Chapter 872

"However, I have the pass with me, but it didn't have any effect just now."

"Of course, it could also be because I didn't take it out or use a special method to activate it."

The four people's thoughts were highly consistent.

Then, this speculation should actually have a high probability.

But whether it was Qin Feng or Beigong Yun, both of them actually carried a pass.

But in fact, the two of them, who carried the pass with them, were treated the same as Zhao Long and had no way to approach this red hill at all.

The pass in Qin Feng's hand was naturally what they had found in the Mist Space back then.

But the pass in Beigong Yun's hand was not something he had sought out himself.

He had been preparing to enter the Kaiyuan Secret Realm all along,

crazily learning and consolidating knowledge about arrays,

and had no time to look for a pass.

Therefore, the heavy responsibility of finding a pass was handed to Beigong Shang, who had good strength but a brain far less capable than Beigong Yun's.

At this moment, the pass in Beigong Yun's hand was the one that Qin Feng and Lin An had given to Beigong Shang.

"When you said you wanted to find a pass, did you say how to use this pass to enter the ancient ruins?"

"Can you just enter by holding it in your hand?"

Qin Feng took the pass out of his storage ring,

held it in his hand, and walked forward a few steps.

It was still the same situation as before.

He had no way to enter the area protected by this barrier.

"There is no intelligence regarding this aspect."

"Now, the only thing we know is that only those holding a pass have the qualification to enter the ancient ruins."

"But in fact, how those holding a pass enter the ancient ruins,"

"and whether those who didn't get a pass have other ways to get in,"

"we haven't obtained any information of this kind."

"The ancient ruins appeared suddenly and are too mysterious."

"No one had ever heard of such a place before; everything is unknown."

Regarding this, neither the Beigong brothers nor the Dean of the Mobis Academy

could give Qin Feng an answer.

They didn't know more about the ancient ruins than Qin Feng did.

In fact, they knew even less than Qin Feng, who possessed a system.

After all, Qin Feng could infer some things from the tasks issued by the system.

"Alright, let's all try."

"Usually, if you want to activate a treasure,"

"you either use Yuan Qi to activate it or use mental power to activate it."

"Mental power activation is too dangerous; it's better to try Yuan Qi first."

Qin Feng tossed the pass in his hand up and down,

treating the pass very casually,

without any of the caution one would have for a treasure.

At the same time, he habitually asked the system:

"System, how do I activate this pass? Input Yuan Qi or mental power?"

"And is the pass the key to opening the barrier and letting us enter this space?"

Ding-dong, the player has asked a question, and the system is providing an answer.

【To activate the pass, you must input both Yuan Qi and mental power simultaneously.】

【Furthermore, the Yuan Qi and mental power must be equal in amount.】

【The amount of Yuan Qi and mental power input determines the degree of activation of the pass.】

【As for whether the pass is the key to entering this space,】

【this question involves mission intelligence; insufficient authority, unable to answer.】

Although the most critical question wasn't answered, Qin Feng finally knew how to use this pass.

However, there was one sentence that made Qin Feng very concerned:

"The amount of Yuan Qi and mental power input determines the degree of activation of the pass."

In other words, the activation of this pass actually has levels and layers.
