Cultivating

Jian has given instructions to Zhou You and the system has informed him that Zhou You has closed off the Alchemy Hall.

So now that everything is clear in Zhou You's side Jian focused on himself. As he also had to start Cultivating so that he can reach Core Formation Fourth Realm before he upgrades the sect.

Since he wanted to increase his cultivation at certain Jian had to find other ways because his main cultivation technique requires him to complete the cultivation cycle.

So to complete the cycles it requires time and resources. So he didn't wanted to waste resources and time on increasing his cultivation. 

Even though he had more than enough time to cultivate he wanted speed up the process so that he focus on some other things.

Since he didn't know any other way he decided to ask for the system suggestion and to see if the system can provide with a way to increase the cultivation.
