The old man Tony is talking about is his father, Howard Stark, who perfectly replicated Dr. Erkins' Super Soldier Serum in '91. This is a good thing that Hydra spent I don't know how much manpower and material resources did not make, and it was perfectly copied by Howard Stark alone, although in the end Howard died and the serum was also robbed by Hydra, but it is not an exaggeration to say that this scientific research achievement can be said to be the first in the world!

But Tony Stark is different, he is proficient in mechanical technology, human mechanics, etc. Although she spent a night reading nuclear physics before going to the aircraft carrier, this kind of intelligence is also rare on earth. But Tony still can't compare to his father.

At the time of Avengers 2, Tony made his Stark Building the headquarters of the Avengers. He'd been working with Dr. Banner for so long, and according to Tony's personality, he wouldn't hurt Banner's self-esteem and secretly study his blood, but there's no reason why Tony, who has Dr. Banner's hair and saliva, wouldn't collect and study it. But in the end, nothing was studied, and Veronica Anti-Hulk armor was created instead.

It shows that Tony has very little knowledge of biology or gamma rays, at least not worse than his old son, Howard Stark.

"Don't you use guinea pigs to do research? Must use a wolf and a crocodile? Tony looked at the two peak beast body test subjects in front of him and complained incredulously.

"It's a jackal, the Egyptian kind." Liu Lei looked at the very nervous jackal in front of him, and couldn't help touching its head to calm it down.

"What about this crocodile? Did you steal such a small crocodile from the time he was still an eggshell? Tony looked at the quiet and young crocodile in Liu Lei's hand and complained.

"This is a juvenile Nile crocodile, I found it in one of the only two intact crocodile eggs I found in an abandoned crocodile nest. This one, named Thorton, was the first crocodile to hatch, a big boy, and another showed signs of hatching this morning. Liu Lei touched the little crocodile lying quietly on his hand, he was present when the crocodile was just born, and according to the creature's imprint, the little crocodile regarded Liu Lei as his mother.

And Liu Lei's reason for doing this is very simple, he wants to create Suodon in the Super Divine Academy, not only that, but also the dog head that should exist in the original worldview, Nasus!

"Why do you have to use crocodiles and ...... Wolf? Can't these clone warriors work? Tony asked, confused.

"It's not that he doesn't use it, it's that I don't let it." Bruce Banner wiped the non-existent dust on his hands and said slowly: "In nature, the human body is backward. And those beasts, insects, and plants, although they have not evolved like humans, have a complete law, social order, or even scientific development. However, their own evolution in different directions has different advantages in corresponding aspects, and the name of this genetic data happens to be the animal body, so I propose to try it. ”

Hearing Banner's explanation, Tony propped his chin and nodded.

"Although the explanation is far-fetched, it should be good, I will meet the earth first, and I wish you success before that." Tony clapped his hands and stood up, intending to leave.

"Hey Tony." At the moment when Tony turned around, Liu Lei spoke.

"What's wrong?" Tony stood at the door and looked at Liu Lei, looking very puzzled.

"Get that stuff out of your jacket pocket." Liu Lei looked at Tony speechlessly and said.

"......" Tony Stark.

"......" Bruce Banner.

……

"What is this? New drinks? Why do you care so much? Banner stepped forward and glanced at a bottle of liquid emitting a golden glow in Liu Lei's hand and asked suspiciously.

"Don't underestimate this thing, if ordinary people are not careful, they will be burned to ashes!" Liu Lei shook the bottle of liquid in his hand and said, Dr. Banner was stunned and hurriedly dodged. He was afraid that Hulk would sense danger and run out and make a mess of it, but this was a good place he had managed to find, and he didn't want to run around.

Although he didn't understand what Liu Lei meant, Banner didn't continue to ask, but lowered his head and continued to work.

And what Liu Lei has in his hand is his last prize in the past two years, the sun light gene of the Heavenly Dao Burning Sun Civilization!

It's a complete gene!

Liu Lei was directly excited and fainted when he drew this opportunity, but until now Liu Lei didn't have the courage to use it, because there are great conditions for this!

Although the system said that paying for a few crossing cards could allow Liu Lei to use it completely, Liu Lei had been pondering.

He wasn't sure if he wanted to implant the Sunlight gene, after all, it was the most powerful super gene in the world of the Super Divine Academy!

"System, can I get the stellar energy drive in it like the original Nova God of War gene?" Liu Lei asked before implantation.

"Yes, extract unnecessary impurities, strengthen the stellar energy control in the fighting genes, and obtain the stellar energy control in the sun's light!" The system replied.

"That's good, by the way, will you have abilities like Rena's flare bombing?" Liu Lei asked suspiciously.

"Yes, these are just one of the stellar energy controls. There is no difference. The system explained.

"That's good, that's good." Liu Lei patted his chest and exhaled.

The gene implantation went smoothly, and there was no explosion of high-heat energy as Liu Lei imagined, causing a natural disaster, just a few energy lightning flashes, although the fusion was successful.

"Is that so?" Liu Lei used the knowledge he had learned to successfully absorb part of the energy of the nearest star and gather it in the palm of his hand.

Looking at the ball of light in his hand, Liu Lei nodded, very similar to when Rena in the male soldier company showed off her "divine power" to Zhao Xin.

Waving his hand to remove this mass of energy, Liu Lei frowned. He felt slightly more severe fatigue.

This is a hidden ability in the genes, which can be used by pouring in and calculating dark energy. Whether it is the ability to fly or clone carried by the fighting gene itself, it is all done by using dark energy. However, theoretically speaking, Liu Lei's current strength of the first-generation divine body, let alone gathering light balls, is more than enough even for a miniature flare bombardment. However, Liu Lei's body has a very serious feeling of fatigue, which belongs to the feeling of excessive use of dark energy!

"In the original book, Rena seems to have the energy of a star injected by an old sun god in her body. It should be the energy of this star that allowed Rena to endure the penetrating wound in the abdomen during the Battle of Tianhe. Liu Lei pondered and continued to whisper: "Should I also try to absorb the energy of a whole star?" ”
