While Yao Lijuan and Luo Jing were chatting, Su Cheng came to the First Research Institute by car.

The first research institute is located in the suburbs of Pudong, covering an area of 100 acres and a height of 100 meters.

From a distance, under the sunset, the clouds reflected in the transparent aluminum make it look like a sacred fortress covered in gold armor, which makes people feel awe.

Through the electronic detection door, Su Cheng entered the research institute, did not visit and stay, took the elevator directly in the central area, and entered the underground tunnel.

Then he took a supersonic train and arrived at the base of the volcanic island.

I haven't seen each other for four and a half months, and the base of the volcanic island at this time has undergone tremendous changes.

The original rock cave has long been covered by countless transparent aluminum, the light blue sci-fi channel, and the hall that simulates the starry sky exterior scene, which makes people feel trembling and breathtaking at a glance.

The entire volcanic island base covers an area of not small, with more than 100 acres.

These 100 acres are divided into four major areas, namely a large research area, two manufacturing areas, and a large rest area.

The decoration style of each area is different, for example, the research area where Su Cheng is now located, the style is biased towards science fiction, and after passing through the research area and entering the manufacturing area, you will find that the decoration style has become thicker.

In the four major areas, except for the relatively empty manufacturing area, the buildings in the research area and the rest area are all honeycomb structures, stacked one by one, with hundreds of floors and a height of more than 300 meters.

If it weren't for witnessing the birth of this base, Su Cheng couldn't have imagined that such a huge underground fortress could be built in just a few months.

You know, this is a huge underground building covering an area of 100 acres and a height of 3 or 400 meters.

Of course, since he knew the magic of Science and Technology City, Su Cheng was no stranger.

This time I came to the base of the volcanic island, firstly, to visit the building, and secondly, Su Cheng wanted to upgrade the [Tunnel Construction Center].

Now, he has the [100-fold Time Variable Card], which can make the tunnel construction time crazy shortened.

In addition, there is also a 'Tunnel Building Center Upgrade Right', he only needs to use 50 mission points and 10 million technology points, and then use this upgrade right to directly upgrade the [Tunnel Construction Center] to the epic level.

The research area of the volcanic island base, a light blue sea whirlpool-style room, is the central control room of the entire volcanic island base.

The area of the control room is more than 40 square meters, and the [tunnel construction center] is placed in the corner to the left of the entrance, with an independent operation space, although it is not too large.

In addition to the [Tunnel Construction Center], there is also a three-dimensional projection console in the center of the control room, and after Su Cheng entered the door, he saw a red light flashing in the console area.

Then the tiny information unit was quickly assembled, and a miniature version of the three-dimensional map of the volcanic island base appeared in front of Su Cheng.

At the same time, in the three-dimensional stereotype, there are also a number of control points that can be manually operated, but because of the existence of an AI intelligent matrix, manual operation is generally not required, and if you want to adjust and control the facilities of the volcanic island, you only need to give a voice command.

"Dear owner, ONE is happy to be at your service. The three-dimensional picture flashed and changed to the appearance of an eight or nine-year-old girl.

This is a virtual image of the first generation of AI intelligent matrix, named one for it, this AI intelligent matrix, has the computing speed of a superconducting quantum computer, and also has no less intelligence than humans.

Except for the lack of emotion and learning ability, the rest is fine.

With it, Dian Yi can accurately investigate and screen out various information for Su Cheng many times, otherwise although Dian Yi is proficient in the Internet, the amount of information on the Internet is too large, and Dian Yi alone will not be able to serve Su Cheng quickly and accurately.

"No service is needed for the time being. Su Cheng glanced at one and found that the virtual projection was quite realistic, except that it couldn't be touched, and the appearance was no different from the real person.

"Okay, you're in this control room, you can call me at any time. ”

The voice fell, the picture flashed, the image of One disappeared, and the three-dimensional picture of the base of the volcanic island reappeared in the console area.

Walking to the [Tunnel Construction Center], Su Cheng included it in the Science and Technology City, and his mind sank in.

[Tunnel Construction Center Upgrade]: Intermediate to advanced, it costs 50 task points and 10 million technology points, may I ask the host, is it upgraded?

"Yes!" Without hesitation, Su Cheng directly passed silently.

In an instant, the mission points dropped to 1,266 points, and the technology points dropped to 66 million points.

This time, the upgrade of the [Tunnel Construction Center] was the same as the last time, and it did not take too long, and it only took 10 minutes to upgrade.

After it was finished, Su Cheng took out the 'Tunnel Construction Center Upgrade Right', and without hesitation, he used it again.

From advanced to epic, the time it takes has changed slightly, but it only increased from ten minutes to half an hour, which is harmless.

Bite!

[Congratulations to the host for raising the Tunneling Center to Epic]

After a pleasant prompt sound, Su Cheng immediately checked the changes.

The Tunnel Construction Center :(Epic) is also known as a tunnel construction platform, which can connect satellites to accurately locate two locations, build a supersonic train tunnel of unknown length and a diameter of 20 meters, or build a neutrino channel of unknown length and diameter.

Note 1: The supersonic train tunnel costs 1000 tech points per kilometer, and the neutrino channel costs 1 tech point per kilometer.

Note 2: It takes 24 hours to build a supersonic train channel every 10 kilometers and a neutrino channel every 10,000 kilometers.

Note: Neutrino channels can only be used or at least for 'escape trains'.

After reading the basic introduction of the epic [Tunnel Construction Center], Su Cheng was overjoyed.

"Sure enough, there has been a change, the supersonic train passage only needs 1,000 technology points per kilometer, which is ten times less than when it was intermediate and advanced, great!"

At present, Su Cheng's science and technology points are not much, if calculated according to the intermediate and high-level consumption, the current more than 60 million science and technology points, can only build more than 6,000 kilometers of tunnels, far from reaching Su Cheng's expected goal.

At this moment, more than 60 million science and technology points can build more than 60,000 kilometers of tunnels.

In this way, Su Cheng can use the tunnel built by the [Tunnel Construction Center] to circle the earth's equator and a half.

"Epic items, it's just different!" Su Cheng sighed in his heart.

In addition to the changes in the supersonic train channel, there are also neutrino channels, which are relatively inexpensive to build.

Because the neutrino channel is not a solid channel, there is no material cost, and when the science and technology city is built, it is only necessary to sprinkle neutrinos into the construction range in the form of a medium.

Moreover, neutrino channels are usually used for interstellar travel by train, and they are often counted in light years, and judging from Su Cheng's current situation, he is afraid that he will be a loser for hundreds of years, and he will not be able to make a neutrino channel with a length of one light year.

Because the unit of light year, even if it is 1, is too large.

Moreover, not to mention interstellar travel, let's just say that the construction of neutrino corridors, if you want to use it, you must have a corresponding train, otherwise you can't even go up the orbit of neutrinos.
