After his women had given birth to their children, Liu Yang received a message from the system warning that he could already go through the last tribulation to have reached the peak of power.
Liu Yang did not accept going through tribulation at the moment, as he knew it would be extremely dangerous, as others could try to mess him up and make him fail. Another reason not to do this was that Liu Yang was in the Xiao clan, he needed to return to the Ninth Worlds before because that was where he was born.
Liu Yang did not want to leave his family worried, so he did not say what he was going to do, he just said he would have to travel to the Ninth World for some time before returning, and asked everyone to take care and behave before he came back.
A month before he returned to the Ninth World, Liu Yang spent that time with his women, some of his children, grandchildren, daughters-in-law, and son-in-law. He enjoyed every second with them, his other clones talked about it too.
