Under One Person: My comprehension is unmatched.

Several months later, the Tang Clan.

"Senior brother, is Zhang Yan still at Jishetang?"

Tang Bingwen, the head of the Tang Clan, put down the book in his hand and spoke to Tang Jiaren.

"Well, we fought the Hiei-zan ninja to a standstill, while he's been hiding away quite peacefully."

"But what can you do when they're the employer?"

The master sat in a grand chair, took a sip of tea, and said.

"Sigh, I wonder if it was right or wrong of me to break the Tang Clan's rules and let him learn Tang Clan techniques?"

Tang Bingwen, the leader of the Tang Clan, picked up the teacup, but put it down without drinking it.

"Heh, are you really going to let him join the Tang Clan? What for? To be the sect leader?"

"Besides, aren't the improved techniques he created excellent, greatly enhancing the strength of the Tang Sect?"

The old man chuckled and continued.

"After I came back, I thought about it for a long time and finally figured some things out."

"The world will eventually be at peace. We must leave some way out for our children. It's not good to always cling to old rules."

The Tang Clan leader nodded, indicating his agreement with his senior brother Tang Jiaren's statement.

Just then, a disciple of the Tang Clan knocked on the door of the study.

"Master, another Japanese man wants to see you outside the mountain gate."

The Tang Clan leader was taken aback upon hearing this, then looked at the patriarch, who chuckled.

"The fierce battles of these past few days have finally come to an end. Let's go take a look."

"It would be good to go and take a look; after all, guests are guests."

After saying this, the two followed the disciple out of the study. When they arrived at the mountain gate, they saw a person dressed in Japanese clothing.

Uncle Ying, who was standing to the side, was holding a letter. When he saw the gatekeeper arrive, he handed it to him and said something.

"This is a challenge to our Tang Clan, along with a list of names."

Tang Bingwen took the letter from Uncle Ying's hand, glanced at it, and then looked at the person who had come.

"This must be Mr. Tang Bingwen, the head of the Tang Clan."

The messenger spoke.

"We have fought against your faction many times, with both sides winning and losing. Now we really can't bear to see the two factions continue to suffer casualties like this."

"The feud between us must be settled. Master Tang, how about we each send ten men to settle this once and for all?"

"Fight to the death until one side has the last person alive, that counts as a victory."

"If I lose to Heshan, then we will never be enemies with the Tang Clan again, and we will never set foot on this continent again."

Tang Bingwen stared at the newcomer and spoke.

"What if our Tang Clan loses?"

"hehe."

The visitor smiled, pointed at Tang Jiaren and the sect leader, and replied.

"If the Tang Clan is defeated, we only need two things, and these two things can settle our grudges."

"That would be your two heads, Tang Clan leader and Tang Jiaren."

Tang Jiaren and the sect leader exchanged a glance, then smiled, and the sect leader spoke.

"Trading our two old men's heads for everyone's peace is a really good deal."

“But the mountain caves in the northern border are too far away, so we need to choose the place for the duel between the two sides.”

The other party chose this place not only to cut off the Tang Clan's escape route, but also because it was where Zhang Yan rose to fame, so they weren't worried about him not coming.

"Heh, no matter how far away it is, it's still your territory. We're the ones playing away. We should be the ones worrying."

"There are only the ten people we selected there, along with some elders from Bihe Mountain."

"If you're not comfortable with this, you can invite some important figures to be witnesses. We don't mind."

The newcomer immediately began to mock him, seemingly unconcerned about his own life or death.

Tang Bingwen remained unmoved by the newcomer's mockery and calmly replied.

"Integrity is very important. Even if you are our enemies, we still have the most basic respect for you."

"Thank you for the Tang Clan's respect."

After the visitor finished speaking, he stretched out his arms and continued.

"Let me introduce myself. I am Wakasa Chubei, one of the ten. I look forward to fighting to the death with you all."

"Alright, the Tang Clan accepts the challenge. Let's discuss the details further, and once it's signed, you can take it back."

The Tang Clan leader looked at the name of the challenge letter and asked another question in confusion.

"This Erli Jushi..."

"That person, he's our new ninja leader."

Wakasa Shohei spoke up.

"Okay, I understand. Go down the mountain and rest. I'll have someone deliver the challenge to you later."

Wakasa Shobei turned and went down the mountain. Before he had taken more than a few steps, he saw two more people coming down the mountain. They were Zhang Yan and Lü Ci.

"What are these Japanese doing here at the Tang Clan?"

Lu Cixian wanted to bite any Japanese person he saw, regardless of whether they were aliens or not.

"Isn't the challenge in the sect leader's hand? Didn't you see the letter?"

