After traveling through time, I became friends with Tsunade

"Teacher, I choose the Multiplication Detonation Talisman!"

Yusuke stared fixedly at Sarutobi Hiruzen.

"Ok!"

Sarutobi Hiruzen looked at Yusuke with great satisfaction. This disciple was walking on a down-to-earth path and did not blindly pursue difficult ninjutsu. This was very different from other people.

"I will teach you this ninjutsu now. However, don't think that you can use it casually just because it is an A-rank ninjutsu."

Then, Sarutobi Hiruzen said to Yusuke with a serious face. Yusuke nodded to show that he understood, and then respectfully took the training method given to him by Sarutobi Hiruzen.

"I will grant you a piece of vacant land for you to practice. In addition, I have prepared a plan for your physical training. Although I don't know where you learned a ninjutsu that can enhance your strength and speed.

But you have to know that if you lose your ability to move before you defeat your opponent, you won’t even have a chance to escape. Therefore, it is very important to strengthen your foundation.”

"I understand, teacher!"

Yusuke knew that even though the ability of the String-String Fruit was very buggy, it was just a decoration if it couldn't hit the enemy. He was firm in his belief and prepared to start this special training that would last for an unknown period of time.

"A little later. I will check your strength recovery first, and then decide when to let you start special training!"

"Ok."

As soon as Yusuke finished speaking, Sarutobi Hiruzen left him and returned to his desk, picking up the document and reading it carefully. Seeing this, Yusuke did not leave, but stayed in the office to study the multiplication detonation talisman.

The multiplying detonating talisman is to stick a single detonating talisman to the enemy's vital points at an extremely fast speed. A single detonating talisman can continuously summon detonating talismans and trigger continuous targeted concentrated explosions.

However, these were all the first ninjutsu he learned. He still had the wind-style ninjutsu that Tsunade had given him in his room without touching it.

Perhaps, it can be combined with the String-String Fruit. But after learning it, you need to carry some detonating talismans with you.

Hey! Yusuke patted his wallet, which was not rich to begin with. Now, his wallet would become even emptier, and he estimated that he would not be able to carry out missions for a long time.

By the way, speaking of missions, his eyes lit up, as if he hadn't received the reward for this mission yet! Moreover, he was the hero who ended the battle in the Kingdom of Wind, so his teacher should at least give him tens of millions of yen.

But these are not important for the time being, Yusuke put aside those complicated thoughts. He tried to make a seal for the first time, and originally thought that his movements would be clumsy, but surprisingly, his technique was extremely fast and he did not encounter any difficulties. It must be because of muscle memory.

Not long after, Sarutobi Hiruzen finished his business and took Yusuke to the Death Forest. There were many animals living in the wild here, which were usually blocked, so there was almost no one else here except Yusuke and his group.

"Summoning technique!" As soon as he arrived in the forest, Sarutobi Hiruzen summoned the monkey demon.

"Sarutobi, Yusuke." After the Sarutobi appeared, he did not feel any danger. He looked at the battlefield and found that there were only the master and apprentice, so he greeted them unhappily.

"Enma, please check whether Yuyoujie's strength has recovered!" Sarutobi Hiruzen winked at Enma and said.

"Okay!" Yuan Mo immediately took an attacking stance towards Yusuke.

"Monkey head, get ready, five-colored thread!"

Yusuke's figure flashed, and he moved at high speed, rushing towards the ape demon like lightning, while swinging out dozens of thin threads. Seeing this, the ape demon did not dare to neglect it, and quickly dodged to the side, and then launched a counterattack.

Yusuke swiftly shuttled through the forest, skillfully avoiding the attacks of the monkey demon. The silk thread in his hand was like a nimble snake, sometimes winding and sometimes piercing, making the monkey demon defenseless.

The monkey demon was not to be outdone, and with its powerful strength and agility, it launched a fierce contest with Yusuke. Each of its attacks was so powerful that the air around it trembled.

The battle became more and more intense, with both sides fighting back and forth and neither side giving in.

After a fierce battle, Yusuke finally collapsed to the ground, breathing greedily at the air.

The ape demon was not in a much better condition. His clothes had become tattered and his hair was missing some sections.

Sarutobi Hiruzen looked at the scene in front of him with a look of joy on his face. He clapped his hands happily for Yusuke and said, "Yusuke, you did a great job. Your strength has not declined, but your speed has improved."

Seeing that Sarutobi Hiruzen didn't care, the Sarutobi demon on the side snorted at him: "Sarutobi, you have to prepare a few more sets of clothes for me!"

"Okay, okay!" Sarutobi Hiruzen looked at Enma helplessly and agreed. It was just a few sets of clothes, not worth much money.

After dealing with the Monkey King, Sarutobi Hiruzen turned around and taught Yusuke: "Yusuke, your bloodline limit is amazing no matter how many times I see it. However, your weaknesses are also very obvious, so physical training must be put on the agenda, and you must be mentally prepared."

After a short rest, Yusuke stood up and answered seriously, "I understand, teacher."

Sarutobi Hiruzen then turned around and looked at Enma, who nodded slightly at him, then bit his finger and performed the summoning technique.

After a puff of smoke gradually dissipated, a white-haired monkey with a bundle of scrolls tied to its back appeared in front of Yusuke.

"Sarutobi." The white-haired monkey nodded to Sarutobi Hiruzen first, then turned to Yusuke and said, "This is your disciple Yusuke, right?"

"That's right." Then, Sarutobi Hiruzen walked to Yusuke and began to introduce him to him.

"Yusuke, this is the elder of the Ape Clan, Ape Heart."

"Hello, Elder Yuanxin." Yujie greeted Yuanxin politely, but he was confused at the moment and really didn't understand what his teacher's intention was in making such an arrangement.

"Yusuke, although you are my disciple, there is not much I can teach you. Letting you learn other ninjutsu may be a waste of your time.

So, during this period of time, I have repeatedly thought that instead of letting you learn ninjutsu that may not be necessary, it is better to find you a strong partner to fight with you. So I decided to teach you the art of summoning spirits and let you sign a contract with the monkey clan! "

Sarutobi Hiruzen stared at Yusuke with a serious face, but Sarutobi said nothing, took out the scroll and spread it out in front of Yusuke, while Sarutobi took out a pen from somewhere and handed it to Yusuke.

Yusuke looked at the man and two monkeys in disbelief, muttering softly.

"Psychic art?"
