"It's you!" The man with short beard stood up, "Long hair. Why did you bring him here? Do you know that this guy ruined my plan before!" His plan was to assassinate the third prince Zhou Jian.

"I have no choice. I can't beat him." The long-haired man explained.

"Oh, I see." The short-bearded man had a knife beside the bed, and he reached for it quietly. "Do you think we can kill this guy together?"

"I don't know, I think so." The long-haired man spoke to Wang Xiaohai before just to let Wang Xiaohai relax his vigilance. After they finished speaking, they attacked at the same time, and their target was Wang Xiaohai!

Wang Xiaohai used his elbow to block the long-haired man's claw attack, and then kicked the short-bearded man.

"Bang——"

Wang Xiaohai used force to defeat the opponent's cleverness. His elbow struck the long-haired man, cracking his wrist and instantly rendering his right hand numb. The short-bearded man saw Wang Xiaohai kicking at his wrist, but he didn't flinch, but instead increased the speed of his blade. He intended to trade his hand for Wang Xiaohai's life. He was ruthless to himself, and even more ruthless to his enemies!

Wang Xiaohai didn't intend to fight this guy to the death, as he would definitely suffer a loss. Even if it meant exchanging one hand for the other person's life, Wang Xiaohai was unwilling to do so.

"go!"

Wang Xiaohai stepped back to avoid the short-bearded man's long knife, then kicked the bed board. Half of the moldy bed board rose up like a wall, blocking the short-bearded man and blocking his entire sight.

The short-bearded man swung seven swords in the air, cutting the bed in front of him like cutting fruit. When he was about to slash at Wang Xiaohai with the eighth sword, he found that there was no one in front of him.

“Oh no!”

The long-haired man rushed straight towards the short-bearded man. At the moment of contact, Wang Xiaohai flashed out from behind the long-haired man and stabbed the short-bearded man with a dagger. This dagger was as fast as lightning and pierced directly into the short-bearded man's body.

Fortunately, the man with short beard moved a short distance at the moment when the dagger approached, thus avoiding being pierced in the heart.

"Long-haired, you bastard lied to me. There is no way we can be his match!" The man with short beard was defeated in a few moves. He decided to escape. He turned around and kicked a block on the ground, revealing a hole, and then jumped down.

The man with short beard saw that Wang Xiaohai was with someone and his movements were definitely not as fast as his, so he had the chance to escape!

Wang Xiaohai did not chase the man with short beard, but caught the man with long hair.

"Please spare my life!" begged the long-haired man.

"I just begged you, will you let me go?" Wang Xiaohai was unmoved. "You will definitely kill me. So, please give me a reason why I can't kill you, and I will give you a chance to defend yourself."

"You didn't chase my friend and let him go. Most of the time, he was the one who attacked you. According to the theory of fairness, you should let me go too." The long-haired man said, "And I introduced this passage to you. I swear, on my divinity - as long as you let me go, I will never attack you in this life!" His oath was like fart. He was obviously no match for Wang Xiaohai. Fighting with Wang Xiaohai was tantamount to suicide. Of course, he would not fight with Wang Xiaohai.

Wang Xiaohai pulled out the dagger and the long-haired man took a step back.

"Your hand is injured. All you need to do is swear one more oath, and I'll let you go," Wang Xiaohai said. "You swear to do your best to investigate the matter of Concubine An and Princess Shu's mother within ten days. You need to find evidence, and you can figure out the solution yourself."

"Okay, I swear." Although the long-haired man did not know Concubine An and Princess Shu's mother, he had no capital to negotiate with Wang Xiaohai, so he could only swear according to what Wang Xiaohai said.

After the long-haired man swore, he staggered away into the darkness. Wang Xiaohai did not chase him.

"Why did you let him go?" asked Princess Shu.

"Killing him would gain nothing, but keeping him alive and working would maximize his value," Wang Xiaohai said. "If someone dine-and-dine in your restaurant, would you beat them up and throw them out, or let them work for free for a month? No food, no room, no pay."

"But are you so sure that the other party will keep their oath?" Princess Shu felt that Wang Xiaohai had been deceived. Many people swore an oath and then forgot about it.

"I believe he will keep his oath." Wang Xiaohai didn't want to explain. "Hurry and leave this underground passage. Don't give the other party time to block the exit and set it on fire."

The two hurried into the underground passage.

The passage was winding and completely dark, so dark that you couldn't see your hand in front of you.

"The other party often takes this road, so they are fast." Wang Xiaohai groped his way along the wall and slowly moved forward, always paying attention to whether there were any traps under his feet.

"Teacher Wang Xiaohai, I feel like there's a snake under my feet, it's limp." Princess Shu said in a trembling voice in the dark corridor.

"It's okay. You didn't step on the snake, but on my shoes and feet." Wang Xiaohai said, "Just follow me carefully."

There was a faint smell of blood on the road ahead, which disappeared after a few hundred years. Wang Xiaohai guessed that the man with short beard had bandaged his wounds.

"Is there a fork in this tunnel?" Princess Shu said. In the darkness, humans always have strange ideas. "What if we walk here for a year and still can't get out, and we keep taking detours? I don't want to die in this underground tunnel."

"No, even if it's pitch black, I can still determine the direction by feeling, and I can still remember the path I have taken." Wang Xiaohai said, "Geniuses can pass through the maze with their eyes blindfolded. Besides, this road was originally built by the imperial palace for escape, so it would not be built as a maze to harm itself. There is only one path!" Wang Xiaohai believed in his own reasoning and judgment.

Sure enough, an hour later, a faint white light appeared in front of the two people. That light seemed to be the only star in the starry sky, guiding the direction of their progress.

The light spot grew larger and larger, from a sesame seed to the mouth of a bowl, then from the mouth of a bowl to a wheel, and finally from the wheel into a two-meter-high hole. Behind the hole was a wall made of rubble, and moonlight sprinkled in the cracks in the stones. A gecko heard the human voice and quickly drilled into the gap in the stone.

The starlight sprinkled on the edge of the cave, illuminating countless messy footprints above. Wang Xiaohai and Princess Shu walked out of the cave.

"Is this the bottom of the well?"

Princess Shu looked up and found that they were under a dry well, the well mouth was more than four meters away from where they were.

"This guy climbed up using the rope!" Wang Xiaohai saw a circle of black hemp rope at his feet. "He cut the rope after he got up."

"What should I do now?" Princess Shu tried to grab the edge of the well and climb up, but there was no support. She slipped down after just two steps. "Do you want me to push you up?"

"No need." Wang Xiaohai picked up the well rope at his feet, "I can jump up, and then I will lower the rope to pull you up." As he said that, Wang Xiaohai grabbed one end of the hemp rope, jumped up, stepped on the edge of the well and flew to the other side, then stepped on the other side of the well again, and jumped directly onto the well like an eagle.

"Come up!" Wang Xiaohai lowered the hemp rope, and Princess Shu immediately grabbed it tightly and wrapped it around her hand. Wang Xiaohai exerted force with both hands and quickly pulled Princess Shu up.

"Finally out!" Princess Shu looked around and found that she was in the courtyard of a wealthy family. It was surrounded by high walls, and it was difficult to see that there was a dry well here.

"It's probably the home of the antique shop owner, the descendant of that guard." Wang Xiaohai pulled Princess Shu through the empty houses and came to the bustling street.
