When Leping arrives at Dr. Gro's studio with Trunks and Piccolo, it is dusk near the Arctic Circle.

Dr. Gro, who discovered the arrival of three powerful forces, had already greeted him at the entrance of the cave in advance with his assistant Sanpang.

Tech nerds are raunchy. They can be isolated in the studio for months or even years, obsessed with all kinds of formula experiments, and treat eating, drinking, and lazar as a burden, suppressed to the point of mere physiological necessity. Even eating, drinking, and lazing are considered a burden, let alone dressing up.

But since they all came out to greet (Leping has a lot of face ^-^), then the appearance still needs to be tidied up. Even so, Dr. Groh and his assistant Sanfat classmates are also in a very sluggish state.

I haven't seen him for a while, this guy looks a lot older, his beard has grown a lot, the wrinkles on his face are getting deeper and deeper, and his hair is messy, like a kennel - and slowly, didn't you say that you have tidied up your appearance?

Looking at the body as well: probably in the midst of intense work, the overalls of the doctor and his assistant were stained with oil and dirty—but the parts that weren't stained with oil were shiny white, which proved that the clothes hadn't been changed for long, and that they had probably been put on today.

"That's ...... Dr. Groh?"

Floating in the sky, looking at the skinny old man below who was looking up at him, Trunks' heart fluctuated. In his time, when he was sensible, Dr. Groh was already a dead man, so he hadn't actually met Dr. Gro. At this moment, I saw this father of artificial man, a scientific madman who single-handedly turned the future world into hell, and he couldn't help but have a special feeling in his heart.

Feeling that Trunks' aura began to fluctuate strangely, Leping hurriedly said, "Don't get excited, he's not Dr. Gro from your side. How we treat him is our business. ”

"......" Trunks' breath gradually subsided.

"Long time no see. After stabilizing Trunks, Leping landed in the studio's cave first, "Dr. Gro, why are you so sloppy today?"

"I've always been like this," Dr. Groh said lightly, "Mr. Leping, the first few times you saw me, it was actually not normal. ”

After taking a few steps closer, Leping smelled a sour smell of sweat coming to his nose, and couldn't help frowning, wanting to retreat. Then he suddenly asked himself: can't he even stand the slightest smell? Compared to Bactrian...... Oh, how do you remember that guy who never bathed came?

"This is ......" Dr. Groh looked at Trunks, a little puzzled: this guy has a lot of energy, why doesn't he have information about him in his database?

"Oh, he's a guest from afar - you didn't spy a few months ago when we fought Frieza and the gang, didn't you?"

“...... Can't you use words like 'watching the battle'?" Dr. Groh can only be helpless for Leping's 'uneducated' old man.

“...... I said, old doctor, can't you just take it easy? I always make the atmosphere so serious, you're not tired, I'm tired," Leping was also helpless about Dr. Gro's "old-fashionedness", "Okay, no jokes, you can roughly equate this kid with Frieza - secretly tell you, he can kill Frieza in seconds." ”

Dr. Groh couldn't help but look at Trunks: "What's the matter with this guy?"

Trunks couldn't help but look at these two people: How did these two guys act like old friends?

Piccolo patted Trunks on the shoulder: "Don't be surprised, this is their tradition of Turtle Immortal Flow, when they are not fighting, they are in harmony with everyone, even if they always hold back and slap their opponents to death - but to be honest, I think he did a good job." ”

"That's right, this Ge...... Ge ......" Leping looked at the three fat classmates and began to think about it, but he just couldn't remember the name.

"Colonel Gödern. Dr. Groh reminded.

"Oh, yes, why is he here?" Leping wondered.

"It's not because of the battle you fought with Frieza that we picked up a lot of good stuff and are still working on it. After Dr. Groh finished speaking, he asked, "Then Mr. Leping, what do you have to teach you when you come here today?"

"It's nothing, just to see the progress of your android development - let this friend refer to it. ”

Dr. Groh looked at Trunks for a few more moments, but in the end he didn't say anything, letting a few uninvited guests out of the lab.

"We've found some wreckage of machines in Yunzebit, probably left over from your battle with Frieza—"

Leping thought about it for a while, and roughly understood that what Dr. Groh was talking about was the Frieza ship that had been captured in Giampa and later destroyed by Frieza.

"- Very powerful spaceship, very powerful technology, especially some of the materials on that ship, and that kind of ...... Well, let's call it a 'gun', and the kind of radar you once showed me, Mr. Leping...... It has to be said that solved our big problem. ”

As he spoke, he reached the workshop, where 16 was still lying half-dead on the workbench, half of which was already skinned, and half of the metal skeleton and internal structure were exposed. It's still the same sentence: Although I can't understand everything, I know it is very powerful at a glance.

"With those things, the attack output system, the energy detection system is basically no problem - but it brings a new problem, the energy output method is very good, but with the materials on the earth, it is not easy to make. ”

Trunks frowned: although this is a half-finished product, the general outline can already be seen, but it is just ...... Where is there such a 16th? 17th and 18th?

Just as he was about to ask, Leping spoke first: "I can roughly understand the materials and technology I can get, but that kind of gun and radar ......" Speaking of this, Leping reacted, "It is estimated that it is in the spaceship warehouse." ”

(At that time, a lot of them were found in the spaceship warehouse, Bulma took some for research, and threw the rest on the spaceship)

"Slowly, slowly, I've always been in Yunzebit Heights, how come I don't know anyone has passed?" Piccolo wondered, "Thousands of kilometers around, except for Wukong, I only felt that there was an explorer who went up, and that guy arrived about four hundred kilometers away from where I lived, and then went back." ”

"I guess it's some kind of technical means, such as a spy robot or something. Leping explained, "You have to know that this Dr. Gro is a genius scientist who is not inferior to Bulma. ”

Piccolo was in awe – compare Bulma to Bulma, which can basically be considered omnipotent.
