The next night, Fang Zhengguo really brought a person as promised, dressed plainly, bent over, it is really a very rare old man now, there is no change, the level is extremely low, and even the things on his body are not even a thing that can be regarded as equipment.

"Is this an old antique? Are you sure you're looking for the wrong person? ”

Wang Yuan could see the situation of this old man at a glance, the poor guy who barely survived hiding on the earth with government subsidies, didn't even have the courage to survive in Tianzhu, this kind of person was the most boring.

"People can't look good, although Lao Chen has retired for a long time, he is a genuine ......"

"Hmph, it's just a little ghost, old Fang, you shouldn't have asked me to come over to see a joke for this little ghost, right?"

Before Fang Zhengguo's words were finished, Lao Chen interrupted directly, and he didn't give a good face, but for the sake of Fang Zhengguo's face, he barely left.

"Of course it's not for this kind of boring thing, my time is not idle to this extent, won't Uncle Fang explain?"

Wang Yuan took a sip of his drink, if he had real talent and real learning, then he didn't mind spending more time, on the contrary, he had to consider whether to choose Fang Zhengguo as a partner.

"Ahem, then let me introduce you first, this is the former director of our weapons research institute, Lao Chen, just call Dr. Chen or Professor Chen, and this is the famous goblin king of Black Rock City, little brother Wang Yuan."

Clearing his throat, Fang Zhengguo introduced separately, Wang Yuan just nodded, and Lao Chen didn't have a surprised expression, he didn't know the name but as soon as he said that the king of the goblins was in this Black Rock City, everyone knew about it.

"Hmph, I didn't expect the rumored Goblin King to be a hairy boy, at this time, you two bigwigs in Black Rock City are looking for the old man, there must be something great to use this old bone."

It seems that Lao Chen has indeed not been strengthened by many heavenly pillars, and he is already too tired to stand for so many minutes, so he found a place to sit down, and ordered a glass of water by himself.

"Lao Chen, your opportunity has come, not long ago, I kept saying that I want to realize the agreement with my family, this time the opportunity has come, use your dusty knowledge."

Fang Zhengguo didn't explain the matter clearly in advance, probably because of secrecy, after Wang Yuan gave him a look, he was silent for a while before he said to Lao Chen in a heavy voice.

"What? Can Earth's technology be used in this place? ”

Lao Chen didn't know where he got the strength to slap the table and stand up, and asked in surprise, a drop of water kept flowing down.

Through Fang Zhengguo's simple explanation, Wang Yuan also knew that the old man's family had all died after today's Tianzhu, and he had not survived the Tianzhu activity because he had already been half buried in the ground.

Such a big blow can be imagined, but the old man did not give up, he once made an agreement with his relatives to work hard to live, and contribute to the country, research more and stronger scientific and technological equipment, weapons.

"Yes, it's not confirmed yet, but it's promising."

Fang Zhengguo nodded, he could understand why Lao Chen was crying, in Lao Chen's heart, he did not have the idea of rewarding his relatives and fighting against fate, but what can an old man who is half-cut into the ground do in this Tianzhu, after the same strengthening as young people, it is only to restore the strength of his youth, and it is even more miserable in the early stage, and it is difficult to walk well.

"In that case, if you need my old bones, use them to your heart's content, no matter what, as long as the old man can do it, I will do my best."

Lao Chen also realized his gaffe, wiped his tears, bent his legs as straight as possible, and his back as straight as possible, so that he could show a little spirit.

"Cut, what is the use of a handful of old bones, Uncle Fang, please go and dig out this old bone in the soil first, otherwise it will not be useful, maybe it will hang up when, and the loss will be great."

Since he is an old acquaintance of Fang Zhengguo, he must be genuine, but the current state is too miserable, and it is a little difficult to walk by himself.

"Don't worry, Lao Chen is also my old friend, even if you don't say it, I can't leave it alone, and besides, there is as much work as the mountain for him to do next, in case the strength is insufficient, it can't be done."

Fang Zhengguo disappeared into the night with Lao Chen, and in the next few days, he would ask the leveling team in charge of the research institute to bring Lao Chen, and even Fang Zhengguo personally led the team and took him to level up.

In the past few days, Wang Yuan released the [Preparatory Knight Battle Soul] every day to study, and then read some information in the void world to learn this knowledge, and at the same time combined his own knowledge.

"It's been a long wait, and it's finally working."

Lao Chen, who brought Fang Zhengguo back, is finally no longer an old bone with a head and teeth that have fallen out, but an uncle in his forties and fifties, similar to Fang Zhengguo, although he will not return to the peak of **, but the most basic physical ability can be guaranteed.

"Hmph, it's really a little uncomfortable to be hairy, but for the sake of the old party's face, I don't care about this, so I hurry up and get down to business."

Lao Chen's rejuvenation is not only physical, but also mentally active, and relatively speaking.

"This contract, the content should already be known, if you accept it, then sign it."

As soon as he grabbed the high-level contract in Wang Yuan's hand, Lao Chen signed his name on it, and then the contract turned into sporadic points of light and dissipated.

"Ding: Do you teach the [Mechanical Researcher] sub-profession?"

"Yes!"

With Wang Yuan's choice, the cocoon of rules emerged from the void, of course, everyone else could not see it, only Wang Yuan could see it, and a small ball of light floated out of the cocoon of rules and merged into Lao Chen's body.

"I was told that I got a [Mechanical Researcher] subclass, is that the end of it?"

Lao Chen looked at his body, there was no change, and asked Wang Yuan.

"Yes, that's fine, but it's not possible to craft complex mechanical items yet, and that's tied to the level of the subclass."

In fact, Wang Yuan didn't say it, this has to be linked to the cocoon of rules, it makes no sense to say so much so early, you can only promote this kind of rules and let the cocoon of rules grow quickly to solve the problem.

"Now that today's task has been completed, then I will go back with Lao Chen, and as for dividing it, I will send someone to you."

Fang Zhengguo took out a mask and handed it to Lao Chen, and he changed for a while, and then the two hurriedly disappeared into the night. (To be continued.) )8
