The so-called strange things have their reasons.

Bai Zhi nodded her head, told him to step back, and continued to stare quietly.

The second servant came in and bowed to Bai Zhi, then said: “Miss, Xiao Si has a bad appetite on weekdays. He can only eat a bowl almost a day, but he ate three bowls of rice today. It’s so weird. He eats a lot, but didn’t even burp after a full meal.”

The third servant came in. He also said that the person he was monitoring suddenly ate a lot, and ate again less than an hour after the meal. He was caught stealing food in the kitchen.

The situation of the fourth person was similar. These four people have a common feature, their complexion was not good, they were dry and yellow.

After asking them to retreat, Bai Zhi fell into deep thoughts, when suddenly she heard the sound of the door curtain being lifted, then a familiar figure fell into her eyes.

“Why did you come? Didn’t you say you have work to do in the imperial court?”

Hu Feng frowned and sat down next to her. His face looked gloomy.

“What’s the matter? Did something happened?” When Bai Zhi saw him like this, her heart skipped a bit.

Hu Feng sighed and told her what happened in the imperial study room the day before yesterday.

Bai Zhi asked in surprise: “So, the emperor drank it?”

Hu Feng nodded his head, then took out a medicine packet, and handed it to Bai Zhi: “This is what I managed to get. Chu Feng brought five packets of medicinal tea into the palace. This is one of them. Imperial Father has already drunk two packs.”

Bai Zhi immediately removed the medicine packet, put on clean gloves, and picked out the licorice.

The licorice looked normal, she didn’t find anything strange. The appearance and scent were nothing unusual. There was nothing doubtful.

But this thing was clearly problematic. So how can there be no doubts?

“What can you see?” Hu Feng asked.

Bai Zhi shook her head and was about to say no. When she suddenly remembered what the four people had just reported, the four people who had used Luan Pharmacy Shop’s licorice had the same characteristics. They ate a lot of greasy food.

What does this mean?

If they really have Gu worms on them, then it’s not them who wanted to eat these greasy things, but by the Gu worms.

In other words, Gu worms not only like to eat human blood but also like to eat oil.

Thinking of this, she had an idea.

Bai Zhi asked the maidservant to bring a bowl of freshly boiled lard. The freshly boiled lard was very clear. She then put it in front of the window with a cold breeze. Soon it quickly condensed into a bowl of white creamy lard.

Hu Feng looked at it and asked curiously: “What is this?”

Bai Zhi said: “I don’t know if it’s useful, but let’s try it!”

The surface of the lard in the bowl was very smooth. Bai Zhi put two slices of licorice on top. The licorice was dark in color, while and the lard was white and smooth. It looked like a ghost’s face with a pair of hollow eyes.

Bai Zhi then ordered the maidservant to get a knife. When she was about to cut her finger, Hu Feng grabbed it: “What are you doing?”

Bai Zhi looked at the bowl on the table and said, “If you want to draw out this Gu worm, using lard alone might not work. We also need to use blood.”

Hu Feng quickly said: “How can you use yours, use mine.”

Bai Zhi immediately shook her head: “No, no, you are a prince, you always go back and forth in the imperial palace. If the emperor sees your injured finger, I’m afraid he’ll get the wrong idea.”

The corner of Hu Feng’s mouth twitched: “He won’t care about this stuff. Don’t talk about it, just use mine.”

He said and was about to cut his finger. But at this moment, Zhou Awu, who was next to him, cut his finger. When his blood dripped into the bowl, Zhou Awu grinned: “Use mine, I have a lot of blood.”

Now that Zhou Awu cut his finger, Hu Feng and Bai Zhi were no longer interested to fight. She let him took the knife.

The three focused their eyes on the bowl and kept staring at the blood and the two pieces of licorice.
