When Lin Zhan saw the bags of silver charcoal outside, his eyes rolled around and then he left.

After knowing that Lin Zhan had left, Tang Yu's face was filled with pride. "If you don't want to be my friend, then we can only be my enemy."

After returning to her own yard, Lin Zhan took out the token given to her by Murong Hui from under her pillow, and then summoned Qingzhu, the guard given to her by Jun Beiqi.

He asked Qingzhu to place the token at the agreed location, and at night, Murong Hui arrived as promised.

"Little girl, what do you want from me so soon?" At this moment, Murong Hui was wearing a black dress with a red background, which made her look very sexy. There was also a red mole between her eyebrows, which added a bit of feminine charm to her look.

Even Lin Zhan couldn't help but be surprised. "Why do you seem like a different person? You seem different from before."

"Why is it different?" Murong Hui slowly walked towards Lin Zhan, and then actually lifted Lin Zhan's chin with his fingers.

A pair of tender and silent eyes looked at Lin Zhan just like that, which made Lin Zhan get goose bumps and shudder. He then pushed Murong Hui's hand away.

"Your fingers are so cold." Lin Zhan said with his tongue out. Murong Hui actually giggled and his body kept shaking.

This gave Lin Zhan goosebumps again, and at this moment, a cold and familiar voice sounded in the darkness.

"That's enough Linglong, back off."

As soon as the words came out, the real Murong Hui walked out from the darkness. Lin Zhan looked at the two Murong Hui in front of him and couldn't help but widen his eyes.

"Two Murong Huis, what's going on?" Lin Zan looked at the two people curiously.

The Murong Hui who had been sitting on the wooden chair next to him was pretentious. He raised his orchid finger, touched his face, and said with a feminine smile. "My name is Linglong, and I am a doctor at Baitong Pavilion. I heard that Miss Lin knows the long-lost golden needle technique, so I came to visit her."

After she finished speaking, Linglong took off the human skin mask on her face, revealing a pretty face that was three times more charming than a woman's, and gave Lin Zan a coquettish look.

She was even better at acting like a spoiled brat than the courtesan in Baihua Tower, and Lin Zan's eyes widened at the sight, unable to look away for a moment.

Seeing this, Mu Murong Hui frowned and stood directly in front of Lin Zhan, pulling her back to her senses. "What do you want from me?"

"Oh, I came to you because I want some Tiancan powder. Do you have it?" Lin Zan remembered his business and hurriedly said to Murong Hui.

Murong Hui looked calm and continued to ask, "How much do you want?"

"One bottle." Lin Zhan opened his mouth loudly and stretched out a finger.

At this time, Linglong, who was sitting next to her, spoke directly. "Oh, one or two days of silkworms are worth one tael of gold, not to mention the silkworm powder, one tael is worth five taels of gold. Miss Lin asked for a bottle right away, it's really a lion's mouth!"

Listening to his words, Lin Zhan also felt a little embarrassed, then scratched his head and said, "How about half a bottle?"

"I will ask someone to send it to you in three days." Murong Hui didn't say anything, but just glanced at Linglong, and the two left.

When leaving, Linglong came close to Lin Zan, took a closer look at him, and even took the opportunity to touch him.

If Murong Hui, who was standing next to him, had not warned him with her eyes, Lin Zan believed that Linglong would have touched her a few more times before giving up.

"A grown man who acts like a sissy is actually called Linglong. It's true that there are all kinds of things in this world." Lin Zan curled his lips. After finishing this matter, he finally went to sleep peacefully.

Three days later, Murong Hui did not show up, but when Lin Zhan came back from school, there was a small porcelain bottle on the table.

When she opened it, she saw a whole bottle of Tiancan powder inside, which made Lin Zhan very happy. Bixia asked curiously, "Miss, what did you see? Why are you so happy?"

"It's okay, it's okay, Sister Bixia, please take out all the things I prepared in the past two days, they can be used by me." Lin Zan quickly ordered.

Bixia didn't ask anything. After preparing everything, she wisely left and closed the door.

"Everything is ready, only the east wind is missing. Tang Yu, just wait for me." Lin Zan smiled and mixed the things he had prepared with the Tiancan powder he brought.

Looking at the powder in the bottle, Lin Zhan smiled slyly again, and then took advantage of the night to secretly sprinkle all the powder on Tang Yu's silver charcoal.

In the past few days, Tang Yu no longer took the initiative to approach Lin Zan, and even caused her some minor troubles from time to time.

However, Lin Zan adhered to the principle that it is never too late for a gentleman to take revenge, and ignored her.

Just two days after Lin Zhan sprinkled the unknown powder on the silver charcoal, the news that Tang Yu had developed severe frostbite spread throughout Qinglan Courtyard.

"What's going on? I heard that the second young lady of the Tang family kept the house heated every day, so how come she got frostbite?"

"It's so strange. He was fine a few days ago, but suddenly he got frostbite on his hands and feet. I heard he got frostbite on his face, too. It's really scary."

Several young ladies from noble families gathered together in the school, chattering and discussing, and Lin Zhan had a meaningful smile on his face.

"I don't want to become ugly, sister. Please find the best doctor in Beijing to treat my frostbite." At this moment, Tang Yu cried and threw herself into Tang Xiu's arms, begging her to find another doctor for her.

Tang Xiu was surprised to see that her sister also had frostbite on her face. "Don't worry, Yu'er. I will ask the imperial physician in the Imperial Hospital to treat you."

"I heard that after frostbite subsides, scars will be left on the face. Sister, will I become very ugly in the future?" Although Tang Yu is young, he cares a lot about his appearance.

Moreover, because Tang Xiu has outstanding looks, everyone thinks that her younger sister will not be bad either, so they all look forward to Tang Yu's stunning appearance when she grows up.

"No, sister will do her best to cure you." Tang Xiu hugged Tang Yu in her arms to comfort her, but there was a thoughtful expression in her eyes.

After letting out a sigh of relief, Lin Zan was obviously in a good mood. However, when he was leaving school, he saw his master, the dean, coming to Qinglan Courtyard with his senior brother Qin Shang.

At the same time, he also saw Tang Xiu. She was walking in front with the appearance of a fairy. Lin Zhan was stunned for a moment, then he knew that the two of them were here to treat Tang Yu.

I really didn't expect that the Tang family could actually invite the director of the Imperial Medical Bureau. They are indeed powerful and should not be underestimated.
