When the system prompted that the research room had been upgraded, Ye Guchen put the red meteorite in, anyway, now everyone treats him as a spatial ability, which is nothing.

After that, Zhang Yurong took everyone away and scattered all over Hangzhou City, and it was impossible for them to rebuild Egg City until they killed the Air Fortress.

Du Fei and they are all outside Hangzhou City, now the monsters in the city are very powerful, mutants are not afraid of monster attacks, humans can't, they can only hide in places where monsters are scarce.

Ye Guchen teleported into the research room alone, the research center has changed, the structure of the room is gossip-type, the eight walls are like water curtains, and behind each wall is a space, which is a warehouse, a machinery manufacturing room, a material manufacturing room, an equipment manufacturing room, a biological laboratory, a medicine room, and two walls are blocked, and it is estimated that there should be new facilities opened in the future.

The treatment room and the drug manufacturing room are combined to form the medicine room, which is very large and independent. The largest is still the machine building room, like a large manufacturing plant, enough to accommodate a small warship.

Even if the battleship is small, the length is more than 100 meters, so you can imagine how large the machine building room is, and the area of the other rooms has also increased a lot.

"How much energy does it take to get all the technologies up to level four?" Ye Guchen asked.

At this time, a humanoid light and shadow formed by data appeared in front of him, with facial features but no color skin or anything, which was made up of data superposition.

"In addition to space technology, a total of 210,000 energy is needed, and the current reserve energy is 294863 points."

"Upgrade them all." There is so much energy thanks to the crystal nuclei that his daughters have helped him collect this year, and when he thinks of this, he smiles in his heart, he doesn't love them in vain.

"How much energy does it take to improve space technology?" Ye Guchen asked again.

"The fourth-level space technology can already open short-distance space jumps, so the energy required is 50,000, the fourth-level space storage technology needs 30,000, the fourth-level space exploration technology needs 50,000, the first-level space jump needs 10,000, the second-level space jump needs 20,000, the third-level space jump needs 40,000, and the fourth-level space jump needs 80,000."

"This space technology is really enough to consume, there are only more than 80,000 energy left, and the space technology and space storage technology have been upgraded to the fourth level." Ye Guchen said.

"Understood, all the technology is turned on."

"So fast! Now the technology is turned on in seconds! Ye Guchen was pleasantly surprised, since the technology was successfully opened, he said: "Show me what the fourth-level chariot technology can make?" ”

"At level four, the chariot technology has been upgraded to industrial manufacturing technology, which can make spaceships, and there are many types. If all four of them can fly in the sea, land, air, and space, it will occupy a lot of space, and the weapon system will be reduced, so it is up to the inheritor to choose what functions he needs. ”

After the system finished speaking, a three-dimensional image of the spaceship appeared in front of Ye Guchen, and he could choose various functions, including appearance and weapons.

He currently has no plans to go outside the earth, nor does he plan to go to the bottom of the sea to explore, the spaceship is so big, it is impossible to travel on the ground, there is not such a large road surface, so he only chooses to fly in the air. The others have chosen weapons and defense systems, and as for the basic configuration, he will definitely not be less.

A one-square-meter ammunition depot was built in the middle of the spacecraft, and after this door was opened, there was an independent space with a length of 10 meters, width and height, which served as an ammunition storage depot.

The supply warehouse is the same size, but it is located next to the ship's cockpit, so it's easy to access.

The ship's primary purpose is to fight, and he will save space to build the main cannon as a laser cannon, four rocket launch towers, twelve thermal beam cannons, twelve artillery turrets, barrage defense systems on all sides, and inducing missiles. Both thermal beam cannons and artillery are used to prevent weather changes from affecting laser weapons.

On both sides of the tail of the ship, a mechanical cabin and a biological compartment are built to store robot troops and biological weapons. The head of the spacecraft has a mecha compartment, which stores mechas, which are used to repair and replenish energy for mechas, and can also be used for aircraft and vehicles.

After all, the spaceship is so big, many terrains cannot be approached, and can only be replaced by aircraft or motorcycles.

Because Zhang Yurong likes red, Chen Guo likes black, and Fangfang doesn't have any special preferences, so she sets the color of the battleship to black and red, and the system will automatically design a color match that meets the aesthetics.

