"It's alright," the Fourth Prince said. "Listen to me, she's always had a problem with you. I don't want you to go see her out of kindness only to be met with her cold words. Listen to me, go back to sleep."

"Alright then," Lanqin said. "Once you arrive, send someone to let me know, whether there's anything to discuss or not."

The Fourth Prince nodded and said, "Yes, I understand."

Fourth Master insisted that he could go by himself and that Lanqin did not need to accompany him. Seeing this, Lanqin did not insist any further and let him go.

When the Fourth Prince arrived at Yikun Palace, the eunuch shouted loudly, "His Majesty has arrived!"

Everyone immediately knelt on the ground and shouted, "Long live the Emperor! Long live the Emperor! Long live the Emperor!"

Upon seeing the Fourth Prince arrive, the imperial physician immediately stepped forward to apologize.

"Your Majesty, please forgive me. I have failed to take good care of the Imperial Concubine," the imperial physician said.

"No need for formalities, please rise," said the Fourth Master.

"Thank you, Your Majesty."

Seeing the imperial physician kowtow and confess his guilt, the Fourth Prince thought that Consort Nian's illness must be unusual this time. He had a bad feeling and hurriedly asked, "Imperial Physician, what's wrong with Consort Nian? Why did she suddenly faint?"

"This, this..." the imperial physician stammered.

"Speak up now!" Fourth Master roared.

"Your Majesty, please calm your anger. I believe that the Imperial Concubine's actions were caused by poisoning."

"Poisoned!" Fourth Master exclaimed in surprise.

He couldn't help but recall the recent incident where many people in the palace had been poisoned, including Hongli himself. The poisoner was becoming increasingly brazen; one day they might even try to poison him. He was determined to find the poisoner this time, no matter what.

"Do you know what kind of poison it is?" Fourth Master asked.

The imperial physician looked troubled and said, "This, Your Majesty, has not yet been able to find out."

"Useless! What use are you to me!" the Fourth Prince cursed.

"Your Majesty, please forgive us." The imperial physicians knelt down again.

"You must find a way to save Consort Nian, or the people in the Imperial Hospital will all be punished." The Fourth Prince was furious. The person who poisoned her was so brazen, and he not only didn't know who it was, but he also couldn't find out what kind of poison it was. How could he not be angry?

Furthermore, if a noble consort were to be poisoned in such an inexplicable way, it would be a great loss of face for the emperor, the Fourth Prince.

The Fourth Prince was too lazy to pay attention to the imperial physicians anymore. He told them to find out the truth as soon as possible. Then the Fourth Prince went to ask the maids who served Lady Nian, namely Cui Ling, Bai Zhi and Lü Ning.

"Tell me everything Consort Nian did today," the Fourth Prince said.

They told the Fourth Prince about Nian's daily life, and after thinking about it carefully, he found nothing unusual.

“Actually, Her Majesty’s health has been poor ever since her two sons died young,” Cui Ling said. Then she knelt on the ground and kowtowed repeatedly, saying, “Your Majesty, please investigate the truth and give our Her Majesty an explanation. Her Majesty has suffered so much. All these years she has been alone in the palace, with no one to talk to.” She wiped away tears as she spoke.

The Fourth Prince said to Cui Ling, "You are indeed a loyal servant. Don't worry, I will not let Consort Nian suffer injustice for nothing."

Then the Fourth Prince asked, "Your Highness, have you been at odds with anyone lately?"

The maids exchanged glances, none daring to speak. Everyone in the palace knew about Consort Nian's temper and personality; she had probably offended everyone in the palace. In the end, everyone was a suspect, but they dared not speak. If you were to ask who the Imperial Concubine hated the most, it would naturally be Consort Xi of Changchun Palace.
