Upper Capital, deep underground research facility, main conference room.
The giant circular screen still displayed a summary of the key points from last night's contact with Hyuga Tianyi.
Especially the description of his requirements for "Water Release: Water Severing Wave."
The long conference table was full. Aside from Commander Tian and several core leaders, the rest were all senior engineers.
Commander Tian tapped the tabletop, drawing everyone's attention away from their terminal screens.
"Everyone has seen Comrade Tianyi's latest requirements.
In the short term, he needs to develop effective combat capability.
Water Severing Wave has been listed as one of the priority targets.
What ideas does everyone have regarding this ninjutsu? How can we provide him with the most efficient support?"
After a brief silence, a middle-aged man wearing thick glasses and plain work clothes raised his hand.
He was Engineer Chen, an expert in materials and high-pressure fluid mechanics.
He brought up a 3D model on his terminal and projected it onto the auxiliary screen.
"Commander Tian, everyone," Engineer Chen said steadily, with an engineer's characteristic practicality.
"I have carefully analyzed the description of Water Release: Water Severing Wave.
Setting aside chakra, the energy medium we have yet to fully understand.
If we consider only the high-pressure water jet cutting effect it aims to achieve.
It overlaps heavily with, or could even be said to be identical to, the highly mature waterjet technology already used in our industrial sector."
An animation explaining how an industrial waterjet worked appeared on the screen.
Engineer Chen continued, explaining as he pointed at the animation:
"An ultra-high-pressure pump drives water to an extremely high pressure.
Then it sprays it through an exceptionally fine gem nozzle, forming a high-speed jet.
"The principle is simple: create high pressure, then release it under constraint.
And Comrade Fang Tianyi only needs to use chakra.
To serve here as both the ultra-high-pressure pump and the precision nozzle controller.
Then he can achieve the power of Water Release: Water Severing Wave."
The display changed, showing real footage and data of waterjets cutting through metal and composite materials.
"Moreover, the current optimization directions for industrial waterjets are very clear:
Pressure, flow rate, spray distance, nozzle wear, and the addition of abrasives."
"Abrasives?" A female bioenergetics expert looked up.
"Yes, things such as fine garnet sand and aluminum oxide grit," Engineer Chen confirmed.
"Pure water jets have no problem cutting soft materials, but they are not enough against hard materials.
After hard granular abrasives are added, their cutting ability increases exponentially.
We can offer Comrade Tianyi this line of thinking.
His world may not have standardized industrial abrasives.
But fine sand and hard mineral fragments should always be available.
If, while using the waterjet.
He can use chakra to mix and accelerate such tiny hard particles into the water flow..."
He paused and looked at Commander Tian. "Then the power of this waterjet.
May greatly exceed the original power recorded for Water Release: Water Severing Wave."
A quiet murmur of discussion arose in the conference room.
This idea broke beyond the framework of merely analyzing ninjutsu.
It directly entered the realm of applied-science optimization. It was ingenious and highly feasible.
Commander Tian lightly tapped the table with his fingers, his gaze sharp.
He did not state his opinion immediately, instead looking toward another person in charge.
"Little Liu, from the perspective of energy-matter coupling.
What is the estimated technical difficulty of implementing Engineer Chen's abrasive-mixing concept on Tianyi's side?"
Dr. Little Liu rapidly ran calculations and simulations on her tablet. After a moment, she looked up.
"If the essence of Water Severing Wave is chakra being highly condensed and pressurized.
Driving water molecules into a directional jet.
Then mixing solid particles into it should theoretically only require more precise chakra control.
Simultaneously enveloping, accelerating, and directing two substances in different states of matter.
There is difficulty involved, but it is not insurmountable."
After hearing this, a barely perceptible hint of approval appeared on Commander Tian's face.
With a sweep of his hand, he gave his orders decisively.
"The idea is clear, the logic is complete—excellent! Engineer Chen, your group will act immediately!"
"First, compile the core principles and key technical parameters of industrial waterjets, including but not limited to:
Pressure, flow velocity, the effects of nozzle design on jet shape, and so on.
Pay particular attention to the detailed operating principles of abrasive waterjets, as well as empirical data on abrasive selection and mixing ratios.
Produce the clearest and most concise guidance document possible."
"Second, do not provide nothing but dry data. Add diagrams and dynamic simulations of the principles.
List multiple alternative abrasives and provide comparisons of the changes in power under different mixing ratios."
"Third, consider simultaneously whether, if the Water Severing Wave ninjutsu can be stably achieved and optimized.
There will be a possibility in the future of combining it with his lightning affinity.
To develop an electrolysis-enhanced waterjet or an electromagnetically accelerated waterjet.
Treat it as a long-term related project and include it among the Thunder Division's preliminary research options."
"Finally, place these materials near the top of the priority list for the next batch of material and information support sent to Comrade Tianyi.
Tell him to first understand the principles and establish a solid foundation of control before attempting to incorporate the concept of 'abrasives.'
Proceed steadily. Use scientific methods to turn this Water Release: Water Severing Wave.
Into his first reliable scientific ninjutsu weapon."
"Yes!" Engineer Chen, Little Liu, and the others answered in unison.
When Tianyi received the news that night, he was overjoyed.
After studying the materials, he immediately began trying it out.
Extreme compression, a tiny outlet, instantaneous release.
He raised his right hand, palm facing upward, and focused intensely.
Pale blue chakra began to emerge. Soon, a transparent water sphere the size of a watermelon condensed into shape.
This was only the beginning. Tianyi took a deep breath and began the most crucial, and most dangerous, step: compression.
As more chakra was injected, following the instructions in the materials for increasing pressure.
He used chakra to evenly and firmly "squeeze" the water sphere from every direction.
Under the pressure of the chakra, the water sphere visibly shrank.
It went from the size of a watermelon to a soccer ball, then to a baseball.
The water sphere's color also became deeper as its density increased.
"This is the limit..." Fine beads of sweat formed on Tianyi's forehead.
He could clearly feel that within the baseball-sized water sphere in his palm.
There was an extremely unstable high pressure.
The chakra coating was like a membrane stretched to its absolute limit.
If he injected more chakra or applied greater pressure.
The water sphere would likely lose control and explode immediately.
This was far more dangerous than the mechanical pumping described in the materials.
Everything depended on his own chakra control to maintain the balance.
"Then I'll first try opening a hole at this level of pressure."
He cast aside every distracting thought, even slowing his breathing.
All his focus sank into his palm, locking onto that high-pressure water sphere.
At a selected point on the water sphere's surface, he began shaping an outlet.
Now!
"Whoosh—!"
A faint sound of something cutting through the air rang out.
A stream of water as thick as a pen shaft shot forth at incredible speed.
Pfft!
