Original planet, in the western part of the Feather Continent.
Several powerful Grand Yan Immortals were kneeling on the soil under the riverbed, separated from the western region by a river.
The original planet's soil was exceptionally sturdy, and they had only penetrated to a depth of about 10,000 feet underground. Due to the density of the soil, they hid beneath the earth, almost completely isolating their breath. Even top-notch Grand Yan Immortals passing above them wouldn't detect their presence. Of course, nobody else could either.
In the pitch-dark and silent soil, a burly giant slowly opened his eyes.
"Old Nine is almost here, let's get ready to move!" the burly man secretly transmitted his voice.
They had been waiting here for several days for this moment.
"Heh, if things go smoothly this time, my achievements will reach a million!" an elderly man with triangular eyes exclaimed joyfully.
