Unlimited career change starting from mechanic

"Here are your medicines for today, and here are the firearms and weapons that you need to repair and recycle this week. In addition..."

Ruin Star, Vault No. 73, the clerk of the management office put a bunch of worn-out firearms on the trailer, and took out a bottle of reagent tubes with amber liquid flowing and handed it to Su Yu. After hesitating, he reminded her more. One sentence.

"Due to the recent expansion of the Night Fury team, the number of anti-radiation potions in the shelter is not enough. This is the third and last bottle of potion. I wish you good luck."

Su Yu rubbed his face vigorously, took the potion from the clerk's hand, and forced a smile: "Thank you, please give me your kind words."

After saying that, he took the trailer and medicine and returned to his repair shop.

"Compared with other fellow time-travelers, my time-traveling life is really a bit ruined..."

After cleaning up the repair room, Su Yu looked at the anti-radiation medicine in his hand and smiled bitterly to himself.

Strictly speaking, he is not a person from this world, but a time traveler from Blue Star.

What he faced after traveling through time was a doomsday wasteland that was countless times crueler than his hometown of Blue Star.

【Ruin Star】.

This is an outpost star set up on the edge of the Milky Way when the human empire was wiping out alien races during the Great Crusade. Its main responsibility was to provide navigation guidance and certain logistical supplies for the human fleet of the Great Crusade in the star sea.

But this is the 40,000th year of the Empire's reign in the galaxy.

The glory of the Great Crusade has long been obliterated by the dust of history. Civil strife and alien races have completely torn the great empire apart. The glory of ruling the Galaxy no longer exists. The outpost stars that once had the beautiful name [Azure] have now become ubiquitous in space. ruins of stars.

The people on this ruined planet are the descendants of the survivors when the Great Crusade ended. Because of the loss of technology and the lack of resources on the ruined planet, they have no hope of leaving this planet.

What awaits them is a short life of struggling to survive in radiation and dust.

Fortunately, I relied on a little bit of luck and the advantage of physically traveling through time.

Although it is suspected that when traveling through time and space, his body has shrunk a lot and returned to the age of eleven or twelve years old.

However, his physical fitness, which had not been affected by too much radiation, and his already excellent learning ability on this star, allowed Su Yu to successfully become a resident of Vault 73 and become an apprentice repairman.

However, just a year ago, the only old man in the shelter who was willing to teach Su Yu how to learn mechanical maintenance skills died of radiation sickness.

Not long after, Su Yu was also unfortunately infected with radiation sickness.

Su Yu looked at his right arm. There, there were already large pieces of muscle tissue eroded by radiation, which turned into a dark purple color, accompanied by waves of fatigue.

Over time, this necrosis will spread throughout his right arm, at which point he will have to have it amputated.

However, compared to many radiation diseases that can be fatal once infected, Su Yu's symptoms are already mild.

But the problem was that for a trainee repairman whose apprenticeship was only half a year longer than two and a half years, Su Yu, who was missing an arm, was obviously no longer qualified for the subsequent repair work.

And shelters never support idle people.

Su Yu, who cannot be a repairman and has no other work experience, will be doubly dangerous in any job he can do. Considering Su Yu's physical condition by then, he may become one of the ruins in less than a year or two. With dry bones.

The only hope is the anti-radiation medicine in front of him.

This is one of the rare perks for shelter residents.

When you are infected with radiation sickness, you can receive one dose per week for up to three weeks. After using three doses, there is about a 10% chance of recovery depending on the type of radiation sickness.

There is still a 20 to 30 percent chance of slowing down the erosion of radiation sickness.

Considering that Su Yu was infected with radiation sickness, his symptoms were relatively mild.

The probability of his recovery may be higher than 10%.

"No matter how bad it is, we can still delay the erosion of radiation sickness!"

Su Yu gritted his teeth.

Although now due to the expansion of the Night Fury team, various material contributions to the shelter have increased.

Anti-radiation agents are also 20% more expensive than before.

But as long as he can give himself a little more time, he can accumulate contributions by repairing firearms for the hunting team in the shelter, and exchange them for new anti-radiation potions.

only.

After finishing a day's work.

Su Yu took out the anti-radiation medicine he received, removed the cork, pointed the reagent tube directly at the necrotic part of his right arm, and fell down hard!

Shelter No. 73 is only a small shelter, and the anti-radiation medicines it possesses are not high-end. They are also very harmful to the human body. They are not suitable for oral administration or soaking the infected area. This crude method of use is the most dangerous. Best way to use it.

"Chichichichi——!"

Just like pouring ice water on burning coals, a large amount of water-white smoke suddenly rose from Su Yu's necrotic tissues, which was accompanied by severe pain. Su Yu couldn't help but clench his teeth, and there were blue veins on his forehead. He stood up violently and sat on the ground with a thud!

Although this was not the first time he had used this medicine, the pain was still a bit unbearable for Su Yu.

It wasn't until half an hour later that the severe pain subsided slightly.

Su Yu put on his clothes again, took out a simple nutritious meal from the old cupboard, and ate the vegetable paste which had no taste and taste and only provided basic calories. After dinner, he couldn't wait to turn off the lights, go to bed, and go to bed. .

It takes one night for the anti-radiation medicine to take effect. What is his fate will not be known until early tomorrow morning.

With expectations for tomorrow, Su Yu fell into sleep.

However, the next morning.

When Su Yu came to the half-broken full-length mirror with anticipation and rolled up his sleeves, the sight that greeted his eyes made Su Yu, who had always been optimistic, completely speechless!

Worst outcome.

The large piece of necrotic muscle tissue on Su Yu's right arm showed no signs of improvement, not even signs of delay.

The necrosis that originally occupied only one-fifth of the arm progressed a little further toward the wrist over the course of one night.

Follow this trend.

In three months at most, Su Yu's right arm muscles will be completely necrotic.

Judging from the feeling of weakness in his right arm now, Su Yu may no longer be able to perform the repairman's job within two months at most.

"Is it possible that my luck in this life has changed because I have practiced so much with guns? But these two guns are not the same thing!"

Su Yu was really on the verge of crying.

But, right now.

Su Yu suddenly noticed that there was something extra on the mirror in front of him.

No.

wrong.

It wasn't that there was something extra on the mirror, but that in his field of vision, as Su Yu concentrated his attention, a blue virtual light screen gradually appeared!
