Yang Dingtian quickly locked onto a sixteenth-level undead.
Then, he summoned the Million Spirit Demonic Fire, Demon Spirit Demonic Fire, and Void-splitting Fire.
After infusing enough Qi, the three Mystic Fires suddenly rushed into the sky.
Then, they violently collided in the air.
"Boom!"
Suddenly, the incomparably powerful Three Mystic Fire Lightning directly bombarded the sixteenth-level undead.
Suddenly, a terrible light tore through the night sky again, like a nuclear explosion.
During the whole process, the sixteenth-level undead stood still.
In an instant, it was directly turned into ashes. From the beginning to the end, it did not resist at all. It did not even try to escape.
Yang Dingtian's Three Mystic Fire Lightning was indeed powerful. It could actually directly destroy a sixteenth-level undead.
There was a sixteenth-level Hell Magic Crystal floating in the air. Yang Dingtian immediately went over, collected it, and threw it into the Soul Ring.
After destroying the sixteenth-level undead, Yang Dingtian began to sit down and recover his Qi for battle.
After only a quarter of an hour, his Qi for battle was completely recovered.
Then, he used the Three Mystic Fire Lightning to destroy another sixteenth-level undead.
Then, there was another sixteenth-level Hell Magic Crystal in Yang Dingtian's Soul Ring.
He sat down again, swallowed a Mystic Gathering Pill, and recovered his Qi for battle.
At this time, there were only five fifteenth-level undead left.
After recovering all his Qi for battle, Yang Dingtian locked onto three fifteenth-level undead and then bombarded them with the Three Mystic Fire Lightning.
"Boom!"
Once again, there was a light like a nuclear explosion. The terrible Three Mystic Fire Lightning directly bombarded the three fifteenth-level undead.
Then, the night sky hundreds of miles away was as bright as day again.
After nearly a minute, the light dissipated.
Yang Dingtian found that the three fifteenth-level undead were actually not turned into ashes. They were just crazily trembling on the spot. Just a little bit more.
It seemed that Yang Dingtian's Three Mystic Fire Lightning was not enough to destroy three fifteenth-level undead at the same time.
So, after Yang Dingtian recovered his Qi for battle, he bombarded them again.
The three fifteenth-level undead were officially turned into ashes.
Yang Dingtian had obtained three more 15th Tier Hell Magic Crystals!
Next, after Yang Dingtian recovered his Battle Qi, he used the Three Profound Fire Lightning to eliminate the remaining two fifth-level undead creatures.
It would be difficult to kill three at the same time, but two wasn't a problem.
The first wave of crazy hunting had ended.
Yang Dingtian obtained a total of two 16th Tier and five 15th Tier Hell Mana Crystals.
…
Yang Dingtian once again moved towards the periphery.
It didn't take long for them to encounter a huge wave of specters. There were hundreds of specters at the twelfth, thirteenth, fourteenth, and even fifteenth level.
At this moment, these undead were crazily killing and devouring each other.
Yang Dingtian rushed into the center of this pile of undead spirits.
In an instant, the hundreds of undead froze in place, unable to move at all.
The death aura of a level-18 undead instantly suppressed them.
Then, the Undead waited for Yang Dingtian's verdict.
He had struck it rich!
Although this wave wasn't as high level as the first wave, the twelfth-level Hell Magic Crystals were what Yang Dingtian needed.
Yang Dingtian directly released the Three Profound Fire Lightning to the extreme, and then violently blasted it down.
This time, it wasn't targeted at one or a few undead creatures, but all hundreds of them.
"Boom!"
Once again, the terrifying light tore through the sky.
Then, hundreds of low-level undead creatures were all turned into ashes.
Yang Dingtian sat down cross-legged, recovered his Battle Qi, and then quickly released the Second Profound Fire Lightning.
Suddenly, dozens of undead creatures were turned into ashes.
Next, Yang Dingtian released the Three Profound Fire Lightning fifteen times, spending two and a half hours.
Finally, this wave of undead creatures was completely wiped out.
Hundreds of different kinds of Hell Magic Crystals floated in the air.
Yang Dingtian quickly collected these Hell Magic Crystals, and then sent them all into the Soul Ring.
After recovering his Battle Qi, he once again rushed outside to kill the third wave of undead creatures!
…
Two hundred miles later!
Yang Dingtian encountered the third large-scale gathering of undead creatures!
This time, it was even crazier, with a total of one to two thousand undead creatures.
However, their levels would be much lower!
The highest were only twelfth-level undead creatures, with some eleventh-level undead creatures, and most of them were ninth-level and tenth-level undead creatures.
At this time, these undead creatures were completely in a mess.
And after Yang Dingtian rushed in, the death aura of the eighteenth-level Undead Overlord suppressed them again.
All the Undead within a radius of a few miles instantly stopped moving and stood still.
Yang Dingtian didn't say anything, and directly blasted the Three Profound Fire Lightning.
"Boom!"
The terrifying light of a nuclear bomb exploded once again, and hundreds of undead creatures were all turned into ashes. Suddenly, colorful Hell Magic Crystals floated in the air.
Yang Dingtian recovered his Battle Qi at the fastest speed, and then blasted again!
Three times, four times, five times, six times …
After a total of eighteen times, nearly three hours later.
