"What do you want me to do?" Amado did not shake hands immediately, but asked calmly.
"It's very simple." Senju Chen smiled, "Continue your research. Human body modification, Scientific Ninja Tool, biological weapons... you can do whatever you want. I will not interfere with your research direction, nor will I restrict your freedom."
"Then what do you want?"
"I want results." Senju Chen's eyes became sharp, "A result that can change the pattern of war, a result that allows ordinary people to have the power to match the power of ninjas, a result that allows me to stand firm in this chaotic world."
He paused and added, "Of course, if you need any special 'materials' for your research, I can also help you get them. For example... some rare Kekkei Genkai owners, or some special experimental subjects."
Amado's eyes flashed with a strange light.
This young man... he not only understands science, he also knows how to navigate the gray areas of the world.
Such a partner is rare.
"I have a question." Amado suddenly said, "You said you can provide experimental subjects. Then... are you willing to be the experimental subject?"
Senju Chen was stunned for a moment, then smiled.
"You want to experiment on me?"
"It's not an experiment." Amado shook his head, "It's a verification. If you really believe in the power of science, you should be willing to use your own body to verify this power. Otherwise, what's the difference between you and those investors who only talk?"
This is a temptation.
Amado wants to see if this young man really agrees with his ideas, or if he is just trying to spread the pie.
Senju Chen was silent for a moment, and then he rolled up his sleeves without hesitation.
"Yes." His voice was calm, "But I have one condition - it cannot affect my combat effectiveness, and it cannot leave any obvious sequelae."
Amado stared at him, and the scrutiny in his eyes gradually turned into appreciation.
"Deal."
He finally reached out and took Senju Chen's hand.
The two hands held each other tightly, as if at this moment, they had reached some kind of tacit understanding that transcended words.
One is a mad scientist who is eager to use science to change the world, and the other is a time traveler who will do anything to become stronger.
Two equally dangerous people formed an alliance in this cold blacksmith shop.
In the next few days, Senju Chen was in no hurry to leave Land of Iron.
He stayed in this dilapidated blacksmith shop and had in-depth communication with Amado.
Amado showed his current research results - a potion that can temporarily increase the speed of nerve response, a wristband that can shoot high-heat metal needles, and an unfinished device that claims to be able to absorb and transform Chakra.
In Senju Chen's opinion, although these things are still very rough, they have already shown amazing potential.
Especially the device that absorbs Chakra.
If it can be perfected, it means that weapons can be made to restrain ninjas. Even... you can use it to collect Tailed Beast Chakra.
"What is the principle of this device?" Senju Chen picked up the semi-finished product and looked at it carefully.
"The essence of Chakra is a kind of energy fluctuation." Amado pushed his goggles and entered the explanation mode, "Any energy fluctuation can be absorbed and transformed by a specific medium. I use a special metal alloy, whose molecular structure can resonate with Chakra, thereby 'capturing' it."
"But the problem is that the carrying capacity of this metal is limited. Once the absorbed Chakra exceeds the threshold, it will collapse." Amado frowned, "I need to find a more stable material, or... find a way to convert the absorbed Chakra in time."
Countless thoughts flashed through Senju Chen's mind instantly.
If only this could be solved...
That means that a device that can absorb Chakra infinitely can be created.
This is simply a ninja's nightmare.
"I have an idea." Senju Chen said slowly, "Have you heard of 'Sealing Jutsu'?"
"Sealing Jutsu?" Amado was stunned for a moment, "Isn't that a ninja thing?"
"Yes. But the essence of Sealing Jutsu is actually a kind of restraint and transformation of energy." Senju Chen's eyes flashed with excitement, "If you can combine the principle of Sealing Jutsu with your device..."
Amado's eyes lit up instantly.
"You mean... use the runes of Sealing Jutsu to enhance the carrying capacity of metal?"
"Not only that." Senju Chen shook his head, "We can also use Sealing Jutsu to convert the absorbed Chakra into other forms of energy. For example... electric energy, or heat energy."
The two looked at each other and saw the same madness in each other's eyes.
This idea is simply crazy.
But... it's too tempting.
In the next few days, the two of them had almost no rest and were completely immersed in research.
Senju Chen shared his knowledge of Sealing Jutsu with Amado without reservation. And Amado used his scientific thinking that transcended the times to deconstruct this knowledge and integrate it into his device design.
Two completely different knowledge systems had a wonderful chemical reaction in this dilapidated blacksmith shop.
Finally, late at night on the fifth day, a brand new device was born.
It looks like a bracelet, completely black, with densely engraved runes on its surface.
"Try it." Amado handed the bracelet to Senju Chen with expectation in his eyes.
Senju Chen took a deep breath and put the bracelet on his wrist.
The next second, he mobilized the Chakra in his body and slowly injected it into the bracelet.
The runes on the bracelet instantly lit up with a faint blue light.
Senju Chen can clearly feel that his Chakra is being absorbed by the bracelet, and then... converted into a brand new energy, which is stored inside the bracelet.
"Successful..." Amado's voice was trembling.
Senju Chen said nothing, and he continued to increase the output of Chakra.
The light on the bracelet became brighter and brighter, but it did not collapse, but steadily carried this power.
It wasn't until Senju Chen stopped outputting that the light on the bracelet gradually dimmed.
"How's the storage capacity?" Amado asked eagerly.
Senju Chen Close your eyes and feel the energy inside the bracelet.
"About... equivalent to 30% of my Chakra energy." He opened his eyes, eyes flashing with excitement, "Moreover, this energy is very stable, with no signs of loss."
Amado finally showed a satisfied smile on his face.
"This is just the first step." He pushed up his goggles, "What we have to do next is to miniaturize this device and... weaponize it."
Senju Chen nodded.
He knew that this was just the beginning.
But this beginning was enough for him to see the infinite possibilities in the future.
