The poison of the demon cod poison is strong, it can poison the lives of many martial arts masters on a large scale in a short period of time, Qin Feng saw that the existence of this poison had seriously threatened the lives of him and the martial arts people, so he decided to investigate the matter to the bottom of the matter.

The maker of the magic cod poison is Luo Tianxing, the drug king of the Western Regions, once Luo Tianxing was arrested for drug involvement on the way to visit relatives in Chang'an, but fortunately he was rescued by a strong man named Qiulin, so as to avoid Luo Tianxing's imprisonment this time.

Qiu Lin is seven feet tall, with thick eyebrows and big eyes, a lean and powerful body, and his whole body is flexible and agile.

Luo Tianxing saw that Qiu Lin's chivalrous liver and courage helped him, so he accepted him as an apprentice, and passed on to him various poisoning and antidote methods, and after Luo Tianxing's death, Qiu Lin joined the Five Poisons Sect and became the left protector of the Five Poisons Sect.

"Report, report to the general, the Xinyou Inn has now been blocked by our army, please go and investigate the corpse of the person who was killed last night!" The soldier hurriedly reported the incident to Cheng Yanjin.

Cheng Yanjin frowned suddenly, and asked in surprise: "Are they all the strong men who participated in the ring competition yesterday?"

"A total of 28 people died, all of whom were strong men in the list of 30 people!" Vice General Zhu, who was beside Cheng Yanjin, explained.

"Come with me to investigate the scene, if the Tang King knows about this matter, he will blame me!" Cheng Yanjin rode on a fast horse and immediately rushed to the Xinyou Inn.

Cheng Yanjin arrived at the door of the Xinyou Inn and saw that the corpse in the inn was lying in a mess, but the tables and chairs in the inn were all upright and neat, and there was no trace of a fight, obviously he was poisoned to death.

"Who did it, unknowingly poisoned under the noses of many masters, this person must be a master of poisoning?" Cheng Yanjin pondered at the door of the inn.

At this time, there was a footstep sound of "pop papa" on the roof of the inn, and three short daggers suddenly attacked from the height of the roof, and the target of the daggers was Cheng Yanjin, the general of the Tang Left Guard.

At this critical moment, a sword suddenly blocked in front of Cheng Yanjin, helping him block the three deadly short daggers, and the sword was engraved with three words "Xianyun Sword".

"It's too late to be rescued, please forgive the general!" Qin Feng turned around and flew in front of Cheng Yanjin.

Cheng Yanjin looked at the young man in front of him, and was very grateful in his heart, gently patted his shoulder twice, and gave him a thumbs up.

After a night's hard work, Qin Feng had basically found out the clues to the poisoner of this demon cod poison.

He said loudly to everyone present: "This poison must have been caused by a person who has achieved light achievements, and this person knows poison very well, and it may be difficult to deal with him."

Qin Feng looked at the poisoning method at the scene, the poisoner was definitely not poisoned before the twenty-eight masters drank, because the poisoner was not sure which pot of wine the twenty-eight masters were drinking at that time.

The poisoner's method of poisoning at that time was to wait for these people to drink until they were half-drunk and delirious, and then flew through the air with peerless light skills, dripping the poisoned water prepared in advance from the roof, and unknowingly dripped into the wine jar, and finally left the scene with rapid light skills.

Qin Feng knew the poisoner's methods well, but the poisoner's light skills were high, and he couldn't judge the identity information of the poisoner in a short period of time.

Suddenly, one of Cheng Yanjin's heralds got a very important piece of news.

"Report, report to the general, we will enter the Xinyou Inn to search for clues, and we have found an important clue, please take a look at it!" The herald handed the small note he had found to Cheng Yanjin.

Cheng Yanjin opened the small note and saw that only eight words were written on the small note, "The Poison King of the Western Regions, subvert the Tang Dynasty."

Suddenly, Cheng Biting Jin rushed to his brain with anger, and he threw the small note in his hand to the ground in an instant, and scolded casually: "The Poison King of the Western Regions, it's the other way around."

When Vice General Zhu saw Cheng biting the gold, he immediately ordered the whole city to be blocked and arrested Luo Tianxing, the drug king of the Western Regions.

As for Qin Feng, he always had a skeptical attitude towards this matter, and always felt that this matter was not so easy to conclude.

Qin Feng picked up the small note that Cheng Biting Jin threw on the ground, and always felt that the eight words on the note were not quite right, and it might contain another meaning.

"Since he is the Poison King of the Western Regions, it must be written in the Western Regions, so why are all these eight characters in Chinese?" Saying that, Qin Feng handed the small note to Cheng Yanjin.

Cheng Yanjin asked with some hesitation: "Zhuangshi, what do you mean"?

Qin Feng stood up and said: "The meaning of the following is simple, the Western Regions Poison King must be fake when he writes Chinese, someone must be pretending to be the Western Regions Poison King, or someone related to the Western Regions Poison King."

At this time, Vice General Zhu beside him suddenly remembered something.

Vice General Zhu recalled: "Luo Tianxing, the poison king of the Western Regions, once accepted an apprentice, named Qiulin, and this matter spread in the martial arts that year, but after many years, Qiulin and Luo Tianxing have disappeared, will this matter be related to Qiulin."

Cheng Yanjin lowered his head and pondered, while Qin Feng nodded, but the two of them said something in unison.

"How do we go to find Qiulin now?" Vice General Zhu asked.

Cheng Yanjin couldn't make up his mind for a while, and he and Vice General Zhu stared at each other with big eyes.

After being silent for a long time, Cheng Yanjin and the others felt the pressure to arrest Qiu Lin, after all, Qiu Lin was not an ordinary person, but an apprentice of the Western Regions Poison King.

Qin Feng looked at the two people in front of him and couldn't come up with the slightest idea of arresting Qiu Lin, so he slowly spoke: "Otherwise, since the general has blocked all the exits of the entire Chang'an City, Qiu Lin will not be able to escape from the general's palm even if he inserts his arm, then we only need to strictly investigate at each exit, and beware of Qiu Lin from escaping in the clothes of the people."

Cheng Yanjin and the others were in an uproar, and clapped their hands vigorously: "The strong man's plan is very good."

But at this time, Vice General Zhu was worried, and took the small note and looked at it again and again.

Vice General Zhu then asked: "Zhuangman, we have never seen Qiulin himself, how can we recognize which one is Qiulin?"

Qin Feng didn't know how to answer Vice General Zhu's question, so he just buried his head in a wry smile on the side.

As soon as these words came out, Qin Feng was embarrassed, in order to avoid the scene being too embarrassing, Cheng Biting Jin sent Qin Feng to the east gate of Chang'an City to guard to prevent Qiulin from escaping, and sent Vice General Zhu to the south gate to guard it, and he guarded the west gate, while the north gate was closed normally.

Cheng Yanjin immediately blocked the Xinyou Inn, sent people to carry away the twenty-eight corpses, and then went all out to guard the three gates and arrest Qiulin.
