Climbing Tree Training

Although Ino never openly expressed her feelings for Chen, Yoshino, who also liked Chen, could see her thoughts. Then Yoshino would always pick on Ino, opposing her everywhere. After all, she wouldn't give Chen up to anyone. Anyone who dared to have ideas about Chen would be her enemy.

Later, Ino understood why Yoshino liked to trouble her so much. It was because Yoshino already knew she liked Chen, so she was afraid Ino would snatch Chen away.

This time, Ino couldn't stand it anymore. "He's not yours, is he? You like Chen-kun, and I like him too. If you're going to trouble me, then I'll trouble you back. Let's see who's afraid of whom."

In the end, the two, who had no intersection in the original work, became rivals. Every day they would mock and ridicule each other, and every day they would fight fiercely, neither willing to back down. Ino's originally introverted personality gradually changed because of this, becoming cheerful and bold like Yoshino. She no longer hid her feelings for Chen as before but expressed them boldly like Yoshino. The two thus became sworn enemies like Sakura and Yoshino in the original work, staging a "two women fighting for one man" drama in the classroom every day. It was common to see Ino and Yoshino each holding one of Chen's hands, pulling him like a tug-of-war, neither letting go. This made Chen, who was in the middle, very helpless. Although helpless, Chen did not feel annoyed; instead, he rather enjoyed it.

However, it was also more than a year ago that, due to the extermination of the Uchiha clan, Chen suffered a severe mental blow and became a mentally incapacitated idiot who couldn't take care of himself. So he dropped out of school and had been recuperating at home. At first, everyone would visit him, but upon finding no signs of improvement, they gradually forgot about Chen. However, Yoshino and Ino always believed Chen would get better and would visit him every few days. But Chen didn't remember them, so they returned disappointed every time.

Finally, because they often visited Chen together, the two of them could feel each other's feelings. They slowly went from competing with each other to understanding each other. Then they comforted each other, cheered each other on, and gradually became very good friends. They firmly believed that Chen would definitely get better, and both were praying for Chen, hoping he would recover his former self soon and silently waiting for him.

"Yoshino and I will always wait for Chen to get better!" Yoshino said to Sakura with a smile, her eyes firm.

"You and Yoshino? Could... could it be that you... you two?" Sakura looked at Yoshino, then at Ino, her eyes filled with disbelief.

"Yes! That's right, Yoshino and I will no longer argue over Chen. We both understand each other's feelings for Chen and won't give up easily. Moreover, the most important thing now is to wait for Chen to get better."

"Are you crazy? How can this be?" Sakura thought Yoshino must be crazy to say such a thing: "Besides, no one would agree to this kind of thing. Yoshino, wake up! Stop obsessing over Chen and forget him."

"I'm not crazy, I know very well what I'm thinking, so Sakura, you don't need to say anything more." Yoshino "You... you...!" Sakura was so shocked by Yoshino that she couldn't speak.

"Alright, let's go back to our seats. Teacher Iruka will be here to teach class soon," Yoshino said, walking towards her seat.

"Crazy, she's really crazy! No, I must persuade Yoshino to come back, this is too absurd!" Sakura couldn't accept such a thing. She thought Yoshino was just confused for a moment and would surely come to her senses if she persuaded her again.

At this moment, Iruka had already arrived in the classroom and was preparing to teach. Sakura had no choice but to return to her seat, but she couldn't listen to anything Iruka was saying now. She was only thinking that no matter what, she had to make Yoshino forget Uchiha Chen.

Meanwhile, Chen got up when Sasuke went out. After eating the breakfast Sasuke left for him, he planned to return to the laboratory to continue his training.

However, this time it wasn't as troublesome as yesterday. Because after obtaining the Flying Thunder God Technique yesterday, Chen had planted the Flying Thunder God's spatial coordinate formula in that laboratory. Not only in the laboratory, but Chen had also planted the coordinate formula in his own room, allowing him to move freely between the laboratory and his room.

"I need to make some preparations, in case Sasuke suddenly comes back and can't find me and gets anxious. I'll leave a clone in the room," Chen thought. "A Shadow Clone would be better. Shadow Clones are better than Clone Techniques, and their use is very important. They can be used for training and as a means of attack, which is very practical and must be exchanged."

"Clone Technique creates an illusion, not a physical body, which can only confuse ordinary ninjas' sight (Sharingan and Byakugan can see through it) and has no offensive capabilities."

