Poor Knight

When the giant tree generated by the <Yggdrasil > skill burst through the ceiling, its branches grew monstrously fast and attacked the Orc's. 

The monsters screamed in pain as they were grabbed. The white haired man fell backwards with fright. He tried to control the Orc's to fight back against the branches of the tree, but this effort was useless, because they were regenerating. 

As if it was something easy, the branches lifted the Orc's, which were five meters each. At the top, all monsters were broken in half by the severe squeezing of the branches that filled with life from the blood.

Luke discovered the day he killed dozens of imps that his <Yggdrasil > ability becomes stronger in proportion to the amount of monsters he kills. This fascinated him and made him wonder how strong this skill could become, what the limit was, so he spared no energy to use the skill when he saw the Orc's in a place that the tree would not hinder him, but would help him.
