With a loud explosion, a building shattered. Countless divine lights lit up around the building. The shattered fragments struck the light screen but were intercepted without causing greater damage.
Yingbokong was trembling at the edge of the ruins. Just now, Lei Yun'er's thunderball had gone out of control. If Long Chen hadn't blocked it, he would have been blown to pieces.
"I told you, take it easy." Long Chen looked at Lei Yun'er, whose face was filled with shock, and said somewhat speechlessly.
Long Chen taught Lei Yun'er the method to control the world-ending lightning. Relying on her bloodline talent, Lei Yun'er thought she could control it completely, but in a careless move, she blew up the training room.
If it weren't for the training room and the formation supporting it, the fragments of these buildings flying out would likely cause even greater destruction.
"Alright, let's pay for it this time." Long Chen shrugged helplessly, saying that the training room was rented, but Lei Yun'er smashed it, so he probably had to pay a lot of money.
Lei Yun'er didn't care about the compensation. She looked at her own hand, still unable to recover from her shock.
"What a terrifying strike! You just used less than a tenth of my strength, yet its destructive power rivals the most powerful moves of our Thunder Falcon clan." Lei Yun'er said, both surprised and delighted.
"Don't rush to surprise yourself. You can't control it at all. With your current control, if your power reaches fifty percent, a single strike will seriously injure you; if you exceed sixty percent, you'll lose your life.
You should calmly learn how to control it; if you can't control a power, no matter how strong it is, it means nothing. Long Chen said seriously.
Because Lei Yun'er was a demon beast, her soul power was not strong. The thunder techniques she controlled were all related to her bloodline. The move Long Chen taught her had nothing to do with her bloodline divine ability.
Even though she was familiar with the power of thunder and used primordial power, controlling the World-Destroying Lightning was still quite challenging.
Sure enough, someone arrived quickly. For this training room, Lei Yun'er paid two hundred Immortal King Crystals, all out of respect for the Lei Sun clan; otherwise, it would have been even more, and they only charged one cost.
Then Lei Yun'er rented another training room. This time, Yingbo Kong stayed outside the door, politely saying he didn't want to disturb Lei Yun'er, but in reality, he was afraid Lei Yuner would slip up again and blow him up, which would be too much of a loss.
This time, Lei Yun'er was much more cautious, but her soul power was still too weak. Even though she knew how to control it, she still felt as if she were on the edge of an abyss, walking on thin ice. One wrong move and she could lose control.
Twice, she nearly repeated the same mistakes and was saved by Long Chen. Lei Yun'er was once fiery and excited, but repeated failures left her somewhat disheartened. This move was too difficult; such a terrifying move was uncontrollable, and she was almost in tears.
Long Chen comforted Lei Yun'er not to rush, and immediately refined two batches of soul-enhancing pills for her. When Lei Yun'er saw each top-grade treasure pill, she was stunned—she actually recognized the grade of the pill.
She didn't know that these two batches of pills were just made by Long Chen for Huo Ling'er and the Demon Moon Furnace. Since the Demon Moon Furnace produced demon pills, Long Chen's idea struck him: Demon pills—wouldn't it be more suitable for demon beasts to eat?
So, when Long Chen handed these top-grade pills to Lei Yun'er, she was so moved she was speechless.
She only knew that the higher the quality of the pill, the more expensive it was. She thought these treasured pills must be priceless, but she didn't know that even if these were treasured pills, they were so common that ten pills wouldn't even sell for a single Immortal King Crystal.
The demon beast clan cannot refine pills, and the Sacred Pill Hall also forbids any pills from entering the Tiandu Star Domain. Therefore, the price of pills here is astronomical.
Long Chen couldn't be bothered to explain. After Lei Yun'er took a pill, her mental power was clearly stronger than before, increasing by nearly thirty percent in an instant.
Long Chen felt a chill in his heart. It seemed demon cores really were a bit strange, and their enhancement to demon beasts was clearly stronger than that of humans. However, the immense strain on their bodies might only be able to withstand the physical strain of a demon beast.
You have to know, the demon pills Long Chen refined were basically all for his own use, because the medicinal power was terrifying and domineering, with no buffer—an ordinary body simply couldn't withstand it.
After taking it, Lei Yoon-ah felt no discomfort; the medicine worked steadily and was absorbed very well.
Perhaps because Lei Yoon-ah had never taken such a soul-type pill before, taking ten pills in a row barely diminished the medicinal effect.
After the tenth pill, the effect began to decline, and by the sixteenth pill, it was completely ineffective.
With the enhancements from these pills, Lei Yun'er's soul power increased several times over, and Long Chen used the pills to expand her soul space. With her continuous effort, there was still much room for improvement.
With powerful soul power, Lei Yoon-ah could finally barely wield the World-Destroying Lightning, instantly extracting fifty percent of her thunder power to condense a World-Destroying Thunderball. Even she herself felt fear of this move.
Even the strongest divine power of the Thunder Falcon clan could only extract one-tenth of its power to launch a single strike. That strike was already a terrifying move that made countless beasts tremble.
The new move she learned from Long Chen was already far more powerful than Lei Yun'er had imagined; she finally had her trump card.
Long Chen reminded Lei Yun'er that, due to her soul power, fifty percent of her strength was already her limit; any more would be life-threatening.
Lei Yun'er learned this move and was deeply grateful to Long Chen. She had only taught him some movement techniques, yet he had taught her such terrifying ultimate moves. She felt very guilty and wanted to teach Long Chen some other thunder attack techniques.
But Long Chen refused. What he valued most was Lei Yun'er's terrifying speed; other thunder techniques meant nothing to him.
Because his thunder power came from Lei Ling'er, his strength was not inexhaustible. With the help of movement techniques and the world-destroying thunderlight deadly technique, it was already enough.
After all, he still had the World-Destroying Fire Lotus, the Dragon Blood Battle Body, the Nine-Star Battle Body, the Nine Heaven-Opening Forms, and other moves. Power was his main theme; he had to learn to specialize rather than be greedy.
While Lei Yun'er patiently learned and mastered it, Lei Ling'er had already fully integrated her movement techniques. Lei Ling'er and Long Chen's souls were connected, and her integration was equivalent to Long Chen fully integrating them.
As Long Chen moved and moved around in the training room, thunder surged like a shower, creating countless figures with speed no less than Lei Yun'er's.
For the first time in his life, Long Chen had mastered such terrifying speed. Even if he encountered a terrifying expert in the future, he could still flee if he couldn't win. This was a life-saving ultimate technique.
Three days later, Long Chen and Lei Yun'er emerged from seclusion. Long Chen's identity badge lit up again—not only did Long Chen's badge light up, but even Lei Yun'er and Yingbo Kong's badges lit up.
"The Divine Lord Immortal Realm is about to open. We're gathering now. We'll head over now." Lei Yun'er said excitedly, and Long Chen was also filled with excitement:
"Once I ascend to Divine Lord and have the Lei Sun clan's movement skills, even if I'm a Realm King expert, I won't fear anymore."
But just as Long Chen was brimming with confidence, a string of numbers appeared on his identity tag, instantly turning his expression grim.
