The taproots grew from the bottom of the sea to the land, straight across the beach that had taken the life of the Huqun, and headed for the highest point of the volcanic island.

Soon, the taproot met the two taproots that had landed earlier in the crater.

After the junction, the roots of the taproot take deep roots in the surrounding terrain and expand and grow in the rocky piles.

The microstructure of the rock is not solid, and the molecular-scale roots can easily penetrate into the rock layer and crisscross the rock without hindrance.

"Good, fixed rock formation done."

Hogu, who had already transferred himself to the inside of the titanium snail, watched with satisfaction the progress of the rhizome system on the volcanic island.

After encountering that super wave, Huo Gu was inspired that if he used physical means to achieve hardware transfer, he could transfer his thinking body to other cell clusters in disguise.

This extends a new type of rhizome, the inside of the rhizome is mainly the sensory cell, using this rhizome to bridge the nodule mass located on the seabed and the sensing area of the titanium snail, so that the two areas form a whole, after the mind is transferred to another area, cut off the physical connection of the rhizome, and the transfer is completed.

"The roots have built an intricate network of structures in the rock formations, so that the purpose of strengthening the geological structure of the island has been achieved, and the next step can be moved."

At Hogu's command, a taproot, which existed on the seabed, was apparently many times thicker than the other rhizomes, growing from the bottom of the ocean to the shore until it reached the foot of the volcano on the island, before stopping.

This taproot, while outwardly identical to the other taproots, is internally different.

Its interior is hollow, its coarse exterior is deceptive, and in fact its volume is no different from that of a normal taproot.

The reason why this taproot has become what it is is because it plays a central role in this project.

It did not march like a crater like the other taproots, but plunged headlong into the volcanic rock debris pile under the command of Hogu.

Through the information coming back from this taproot, Hogu could feel a strong resistance, which came from the rock formations, and it was clear that this was the result of the taproot being too large.

"Miscalculated, the pressure of the rock formation is even greater than estimated, although it is true that the taproot can continue to advance, but at this speed, I am afraid that it will be dug until the year of the monkey and the month of the horse to be able to dig through."

After being annoyed, Huo Gu thought of a compromise.

"In that case, let's divide it into three areas."

"First, the head is reduced to the thickness of the roots, which is the growth area, which is convenient for drilling in the rock formation."

"The part behind the head gradually grows the thickness of the normal taproot, which is the elongation zone and is responsible for extending the length of the rhizome."

"The part behind the elongation zone is the mature zone, and the rhizomes in the elongation zone will fully expand their internal space and form the necessary pipe cavities for the plan."

"Well, that's it!"

The rhizomes that received the instructions still grew forward through cell division in the rock formations, but they followed Hogu's idea.

The effect is really obvious, if you have to describe it, before the speed of drilling was the level of a person walking, now the speed of drilling is a Formula 1 car.

Hogu could clearly feel the decrease in drag.

There are no timing tools, Huo Gu does not know how long it has been, only that a considerable period of time has passed, during this time, Huo Gu used the remaining organic materials to expand the number of titanium snails to more than 30, and the number of hoists has also returned to the original level of more than 400.

Because there is no light in the formation, and there is no reference to determine the direction, this kind of thing is very likely to happen, and if you want to avoid it, Huo Gu can only use the information transmitted back by the entire rhizome system to compare and model with each other, but even this method also has the possibility of drilling crooked, so for one-time success, Huo Gu is not completely sure in his heart.

When Hogu received a signal, he knew that the drilling of the rhizome was finally coming to an end.

The triggering condition for this signal comes from the outside, i.e., the unnatural death of the cells in the head of the rhizome.

Hogu immediately ordered the rhizome that was being drilled to stop elongation, and the entire rhizome was turned into a mature zone, expanding the cavity channel inside to the limit.

The cells in the elongation and growth zones begin to gradually inject carbon dioxide into their own part of the cavity, using the volume of the gas to expand the cavity channel in the rock formation.

This is how the cavity is extended in the mature zone, where the pressure of the rock formation is fought against the gas rather than the rhizome itself, and the energy consumed is negligible.

Strength is inversely proportional to size, and the larger the size of the material, the less strength it has.

As the entire taproot is completely spread out in the rock formation, just a thin wall away from the rhizome, the lava with a temperature of up to 1200 degrees Celsius finally breaks through the wall and makes contact with the drilled rhizome.

At this high temperature, even the cell membrane that Hogu had specially prepared to resist high temperature did not help, and the first part of the taproot that had been charred and carbonized before was washed away by the lava flow in an instant, and the cavity pipe inside the rhizome was completely exposed to the lava flow.

Lava is also a liquid, and it also follows the law of pressure, pressure has nothing to do with volume, this law is only related to height, as long as the higher the height of the liquid, then the bottom of the container will be stronger, which is why there is such a strong water pressure in the deep sea, but not in the shallow sea.

Now, driven by the pressure of the water, the lava rushes along the cavity pipe inside the rhizome, rushing and impacting, and the rhizome cells can be destroyed by carbonization wherever it passes, but due to the high temperature of the lava, the extended pipe of the rhizome is still retained.

The surging lava does not always follow the trajectory of the cavity pipe, and at the moment it leaves the rock formation, the cavity pipe can no longer form any restraint on the lava flow, and the violent lava flow breaks through the cavity and scatters in all directions, as if turning into thousands of fiery snakes crawling out of hell, rushing towards the sea.

All this, in the eyes of Huo Gudu, also seems to be what it wants to do.

The rhizomes of the mountain were the victims of drilling through the base of the volcano to create a passage to release the lava.

The lava of this volcano is very fluid and does not easily clog up, which is the information that has been investigated in advance and summarized from the data.

When the lava of a volcano can no longer pose a threat, and can no longer form a confined space where pressure can be stored, then what danger is there?

This is the Volcano Renovation Project in Hogu.
