For a period, Liu Jin had been learning novel medical techniques from Chu Qianli.
While he understood blood transfusions and poison removal, it was Chu Qianli who taught him how to test blood compatibility.
Chu Qianli had said that after testing, the chances of blood incompatibility could be largely ruled out.
This prevented most situations where blood rejection could worsen a patient's condition.
Blood transfusions were rarely used in their era, and each instance was handled with extreme caution, as lives were often at stake.
"Your Majesty, your blood..."
After conducting several tests, Liu Jin cautiously reported his findings: "Your blood... is the most suitable."
"Then use mine!"
Xiao Shunzi wanted to protest, but Chu Jiangnan glared at him. "If it weren't for Li'er, I might not have survived until now. Now that Li'er is in trouble, how can I stand by and do nothing?"
"But, Your Majesty, your health..."
"I will proceed with caution and in moderation. When Prince Ling returns, please summon him. I also wish to test his blood."
"Why Prince Ling?" Feng Yexuan was somewhat annoyed. Why wasn't his blood the optimal choice?
"Miss Chu once said that blood between brothers has a greater chance of compatibility."
Liu Jin, with no time for further explanation, bowed to Chu Jiangnan. "Your Majesty, please!"
"Good!"
The two entered the inner chamber.
Outside, Yang Xun arrived. "Your subordinate requests an audience with His Majesty."
Xiao Shunzi immediately went out and returned shortly, in a hurry. "Your Highness, Prince Ling and the others have returned."
"Quickly summon Prince Ling!"
...Prince Ling's blood was indeed also suitable.
That night, Liu Jin worked tirelessly to treat Chu Qianli.
As dawn approached, everyone finally heard Liu Jin's words: "Her condition has stabilized."
Chu Jiangnan breathed a sigh of relief, feeling somewhat drained. Xiao Shunzi quickly helped him inside to rest.
Chu Lingyang, still stained with blood, was also persuaded by Liu Jin to return to his residence to rest.
Only after Liu Jin repeatedly assured them that Miss Chu would recover did Feng Yexuan agree to leave and meet Leng Ji, who had been waiting for a long time.
"What is it?" If there was no important matter, he would likely kick Leng Ji away for requesting an audience.
Leng Ji could tell that His Highness did not want to leave Miss Chu's room at all.
However, this matter... was somewhat important.
He said in a low voice, "Your Highness, Miss Feng refused to leave the carriage and became a target for assassins. She..."
"What about her?" Feng Yexuan's head began to ache again.
He realized that he had completely forgotten about Feng Ling throughout the entire night!
Yet, his emotions at this moment were complex.
Seeing the woman he cared about poisoned, he wished he were the one poisoned instead.
But Feng Ling... why was Feng Ling the one who occupied his thoughts?
This feeling was clearly contradictory!
"Leng Ji," he suddenly called out.
Leng Ji felt a chill run down his spine. His Highness rarely called him so formally. Could it be that he was going to blame him for insufficient protection?
"Who was the woman I liked before?"
This question caused Leng Ji to fall silent for a good while.
Afterward, he hesitantly replied, "She and Miss Chu once loved and fought each other, shared life and death, vowed never to see each other again due to deep misunderstandings, and also reconciled through hardship, proving true affection."
"There were grievances and grudges, as well as deep affection. When things were good, he would die for her; when things were bad, he once hated her to the bone..."
Leng Ji looked at Feng Yexuan. This question was something even he could not figure out.
"The last time you met Miss Chu, she and Prince He joined forces to injure you. Afterward, Your Highness fell gravely ill and remained unconscious for many days. Upon waking, you never mentioned Miss Chu again."
