A strand of silver Spiritual Power appeared at Tang Gu’s fingertips.

Just as he was about to slowly probe into the five layers of the array, Chen Xuan spoke up.

"Elder Tang, there are six arrays in here, which is double the previous amount, interconnected in such a way that any slight mistake will trigger all the arrays."

Tang Gu looked at him somewhat surprised, "How do you know that?"

Even he had to enter from the outside bit by bit and then slowly deduce it.

The likelihood of mistakes in this process was incredibly high.

But the way he spoke just now was so certain, as if he had completely seen through the array.

This...

Chen Xuan suddenly didn’t know how to explain it to him.

"Just listen to me, I’ll sketch the general situation of the six layers of arrays inside for you now."

"Alright!"

Upon hearing this, Tang Gu nodded and did not pursue the matter further.

After all, everyone has their secrets.

Especially experts like them, even more so.

The next moment, Chen Xuan’s eyes glowed with intense blue light, and in an instant, arrays appeared before him.

"What kind of technique is this? To be able to directly see through arrays!"

Tang Gu was shocked.

But if anyone were to be surprised, it was Chen Xuan who was most astonished because the arrays he saw this time were different from the previous ones.

To be precise, it seemed the last two arrays were capable of changing.

"Damn, what the heck is this?"

He retracted his Telepathy immediately and informed Tang Gu of this situation.

"Changes?"

Tang Gu looked at Chen Xuan doubtfully.

"Yeah, I’m sure it’s different from what I saw last time, and the differences are significant!"

There was no way he could be mistaken about this.

"Is that so?"

Tang Gu knew he definitely wouldn’t joke about something like that.

But an array that could change by itself, this... seemed rather impossible!

Suddenly, as if realizing something, he burst into laughter.

"What? Elder Tang, do you understand now?"

"Mm!"

Tang Gu nodded and began to explain to him, "It’s not the arrays that change, but they have several forms."

"Each form corresponds to different times."

"I once saw it in an ancient array manual."

"Array corresponding to the time!"

Chen Xuan murmured, indeed these arrays were incredibly complex.

This point he had to admit to Tang Gu; no wonder he had researched arrays for millennia, even if he was a Dao-ranked, at least when it came to arrays, he was far inferior.

"So, do you have confidence, Elder?"

"Are you overestimating me or looking down on the Dao ranks of Great Yu? Anyone who can set up such arrays are all array masters!"

"Let’s take a look before saying anything else!"

Confidence?

To be honest, he felt uncertain now.

Without knowing how many hours it takes for the forms to change, if the time is long, it’s doable, but if it’s short... then it’s really no hope.

He had this much self-awareness.

"Alright!"

Chen Xuan nodded and then activated Telepathy again.

First, using Spiritual Power, he sketched the general situation of the first four layers of arrays in front of Tang Gu.

"It is quite complex indeed."

Tang Gu’s expression became serious.

Even though Chen Xuan’s sketches were simple, with his keen eyes he could immediately see how complex these arrays were.

He then moved his fingertips, a thread of Spiritual Power slowly penetrating into the outermost layer of the array.

"Hiss... this!"

Tang Gu felt the general situation of the outer layer through Spiritual Power, and his heart was instantly chilled.

It’s more than just complex.

The densely packed runes, at least a hundred thousand.

Moreover, some ancient runes were involved within them.

"This is really challenging for an old man like me."

He chuckled bitterly to himself.

But having already agreed, he had to bite the bullet no matter how difficult.

Until dawn broke, Tang Gu withdrew his Spiritual Power.

Just as he was about to speak, Chen Xuan grabbed his arm, and the two instantly disappeared from the entrance of the Library Pavilion’s fifth floor.

The moment they left.

Ye Jinghong appeared here.

After carefully checking to make sure there were no problems, he left.

Now, early morning patrols of the Library Pavilion’s fifth floor had become a habit for him.

For some reason, he recently began to feel a bit uneasy again.

The last time he had this feeling, Shen Xuan died.

This really frightened him.

Thinking about it, the only thing that could make him uncomfortable was the Library Pavilion of the Three Judicial Departments.

Even though he could perceive everything here, sometimes seeing it with his own eyes made him feel more at ease.

That’s why even though there are constables guarding below the Library Pavilion day and night, he is still willing to check personally.

"You two keep a close watch, there must be no mistakes here!"

At the entrance of the Library Pavilion, Ye Jinghong once again reminded the two individuals in white clothes.

"Yes, Lord Ye!"

The two responded in unison.

However, after he left, the two continued to transmit messages.

"Is Director Ye frightened by the incident where the Library Pavilion was destroyed last time?"

"I think so, now he patrols twice daily!"

"But you can’t blame him, Director Qin died really unjustly."

"Mm!"

In their eyes, Qin Ke was just the scapegoat.

Both Dao Realms from Great Yu died, what could someone in the Profound Realm do?

Meanwhile, Chen Xuan and Tang Gu emerged from a spatial rift, arriving in the main hall.

"What happened?"

"Ye Jinghong just appeared."

Fortunately, he had been monitoring the entire Three Judicial Departments.

The moment Ye Jinghong moved, he knew.

"By the way, Elder Tang, how is it?"

Chen Xuan was most concerned about this matter now.

"A bit troublesome!"

Tang Gu’s expression was very solemn, "Even the outermost layer of the array will take at least a month."

The reinforced array was indeed too complex.
