Shi Xiaobai took a deep breath and began to feel slightly pressured. The first few waves of demonic beasts were not strong, but they came in large numbers. Furthermore, they attacked the Tree of Life without regard for their lives. They ignored his attacks.
Shi Xiaobai did not need a long time to destroy all the Nerubian Spiders, but he could not guarantee the safety of the Tree of Life during this period of time. And based on the situation from before, the Tree of Life started off extremely weak.
Shi Xiaobai remembered that he saw an exchange option, 'Upgrade Tree of Life' in the Points Treasury. Therefore, it was obvious that upgrading the Tree of Life was necessary if one wanted to defend for a prolonged period of time. The chewing of a few Forest Wolves had managed to turn half of the initial Tree of Life gray. And for future waves, probably a prod on the initial Tree of Life would doom it.
