Now is not the time to confront the annihilation fleet head-on, and it is better to avoid a battle than to avoid it.

A few hours later, as nothing was found, the annihilation fleet left, and the reconnaissance drone sent back footage of the fleet making space jumps.

Although the Annihilation Fleet is gone, the Mech Legion is still building traps, which may be used again in the future.

Refuge.

Xilingchen returned with the team.

The dark red star spirit has been handed over to the mechanical legion, and now all Xiling Chen can do is wait and improve his combat effectiveness, and when he comes back, he finds the little goddess who is repairing the mirror space.

The little goddess seemed to be sitting on the seventh floor of the mirror space in a daze, and when she saw Xiling Chen coming, she immediately asked, "Brother, what's wrong with you?" ”

"How? Can it be fixed? Xi Lingchen asked with a smile.

"Of course you can!" The little goddess clenched her little fists and said, her ontology is learning in the core of the rules, so the current situation is that she is studying how to repair the mirror space while studying.

There is nothing wrong with opening the mirror space, but how to clean up the annihilation absorbed by the Vault is a big problem.

It can't be as originally designed by the goddess.

Change required!

Because the goddess originally left her own power to purify and annihilate, but the divine power of this mirror space has long been exhausted.

The wisdom of the mechanical legion and the little goddess came up with the solution of building a large purification device in the mirror space, part of the area is used for monster farming, and part of the area directly purifies the annihilation power.

The idea is correct, the biggest problem at the moment is energy.

The mirror space in the lower level is okay, and after level 100, the purification device cannot completely purify the annihilation power, because the energy is not enough.

So now, the direction of the little goddess's research is how to solve the energy problem.

There are two types of energy currently used by the Mechanical Legion, one is Void Energy and the other is Dark Energy, Void Energy is the energy used with the Void Engine, but unfortunately, the biggest problem with this energy source is that it can only be used on Void Facilities.

Other devices are not supported.

As for the Void Facility, at present, the Mechanical Legion only has the Void Engine, the Void Energy Cannon and the Void Isolation Energy Network, except for the Void Energy Cannon, which can be used for defense, the other two can't help at all.

As for dark energy, it is more troublesome, although the mechanical legion can build dark energy collectors, but dark energy cannot continuously charge the purification system.

The little goddess told Xilingchen about the current situation, and Xilingchen was also stunned.

To be honest, he doesn't know much about this aspect, but some people do, that is Qingxue and Yue'er, Qingxue is a super artificial intelligence with chaos crystals, and Yue'er is a top-level mechanical life in ancient times, as soon as the two of them heard it, they studied Qingxue a little and said: "What about using stars?" ”

"I've thought about it, but the construction period is too long, and the intelligent system of the Mechanical Legion says that it will take a lot of resources to build a stellar energy harvester." The little goddess said.

Xi Lingchen asked at this time: "Is there any black technology that uses stellar energy in the core of the rules?" ”

After hearing this, the little goddess scratched her head and said: "Yes, there is, but none of them are suitable, one of the simplest problems is a kind of stellar energy collector, which requires a crystal nucleus or gem matrix of more than one hundred and fifty levels, but the mechanical legion has not found a resource area of this level at present, and there are demonic beasts above one hundred and fifty levels, but the mechanical legion said that you can't beat it." ”

"It's true that the one hundred and fifty can't beat it, but the one hundred and forty should be fine." Xilingchen said.

"I want to think about ......"

After the little goddess finished speaking, she thought about it, and on the body of the rule core, she also asked the mechanical legion about the technology of transforming the Warcraft crystal nucleus.

Xilingchen saw that the little goddess was in a daze, and could only wait silently.

Fortunately, it didn't take long, only two minutes, and the little goddess patted her head and said, "Found it, there is a way!" ”

"What's the solution?"

"Solve the problem one by one, the current problem is that there are no materials to build an energy collector, and I can use the technology recorded in the core of the rules, and then cooperate with the mechanical legion to search for the high-level annihilation units within the scope of the shelter, and then teleport the high-level annihilation units to the shelter in a single item, and the one hundred and fifty level is not that we can't beat it, then only the one hundred and forty and one hundred and thirty levels will be transmitted, so that the monster killing and exploding materials can also be upgraded by the way, but ......"

"But what?" Xi Lingchen asked nervously.

The little goddess frowned and said, "But only if I learn how to use the vault to teleport the designated annihilation unit alone......"

"Uh...... Don't worry, you learn slowly......" Seeing this, Xilingchen could only say so.

Who knew that the little goddess immediately shook her head after hearing this: "No, I still have to save my mother!" It works! Give me a few days, I'm going to retreat and study, brother, you gather people, and when the time comes, you can fight monsters! ”

"Okay......"

If you want to open a higher level of mirror space, you need to collect materials first, and to collect materials, you need to fight monsters.

Scratching his head, Xiling Chen could only say: "Qingxue, let's contact someone, call all those who can participate in the battle, the unit of level one hundred and forty is estimated to form a group to fight." ”

……

Again, just like at the beginning, gather the elite forces in your hands to upgrade.

First of all, the manpower on Xilingchen's side, Xilingchen, Yue'er, the Elven Empress, the Pegasus Knights, the Rabbit Spirit, the Guardian and the doppelganger Lily, these are the manpower that can be mobilized at present, of course, there are also blood Lori Jing'er, Starlight Magic Bead, etc.

In fact, there are top powerhouses above level one hundred and forty in the base, that is, Trina, the queen of the Moon Spirit Clan, and May Windsor, the commander of the First Legion, but both of them have to sit in the mirror space on the other side of the base, so they can't get over at all.

If you want to gather an elite force, you can only improve slowly.

Time passed day by day, everything was normal in each base, and Xilingchen was also gathering manpower, and the strong people under his command basically came over.

The maid team, the Pegasus Knights, several princesses, a Sea Emperor team led by Situ Bai Ning, and the rest are Su Miao'er and others, who were not idle after they were assembled, first entered the low-level mirror space defense, and by the way, the mechanical legion upgraded everyone's mechas.

All of them are promoted to Void Mechas, and the powerful ones are promoted to Psionic Mechas.

In addition to these, the Mech Corps has created a batch of special drones to suppress high-level annihilation units that have been teleported, and if something unexpected happens, they will use drones to suppress firepower.

In short, it is necessary to think about everything comprehensively, and there must be no surprises when fighting against high-level annihilation units.

The next thing is to wait for the learning results of the little goddess.
