"Woo woo......" Lele has escaped into Professor Luo's arms, habitually coquettish.

"You little thing, how did you become like this? Boy, it's really you. Professor Luo rubbed Lele's head, no longer doubting Sun Yan's identity.

"You kid, you just like to pretend to be a ghost. Mo Ling laughed, the cross scar on the bridge of her nose was still there, but the sorrow was gone, and she was more and more bold and wild.

Sun Yan smiled and introduced Mu Tong and Kong Ningyan to the two of them, and then Professor Luo directly closed the laboratory temporarily and stayed inside to describe the experience during this time.

It turned out that since the Ling Xixing incident, the members of the Cleaner Camp were resettled by the Chen family, and Professor Luo and Mo Ling went to a free trade planet, and the three of them lived a rare and comfortable life.

During this period, only Ling Zi and Lao Zheng went to visit and talked about Sun Yan's recent affairs.

This time I came to participate in the grand event of Holy Bear City, not long ago, Lao Zheng visited Professor Luo and talked about Sun Yan's recent situation and the damage to the [Heaven and Earth Fearless].

So, Professor Luo came with Mo Ling, wanting to exchange some materials to repair the [Heaven and Earth Fearless].

"You kid, you know what to do, but you do it very well, and you deserve to be a member of our cleaner camp!" Mo Ling rubbed Sun Yan's hair and said with a smile.

Sun Yan's eyebrows danced, boasting to himself, and praising himself fiercely, as if he had returned to the days of Lingxixing, where a group of people gathered together and chatted from all over the world.

Mu Tong and Kong Ningyan listened quietly on the side, they were all hearing Sun Yan's past for the first time, the life of the cleaner was the lowest day, and they were all stunned.

"You bastard, you haven't come to see my old man once until now, hum! Tell you, I know that thing, in the current Odin Star Field, in addition to my old man, it is difficult to find a second person who can repair that thing. Professor Luo raised his head and began to warp.

Sun Yan was surprised and delighted, and hurriedly smiled: "I said Old Man Luo, why do you have to be like a kid and me! I actually wanted to see you for a long time, isn't it that I was in too much danger later, and I was worried about affecting your old man." I'm telling the truth!"

"Cut, to tell you the truth, you kid's mind, I still don't know, you're worried that I'll give you that thing. Professor Luo rolled his eyes and said angrily.

Sun Yan laughed dryly, the reason why he hadn't visited Professor Luo was because he was worried about accepting the [Eternal Energy Core]. This thing is Professor Luo's only concern, if it is handed over to himself for safekeeping, then Professor Luo has nothing to love, and it is likely to commit suicide.

Now it seems that Sun Yan is too worried, I haven't seen him for a while, Professor Luo is in good spirits and looks much tougher, which should be the credit of Mo Ling's sister and brother.

"This old gentleman, he can fix that thing. Mu Tong exclaimed, unbelievable.

You must know that the Yuan Energy Mechanic who can repair the [Heaven and Earth Fearless] is at least the level of a quasi-master, and the number of quasi-Yuan Energy Mechanical Masters in the current Odin Star Field is too small, perhaps more than the quasi-deployment master, but it is definitely a rare existence.

Empty Condensation Yan was also quite surprised, because Professor Luo's appearance was really cold, and he was really thousands of miles different from the mastery of the Quasi-Yuan Energy Mechanical Master.

"Ai, barrel, you don't know what to do. Professor Luo was a master of quasi-Yuan Energy Machinery a long time ago. Sun Yan patted his ass and praised it repeatedly.

However, he was also telling the truth, Professor Luo was already at the level of a quasi-Yuan Energy mechanical master hundreds of years ago. After such a long time, maybe he will already be a real master of Yuan Energy Mechanic.

"Grandpa Luo, you are really wise and powerful, and your aura is extraordinary! Please take my knees. Mu Tong pounced directly and hugged Professor Luo's knees.

"Grandpa Luo, I am Ah Yan's best friend and friend, and the two of us have a lifelong friendship. You are his grandfather, naturally my grandfather, I am a trainee Yuan Neng mechanic, you must always carry me more!" Mu Tong's eyes were eager, and his tone was extremely sincere.

Mu Tong's enthusiasm made Professor Luo a little overwhelmed, but he also saw the relationship between Sun Yan and Mu Tong, and promised again and again that he would definitely guide.

Mo Ling and Kong Ningyan were dumbfounded, but Mo Ling shook his head with a smile: "It is worthy of being Xiao Yan's friend, it is really like a gathering." ”

"Awards, awards!" Sun Yan smiled without any shame.

Immediately, Professor Luo asked about the extent of the damage of the [Heaven and Earth Dreadnought], this is the scene of the exchange meeting, and this legendary fighter cannot be taken out, otherwise, it will definitely cause a sensation and set off boundless waves.

However, Professor Luo's level of Yuan Energy Machinery has indeed reached an extremely deep level, and just by asking about some information, he deduced that the [Heaven and Earth Fearless] has damaged the Yuan Energy Core.

"This thing is not an emperor-level fighter after all, and staying in the space channel for too long will definitely damage the Yuan Energy core. It's a hassle!"

