Ironclad? Submarine?

The next day.

Lin Yan was about to ask Liu Lanqing if the patrolling would continue. The moment he went out, he met Yu Qian and Jiao Liang.

'They're back?'

Yu Qian walked in front while Jiao Liang followed her with a smile. From time to time, he would talk to Yu Qian, but Yu Qian kept a distance from him and ignored him.

"Senior Brother Lin!"

Seeing Lin Yan, Yu Qian's eyes lit up. She walked up quickly. "Senior Brother Lin, long time no see."

Lin Yan nodded at her. It was obvious that Jiao Liang felt resentful.

"Jiao Liang, I heard that the Spirit Marrow buried this time is only first-grade. It corresponds to the strength of the Tough Realm. Aren't you already at the Tough Realm?"

Jiao Liang scratched his head. "Well, it would be a waste not to bury it."
