"Whoo—"
The ancient and heavy horn sounded suddenly, signifying that the beast tide from Immortal Country had come again.
Exhaling a turbid breath, Lin Su was awakened by the horn from his meditation, separating himself from the meditative state. He looked at the slightly dim Space Heart in his grasp and his face took on a smiling expression.
This was the fourth day that Combat Team 19 had arrived at the border battlefront.
And the piece of Space Heart in his hand had been in use for half a month since obtaining it.
During the special training period before, Lin Su had reserved the only rest time for Body Refining; thus, he had no time for meditation in the Blue Star and could only seize the time in the Shenwu world.
But on the battlefield, his time was more flexible. Apart from leading the entire team to the frontline at a frequency of once a day to repel the boundless tide of exotic beasts at the border, the rest of the resting time could be freely arranged.
