Everyone looked at Elder Mei.
Elder Mei was frowning.
Mr. Duan asked, "How long will it take to open this door?"
Elder Mei shook his head. "The formation is very complicated; it'll take me at least seven days!"
Seven days?
Before he could say another word, he sensed a force inside the mine.
Crack!
The heavy bronze door rumbled.
Everyone jumped.
What the hell?
They looked at one another, and all of them moved away from the door.
"Elder Mei, what's going on?" Mr. Yang asked.
Elder Mei was as confused as everyone else.
Seeing the look on Elder Mei's face, Zuo Qingluan tried to save him from the awkward situation. "The Secret Essence Mine has been buried underground for so long; anything could have happened. I'm sure Elder Mei will figure it out soon."
Hearing the crack, Mr. Yang was struck by an idea. "Can it be opened from inside?"
Elder Mei rolled his eyes.
