When Dongfang Shitian had just completed Thunder Abyss, the Dongfang Family held a huge advantage over Misty Pavilion. In particular, they had the chance to stockpile many trump-card items such as Group Blessing Scrolls. These items could play a crucial role when they faced Misty Pavilion in the future, perhaps even completely suppressing Misty Pavilion and causing it to collapse.
However, everything changed with the system announcements after Underworld Soldier Invasion ended. At this point, even without sending scouts to investigate, the Dongfang Family knew that Misty Pavilion had surpassed them in the number of trump-card items such as Group Blessing Scrolls. On top of that, Ye Luo and Breaking Waves Riding Wind had obtained national weapons, pushing their equipment levels beyond Dongfang Shitian's. Misty Pavilion's overall strength had now far surpassed that of the Dongfang Family.
The biggest problem was that, because the Game Department had stationed personnel there, it was no longer so easy for the Dongfang Family to hide trump-card items such as Group Blessing Scrolls. Their plan to use the national war to wear down Misty Pavilion while Dongfang Shitian secretly stockpiled trump cards, eventually giving them far more than Misty Pavilion, was no longer viable. Barring surprises, if the two guilds fought after the national war ended, Misty Pavilion would most likely emerge victorious.
Of course, even "most likely" was an optimistic assessment for the Dongfang Family. According to analyses by Dongfang Mingxing and the others, they had concluded that they would have almost no chance of winning against Misty Pavilion in the future. Even if the Ouyang Family, Yinian Family, and Heavenly Kill Organization stood with them against Misty Pavilion, it would still be the same.
This made Dongfang Lu Tian sigh that Dongfang Shitian's completion of Thunder Abyss had truly been a case
