I bought a secret manual of the Hehuan Sect for ten yuan.

Zhuang Yan was a little frustrated. He had mentioned to his superiors many times that Yu Xiangmin's matter was not so simple.

If we don't take this seriously, we may very well repeat the same mistakes!

However, the higher-ups only sent Fan Linsen with an incomplete Fifth Special Operations Team to provide reinforcements.

It's no use saying anything now. If we're really outmatched, we have to hold out for at least ten minutes!

Fortunately, Yunqiju is located in a special position, built against the mountain, which reduces the pressure of defense.

What puzzled Zhuang Yan was how those people outside could act in such a coordinated manner. Could they be a group of people?

If that were the case, he wouldn't be so worried.

What Xuan'an Bureau fears is not a large number of people, but top-notch experts.

Regardless of the forces behind these people, their strength is limited, and it's impossible for them to send so many people, all of whom are top experts.

Even if such a force existed, it's unlikely they would do something so heinous.

They've already become so powerful, so why make such a fuss over a mere Sun Shizheng or a single formula?

What Zhuang Yan feared most was that these people came from different forces. If they dared to target Sun Shizheng under these circumstances, they must have sent out their elite troops!

After all, the number of people is limited, and they can't hold out against so many people, most of whom are top experts.

"A report indicates that the scoundrels have entered firing range!"

"Three teams report: the rats have entered firing range!"

"Second team report: The scoundrels have..."

Hearing the voice through his earpiece, Zhuang Yan's gaze turned icy. "Kill them!"

"Victory is certain!"

Zhuang Yan's voice rang in the earpieces of all the team members, and in an instant, gunfire erupted from three sides of Yunqiju.

The enemy was well-prepared, and the number of enemies who fell in the first round of shooting was far less than Zhuang Yan had expected. Moreover, they had already figured out the weaknesses of the Xuan'an Bureau.

The experts at the Heavenly Realm level moved nimbly, quickly closing in on the people from the Xuan'an Bureau.

Comparatively speaking, the people from Xuan'an Bureau are not so good at close combat, and the situation is developing in a bad direction.

After the gunshots rang out, members of the Xuan'an Bureau rushed out from the villas located in three different directions from Yunxi Residence, quickly joining the battle.

In just a few dozen breaths, countless people were killed or wounded on both sides!

The battle intensified, and Xuan'an Bureau was outnumbered and faced heavy casualties from its opponents, who were all highly skilled.

However, the enemy underestimated the Xuan'an Bureau. From now on, as long as they are approached by experts, the people of the Xuan'an Bureau will be helpless.

They hadn't expected the Xuan'an Bureau members to cooperate so well, reacting quickly and supporting each other even in close combat. With the addition of snipers providing long-range assistance, quite a few of the enemy's Heavenly Realm experts died in close combat!

"Consolidate your scattered forces and retreat to a smaller formation to confront the enemy!"

"Command team, follow me into battle!"

Zhuang Yan gave the order again and then drew his sidearm.

He knew in his heart that this might be his final instruction.

All that's left is to fight to the death. Everyone knows what to do, so there's not much room for command anymore.

There are fewer and fewer people.

Inside the basement of Yunqi Residence.

Listening to the screams of his comrades before they fell in his earpiece, Fan Linsen could roughly guess the situation outside, and his expression became solemn.

"Almost there, just hang in there a little longer..."

He looked at the time and muttered to himself.

Seeing his expression, Zheng Qiuyi couldn't help but ask, "Is the situation outside not good?"

"Are there reinforcements coming? How long will it take them to arrive?"

Fan Linsen said, "Based on the time, it'll take at most five minutes. Just hold on for another five minutes!"

"Why is it taking so long?" Zheng Qiuyi asked, puzzled. "For a situation of this magnitude, police should be able to arrive at the scene within five minutes in the city. How much time has passed already? Why is it still five minutes?"

"Even if Yunxi Residence is located in a slightly remote area, it shouldn't take that long, right?"

"Didn't you call for reinforcements immediately when the first wave of enemies appeared?"

Fan Linsen smiled wryly, "If we ask the Shadow Martial Arts Hall or the police station for help, they can send the nearest person over in no time."

"But their arrival is pointless; this isn't something that can be solved by just a few reinforcements."

"Reinforcements must come from the Xuan'an Bureau headquarters!"

"From receiving the reinforcement request to mobilizing troops and then to the arrival of the reinforcements, it will take at least twenty minutes!"

"Even deploying helicopters wouldn't be much faster. We can't just use heavy weapons to lock onto Cloud Dwelling and launch an indiscriminate attack, can we?"

Le Fei said leisurely, "You never intended to ask Shadow Martial Hall for help, did you?"

"Are you too embarrassed to ask others for help with your problems?"

Fan Linsen was taken aback for a moment, "You're quite clever, girl!"

"I admit that we did have such thoughts in the past. The Xuan'an Bureau and the Shadow Martial Hall have always been secretly competing with each other, and neither of them is willing to admit defeat."

"After the Xuan'an Bureau took over Professor Yu Xiangmin's safety, the Shadow Martial Hall withdrew..."

"But you've really wronged us this time. We contacted Shadow Martial Hall tonight, but it seems they've run into trouble too."

Zheng Qiuyi continued, "Something did happen. Qin Ge went out after receiving a call from Yingwu Hall. I was just about to contact him to ask what was going on when I found that the signal here was blocked."

"We haven't been able to contact him yet, and we don't know what's going on."

"What a coincidence, he had only been gone a short while before this happened!"

"I told you it might be a diversionary tactic, but he insisted that with people from your Xuan'an Bureau around, nothing would happen. Tell me honestly, what's the situation outside? Are you confident you can handle it?"

"Whether it's a coincidence or not is hard to say!" Fan Linsen narrowed his eyes slightly. "Perhaps those people only dared to make a move because he wasn't around."

"The situation outside..."

"All I can say is that we've done our best, but you need to be prepared that the outcome might be worse."

"Mr. Sun Shizheng".

He looked at Sun Shizheng seriously and solemnly, "There's something I need to say now, which may be presumptuous, but it's also what the higher-ups want."

"Do you have a backup of your research findings?"

"If not, I hope you will consider this now, as my equipment can transmit the information."

"We are all very sorry about what happened to Professor Yu, and we hope that such a tragedy will not be repeated."

"The people of Xuan'an Bureau are willing to die in the line of duty, but the situation outside is indeed not optimistic. I can only say that we have no choice but to fight to the death now, and no one can say for sure what the outcome will be."

"Your and Professor Yu's research results can benefit hundreds of millions of people. It would be a great pity if such results were buried again due to the incompetence of the Xuan'an Bureau."

Do you understand what I mean?

His words made the atmosphere in the entire basement room heavy; they were indeed presumptuous, but also very realistic.

That's a highly effective medicine that can cure cancer. If Sun Shizheng were to die because of the Xuan'an Bureau's inadequate protection and the inheritance could not be passed down, it would be a huge regret, and a regret for the whole world!

This kind of thing has already happened to Xiang Min once. If it happens again, the Xuan'an Bureau should just be disbanded and its staff abolished, and everyone should just go raise pigs!
