yard, and in front of him, 100 meters to the north, was a glittering orange stream.

From time to time, there will be a few "bang" splashes in the stream, which should be an ancient man-eating pomfret swimming.

As the sun sets.

In the jungle, there will be the cries of various dinosaurs and fierce beasts from time to time.

Li Yan may have been scared before.

But with the improvement of his strength now, and the strong sense of security brought by wooden walls and spikes to resist horses, he felt that these voices had become a manifestation of "hilariousness".

After all, this is only the outer part of the jungle, and most of the active ones are small and medium-sized herbivores.

Even the occasional carnivorous creatures, at most bantams, raptors, and the like, could not even break through his camp.

Therefore, there is no need for him to be afraid.

Holding the bun and pinching its fleshy little body to play for a while, Li Yan gradually became a little sleepy, after all, after a tired day, even if there was a large amount of raw meat to replenish his strength, he could never relieve his mental fatigue.

And just as he was getting ready to sleep.

Suddenly:

Knock ——!
