The next day, Mo Yu arrived at the ninja school, where he was handed a brand-new ninja headband and a ninja identification card.
"ID number: 002233."
This item was essentially like an ID card, recording all of your information, including your strength, mission completion, and more.
From today on, Mo Yu would officially be a lower-ranked ninja of Konohagakure.
After completing the necessary procedures, Mo Yu initially thought he would be assigned to a team.
However, that did not happen.
After inquiring, Mo Yu learned that Konohagakure had not yet implemented the system of assigning lower-ranked ninjas to be led by higher-ranked ninjas.
For example, teams of one jonin or chunin leading three genin—a system that would not appear until after the Second Shinobi World War.
Currently, unless it was a master-apprentice relationship, like the Sannin with their teacher Hiruzen Sarutobi, there were no powerful ninjas willing to specifically lead inexperienced rookies.
Of course, ninja families had their own internal systems. For example, those born into prominent ninja families naturally had their own organizational structure.
For Mo Yu, a civilian-born ninja, it meant he would have to rely entirely on himself.
And this, in fact, was a good thing for him.
His secrets were numerous, and if he had teammates for every mission, he would be restricted by the need to hide his abilities.
With the system in place, Mo Yu didn't lack experience and didn't need anyone guiding him.
Being a lone wolf suited him perfectly—free and unrestrained.
Two days later, at night.
Mo Yu set up a bathtub and filled it with hot water.
It had been three days since he last used the Zhilong Strong Body Ointment, so today he could apply it again.
This time, he planned to try using both the Zhilong Strong Body Ointment and the Water-Thunder Body Forging Technique together, to see what kind of effect they would have.
He sprinkled the powder into the water, and it quickly turned into a dark green color.
Then Mo Yu exchanged a Thunderstone from the system.
This time, the Thunderstone was about the size of an egg, costing 2 gold coins, and it contained much more stored lightning.
He threw the Thunderstone into the tub.
The dark green liquid now had a layer of purple hue on top, bubbling and making an eerie sound.
Everything was ready, all that was left was to dive in.
He took a solid pill, placed it in his mouth, and stepped into the tub.
"Ah!"
Mo Yu's face instantly turned red, his features contorting in pain. It was excruciating.
The Zhilong Strong Body Ointment and the Thunderstone seemed to have triggered some kind of chemical reaction, and the pain was more intense than when either was used alone, at least ten times worse.
It felt like he had fallen into a "mountain of needles," with sharp pain shooting all over his body.
But in order to test the effects, Mo Yu gritted his teeth and endured it, starting to operate the Water-Thunder Body Forging Technique.
His pores opened, and the water, lightning, and medicinal liquid combined together and were absorbed into his body.
Normally, when Mo Yu wanted to absorb a full tub of Zhilong Strong Body Ointment, it would take at least half an hour.
And the slower the absorption, the more medicinal effect would be lost. In the end, he would usually only absorb about 50-60% of the total medicinal effect.
Now, his absorption speed had been increased several times. Every drop of the medicinal liquid was sucked into his pores without any waste.
Moreover, the medicinal effects of Zhilong Strong Body Ointment seemed to be boosting Mo Yu's body's ability to absorb lightning, creating a beneficial feedback loop.
In just about ten minutes, the entire tub of liquid had been absorbed, leaving behind only an exhausted Thunderstone.
This time, Mo Yu's body showed obvious changes.
His muscles swelled, the lines were more defined, and a "田" shape could vaguely be seen on his lower abdomen.
Mo Yu, excited, only wore a pair of shorts and couldn't wait to test his newfound strength.
After a simple test, Mo Yu estimated that compared to before he soaked in the medicinal bath, his body had been enhanced at least five times.
Strength, speed, stamina, reflexes, and recovery—all had drastically improved.
He had gone from a sickly, weak person to someone stronger than an adult who exercises regularly.
The most exciting part was that Mo Yu measured his height and found he had grown three centimeters taller.
The once skinny Mo Yu now appeared taller and stronger than his peers.
"Next, I can use both the medicinal bath and the Water-Thunder Body Forging Technique together, and also do high-intensity training at the same time. This double approach will yield the best results," Mo Yu decided in his mind.
From that day on, Mo Yu threw himself into intense training.
He spent one gold coin to exchange for a large quantity of training equipment from the system. Starting with basic leg weights, he had everything from 10 kilograms to 50 kilograms, and even 100 kilograms.
These common items were inexpensive, and one gold coin was more than enough.
Previously, due to his poor physical condition and lack of money, he couldn't train effectively.
Now that his body had improved, he was no longer lacking in money, and with both the medicinal baths and Water-Thunder Body Forging Technique, Mo Yu could push his body to the limit without worry.
No matter how exhausted his body became or how badly injured he was, as long as he soaked in the Zhilong Strong Body Ointment bath and took two solid pills a day, all injuries would be healed, leaving no lasting effects.
So, from that day on, a young man could be seen running around the village every morning before dawn.
This boy would sometimes drag a large stone behind him, leaving a deep track on the ground; at other times, he would run on his hands, using only two fingers instead of his feet—an unusual sight.
Of course, while training his body, Mo Yu did not forget one other thing.
That was to familiarize himself with his Sharingan.
In his battle with Arima Kouichi, he had been able to defeat the enemy with a higher rank due in large part to his Sharingan. Therefore, Mo Yu placed great importance on this trump card.
The primary ability of his single-tomoe Sharingan was "insight." So, Mo Yu focused on enhancing his visual acuity.
For example, he would stand under a tree and use a wooden sword to chop falling leaves.
At first, he could only hit one leaf out of seven or eight attempts.
But as he trained and balanced his vision and the speed of his strikes, Mo Yu could eventually strike three times in a second, and each strike would hit a leaf.
Later, to increase the difficulty, he added ten kilograms of weight to each of his arms to improve his arm strength and the speed of his strikes.
Through this training, Mo Yu unknowingly made some progress in his swordsmanship. He began to understand the "speed" and "precision" principles of swordplay, something that he stumbled upon without realizing it.
