Zhang Tie didn't enter Zhang Su's room; instead, with a smile, he passed a space-teleportation finger ring to Zhang Su as he said, "There are enough Demons-fire Pills and All-spirits Liquid, some secret books inside it. In addition, I've put some ordinary books inside; you could kill time with them. As you will stay in the tower of time for 2 decades, with these items, if you concentrate on cultivation, you would definitely promote to a knight!"
Zhang Su threw a glance at Zhang Tie as he nodded forcefully. After that, he put away the space-teleportation finger ring.
At this moment, "thanks" was needless.
"I will promote!" Zhang Su said in a muffled voice.
