"That's right, that's what we do." Zhao Xiaosi lowered his head and said a little dejectedly.

"Tell me, why did you kill so many people? And how did you do it without revealing a trace? Nan Liyan said indifferently.

"Why kill so many people? It's just to cover up the treasure, and the first hunter who found the treasure actually wrote a letter to inform his family after discovering it. Thinking of asking your family to help him hold the pen treasure together, after he said that he had found one who had gone to Longping Mountain to find the treasure, we thought that as long as we killed him, it would be foolproof, but we missed the calculation that he would send a letter back. Most of the people who came later were the ones who heard him say that there was a treasure in Longping Mountain in the inn that day. People are greedy by nature, so they die because of their greed, and they also die as they deserve. Others were relatives of the hunter who came to find out why he was killed. Zhao Xiaosi said that his face was all indifferent, only a little unwilling, those who were unwilling were just because of the chagrin and shame that Gu Annuan saw through the plan.

"As for how you did it, you'll have to ask him." Zhao Xiaosi glanced at the beggar lightly and signaled that he knew the truth.

"Hehe," the beggar tugged at the corners of his mouth, his eyes full of disdain, as long as he had this ability, how could he not find a clue? The reason why Gu Annuan and the others couldn't find clues this time was just that Zhao Xiaosi had cleaned the room.

But to be honest, the intelligence of Gu Annuan and others is indeed beyond the reach of ordinary people.

"I just used the simplest Gu worm, that kind of Gu worm bites people for half an hour before it kills, and the Gu poison will disappear two hours after it enters the body, so it's strange that you can find evidence, as for the thing you found similar to spider silk, it is not cloth, but the saliva of Gu worms, what kind of clothes and fabrics do you say, it's really laughing to death." The beggar scoffed.

"I see, no wonder." Gu Annuan nodded suddenly in understanding.

"Miss, I think the Gu worm they are talking about should be this." Yinchuan took out a wrapped handkerchief from his arms, and when the handkerchief was opened, there were several dead insects lying inside.

The bugs were nothing special, they were the size of a beetle, and they were pitch black.

"How did you have this?" Gu Annuan glanced at Yinchuan in surprise.

"This is the bug that the shopkeeper released to attack us, I picked up a few by the way after I got killed, I want Miss to see what kind of bug this is, how can it attack people." Yinchuan shrugged his shoulders and said.

Nanying glanced at Yinchuan, and didn't seem to know when Bai Yinchuan was so careful, so she said that after they caught the shopkeeper, Yinchuan was still tinkering in the room for a while, what was he doing, it turned out that he was picking up the corpses of these little bugs.

"How did you know how to use Gu worms?" Nan Liyan's eyes were cold and he looked at the beggar who was kneeling on the ground.

The technique of Gu poison was strictly forbidden in the previous dynasty, and the emperor of the previous dynasty sent troops to attack the northern frontier many times.

It is because Gu art was very popular in the previous dynasty, many people learned this technique and harmed people's lives, and even the concubines in the palace of the former dynasty used this kind of thing to frame others.

The most serious one was because a prince used the Gu poison technique to murder the emperor, and the emperor was furious, raided the prince's house, and began to strictly prohibit anyone from learning to use Gu poison, if there was a violator, the nine clans would be affected.

This move was carried out until the current dynasty, in order to fear that someone would use this method to harm others.

"I learned it from a wandering warlock, and he said that this thing could save my life at a critical time." Seeing that the situation is already like this, the beggar might as well confess and fight for a glimmer of life.

"It's a pity that you used life-saving means to harm people." Gu Annuan shook his head, and then stopped talking.

"Come on, press them down and put them on death row, behead them after the autumn, and order the treasures of Longping Mountain to be taken down and handed over to the treasury." Nan Liyan spoke lightly, his tone cold and extremely cold.
