Before going to the 2186th plane of the machine, Lu Wei first recorded the time when the earth was located.

Mobile time: 7:38

Leave your phone on your computer desk and wear a mechanical Rolex watch on your wrist.

Then pick up the plane shuttle mark, press your thumb, and appear in the main control hall of the base.

Kai was repairing the base, Lu Wei didn't bother him, and after staring at the mechanical watch for an hour, he picked up the plane shuttle mark and returned to his bedroom.

I looked at the phone on the computer desk and showed the time: 8:15

"An hour has passed on the base side, and only 37 minutes have passed on the Earth side, and the time flow ratio is about 1.62:1......"

Lu Wei is a semi-science fiction fan, and has a certain amount of research on Einstein's theory of relativity and Schörvatz's superstring theory.

The theory of relativity explains the relationship between time and gravity and speed, while the superstring theory directly compares time to a beating string, sometimes fast and sometimes slow.

For two completely different planes, it is certain that the speed of time flows is different, and Lu Wei was aware of this from the beginning.

He was glad that the time of the machine 2186 plane was slightly faster, and even if he stayed there for a longer time, it would not seriously affect the daily life on this side of the earth.

……

"Ding Ding Ding Ding, Ding Ding Ding, Ding."

It's the Angry Birds ringtone, and the phone is calling.

Lu Wei picked up his mobile phone, and the caller ID was from Chen Long.

Swipe to answer, and there is a loud noise on the other end of the phone, mixed with DJ music and real people singing.

"Brother, come here, I'll introduce a beautiful woman to you." The voice on the phone was loud, the tone was not very coherent, and it seemed that he had drunk too much.

"I have something to do, so I won't go today."

"What's the matter, come here, Feng Shao wants to play two games with us, one thousand and one games, isn't this giving us money? Come on, come on, come on. ”

"There's really something, I can't go, let's go again tomorrow."

"Disappointed...... Well, if you don't come, forget it. ”

After hanging up the phone, Lu Wei shook his head, just now he heard a few coquettish voices from the phone, and he knew that Chen Long's guy was hugging left and right again.

Lu Wei and Chen Long have a good relationship, Lu Wei is three months older than Chen Long, and he is considered an elder brother.

Twenty years ago, Lu Wei and Chen Long's parents worked in the same state-owned enterprise and lived in the same staff building, and the relationship between their parents was like that of iron buddies and sisters.

If the relationship between the parents is good, the relationship between the children is naturally good.

In kindergarten, elementary school, junior high school, high school, and even university, Lu Wei and Chen Long are all classmates.

When I was a child, we were naughty and mischievous, we fought with classmates together in middle school, and we played games and chased girls together in college...... It can be said that they are inseparable, and the relationship is like a brother.

Chen Long's family background is good and rich, much better than Lu Wei's family.

In fact, the starting point of the two families is exactly the same, after the restructuring of state-owned enterprises in the 90s, Chen Long and Lu Wei's parents were laid off and went to the sea to start a business.

Chen Long's parents are more bold, go to the south to look for opportunities, more than ten years, they have supported a huge family business, there is a company with assets of more than one billion, not to mention, there are many hotels, restaurants, stores and other fixed assets, in S City, there is also a very famous Shenglong KTV.

Compared with Chen Long's family, Lu Wei's family is a little dwarfed, Lu Wei's parents are timid, they have always been in a small business, and it is very remarkable to earn 500,000 yuan a year, and they can only be regarded as petty bourgeois.

How much money does the Chen Long family have? Lu Wei and his parents have also often discussed, and have come to the conclusion of at least 500 million yuan, but they are also very confused, at the same starting point, why is the gap between the two families so big?

In this regard, Chen Long once explained at the dinner table: "Uncle and aunt are still too stable, these days, how can you make money without spending money?" How can you make a fortune if you don't invest your old money? My parents' business has not failed, and they have wanted to jump off the building several times, but they haven't survived yet? The greater the risk, the greater the reward. ”

Lu Wei's parents were thoughtful, but they still didn't dare to learn the Chen family's way of doing business, the risk was indeed too great.

On the day of the funeral of Lu Wei's parents, Chen Long's family was crying, Chen Long's parents pulled Lu Wei and said that he would be their son, Lu Wei was very moved, but he politely refused.

……

The plane shuttle mark can only be used back and forth twice a day, and today's two times are used up, Lu Wei himself is also a little tired, and after washing up, he went to bed.

10 a.m. the next day.

Lu Wei went to the base, and Kai told him that the repair progress of the base had reached 58%.

After lunch, playing games for half an afternoon, and staying up a little anxiously until 10 o'clock in the evening, Lu Wei estimated that it was almost there, and then came to the base again.

