Although the three-headed monster of crocodile, giant wolf and gorilla is large and has evolved by devouring the flesh and blood of the monster, this evolution is similar to that of the giant python in the jungle of Paran Province of Borneo and the dinosaurs on Nubi Island. It simply increases the size of the body and the thickness of the scales, and the blood cannot cause environmental pollution.

But even so, in the face of overwhelming thermal weapon attacks, these three-headed monsters still could not escape the fate of the cycle of death.

At three o'clock in the afternoon of the same day, with the cooperation of the [Freedom Fighters], the Mi military dispatched to kill the three monsters one by one.

It was only at this time that Scott agreed to cooperate with Cai Tiantong and them, activate the [Tiger Guard], and let the [Tiger Guard] return.

........

North American Division, No. 3 Mecha Maintenance Workshop.

Zhang Xiaojiang followed Lin Feng, and after entering the factory, his eyes were full of amazement just like Grandma Liu entering the Grand View Garden.

This was the first time he had entered the mecha workshop, and those huge steel machines seemed to have an infinite attraction for him, a person who had loved mecha since childhood.

Lin Feng, under the leadership of technicians, came to the 175-meter maintenance room and began to wear special combat uniforms for mechas.

After putting on the combat uniform, enter the mecha head cockpit again.

"Professor Lin, are you ready?"

The person in charge of activating the mecha is Cai Tiantong.

"Well, no problem!"

"Okay, ready to launch!"

As Cai Tiantong's order was issued, the jaws that clamped the mecha head were loosened, and the mecha head, which weighed several hundred tons, slid down the vertical shaft at a uniform inclination.

A few seconds later, the head of the mecha was embedded in the neck of the mecha, and a red giant appeared in the empty factory.

At this time, Zhang Xiaojiang stood in a corner of the factory, staring intently at every link of the mecha assembly, watching the red giant appear in front of him, looking up and staring, he couldn't help but feel excited in his heart, and the metal noise in his ears sounded like a stirring music.

Looking at all this, Zhang Xiaojiang was so excited that his face was red, and he kept muttering in his heart:

"This is a mecha, a real mecha!"

At this time, Cai Tiantong gave the order again.

"Start the power system!"

"The power system is starting, 5....4....3...2...1!"

Whew, I saw that the reactor on the chest of the mecha suddenly released a flame, and the bright flame illuminated Zhang Xiaojiang's face even redder.

"Activate the nerve connection!"

"Neural connection starting, 5....4....3...2...1!"

With the completion of the nerve connection, the [Tiger Guard] initiation program comes to the last step.

"Give the authority to the driver!"

With the transfer of authority, Lin Feng had all the permissions of the [Tiger Guard], and he tried to raise his hand, and the huge palm of the [Tiger Guard] was also raised at the same time.

"Professor Lin, three kilometers away from the pier, the cruise ship is ready!"

Lin Feng nodded, and then controlled the mecha, taking the steps of the six relatives who did not recognize him, walked out of the factory gate step by step, faced the slanting sun, came to the dock, carefully walked on the cruise ship, and then with the help of the staff, fixed the huge body of the mecha to the cruise ship.

Sending the mecha to a cruise ship is a bit troublesome, but this trouble is much simpler than lifting it with an airplane.

Zhang Xiaojiang followed [Huwei] and witnessed the whole process, putting aside the excitement at the beginning, he was now conceiving the thesis requested by Lin Feng in his mind.

Yes, papers.

Lin Feng's third topic was to ask Zhang Xiaojiang to write a paper on mecha based on what he saw and heard on this trip.

The paper must be well-founded, not arbitrarily excerpted, nor fanciful.

For the thesis, Zhang Xiaojiang already had an outline in his mind at this time.

.......

"Professor Lin, here's your box!"

After being busy for more than an hour, he finally successfully sent the mecha to the cruise ship, and just after changing his clothes, he ran into Zhang Xiaojiang.

"Thank you!"

Lin Feng politely took the suitcase, because the time was in a hurry, and his test on the intelligent system had not yet been done.

However, there are opportunities ahead.

Because Lin Feng, like everyone else, chose to return to China on a cruise ship with [Tiger Guard].

The speed of a cruise ship is not as fast as that of an airplane, and the journey back home takes at least about three days.

...............

His car was smashed into scrap metal by the monster, and it is impossible for Mike to have no grievances, but fortunately, Faulkner's "Yago" luxury cruise ship is about to sail, and he can sail with the cruise ship, be responsible for the daily maintenance of the cruise ship, etc., and when he returns, he can receive a large amount of bonuses.