Yang Dingtian finally wiped out this wave of close to two thousand undead creatures.
Then, he quickly went to collect these two thousand Hell Magic Crystals.
This time, it could be considered the biggest harvest in history.
After collecting these Hell Magic Crystals, Yang Dingtian said, "Nether Ghost Emperor, you should give me the Energy Essences of the first two waves."
After the Nether Ghost Emperor swallowed countless Hell Magic Crystals, his cultivation had skyrocketed, and he suddenly felt like his soul had left his body.
After hearing Yang Dingtian's words, he directly said, "Do you think I will be greedy for your Hell Magic Crystals?"
Then, a handful of Energy Essences quickly appeared in Yang Dingtian's palm.
Yang Dingtian quickly put them all into the energy jade box.
"Oh right, I can't purify the fourteenth-level, fifteenth-level, and sixteenth-level Hell Magic Crystals at the moment. I need to at least break through to fourteenth-level," the Nether Ghost Emperor said.
Yang Dingtian asked, "How far have you broken through?"
"Fifth-Level twelfth-level."
The Nether Ghost Emperor said, "Because I didn't devour the Hell Magic Crystals above fourteenth-level, that would be too wasteful. So, I need your Hell Magic Crystals below thirteenth-level. Quickly send them in.
After I break through, I can purify the high-level Hell Magic Crystals for you. "
Yang Dingtian immediately stuffed close to two thousand Hell Magic Crystals into the Soul Ring.
Suddenly, the Nether Ghost Emperor trembled, as if he had taken drugs.
"Heavens!
Heavens! Heavens! Heavens! Heavens! "
"This world is too crazy. Only when you lose it, do you know how precious energy is!"
Then, the Nether Ghost Emperor quickly took out his share and devoured it crazily.
Yang Dingtian began to recover his Battle Qi, preparing for the next wave of killing.
Because there was not much time left, the two moons were already in the west, and the Great Taboo Day was about to end.
…
Soon, Yang Dingtian arrived at the next wave, which was already four hundred miles away.
There were even more undead here, more than ten thousand of them.
However, their levels were too low, the highest was only ninth-level. Even tenth-level undead couldn't be seen!
This should be the outermost area of this area.
Although killing this batch of undead was relatively easy, the price-performance ratio was too low.
Thus, Yang Dingtian decided to try another undead area. If he could encounter a wave of two thousand undead of between tenth and thirteenth-level, that would be too awesome.
After making the decision, he immediately went to do it.
Yang Dingtian used the Demonic Mist Cloak's Blink Technique!
He quickly flew towards the south, looking for the next undead area.
…
This was a simple matter.
Yang Dingtian didn't care about the consumption of his Xuan Qi at all. He used the Blink Technique and rushed a thousand miles away, discovering a brand new undead area.
He directly rushed to the outermost area, where there were more than ten thousand low-level undead.
Yang Dingtian didn't rush in immediately, but sat down cross-legged to restore his combat Xuan Qi.
Originally, Yang Dingtian was worried that if he wasn't the overlord of this area, these undead would be afraid of him and rebel.
As a result, he worried too much.
When he appeared in this group of undead, the tens of thousands of undead were motionless, standing there, and all stopped killing each other.
After restoring his combat Xuan Qi.
Yang Dingtian began to go deeper.
Soon, he encountered the undead group that he had dreamed of.
This wave of undead was more wonderful than Yang Dingtian had imagined.
There were nearly three thousand undead, with the lowest being ninth-level and the highest being thirteenth-level!
The situation of this group of undead was simply perfect!
At this time, the two moons were already very far to the west, and there wasn't much time left.
This was definitely the last wave of hunting, and it was also the wave of hunting that Yang Dingtian had reaped the most rewards.
He took a deep breath.
He summoned three Xuan Flames, and then injected all his Xuan Qi energy.
The three Xuan Flames flew into the air and slammed into each other.
"Boom!"
The unparalleled Xuan Flame Lightning suddenly enveloped the whole group of three thousand undead.
Once again, there was a violent light like a nuclear bomb.
Countless low-level undead were instantly turned into ashes.
Fast, fast, fast …
Yang Dingtian took the Xuan Gathering Pill regardless of the cost to restore his combat Xuan Qi.
Then, he released the second Xuan Flame Lightning as fast as he could.
"Boom!"
In the light of the power of blinding, countless undead were instantly turned into ashes.
In this way, Yang Dingtian restored his Xuan Qi as fast as he could and released the Xuan Flame Lightning as fast as he could.
The tenth attack.
The fifteenth attack.
The twentieth attack.
The two moons were constantly slanting to the west, and the end of the Great Forbidden Day was getting closer and closer.
And around Yang Dingtian, the surviving high undead were getting fewer and fewer.
The twenty-third attack.
The twenty-fifth attack.
Soon, soon.
There were only a few high undead in the surroundings.
"Boom!" Yang Dingtian suddenly released the last Xuan Flame Lightning.
In an instant, the last few high undead were all turned into ashes.
In the air, there were three thousand Hell Magic Crystals floating.
Sure enough, it was the most abundant harvest. Yang Dingtian's hunting feast was over.
Next, it was time to count all the harvest of the Great Forbidden Day.
It was really a case of not opening for half a month, but opening for a hundred years.
