"You're saying the Imperial Historian family also controls a secret passage that can transport alien races into the city?"

After reading the information An Xiaoyu gave him, Jiang Yuan became serious. He took out the recording stone he had made and said, "Take a look!"

The recording stone was activated, and the conversation inside was heard by the two of them word for word. An Xiaoyu listened to it twice before putting the recording stone back in Jiang Yuan's hand.

"If that's the case, the Zhao family must also have a secret passage, otherwise they wouldn't have been able to bypass the city's defense system and bring the Holy Spirit Clan into the East City!" An Xiaoyu said with a solemn expression.

Jiang Yuan stopped being frivolous and instead pondered seriously, "I'm wondering now, what kind of secret passage could bypass the city's defense system?"

"Don't forget, there is a super divine vein beneath the East City. The powerful energy field will shield all the nearby formations. If we're talking about the most likely location for the secret passage, it must be along the super divine vein."

An Xiaoyu shared her analysis, clearly indicating that she had done a lot of preparation for this task.

"We only know they have a secret passage, but we can't pinpoint its location. What should we do?" Jiang Yuan couldn't make an effective decision. With his and An Xiaoyu's abilities, they might succeed in stopping one family, but they would inevitably fail in stopping two families at the same time.

"Let's upload the intelligence first and see if Tianfu will send reinforcements!" An Xiaoyu suggested.

Jiang Yuan shook his head helplessly. He opened his access permissions and saw a highly secretive official document on the military network. He opened it and read aloud: "Alien invasions have occurred simultaneously in twelve cities of Zhongzhou. A large number of troops are now being deployed in Ancheng, Luocheng, and Shacheng, the three most severely affected areas by the alien invasions, to ensure an emergency combat readiness state for the twelve cities in the event of war."

Jiang Yuan turned off the AI ​​and shrugged, saying, "It's obvious that Dongcheng is not a key safe zone that Tianfu is focusing on. Moreover, the Holy Spirit Clan will start entering the city tomorrow night. Right now, we can only mobilize troops from the three cities. Not only will this alert them and disrupt the deployment of the three cities, but it's also a question of whether we can get there in time. After all, the distance between Zhongzhou and the three cities is not short, and the transfer of a large number of troops can only be done by warships and on foot."

Teleportation arrays have limitations. Military operations typically involve thousands of people, making it impractical to use teleportation arrays.

“That’s right. What if the Holy Spirit pulls a trap and we have to move our troops here for no reason? The main forces of the other three cities will definitely be unable to resist the invasion of the alien race.” An Xiaoyu nodded in agreement with Jiang Yuan’s statement. The information they had was valid, but they didn’t even know where the enemy’s secret passage was, nor did they understand the specific situation of the Taishi family. It was indeed inappropriate to report now.

"Here's what we'll do. You have a wide network of connections, so first mobilize some trustworthy people in Dongcheng. Then we'll apply to the military for a special operations team at the Divine Realm level. Quality over quantity is key in warfare. With a Divine Realm team plus the local forces in Dongcheng, I think we'll have a significant advantage if we take the initiative!" Jiang Yuan said.

"So what should we do now?" An Xiaoyu habitually relied on Jiang Yuan.

“We haven’t investigated the Imperial Historian’s family yet, right? This timing should be perfect. Let’s first determine the location of the Holy Spirit.” Jiang Yuan was quite skilled at sensing the Holy Spirit.

"No need to confirm, they're upstairs!"

An Xiaoyu pointed mysteriously to the rooftop and continued, "Before I came here, I sounded out the receptionist, and she said that only the top floor is not open to the public. Later, I checked at the stairwell, and it's true. The 108th floor is off-limits to the public, and it's covered with array patterns, so even a mosquito can't fly in."

"The array pattern is simple; I can handle it." Jiang Yuan didn't mind revealing a bit of his trump card; a Heavenly Spirit-level array master was no joke.

“No, the array patterns here are all part of a whole. If even a part of them is broken, it will be discovered!” An Xiaoyu retorted.

“But I discovered that the top level is only open to one hotel supervisor and one cleaner, but there’s a condition: they must be ordinary people, meaning they have no cultivation. Otherwise, any leakage of energy will activate the formation and be discovered,” An Xiaoyu said helplessly.

"Hotel supervisor and cleaner?" Jiang Yuan pondered for a moment, then said with concern, "Going in with these identities shouldn't be a problem, but isn't it a bit too risky to do it without any cultivation?"

“I have two pills that can suppress cultivation, but the effect will last for an hour, during which cultivation cannot be restored.” An Xiaoyu took out two pills, but from her eyes, it was clear that she did not want to use them.

“Okay, I’ll go. You stay down here and support me!” Jiang Yuan decided immediately. This kind of thing shouldn’t be risked by a woman. Besides, An Xiaoyu is at the Divine Realm, and her combat power will be even greater later on.

“No way!” An Xiaoyu shook her head. She continued, “I checked the hotel’s attendance records. The supervisor and the cleaning staff who went to the 108th floor arrived at almost the same time. It won’t work if one person goes alone. It’s even riskier to disguise oneself as another person.”

"Then what should we do?" Jiang Yuan didn't like doing infiltration missions because they were too troublesome, had long mission cycles, and didn't yield high rewards.

“We can only do it together. We’ll hide the supervisor and the cleaning staff first, then enter the 108th floor as them. They only have half an hour to clean, so we need to try to finish the task within that time,” An Xiaoyu said.

"It's a bit risky, but it's the only way we can do it now!" Jiang Yuan had no choice but to agree to this plan, because it was the only plan that could complete the mission the fastest at the moment.

"There are still twenty minutes before the shift handover. Let's take a break and then try to intercept the substitution in the last five minutes."

After An Xiaoyu finished speaking, the two fell into a silent stare.
