Night.

Girl's room.

"It's coming soon." The girl's voice rang out.

"Yes, sir." BT-7274 replied.

“…… Actually fled into a dead end...... I'm really panicking...... BT, what do you say? The girl's voice looked a little remorseful.

"What you say, even what I want." BT-7274 said solemnly.

"Thank you."

"It's time for you to go to bed." BT-7274 said.

"Well, right away."

The girl cut her hair, and subconsciously grabbed it on the bedside table, but unfortunately she was empty, and she was stunned for a moment and then smiled bitterly: "...... I forgot to give it to him......"

……

Under the lamp, on the slightly yellowed bark fiber paper, a few lines of Chinese characters were written on the traces of charcoal.

Faster: increase the current (draw a circle, the word current is highlighted)

Further: ...... Sniper tower or ......?

More accurate: ballistic computer, remote control, precision gear, fire control computer...... (All crossed out and blacked out.) ), a simpler approach is needed.

More stealthy: camouflage, preset battlefield (cross-out), IR radiation (emphasis).

Chen Zheng leaned on the table with his head in his hands.

In the glass of water next to it, the once hot fish soup has now cooled down, and the white fish fat floats on the edge of the soup bowl, in a semi-solidified state.

Chen Zheng has been in this state for more than two hours. After collecting the relevant data of the Red Lotus Titan, Chen Zheng wanted to make a plan about the purpose and objectives of the operation, but unfortunately it has not been completed yet.

High mobility, high attack power, and a keen perception system that makes it almost impossible to sneak attack...... In the face of such an adversary, no matter where the electromagnetic cannon is placed, it seems that it cannot pose a threat to it.

From morning to now, Chen Zheng thought of many methods, including presetting the battlefield, burying the electromagnetic cannon system, quietly accumulating energy under the cover of snow, and then suddenly firing at a specific time.

However, this design seems to be beautiful and avoids many problems, but the most important point is that it cannot be solved at all: how to get the opponent to step into the preset battlefield? What should I do if the opponent detects a trap before entering the preset battlefield?

Moreover, even if the other party has stepped into the preset battlefield, Chen Zheng still has a large number of problems to solve: such as fire control system, aiming mechanism, communication system, remote control system......

Whether it was to build a sniper station on a giant tree or something else, Chen Zheng had thought about it one by one, and no matter how difficult the fire control system was, it was difficult to solve it - with the current level of technology, he could not build a reliable computer chip, let alone have time to write a fire control system.

The complexity of fire control comes not only from the control of the mechanical structure, but also from the difficulty of integration in the software, and it is a joke to develop a reliable fire control system for a new weapon without huge investment and three or five years.

However, the problem of fire control is a hurdle that cannot be overcome no matter what, and manual control Chen Zheng has never thought about it - don't expect the glasses man and the five of them and the four star thieves of Scarface to be cannon fodder for the benefit of Chen Zheng.

And that's not all.

The Butcher and the Red Lotus Titan didn't come by themselves, they were accompanied by more than a hundred elite warriors.

After learning through the glasses man, he learned that if the star thief powerhouses were excluded, these warriors who were called elite would be able to exterminate them all if they picked out one or two.

If Norman and Roshan are excluded, then it only takes no more than 6 elite warriors to destroy the entire star thief camp - it can be said that the combat power of two elite warriors is equivalent to the strongest among the star thieves, and Chen Zheng and they have to face hundreds or even hundreds!

Coupled with the Red Lotus Titan of unknown strength, this realistic threat overwhelmed Chen Zheng a little.

Fighting against the powerful Titans and countless elites on his own, even if he gave Chen Zheng the power of a country, he might not be able to find a way in just fifteen days, and besides, there were only 8 days left.

What to do?

Chen Zheng silently grabbed the cloth bag that the girl gave him, opened it and poured out the contents inside.

The multicolored gemstones are tinted with a dull yellow halo in the light of the table lamp, making them look particularly delicate and beautiful.

However, there were no longer six, but seven—including the girl's own jasper-covered comb.

Suddenly, Chen Zheng hammered down the table hard.

He knew very well what the girl thought...... This is already the meaning of deathbed entrustment! She didn't have much hope at all, so she gave him all her own inheritance stones.

Unwilling.

Really unwilling...... The feeling that you can't do anything when you are clearly in front of you is as uncomfortable as a poisonous insect gnawing at your internal organs.

What to do?

Chen Zheng picked up the bark paper again, looked at the various plans written on it, and drew incomprehensible graffiti and pondered.

Hiding...... No way! The reaction speed is too slow to preset the battlefield.

How to solve the distance?

Sniper towers?

Still is...... Aerocraft!?

Right! Flying machines are a little more reasonable!

Suddenly, an idea suddenly popped up from the depths of Chen Zheng's mind:

Drone!

Yes, that's right, that's it!

Chen Zheng took out another piece of straw paper and began to write and draw frantically on it......

Material ...... for drones Wood is it! There are countless high-quality woods available here! There are also metals that can be used for structural reinforcement.

Engine & Fuel ...... Electric motors and zero-crystalline generators! From the energy supply system to the electric motor, there is no need to build it ready-made, just dismantle it directly from the abandoned snowmobile!

And it's far better to use an electric motor than a fossil fuel – the air at high is thin and the lack of oxygen supply can make the internal combustion engine less efficient, but the electric motor doesn't have this problem!

This means ...... Drones mounted on electric motors can fly very high, at least 10,000 meters is no problem, many modern propeller drones can fly up to 15 kilometers, that is, 15,000 meters high!

At an altitude of 10,000 meters, you don't need to consider obstacles, wind direction, and ballistic sinking caused by gravity when shooting from a high altitude!

And in this way, it is possible to consider directly replacing the fire control computer with the remote computing of the glasses man's server:

Chen Zheng had considered using the glasses man's server before, but according to the previous preset battlefield plan, the amount of data that each shooting unit needs to input is too much, and once it exceeds a certain amount of loss, it will lead to a greatly reduced timeliness, which means that the time from confirming the target to shooting becomes longer, and the result is naturally inaccurate.

However, the use of a drone platform will greatly simplify the amount of data processed by the fire control computer, and the final reaction time will be increased within an acceptable range.

Then the next question is engineering!

For a moment, all that remained in the wooden house was the "rustle" of charcoal brushing on the paper.