"Kai, has the base been repaired?"

"It's done, it's about to start."

"Oh, that's great." Lu Wei's spirit was shocked.

Kai begins to activate the various systems in the base.

"Activating the Power System ......"

The headlights of the dome in the base lit up one after another, illuminating the base as bright as day.

"Library Open ......"

Resource Center Open ......

"The ...... of the scientific research center is opened"

"The systems of the base have been activated! Turning on the Energy Harvesting System ......"

Through the camera lens, Lu Wei saw that the giant pot lid on the top of the base yesterday shrunk into a metal ball, and after two days of repair, it is now like a bud blooming, and it has become a brand-new pot lid with a shiny metal surface.

"The energy collector is deployed, the energy harvesting system is activated, and the energy collection ...... begins"

A humming sound emanates from the energy center, and a turbine spins beneath the base.

Driven by the turbine, an invisible suction force is generated above the base "pot lid", and the dispersed free energy begins to gather and concentrate in the center of the pot lid.

The free energy in the enriched state will emit a bright white light when it is gathered together.

Lu Wei saw that a faint white light slowly appeared at the top of the energy center, like an axis of light, running through the core.

Buzz.

With the addition of additional energy, the power of the turbine increases, making a louder noise.

Kai breathed a sigh of relief: "The base is starting to operate normally, and in two days, the energy core will be generated." ”

Lu Wei also breathed a sigh of relief, looking at the energy center through the glass wall of the main control hall, and his heart was slightly excited.

Somewhat different from the game "Defensive Formation", Lu Wei's task in the game is to protect the energy core from being stolen by aliens.

But this real tower defense base can produce the energy cores needed by the production base.

His job is to maintain the continuity of this production.

"By the way, I forgot an important thing, I haven't activated the tower system yet."

"Tower System Activation ......"

After Kai finished speaking, Lu Wei saw that on the defensive platform inside the base, a large number of gray squares, one after another, first opened the top cover of the square, and then a tower-shaped object rose from the square.

The tower-like object is a rectangular column, with a bottom surface of one and a half meters long and wide, and a height of about three meters.

This debugging defense tower, after rising from one gray square, and then lowering from the gray square, forty-eight gray squares, one by one, was debugged.

"The tower system is intact, and the base has been repaired."

"Kai, now that the tower system is intact, can we build a tower right away?" Lu Wei asked excitedly.

"Not yet, the resource center is currently under-resourced."

Kay opens a stats table that shows the amount of inventory resources.

――

【Resource Center】

Energy core: 0

Normal Resources: 36

Special Resources: 0

Towers: 0/48

――

It takes 100 units to build a machine gun tower, and the remaining resources are not enough to build a machine gun tower.

"With such few resources, if monsters come in, how can we resist them?" Lu Wei asked.

"Don't worry about this, there is also a resource collector under the base, which can absorb about 5 units of ordinary resources from the soil and rocks per hour, and the material reserves in the resource center will slowly increase."

There is a set of mineral element precipitation devices under the tower defense base, which can extract various resources needed to build the base from the soil.

Kai added, "If the base has enough energy cores, the resource collector will absorb resources faster, so there is no need to worry about resources." ”

Lu Wei also found a problem, in the resource center, in addition to ordinary resources, there is also a column of special resources.

What is a special resource?

"Special resources are rare elements that are difficult for the base to extract from the nearby soil, but they are key to upgrading towers, developing new tower species, and improving base technology...... These are inseparable from special resources. ”

"How can I get special resources?"

"The monsters that invade the base will more or less contain some special resources, and they are the main source of special resources for the base."

Lu Wei suddenly realized: "So that's the case, the monster invasion can also bring some benefits to the base!" ”

Kay shrugged: "So to speak. ”

……

Another day passed.

When Lu Wei came to the base again, Kai told him an exciting good news: the energy center was about to condense the first energy core.

"Great!"

Lu Wei asked Kai to point the lens at the energy center, and was very excited to see that with the continuous convergence and compression of free energy, in the middle of the optical axis of the energy center, a gradually solidified energy core slowly took shape, increased, and emitted a light blue fluorescence.

When the energy core condensed to the size of an adult's fist, under the impetus of an invisible repulsion, the energy core ran to the side of the optical axis and began to do an irregular rotational motion...... The blue energy core, like a crystal gem in a dream, exudes an incomparable charm.

The first energy nucleus, formed.

The data in the Resource Center has also changed.

――

【Resource Center】

Energy Core: 1

Normal Resources: 306

Special Resources: 0

Towers: 0/48

――

Lu Wei stared at it for a long time, and smiled happily: "Okay, haha, great." ”

Kai's face changed slightly, "The gate of the base has found traces of monsters and is attacking the gate. ”
