Even though the fixed event of the Sea of Zombies had suddenly erupted, he had left Black Boss's signal-jamming zone, and he had already sent a message to Chen Miao.
Enveloped by such a vast number of zombies, he had given up hope of Chen Miao coming to save him.
He merely wanted to inform Chen Miao of the situation.
In case he or Black Doctor didn't withstand the torture and divulged the 'Tomb Guardian's' Faction Effect, at least Chen Miao should know who the informed parties were, to be ready to silence them at a moment's notice.
Anyone who knew of the Tomb Guardian's Faction Effect would realize, if they had any sense, not to let the information leak easily.
Whether they planned to sell this information to others or to seize the power for themselves and then sell the empty shell of power, it promised to be a considerable profit.
By then, silencing these people as quickly as possible would help to contain the spread of the news within a small scope.
