216 The Stone Cave Mechanism. I’m Going To Look For Him

Sun Jianxiong, Bo Zhan, and the group were bewildered again by Professor Su's words, especially Sun Jianxiong who realized the oddity first. He continued asking the old man, "That's not right. Professor Su, you said that one has to stay a year here to pass through the stone gate. Even the first ones who've explored and came down here have at most stayed a few months?"

"I mean, how is it possible that the young man has already gone through the stone gate?" Sun Jianxiong verbalized his doubt.

After all, they, including Yun Jian, had just arrived here. They had no knowledge of what happened here in the crypt recently.

"Let me finish." Professor Su swallowed.

He looked high in spirit at once as his zestful gaze looked toward the group. "Stay here for one year and go through the stone gate is only one of the options."

"You mean there's another choice?" It was Yun Jian who posed the question this time.
