In order to save himself, the prince summoned 100,000 dragon riders at the start.

Lu Yuan slapped his forehead.

The fighting was tense the day before yesterday due to a night raid.

They fought from nightfall until dawn.

I completely forgot about signing in!

And yesterday was the same.

The three of them, including Jiang Qianning, fought until dawn.

I forgot about signing in again!

Fortunately, the system has saved the sign-in opportunity.

It's added to today's check-in record.

In other words.

Lu Yuan now has two chances to sign in!

Lu Yuan's tense heart finally relaxed.

If you waste a chance to sign in, you'll lose a lot!

"System, I need to check in!"

Immediately, Lu Yuan reopened the system's sign-in interface.

[Ding! System check-in in progress...]

[Sign-in successful! Congratulations, host, you have obtained the supreme imperial weapon, the Mountain and River Seal!]

[Ding! System check-in in progress...]

[Sign-in successful! Congratulations, host, you have obtained the Heavenly Rank Martial Skill, Prajna Honey Touching Palm!]

"What a pity, there's no reward that directly increases cultivation level."

Looking at the two sign-in rewards given by the system, Lu Yuan was slightly disappointed.

Now, Lu Yuan has everything he needs.

What's lacking is cultivation!

However, the two rewards for this sign-in event are also quite good.

The Mountain and River Seal, being a top-grade imperial weapon, is no weaker than the Emperor-Slaying Spear!

The Mountain and River Seal even has another function: it can absorb the dynasty's fortune!

To be precise, it's not about absorbing, but borrowing.

The Mountain and River Seal can bind an entire dynasty.

The greater the dynasty's fortune, the stronger the power of the Mountain and River Seal!

In the end, it could even rival the Dao Treasure!

As for that Heaven-rank martial skill, there's not much to say.

Firstly, Lu Yuan's skill in obtaining honey is already quite good...

Secondly, he obtained no fewer than four or five high-level immortal-grade martial arts techniques from the man in black robes!

Lu Yuan no longer cares about mere Heaven-rank martial arts techniques!

If it weren't for this martial arts skill, it would have been directly bestowed upon me by the system.

Lu Yuan was too lazy to even learn!

but.

Because this martial art is directly bestowed upon the user, the reward is quite good!

......

After everything was sorted out.

At this time, Xu Chu also sent someone to inform him that he had made a discovery on his side.

then.

After leaving Jiang Qianning, Lu Yuan went straight to Xu Chu!

"Xu Chu, how are things going on your end?"

Where is that man in black robes now?

Upon hearing this, Xu Chu gave a wry smile:

“My lord, I have been interrogating this man in black robes since yesterday!”

"Alas! What a pity..."

Then, Xu Chu briefly explained what had happened to Lu Yuan.

At this point, the man in black robes had been so thoroughly dealt with by Xu Chu that he was almost unrecognizable as human.

Although he only had one last breath left, he only had one last breath left!

Even so, the man in the black robe remained defiant.

Xu Chu used all his strength, but he still couldn't pry it open!

Apart from some unimportant news.

The man in black robes refused to divulge even a single crucial detail!

"Okay, you've done your best!"

"There's a restriction on the black-robed man's soul; there's nothing we can do about it!"

Upon hearing this, Lu Yuan glanced at the black-robed man who was no longer recognizable as human not far away!

I can't believe it.

This man in black robes was actually the commander of the imperial guards of a powerful immortal dynasty in the Upper Realm!

Perhaps it was because he frequently came into contact with the secrets of that immortal dynasty.

The black-robed man's soul had already been placed under a restriction!

If someone forcibly controls or forcibly accesses their memories.

The restriction will immediately self-destruct, turning the man in black robes into a complete idiot!

"By the way, what about that jade slip you mentioned?"

At this moment, Lu Yuan asked Xu Chu again.

Just now.

Xu Chu mentioned the jade slip once, and Lu Yuan remembered this key word!

Upon hearing this, Xu Chu immediately handed Lu Yuan a jade slip and said:

"My lord, this jade slip was found on the man in black robes."

"As for the purpose of this jade slip..."

"I truly do not know!"

Xu Chu said to Lu Yuan with a wry smile.

but.

Since this jade slip was kept close to the black-robed man's body.

This shows that this jade slip is extremely important!

Upon hearing this, Lu Yuan took the jade slip and examined it with curiosity.

Surprisingly, the jade slip had a fluorescent glow and emitted a faint spiritual energy fluctuation.

It exudes many strange things!

but.

This jade slip, like the soul of the man in black robes, is sealed with a seal!

If someone else opens it without authorization, the entire jade slip will turn into a pile of dust!

"How could such a mere jade slip be covered with so many restrictions?"

Lu Yuan looked at the jade slip in his hand and let out a soft exclamation.

This piqued Lu Yuan's curiosity.

What kind of information would be encrypted in such a way?

Lu Yuan examined the jade slip closely under the light.

They discovered that this jade slip appeared to be just an ordinary piece of jade.

It's no different from normal jade!

At this time.

The black-robed man, who was already on the verge of death, revealed a strange smile on his face after seeing Lu Yuan holding the jade slip!

At this time.

Empress You Susu of the Nine Netherworlds seems to have made a discovery.

He let out a soft exclamation!

"Susu, have you discovered something?"

Seeing You Susu's reaction, Lu Yuan casually asked her a question.

A strange light flickered in You Susu's eyes as she said:

“My lord, I am quite familiar with some formations.”

"And this jade slip... seems to contain some kind of formation?"

You Susu said somewhat uncertainly.
