The roots grew straight downward, extending all the way into the mantle's lava region. From there, they would obtain more heat energy. This was the second step of the plan.
Originally, there had been no need for a first step, but unfortunately, when the two sides had clashed back then, lava had been everywhere in the strata. The roots in most of the layers had been burned away, and the parts that had managed to survive were basically all in the seawater.
The roots advancing downward pushed forward very quickly. After all, the only thing blocking their path was ice, and once a certain amount of hydrochloric acid was added to ice, its freezing point would drop and liquefaction would occur. It was the same principle as scattering salt on a road after it iced over. In essence, the temperature had not changed; what changed was only the liquid's freezing temperature.
During the excavation, the roots often ran into organic remains left behind from its battle with Ming, as well as microorganisms that had not died in the ultra-low temperature but had entered self-induced dormancy instead.
That was an unexpected delight.
Recycling the organic remains could provide Huo Gu with more organic material in this currently barren environment, while the self-dormant microorganisms could be protected for the time being. Once the planet's temperature recovered, they could be scattered across the planet again. After all, he had promised Ming he would help take care of its creations.
"Still haven't hit bottom..."
After excavating for a long time, the roots had continued growing downward. Huo Gu looked back and roughly estimated the distance. From the ice surface downward, they had dug to a depth of nearly four thousand meters.
When digging through the ice layer, besides the obstruction of the ice itself,
