Chapter 406: Excavation (2)

The growth rate of the construction vine is very fast, especially after the recovery period of the seedlings, and its advance speed can almost be described as rapid. At the beginning of the pen "Fun" Pavilion www.biquge.info, Cheng Mingli's squadron only needed to turn on the auxiliary power on the alloy armor to keep up with the advancing speed of the construction vine. But just one day later, the speed of the inner passage of the building vine was almost beyond the speed limit of the hovering car.

So, two days later, a strange sight appeared in the underground passage: a convoy of thirty armored hovercraft was running desperately in the underground passage with a diameter of more than fifty meters. In front of it, a pale green light was rapidly moving forward, and even as the team continued to increase its speed, the distance between it and the aperture continued to widen.

A week later, the green circle of light in front of the convoy was long gone. The convoy has gone more than 110,000 kilometers underground, but the road ahead still seems far away. You must know that the diameter of the earth is only more than 10,000 kilometers, which means that Cheng Mingli's squadron has now passed a distance of more than ten earth diameters underground.

The inside of the passage is no longer as dark as it was at the beginning, and the fibrous plant tissue that runs through the inner wall of the passage emits white plant fluorescence and gently sprinkles the entire passage, and some nodes even change to yellow or even green fluorescence. Brown and dark green plant patterns adorn the walls of the passageway, making it look like a newly renovated log cabin.

The hovering convoy of "Huhuhu......" at a speed of 650 kilometers per hour is still speeding in the passage, and the green spots on both sides of the continuous flying backwards indicate that the convoy has passed through one key node after another. These nodal areas are much richer than the straight tubular channels, like expanding spheres. According to the genetically encoded program, it is divided into a series of functional compartments, some of which serve as temporary warehouses, some as monitoring centers, and some have the function of combat defense.

......The hum of the hovering car's energy engine gradually died down, and the convoy stopped at the next node. The time for the node to form is only three or four days, and after entering, you can still ask for the fresh woody fragrance. Near the inner ring, a five-meter-diameter circular platform sits silently, surrounded by a low wooden staircase with a patina-green metallic sheen.

After sensing that someone entered, the lighting system in the monitoring room was immediately activated, and the white light lit up from the walls around the monitoring room and at the top, illuminating the originally dim monitoring room.

Mingcan, who had already taken off her space suit, slowly walked to the side of the circular platform, took out a yellowish injection from the space watch, and dropped two drops into the groove next to the platform. The next moment, a green light lit up from near the groove, and then quickly spread towards the entire platform, until the entire platform was covered.

In the center of the platform, the tissues that had stopped growing began to slowly protrude, and finally a cluster of crystal-like diamond-shaped polyhedron grew. The crystal cluster looks like a model of a tall building, with a transparent triangular crystal in the center, surrounded by a short red and yellow hexagonal prism. The outermost ring is a shorter piece of sapphire, which is less than 30 centimeters tall at the highest point of the entire crystal building model, which looks like a beautiful crystal ornament.

The "Buzz ......" The crystal resonated when it was charged sounded, and the crystal model began to glow gradually, and then these rays of light folded and bent each other on the platform, and a holographic map was displayed in front of Cheng Mingli and Mingcan.

On the holographic map, the vertically downward underground passage has extended to the extreme depth, and there is a string of light points in the part of the passage close to the ground, representing the location of the passage node where Cheng Mingli and others are located, and the distance from here to the ground only occupies less than one-fifth of the total length of the passage.

"In order to prevent the nodes from being occupied by the enemy, the monitoring center of each node must be activated before it can be used, and these monitoring rooms also have an extremely strict verification system, if the answer is wrong, outsiders will not be able to get any information they want from the monitoring room," Ming Cang explained in a gentle tone when he saw Cheng Mingli's inquiring gaze.

"And how did you just do that?"

"As you can see, I used pheromones to activate the holographic projection platform. Different kinds of pheromones activate the platform to different degrees. The smallest can only monitor the environment around the node in front of them, and the largest can monitor the every move of everyone in the entire channel," Ming Cang replied with a soft tentacle. It's hard to imagine how a turtle man with such soft upper limbs can pass the certification of a purple-collar engineer, and such a tentacle may not even be able to pick up a tool with a larger quality, Cheng Mingli scolded in his heart.

"Can you give me one of that plant hormone, you know, as the temporary commander of this mission, I must be able to monitor the overall situation anytime and anywhere," Cheng Mingli asked with hot eyes.

"I'm sorry, friend, your authority is not enough" Ming Cang politely rejected Cheng Mingli's seemingly reasonable suggestion.

"Haha, I'll just say it, forget it if it's inconvenient" Cheng Mingli said this, but secretly kept scolding Ming Cang for being stingy, and decided to find a way to beat Ming Cang out of anger when he turned around.

"Look, the growth of the passage has stopped ahead!" The white, soft tentacles pointed at the holographic projection, and the bottom of the projection began to zoom in rapidly near the end of the channel. It is clear from the holographic projection that the passage does not move forward once it arrives, as if something is hindering the vine from continuing to advance.

"Are we at the end? How could it be so fast? This is a superstar of 120 million kilometers," Cheng Mingli was puzzled.

"No, it should be the front end that has arrived at the magma sea, and the third-generation building vine does not have the ability to expand in the magma for a long time. From now on, the top of the vine will gradually begin to differentiate, and then form a bioenergy converter, which will continuously draw energy from the lava sea to supply the energy consumption of the entire channel. This is the preset program for the design of the third-generation building vine," Ming Cang said as he clicked on the biosensor on the top of the building vine.

"Boom! ...... "I saw a fiery red on the sensor, and the golden magma torrent was constantly raging, spurting rapidly in front of the probe like a river...... (To be continued.) )
