The evil concubine plays the devil emperor

Chapter 192 The Art of Gu Poison
Following the sound, everyone found an old man walking slowly from behind. Obviously, the coughing sound was made by him.

For the old man who came out from behind, Bai Xiyan and the others had a flash of astonishment in their eyes.

Where did this old man come from?

Although they were discussing, they didn't put all their mental energy on the discussion, and some of them were still paying attention to the movement around them.

Even so, they did not find the existence of the old man.

If it hadn't been for the sound of his coughing, they would not have found him.

How much has he heard?
How long has he been standing behind them?

If he wanted to kill them, their heads would already be dead by now.

Because, they didn't find out how he appeared at all.

Such elusiveness is hard to guard against.

Fortunately, he did nothing.

"Grandpa, what do you do?" Bai Xiyan looked at the old man with innocent eyes, no matter how cute he looked.

Bai Xiyan is extremely beautiful. If she hadn't been acting steady all along, no one would really treat her like a little girl.

In fact, she was really a little girl, a 13-year-old girl.

Dazed by Bai Xiyan's smile, the old man said with some embarrassment, "I'm very interested in hearing you talk about the art of poison poisoning, so..."

The more he talked, the more embarrassed he felt, he had never done such a thing of eavesdropping, but when Bai Xiyan said the poison, his curiosity overcame everything, and he kept listening.

He didn't have to come out until his nerves were touched after he said the four words 100 years ago.

"Could it be that the old man knew about the Gu poison 100 years ago?" As soon as Bai Xiyan said this, the old man looked at Bai Xiyan in surprise, and a bright light flashed in his eyes.

He didn't expect this girl to be so smart. He didn't say anything, but she guessed it directly.

That's right, he did know and even participated in it, but he didn't find a way to get rid of the poison.

"Hehe..." The old man chuckled, and his smile was full of cunning.

He was waiting for Bai Xiyan to ask him to speak out, but unfortunately, Bai Xiyan didn't move at all, not even showing any signs of speaking.

On the contrary, he couldn't bear it anymore, because what Bai Xiyan said next completely touched his heart.

"Huo Xingyun, I need to check your father's pulse to know his specific situation. If it's just Gu poison, I should be able to cure it!" Bai Xiyan didn't say anything, if he couldn't solve it, it would be too embarrassing.

"What? You said you can detoxify it, how can you detoxify it?" Before Huo Xingyun could speak, the old man grabbed Bai Xiyan's wrist and looked at her excitedly.

"There are records in ancient books on how to detoxify Gu poison!" Of course, Bai Xiyan couldn't say that the way to detoxify Gu poison came from the God of Medicine.

If she said this, people might think she was a fool.

"Which ancient book?" The old man's expression became more and more excited, and his eyes seemed to be shining when he looked at Bai Xiyan.

"Forgot!" As soon as the three words fell, the old man let out a cry, very disappointed.

He thought that he was lucky enough to be able to see the ancient book on detoxification, but now, his hope was in vain.

However, soon, he was revived again with full blood, and his eyes turned to Bai Xiyan.

He can solve it, so just follow her.

Thinking of this, the smile on the old man's face became even stronger!
