At night, in a general laboratory in the port, sparks and lightning flew on the workbench, and Lin Chuan was assembling the first mechanical tracking and monitoring device in his life.

That's right, among the three plans recorded in the diary, Lin Chuan made a choice, the first one was to carry out research on mechanical tracking and monitoring devices.

The reason for this choice is actually the other two plans, and it takes a lot of time to prepare.

The research plan of [Flesh and Blood], whether it is virtual data simulation or previous data review, is a time-consuming and labor-intensive matter, and it takes a long enough time to prepare.

This research project can only be done slowly.

As for the research on the weaknesses of the Blood Spirit Clan, Lin Chuan actually wanted to carry out this plan first.

Since the Blood Spirit Clan is regarded as an imaginary enemy, and the Blood Spirit Clan is lurking in White Arrow Harbor, it is natural to carry out this research plan first.

However, the purchase of specimens from the Blood Spirit Clan is really a difficult problem, and it is difficult to buy them on the exchange of the Heart Yuan Battle Network.

This involves the humanitarianism of the Continental Convention, which prohibits the trading of living specimens on the Xinyuan Battle.net Exchange.

This sounds ridiculous, the Blood Spirit Clansmen who feed on blood and slaughter countless Terrans still have to talk to them about humanitarianism.

However, this is the case, and the Continental Convention does not discriminate against all people, and it is a decree that maintains the apparent peace on the mainland and cannot be violated.

Therefore, Lin Chuan's first plan can only be the research of mechanical tracking and monitoring devices.

For this plan, Lin Chuan's mechanical maintenance business has long had a prototype and is handy to carry out.

"It's done!"

Lin Chuan stopped, looked at the work in front of him, and nodded, quite satisfied.

On the workbench, there was a little mouse, Lin Chuan turned on the remote control, this little mouse moved, very flexible, lifelike, and could be fake.

Lin Chuan didn't know why he wanted to make the device model look like a guinea mouse, but when he was making the drawings, he suddenly thought of the model of the guinea pig and made it.

Perhaps, he thought of his previous situation, if he was a little careless, he would have ended up as a guinea pig.

Since I'm likely to be a guinea pig, why not make a guinea pig model and fiddle with it when I'm fine?

That's how man's inferiority is ......

Such a guinea pig is different from those remote-controlled toys sold outside, this is an advanced product that carries several black technologies.

The eyes of this little mouse are the tracking and monitoring devices that Lin Chuan has modified, which can detect areas within a kilometer in diameter.

Of course, if that's all it is, it's not a black technology.

The heart element power chip of this eye adopts a black technology of the eagle-headed man, which can achieve 30% of the [night vision eagle eye] effect.

The eagle-headed people in this world, the racial talent is detection and reconnaissance, and their talent [Night Vision Hawkeye] can clearly perceive all movements in a diameter of kilometers.

That's right, all the movements mentioned here, including those creatures who are good at stealth, can't escape the detection of [Night Vision Eagle Eye].

The 30% effect of [Night Vision Eagle Eye] is naturally not as powerful as the real [Night Vision Eagle Eye].

However, the prosthetic eye detectors are also able to penetrate the surface of the water, see the heat emitted by a creature's body lurking in the darkness, and distinguish the race of the creature. It also has a certain perspective effect, detecting what mental element armament the target is carrying.

The material of this pair of eyes alone cost Lin Chuan 500 gold coins, which is really expensive.

Another black technology on this mouse is the Xinyuan energy storage device, which is similar to the battery that stores the Xinyuan force.

In this world, there are also batteries, which are similar to those on Earth, and are mainly used in civilian devices.

However, similar to the R&D level of batteries for storing Xinyuan force, Lin Chuan really did not dare to compliment and was very backward.

Combined with the current situation of this world, it is actually normal, the powerful talents of various races, coupled with the strength of the Xinyuan armament, do not require a remote control type of Xinyuan power device.

Therefore, the volume of the cardio energy storage device in this world is generally very large, and the smallest one is the size of a fist, and the capacity is very average.

This Xinyuan energy storage device is improved by Lin Chuan, which is similar to the size of two No. 5 batteries on the earth.

