"This is..."
"Heaven and Earth Dao Sound?"
As Lu Qing and the elder doctor were about to study the poison blood, they felt this grand fluctuation of heaven and earth. First, they were startled, then expressions of shock appeared on their faces.
It was because they discovered that this fluctuation of heaven and earth was identical to the Heaven and Earth Dao Sound that had marked the beginning of the changes in the Heaven and Earth Rules.
Immediately, neither of them cared to study the poison blood anymore.
They hastily left the room and looked up at the sky.
"Brother!"
Little Yan, holding Little Li, ran out from the room.
Clearly, she and Little Li had also heard the Heaven and Earth Dao Sound.
"Mr. Lu!" At this moment, Hu Zezhi, limping from his own room, appeared with a trace of panic on his face, "What is this sound?"
"I'll explain it to you later, let's go to the rooftop first."
