Jian has finally given the instruction to the system to start the upgrade process of the sect and the system has immediately started to upgrade the items of the sect 1 by 1.
The system has already upgraded the halls and the Herb garden and The Guardian formation. The only thing that is remaining to be upgraded is the spirit vein and after that that the spirit vein is upgraded the system will initiate the tribulation for two star sect.
So after upgrading everything the system has immediately informed Jian that the system has initiated an upgrade of the spiritual vein so Jain should prepare disciples for the tribulation.
Because the spirit vein is going to face tribulation it can affect All disciples who are within the range of the spiritual vein.
That's why Jian has gathered everyone in the disciple's area and immediately after getting confirmation from the system he told them to focus on meditation and don't pay attention to anything else.
