After the grey-brown substance is ground into powder, it has a name called Gulei powder.
In fact, it is a substance in which thunder is solidified, and the energy of thunder itself still exists in the solid thunder powder.
Yuanshi Tianzun once asked the strong men of the human race to collect the brown substances on the Tianlei Plain, and later Yuanshi Tianzun ground them all into thunder powder.
When a considerable amount of Gu Lei powder is gathered together, the power of the explosion is extremely terrifying.
In the Thirty-Third Heaven, once the human race was chased by the Heavenly Punishment Beast. The strong men of the human race also suffered heavy casualties. When their lives were hanging by a thread, Yuanshi Tianzun threw a large amount of thunder powder into the huge mouth of the Heavenly Punishment Beast.
Then, they detonated simultaneously.
The moment countless thunders bloomed, a round thunder ball was formed!
It was so powerful that even Yuanshi Tianzun himself was frightened. After all, it was several days of thunder in the Tianlei Plain that exploded together, blasting the head of the scourge beast into a bloody mess. Only then did the strong men of the human race escape.
One calamity.
Luo Zheng naturally didn't know the origin of this prison lock thunder light, but the Phantom Thunder Slave finally took form, so he naturally wouldn't let this opportunity go.
"Kakaka..."
The sections of gray-brown substance were quickly crushed into powder under the kneading of Luo Zheng's hands and scattered all over the ground...
"don't want!"
"You...can't!"
"stop!"
In the remaining section of thunder, Huanlei Nu's voice continued to roar.
Both the Kisaragi Fire Slave and the Ningbing Ice Slave have spiritual cores. When fighting with others, you need to carefully hide your spiritual core. Once your spiritual core is crushed, your life will naturally end.
However, Huanleinu do not have spiritual cores, and their special life forms are difficult to perish.
How could it have thought that Luo Zheng just had the method to kill it!
At the moment before death, Huanlei Nu was naturally very unwilling. It struggled and roared, and its voice exploded in Luo Zheng's ears like thunder.
But Luo Zhenghun acted as if he hadn't heard anything, and just released the prison lock thunder light, grinding the fantasy thunder slaves into powder one by one...
When there was only the last part of Huan Lei Nu left, it turned into a human face and begged towards Luo Zheng, but Luo Zheng did not give it any chance.
With a flash of purple light, the thunderous face turned into powder and flowed between Luo Zheng's fingers.
"This... a fantasy thunder slave was killed like this?"
Feng Nu lying on the ice had an expression of disbelief on her face.
She was once considered a subordinate of the Yuanling clan, and she also carried out exploration missions with Huanlei Slave and Ningbing Slave.
This ever-changing thunder creature had left her with very profound power. It was powerful, immortal, and extremely fast. This thing was almost a perfect combat creature...
But there was no time to hold on to a stick of incense in Luo Zheng's hands...
This kid...
Luo Zheng naturally didn't know what Feng Nu was thinking. He stared at the two ice slaves not far away with a vigilant face and asked: "What should we do now? Let's rush in directly?"
He didn't know the situation inside the ice castle. If it was unguarded like the twenty-eighth sky, he could just rush in and rush to the thirty-first sky...
Although Feng Nu was weak, her mind was still very clear. She made a decisive decision: "Come in!"
According to her judgment, the Yuanling clan will put most of their troops in the ice castles in front. The last ice castle will not be too tightly defended, not to mention that Luo Zheng has already killed a Fantasy Thunder Slave!
Luo Zheng pulled Feng Nu up from the ground and said to Li Beixue: "Come in with me!"
Li Beixue nodded, and the wings behind Feng Nu began to shine with golden light. Although she was weak, she could still use the Golden Crow Divine Fire to defend against enemies.
The two Ningbing slaves saw Luo Zheng killing the Fantasy Thunder slave, and they were also very jealous of Luo Zheng. Seeing that Luo Zheng was planning to storm the ice castle, they had to stop him.
But just when Luo Zheng was about to take a step, the ice castle suddenly shook, and waves of reddish-brown soil poured out from the ice castle!
The surging soil also brought with it strong energy fluctuations. When the soil poured out of the ice castle, it quickly transformed into human shapes. They were actually clay figures!
"Burial soil slave!"
Feng Nu said in shock.
These Burial Earth Slaves are also Five Elements Spirit Slaves. Although they move slowly, their defense power is amazing. They are harder to kill than the Phantom Thunder Slaves!
If these burial slaves were guarding the ice castle, it would be difficult to rush in...
"No matter what kind of slave he is, he can only force his way in!"
Luo Zheng gritted his teeth and rushed towards the ice castle.
But just as he was halfway out, there was a burst of blue light inside the ice castle, and snow-white figures shot out from it. They were ice slaves, probably more than a dozen in number!
With so many earth-burial slaves and ice-crystal slaves guarding the ice castle, it was almost impossible for Luo Zheng to rush in.
He stopped abruptly and his face became very ugly.
Li Beixue and Luo Zheng were able to escape from the other side, but Feng Nu was probably dead. Moreover, after leaving the other side, the Yuanling clan would probably tightly control this place. Luo Zheng should not expect to return to the other side...
"Rumble..."
There were deafening roars in the distance, and streaks of lightning were flying towards this side.
It was the Huanlei slaves in other ice castles who heard the news and were rushing over at extremely fast speeds.
You can't break into the ice castle, and there are people chasing you from behind, so there is almost no way to escape.
"Let's exit the other side first before you are contaminated by the soul-breaking sand..." Feng Nu said.
Feng Nu also knew the fate of Luo Zheng's withdrawal from the other side, but she had almost no choice but to save her life.
Luo Zheng suddenly glanced upward, and then said: "No, there is another way..."
When Feng Nu and Li Beixue heard this, they immediately reacted.
Escape back to the upper ice sheet!
The ice cave they just dug has not completely frozen yet, but has a layer of crushed ice. Now there is a full chance to rush up.
"Walk!"
The moment he made the decision, Luo Zheng grabbed Li Beixue and flew upwards with Feng Nu on his back!
The two Ningbing slaves not far away saw Luo Zheng trying to escape, how could they easily let them go?
The four wings behind him were raised fiercely, and he followed behind!
"snort!"
Feng Nu snorted coldly, her golden wings suddenly trembled, and the blazing Golden Crow Divine Fire was like a cloud of fire, covering the bottom and forcing the two Ningbing Slaves back.
"Whoosh!"
In just two or three breaths, Luo Zheng had already drilled into the ice cave. As the golden flames burst out from the ice cave, the broken ice in the ice cave had been melted by the Golden Crow Divine Fire.
Luo Zheng then drilled through the ice cap and came to the upper layer of the ice field. At the same time, Feng Nu took out the Yuanling Shenhuo, ignited it, and placed it firmly on the heads of the three people.
Luo Zheng held the Yuanling Divine Fire Shield in one hand, carried Feng Nu on his back, and dragged Li Guixue with the other hand, running wildly on the upper level of the extremely cold ice field.
