Terrarim Cluster, Wormhole Sector 0358.

There are blue-black wormholes in this area, large or small, tearing at the space, the space-time coordinate coefficient is constantly floating, and a small spaceship is carefully passing through this unstable space, which is Han Xiao's car.

The central area of the Broken Star Ring is a large group of wormholes, belonging to the territory of the Terrarim Star Cluster, this dangerous area is called the wormhole area, there are few human tracks, only a few major star cluster-level civilizations have stationed people here, established wormhole observation stations, and divided the wormhole area into hundreds or thousands of sectors.

The central wormhole area of the Broken Star Ring connects many corners of the universe, and the wormhole observatory is working to measure the position of some wormholes connected to the other end, but due to the extreme instability of wormhole swarms, old wormholes often disappear and new wormholes are born, so the measurement progress is slow.

According to official data, only 1 in 2.4 million wormholes have been measured to date.

Han Xiao's destination is the observation station of the wormhole sector 0358, and the publisher of the level 180 silver inheritance blueprint task is the mechanic who maintains this wormhole observatory.

Passing through a wormhole area, a small space station appeared in the field of vision, surrounded by wormholes, Han Xiao pressed the spacecraft operation board, sent a landing request to the space station, and soon got permission, and then drove the spacecraft to dock with the space station, enter the port passage, the bottom of the spacecraft and the magnetic orbit click tower were chimerated, and glided in the narrow passage for a while, and then suddenly opened up and entered the dock.

Stepping off the spaceship, Han Xiao greeted the maintenance staff at the dock.

"Lord Blackstar, you're looking for Professor Harrowfar again?" The maintenance staff responded with a smile.

"Well, where is he now?" Han Xiao nodded.

"You just happened to be here, Professor Harofal went out with the survey team to collect wormhole parameters some time ago, and he only came back two days ago, and now he is stuffy in the research room doing experiments."

"Thank you." Han Xiao smiled, walked away from the dock, and drove to the research room of the wormhole observatory.

This wormhole observatory is not the property of Crent or Amethyst, but belongs to another cluster-level civilization of the Broken Star Ring, which has not intervened in secret wars and is semi-neutral.

Harofal is a scientific research mechanic, not good at fighting, is a professor-level figure in an official mechanical college of this cluster-level civilization, has been at the forefront of technology, researching various topics, in order to study wormhole swarms, take the initiative to apply for the maintenance of the observatory, at the same time, he is also the publisher of the drawing task.

Han Xiao had already completed the drawing task in the seventh ring, and this observation station had been here several times, and the personnel here were already familiar with him.

Unhindered came to the research room, Han Xiao reported his identity through the access control, waited outside the door for a while, the door of the research room opened, Harofar walked out, glared at Han Xiao, and said angrily: "It's you again, you bothered me to do the experiment." ”

"Experiments can be done at any time, and I don't see them all the time." Han Xiao laughed.

Harofal was an old man, with a purple complexion, gray hair and beard, very old, but his back was very straight, and he looked stronger than a young man, an old man.

For the Department of Mechanics, knowledge is power, Harofal has a deep study of various mechanical theories, and is also highly talented in the Department of Mechanics, and has been immersed for many years, it is normal to become an A-level mechanic, but Harofal has always been committed to the study of technology and rarely fights with people.

Although his level is not low, he has many sub-classes like [Scholar], and his combat power is at the bottom of the A-level.

A galaxy-level civilization has dozens of official A-level superpowers, and the number of A-level superpowers in the cluster level civilization is naturally dozens of times more, after Han Xiao entered the catastrophic level, he usually basically dealt with people of the same level, and it seemed that there were many natural calamity-level, in fact, compared to the huge number of B-level and C-level superpowers, the absolute number of natural calamity-level was still very small, and it was very rare in the sea of stars.

The so-called talk and laughter are confucian, and there is no white ding, people at the same level will often come and go, and people below the natural disaster level will find it difficult to see the natural disaster level.

There are relatively many A-level superpowers in cluster-level civilizations, and they can afford to raise some talents who don't need to fight, such as Harofal, who has low combat effectiveness and specializes in scientific research.

