Upon hearing these words, the breathing of the people present became significantly heavier.
"Raising the price" was merely a euphemism, as any killer organization capable of assassinating someone at the Tao Foundation Stage wasn't just short on money, but also on those precious resources monopolized by various powers:
Elixirs, Implants, Protective Clothing, Abnormal Weapons, Secret Manuals...
The initial offer made by the Lu Family was already quite generous, or else these people wouldn't have risked the danger of killing an Imperial Envoy for the task.
To double the original offer would mean an astronomical sum if it were to be converted into money!
And many of these items could not be purchased with money at all.
This couldn't help but make the leader of the killer organization somewhat dubious:
"Can the employer afford this price? How are they guaranteeing it?"
