Toulon Star Field.

Two battleships, one large and one small, stood in parallel, the larger one was the Kong-class battleship, which was jointly responsible for Luo Ying, Zoro, Marta, Hiero, and Carson, and the smaller one was the Princess.

"Later, as we did before, I'll draw firepower for you, and all you have to do is get into the passage as quickly as possible! Don't worry about anything else! Li Yi said loudly to Luo Ying in the communication system.

When facing a large number of mutant beasts, it is most effective to turn on manual operation, unlike Li Yi who controls the Princess alone, the five best battleship operators of the rangers except Li Yi gather on the King Kong-class battleship to control together!

After all, Li Yi alone is equivalent to a squadron, and Luo Ying can't compare with them.

Rumble~

After instructing her teammates, the Princess opened fire violently, attacking the white cosmic pipes.

Swish~

Just like last time, thousands of ninth-level mutant beasts were ejected from the pipeline! One by one, they grinned, and their shapes were extremely terrifying.

The difference from the last time is that Li Yi now has experience in dealing with the enemy, and he found through observation and calculation that due to the high rate of fire, the place closest to the white pipe will form a hollow area, which is the opportunity left for himself!

If it weren't for his full certainty, Li Yi wouldn't have let Luo Ying and them drive a battleship here, after all, the battleship was two levels larger than Li Yi's Princess, and its actions were relatively slow.

"Accelerate! Hasten! Hasten! Li Yi shouted at Luo Ying and them for the first time, and at the same time manipulated the Princess to escort the side of the King Kong-class battleship, interspersed at high speed to attract the attention of those mutant beasts.

Most of the mutant beasts were attacking Li Yi, but it was a King Kong-level with a bigger head that rushed in first, and then saw Li Yi pull the joystick in reverse. As he fired, he followed behind the King Kong in a backward manner, so close that it was as if two ships had become one.

Bang~

With the closure of the cosmic channel, it was pitch black all around, and Li Yi and the others had already entered the interior of this system that controlled the ten star fields!

"Ulla!"

"We're really alive!"

The fighters cheered enthusiastically. Li Yi let out a long breath and lit a cigarette for himself, as if he was not as happy as the Rangers, because he knew very well that although he had entered the demon brain, the real challenge had just begun.

The responsibility of the rangers is great, and only after the rangers have defeated the demon brain center, can the army of the exorcist clan enter it, if Li Yi can't complete this difficult task. I can only watch the Ten Emperor Star Domain fall into the hands of the Ghost Clan!

"Forward!" Li Yi waved his hand and said loudly.

……

A few days later, inside the Demon Brain.

The two figures were hurrying at high speed, it was Hebei Yuan and Li Yi, both of them were wearing miniature propulsion devices and possessing terrifying speeds.

I have to say that the propulsion backpack produced by prehistoric humans is really powerful, and Li Yi feels that he is even faster than the speed of light, when cornering at high speed. That feeling of galloping made Li Yi feel like a dream.

He Beiyuan listened to it in the communication headset for a while. Waving his hand, Li Yi stopped at the corner in front of him.

I saw that several warriors had already gathered here, Li Yi had not seen them before, presumably he Beiyuan had summoned them from somewhere else.

"How's it going?" He Beiyuan asked in a deep voice.

One of the warriors said, "There's not much movement, we've been staying here since we got your message, and every two hours a team will pass through to clear monsters." ”

"What about your people?"

"It's all in the back. According to what you said, the ambush is ready. ”

He Beiyuan nodded slightly, signaling that Li Yi should say something at this time, Li Yi said in a low voice: "You have worked hard, you should already know the situation." Due to the obstruction of the Demon Brain, the army of the Exorcist Clan is outside, but it can't enter, so we have to defeat the command system of the Demon Brain and let our army in. ”

"This prehistoric human arsenal is the first step, first of all, we have to replenish the propulsion backpack, there are enough propulsion backpacks, we can move forward at high speed inside the demon brain without hindrance, so, this battle is not beautiful, it is directly related to the entire war! Everyone, do your best! ”

The warriors were very excited to hear it, the exorcists were coming, and they wanted to clean up the situation, which was something they had been waiting for for a long time!

Li Yi said, everyone geared up, and their eyes gradually revealed murderous aura!

"Three minutes to go." One of the fighters said, looking down at his watch.

As a result, everyone began to stand against the wall, keeping a fixed distance from each other.

Soon, a team of clean-up monsters came out of the inside of this passage, not very tall, about three meters, with twelve tentacles, like walking octopuses.

They flew out of the tunnel, their long tentacles trailing behind them.

Swish~

The number of monsters cleaned up by this team was about 10,000, and they moved very fast, passing in front of Li Yi and them in just one minute, and since Li Yi and they had already prepared, they were not discovered.

