Kuro's complaints.
Rokuro didn't care much.
In his heart, he was currently overjoyed.
Just now, when he used Monstrous Strength, the system sent a notification:
[Monstrous Strength Level 2: Experience Points 0/20,000]
Seeing this message, how could Rokuro not be happy?
Just having learned it, it was already Level 2, saving 10,000 Experience Points.
This was still the first time—learning a ninjutsu and having it immediately be Level 2.
By the looks of it, learning those Medical Ninjutsu had made his Chakra control even more precise. This had an extremely good boosting effect on his training of Monstrous Strength!
Truly not bad!
In the future, he figured that when learning these kinds of ninjutsu that were easy for him, they might also go straight to Level 2. Who knows how many Experience Points that could save him? Just thinking about it was beautiful.
Kuro returned to Rokuro's side, looked at the table Rokuro had blasted into pieces, then looked at the scroll by Rokuro's hand. After thinking for a moment, he said in astonishment:
"Smelly brat, don't tell me you've already learned Princess Tsunade's Monstrous Strength!"
Rokuro snapped back to reality and smiled proudly.
"That's only natural. For a genius like me to learn this kind of ninjutsu, isn't that just a normal occurrence? What's so strange about it?!"
Kuro's expression twitched.
He said it so simply!
If it were really that easy, why would Tsunade be the only one in Konoha Village who knew it?
Kuro complained secretly for a while, gently patted Rokuro's head, shook his head, and sighed.
"If you learned it, then you learned it. But can you not show off in a place like this? If you really want to show off, then find a safe place to do it, alright?!"
Rokuro cast a glance at Kuro and stood up.
"Master, right now I really want to find a place to test it out. I'll leave this place for you to handle. I'm going out to find a small place to train first. Pack a portion of delicious food and take it back to the inn for me. I'll head back once I'm done training!"
Finished speaking, Rokuro hurriedly ran out of the restaurant.
Then he ran wildly all the way, out of Chang'an Town, and found a place with no one around.
Having just learned Monstrous Strength—and having it directly level up to Level 2—made a special idea pop into his mind.
That was: if he trained those low-level ninjutsu right now, would the speed at which their Experience Points increased also rise rapidly?
If that was truly the case, then he could spend a lot less Experience in the future—and save all that Experience to upgrade high-level ninjutsu.
Arriving at a deserted area, he impatiently split off five Shadow Clones and instructed them:
"Right now, all of you train the Earth Wall Jutsu for me, until your Chakra is completely used up. Do you understand?!"
The five Shadow Clones scattered, each finding a spot and starting to train the Earth Wall Jutsu.
As for his main body, he stayed in place, staring at the Earth Wall Jutsu's Experience Points in his attributes.
Ten minutes later, his heart was filled with wild joy.
It was exactly as he thought.
The stronger his strength became, the higher the Experience Points gained from training low-level ninjutsu.
Originally, when he trained Earth Release ninjutsu before, a single success would only increase it by one or two points of Experience.
But now—training the Earth Wall Jutsu, which was also a C-Rank ninjutsu, increased the Experience Points by 10 to 15 points at a time.
That is to say, for him to upgrade the Earth Wall Jutsu to Level 2, he would need to train it 100 times at most.
If he used five Shadow Clones to train 100 times, he would spend at most 300 Experience Points to recover his Chakra.
In other words, he only used 300 Experience to exchange for the effect of 1,000 Experience Points—and all he paid was just a bit of time.
And right now, the thing he lacked the least was time.
Getting this result, Rokuro's mood instantly improved.
In the past, he didn't use Experience Points to upgrade those low-level ninjutsu because he despised wasting them. But now that he could upgrade them through his own training, it became necessary.
Anyway, his time wasn't worth money—exchanging it for some ninjutsu was worth it.
Forty minutes later, his Earth Wall Jutsu upgraded to Level 2.
And he had only spent 200 Experience Points to recover his Chakra.
Under such circumstances, Rokuro was extremely satisfied.
He had originally felt hungry, but now he wasn't hungry anymore.
He continued to split off Shadow Clones to train the Earth Wall Jutsu.
He wanted to see just how long it would take to upgrade it to max level.
Training.
He lost track of time.
Training from daylight until it was dark.
It was only when he heard the system notification—that the Earth Wall Jutsu was already Level 5—that he finally snapped back to his senses.
Looking at the time, there was still about forty minutes until dawn.
Looking again at the day's consumption—3,200 Experience Points were gone.
Spending 3,200 Experience Points to upgrade a C-Rank ninjutsu to max level, allowing its power to reach that of a B-Rank ninjutsu—this result could still be considered worth it.
By the looks of it, in the future, when he had free time and Experience Points, he would spend some time upgrading all the low-level ninjutsu to max level.