There are only two wheelhouses and a rest area inside the ship, and the others are passages and hatches. The area of the cab is actually very large, including the combat conference room and the command room, anyway, the people here are their own people, and he will not let outsiders come up casually.

The lounge area has a lot of separate beds, a bathing area, and of course, an entertainment room for everyone to have a meal and have fun.

After the setting is completed, click OK, and the machine building room will start building the ship, and the material manufacturing room will make the stored materials into the materials needed for the spaceship.

After setting up the most important spaceship, he asked, "What can be made of Level 4 equipment?" ”

"The last Transformers' metal material analysis has been successful, and it is recommended to use this new material to make firearms, as for weapons and armor, red iron is still used as the base material, this is the only material currently available that can be combined with source energy." The system makes recommendations.

Ye Guchen waved his hand, and the three-dimensional equipment in front of him flashed one by one, and finally he determined a black suit and said: "According to the Nightcrawler suit, the materials are the kind you said." The guns are Tyrannosaurus, Cobra, and Storm. ”

The Tyrannosaurus rex is powerful enough and has recoil, while the laser weapon has no recoil and feels not strong enough. The Cobra sniper rifle is slightly weaker than the laser sniper rifle, but it is adaptable to various terrains and can be fired underwater.

The Tempest is similar to a heavy machine gun, but instead of bullets, it shoots ionic balls, which have a powerful destructive power and a super high rate of fire, like a storm.

As for cold weapons, the materials of the fourth-level synthesis are already very good, and the combination of materials and technology makes weapons that are far beyond the comparison of third-level equipment, and it seems that the third-level and fourth-level technology is a dividing line. Ye Guchen customized a set of weapons according to their abilities and personalities.

"Understand, each person makes a set according to their own body type, right?" The system asks in an emotionless tone.

"They're smart, they've all had their bodies scanned." Ye Guchen took a look at this data humanoid and found that since returning from the dungeon, the system here was much smarter.

"By the time you meet your companion, it's all scanned."

"Good, let's make it. What is that red meteorite? Ye Guchen thought that aliens wanted to get this meteorite, and there must be something unusual about it.

"There is an extremely terrifying energy inside, from the structural analysis, plus the summary of the information obtained before, this is the heart of the Dark Emperor."

"Heart! You're kidding too? The Dark Emperor is huge, comparable to a planet, and his heart is at least like a mountain. Ye Guchen said in surprise.

"I don't know about this, from the structural analysis of the scan, it is a heart, which may be compressed for some reason, otherwise it is impossible to explain the origin of this thing." The computer analysis is to have the highest probability of high-speed Ye Guchen, of course, it will not be 100%, but this time the system has a 98% probability of being the heart of the Dark Emperor.

Ye Guchen touched it and said to himself: "The Void Marauder said that the ability of dark blood is the Dark Emperor's, and when he touched the meteorite today, the reaction of his body is indeed very suitable for this condition, if it is really the heart of the Dark Emperor, will there be a surprise if I absorb it." ”

"Your current body must not absorb the heart of the Dark Emperor, the heart is the source of the Dark Emperor's power, you can only slowly absorb energy from the heart to speed up your own evolution, and you must not absorb the heart, otherwise you will completely lose control, or explode." The system immediately admonishes.

"I know, it's just speculation, what are you excited about. Okay, I'll go back with nothing to do. ”

Ye Guchen was just about to leave, and the system said: "Inheritor, there are a lot of materials needed to make a spaceship, and the materials you have in reserve are not enough to make a spaceship, and there are a lot of materials around it, it is recommended to collect them." ”

"Lots of material! I almost forgot that three battleships were blown up, and all that was left was materials. I'll go now, you continue to produce, don't stop. Ye Guchen immediately teleported out and collected the three alien warships.

The fourth-level acquisition technology is very amazing, he just approached, thinking about collecting materials, and his body automatically shot out a traction light, compressing and sucking the battleship into the material manufacturing room. Ye Guchen walked around the three battleships like shopping, and in just ten minutes, the three damaged battleships disappeared.

"It's really convenient, before the spaceship comes out, you should be able to rest for a while, I haven't had a good get-together with them for a year, just relax in the past two days, tsk, the goddess is getting sexier and sexier now, or choose a day to marry her, otherwise you can only watch and not touch, this is really difficult." Ye Guchen muttered to himself and walked towards the meeting place.