Li Yi nodded lightly and said, "I'm going to go in with Hebeiyuan now, remember, only when we have a gathering signal can the large army gather here, understand?" ”

"Understood!"

"Just look at it!"

……

Li Yi and He Beiyuan explained the situation outside, and then they entered the last passage at high speed, as long as they walked through here, it was the legendary ancient arsenal, which contained the propulsion backpack that Li Yi needed very much, and there were complete drawings and production lines.

The Kongo-class battleships and the Princess were too large to be easily spotted by the monsters, and now both ships were moored in the secret base of the Crane Beiyuan, and the rangers and the warriors who stayed behind to guard the Ten Emperors were all relying on backpacks to get here on foot.

It's one thing to hike on Earth, it's another to hike in this vast universe, and it's impossible to do it without the help of a backpack.

Once you put on this individual propulsion system, you have the ability to make micro-jumps.

The essence of the jump is to find two nodes in space, build a wormhole between the nodes, and cross a long distance as long as you pass through the wormhole.

And the principle of micro-jump is the same, but the node selection is shorter, a soldier wears a propulsion backpack and flies in the air, if you shoot it with a high-speed camera, slow motion playback, you will clearly see that it is not flying, but a jump! It's like jumping in the air, suddenly appearing here and there the next, much faster than a large jump engine.

In the simplest comparison, it takes a month for a battleship to cross the Toulon space, and twenty months with a propulsion backpack.

Don't look at the speed, the propulsion backpack is twenty times slower than the traditional jump, but it's a real individual weapon!

With this thing, even if a warrior doesn't even have a battleship, he can still cross the vast star field, but the speed is much slower and the risk is much higher.

After passing through this passage, the front suddenly opened up, and I saw that this was a separate hidden space, and the huge metal planet in the center was the arsenal of prehistoric humans, and the clean-up monsters flew in space one by one.

Each team of cleanup monsters is composed of about 10,000 monsters, and there are about a million cleanup monsters in the entire hidden space, far more than the number of rangers.

"When we first came in, there weren't so many of them, probably to prevent us from breaking in again, and the Demon Brain has deployed heavy troops here." He Beiyuan gritted his teeth and said.

Li Yi nodded and said, "The enemies are relatively scattered, you need to gather them together, and then kill them in one go!" Inform our people, assemble! ”

Swish~

Every two hours, a team of roving Cleanup Monsters leaves or returns, and just as a team of Patrol Monsters enters the hidden space, the Rangers appear.

Due to the lack of propulsion backpacks, the soldiers left behind in the Ten Emperor Star Domain had to drag a dozen or even dozens of rangers forward alone, fortunately, these warriors all had dark arms, and they had a lot of strength, and it was not much of a problem to pull a dozen companions, but the advance speed was a little slower.

The patrol had just passed, and for two hours the rangers were safe, and they approached behind the patrol, and when they were about a dozen kilometers from the entrance, they all stopped.

"Send a signal to Li Yi, we are ready!" Lin Feng said in a deep voice, and at the same time stretched out his hand to the back and pulled out his murder weapon.

And Li Yi, who was signaled by Lin Feng, raised his hand lightly and released the Southern Cross from the fugue.

Swish~

Like a swarm of bats in the dark, the remnants flew up and then collided with each other, making harsh sounds and dazzling sparks.

Those clean-up monsters saw the strange situation here, so they hurried over, and seeing that they were already approaching, the Southern Cross suddenly stopped attacking each other, but rushed directly like sharp arrows!

Puff~

Puff~

After all, the Southern Cross is a divine soldier, not afraid of pain, nor afraid of being caught, just use your strength to cut it!

And those clean-up monsters let out screams because they couldn't bear the pain, attracting more mutant beasts to help!

It's like a swarm of hornets in space, they are stupidly attacking around Li Yi's Southern Cross!

Li Yi's bait tactics are done!

"Brothers, come on!" Li Yi said in a deep voice in the communicator.

The rangers who received the order and the warriors who stayed behind in the Ten Emperor Star Domain rushed in, the third battalion of the rangers lined up at the entrance, and the others directly joined the battle to clean up the monsters!

"Undead Ranger!"

"Fight to the end!"

Finally, the loud slogan of the Ranger Legion exploded in the Ten Emperors Star Domain!

Li Yi's tactics are very simple, this is a hidden space, and it does not belong to the demon brain system!

As long as they can't leave this space, they can't pass the signal out of the city, and if they can't pass the signal out of the city, there will be no reinforcements!

Li Yi looked at the timing system on his wrist, there was still one hour and thirteen minutes before the next patrol came and went, that is to say, the rangers needed to complete the battle within an hour! (To be continued......)