After injecting the heart element power once, according to Lin Chuan's estimate, it can be maintained for three hours, which is very good.

"Squeak ......"

The cries of mechanical mice are indistinguishable from real mice.

"Not bad. The first test was made like this, which was quite good. My talent in mechanical maintenance is really not covered ......"

In the maintenance club of Nanluo College, the members of the club recognized Lin Chuan's talent in mechanical maintenance, but because of [Heart-Yuan Fit Disorder], he could not use mid-to-high-end instruments, and no one thought that he would have any achievements in this field.

After remotely controlling the mechanical mouse for a while, Lin Chuan felt that it was almost over, and the next thing to be carried out was the field control test.

"Since it is the first mechanical work in my life, it is natural to give it a name that pulls the wind......"

Lin Chuan thought for a while, but didn't come up with any good names, so he simply came up with a simple and easy-to-remember name - Xiaobai No. 1.

"Let's go! Xiaobai No. 1, the next step is the actual battle. ”

Putting the mechanical mouse in his pocket, Lin Chuan put on a hooded trench coat to cover his face, changed into a physical and mental element, and walked out of the general laboratory, heading towards the north of White Arrow Harbor.

——

North Neighborhood.

Lin Chuan's Xiaobai No. 1 actual combat plan was chosen here, not because it was mixed, but because there were other reasons.

Late at night, when Lin Chuan came to the northern block, he saw that the nightclub was still open, and there was a queue in front of the door, and business was very prosperous.

At the door of that nightclub, there was even a striking slogan - after the sweep, it was so safe!

From the conversations of the people in line, Lin Chuan learned that many people chose to patronize this nightclub because they saw this slogan.

"Kobolds are very good at business......"

Muttering like this, Lin Chuan walked towards the opposite side, his destination was the black market in White Arrow Harbor, two streets away from this nightclub.

The black market in White Arrow Harbor is actually a street.

Tourists from outside the area rarely come here, and the streets are quiet during the day, with few people haunting, and at night they are quite lively.

Walking on the black market street, the shops on both sides look normal, there are restaurants, handicraft shops, etc., but the prices are so high that tourists are scared away when they see the prices, muttering whether it is a street to kill people.

In fact, there is another mystery in the black market.

From Zhou Huan, Lin Chuan learned that the shops here all have another price list, which is only available to customers on the black market.

Lin Chuan came here, naturally, not as a customer, but to pick up work.

A shop in the middle of this street, the door of the store is a thick wooden door, Lin Chuan came to the front of the store, pushed the door and walked in.

The wooden door closes automatically, and behind the wooden door, there is a thick wooden door.

Lin Chuan pushed open the wooden door again and walked in again.

Behind the second wooden door, there is still a wooden door......

Lin Chuan pursed his lips and pushed open the third wooden door, and suddenly, the deafening music exploded.

"Just get a soundproof door, why bother...... Lin Chuan muttered and walked in.

The store was a pub full of customers, and the noise of noise, the pungent smell of alcohol, and the choking smell of tobacco filled the scene, and the scene was as chaotic as the northern neighborhood.

The guests here are very unusual, including white wolf people, bear people, kobolds...... In addition to the hostile aliens enacted by imperial decrees, many aliens who are known for their fighting talents can be seen here.

Moreover, these aliens are all fully armed, and some of them exude a faint bloody aura, and they all look dangerous.

When Lin Chuan walked in, a pair of eyes stared at him, and the dangerous sense of oppression was enough to make an ordinary person pee his pants on the spot.

When he saw Lin Chuan vaguely wearing a complete set of Xinyuan weapons, these eyes were all taken back.

A master of the ninth stage of the heart element!

Looks still young!

Don't mess with him!

This is the evaluation given by the guests in the bar at the first glance when they saw Lin Chuan.

"Huh......" Lin Chuan secretly breathed a sigh of relief, the first time he came to the exchange on the black market, he was really a little nervous.

This bar is an exchange on the black market, and it is also an offline exchange in this world.

In the Xinyuan Battle.com exchange, things that cannot be sold or traded can often be bought here.

In addition, it can also take orders and undertake some commissions here, and the strong people of the three major ministries often patronize similar black markets and take on some private work.
