Powerful World Tree Heart Fragment
Bai Zemin naturally had no idea about what had happened in Russia, and he probably wouldn't care too much even if he did know. This was because regardless of whether the Russian Leader became a powerful zombie with extremely terrifying poisoning capabilities, Bai Zemin was still not afraid of any zombies.
Forget about the fact that Bai Zemin's most important records could not be modified or damaged at all or the fact that Immortal Blood Radiance would restore his records if they were corrupted, he even had the Limitless Pagoda that allowed him to bring back the records of other living beings to their base without letting that individual lose power.
After clashing with the Saint of the Absolute and deciding the winner, Bai Zemin led his troops 250 kilometers back from the Mana Eater Tree. After giving several instructions, he left Kang Lan and the others to take over the fort on Russian soil.
