Lin Fan is ready to build a spaceship that combines alchemy and technology, in the past four years, everything he has done is to lay the foundation for this matter, about the materials needed to build the spaceship, the design of various parts, the power system, etc., he has a clear mind, and the design drawings of the spaceship have been slowly drawn in the past four years.

After the banquet, Lin Fan returned to the Alchemy Tower and officially launched his own construction plan, the industrial area began to enter a closed state, and all factories and machines stopped other production tasks to serve the construction of spaceships.

With the implementation of the plan, a car of different kinds of ore is constantly transported to the various smelting blast furnaces, these blast furnaces are Lin Fan will alchemy and science and technology combined research products, the huge smelting blast furnace from the throat, furnace body, furnace waist, furnace belly, furnace cylinder 5 parts, all with some red lines, after the blast furnace starts, the lines on it have been exuding a faint light.

Various kinds of ore are fed into the blast furnace in specific proportions, and then dissolved into a black metal liquid, which, after condensation, becomes a new type of alloy metal that can be processed into various armor and hull parts of the ship.

This new alloy is the best quality metal material researched by Lin Fan in the past four years, and it is very excellent in terms of thermal insulation performance, radiation resistance, toughness, etc., and the comprehensive evaluation can reach 1.4 grade.

Originally, Lin Fan assessed the knowledge of mechanical civilization inherited from the holy relics that day, plus some scientific and technological civilizations he learned from Mu Yaxing during the expedition, and the civilization knowledge he mastered had just reached the level of a 1.3-level civilization, but after combining alchemy, the quality of the metal he had researched was forcibly increased by 0.1 level.

In the various assembly halls in the industrial area, various metal parts and components from different workshops are gathered together and then assembled one by one.

Countless robots are like industrious worker ants, busy in an orderly manner, and the shape of the spaceship is gradually revealed.

It took more than half a year to be busy, and almost all the materials in the industrial area were exhausted, before the ship was built.

It is a large armed ship with a triangular shape, a length of 3,800 meters, and a tail width of 1,800 meters, and the energy system is three solar ionization reactors.

The control system is an artificial brain with primary intelligence, and the power system consists of 4 first-stage warp engines as the main engine and 6 smaller ion engines as auxiliary engines.

Although it is not yet possible to jump, Lin Fan combines the principle of the portal with the energy system, which can allow the ship to have a short-distance teleportation function, but it is extremely energy-intensive to launch once, and can only be used as a hole card.

The ship is capable of accommodating a crew of about 250,000 people and a thousand fighters of various types.

In terms of weapons, it has 500 defensive turrets, 3,800 launch ports, including 2,000 ion beam launch ports, 1,000 defensive space missile launch ports, 200 fighter ejection ports, 1.4 armor defense energy level, 500,000 ion beam energy sources in stock, and 10,000 missiles of various types.

It can be said that this ship has gathered all Lin Fan's hard work and wisdom, and it is the most advanced ship he can build with his current knowledge.

In order to build this spaceship, the accumulation of four years in the industrial area has been exhausted, although there is no shortage of ordinary mineral deposits and rare metals on this planet, but some precious alchemy materials are gone, so it is impossible to make another identical one.

Today, it was the day when the ship named the Galaxy by Lin Fan took off, and around the square where the Galaxy docked, a large number of people gathered, among which most of them, except for the upper echelons of Rogge City, were members of the Night Elf Clan.

"Master Van Lin, are you really leaving?"

Mrs. Leo looked at Lin Fan with a complicated face, the reason why Rogue City can have today's achievements is completely due to him, although he knew four years ago that he would not stay here forever, but when it came to this day, he felt empty in his heart, and it was very unpleasant.

"Well, I don't belong to this planet in the first place, but don't worry, there are still five of those eight apprentices who are willing to stay, with them, and the permission I gave you, Rogge City will only get stronger and stronger, maybe by the time I come back next time, you will have unified the entire planet." Lin Fan quipped.

"My lord, if you have time, you must come back here to have a look, we will always remember you."

In the past four years, both Geraint and Grahide have married, and although they have vowed to follow Lin Fan, they will not leave their planet with him, after all, they have their family and friends on this planet.

"Don't worry, I'll be back when I have the chance." Lin Fan patted the shoulders of the two.

"Teacher, I'm sorry." The five apprentices who had chosen to stay looked at Lin Fan with shame on their faces.

"No need to apologize, you made the right choice, this is your home, and I would make the same choice as you."

Lin Fan looked at the five people deeply, then turned around and walked towards the Night Elf Clan, there are not many Night Goblin clansmen, the whole clan only has a population of about 150,000, although they have a long lifespan, their fertility is extremely low.

"Queen, let's get on board."

"Okay, this is the star map we promised." The queen handed Lin Fan a translucent crystal ball and taught him how to use the star map.

After all the crew members boarded the "Galaxy", in the command room at the top of the Milky Way, Lin Fan glanced down again, and then said lightly: "The secondary engine is ignited!" Set sail! ”

"Yes, Captain!" The sweet synthesized voice of Zhi Brain sounded all around.

Then, a pale blue flame erupted from the bottom of the Milky Way, slowly leaving the ground.

In just a few seconds, the galaxy had reached the planet's atmosphere, and its speed was increasing, and the air near its shell was slightly reddened by the huge friction.

It's getting faster and faster, and after a minute,

When completely detached from the planet's gravity, the main engine in the tail of the Galaxy spewed out powerful blue flames, and began to accelerate at a terrifying speed, faster and faster.

"The auxiliary engine is turned off, the main engine is turned on, and the current speed is 300 kilometers per second, 1,000 kilometers per second, and 10,000 kilometers per second······"

It has been increased to 390,000 kilometers per second before it has stabilized, and this speed has exceeded the speed of light, because the level of Lin Fan's warp speed engine is only 1.3, so the maximum speed of the engine is 1.3 times the speed of light.

This speed seems to be very fast, and at this speed, it will only take about a few minutes to fly from Earth to Mars.

However, when Lin Fan opened the star map, he found that if he wanted to return to Earth with this 1.3-level warp engine alone, it would be a fool's dream.
