Successful Experiment

After dealing with the matters in the Land of Waves and the Land of Water, Cain hurried back and went straight to the underground laboratory of Tsunade and Orochimaru.

Upon seeing Cain, Orochimaru's eyes lit up, and he said, "Mr. Cain, the serum has run out. Although we have made some progress, we need to proceed with the next phase of the experiment."

After Orochimaru finished speaking, Tsunade saw Cain's gaze turn to her and continued, "Orochimaru is right. We have collected a lot of useful data. We can basically confirm that the Extremis Virus can suppress the erosion of my grandfather's cells. My grandfather's cells can also enhance the metabolic function of the test subjects, bringing the two into an equilibrium state."

Cain asked, "What's the catch?"

"The catch is that when we thought the experiment was successful, they exploded, which may be related to 'emotions.'"

Tsunade said helplessly. If the test subjects remained unconscious, they could declare the first experiment successful. No matter what kind of injury, it could be quickly recovered through the Extremis Virus, even if the test subject's palm was cut off.

However, when the test subject woke up, their emotions fluctuated until they reached a peak, and their body experienced a violent explosion.

But judging from the scale of the explosion, Tsunade and Orochimaru had indeed made significant progress. At least the last explosion left a few intact bones.

"The equipment for collecting data and medical examinations should have alternatives we can buy on this side of the world. Although they are a bit more expensive, use those for now. As for the serum, it will be sent to you in a few days. Let me take a closer look at the data first."

Cain rubbed his head and said. Orochimaru didn't care about the cost of human life in the experiments, and his methods were brutal and efficient, but they were too expensive. He brought three sets of equipment, and all the medical detection equipment was destroyed. Cain cared more about the money spent on these devices than the cheap cost of human life. He also didn't want to travel frequently between the two worlds just to deliver equipment to Orochimaru.

It's better to customize more devices in the ninja world. After all, detection equipment is not the core. If other equipment is destroyed, Cain would be truly heartbroken.

As Cain reviewed the experimental data from the past few days, Orochimaru said, "If possible, it would be best to send some different test subjects, such as teenagers, women, children, and ninjas."

Upon hearing this, Cain looked up and asked, "Can I call you Orochimaru-san?"

"Just call me Orochimaru."

"Alright, you can call me Cain too, Orochimaru. The first three are easy to find in the prisons of the Land of Fire, but the last one might be difficult for me. Do you have any connections?"

Orochimaru smiled and said, "There are quite a few imprisoned ninjas in the Konoha, but if we want people from there, they might have a legitimate reason to interfere with our affairs. I believe you wouldn't want to see that situation."

"In that case, let me figure it out."

Cain shook his head and said, deciding to spend more money to have Kakuzu capture some ninjas and, at the same time, clean up the rogue ninjas in the Land of Tea.

Tsunade didn't comment on this matter. Although she had accepted human experimentation, she didn't want to actively participate in such discussions. Perhaps she held the mentality of 'for my brother, there is no other way,' willing to be passive but not wanting to be active.

"You even have a way to get ninjas? Impressive, Cain."

Orochimaru praised with a smile. He was becoming more and more interested in the power behind Cain. Researching something like the Extremis Virus without a professional team was impossible.

"You can even activate the Wood Release bloodline?"

Cain saw that some of the test subjects showed abnormal performance and asked in surprise.

Tsunade replied, "Indeed, if the Extremis Virus doesn't go out of control, it can reproduce my grandfather's Wood Release ninjutsu."

If this experiment is successful, Tsunade would like to give herself a shot, but she knows that Cain is the kind of person who is dead set on money, and he won't give her an extra gram of serum unless she can come up with something that can move Cain's heart.

For a while, Cain traveled between the experimental base, Kawaki Town, and the capital of the Land of Fire. He was now basically the logistics manager of the experimental base, arranging equipment and test subjects and sometimes returning to the Marvel world to bring Maya and Killian's research results on the Extremis Virus to the world of ninjas.

The two of them had never seen Hashirama's cells, so Cain didn't plan to give them Orochimaru and Tsunade's research data. Otherwise, it wouldn't make sense.

In addition, Cain spent a lot of time practicing ninjutsu. He had become quite proficient in the Clone and Shadow Clone Technique, but his hand seals were a bit slow. He could make three seals at his fastest speed in a second, but that was when he was performing exceptionally well. Under normal circumstances, Cain could only make two seals per second.

However, Cain's chakra attributes were strange. His chakra attributes had become a complete set of five attributes.

Kakuzu was surprised when he learned this news and then shook his head with a sigh, thinking that Cain's talent was wasted on such good attributes. Regarding chakra volume and ninjutsu talent, Cain was unsuitable to be a ninja.

Cain guessed that the change in his chakra attributes might be related to Kakuzu's chakra. He was not originally from the world of ninjas and had never been exposed to chakra before. Strictly speaking, he was only weaker as the first group of people who received chakra from the Sage of Six Paths.

However, Cain didn't care about his own strength. He had a clear positioning: when faced with unavoidable danger, he would use the system to travel between the two worlds, equivalent to the invincible Flying Thunder God Technique. No barrier or sealing technique could restrict him.

Learning other ninjutsu was only for hiding his identity and whereabouts, and researching the Extremis Virus and Hashirama's cells was to enhance his physique.

Cain's position was that of a boss, not a front-line fighter. He spent 30 million taels to have Kakuzu teach him for a month just to learn the Earth Release: Hiding Like A Mole Technique, which would allow him to quickly dive underground and escape in the Marvel world when in danger.

"Calm down, Tsuchi-kun. If you can survive, we will let you go and give you some money, but you have to cooperate."

"Ah! Ah! Ah!"

Bang!

Before Orochimaru could finish speaking, the test subject in the isolation area exploded again, but this time only an arm exploded, and it was slowly recovering. The bones, blood vessels, and meridians were all visibly healing.

"Did we succeed?"

Seeing this, Tsunade quickly recorded all the test subject's physical reactions and pulled up the ratio of Hashirama's cells and Extremis Virus.

"Hehe, it seems my guess was correct, Tsunade."

Orochimaru laughed smugly. Although his experiments caused the death of many test subjects, they were not wasted. The person in front of him proved everything. He was only a few repeated experiments away from success.
