Why level up in isekai, when you can hack your way through

Chapter 7 - Hacking my way through (Part 2)

I guess this is it then...

Instant Kill [OFF]

A Giant tree with a horrid hollow face... stares at me as it shouts a high-pitched cry that spreads dread in the air.

A new entry in "Encyclopedia" Pops up,

"[Rotten Greatwood Elder Tree]"

I really wanna use that staff, but I don't have any magic spells or experience.

I guess I have no choice...

Summons Undead Sage

...

Well, he doesn't look confused, but he's shivering in fear seeing me.

I don't think he's ever gonna be normal, it's time I scold him.

HEY! Stop quivering in fear, you serve me now! Fight for me!

Shivers more violently

Ahh! Well, that didn't do well...

Then I just told him, "I don't know what you think, nor do I care but I'm going to reach the end and leave this place. It's up to you whether you want to follow or rot here for the next hundred millennia." Then proceeded to attack the tree.

I started with "Consume" to gain all I could, then leaped backward by shooting "Venom Spit" while staying air using "Levitate" but I had already expected the poison wouldn't work since it rotten.

Nor would the Divine Blessings work since the tree does not consist of any unholy/dark magic. I could try reversing or disabling his rot attacks using "Rot Manipulation" but I don't think it would work since it has been rotting for thousands of years, it is the source of all the rotting monsters.

I need something effective if only I had some fire magic or any fiery skills, I wish I could convince the sage to fight alongside me. If I want to kill that tree fair and square, I need that giant necro-energy sphere.

And right when I thought of turning my face towards that quivering old sage for help. To my surprise, that old undead coot was already preparing that huge attack.

Perhaps my words touched him.

But now I know what I need to do, the tree could groan all the wants but I need to keep his attention towards me.

The Giant Rotten Tree Violently spreads its giant root all across attacking wildly

I don't know if this will work nor do I want to try but I have a skill that might work to keep his attention towards me.

Approaches near the tree's face and then... bites it using "Feral Bite"...

Ugh!!!!!!!!! Pukes

God ugh!!!!! That was pretty fucking disgusting...

But I was right, I enranged him as he seeped something awfully smelling and hazardous where I bit it.

I don't think "Consume" gave me any liquid substance... should I try once again?

Consume!

[Alert: You Have Obtained Rotten Ichor]

I knew it! I got something new, I have to keep this thing in mind....

Ack!!!!!!!!

The enraged tree struck with one of its giant roots, throwing so far away.

Well, I can't feel any pain and I have "Heightened Sense" and "Almighty Resistance" active all the time after hacks.

But still making sounds like getting hurt makes me feel human.
