Madam Lin remained seated in her wooden wheelchair the entire time, and did not even get up when she saw Su Ruojin.

This only proves one thing: Madam Lin has a problem with her legs.

"Grandmother, what happened to your leg?" Su Ruojin asked.

Madam Lin sighed, "I don't know either. They kidnapped me, and when I woke up, I couldn't move my legs. I could only sit in this wooden wheelchair. They even sent an old woman to take care of my daily life."

Su Ruojin quickly checked Madam Lin's pulse and examined her legs, then breathed a sigh of relief: "Grandmother, it's alright. They just sealed the acupoints on your legs with silver needles. I will definitely be able to unseal them for you after we leave."

Su Ruojin was afraid that her grandmother would worry, so she didn't tell her the whole story. In fact, there was another kind of poison in Madam Lin's body.

This poison won't kill you, but it will weaken your legs, and over time you'll completely lose the ability to walk.

"Grandmother, let me carry you out." Su Ruojin bent down, wanting to carry the old lady Lin on her back.

Jiang Qi'an quickly stepped forward: "I'll take care of it, Madam Lin, please forgive me." He then helped Madam Lin up and carried her on his back.

Su Ruojin didn't argue; given Jiang Qi'an's height of eight feet, he was indeed more suitable than her in this situation.

The three hurriedly left the dark room.

Cuiyun Villa remained quiet, and no one had yet discovered that Zhou Renjiang was in trouble.

After closing the hidden door of the artificial hill, Hu Qing, who was guarding outside, came to meet them. Su Ruojin asked him to rescue the girl, and the group quickly left the villa.

Back at the inn, Su Ruojin gave acupuncture to both Old Madam Lin and the young girl, and then had Yanluo brew medicine for them to drink before she felt at ease.

"Grandmother, what exactly happened back then?" Su Ruojin asked as she entered Madam Lin's room.

Madam Lin recalled, "That day I was thinking of buying you some dried apricots from Yueji. On the way back, I was suddenly knocked unconscious. When I woke up, I found myself in a carriage. I didn't know exactly where we were. When they weren't looking, I threw the dried apricots and an earring out of the carriage, trying to leave a mark for you."

Later, they found I was awake, so they gave me medicine. I don't know how much time passed, but when I woke up I was in this room. I couldn't move my legs. The old woman outside was there to take care of me and also to keep an eye on me.

"Then why is there a herb rack in your room?" Su Ruojin asked, puzzled.

If you really want to imprison someone, just lock them up. Why is there a herb rack in Grandma Guan's room?

"They asked me to concoct an antidote for the Corrupted Heart Pill, but I didn't even know what the Corrupted Heart Pill was, so how could I possibly concoct an antidote? However, I said that I needed to do herbal research first, and I would name a few different herbs each day, and they would send me different herbs."

Although Madam Lin did not know what the other party's purpose was, she knew that stalling for time was the best course of action.

Su Ruojin fell into deep thought after hearing this.

The "Heart-Corroding Pill," as the name suggests, is a pill that, when ingested, causes the heart to rot and lead to death within half a month.

For half a month, the poisoned person had to endure the excruciating pain of their heart being gradually corroded every day, and there is currently no cure.

However, the medicinal materials used to make the Corrupted Heart Pill are rare and hard to find, making one pill is quite expensive.

If you really want to poison someone, it has a similar effect to the Heart-Corroding Pill. There are many low-cost poisons available, so no one bothers to make this one.

Over time, very few people knew about this poison, let alone researched any antidote.

Why would the other party want the grandmother to make an antidote for such an obscure poison?

"Grandmother, did they pressure you to make the antidote immediately?" Su Ruojin asked.

Madam Lin shook her head: "No, they don't seem to be in a hurry. They just send me whatever medicinal herbs I need. The old woman who was watching over me outside even asked me to make Longyang Pills and urged me to make them within two days."

Longyang Dan, as the name suggests, is a medicine needed by men. It is estimated that Zhou Renjiang had his grandmother make it under the guise of official business.

Su Ruojin understood somewhat. It seemed that these people were testing her grandmother's medical skills. Considering the previous rumors that the Regent had gone to Yanyang to find the Sage of Medicine, it was likely that they had mistaken her grandmother for the Sage of Medicine.

"Grandmother, everything is alright now. You should rest well. I'll come to see you again tomorrow."