The "Yago" luxury cruise ship, worth 1 billion US dollars, weighs 225282 tons, is 362 meters long, 63 meters wide, and the size of the entire cruise ship is equivalent to three and a half football fields, which is 5 times larger than the Titanic. 630,000 gallons of paint were spent on the "Yago" alone.

The cruise ship has a capacity of 5,400 passengers and 2,394 crew members. It consumes 2.35 million litres of fresh water per day, has more than 10,000 square metres of retail space, 37 bars and 20 restaurants. "Yago" has the world's largest offshore swimming pool, which can hold 2,300 tons of water. Its 16-deck outdoor park has more than 12,000 real plants, including hundreds of palm trees. To illuminate the 2,700 cabins, more than 5,311 kilometers of cables are used on board. The Oasis of the Seas has an arena with a capacity of 750 people, as well as an ice rink, surfing machines, and a high diving venue.

The Yago cruise ship can be called the most luxurious cruise ship in the world, and Faulkner has made a lot of money in order to restore the maritime industry.

Of course, on this maiden voyage, the number of passengers was only two thousand, less than half of the full capacity, after all, only a few people dared to risk being attacked by monsters, traveling by boat, most people, would not dare to risk at this node.

Although Faulkner has done a good job of promoting the Yago, it is the safest cruise ship in the world.

With the elimination of the three-headed monster, Luoshanji regained its vitality, and the 'Yago' officially sailed out of the port of Luoshanji at four o'clock in the afternoon.

However, the loading of the [Tiger Guard] cruise ship and the departure time from the port were delayed until 7 p.m. local time, because there were still many things that had to be handed over to the North American branch before leaving.

.........

After dinner, Lin Feng returned to his room, opened the suitcase, took out the hard disk inside, and then connected to the computer, carried the computer into the mecha cockpit, and connected the computer to the mecha's control system.

"Ding, a new format file has been discovered, and it is being read!"

It takes a full 10 minutes for the intelligent system to complete the reading of the files of the control system.

"Xiaobai, can you activate this mecha?"

"Can't!"

The answer of the intelligent system poured cold water on Lin Feng.

"Why?"

Lin Feng couldn't figure it out, the purpose of his intelligent system was to start the mecha alone, if he couldn't, then the significance of this intelligent system would be greatly reduced.

"There are two split points in the control system of this mecha, and these two split points are closed and need to be manually activated!"

Eh, Lin Feng was very surprised when he heard this, could it be that in addition to the background permissions of the mecha [Tiger Guard], there are other means of restriction?

"These two dividing points, one is to block the transmission of nerve signals, and the other is to limit the sympathetic signals of the mecha's legs..........."

With Xiaobai's explanation, the more Lin Feng listened, the more frightened he became, there really were other restrictive means for [Tiger Guard].

But when I think about it in a moment, I am relieved.

After all, the mecha is a sharp weapon of the five major divisions, this weapon is too destructive, history has proven this, if the restriction means alone are pinned on the background authority of the mecha, then it is too much to take it for granted.

If you encounter a top hacker, won't the mecha be scrapped?

There are three holes in the cunning rabbit, so the three restrictive means are inevitable.

"Where are those two dividing points?"

"I don't know, there's no relevant information in the database!"

Lin Feng was speechless, but this is normal, as for the other two restrictive means, it must be taught by word of mouth, and it is extremely confidential, how can it be possible to leave information.

It's just a pity that my idea of simply relying on the intelligent system to start [Tiger Guard] has failed.

However, Lin Feng didn't care, after all, [Tiger Guard] was not his mecha.

After completing the test briefly, Lin Feng returned to his room.

Now that the intelligent system has proven its usefulness, it's time to plan for the next mech.

So Lin Feng turned on the computer again and began to design the drawings of the next mecha.

First of all, there is the power system of the mecha.

The previous [Chixiao] was a nuclear power system, and instead of one use and one backup, two nuclear reactors were used at the same time to power the mecha.

But for this mecha, Lin Feng must consider triple nuclear power, because to equip the mecha with wings, if you want the mecha to fly, and push the big guy of several thousand tons into the sky, the power required is a massive number.

Lin Feng even suspected that the three-core power might not be able to maintain the power operation of the mecha, and the four-core might be needed.

However, the quad-core power is too exaggerated, and if the quad-core is chosen, then the size of the mecha alone is a big problem, and it is too crowded to put four nuclear reactors in the mecha.

Moreover, the more nuclear reactors, the greater the risk factor.

If you smash a nuclear reactor during a fight with a monster, it can easily cause a chain reaction.

Therefore, Lin Feng's idea is to have three nuclear power, with two uses and one backup.

The dual-purpose design is the same as that of the [Chixiao], as for the first backup, it is provided for mecha flight.

In terms of operating system, Lin Feng still chooses the analog system, but this time it is not only an analog system, but also an operating system.

