Chapter 100

Lin Yun rested for a full ten minutes.

After ten minutes, Lin Yun finally recovered from the state of complete exhaustion.

After coming out of the side path, Lin Yun did not check the damaged puppet but immediately went to the side of the Bone Demon's corpse. For Lin Yun, the biggest gain from this trip to the Bone Plane was the early elimination of the Bone Demon. Not only could the mining of the Nether Iron vein be advanced by a month, but the plan to seize the Book of Death could also be advanced by a month.

Although the soul fire had been completely destroyed, when Lin Yun stood next to the Bone Demon's corpse, he still felt a massive force of death emanating from it. After all, this was a once near-Archmage undead creature. Even after the soul fire was completely destroyed, the residual death force was still astonishing.

Lin Yun had long been prepared for the Bone Demon's power, so from beginning to end, he never placed his hopes on the Undead Bane ability. He was not Conqueror Charles, who had once single-handedly exterminated all undead on the Undead Plane. His Undead Bane ability was at most effective against low-level undead. To intimidate a powerful existence like the Bone Demon, which was comparable to an Archmage, he would have to conquer the entire Bone Plane.

Compared to the still poorly understood Undead Bane ability, Lin Yun trusted the magical power he held in his hands more.

"Sure enough, it's still here..." Lin Yun squatted down next to the Bone Demon's corpse and quickly found what he was looking for.

What Lin Yun found was the Bone Demon's ever-present Nether Fire Bombs.

Don't underestimate these Nether Fire Bombs. A major reason the Bone Demon's combat power rivaled that of an Archmage was because of these bombs. They were formed from death force and had been around the Bone Demon for countless years, long enough to be tainted with the unique corpse poison of undead creatures. In Lin Yun's view, each Nether Fire Bomb was as valuable as a Radiant Magic Tool.

Moreover, they were one-time consumables, with power almost on par with a full-strength attack from a Spirit Magic Tool. Only a puppet made entirely of mithril could withstand several Nether Fire Bombs without falling.

If it were Lin Yun himself, he wouldn't be able to withstand even one.

Lin Yun found a total of twenty-three Nether Fire Bombs next to the Bone Demon's corpse.

After the Bone Demon died, these Nether Fire Bombs, which had lost their source of death force, had turned into black lumps, cold and rough, and at first glance, they seemed unremarkable. But Lin Yun knew that these unremarkable Nether Fire Bombs would immediately burst with astonishing power as soon as a bit of magic power was channeled into them.

Satisfied, Lin Yun put the twenty-three Nether Fire Bombs into his pocket. He still wasn't done and dismantled the Bone Demon's two bone knives, fitting them onto the puppet's arms without hesitation.

Now, this puppet, modeled after a Caucasian combat mage, no longer had the imposing presence it had when Lin Yun first saw it. The mithril plate armor was dented in various places, making it look somewhat comical. More seriously, the mithril skeleton seemed to have twisted, and its movements were no longer as agile as before.

Lin Yun had no good way to repair these damages for the time being. After all, this was the Bone Plane, where all kinds of undead creatures were present, but there were no ready-made repair tools. Lin Yun could only put the puppet aside and plan to repair it after returning to Noscent.

After finishing all this, Lin Yun confirmed again and found that there was indeed nothing else worth looting from the Bone Demon's corpse. Only then did he bend down to pick up the Spirit Staff and the Sage's Chapter...

"What's going on?" Lin Yun felt something was off as soon as he picked up the Sage's Chapter.

Because Lin Yun clearly noticed that the Sage's Chapter now had a third Ultimate Spell slot!

Originally, when the Sage's Chapter fell into Lin Yun's hands, it had only one Ultimate Spell slot. After Lin Yun reaped over a thousand skeleton warriors in the Bone Plane and the Sage's Chapter absorbed a large amount of souls, a second Ultimate Spell slot appeared. Lin Yun had thought that the third Ultimate Spell slot would not appear for a long time, but unexpectedly, after killing the Bone Demon in the cave, that incomplete soul fire actually made the third Ultimate Spell slot appear early!

This was even more important to Lin Yun than the twenty-three Nether Fire Bombs.

Although the explosion of a Nether Fire Bomb was comparable to a full-strength attack from a Spirit Magic Tool, the Sage's Chapter was an Extraordinary-grade component. The appearance of the third Ultimate Spell slot would at least raise Lin Yun's combat power by a level. Without even mentioning other things, just the fact that Lin Yun could have an additional Ultimate Spell in a situation like facing the Bone Demon would likely halve the difficulty of the entire battle.

Perhaps, he wouldn't even need the puppet to intervene.

With three consecutive Ultimate Spells, Lin Yun had at least a fifty percent chance of destroying the Bone Demon's soul fire.

After finishing all this, Lin Yun quickly abandoned the Bone Demon's corpse and brought the puppet outside the cave. Because Lin Yun knew that the greatest gain from this trip to the Bone Plane was not the Archmage and the puppet in the cave, nor the Nether Fire Bombs left by the Bone Demon, or even the two additional Ultimate Spell slots on the Sage's Chapter.

The true gain was at the place where the Bone Demon had been sleeping...

Lin Yun soon bypassed the Nether Iron vein and arrived at the place where the Bone Demon had been sleeping.

For the old Lin Yun, the Bone Demon's sleeping place was a true death zone, where stepping in could cost one's life. But for the current Lin Yun, this place had become a true treasure land. Everyone knew that the Bone Demon only slept in the most concentrated area of death force, and such areas often produced valuable magical materials.

Moreover, over the incredibly long years, the Bone Demon's own death force had continuously tainted these valuable magical materials, and Lin Yun could hardly imagine how far they had grown...

After the Bone Demon broke through the ground, it left a large pit on the black wasteland. The surrounding soil had become abnormally soft, and stepping on it made one sink deep. But Lin Yun seemed to feel no difference, almost impatiently lying down at the edge of the pit and straining his neck to look inside.

Then, Lin Yun saw a black flower in full bloom.
