Bi Fang repeatedly thought back on it and could confirm that the pill he had taken yesterday when his consciousness was fuzzy, had a familiar taste!

This type of pill had the effect of suppressing pain. It was the same as the one M had given Bi Fang when he was seriously injured in the warzone!

However, based on what he knew, the formula for this pill was extremely complicated. The production process placed great importance on the heat and the method of mixing it. Only M could grasp the key ingredients to produce it.

Who gave this to Wu Mei?

Does she know M?!

Bi Fang speculated about the relationship between Wu Mei and M and even thought that they were biological sisters.

He raised his hand to block Wu Mei's path, looking like he would not let her go if she did not respond to him!

Wu Mei did not expect Bi Fang to remember something that happened so long ago. She looked at her former disciple with mixed feelings. Recalling his actions of wanting to kill Ben to take revenge for her, she was even more touched and helpless. Afraid that he would pursue the matter, she did not dare to answer casually.

Her eyes darted around as she pondered for a moment. Leaning against the wall, she crossed her arms and looked up at Bi Fang as she said, "I'm M's last disciple."

"M hoped that I could hide my identity and devote myself to studying medicine, so you guys don't know about my existence..." Wu Mei lied perfunctorily. When Bi Fang saw her smile that seemed like she was joking, he did not dare to believe it for a moment.

Narrowing his eyes, he recalled M's style and felt that Wu Mei's words seemed to be somewhat believable.

"What evidence do you have?"

"Did Teacher give you any keepsake? Or... did she say anything to you?"

Bi Fang was a meticulous person. Seeing his shocked and agitated gaze, Wu Mei thought back and said, "When she was on a mission, she was nearly injured and drowned. The villagers nearby saw her floating in the river and brought her home."

"That time, she was on the verge of death. It was the villagers who rescued her using the ancient method of smearing cow dung."

Bi Fang was astonished and covered his mouth with his fist. He was so shocked that he couldn't utter a single sound.

This was M's personal experience. Other than Bi Fang, who had been ordered to find her, no one else knew!

M found it embarrassing and did not mention it to anyone. She even requested Bi Fang to keep it a secret for her!

Wu Mei actually knows?!

"There is a cinnabar mole on the inside of her left arm. As she felt that a special mark would affect her mission when disguising her identity and was afraid that her identity would be exposed, so she underwent surgery to remove this mole..."

As Wu Mei continued speaking, there was no longer any doubt in Bi Fang's eyes. Instead, his eyes were red and he was choking up.

Bi Fang was the one who had personally operated on the mole. It was also a secret matter that no third person knew!

He did not expect Teacher to trust Wu Mei so much that she was willing to tell her about the past and these stories?

"Little Junior Sister! Where have you been previously?"

"Why didn't you tell Senior Brother about your identity?! Senior Brother nearly did something wrong. Can you forgive me?"

The hostility in Bi Fang's eyes disappeared. He wiped his tears adorably and said in a choked voice, "I didn't expect to meet Teacher's last disciple in my life. When did you separate from Teacher?"

Hearing Bi Fang's multiple questions, she listened in amusement to his remorse and yearning for M.

"Let Senior Brother hug you! You've suffered!"

Bi Fang hurriedly opened his arms, wanting to hug Wu Mei.

Just as he was about to hug Wu Mei, Li Nanchen appeared from behind him with a cold expression. He grabbed Bi Fang by the collar and threw him aside.

"Don't hug as you please!"