Although Harofal was engaged in research, he also knew that Black Star was also a master of machinery, and there was still basic respect, so he temporarily put down his research and invited Han Xiao to the reception room to chat.

After chatting for a while, Han Xiao brought the topic back to the drawing task, this silver inheritance drawing is Harofal's private property, Han Xiao reached an agreement with him early, as long as he helps him do something, Harofal is willing to teach the drawings to Han Xiao, and now the task has reached the seventh ring.

Harofal thought for a moment and said his request, and a prompt sounded on Han Xiao's panel.

He glanced at the new part of the drawing task, the task was not difficult, but it was tedious.

Han Xiao did not delay, ended the chat, said goodbye to Harofal, acted resolutely, left the observation post, and immediately went to do the task.

There are a total of ten rings in the level 180 silver blueprint task, which is basically no danger for Han Xiao today, and it only takes time to complete.

In the next half month, Han Xiao ran around, constantly going back and forth to the observation station, concentrating on completing one task after another, this time Lever gave him a long vacation, and he had plenty of time.

On the way to do the task, I didn't encounter any unexpected troubles, and it went very smoothly. After more than ten days, the drawing task in the task list was finally displayed as "completed", and Han Xiao immediately returned to the observation post and found Harofar to hand over the task.

Harofal took Han Xiao to his private room, rummaged through the cabinets, found a square mechanical safe, entered his own mechanical strength as the unlocking code, and the mechanical component of the safe moved, like a Rubik's cube turning, and after a while, the safe clicked open.

Harofal reached out, took out a thick stack of mechanical drawings, shook it, and placed it on the table.

"Okay, according to the agreement, this drawing is yours, it's really strange, you have been busy fighting in the past few years, and you have to take time out to help me with things, could it be that this drawing has any particularly important role for you?"

"Sort of." Han Xiao nodded.

Seeing that Han Xiao didn't say anything, Harofar didn't ask, flipped through the drawings on the table, and said: "This is what you want, I also got it from someone else, it's not a secret, although it's an interesting technology, it's not very advanced, it seems to be a drawing handed down by an ancient mechanic." ”

"I'll take a look first."

Han Xiao glanced at ten lines, quickly skimmed the drawings, and the reading progress popped up on the panel, his intelligence attribute was extremely high, so his reading speed was very fast.

In just a few tens of seconds, this complex drawing was read again, with the existence of panels, as long as his intelligence was high enough, he could learn a drawing hundreds of times faster than a regular mechanic.

Harofal next to him thought that Han Xiao was just looking at the goods once, but he didn't know that in just a few tens of seconds, Han Xiao had already mastered the knowledge of this drawing.

[You gain ["Glacier Frozen Star*** Paper] x1]

[You have learned a new skill [Blueprint - Glacier Frozen Star Cannon]!] ]

It's finally here...... Han Xiao let out a sigh and looked at the drawings on the panel.

Inheritance drawings generally have the exclusive name of the middle two, and the Ice Frozen Star Cannon is a level 180 machine, a strategic weapon belonging to the planet strike level, and it is the equipment of the gunsmith, and it can also be used as a mechanic.

Most of the energy cannons are red-hot high-energy particle streams, and the glacier frozen star cannon is extremely cold, and the drawing introduction says that if the glacier frozen star cannon is raised to the highest power, it can lead the planet's climate with one cannon and let it enter the ice age, although the destructive power is not as good as the serious star destroyer cannon, but it is also an extremely powerful weapon.

Maybe it's because the Ice River Frozen Star ** paper is relatively old, and it is relatively easy in terms of knowledge requirements, in the cutting-edge knowledge, you only need to master the [Abnormal Energy] and the [Controllable Annihilation Weapon], both of which happen to be in Han Xiao's knowledge base, but there is no need to find new cutting-edge knowledge.

"Hmm, this Frozen Star Cannon needs a lot of rare materials, and it looks like it will have to go back to make it."

Glancing at the cost, Han Xiao secretly said, the cost of this giant cannon is probably more expensive than a serious Star Destroyer cannon.