The two operating systems can be switched freely or assist each other.

Regarding weapon systems, this is the focus in mecha design.

The first is cold weapons.

The design of the cold weapon, Lin Feng had planned to abandon the chain sword and choose the chain knife, the chain knife is placed on the legs of the mecha, and the weight of the chain knife is used to balance the balance of force when the mecha flies and walks, so as to prevent the phenomenon of being top-heavy.

Mechs have thicker legs than arms, and the size of the weapons they can hold is definitely larger.

Therefore, Lin Feng's design for chain knives tends to be Tang knives.

Tang knife, narrow straight blade, small fang, long handle shape.

The Tang knife was originally a war knife of the Tang Dynasty army, and its biggest role was to fight, and its production process was strict, and it also had to take into account another use in battle, that is, armor piercing and durability. Armor piercing requires hardness, and the edge is narrow, and durability requires toughness, so the Tang knife blade material that Lin Feng needs is likely to be pinned on the yttrium ore of Skull Island.

The blade of the Tang knife is narrow and straight, but when Lin Feng designed it, it was impossible to completely imitate the size and proportions of the Tang knife.

So the next mecha weapon's Tang knife, Lin Feng designed a length of 70 meters, a width of 7 meters, and a thickness of 1.9 meters on the back of the knife.

And it's a double knife on the left and right.

Although the length of these two knives may not be advantageous compared to [Tiger Guard], the double knives of [Tiger Guard] are carried on the back, and it is impossible for Lin Feng to design it like this.

The 70-meter-long knife is embedded in the legs of the mecha, and it is definitely impossible for the legs of the mecha alone to reach 70 meters long.

The body structure of the mecha generally refers to the body structure of humans, and the most standard human body ratio is 0.618:1, that is, the length below the navel is higher than 0.618 for the whole body. The leg length ratio is 0.484:1.

In other words, even if a mecha is 100 meters tall, its leg length is only 48.4 meters, and the full leg length is 61.8 meters.

The full leg length cannot be used on the mecha, and the leg length on the mecha generally refers to the leg length in the narrow sense, that is, 48.4 meters.

It is undoubtedly troublesome to inlay a 70-meter Tang knife with a leg length of 48.4 meters.

Lin Feng simply chose to fold the double knife in half, and after the double knife was folded in half, its length was only 35 meters.

It seems a little less.

Maybe you can get two 90-meter Tang knives.

But if the Tang knife is too long, it will have a great impact on the balance of the mecha, and Lin Feng doesn't want to design the mecha himself, and when he fights with a knife, he has to take the step of not recognizing the six relatives.

So Lin Feng changed the Tang knife design to 80 meters, and the width and thickness remained the same.

Even so, the weight of the 80-meter chain knife reached 519 tons, and the weight of two chain knives was 1038 tons.

Then when using the double knife, aside from the mechanical stability structure of the mecha itself, the back needs to provide at least 570 tons of balance force.

To put it simply, the weight of the wings of the mecha must be more than 570 tons.

As for how to design this 570-ton wing, Lin Feng has no plan at present, because this is the first time to install wings on a mecha, and there is no similar experience before, Lin Feng must go to the aircraft factory to learn relevant knowledge to decide.

This back and forth seems to have to drag on the mecha manufacturing time again.

However, the employees of the Xiaofeng Mecha Construction Company could not afford to wait for such a delay, so Lin Feng planned to strip off the wings of the mecha and design the parts of other parts of the mecha first.

In addition to cold weapons, then there are the hot weapons of mechs.

In terms of thermal weapons, Lin Feng felt that it should be in line with the current stage of mechas, such as anti-monster missiles.

There are many types of anti-monster missiles, and the commonly used is the AKM anti-monster missile, even this missile, after more than ten years of research, the fourth generation has been developed.

Lin Feng prepared to crash the fourth-generation anti-monster missile into the belly of the mecha.

After all, the three-core power system needs to occupy the chest space of the mecha.

Ordinary mechas, the abdomen position is rarely equipped with weapons, because the abdomen is too low, if you fight monsters in the sea, the mecha's abdomen is flooded by the sea, and it is easy to lose the effect of the blow, or even cannot be used.

But Lin Feng did not shy away from this, he didn't like to fight in the sea, because for him, fighting in the sea could not use his legs, the restraint was too great.

In view of this, Lin Feng unceremoniously installed the anti-monster missile in the belly of the mecha.

At the same time, the length of the mecha's legs was also raised by Lin Feng.

In addition to the location of the anti-monster missile, Lin Feng paid more attention to the number of anti-monster missiles this time.

Because the last time [Chixiao] went into battle, the number of shells was too small, and he suffered a loss.
