Jiang Han withdrew to the steel defense line with this group of workers.

On the way, they also have the responsibility to protect this group of people.

Of course, those strange beasts encountered in the middle were also low-level strange beasts, and they were solved by someone from another team without Jiang Han's action at all.

In order to complete the task of killing thousands of people, Jiang Han cleaned up the entire mining area and the strange beasts around the mining area, so that the people in this team were like these miners, they were not in any danger, and they didn't even encounter any trouble, and they made the money for this mission while lying down, and they were naturally very grateful to Jiang Han in their hearts.

On the way back now, they should always do something, otherwise it would be a bit too much.

Jiang Han didn't know what they were thinking, he just put his hands behind his back and followed the team slowly, while in his hand, he rubbed a thunderball in his hand.

This is the method that Jiang Han figured out by himself.

Condense a ball of thunder in your hand, and then use your mental power to communicate and control, increasing your control over the thunder element.

The effect of this method is visible to the naked eye and useful.

At least Jiang Han's current control of the Thunder Element is far from being as immature as it was when he first awakened.

The thunder converged in Jiang Han's palm, but it seemed extremely calm, even if two currents occasionally spread to other places, they were still within a controllable range.

For the current Jiang Han, improvement is even progress.

Before the college entrance examination, if the thunder he summoned does not get out of control, it is a success.

Because with a team of miners, Jiang Han and his party were not moving fast.

How fast can a group of miners whose strength has not yet reached the martial arts level increase their speed?

At this rate, it would take at least seven or eight hours to get to the steel line.

Not to mention carrying a bunch of mining equipment.

Fortunately, Jiang Han was not in a hurry, and after the construction was completed ahead of schedule, there was plenty of time left for him.

Throwing the thunderball ball out of his hand, killing a high-level beast soldier who tried to sneak attack, Jiang Han secretly estimated the damage of this thunderball in his heart.

This thunderball was within the range of his complete control, and it was not a full explosion.

If Jiang Han exploded with all his strength, the power of the thunderball he had saved would at least double the power of the thunderball.

It's just that in this way, Jiang Han needs to throw this thunderball out in a very short time, so as not to let the thunderball get out of control and affect himself.

And the high-level beast soldiers can't withstand a blow under this thunderball, which means that the thunderball that Jiang Han has saved with all his strength has at least the damage of killing the junior beast general in seconds and seriously injuring the intermediate beast general.

That's enough.

Thunder is still only level 1, and Jiang Han's control of Thunder has not yet reached the point of mastery, being able to have this damage is enough for him to be pleasantly surprised.

For the rest of the night, by the time the engineering team returned to the steel line, it was already dawn.

Jiang Han didn't rush back, he first sold the beast materials that were taken from the corpses of the alien beasts in the system space, and then found a place to take a bath.

This was the longest time he had been in the wasteland, for more than ten days, making Jiang Han only feel the smell of sweat all over his body.

Although I found a small reservoir to wash once, how can cold water be as comfortable as hot water soaking?

After taking a bath, I had another meal, and then took the city train back to Lan City.

After returning the 45 million that they borrowed from Uncle Long, Jiang Han still had more than 883 million in his account, of which 8 million were supplemented by Jiang Han's later sale of alien beast materials.

I went to pay the personal income tax on the mining income, and there was still 495 million left.

It's enough for Jiang Han to spend.

There are still two days left before the college entrance examination, and Jiang Han has no plans to go to the wasteland again, and it will be the same when the college entrance examination is over.

Xiaobai is still hunting strange beasts in the wasteland, look at the panel, this little guy is already level eight, and his combat power has successfully exceeded 10,000.

This upgrade speed is not much slower than Jiang Han.

What's more important is that the stronger Xiaobai's strength, the more strange beasts he can hunt, and the more experience he shares with Jiang Han every day.

Stable experience provides the machine, and Jiang Han feels that he should be kind to Xiaobai.

After all, after binding Xiaobai, except for the first two days, Xiaobai has been free-range by Jiang Han.

can't help but give him no care, Xiaobai has to work hard to help him farm monsters to gain experience.

"Why don't you buy tens of millions of metal for it before you go to the wasteland next time?"

Jiang Han, who has money in his pocket, has a lot of confidence in thinking about things now.

But that's all after the college entrance examination, and there is no need to think about these now.

Two days passed in a flash, during which Jiang Han had been nesting on the second floor of the restaurant, trying to figure out how to control the thunder.

And now, the college entrance examination is finally about to begin.

According to the past practice, the college entrance examination will first take cultural courses, and then the combat strength assessment, a total of five days.

And Jiang Han's cultural test center is in his own school.

Before the catastrophe, the college entrance examination was one of the greatest opportunities for students to change their lives, and the same is true after the catastrophe.

The level of college you enter represents how many job opportunities you have after graduation.

The only difference, though.

Colleges and universities after the catastrophe are different from those before the catastrophe.

There are colleges and universities that specialize in training scientific researchers, universities that train technical staff, and naturally there are universities that only have martial artists in the whole school.

Compared with before the catastrophe, the teaching direction of colleges and universities at this time was very single and more professional.

Unlike before the catastrophe, one university had multiple majors.

It's like the water and wood that Jiang Zhiyu entered, after the catastrophe, it became the only top-notch martial arts school in the Celestial Empire, and the teachers were all Wuhou.

Parallel to this, there are only military forces with national backgrounds, but the military military does not recruit students, and only selects talented and highly qualified soldiers from the army.

So for ordinary people, Mizuki is still the only one.

As for scientific research, Kyoto University took over the teachers before Mizuki and became the only one in the country.

Mizuki and Kyoda, one article and one martial arts.

Originally, according to Jiang Han's homeroom teacher, Jiang Han had no talent in martial arts, but with the stable top three results in the whole school, it was still possible to enter Beijing University.

But now......

When choosing between Mizuki and Jingda, Jiang Han still prefers Mizuki, not only because Jiang Zhiyu is in Mizuki, but also because of the system.

"Lao Jiang."

"Didn't Uncle Jiang come to accompany the exam?"

Jiang Han was wearing casual clothes, shirts, shoes, and slacks, and when he walked into the school gate alone, he was patted on the shoulder.

When I looked at it, I realized that it was Chang Hao.

In the distance, Chang Hao's parents were waving to greet him, and Jiang Han also smiled and beckoned, which was counted as a response.

"No, my dad has a long trip and hasn't come back yet."

Speaking of his father, he has been out for almost a month, and even if he goes out in the past, it is rare that he will not come home for such a long time.

Jiang Han called him, but the other end of the phone reminded that his father was not in the service area at all.
