Kang Yifei looked at the corpse on the ground, as well as the now transparent figure, and found that he had changed from a zombie to a ghost. And his intuition told him that the brain glowing with green runes was the material basis for his ghostly existence.

It was those green runes that protected his brain from dying. But these runes need energy, and if they can't find the energy to sustain the runes, the day the runes are broken will be when he dies.

Uh, well, although he's already died once, oh no, maybe twice, but he doesn't want to die a third time, and if he dies again he's going to be gone forever.

At this time, there was a sudden sound of people outside, and it turned out to be someone sent by Xing Haifeng to clean up the factory. But these people couldn't stand the hellish scene of the factory full of internal organs and flesh and the rancid smell of blood, and vomited on the spot.

"Xing Haifeng, this shit, actually let us clean up this ghost place!"

"But, Boss. He won't give us food until he finishes his work! ”

"Hey, I'll give you food now, can you eat?" The boss asked rhetorically, and then he thought for a moment and said, "Let's just set a fire." Cut off the dead branches casually, set them on fire and throw them inside. ”

Taking advantage of the efforts of those people to collect firewood, Kang Yifei used his newfound magic to prop up his brain and hid in a hidden underground laboratory.

The underground laboratory without lights is nowhere to be seen, but for Kang Yifei in ghost form, it is not a matter at all. He carefully closed the basement entrance, hid his brain, and found a strange box in the corner of the underground lab. The box is densely covered with all kinds of runes and prohibitions, and at Kang Yifei's level, he can't understand it at all, this is the legendary lich's life box.

At the beginning, the lich didn't trust a few necromancers under him, so he handed over his life box to Kang Yi, who was familiar with the surrounding environment and looked powerless, to fly and hide.

A lich's weak voice came from the lifebox: "Ah! Little girl, uh, how did you become like this? Are the humans out there gone? ”

Kang Yifei shook his head.

"Oh, that's too bad. My mission has failed, and the master will not let me go! Perhaps, I can only reduce my punishment by offering you to my master. I cursed the other groups for failing as well! ”

Kang Yifei's expression moved, and he pointed to it.

"Huh? You mean......"

Kang Yifei made another explosive gesture and pointed at it again.

"You're saying to tell the humans the other sets of information and let the humans clean them up? Aha, you're terrible at that, but I like it! The lich laughed, "But how do I get the word out to the humans?" ”

Kang Yifei found a pen and paper and signaled that he could draw it.

"Several of our groups are positioned to form a pentagram. We are in the lower left corner of the pentagram, and the distance between each group is about 8 miles. ”

"What1 is about how long is it? 1 is more than 5,000 feet, and a foot is about the length of my life box. ”

Kang Yifei quickly estimated that the one mile that the lich said was almost 1 mile, that is, 1.6 kilometers. Then, 8 miles is 12.8 kilometers. He didn't know the exact size of his city, so he could only draw a five-pointed star and mark the distance between the five corners about 12.8 kilometers. Finally, write "Distribution Map of Undead Natural Disasters" at the top, and write the words "Jinma Pharmaceutical Group" in the lower left corner.

Because writing with a mind is completely different from handwriting, Kang Yifei's picture is crooked, but the general meaning can still be seen.

After doing this, Kang Yifei sneaked out of the basement to take a look. The factory was set on fire, but only half of it was burned to the door. The fire couldn't even burn the office where his zombie corpses were, and it had no effect on the underground laboratory deep in the factory.

Upon returning to report, the lich suddenly asked, "Are there any intact corpses nearby?" ”

Kang Yifei thought for a moment and pointed to himself.

"Ahh That's right, you've become a ghost, so lend me your body. ”

Kang Yifei floated a piece of paper with his mind and moved the chair again, indicating that he could only move very light things.

The lich said helplessly, "Okay, I'll teach you the basic operation spells first. Of course, before I can do that, I'll have to teach you how to speak in a spirit state. ”

Kang Yifei may indeed be very talented in magic, and it only took him four hours to learn what the lich taught. Moreover, his evolutionary skills can also be used on himself, making his spirit form more condensed and magically adaptable.

Like the evolution core that Xiang Ningxuan obtained, the energy he needed for each evolution would be doubled, and basically after three evolutions, his reserve energy would be exhausted.

By this time it was already dark, and the flames outside had been extinguished. Kang Yifei's ghost body passed directly through the door of the underground laboratory, came to his zombie corpse on the second floor, and used the operation spell he had just learned to drag the corpse back to the underground laboratory with great difficulty.

"Alright! You go out first. "The lich taught Kang Yifei magic for four hours, and he was also relatively tired, and he was anxious to occupy a body to regain his strength. Kang Yifei's talent is so good, his body may have very good spell adaptability.

After the lich drove Kang Yifei out, he used the remaining mana to create a protective barrier and seal off the small underground laboratory. That's when he started casting spells and opened his life box.

The seals of the life box were unsealed one by one, and with a final snort, it popped open, containing the ashes of the original lich. An emaciated middle-aged man, gray-haired and dressed in a violet robe, floated out of it, indicating that he had once been a mage of Dalaran.

He slowly floated to the corpse of Kang Yifei's zombie, and then lay flat on the corpse, casting a spell to sink his soul.

Just as the Lich's phantom sank completely into the corpse beneath, the mutation struck. Another phantom suddenly appeared, and quickly floated to the lich's life box, and with a thought, the life box fell to the ground, and all the ashes inside were spilled.

The lich suddenly exclaimed in fear, "No! Hell, how did you end up here? I've cast a protective spell, you can't get in! By the end, his strength had dried up, and his voice had become erratic. But he struggled to get the ashes back into the life box.

With a wave of his hand, a gust of wind blew towards the lich's ashes, completely blowing them away.

"Ah~" The lich's phantom screamed as it dissipated, and a purple-black book fell to the ground.

Kang Yifei confirmed that the lich was dead, and stepped forward to pick up the purple-black book. This is actually the lich's spellbook, which contains a large number of spell models and principles.

Kang Yifei took his brain out of the hidden place, put it in the life box, and carefully sealed it. This brain was his natal thing, and it was through it that he came in directly bypassing the Lich's defensive circle.

He picked up the lich's spellbook and read it voraciously. It wasn't until dawn that he saw the map of the undead scourge that he had drawn, so he put away the spell book and floated out.
