If Zhou Tian could, he would naturally prefer not to take any risks.
However, given the current situation, Zhou Tian was well aware that defeating those ancient powerful beings without taking risks was simply impossible. Hence, even though he knew the risks involved in his actions, he still decided to strike against those ancient warriors to achieve his goal.
After having waited for so long, it was certain that Zhou Tian had not come away empty-handed.
After all, even if those ancient powerful beings were strong, they were not machines. They would inevitably have their moments of laxity. At that time, if those beings showed any slackness, even for a moment, Zhou Tian could seize that opportunity to counterattack. With Zhou Tian's strength, as long as he was careful not to give those ancient beings any chance to counterattack, there should be no problem in taking any of them down.
