"Nagato, at the current pace of battle, you don't need to worry about running out of energy at all."
Liuhe's voice carried a reassuring confidence.
"As one of Sea Star's Twelve Divine Beasts..."
"Although, because of the rules set by Lord Imu, I can't use my divine office or Divine Power here..."
"I can absorb natural energy from the outside world and convert it into spiritual energy."
Hearing this, Nagato relaxed slightly.
But Liuhe's next words put him on guard again.
"However, there's one thing you must keep in mind."
Liuhe warned him solemnly, "There is an upper limit to the speed at which I can absorb natural energy."
"As long as you maintain your current level of consumption, my spiritual energy is indeed inexhaustible."
"But you cannot suddenly use techniques that consume too much energy."
"For example, creating an even larger Big Ball Rasengan than before, or using Super Shinra Tensei repeatedly within an extremely short period of time."
"Otherwise, there will be a gap in the energy supply, and our fusion mode will automatically be undone."
Nagato listened carefully to Liuhe's voice while staring coldly at Vetto.
Then, unexpectedly, he asked, "Who is Lord Imu?"
"He is the great Creator of Sea Star. He was the one who transformed us from base monsters into true divine beasts."
"Remember, do not casually speak the lord's name to outsiders."
"I understand."
Nagato replied silently in his heart.
Immediately after, his deep Rinnegan narrowed slightly, and his gaze became even calmer and more focused.
Since he could not settle everything in a single stroke...
Then he would see this war of attrition perfectly through to the end.
At the same time...
