However, Anwen did not integrate all the backbone technologies.

In that case, he might as well directly produce the engine of the other world, why bother with this effort.

Eliminated the fusion connections of many technology icons, and only kept the connection lines related to the engineering structure.

"Do you spend 6 million survival points to integrate backbone technology and improve the structural performance of the monster engine?"

"Sure."

A white light flashed.

An Wen is not surprised by this, the monster's engine is much worse than the epic engine.

Looking at the optimized monster engine design, its internal structure is more scientific, the volume is reduced by a quarter, the weight is reduced by 820 kg, and the thrust-to-weight ratio is increased by 1.5.

The previous monster engine was completely based on the performance of the material.

"After a while, I'm giving them this blueprint, so that they can absorb and digest it when they design the second-generation engine."

Anwen closes the tech tree list and returns to the villa.

╭(╯^╰)╮

When the disc saw An Wen, he directly tilted his head, indicating that it was still angry.

"Send you back to watch cartoons, but you can't spoil things anymore, otherwise...... You know. ”

An Wen pointed to the roller coaster in the distance and said to the disc.

Of course, the disc was aggrieved, but An Wen didn't bother to pay attention to it and sent it home directly.

Ever since the disc started watching cartoons, it has become a drama spirit.

Back in the other world, An Wen put on his equipment and let 9527 drive the electromagnetic guardian mecha to the underground transportation hub.

Originally, An Wen wanted to clear the big boss in the depths of the mine, but after thinking about it, he decided to let it go.

Let that big boss live for a while longer.

After all, the Zerg attacking the city every day can bring Anwen more than 50 billion survival points of income.

If he destroys the big boss in the depths of the mine, without the Zerg attacking the city, his daily income will be reduced, thanks to this.

Mosquito legs are also meat, not to mention the income of more than 50 billion survival points, which is no longer mosquito legs, it is elbows.

And there is another point, that is, An Wen is not sure whether the game version will be updated after destroying the big boss in the depths of the mine.

So, to be on the safe side, let's go to the next wave of dungeons first.

Board the transport ship.

"Go to Resource Point 9."

"Okay, Commander."

9527 takes control of the transport ship, enters the isolation chamber, and then enters the vacuum pipe, and spends fast to Resource Point 9.

In less than ten minutes, the transport ship entered the isolation chamber at Resource Point 9.

"Commander, please choose the path forward?"

At this time, a virtual screen appeared in front of An Wen's eyes, giving three options.

The first option is to access a warehouse that says 100 tons of helium-3 and 30 tons of biological material can be obtained.

The second option is to access a small resource room with 1,000 tons of helium-three, 300 tons of biomaterial, and a piece of biocrystal.

The third option is to access the Resource Refining Center at the bottom of the resource point, which states that you can obtain 5,000 tons of helium-3, 800 tons of biomaterials, and 5 biocrystals.

When An Wen saw this, he didn't know that this was the difficulty of choosing a dungeon.

The first option is easy difficulty, the second is hard, and the third is hell.

Don't think about it, just click on it.

He didn't know what was going on in the dungeon, so of course he had to choose the easy difficulty to study.

When An Wen finished choosing, the door of the isolation chamber opened.

"9527, go."

"Okay, Commander."

The Electromagnetic Guardian leaves the isolation pod and enters the resource point lobby.

“…… The Zerg of the copy is different, so reckless. ”

As soon as they left the isolation pod, a bunch of Zerg rushed towards the electromagnetic guardian mecha like crazy.

Whoosh ......

A dozen small missiles sent these zergs directly to meet their masters.

The electromagnetic guardian mecha swept all the way, and there was no need for An Wen to make a move.

"Worker bees, jumping insects, puppies, stinging snakes, ......"

An Wen looked at these Zerg who kept rushing up, and kept naming them, because these Zerg looked a little familiar to him.

Although they are different from the ones in the game, some of them have something in common.

In less than ten minutes, An Wen came to the door of the warehouse.

"I don't know what kind of boss is here."

Airplanes......

The doors gradually opened.

Whoosh ......

Swift black shadows rushed out of the warehouse.

Because the distance was too close, before An Wen could react, he used a weapon to attack.

The shadows slammed into the electromagnetic barrier.

The next second.

A huge burst of fire, accompanied by a roar and shock wave, directly bombarded the electromagnetic barrier.

"It's ...... Bug bombs? ”

Although he was overwhelmed by the explosion of the self-detonating Zerg, An Wen did not panic at all.

The shield value of the electromagnetic barrier did not drop much at this moment, and it was safe for him to sit in the mecha.

"Sure enough, with the upgrade of the technology tree, there will also be various corresponding classes on the Zerg side, which will shoot lasers and self-detonate, maybe I will encounter nuclear bomb worms in the future."

An Wen listened to the constant roar and muttered quietly.

This is also his krypton, if he is replaced by an ordinary player, this wave will definitely lose a lot.

The roar of the explosion lasted for five minutes.

When the roar of the explosion stopped and the fire in front of him disappeared, An Wen saw the image of the boss in the warehouse.

This is a Zerg boss that is a bit like a praying mantis, but does not have a mantis belly, but has a scorpion lower body.

It is very large, two circles larger than the electromagnetic guardian mecha.

When the Electromagnetic Guardian Mecha stepped into the warehouse, the boss showed a noble purple-gold health bar, and it also leaned down and lay on the ground to charge power.

"Is this a skill?"

After An Wen saw the BOSS's posture lying on the ground, he immediately opened the electromagnetic guardian mecha hatch and aimed at the boss with the gaze of the Grim Reaper.

Aim for the dead spot, lock, shoot!

Bang!

The moment the bullet is fired, the boss also completes the skill charge.

As soon as the boss's skill was activated, the bullet hit its dead spot.

The direct death verdict takes effect.

-10000000

Health bar empty.

The corpse of the boss remained in the state of activating the skill, and I saw it rush towards the mecha at a teleportation speed, and then fell to the ground in front of the mecha.

"Moving graves flashed? Thousands of miles of flying corpses? ”

An Wen looked at the corpse of the boss and said with a smile.

Fighting the boss or something, it's all trivial, the most important thing is to see what the boss explodes.

"9527, go down and see if there's anything on the Zerg corpse." An Wen said to 9527.

"Okay, Commander."

9527 quickly ran to the boss's corpse and began to scan it continuously.

An Wen, on the other hand, entered the warehouse and looked at the beehives that were full of honeycombs in the warehouse.

Inside these boxes are nuclear fusion fuel, helium-three.
