I meet all the requirements for becoming a god in this world!

Looking at Ling Ziyun's bewildered expression.

Cheng Laiyun pondered for a moment before explaining:

"The human body is like a city, and blood flows like soldiers. Each city's soldiers have unique military tokens and codes. If soldiers from other cities are rashly transferred in, the garrison will check their codes."

"If the code matches, they are allies and can pass without hindrance, which means the blood transfusion was successful. If the code does not match, they are enemy forces, and a fight will break out on the spot, resulting in mutual destruction and the collapse of the city."

"Since your medical sect possesses this technique of altering one's own blood into the blood of an injured person, you must have conducted research on blood-related matters, right?"

Hearing Cheng Laiyun's words.

Ling Ziyun fell into deep thought.

After a long silence, he finally nodded and spoke:

"This blood-shaping technique was created by one of the founders of our medical school a thousand years ago."

"Before this, that patriarch had already considered using other people's blood to transfuse into the bodies of the wounded, but the success rate was ridiculously low..."

"Therefore, the Blood Shaping Technique was created, which alters the essence of blood. However, this technique consumes a great deal of energy, and we medical practitioners cannot use it lightly."

"If what you call 'blood type' is true, then wouldn't it mean that blood transfusions can be performed without any magical techniques?"

Ling Ziyun's gaze towards Cheng Laiyun was intense:

"Who told you this? Is there a complete lineage?"

"Hmm... I overheard someone mention it by chance before... As for inheritance, I only vaguely remember some of the methods..."

Cheng Laiyun gave a vague explanation.

"What method?" Ling Ziyun pressed closer, his gaze intense.

"This... let me think about it carefully, and I'll write it down for you later." Cheng Laiyun's eyes showed some helplessness.

"Uh... okay!" Seeing Cheng Laiyun's expression, Ling Ziyun knew he had been a bit presumptuous. He coughed and said nothing more, simply keeping the matter in mind.

Ling Ziyun seemed to remember something, and pointed to Qi Xinxiang, who was still unconscious on the bed:

"By the way, it's the dead of winter now, and the injured person shouldn't catch a cold. Light a fire in the stove and cover the injured person with several more blankets."

"Oh, okay." Upon hearing this, Qi Dazhuang got up and walked towards the next room.

Before long, they brought over three pairs of blankets and carefully covered Qi Xinxiang with them.

As soon as the lid was closed, I heard a soft "thump."

Cheng Laiyun looked over instinctively and saw something wrapped in a gauze scarf fall to the ground through the gap in the quilt.

Without thinking much, he casually picked up the wrapped scarf and unfolded it.

After opening the gauze scarf, they discovered that it contained a jade pendant.

The flowing patterns on the jade pendant clearly indicate that it is a precious object.

One side is engraved with the character "令".

One side is engraved with the character "明" (Ming).

Then look at the unfolded scarf in your hand; it has embroidery on it.

The embroidery is exquisite.

The pattern is also very clear.

In the embroidery, there is a man wearing an indigo long robe, and every fold of the robe is exceptionally clear.

His profile was hidden in the twilight, the curve of his nose changing from light gold to sandalwood brown, and his hair bun, embroidered with tens of thousands of "Shi Mao needles," shimmered with a soft glow in the afterglow of the setting sun.

The man had a jade pendant hanging from his waist, which was exactly the same as the one Cheng Laiyun was now holding.

The woman leaning against the man's shoulder smiled faintly, her eyelashes casting a pale blue shadow on her jade-colored cheeks.

At the point where their sleeves overlap, from the front it appears as if the man is gently holding the woman's fingertips, but from the back it appears as if the woman is placing a red bean into the man's palm.

The edges of the embroidery are decorated with a striking cloud pattern.

From a certain angle, the cloud patterns faintly formed a poem:

"A thread of the heart is secretly threaded like a golden needle."

"Fragrant Soul Quietly Condenses into Colorful Threads"

"The agreement is silently hidden beneath the embroidered background."

