"Sir, you have been in the laboratory for a day."

When Fang Yan was busy in the laboratory of the Donnager battleship, Jarvis' voice suddenly sounded.

"fine."

Fang Yan shook his head and suddenly asked, "Jarvis, how is the earth's vibrating gold reserves, is it enough to make a spaceship?"

"Sir, we haven't stored enough for the time being. Since Miss Clomentina already needs to update the equipment on Earth, our vibration gold reserves will not increase but decrease."

Hearing this, Fang Yan's brows slightly wrinkled. The vibranium is all his urgently needed items, and he has been planning to store more vibranium to make the full version of the Donnager battleship. If you want to make a reduced version, it is better to use The one in front of me was made of ordinary metal compression.

"Develop a few more planets as soon as possible recently. There are 6 planets in the solar system minus Earth and Mars. Start with these planets as soon as possible."

"Okay, sir."

Jarvis responded.

"Ok."

Fang Yan nodded slightly, then stared at the blob of scarlet blood in front of him, frowning nervously: "I didn't expect that the production of serum is still a bit difficult..."

"Hulk serum! If it is made, it will definitely be stronger than Zhenjin Iron Man."

"Unfortunately, there are still a few difficulties to overcome."

Fang Yan shook his head slightly. He was very eager for the Hulk serum. If nothing else, the fact that Hulk dented the Zhenjin shield with one punch was enough to make people excited.

It's just that the side effects are also a bit obvious. One is confusion. Of course, if you make a reduced version of the Hulk serum, it's still possible, at least you can keep your senses, just like a female Hulk.

A weakenable serum was never what Fang Yan wanted.

"Forget it, let's continue the experiment."

Fang Yan emptied the blood in the petri dish, and then took out a new blood sample. The serum samples stored in the Donnager battleship were all drawn from the warriors of the Tuxiu Mutu star. For this experiment.

There are many technologies in the head, but it only provides the production method, and the optimization method still needs to be pondered by Fang Yan. Although the perfect superhuman serum is powerful, it is only the enhancement of ordinary people, while the Hulk serum is an all-round enhancement. Even the defense is comparable to vibranium.

"The reason why I can transform into a Hulk seems to be through the radiation of gamma rays..."

Fang Yan touched his chin, looked at the blood in front of him, shook his head, and muttered to himself, "It's just that I have tried many times, and these blood cells eventually die, and none of them are alive or mutated."

"However, I must remove the side effects of the mutation..."

Fang Yan smiled bitterly. This kind of difficulty is really not that big. To make Hulk serum, all you need is some blood and gamma rays. As for the next step to remove side effects, you need to finish the first step.

"It's stuck at the first step now."

Staring at the blood on the table, Fang Yan fell into deep thought. Originally, the blood of people from Tuxiu Mutu was very suitable for studying the mutation of serum.

"The blood of the Tuxiu Mutu star people is not good, is it possible to use my blood?"

Looking at his arm, Fang Yan's mouth twitched slightly. If only his blood can make the Hulk serum in the future, wouldn't he have to draw blood every time, and he needs to draw a lot?

"If I let my whole body go in and radiate, then the risk is a little big."

The manufacturing method in the head does not require gamma rays to directly irradiate the human body, only some mutated blood, but the reason why Hulk is Hulk is because his whole person was irradiated by gamma rays, and finally became the Hulk.

The current production method is somewhat conflicting, but Fang Yan still prefers to choose the production method in his head. After all, gamma rays directly irradiate the human body, and all that is seen is luck. If you are lucky, you may succeed and become an irrational Hulk. Of course he fell to the ground and died.

"I really don't know how these superheroes survived."

Thinking of the difficulty of his own production, Fang Yan couldn't help complaining. After complaining, he continued to work hard. When he ran out of materials, he asked Jarvis to send the Iron Man to the warriors' rest room to extract it.

When the next day dawned, the warriors of the entire Fangshen Heavenly Kingdom had been devastated by Fang Yan, they had not slept all night, and their blood had been pumped again and again.

This made them wonder, why did they join the Fangshen Heavenly Kingdom? Didn't you say you were going to take them out? Why is it now the subject of research?

"I don't know what the King is doing. I slept well last night, but I was woken up by Iron Man in the middle of the night and delivered 500 milliliters of blood directly..."

"Me too! You've only been drawn once, and I've been drawn twice, a liter of blood! How much do I need to eat to make up for it!"

On this day, the warriors complained and wailed all over the place. It is a pity that those Iron Man only obeyed Jarvis' orders, and Jarvis obeyed Fang Yan's orders, and Fang Yan was busy in the laboratory. Their wailing could not be heard.

"Strange, what went wrong again?"

After a night of experiments, I failed more than a thousand times, but the blood still did not change, and there was no change in the slightest.

"Where did it go wrong?"

Fang Yan squeezed his chin, constantly recalling the memories in his head, overlapping the steps with those he had completed.

But after the comparison, he found that the experiment he did did not go wrong, but the experiment was right, so what went wrong?

"Put the blood into the petri dish first, and then turn on the intensity of the gamma rays to the maximum."

When Fang Yan pressed the gamma ray transmitter, he quickly put on the mask on his head, and his eyes were instantly pitch black.

After that, a ray of light that was ten thousand times more dazzling than the sun appeared, and even the outer wall with a thickness of fifty centimeters could not resist the strong light, so it spread out.

This is the outer wall compressed by Fang Yan, and even it can't resist the strong light of gamma rays. It can be seen how much Fang Yan has turned on the gamma rays.

Fortunately, Fang Yan's mask is made of vibranium combined with other metals, so no light can be revealed. Even the vibranium version of the steel battle suit he wears uses vibranium and other metals.

"Failed again..."

The strong light gradually weakened to the point where it could be tried. Immediately, the petri dish was quickly taken out.
