Zhang Ruochen wouldn't let all the Immortal Vampires attack together. It was too risky to deal with Que. Besides, Que cultivated the Path of Oblivion. An army wouldn't be effective against him.
Only Lady Wind, Lord Bladehell, Lord Sinluo, and Yue Tinghai were traveling with Zhang Ruochen.
Lord Xia Yu stayed on the home planet and continued to set up the array.
Taking the Emperor Grade Saintwill Pill represented Zhang Ruochen's personal interests, not the interests of the entire Immortal Vampires.
Lord Bladehell and Yue Tinghai were willing to help Zhang Ruochen because they had no choice. After all, both of them had participated in the plan to attack the Bloodysky Continent.
If Zhang Ruochen wanted to take revenge on them, he would definitely send them to charge into the battle and do the most dangerous thing.
