In reality, King Cold Eye and the other five Immortal King experts of the Heavenly Eye World had long noticed everyone from the Sword World.
However, King Cold Eye was fearless and did not care.
Even if the group from the Sword World wanted to stop this, they could not!
There were only four Immortal King experts in the group from the Sword World. The remaining ten were only Perfected Immortals.
Most of the battlefield below was filled with Heaven Immortals and Perfected Immortals fighting. If the four Immortal King experts of the Sword World wanted to save them, it was not appropriate for them to attack personally.
How could the remaining ten Perfected Immortals defend against the hundreds of thousands of troops that consisted of hundreds of Perfected Immortals of the Heavenly Eye World?
Furthermore, even if the four Peak Masters of the Sword World were determined to attack, the six Immortal Kings could still fight them.
