Naruto: The God of Bloodlines

The next day, Yasu went to the Forest of Death to continue his chakra control training. He attempted to climb a tree but quickly fell to the ground.

Yasu was surprised and quickly realized that the weights he was wearing required him to use more chakra to climb the tree as he had done before. This was a good thing since the weights enhanced his chakra control training.

After two attempts, Yasu figured out how much chakra he needed to climb the tree as he did previously. Fortunately, with the experience gained the day before, Yasu soon managed to climb high into the tree, only to fall again.

Yasu resumed his intense training, and within a few hours, he successfully reached the top of the tree. Still, he didn't stop there—he continued climbing different trees, using faster steps to further hone his chakra control.

Yasu noticed his rapid improvement and no longer fell from the trees, even as he changed his climbing methods multiple times. He trained until his chakra was nearly depleted, then moved on to taijutsu training.

This time, Yasu found it difficult to perform more than 100 push-ups without resting. He quickly switched to doing squats until he was fatigued again. While resting his arms, he decided to sprint through the Forest of Death as much as he could until his legs gave out.

Once his legs were exhausted from running, Yasu returned to doing push-ups. This time, he couldn't complete even 100 and moved on to other exercises until he was completely drained.

After exhausting himself with all this training, Yasu was pleased to see that his body had become slightly stronger and his chakra had increased a bit. This training not only provided him with benefits from the system but would also reward him again as his bloodline purity improved.

In the following days, Yasu continued the same training routine. He noticed steady improvements in his chakra control as he practiced walking on trees. When his chakra ran out, it was time for taijutsu training.

Yasu was excited about his training, seeing the results materialize. Being intelligent and realizing how much stronger he had become, he started taking on far fewer village jobs that required him to carry heavy loads.

These tasks were underestimated by shinobi because the pay was much lower than that of a genin mission, but for ordinary people, several workers were needed to complete them. 

However, since Yasu couldn't work as a shinobi, he accepted these jobs and completed them quickly, earning more money than before while working much less. This gave him more time to train.

Yasu wasn't afraid to show his strength to the shinobi in the village because everyone knew he had always trained with Guy. Even though they believed Yasu lacked talent for taijutsu, they expected him to be strong after years of training.

Only Guy knew that Yasu's previous training had been ineffective, but after awakening the system, Yasu received all the rewards for the hard work he had done over the past years.

After so much training in the Forest of Death, Yasu realized he no longer needed to practice chakra control by walking on trees. It was time for the next step in his training: mastering chakra control by walking on water.

Yasu knew this training would be much harder and take longer for him. After all, he didn't have Naruto's absurdly large chakra reserves and understood it would take him much longer because his chakra would deplete faster.

Even so, this training was essential if Yasu wanted to use jutsu effectively in the future. Although there were other methods to train chakra control, water-walking was what Yasu decided to focus on for now.

Yasu went to a river in the Forest of Death and decided to use it for his training. He stepped onto the water and used a significant amount of chakra to keep his foot steady. Then, he did the same with the other foot and began walking on the water.

At first, Yasu's feet sank into the water, but he didn't fall and managed to walk while partially submerged. With the weights he wore for training, Yasu needed much more chakra just to stay on the water without falling.

Yasu finally understood how difficult this training was. His chakra control had improved significantly after practicing on trees, but trees were stable surfaces. Walking on water required him to constantly adjust the chakra output needed to stay balanced.

After a few hours, he managed to walk on the water with difficulty, finally staying above the surface instead of having his feet partially submerged. However, by the time he achieved this, his chakra was almost completely depleted.

Yasu felt frustrated because he could train his chakra control for far less time compared to his tree-climbing practice. Still, he knew this was because he was using much more chakra than necessary to stay on the water while learning.

Even so, Yasu realized that this training was far more beneficial to him than tree climbing. If he could master running on water, his chakra control would reach the level needed to perform jutsu without worrying about excessive chakra wastage.

Moreover, this was the best method available to Yasu to deplete his chakra reserves, which in turn would help increase them. It also made his taijutsu training more effective, making this an ideal training regimen for him.

After all this time, Yasu's taijutsu training had also improved. He could now do 300 push-ups in one go before starting to feel tired. Afterward, he would do 300 squats and could run for much longer through the Forest of Death.

It didn't seem like a significant improvement, but when he finished running exhausted, Yasu had already recovered enough to do another set of 300 push-ups. This made his training far more efficient than before.
