Dense test tubes and some delicate instruments filled the corner of the room.

A mini display is flashing rapidly with strings of data.

These are all exchanged by Zhou Duan from the local survey.

Equivalent to 100 points.

At this moment, the test tube in Zhou Duan's hand contained a third of the red mixture.

This is Xavier's blood, and after Zhou Duan returned, the brothers were waiting in front of the door.

Zhou Duan was not too surprised, seeing that the individuals around him had greater power, and as vampires, they were naturally also longing.

Zhou Duan drew some of their blood, and at this moment the two brothers were standing on the balcony waiting for Zhou Duan's test results.

Zhou Duan used a photonic microscope to look at blood samples and skin samples, which were very interesting for the brothers' cells.

Generally, human cells have a double cell membrane, and the hydrophilic ends are opposite each other and become the medium of material exchange.

However, there is only one cell membrane in their cells, and they are not divided into hydrophilic and hydrophobic, phospholipids and proteins are hugged.

This expands the concept of "resemblance dissolves," which is maximized in their digestive system.

The blood they suck carries with them a large amount of substances, and these substances and mitochondria in human cells are completely stored by the specialized structural cells within the vampire's digestive system to become "hemochondria".

The energy of this hemochondria is very high, emitting more than ten times more energy than mitochondria when broken down into other substances.

Coupled with the toughness of the cell membrane of the special structure, the vampire's body is easier to repair and carry more power than ordinary humans.

However, this "hemosome" is not stable, it will automatically decompose when exposed to light, and their cell membranes will show a "photoinert" phenomenon under light conditions.

So it's hard to survive in the sun.

What's interesting about the brothers' cells is that there are more microscopic "forces" in their cells that support the chemical bonds in the "hemochondria".

So that it remains stable even in sunlight.

The next discovery made Zhou Duan a little uncomfortable.

Vampires do not have "enzymes" in their bodies, they suck blood by the instinct and concentration difference of the cells, and as for other things, they rely on many strange "parasites".

There must be different antibodies in different bloods, and these antibodies have long since destroyed the vampire's human defenses.

But these parasites are the "new line of defense" that has been re-established in the vampire's body. ”

Zhou Duan called them blood nematodes.

They devour everything except blood, and then break it down into the necessary components of the "hemosomes", which are completely occupied by the majority of each vampire's body.

Regarding the nucleus, Zhou Duan didn't find much, would he care about the boring question of whether vampires and humans have reproductive isolation?

It's just that Zhou Duan is more puzzled by the fact that the cell activity of vampires is so poor, how can they differentiate into various life tissues similar to people?

Their cell activity decays periodically, and the preliminary estimate at the end of the week is that they will enter irreversible cell necrosis if they do not drink fresh blood for a week.

However, there is a high-energy substance called hemochondria......

Unfortunately, the brothers were frightened by their previous appearance and did not allow themselves to study it.

Zhou Duan smacked his lips with some regret.

"Can you find a way?" Xavier looked at Zhou Duan defensively.

I thought the other party was a warrior or something, but I didn't expect there to be such a perverted side.

You'll have to stay away from him in the future.

"Did you stop sucking human blood when the concentration of blood in someone else's body was the same as the concentration of blood in yours?" Zhou Duan suddenly asked the two.

"Almost."

Zhou Duan nodded, this is more reasonable, that is to say, the more "hungry" the vampire, the greater the danger.

"What the hell have you researched?"

"Yes." Zhou Duan shook the blood in his hand, "Theoretically speaking, your cell membrane is where you have the most proteins, and you have to start from this in terms of invertase and expression enzymes."

Can you let go of certain restrictions in the sun, I mean inactivate the nematodes in the injection area or drive them away or something. ”

"You want us to think of anything else...... Exposing the essence of vampires to the sun? Isn't that murder? Rice looked at Zhou Duan angrily.

"I'm interested, can I tell us?" Xavier understood that Zhou Duan would not lie about such a thing.

After all, he didn't need any reason to kill the two of them.

"There are limitations to this method, but you don't need to suck human blood to stay alive, and accordingly, your lifespan will decay with the cell cycle."

Les hesitated.

Xavier fell silent.

"I agreed." Xavier who spoke.

"Xavier!" Les looked at Xavier, a complicated look on his face.

"Les, the role of that thing is almost over, if we don't gamble, we will be killed sooner or later, just like Elena's strange power, we can't stop it at all."

Zhou Duan nodded, the vampire's resistance to things like the ability flame was too fragile.

"What am I going to do?" Xavier looked at Zhou Duan again.

"......" Zhou Duan didn't know how to speak.

"You don't think I know what the problem is and I'm going to solve it right away, do you?"

Xavier looked at Zhou Duan blankly, then what are you talking about?

"Not to mention how to protect the material exchange between your cells in the sun, the amount and timing of the enzyme alone have to be simulated countless times, and I still have some ...... Anyway, I can't do it now, I have to prepare for a few months, during which you brothers will suck whoever you like. ”

The two brothers who were kicked out by Zhou Duan stood on the steps a little cutely.

After Zhou Duan saw Xavier and them away in the room, his face also changed slightly.

The problem is much more than what he says.

This enzyme scheme does not work, because the brothers have absolutely no basic microscopic conditions for human beings.

But in addition to reassuring them, he also thought of another feasible solution, not because of Zhou Duan's kindness, but because he was also interested in solving the problem of how vampires evolve.

This plan also starts with the blood of those monsters.

A few wooden planks were used to isolate the laboratory, and Zhou Duan found a 2x2 space.

Field exploration, miniature detection instruments, drones, etc. are still very useful.

This requires the drone to perform like a satellite, otherwise there will be many cumbersome people in the team who can only operate the drone.

Zhou Duan's initial idea for his team was four people.

One stayed in the safe zone to operate the drone and guide the way, one was a doctor, and two were in charge of hunting.

But now the doctor may not know anything, or three people are enough.

I just don't know how many of them will join him.

And his next task, the historical text, what is this, is this a faulty civilization in this world?

The reason why some faulty civilizations are faulty is that most of them have appeared "things" that the world does not allow.

Just as he was thinking about it, there was a sudden knock at the door.

Zhou Duan opened the door, and it was Elena.

Walking into the room, Elena sat on the seat where Zhou Duan was tinkering with the drone, looking at Zhou Duan seriously.

"If you open the door to someone casually like you just did, I guess I'll only be able to collect your body next time."

Zhou Duan's hand closed the door and paused.

He looked at Elena: "I opened the door to rob. ”

Elena thought of Zhou Duan's skills and choked a little.

"Well, why are you here?" Zhou Duan himself also thinks that he and Elena are currently in an ambiguous period, but the external environment makes it difficult for Elena to focus on this aspect.

Zhou Duan focused on the task.

"I'm going to join your team, I've already got my mercenary card." Elena pulled out a green certificate.

"Welcome!"

Zhou Duan looked at the necklace around Elena's neck and said with a smile.

"But Aunt Monica, they ......"

"It's fine." Zhou Duan understood everyone's thoughts.

After Elena left, Zhou Duan had a new idea, and he called up the ground tune.

"You can be an intelligent ......"

"The host should understand that intelligence is impossible to be intelligent, and my existence cannot be recognized by a second person, but there is intelligence for sale, as long as three thousand points."

"I don't have points."

"Conservation Platform Launches Latest Installment ......"

"Impossible, unacceptable, non-existent."

"The rights of the Tinder do not calculate interest, and the current overdraft limit of the host is 10,000 points, as long as it is paid off within three worlds."

"Bought it."