Sun Yan's heart jumped, Professor Luo said that it was very troublesome, and it seemed that it was quite difficult to repair the [Heaven and Earth Fearless].

"If it's just the fuselage and engine of the fighter, it's much easier to repair. If the core of the Yuan Energy Mechanic is damaged, then repairing it is no less than rebuilding a new Yuan Energy Fighter. ”

"Rebuild a ......" Sun Yan looked bitter, he knew how difficult it was.

Seeing that Sun Yan's face was becoming more and more disappointed, Professor Luo changed his words and said with a smile: "What are you bare upset about? I only said that it is difficult, but it is not that it cannot be repaired. The certainty is still quite large, about seventy percent. ”

Mu Tong couldn't help but speak: "Seventy percent! Grandpa Luo, you must be a real master of Yuan Energy Machinery, right?"

If you want to build a Yuan Energy Mechanical Fighter, it is not difficult, but if you want to build an SS-class, or even quasi-emperor-level Yuan Energy Fighter, it must be a real Yuan Energy Machine Master.

Professor Luo smiled slightly, noncommittal, for a scholar like him, this level of certification is dispensable, and he never takes it to heart.

The certification of the master of Yuanneng Machinery, like the master of stock liquid blending, must be recognized by the Zeus chaebol. Of course, this is not only a recognition of reputation and strength, but also a way to buy and exchange for rarer materials and items after obtaining the master qualification certification.

This kind of convenient benefits is what those masters are really interested in, otherwise, with the quirks of many scholars, who would want to participate in that kind of certification examination.

In the case of Sun Yan, he never wanted to participate in the assessment of blenders, and Professor Luo was the same.

"To build a quasi-emperor-level Yuan Energy fighter, I am confident in terms of technique, but it is quite difficult to collect materials. Relying on this event alone, I'm afraid I won't be able to exchange enough materials, and when this event is over, I will go to the Zeus chaebol for master qualification certification. There are channels to buy and exchange the missing materials. ”

Next to him, Mu Tong listened to it with a pleasant heart, and he couldn't stop talking, Professor Luo is the real master's demeanor. When it comes to being certified, it's as simple as eating and drinking.

"Master Certification. Sun Yan's heart moved, he thought of his original liquid naughty qualification, but he had never been certified, whether he wanted to find a time, and he would also be certified and assessed.

Knock knock knock...... The door of the laboratory suddenly roared, and a cold voice came from outside the door: "Open the door! Open the door quickly, what are you doing when you close the door during the exchange and exhibition?"

Sun Yan frowned, his face was cold, if he didn't want his disguised identity to be exposed, he would directly punch out.

During the exchange and exhibition, whether the door is closed or not, this is the freedom of mechanics and blenders, and it is also a kind of respect of the organizer.

"Hmph! Noisy and rude bastard, looking for death. "Empty Condensation Smoke has a chill on his face, and he is presumptuous in front of a true Yuan Energy Machinery Master, even in the Imperial Clan, he will be severely punished.

Professor Luo waved his hand and said, "You young people, why are you so angry? I'm not angry, Xiao Ling, open the door quickly." Maybe it's an exchange of materials. ”

Sun Yan's heart is warm, the purpose of Professor Luo's trip is all for him. Otherwise, with Professor Luo's temper, how could he endure such a thing.

The door to the laboratory opened, and there were three people standing outside, looking rather strange.

The trio had tiled black skin, and their bare arms were covered with metallic armor, as if they were born with scales. Two of them had a strong aura, they were cultivators of the tenth-level martial realm, and the other was in suits and leather shoes, wearing small round-framed glasses, and they looked like scholars.

"Molten Armor. ”

Sun Yan and the others couldn't help but be stunned, the Molten Armor Clan is a second-class civilization very close to the Odin Star Domain, this race has an extraordinary talent in terms of Yuan Energy Machinery, and it can be said that it is a natural Yuan Energy Mechanic.

The scholarly Molten Armor Man glanced around and sneered, "Even an old fellow like you is embarrassed to make such an item exchange list? Do you have these precious materials to exchange?"

Pointing to the light brain screen outside the laboratory wall, Professor Luo listed the list of material exchanges, at least all of which were A-level or above items, including S-class precious materials.

"I don't have to, you don't have to worry about it. You're here to exchange materials, which one?"

For the contempt of this Molten Armor Clan, Professor Luo was a little happy in his heart. The Molten Armor Clan is a second-class civilization, so they may be able to come up with some of the materials they need.

"Old man, in the list you listed, 'Magic Light Stone' and 'Purple Star Fragment', do you really have these two materials? These are S-class rare materials. The Scholar-led Molten Armor Man questioned.

Professor Luo didn't speak, and directly took out a magic light stone and a purple star fragment: "Here, I will exchange 10 pieces of the two materials." ”

Professor Luo is not worried about being robbed, the security here is jointly taken care of by the Zeus Chaebol and the military department, whether it is a high civilization or the power of the Earth Alliance, he does not dare to act rashly.

The two materials exuded a strange brilliance, enveloping Professor Luo's hands, causing the three Molten Armor Clansmen to look straight and almost want to pounce directly.

"I want to exchange and bring me the materials I need. Professor Luo frowned, a little impatient, he sensed that the three of them had no intention of exchanging.
