Late at night, early in the morning.

An extremely rare locomotive, like lightning, was speeding through the empty streets of Nandu.

The rider of the motorcycle was dressed in a black tights that were inconspicuous in the dark, and through the curves of the tights, it was not difficult to tell that this was supposed to be an adult male.

More than 20 minutes later, the locomotive came to the vicinity of Huwangling.

Sun Cheng slowed down and deliberately walked around the neighborhood before quietly driving into Base No. 1.

"It should be safe!"

He took off a pair of wide glasses on his face, and the lens of his left eye showed a radar scan interface.

This is a small prop he created with his confused body when he was in the [Transformers Universe], it is a small-area electromagnetic wave scanner that can detect electromagnetic fluctuations within a range of 20 meters centered on itself when turned on.

Sun Cheng was not careful, since he started contact with the state, although he broke some of the monitors placed by the National Security Bureau near his house last time, the other party has not approached to monitor his movements since then.

However, judging from the information gathered by the Vengeance and the Ultra Detective, there are at least seven other teams around his house and company that are monitoring him.

It's just that the other party has a tacit understanding to keep the surveillance far away from the scope that does not affect his normal life and office, so Sun Cheng also pretended not to know.

With so many people around him now staring at him, he had to be cautious.

In fact, a few days ago, Sun Cheng asked Revenge to rent a rental house not far from his villa through the Internet.

Tonight, he used the optical invisibility cloak to avoid the eyes of those who watched him, and then went straight to the rental house.

Here in the rental house, a locomotive that was also purchased by Revenge through an online order has already been parked here.

Sun Cheng doesn't have a motorcycle license, but what to say about this thing, it's not too difficult to get started.

In the previous two nights, he had secretly ridden a motorcycle on the road for hundreds of kilometers in the middle of the night, but unfortunately there was no time for him.

After making sure that the surroundings were safe, Sun Cheng took out an ordinary-looking key from the spherical space and opened the iron door on a wall that had been erected high on the perimeter of Base 1.

Stopping the locomotive behind the iron gate, he cautiously locked the iron door and glanced at a camera mounted in a hidden position not far away.

Immediately, Sun Cheng opened his mouth and said: "It's me, defend, lift the vigilance!" ”

From the hiding place, a metal spider the size of a children's doll quickly crawled out, and at the same time, the cold mechanical sound also sounded with the appearance of the metal spider.

"Yes, master."

Empty and lonely hills, familiar and strange places.

Although in the real world, Sun Cheng has only been here for more than a month.

But if you really count it, plus the time he spent in the [Transformers Universe], this time has been more than half a year.

More than half a year is enough time to make many things that were originally familiar feel strange when they see them again.

Although Sun Cheng is also experienced, this familiar and unfamiliar feeling still makes him feel very uncomfortable every time.

At the entrance to Base 1, a camouflage net has been installed, a special device created using optical technology.

It is able to simulate the surrounding environment, and perfectly conceal the entrance to Base 1, even if someone approaches the entrance a meter away, as long as they do not reach out and touch it, they will not be able to detect its secrets at all.

I haven't been here for a while, and if there is no metal spider to lead the way, even Sun Cheng will have to search near the entrance for a while to find the hidden hole.

Even though he had learned the magic of piercing through walls, his figure crashed into a mountain wall at the foot of the mountain, and then entered a long passage.

The lighting in the passage is not fully turned on, so the lighting appears slightly orange.

Sun Cheng didn't pay much attention to this, he walked straight towards the depths of Base No. 1.

After six or seven minutes, I came to the main control room of the base, which was located nearly 100 meters underground.

“…… Master, defend to report to you! ”

In the main control room, the defense that changed into a battle form bowed slightly to him respectfully.

Sun Cheng nodded, "I worked hard for you some time ago, I just noticed that two more workshops have been built!" ”

A week ago, when he realized that he might be targeted, he had already ordered the defense to temporarily halt the construction of Base 1.

However, he apparently underestimated his ability to defend the hundreds of robots he had brought back.

Several underground factory workshops at Base 1 that were originally parked on the plan are now nearing completion of two workshops, and one is more than half completed.

Don't think it's built underground, just because it's small.

Although Base No. 1 is far less than being located in the [Transformers Universe] world, the No. 2 Base with a total construction area of more than 12 square kilometers has already exceeded 12 square kilometers.

But after all, this is the most important rear base in the main world in Sun Cheng's original plan.

Therefore, the area of each factory floor in the underground factory area of the site will vary depending on the planning and future targeted production tasks.

For example, the two workshops that have just been completed in the factory area of the No. 1 base not long ago, one of which is slightly larger, has a construction specification of 50 meters * 30 meters * 5 meters, which will be used for the production of medium and large equipment parts in the future.

The other, slightly smaller workshop, with a construction size of 40 meters * 20 meters * 5 meters, is a workshop for the maintenance of industrial machines.

Because the base is built underground, it is not simply a matter of using robots to excavate a huge space, and then build a layer of masonry on the surrounding walls, and then apply cement.

Huwangling is not far from the Yangtze River, and the underground water system is rich after all.

When starting construction of an underground base, it is necessary not only to deal with the problem of underground water infiltration, but also to consider the possibility of future earthquakes and military strikes.

It is no exaggeration to say that according to the standards of the No. 1 base, such a workshop will not be able to be built by a human construction team in more than a year.

In less than a month, two of them were built, and at the same time, the completed area of Base 1 exceeded 30,000 square meters, which is a testament to its efficiency.

Defending said respectfully again, "The batch of construction robots sent by the master last time has helped a lot, and their efficiency is nearly twice as fast as the original industrial robots. ”

Construction robot is a special robot specially improved by Decepticon engineers on the basis of industrial robots to build underground facilities.

With the experience of tens of millions of square meters of underground engineering operations in the [Transformers Universe], the efficiency of this construction robot transformed by Decepticon engineers is indeed higher than that of ordinary industrial robots.

Sun Cheng nodded, "I brought another batch and put it in the warehouse later." Later you activate them, and by the way, you can load up the other batch of equipment I brought. After a while, I need you to produce a batch of equipment for me, and I will purchase and send the raw materials as soon as possible. ”

"Yes, master!"
