Like the internal environment of the Xingdu barrier, there is also some kind of environmental adjustment device in this floating island called "Xingdu Academy of Sciences High Energy Physics Testing Field".

The surrounding temperature, humidity, air pressure, environmental brightness, etc. are perfectly maintained at the most suitable level for human activities. Even the air is very fresh. Lu Yang can even feel the breeze with a smell of plants and soil, blew through his cheeks from time to time, and there is no feeling of being in a confined space at all.

"Everyone is alert. The ancient facilities here seem to be able to operate normally. It is not ruled out that there are ancient automatic defense devices that are in an active state." Facing the empty corridor, he loudly reminded everyone in the team, "Ma Zheng, can you feel the fluctuations of the spiritual energy around you? If there is any abnormal situation, please tell me immediately."

"There is no breath of living people in the passage." As the strongest man in the team, Ma Tianyi took the lead and walked in front of the six-person team. At the same time, a strange wave of spiritual power continued to emit around him, sweeping across the entire passage like ultrasound. "But I could clearly feel that there are many hidden secret doors on both sides of this passage. These secret doors can block my divine consciousness perception. Even if I cross the infinite sea of ​​the void, I can't get around these secret doors."

The divine thoughts (the sixth sense) of the powerful man in the Nascent Soul stage can cross the four-dimensional space to feel the changes in the spiritual environment, which is even stronger than the ultrasonic radar of a bat. Lu Yang did not question Ma Tianyi's statement, but asked directly: "Can this place even block the detection of the four-dimensional space level? Where are the secret doors you mentioned?"

Ma Tianyi pointed to an ordinary wall about five meters in front of everyone and said, "The nearest door is here!"

It seemed as if I could feel the thoughts of Lu Yang and others. As soon as Ma Tianyi finished speaking, a metal groove suddenly stretched out of the silver-white metal wall.

Lu Yang stared at the sudden appearance of the groove and observed it carefully for a while, and found that the size of the groove was almost exactly the same as the identity verification card hanging on Ling Xiao’s chest.

"Is this what we meant by swiping our card?"

Under Lu Yang's instructions, Ling Xiao carefully placed his special identity verification card on this groove. Sure enough, the two were closely matched together, and it could even be said to be directly integrated into one.

As a blast of red light flashed through the surface of the identity verification card, the prompt sound of the high-energy physical test field came again:

"Identity verification error, cardholder does not have permission to enter this area!"

Obviously, in this floating test site, Ling Xiao’s identity verification card is not a universal pass.

Seeing this, Xuefeng turned his head and asked, "Lu Yang, what do you think? Should you try to make a forced breakthrough?"

Lu Yang touched his chin and analyzed: "Xinghu City itself is already very strange, and this floating island is obviously the core area of ​​Xinghu City. We should be more cautious and not interfere with its normal operation. After all, this so-called logical completeness joint test has been run back and forth for more than 20,000 times without any failure. As long as we don't mess around, there should be no major problems. Our top priority now is to find Ling Xiao's 'working location' first. Only by finding her work location will this high-energy physics test site reveal some useful information to us."

"Are we just trying it out with one door?"

Lu Yang nodded and said, "This is also a method. There are only so many rooms here. After trying them one by one, you can always find Ling Xiao's so-called 'working location'. According to known information, Ling Xiao's job should be to monitor the operation of this logical complete joint test. This permission should sound not low. If you really can't get in some irrelevant places, it's fine."

Xue Feng always felt a little worried: "Will you miss any important information like this? After all, outsiders are not allowed to enter these places casually, and maybe there are some important secrets hidden inside."

Lu Yang said without caring: "The women's toilet on earth is not allowed to enter the women's toilet at will, but this does not mean that there must be any shocking secrets hidden in the women's toilet! Maybe this is just the private office of other employees, which is used to store their own personal belongings, so outsiders are not allowed to enter..."

What Lu Yang said is reasonable and others have no objection.

So everyone followed Ma Tianyi's instructions and asked Ling Xiao to use his identity verification card to test the hidden secret doors on both sides of the passage one by one.

"Identity verification error, cardholder does not have permission to enter the area..."

"Identity verification error, cardholder does not have permission to enter the area..."

After testing seven or eight secret doors in succession, all of which were prompted to be wrong, when Ling Xiao tried to open the ninth secret door, the high-energy physics test field finally gave a different prompt.

"Identity verification is successful, Miss Ling Xiao, welcome to the employee lounge of the High Energy Physics Testing Floor of Xingdu Academy of Sciences!"

Accompanied by the prompt sound, the secret door slowly opened, revealing a wide hall of thousands of square meters.

Finally, it was no longer the empty appearance in the corridor. The employee rest hall was fully furnished, and a large amount of daily necessities and food were kept intact.

In the middle of the hall are several long metal tables with streamlined shapes, with many strange fruits, hearty foods, and some small bottles with strange pills. Around them are some sofas of unknown materials of different shapes. Judging from the tips of the test site and the decoration form of the room, this should be the special venue for the test site employees to hold a party.

The only dissonance is that the food and fruits in this room are slightly messy.

Some food is as incomplete as if it had been gnawed by a dog, and there is even a lot of food and fruit falling to the ground, just like someone just opened a carnival party in this employee lounge.

Xiao Huang couldn't help but say stammeringly: "This employee lounge looks quite lively."

Xue Feng pointed to the food on the table and asked, "These things look very fresh, but I don't know if they can be eaten!"

Lu Yang did not answer Xue Feng's question, but walked straight to the metal long table.

He picked up a fruit that looked like a peach and looked at it, then squeezed it with his right hand, and a large amount of juice flowed out of his fingers, looking extremely tender.

Seeing this scene, Lu Yang couldn't help but express a surprised expression: "The environment here is so normal, but the fruits show no signs of rotting. Did these fruits be put on these two days?"

Everyone looked at each other when they heard this, and even Xiao Huang and Chenxi didn't understand the reason.

There can't be people living here!

Seeing that no one answered, Lu Yang looked at the fruit food in front of him and boldly guessed: "Can this be some kind of Galaxy Federation preservation black technology that can make the decaying speed of all items extremely slow?"

However, Chenxi's answer was still the same: "Insufficient intelligence, it is impossible to judge."

In this high-energy physics test field, Ma Tianyi's cultivator's sixth sense seemed to be greatly restricted, so he also began to learn from Lu Yang and others' methods and use traditional means to view clues in the room.

He brushed his fingers across the spotless desktop and said thoughtfully: "The room here is not even a little ashes. Even if the air here is extremely clean, there should be some debris caused by rotting food..."

All signs indicate that the employee rest hall does not seem to have been abandoned, and has even been used by people in recent times.

This discovery made Lu Yang feel a little uneasy.

If there are still people here, where are they now?
Chapter completed!
