After Ji Yunshu’s reminder.

Li Cheng finally realized he had arrested the wrong person!

However, having arrested someone in public like this and now having to release him was rather embarrassing. Moreover, concerned about saving face, he hesitated for a while before reluctantly instructing the two guards who were holding the butcher.

“Release him!”

He waved his hand at the guards holding the butcher.

Telling them to let go.

The two guards looked at each other.

Then slowly released their grip.

Fortunately, this was a false alarm!

The butcher had finally cleared his name.

However, upon gaining his freedom, he shook his hands forcefully. Though angry inside, his face showed grievance as he said, “I already told you I didn’t kill anyone. You officials just love wrongly accusing people.”

Li Cheng glared at him, “You were a suspect. What’s wrong with this official arresting you? Do you have complaints?”

The butcher instantly cowered, “No… no.”

How would he dare?

“This official arrests people based on evidence. Now that it’s proven you’re innocent, naturally you must be released.”

“Yes, yes, yes.”

Ji Yunshu pulled Li Cheng aside and said softly, “Even if Du Mubai truly was struck here, that doesn’t prove the butcher killed him, because there’s no direct evidence proving he killed anyone. Any murder case must have sound reasoning and evidence. Next time before Young Master Cheng arrests someone, you must consider these things. Otherwise, if you don’t care about your official dignity, don’t you at least care about public opinion?”

She was reminding him.

Li Cheng understood and said, “I understand.”

“I hope Young Master Cheng truly understands.”

This fellow could forget things in the blink of an eye.

That’s why Ji Yunshu reminded him so.

Li Cheng said, “I truly understand now, rest assured.”

Ji Yunshu didn’t want to say anything more.

A guard came over and asked, “Lord Li, what do we do now?”

What to do?

Li Cheng shot him a glance, “Of course we hurry to the next location.”

“Yes, yes, yes.”

“Lead the way quickly.”

“Yes!” The guard bowed and quickly responded, moving forward to direct everyone to the next location.

Li Cheng said to Ji Yunshu with a smile, “Young Master Ji, it’s still early. Let’s hurry to the next location.”

“Mm.”

She nodded.

Thus, the group immediately went to another place.

The second location was on a street.

The street wasn’t particularly remote, but it was wide.

Pedestrians and carriages passed along the road.

Not crowded, but not deserted either.

“Make way, make way.” Li Cheng’s guards began shouting from a distance.

Blocking the pedestrians on the road.

Then they cordoned off a certain area.

This naturally drew the common people’s displeasure.

“What’s going on?”

“I don’t know! How would we common folk know so much about what the authorities are doing?”

“I heard they’re investigating a murder case.”

“Whose murder case?”

“The two cases causing the biggest uproar recently.”

With this explanation, everyone understood.

However—

Someone else asked, “Why is the murder investigation here now?”

No one knew.

So everyone gathered around the perimeter, waiting, watching, listening.

The guard who was leading the way pointed at the ground and said to Li Cheng, “Sir, it’s right here.”

Li Cheng, Ji Yunshu, and Jingrong walked over.

On the ground before them was a row of protruding small circles.

Also made of cement.

Just like the small mounds the butcher had used to hang pork earlier.

These small mounds were arranged in a row on the ground, specifically installed to cushion the impact force of carriages.

Just like modern speed bumps!

This was Ji Yunshu’s first time seeing such a thing!

She hadn’t expected ancient people to have thought of this so early.

So she said, “How interesting.”

Interesting?

Jingrong was standing beside her and suddenly heard her mutter this.

He leaned closer and asked, “Interesting? Why interesting?”

Curious baby.

Ji Yunshu pointed at the small mounds on the ground.

She said, “These are very interesting.”

“What’s interesting about them?”

“…This…” Ji Yunshu didn’t know how to explain, so she squeezed out two words, “They look good!”

Look good!

What kind of logic was this?

Jingrong seemed to understand yet not understand.

What was so good-looking about these mounds?

Before he could ask—

The guard beside them said, “Sir, look, it must be here. Du Mubai must have fallen here!”

Absolutely certain.

After hearing this, Li Cheng also nodded, stroking his chin, and said, “Mm, it does seem like it!”

The people around were silent.

He continued, “Du Mubai was probably pushed down by the murderer here, then his whole body fell, landing on his back, and struck here. That should… probably be the logic.”

But he wasn’t quite certain, so after speaking he looked at Ji Yunshu again, waiting for her to speak.

Ji Yunshu and Jingrong exchanged glances.

Then the two of them focused their gaze on the mounds on the ground!

Ji Yunshu thought, is this the place?

It doesn’t seem like it!

Her brow furrowed slightly involuntarily.

Li Cheng observed her expression, unable to understand.

When he saw her expression become increasingly grave, Li Cheng finally couldn’t help but ask, “It’s not here?”

Ji Yunshu’s eyes suddenly sharpened, and she said, “It’s absolutely not here.”

She used the word “absolutely”!

“Why?”

The surrounding people also looked over, straining their ears to listen.

Wanting to know the reason.

Ji Yunshu also explained with full patience, “In this type of situation, there are usually two scenarios. One is when a person falls while still conscious. In that process, the body will definitely react, such as struggling. However, once a person struggles, every joint in the body will also react accordingly, so the point of impact when falling will be different! This would cause the point of impact on the back to also be different. If it’s different, then the force of impact will vary, and the protrusions on the back ribs will be different. But the three protrusions on Du Mubai’s ribs are clearly identical, so this scenario is ruled out.”

She explained very carefully, worried others wouldn’t understand, so her speech slowed considerably.

Everyone indeed understood.

Li Cheng asked again, “Then what about the other scenario?”

Ji Yunshu walked around the small mounds on the ground and continued explaining, “The other scenario is… Du Mubai fell after being knocked unconscious.”

“Then what would happen?”

“If he fell after being knocked unconscious, his body would be limp, his joints wouldn’t react, and the points of impact on his back ribs would be different! Those three protrusions absolutely couldn’t appear simultaneously on one rib, so this scenario is also ruled out.”

Both scenarios were directly negated!

The surrounding common people suddenly understood.

They were also hearing such in-depth analysis for the first time.

They all developed admiration for that young scholar.

Master Ji, whom the City Bureau had invited to solve the case, was truly extraordinary.

At that moment, Li Cheng also instantly understood, “So what you mean is… Du Mubai never came here, and the place where his back was struck isn’t here either.”

“Exactly!”
