"Hey......"

Qin Shi's small face turned red, and he struggled to break off a lever that controlled the mechanical arm.

Before that, he had found a barrel of lubricating oil with two-thirds volatilized and lubricated the machinery, otherwise he would not have been able to break the rusty rod.

Qin Shi operated the mechanical arm of pure physical strength, put it on the switch button of the steam kinetic energy tower, and knocked it hard, and after slapping the top lever, the entire maintenance base suddenly trembled.

"Woo ......"

There was a low roar from the kinetic tower, and a cloud of black smoke was expelled from the exhaust pipe next to it, staining the entire space in a black haze.

The smoke of the burning stone, which could not be burned completely, was mixed in the air, and Qin Shi took a deep breath, not feeling unacceptable.

In fact, the ancient continent itself has a strong odor, which is why outsiders like to wear breathing masks on their faces. As an indigenous, Qin Shi has long been accustomed to a worse smell, and the smell of smoke can be regarded as pediatric for him.

"Ahem...... Bah! ”

After spitting out a mouthful of black phlegm, Qin Shi wiped the beads of sweat from his forehead with one hand, and his palm, which was stained with lubricating oil and rust, painted him into a big black face.

"Let's fix this steam hand cannon first!"

When the kinetic energy tower is fully charged, with the power provided by the kinetic energy tower, it is no longer difficult for him to control the robotic arm. Operating the mechanical arm, a 500-kilogram steam hand cannon was quickly pulled onto the repair table.

The steam hand cannon favored by Qin Shi has a history of at least three hundred years. is the most primitive clumsy type. This kind of hand cannon was originally chosen by the most ferocious stormtroopers in the Terran world. It requires at least level 8 Force force to drive it, and when fighting in a position, it is often one team with one, and even the strongest defense line will be bitten by it.

But again, the steam cannon was too bulky, which affected the team's movement speed, and slowly moved from offensive to defensive. But in this regard, the steam hand cannon was not as powerful as the light and heavy force cannon in the real sense, and finally slowly metamorphosed and was finally eliminated.

The reason why Qin Shi chose the steam hand cannon as the maintenance object is very simple. There were a lot of broken steam hand cannons, and he could replace them with the necessary parts. In addition, he has really repaired a lot of machines like this steam hand cannon. I know very well the components inside, this kind of stupid black and coarse thing is very simple to maintain. It can save him a lot of time.

There is also a reason that Qin Shi himself may not have noticed. Not long ago, he saw the hand cannon used by the old cannon, which also made the steam hand cannon have a lot of impression in his heart.

"Yo, the little guy is good......"

I don't know when, the black rabbit appeared on the light screen in Qin Shi's eyes again, watching Qin Shi quickly drag the steam hand cannon to the repair table, and then moved a lot of machinery from under the repair table, picked up the sledgehammer and began to dismantle the broken cover of the steam hand cannon, clean and neat, in one go, and couldn't help but praise Qin Shi.

Qin Shi was in no mood to deal with this mysterious rabbit at this time. From what information is known, he already knows that his situation is extremely dangerous, and if he doesn't accumulate points quickly, he will soon be judged a loser and die a tragic death in this place.

"I said, I'll help you ......"

The rabbit muttered to himself, pacing back and forth under the tree. Qin Shi was quite uncomfortable for a while, and blinked his eyes vigorously.

At this time, Qin Shi had already smashed open the protective shield of the steam hand cannon, he took a deep breath, pulled out a charging line from under the repair table, and docked it into the energy storage box of the hand cannon.

"Click!"

There was a screeching sound from inside the box, and a cloud of black smoke emanated from inside.

Qin Shi hurriedly pulled out the charging cable, with a wry smile on his face.

"There is no such thing as a fluke......"

Qin Shi hoped that there was no problem with the storage box of the hand cannon, so that he could repair the hand cannon quickly. However, it turned out that it was impossible to cut corners here.

"You can't live like this......"

The rabbit gloated in the light screen again, and a small part of the carrot that it had gnawed off was found by it out of nowhere, and stuffed into its cheeks, puffing one by one.

"So what?"

Qin Shi took out a wrench from the ground and began to disassemble the energy storage box. Judging from the reaction of the energy storage tank, the matrix array that converts energy inside should have been damaged, and it is impossible to store and use kinetic energy. In this case, either the matrix array will be replaced, or it will be taken out and adjusted.

There were a lot of steam hand cannons around, but Qin Shi had roughly determined in his heart that it was impossible for him to dismantle an intact matrix, and only by taking it out for repair was the right way.

However, doing so will inevitably consume more time, and it is already luck to be able to repair this steam hand cannon in three hours, don't think about the extra points.

At this point, Qin Shi also had to carefully turn to the rabbit in his mind. Although this guy is mysterious and weird, he doesn't seem to have suffered a big loss except for being tortured in a dream. And after waking up, Qin Shi also carefully deduced the mathematical questions that the rabbit asked.

It's okay not to calculate, but after calculating it, Qin Shi really discovered that that question is not for people! He was quite talented in arithmetic, and Uncle Martin even said that if he was lucky, he might even follow the path of a mental arithmetic in the future.

Once you become a mental arithmetic, it means that you have stepped into the ranks of nobles in this life, and the shipping lanes, industrial production, warship design and maintenance, and even the search for the cosmic tidal channel by the Force masters in the galaxy world are inseparable from the calculations of the mental arithmetic.

However, after repeated confirmation, Qin Shi found that the question given to him by the rabbit, not to mention the ordinary mental arithmetic, even the most powerful divine arithmetic master in the galaxy world, Victor Hugo, couldn't be counted!

Rabbit's question, Qin Shi instinctively knew that the answer was certain.

However, in the field of mathematics, instinct and feeling cannot be used to prove.

It needs to go through the logical reasoning of numbers, and finally arrive at a general calculation method, that is, a basic formula, and anyone can answer this question with the help of a formula in order to prove success.

This means that it takes enough time and perseverance to calculate the general laws of calculation from the infinite number relationships, which requires many calculations...... This is the same result as counting the stars in the universe one by one.

Qin Shi knew that this rabbit was not simple. The guy who can ask the arithmetic of the entire galaxy world a question can imagine how powerful his ability is. And the rabbit seems to have some connection to both the home planet and the city of Sunset, maybe this guy can give him some help.

"The old guy likes to play games the most, so the one he hates the most is my ......"

"Why ......"

Qin Shi waved his hand, it was useless to say this. If this nonsense guy continues like this, he should be pragmatic and quickly get the steam hand cannon ready, he casually said perfunctory.

"Because here, I'm just hanging......"

The rabbit said something that Qin Shi didn't understand at all.