"Shadow Clone creates a clone identical to oneself by dividing one's own chakra. It can attack and act. Because chakra is distributed evenly, Byakugan cannot see through it, but Mangekyo Sharingan can (after special training, like Madara seeing through Yamato's Wood Style clone). When a Shadow Clone is dispelled, the main body can gain the experience obtained by the dispelled Shadow Clone."

"Multiple Shadow Clone has no substantial difference from Shadow Clone, but the number is terrifying. Because each clone shares chakra evenly, using it by anyone other than someone with Naruto's physique might lead to death, hence it is a forbidden jutsu."

"System, how many points does it cost to exchange for Shadow Clone?" Chen asked the System.

"Answering Host: Shadow Clone Technique, Item Type: Skill, Item Level: B-rank, Required Exchange Points: 2000, Host Points insufficient, unable to exchange."

"Not enough points? Forget it, I'll use the Clone Technique from the Three Basic Ninjutsu Techniques for now. It's just in case Sasuke comes home early, there shouldn't be any problem. After all, Danzo isn't sending anyone to monitor me anymore, and with Sasuke's strength, not even genin level, he probably won't be able to tell." With no other choice, Chen used the Clone Technique to create a clone and had it lie on the tatami mat to sleep.

"Hmm, this is good. I won't have to worry about Sasuke discovering I'm not in the room anymore," Chen said, looking at the clone lying on the tatami mat. "Alright, I can go now."

Then, with a thought, Chen disappeared from the room. When he reappeared, he was already in the laboratory.

"Starting today, I'll practice chakra control!" Chen planned to train according to the method Kakashi taught in the original work, which was water walking and tree climbing.

"Ding! System has issued a mission: Host must master tree climbing technique within two days. Mission completion reward: 300 Points, Mission failure penalty: None, Accept?" The long-awaited mission notification sounded today, making Chen excited.

"Finally, a mission! How long has it been? I almost forgot that the System had a mission-issuing function!" Chen said excitedly, "Accept, of course, I'll accept. It's rare for the System to issue a mission, no matter how difficult, I'll accept it."

If you think this tree climbing training is simple, you are greatly mistaken.

Chakra is the energy ninjas need when using ninjutsu. It can also be made into threads to bind opponents or to cut through substances made of chakra.

Simply put, chakra is the energy required to use ninjutsu. This energy is roughly composed of: 1. Physical energy extracted from the body's cells, one by one. 2. Mental energy accumulated through much training and experience.

In other words, "ninjutsu" is the will to extract these two types of energy from within the body, refine them (this is called chakra extraction), and then activate them through the "hand seals" step!

Like Chen, although he can already use ninjutsu, he hasn't yet fully mastered chakra control. Chakra extraction means extracting physical and mental energy and then mixing them within the body. Depending on the ninjutsu to be activated, the extraction amount and the required blending will differ. Chen currently cannot use chakra effectively. Even if he can extract a large amount of chakra, if he cannot control the balance, not only will the effect of the ninjutsu be greatly reduced, but it may even lead to the ninjutsu being unable to activate. Moreover, because it wastes energy, it will also lead to the weakness of being unable to fight for a long time.

This tree climbing training is not ordinary climbing using hands and feet. It involves concentrating chakra in the soles of the feet, making the feet adhere to the tree trunk, and walking vertically upwards.

The purpose of this training is to gather the appropriate amount of chakra in the right place. The amount of chakra needed for tree climbing is very subtle, and the soles of the feet are the most difficult parts to gather chakra. In other words, if you can master tree climbing, you can theoretically learn any ninjutsu.

The second aspect of this training is to maintain the extracted chakra. Most ninjas extract chakra during combat. In such situations, controlling and maintaining chakra can be extremely difficult.

Therefore, to improve strength, tree climbing training is essential. Since this training cannot be conducted in the laboratory, Chen walked out of the laboratory and into the forest outside to begin his tree climbing training.

Chen came outside the cave and found a large tree with a very straight trunk: "Tree climbing training, I can't remember how Kakashi taught it. But concentrating chakra in my feet is certain. Let's try it first!"

With that thought, Chen began to form hand seals, then concentrated all his chakra in his feet, charged towards the tree in front of him, and then ran up the trunk.

However, after running only five steps, he broke a piece of the tree trunk, and Chen fell down.

"Was it because I used too much chakra?" Chen looked at the broken part of the tree, lost in thought.
