After transmigrating into the book, I helped my mother reconcile with her divorced husband.

The blood exchange process is amazing; you can clearly feel the blood flowing through your body, from your left hand to your right, and from your right hand to your left. The blood exchange is completed just as the carriage stops.

The good news is that the blood transfusion was very successful, and Lu Yun's poison is gone.

The bad news is that the device cannot filter out all the toxins in the blood.

The good news amidst the bad news is that the original owner had a special constitution, having been immersed in medicine since childhood, making her immune to all poisons. Those poisons, deadly to Lu Yun, were actually beneficial to Lu Zhiyuan. The poison entered her heart meridian, numbing her cardiovascular system, and by a twist of fate, helped prolong her life.

When the bad news is within the good news, she will die a particularly painful death.

Lu Zhiyuan didn't care; what she cared about was that Lu Yun wouldn't die and could continue living.

Lu Yun had no idea what had just happened; all she knew was that she was better. Seeing that Lu Zhiyuan's wound was still bleeding, she quickly bandaged it for her, forgetting her own injuries.

"What did Miss do?"

"Blood transfusion!" Lu Zhiyuan leaned weakly against Lu Yun: "Don't worry, it's alright."

"Nothing wrong? You've ruined yourself like this and you're telling me nothing's wrong." Lu Yun didn't know what to say, he just kept bandaging Lu Zhiyuan. The same wound would be expected on him, but on Lu Zhiyuan it was unforgivable.

"Lu Yun's life is worthless, why must you hurt yourself like this, Miss?" Lu Yun looked up: "Does Miss want me to regret it for the rest of my life and never be able to forgive myself?"

“It’s not as serious as you make it out to be.” Lu Zhiyuan used the blade that came with her bracelet to cut two pieces of cloth off Lu Yun’s body and carefully bandaged his wounds. “Your life is very valuable, not to others, but to me. You are my brother, and like Liu Ying, you are my family. I can’t just stand by and watch my brother, my family, get into trouble and do nothing.”

"But a blood transfusion..."

“It’s not what you think.” Lu Zhiyuan sat up. “See these two wounds? They’re shallow and won’t kill you. What I did just now was to draw my blood into your body, to fight poison with poison. As you know, I’ve been taking medicine since I was a child, and I’ve eaten all the best medicines from all over the country. Even the best medicine has some toxicity, and with the accumulation of toxicity, my blood has long become the most poisonous blood in the world.”

"Miss?!"

"Why that look? You've seen poisonous snakes before, right? But have you ever seen a poisonous snake kill itself by poisoning itself?"

"Miss is a human, not a snake!"

"Different species, but the principles are the same. Look at me, do I look like something's wrong?"

Lu Yun stared at her; her complexion was rosy, and she seemed to be in better condition than before the blood transfusion.

“I used earrings instead of silver needles to guide the blood through your body, using poison to fight poison.” Lu Zhiyuan yawned: “It was originally a very dangerous method, with less than a 50% chance of success, but I didn’t expect it to succeed.”

"Miss, you must never do that again!"

Lu Yun didn't understand medicine, but he understood what this less than 50% certainty meant.

"Then you should take good care of yourself and not get hurt again."

Lu Zhiyuan lay down, resting her head on his lap. She felt a little uncomfortable and didn't want Lu Yun to notice, so she pretended to be cold and curled up.

Lu Yun stared at the curtains that were being blown by the wind.

There had been no sound from outside the carriage since then, and the coachman had left; no one knew where he had gone. Looking at the scenery outside, it seemed to be a courtyard, but no one knew who owned it.

After waiting another fifteen minutes, a sudden gust of wind arose outside, followed by rain. The cold wind, carrying raindrops, blew in, and Lu Zhiyuan shivered. Apart from the medicine box and needle kit, everything else in the carriage was there. Lu Yun found a cloak and covered Lu Zhiyuan with it. Seeing that she was still curled up, he hesitated for a moment, then pulled her into his arms.

As darkness fell, Lu Zhiyuan buried her head in Lu Yun's arms, clutching his sleeve.

Lu Yun was somewhat anxious and kept glancing outside.

He wasn't one to sit idly by and wait for death, but he was injured, and the young lady had repeatedly instructed him not to use force until his injuries healed. The young lady herself was also still recovering from an old ailment, and now had new injuries; without absolute certainty, she couldn't act rashly.

What is the Crown Prince doing?

What is Han Ting doing now?

Didn't they realize the young lady was missing?

What about Xie's young apprentice? Didn't he take Liuying back? The apprentice is unreliable; Liuying should at least tell His Highness and Han Ting that something happened at the Liu family's old residence.

There are only two roads leading to the Liu family's old house. If they were any clever, they would have found it by following the tire tracks on the ground.

They waited and waited, until late into the night, when finally there was movement outside the carriage.

In the pouring rain, several people rode up on horseback, the one in the lead wearing a straw hat and dressed in all black.

Upon reaching the carriage, the man leaped down and lifted the curtain completely.

"Is the Crown Princess inside the carriage?"

Lu Yun did not answer, but looked at him warily.

The newcomer removed his straw hat, revealing a face crisscrossed with scars, resembling a ghost.

"I didn't mean to frighten you two!" The newcomer chuckled, his features becoming even more menacing. "My surname is Gu, and my given name is An. If you're investigating that case from back then, you should have heard of me."

"Are you General Gu An, the one who was in charge of escorting grain supplies and disappeared at the Hanging Platform?" Lu Yun sized up Gu An.

He had heard the name Gu An from the young lady, but whether the person before him was real or not was still unknown. Even if he was real, getting involved with those people was no good.

"Was it General Gu who did what happened at the Liu family's old house? What is the relationship between my brother Alu and General Gu? And that groom from earlier, he was originally a member of the Qinghe Gang, but he betrayed his leader and joined you. What is your purpose? To stop us from investigating the case and prevent the truth from being exposed?"

"Shall we talk somewhere else?" Gu An waved, and the person behind him opened an umbrella: "The Crown Princess is frail and it is not suitable for her to stay in the carriage."

"Knowing that Miss is in poor health, General Gu An didn't come earlier." Lu Yun retorted, "In such terrible weather, you left us here for several hours. Did you want to see if we could escape, or did the general want to give us a show of force and let us know how powerful the general is?"

The people behind Gu An tried to make a move, but Gu An suppressed them.

“Young Master, you misunderstand. The Liu family's affairs have nothing to do with us, nor does the person who betrayed the Qinghe Gang by driving the carriage. We merely received advance warning and used a ruse to capture him. During interrogation, we learned that the Crown Princess was in the carriage. My men dared not make a decision and ordered someone to inform me, but even with our haste, we were still too late.” Gu An knelt on the muddy ground: “Your subject Gu An begs Your Highness to punish me!”

Lu Zhiyuan lifted her eyelids slightly: "It's cold, let's talk somewhere else."

Whether it's a dragon's den or a tiger's lair, since we're here, we might as well make the best of it. Regardless of who these people are, the fact that they haven't made a move proves there's something to gain from them. As hostages, what's frightening isn't what the other party wants, but rather that they want nothing more than their lives.

Lu Yun took the umbrella and got out of the car, with Lu Zhiyuan following closely behind.

Her feet had barely touched the ground when her body went limp. Luckily, Lu Yun caught her, preventing her from falling. Looking around, the night was thick, obscuring both the path ahead and the way back. She pointed randomly at someone: "Carry me!"
