Doing the same thing all the time can be tiring, but increasing your wealth all the time is exciting.

After a few days of excavation, Emperor Jitian had obtained hundreds of catties of ice crystals, but the veins seemed to have only been dug up the tip of the iceberg.

The ice crystal ore is not heavy, hundreds of catties are piled together, but there is a large pile, just dig up the ice crystals now and sell them, and the emperor can squander them for a hundred years.

The cold air in the veins was heavy, and many blue spots appeared on the bones of some skeleton warriors who excavated the ice crystal ore, but the spots were too small for Emperor Killing Heaven and the five undead bosses to find.

When many of the skeletons were stained with white spots, the Emperor finally saw it.

Capturing one of the most serious skeleton warriors, the Emperor Slayer Heaven studied, and there was frost in the white spots.

The aura of frost is attached to the bones, why is this happening?

Emperor Jitian communicated with the undead warrior with his consciousness, only to learn that this undead warrior had dug up a lot of ice crystal mines, and many times the bone body came into contact with the ice crystals, and a little frost qi would be left on the bone body, and when it was exposed a few more times, the frost qi would become more and more.

Emperor Killing Heaven didn't know if it would be harmful if this bone body was contaminated with frost qi, only skeleton undead and zombies, ghosts and nightmare knights were not contaminated with frost qi.

Ghosts have no disembodiment, Nightmare Knights have Nightmare Fire, and the Frost cannot erode them.

Fearing that the Frost would be harmful to the undead, Emperor Kill Heaven asked the Zombie King and the Ghost King to take the skeleton creatures and zombies away from the mines.

"Young master! What's going on! "Skeletron has a lot of nerves, if the Emperor doesn't say it, he hasn't noticed the strangeness of the skeleton undead.

Emperor Heaven Killer said: "Skeletons and zombies are all contaminated with frost qi, if frost qi is harmful to them, we will lose a lot!"

The zombie king said: "Young master, once a powerful frost bone dragon appeared in the Death God Realm, and there was frost qi on its bones, and I saw that frost qi may not be harmful to the undead."

Emperor Killing Heaven said: "We are not sure that the frost qi will cause harm to the undead, the number of undead is too much, I can't let them take risks, in order to test whether the frost qi is harmful, I want to take a skeleton warrior for experiments."

Emperor Killing Heaven's opinion, the Zombie King and Skeleton King will not object, and as he spoke, Emperor Killing Heaven selected a skeleton warrior with the heaviest frost qi on his bones, took out a piece of ice crystal ore and put it on the skeleton warrior's hand bones, and then observed.

The frost qi in the cryolite ore slowly melts into the skeleton warrior's bones, and since the cryolite has been attached to the bones, the frost qi enters the bones of the undead warrior faster.

This piece of cryolite, which is only the size of a fingernail, contains a large amount of pure frost qi, and after the hand bones of the undead warrior absorb the power of the cryolite, Sen Bai's bones turn blue, and a layer of frost adheres to the hand bones.

Half an hour passed, the cryolite turned into a transparent stone, and Emperor Jitian looked at the skeleton warrior's right arm bone in surprise, the entire arm bone turned completely blue, and it was still cold.

"Try it, can you still control your arm bones?" Emperor Slayer said to the undead warriors.

The undead warrior waved his bone arm, and his movements were completely unaffected, and the emperor was interested, and at the same time took five cryolites, and let the undead warrior lie down.

Place one Cryocrystall Ore on each of the Undead Warrior's left arm and legs, and then two more Cryocrystals in the Undead Warrior's chest.

The cold air eroded the bones, and when all the frost power in the cryolites was gone, the five cryolites turned into ordinary transparent stones, and the skeleton warriors turned azure except for the skull bones, and they were still cold.

The Skeleton Warrior's actions were not affected in any way, and the Emperor Killing Heaven grinned, this would not make the Skeleton Warrior into the Frost Bone Dragon by mistake, right?

The more he thought about it, the more excited he became, Emperor Killing Heaven took an ice crystal ore and stuffed it into the eyes of the undead warrior, this time Emperor Killing Heaven was surprised, the frost power in the ice crystal stone quickly disappeared, and the skull of the undead warrior did not turn into the imaginary blue skull.

Emperor Killer took two more cryolites and stuffed them into the skeleton warrior's eye sockets, and the skeleton warrior's skull finally reacted, and a layer of frost appeared on the skull.

But it's just frost, the skull is still white, and the emperor doesn't believe in this evil anymore, and stuffs cryolites into the skull bones of the skeleton warriors.

"Ah~!"

The Skeleton Warrior's soul screamed, and then the Skeleton Warrior did not react.

He's dead? Emperor Killing Heaven looked at the unresponsive skeleton warrior, and his heart tightened, this frost aura seemed to be harmful to the undead.

"Huh?"

I thought that the skeleton warrior had gloriously dedicated himself to the experiment, but the skeleton warrior's whole skeleton trembled, and the white skull began to turn blue.

The blue crystal bone body lay on the ground trembling, and the Emperor Slayer Heaven sensed that the soul fire of the undead warrior had changed, the original green soul fire turned blue, and the green flame that had been bubbling before became a blue cold flame.

The Skeleton Warrior stood upright, each shooting a frost arrow from each of its eye sockets.

Startled, Emperor Jitian dodged two frost arrows, which shot at the rock of the cave wall, and two-thirds of the ice arrows sank directly into the solid rock.

"What's going on?" Emperor Slayer glanced at the powerful ice arrow, turned to ask the skeleton warrior.

The skeleton warrior shook his head vigorously, and then said, "Lord Death, a shadow appeared in my mind just now, I seem to be a magician, so I released a magic arrow!"

"This ......!" Emperor Killer was taken aback, according to what the Skeleton Warrior said, it was the Skeleton Warrior who had a memory from his life and released his magic with the breath of frost.

Emperor Jitian called the Death Knight who had the memories of his life and asked, "Death Knight, can this undead creature use the abilities it learned when he was born with the memories of his life?"

The Death Knight said: "Young master, it's like this, generally skeleton undead have no pre-mortem memory, when the pre-mortem memory is retrieved, then the skeleton undead will mutate, and the mutated undead can use the skills of the pre-mortem." Just like me! Once I have regained my memories from my life, I will be able to use my wisdom to create a bone horse and use the charging skills that my knights used in life. ”

"Retrieving your memory is equivalent to awakening, and awakening is equivalent to becoming stronger, hehe!" Emperor Jitian laughed happily.

The soul of the Frost Skull Undead was a mage before he was alive, so he could use the Frost Qi to cast magic, so wouldn't he be a Fighting Qi warrior before his death be able to use the Ice Fighting Qi?
