Li Yu leaped off the firebird and looked down into the depths of the ravine.

He didn't necessarily have to completely eradicate this Changsheng Sect stronghold.

However, the movable "star railgun" mentioned in the investigation by the three Black brothers did indeed pique his interest.

If we could acquire this powerful strategic weapon and install it in Kangcheng…

Doesn't that mean that Kangcheng has instantly gained a trump card that can deter any hostile forces?

Once the idea came to mind, Li Yu thought about it more and more and it seemed feasible. He was even eager to find and "move" the movable star railgun back to Kangcheng immediately.

Moreover, if he takes the opportunity to completely destroy this Changshengmen stronghold, he might be able to use it as a "gift" to ask Monk Jingshi to help him improve the strength of the underground ghosts in Kangcheng, or even return to the surface.

Given the abilities of the monk Jingshi, he must have a solution.

Although Monk Jingshi didn't say it, Li Yu could still sense his deep hostility towards the Changsheng Sect.

If you make such a request, the other party will definitely not refuse.

Li Yu even felt that if he informed Monk Jingshi now that an important stronghold of the Longevity Sect had been discovered here, the other party would likely come immediately without hesitation and raze the place to the ground, completely destroying it.

The three Hei brothers, who were standing nearby, fell silent when they heard Li Yu tell them to go first.

The two younger brothers' faces were filled with struggle and indecision, and in the end, they both turned their gaze to their eldest brother, Hei Yi, who was the backbone of the family.

Hei Yi's expression was solemn, his brows furrowed, and he was deep in thought.

He was well aware of the enormous risks the three of them would face if the investigation continued.

That also means that they have completely stood on the opposite side of the Changsheng Sect and the forces behind it. Once the news gets out, the three of them will be doomed, and it may even implicate the Hei family.

But is it really safe to leave now?

The secret Zhao Jianan shouted before he died was like a time bomb strapped to them.

Afterwards, when the Changsheng Sect and the forces behind it began to investigate, could these three "survivors" and "insiders" really escape unscathed?

If the authorities were to investigate and hold them accountable in order to cover up the scandal, they would certainly not let them off the hook and could be inexplicably 'sacrificed' at any time.

Rather than being caught in a dilemma, with no way out but a dead end, why not take a gamble!

They're betting that Li Yu can lead them to 'win' and find a way out of their desperate situation!

A bold and meticulous plan quickly took shape in Black One's mind—

Instead of passively and anxiously waiting for what might happen next, it's better to actively cooperate with Li Yu now to completely destroy the Changshengmen stronghold hidden here, and then successfully destroy that star orbit cannon!

Then, when they returned to Thunder Bureau to report, they gave the same story:

All they need to do is claim that they were carrying out an investigation as planned when they unexpectedly encountered Lord Li Yucheng, who was acting alone.

Lord Li Yucheng "temporarily requisitioned" them to cooperate with the operation.

Throughout the entire process, the three of them were only responsible for leading the way and providing limited intelligence support. All the core and critical decisions, including destroying the orbital cannon, were made independently by City Lord Li Yu!

They were merely assisting; it was Li Yu who destroyed the Star Orbit Cannon, eliminating the security threat hidden in Zhongzhou.

In this way, they would not have to bear the retaliation caused by the destruction of the Changshengmen stronghold, nor would they offend the relevant personnel of Tian Shu and the military, and would not arouse any suspicion from above.

After Li Yu completed his mission, he returned to report back to the leaders of the Thunder Bureau.

More importantly, in this process, they perfectly positioned themselves as "innocent support personnel temporarily requisitioned by heroes".

All the real "credit" and the accompanying "focus" and "risk" were placed on Li Yu alone.

The three brothers were thus extricated from this terrifying vortex to the greatest extent possible!

Even if the people behind the Changsheng Sect are furious, they will only focus on Li Yu. The three brothers are just insignificant characters who will not be taken seriously and will become insignificant!

Thinking of this, Hei Yi looked at Li Yu with a hint of "guilt," a resolute glint in his eyes, clearly determined to cooperate with Li Yu.

His gaze hardened, and he first turned to his two younger brothers, lowering his voice and speaking rapidly and clearly:

"Black Two, Black Three, listen up!"

"From now on, all actions will be subject to the orders of City Lord Li Yu, and he will be in charge. Do you understand?"

Hei Er suddenly snapped out of his daze and instantly understood his elder brother's deeper intentions. He also knew that taking a chance in the cracks might actually give him a way out. A look of understanding and agreement flashed in his eyes as he nodded emphatically.

However, Hei San, being the straightforward one he was, completely misunderstood. Hearing his eldest brother decide to stay and cooperate, and seeing his second brother nod, his blood boiled, replaced by a ruthless and excited determination. He slapped his chest and growled:

"Alright! We'll do as Big Brother says! Damn it, today we'll follow Boss Li Yu and fight the Changsheng Sect. If we do, our lives will be worth it!"

Upon hearing this, Hei Yi's lips twitched slightly, and a deep sense of helplessness welled up in his heart. However, there was no time to explain in detail now. He could only hope that his silly little brother would not show up at the crucial moment or let him down.

After settling his younger brother, Hei Yi turned to Li Yu, his face adopting a solemn expression of deep thought and a willingness to sacrifice himself for his friend. He said in a deep voice:

"Lord Li Yu, the three of us brothers have discussed it."

"As investigators from Thunder Bureau, it is our duty to uncover the truth and complete our mission. We have decided to stay and continue to cooperate with your operations until the hidden orbital cannon threat here is completely eliminated!"

"We will do our best to cooperate and follow your instructions throughout the process."

Seeing this, Li Yu simply nodded in agreement without saying anything more.

He didn't care about the three brothers' ulterior motives; let them follow if they want. After all, Hei San's connection with him was indeed different—he truly regarded him as a hero and idol...

As long as they don't cause me any trouble later, that's enough.

After the three brothers reached a consensus, Li Yu did not delay any longer and signaled the phoenix to stay at the edge of the ravine so that it could provide assistance if necessary.

Then, he took the three Hei brothers and prepared to go in and investigate.

As they descended deeper, they discovered that there was indeed a hidden world beneath the ravine.

The people of Changshengmen cleverly utilized the complex natural terrain and rock formations here, not only perfectly concealing the entrance to their stronghold, but also carving out a sizable space in the ravines and crevices to establish a fully functional settlement.

Even without space to hide, they can use the flowing water in the ditch for perfect cover.

Li Yu and the others concealed their presence and slowly approached using the rocks as cover.
