After scouting several layers in a row, with no practical gains, Allen led the team back to the surface.

Eat a game dinner on the ground and head straight to the other side of the island – the plantation grounds.

It takes an hour and a half to walk to the other side, which is quite far, and after Alan and the others arrived at their destination, they saw a tree planter coming to greet them, and another was still guarding the tree buds.

"Your Majesty, that tree species has been planted in the grassland, and the grassland withers rapidly within an hour, the grassland deserts within a range of 100 meters in two hours, and subsides in the sand within six hours, which has a great impact on the environment." The tree planters are worried and make no secret of their fear of the fruits of psychedelic trees.

The germinating psychedelic tree species overpowerfully plunders the elements of the land, while absorbing the heat of the air for its own energy, constantly developing and growing, with little to no need for orcs to take care of.

Alan pushed aside the dense grass, and the bright spot ahead illuminated the darkness of the night, the light of the torches.

The torches are long, one meter long each, and every four or five trees are placed on the grass.

Alan saw a hundred torches lined up, red flames flickering, illuminating the grass from near to far.

At the end of the torches, Alan saw the yellow sand settling in the grass at a very inappropriate pace.

Getting closer, Alan also saw the full view of the sand, which was a fifty-centimeter depression in the sandpit, and the original grass had been squeezed by the fruit, and instead a small scarlet tree bud was planted in the middle of the sand.

Its small roots are like red cobwebs, very small and thin, only about two millimeters thick, stretching along the sand to the grass, crossing the blurred dividing line between sand and grass, and reaching into the weak grass to absorb nutrients and energy.

"How many hours have you planted?" Alan stared at the delicious little red bud and couldn't take his eyes off it.

The tree planter looked down at his watch and reported loudly: "Seven hours and five minutes have been planted." ”

"It's grown into a bud in seven hours, and it's growing so fast." Many of the orcs in the army used to be hard-working people in an agrarian society, and they had been dealing with the land for the first ten years, and they knew very well the horror of this young shoot.

The bud has grown to 20 centimeters, and it is no longer a bud, but a small sapling.

The fruit has disappeared, listening to the tree planter, the flesh decays into water, the red micro roots are pulled out of the pulp, the red water is absorbed by the roots, and the roots are violently divided, forming a huge network of roots in less than a minute, absorbing soil nutrients within a radius of twenty meters.

Now Alan saw that the desertification of the land had spread to a radius of fifty meters, and it had begun to take the form of a sapling, and in the faint light of the flames, two red branches were drawn.

Alan looked at the little sapling, and a misty illusion flashed in front of him.

The illusion was not very real, and Alan filtered it out at once, which was instantly suppressed by his internal strength.

"Did you see the vision?"

"Your Majesty, I saw a small tree growing in the sand, surrounded by trees."

"I've seen visions too, but they don't last long, and they don't look stable."

Alan thought for a moment, and it seemed that the subject of the illusion was itself.

However, the new one did not have the gloomy and cold feeling of the ruins, it was cold from all directions, and at first it felt like tentacles, but later I learned that it was the root of a mangrove tree, slippery and frightening.

The next day, Alan led the orcs down to the minus ten floors, and the hall more than two thousand meters below the stratum was very empty, and there were no experimental equipment in it, and it seemed that the original site had been emptied.

It took Eren a few days to sweep to the minus twenty-ninth floor of the ruins, but there was no actual gain, and it was all a vast hall with no life other than the red roots.

Then Alan returned to the main floor, the third passage, the power distribution room.

Outside the distribution room is a large number of damaged units, rectangular machines neatly arranged in a square array, after powering on, some of the machines emit a faint glimmer, proving that it is running.

In the electronic control room, Allen inquired about the internal map of the institute and found that the research floors were all on the minus 90 to minus 100 floors, and the minus 1 to minus 90 floors were all experimental sites, which were specially used to hold experimental products and carry out various tests.

In other words, if Alan wants to get super technology that spans today's era, he has to go down to the minus ninety layer.

However, the minus 90 floor is not at the minus 2,000 meters, and there is a gap of more than 2,000 meters between the minus 89 and minus 90.

If you want to enter the minus 90 floor, you can only take the elevator shaft, which is the 5,000-meter pit in the middle of the road.

The elevator disappeared inexplicably, and going down the deep pit became a problem, which extremely tested everyone's ability to descend.

Fortunately, Alan had already considered the exploration plan of a 5,000-meter-deep well before he came.

Using a small internal combustion engine as a power source for the lifting platform, the soldiers were transported down to a 5,000-meter-deep well and into the core science and technology area of the Institute of Marine Biology.

The warship has a small internal combustion engine and a special extra-long wire rope, which is five thousand meters long and is tied by more than a dozen huge steel wire wheels.

It is very troublesome to transport this kind of thing, and it cannot be pushed by manpower, so it can only be done with the help of industrial machines.

In order to transport this thing, Alan specially ordered a small transport vehicle to be built in the automobile factory, which could enter the passage of the ruins and transport heavy wire ropes and lifting equipment machines.

These things had been transported to the gateway of the ruins a few days ago and had not been assembled, and now it was time to send someone to assemble the lift.

Allen's team gets busy, and the internal combustion engine transporter carries the bulky steel machine into the second passage of the ruins, regressing into the narrow terrain, then dropping the machine and returning to the point of origin, repeating the transport.

A day later, the orcs were assembled under the guidance of Allen, and more than a dozen wire rope wheels were lined up on the hard ground one after another, and the orcs put on oxygen cylinders and held guns, and stood next to the elevator shaft.

Inside the elevator shaft, layers of blood filaments grow along the walls, and its roots are rooted in the metal walls, sustaining life with extremely low power consumption.

The bottom is pitch black, and since there is no light at the bottom, the strong light shines on the bottom, reflecting the white light back to the lift platform.

Alan looked down and saw a pale white light at the bottom, and the bloodshot from the walls stretched below.

At a depth of five thousand meters, there is the core technology area of the entire ruins of the Institute of Marine Biology.