Technology was developed to create high-powered weapons at as low cost as possible, and older drawings were basically very powerful and more expensive, after all, the technology at that time was not as elaborate as later generations.

However, can a problem that can be solved with money? If you have a mine at home, you can do whatever you want!

Rich! Wayward!

Putting away the drawings, Han Xiao nodded and said, "There is no problem with the things, then I'll go." ”

"Why don't you stay and chat before leaving, I still want to talk to you about technology."

"No, I still have something to do."

"Alas, okay, I'll take you to the dock, and if you're free in the future, you can talk to me at any time, you have my communication number."

Harofal felt a pity, he still liked to chat with Han Xiao, both of them were mechanical masters, and the topic couldn't be finished.

However, as soon as he left the room, the lights in the hallway suddenly changed to bright red warning lights, and the cacophony of sirens echoed throughout the observation station.

Buzz Buzz –

"Enemy Attack Alert! Enemy Attack Alert! ”

Harofal's face changed drastically, and before he could speak, a violent shock swept through the entire observatory, and Harofal almost stumbled.

Immediately afterward, a series of deafening explosions came from afar.

Thundered!

The surging flames spread rapidly down the corridor, like a fire dragon passing through, and the corridor was filled with flames and rushed towards the two of them.

Han Xiao frowned, the nanoparticles clinged to his palm, turned into arm armor, twisted his backhand, opened a gradient blue oval ghost energy shield, easily blocked the flames outside, and then turned his head to look at Harofal.

"The enemy must be bombing outside, leave the observation post first."

Harofal had little experience with the enemy, but he was not so flustered, he unfolded his mecha, smashed the corridor at once, broke through the outer armor of the observation station and flew out, Han Xiao activated the mountain ape mecha and followed out.

The two of them left the observation post, and only then did they see what was happening, and their faces suddenly changed.

I saw a fleet surrounding the observation post from all sides, not to mention 500 warships, and gathered fire towards the observation post, the protective shield was torn apart almost instantly, and continuous high-energy ion beams penetrated the observation post, turning it into a hornet's nest.

The next moment the fire swelled, and the observation post burst into parts.

"Oops, my lab!" Harofal's face changed suddenly, and he gritted his teeth and screamed, full of heartache.

"Damn, my ship!" Han Xiao's eyelids twitched.

The Black Light Stalker was driven back by Renard, he was only piloting an ordinary small spaceship this time, but Han Xiao also stored some barracks boxes on it, if it was blown up, it would be a loss - although he was not short of money, it was shameful to waste!

Han Xiao raised his hand and made a move, and the space beside him fluctuated, and one by one the barracks boxes jumped in, and after counting them, he couldn't help but breathe a sigh of relief.

The shell of the barracks box has different damage, but the compression ball inside is fine, in addition to the jump device installed on the barracks box, there is also a protective cover function, which was originally to prevent the enemy from attacking the barracks box, but at this time it came in handy, blocking the aftermath of the explosion at the observation station.

The entire Observatory was a cloud of cosmic garbage, with only a handful of superpowers surviving, and the attack was so sudden that the personnel of the Observatory did not react at all.

Because it is a space station for scientific research, the defense measures here are limited, after all, few people will deliberately attack the wormhole observatory set up here by a cluster-level civilization, and this is also a wormhole area, and the unstable wormhole group is a natural line of defense, and almost no one will fight here.

"Who is this group of people and why are they attacking us?" Harofar was furious.

I don't know...... Han Xiao was also very curious, he intuitively felt that this group of enemies was coming at him, and it had almost become a habit to be assassinated in the past few years.

He frowned and looked around the fleet, and was about to speak, when the mech suddenly received a message.

"See you again at last, Blackstar!"

This voice is a little familiar!

Han Xiao's eyes flashed and he looked over.

His gaze crossed a piece of cosmic space and locked on a figure that had emerged from the fleet, and after seeing this person's appearance clearly, Han Xiao was secretly shocked and quite surprised.

This man is an old enemy who has been missing for several years, the leader of the dark star!

How did it come to this place?!
