It was clear that Zhou Tian was always prompt in returning to the main plane after entering the Ancient Ruins Space. So, when he didn't return for a long time, people assumed he was trapped there. In fact, the rumor wasn't wrong; Zhou Tian indeed got trapped in the Ancient Ruins Space.
As a result, because Zhou Tian was continually trapped and didn't have any advanced arrangements, minor bosses like Zhang San hoped to succeed him after his 'death'.
Because Zhou Tian didn't make plans for such a scenario, all the minor bosses were eying his Boss Position. This eventually led to rivalries and the creation of grudges, resulting in the current predicament, which wasn't surprising at all.
Upon understanding all this, Zhou Tian realized he had nothing significant to be angry about.
