Liu Longtao, having successfully crossed the Tribulation at the Wudang Mountain base, threw a lavish banquet that many leaders from the Dingbei Army attended.
The reason for the banquet was simple: to celebrate Lord Master's successful Tribulation Crossing, and the addition of another Golden Core True Man to Lu Country.
This reason was unproblematic since promoting the newly emerged Golden Core True Man's title was highly beneficial for deterring the petty and weak within Lu Country.
The only potential criticism lay in the fact that Yan Yu, the first to undergo the Tribulation, had done so stealthily, celebrating his Core Formation quietly without much fanfare, while you, the second, are making a big show of it, as if you wish the whole world to know.