"The Ming Dynasty's mountains and seas bear witness to profound gratitude"

The embroidery was so skillful that Cheng Laiyun recognized at a glance that the girl in the embroidery was none other than Qi Xinxiang, who was now lying in bed.

And that man...

Cheng Laiyun murmured the poem softly:

"Heart's fragrance, Lingming... This is an acrostic poem..."

He frowned.

This jade pendant clearly belongs to the man in the embroidery.

It suddenly occurred to me that this jade pendant was a token exchanged between a man and a woman after they had pledged their lives to each other.

Sister Xinxiang... has she secretly pledged her life to someone?

Thinking of this, Cheng Laiyun looked dazed. He looked up at Qi Dazhuang and said:

"Dazhuang, do you know a man named 'Lingming'?"

Qi Dazhuang's simple face froze for a moment, then he finally said:

"The eldest son of the Tian family who is engaged to my sister is named Tian Lingming."

"Is that so..." Cheng Laiyun murmured softly after receiving Qi Dazhuang's reply.

……

……

Qi Xinxiang's condition has stabilized.

Qi Dazhuang was still worried and sat by the bedside to keep watch.

Ling Ziyun rested in her guest room.

In the courtyard, Cheng Laiyun sat alone on a stone bench.

His gaze was deep, fixed on the horizon.

Right now, his mind is filled with thoughts about the Tian family, Xinxiang, and Tian Lingming.

"The Tian family has made it clear that they are breaking off the engagement."

"But judging from the embroidery and the tokens, Qi Xinxiang and Tian Lingming have long had feelings for each other, and it wasn't something that happened in a short time."

"Since Tian Lingming and Sister Xinxiang have feelings for each other, the Tian family must know that Sister Xinxiang is innocent, so there is no need to break off the engagement."

"Unless the Tian family... has some deeper reason."

"What could it be...?"

Cut constantly, the rationale is still chaotic.

All my thoughts seemed blocked, and I didn't know where to begin.

"Come on, let's go." Qi Dazhuang came out of the house at some point. He was a big man, but he looked a little awkward.

Cheng Laiyun snapped out of his daze, his gaze falling on Qi Dazhuang, puzzled:

"What's wrong?"

"Ahem." Qi Dazhuang said cautiously:

"It's my turn to guard the Martial Arts Academy today, and there's another batch of spirit rice coming tomorrow, to the same old place, so we have to escort it back."

"But I have to take care of my sister and can't leave for the time being. Could you stay with me for one night? I can get there first thing tomorrow morning."

Cheng Laiyun's lips twitched, and he rolled his eyes, saying:

"So what if you don't go on duty? After such a big incident, just go back and explain it to Master Huo."

"How could he not understand you?"

Qi Dazhuang opened his mouth, still shaken, and said, "Last time Tao Qian deserted his post, my master beat him half to death..."

"Alright, don't worry about it." Cheng Laiyun was somewhat speechless.

This was the first time he had ever seen someone so obviously afraid of their parents.

"You're such a grown man, and besides, the Martial Arts Academy has a gatekeeper... do you think you can just let a thief in?" Cheng Laiyun grumbled.

"Huh?" Qi Dazhuang was stunned.

"Where is the gatekeeper at the Martial Arts Academy?"

"No?" Cheng Laiyun was stunned.

He had been in the Martial Arts Academy for less than half a month and had never paid attention to this issue.

"No, that's not true." Qi Dazhuang looked at Cheng Laiyun strangely. "The Martial Arts Academy has always been staffed by us martial arts masters on a rotating basis. It's just that you haven't been here long, so we haven't reassigned you to a different post yet."

"Okay, it's fine if you don't have it. Don't worry, it'll be alright."

Cheng Laiyun patted Qi Dazhuang on the shoulder and offered a word of comfort.

Just the next moment.

A sudden inspiration struck him.

His face, which was in the middle of speaking, suddenly froze.

"Whoosh!"

Cheng Laiyun suddenly stood up from the stone bench, his eyes like iron clamps, staring intently at Qi Dazhuang, and asked, word by word:

"The Martial Arts Academy has no gatekeeper?!"
