"This is a nerve numbing acupoint in the human body." Gu Ziming slowly said as he looked at the position of the needle.

Sihan was immediately shocked. She didn't know much about acupuncture points. "What do you mean by that?"

Gu Ziming slowly and similarly shouted an explanation." In other words, if someone were to insert a silver needle into this part of my father's head, it would cause my father's nerves to go numb, and his hands and feet would not be able to obey his commands. " After pausing for a moment, Gu Ziming continued, "But my father's skills are extremely high. Normal people can't even get close to him, let alone stick a needle into this acupoint on his head." This was also the reason why he had always believed that the old general committed suicide. The old general's martial arts was strong, so few people in the entire Qi Kingdom were his match. At that time, the old general's room was clean and tidy, with no traces of a fight at all.

Sihan gently placed the old general's skull on the bed, then followed the clavicle and Adam's apple bones to carefully examine them. Suddenly, she found a small black dot on the old general's sternum. She turned around and took out a silver needle from the small package that she had prepared beforehand. She placed it on the black dot on the old general's sternum and picked it up. The tip of the silver needle was black, meaning the old general had been poisoned before he died.

Everyone's eyes widened in shock when they saw this scene. They didn't expect the old general to be poisoned before he died.

"How can this be? The old general had been poisoned, how could no one have discovered it? Shouldn't the blood from poisoning be black? If it's black blood, it's impossible that no one would not realize that the old general was poisoned! " Bing'er frowned as she looked at the old general's skeleton.

"No, it should be a chronic poison, and it should be under the control of the old general. The poison is about to be eliminated. Therefore, the old general's blood was red instead of black. This poison was completely harmless to the old general's body. Furthermore, this poison has probably been in the body of the old general for a long time, and has nothing to do with the death of the old general this time around. " Sihan explained to Bing'er.

"So the old general killed himself?" Bing'er could not help but ask Sihan. The old general was perfectly fine except for a needle on his head, which could be used to numb his nerves.

Sihan replied confidently, "Of course not, the old general was indeed killed by someone." She then turned to look at Gu Ziming, "Young General, if a needle were to quickly pierce your heart, would it cause your heart to stop beating, and cause you to lose the ability to resist?"

"Yes." Then, he explained to Sihan and the others, "No matter how high your martial arts are, if you're stabbed by a silver needle into your heart meridian, your heart will stop beating for a short period of time. During that time, you'll be slaughtered, but if you're an expert, then it won't be long before he can use his internal energy to force the silver needle out of your body." "This is the principle behind the old general's death." Sihan continued Gu Ziming's words.

Everyone still looked at Sihan in confusion. They still didn't understand the meaning behind Sihan's words. Only Gu Ziming understood the meaning behind Sihan's words. He lowered his gaze and looked at the small black dot in front of the old general's breastbone. That spot was precisely where the old general's heart veins were located. At the same time, he knew how the old general had been killed. He nodded to Sihan and walked out of the room.

Seeing that the others were still confused, Sihan calmed herself down and told them once more. "First, someone inserted a silver needle into the old general's heart when he relaxed his guard, causing him to temporarily lose consciousness and be killed. The killer was afraid that the old general's internal energy would force the silver needle out, so he stabbed another silver needle into the old general's skull to numb his nerves. Then he carried the old general onto the bed and fiercely stabbed the dagger into the old general's chest, covering the needle hole and at the same time causing the old general to commit suicide.

"So that's how the old general was killed." Bing-Er looked at the old general's skeleton with regret and said angrily, "The old general is so pitiful. Not only was he killed so cruelly by the murderer, he was even burned to death. That murderer is too heartless!"

"Fortunately, the murderer burned the old general's body, leaving only his skeleton behind. Otherwise, I don't think I would have been able to find out the real cause of death of the old general." Sihan looked at the old general's skeleton and said.

"I'm afraid the murderer would never have thought that he was wrong this time." ZhiNing couldn't help but snort coldly. Sometimes, it wasn't good if one was too smart.

At this moment, Gu Ziming entered the room from the outside. He held a silver needle in his hand. He gave the silver needle in his hand to Sihan. "I found it in my father's room."

Sihan took the needle and looked at it. Indeed, there was a bit of black on the tip. From this, it could be seen that this silver needle was the needle that the old general had forced out of his body. This also meant that her judgement was correct. The old general had been killed just like she had predicted.

Gu Ziming carefully collected the old general's corpse, wrapped it in a bag, and disappeared into the night.

The crowd looked at Gu Ziming's departing back with great sympathy. The old general had been fair and square all his life, but he had never imagined that he would end up like this.

It was only when Gu Ziming's back had completely disappeared in front of them that Sihan turned to look at Zhining, "Zhining, tell us what you think."

After standing in the cell for a long time, she felt a little tired and needed some rest, "The old general's skills are very high, so very few people can get close to him. Even if they could get close to him, they might not be able to pierce a needle into his body. From this, it can be determined that the person who stabbed the silver needle into the old general's body must be extremely familiar with the old general, and he can also help the old general relax his guard. The most important thing is that person's skill is very high, he can accurately stab the silver needle into the old general's heart when the old general removes his guard. There were no signs of a fight in the old general's room, which showed how skilled that person was.

"But how many people are familiar with the old general? How are we supposed to investigate?" It's no different from looking for a needle in a haystack. " Bing'er continued to speak.

"No, since they've killed someone, they will definitely leave behind evidence. Let's search the old general's room to see if there's any evidence."

As soon as Sihan finished speaking, ZhiNing stood up from her chair and walked towards the old general's room. Sihan and Bing'er looked at each other, then shook their heads.

When they arrived at the old general's room, Zhining had already been looking for valuable evidence everywhere.

Sihan, Bing'er and Xiao Cui entered the room together. The four of them split into two groups and started searching for evidence.

However, when the sky started to brighten, the four of them couldn't find any evidence.

Bing-Er walked over to the table and sat down on the chair. She clenched her fists and lightly punched her calves. She had been tired out these days.

Xiao Cui walked to Bing-Er and squatted down to hit her leg.

Bing-Er pulled back her calves without thinking, "I'll do it myself." She was not used to being served like that.