When Wakasa Shohei saw the two of them, his gaze naturally fell on Zhang Yan, and he spoke.

"Zhang Yan?"

When Zhang Yan heard his name called from the other side, he immediately went forward with great enthusiasm.

"Hello, Erli Jushi, I am Zhang Yan."

Upon hearing Zhang Yan's words, the Tang Clan leader and the others all turned their gazes to the two of them.

Wakasa Shobei broke out in a cold sweat and took a few steps back, but Zhang Yan still managed to grab his hand.

He had no choice but to shake hands cooperatively and say something.

“I am not Nichirikoji, my name is Wakasa Shohei.”

"Oh, sorry, I only heard the name of Erli Jushi when I was going up the mountain."

Zhang Yan released his grip and continued speaking.

"I got a little excited when I heard that it was a new ninja leader, after all, this is only the second time I've seen a living ninja leader."

"Um, Mr. Zhang Yan, if there's nothing else, I'll head down the mountain now."

Wakasa Shobei felt a chill run down his spine when he saw Zhang Yan's gaze, and turned to leave after speaking.

"Okay, okay, I'll send the letter to you in a bit."

The man didn't even turn his head; he went straight down the mountain.

"Brother Zhang Yan, you'll scare him away like that."

Lu Ci looked at the disappearing figure and spoke.

"No, as long as they are still within Tang Sect territory, they won't run away."

Just as Zhang Yan finished speaking, the old man added another sentence.

"Heh, he can't escape either, until he receives our challenge."

The master's meaning was clear: now that he had come to the Tang Clan, he wouldn't leave without receiving a challenge letter, and it wouldn't be difficult for the Tang Clan to keep him there.

Lu Ci followed Zhang Yan up the mountain, and after seeing the list, he immediately asked to join the ten-person deathmatch.

The Tang Clan leader thought for a moment and then spoke.

“Young Master Lü, since Zhang Yan has brought you here, and you bear a deep-seated blood feud, then we can take you there.”

"But if you're fixated on one-on-one combat and personally killing your enemy, that won't work."

Lu Ci fell silent for a moment, then revealed a mad dog-like expression and spoke.

"Master, don't worry. In the end, he was the only one who didn't die by my hand. We'll accept it if we get to eat a few bites of his corpse and take it back with us."

The Tang Clan elder looked at the challenge letter in the sect leader's hand and spoke.

"Master, wasn't your decision this time hasty? What if it's a trap?"

"hehe."

The patriarch, Tang Jiaren, spoke up.

"This is a trap."

"Their strength has been severely weakened by the fighting during this period, and their new ninja leader is thinking of a fight to the death."

"It is estimated that besides those ten people, there should be other super-powerful superhumans who want to completely destroy the Tang Clan through this battle."

At this point, the old man looked at Zhang Yan and continued.

"Also, Zhang Yan, you know many people in the military, so you can keep an eye on the situation of the Japanese army."

After hearing the master's words, everyone fell into deep thought. This was not a battle of ten against ten; it was a desperate fight to wipe out an entire family.

"Hehe, sir, you don't need to guess anymore, what you said is all true."

"Actually, when I met that Japanese man just now, I already knew that he was the new ninja leader and that he had two souls."

As Zhang Yan spoke, he extended a finger, from which faint blue energy appeared.

“I just planted an idea in one of his souls: gather all forces and eradicate the Tang Clan.”

"I reckon they're arguing right now. While I'm delivering the message, I'll talk some reasoning with the other soul."

Everyone was startled when they heard Zhang Yan's words.

That person was actually the new ninja leader, and he had two souls. Wasn't he afraid of dying when he came to the Tang Sect?

Also, what does it mean that Zhang Yan planted the idea? Does he now have the ability to change people's thoughts through various means?

Zhang Yan glanced at Lü Ci and spoke.

"The results of my months at Jishetang are not perfect yet, but they are sufficient for now."

Zhang Yan finally comprehended the blue hand in Shuangquan's hands through medical skills, witchcraft, and spiritualism, but the problem of bloodline was still not solved, and he still did not have a red hand.

The Tang Clan leader showed no anger at Zhang Yan's actions and spoke up.

"Now that this thorn that has been hidden for so long has finally come out, let's pull it out by the roots."

"For this operation, the Tang Clan will send ten people openly, but most of them will go secretly."

Zhang Yan nodded and spoke.

"As for the ten men and the army, the sect leader doesn't need to worry. The main concern is the ninjas outside the area. We can't let them escape."

Upon hearing this, the master laughed heartily.

"Kid, look at you, thinking you can take on ten at once?"

"Oh? No big deal, hehe, it's not like we haven't fought before..."
