A moment later, the three sat cross-legged on the ground. Xiao Guo and Xiao Lian listened to Lu Chenxing's explanation, feeling somewhat confused, completely unable to distinguish which was which.
In their understanding, an explosion was a burst of Fire Element, or an elemental rampage after Fire Element and Lightning Element came into contact.
Since when could Water Element and Lightning Element combine to explode?
Although they didn't understand the principle, they could feel that Lu Chenxing's explanation was very detailed; even those with no foundation like them could grasp it partially.
But if what Lu Chenxing said was true, then they would likely gain an attack method that no one else could anticipate!
Yes, they considered this an attack method and didn't perceive it as dangerous.
At this moment, Lu Chenxing had finished explaining and said with a smile, "In short, that's how it is. You two need to be careful when cooperating in the future, pay attention to the usage area, and don't accidentally injure yourselves!"
Xiao Guo immediately raised her hand and said, "Boss Lu! Can you demonstrate it for us?"
Xiao Lian on the side also nodded repeatedly, extremely excited!
Seeing this, Lu Chenxing scratched his head a little. Why were these two girls reacting differently from what he expected? But then he thought that they were not ordinary female university students, but professionals who fought against Strange Beast, so it was not strange.
"Alright, you two cast a spell again. Listen to my command later. After I shout, Xiao Lian, immediately cast a Lightning Element spell, aiming it at the position diagonally above. First-tier or second-tier doesn't matter, speed is what's needed, understand?"
Xiao Lian nodded repeatedly, "Understood!"
Afterward, the two stood up again and cast their spells!
As the waterfall-like water column impacted downwards, the lightning column also fell. After the lightning column disappeared, a large amount of hydrogen was produced in that instant, rapidly forming a mixed gas cloud with the surrounding air!
At the same time, Lu Chenxing, in his Wind Element perception state, narrowed his eyes and shouted, "Now!"
As his voice rang out, Xiao Lian released another thin bolt of lightning from her hand. This wasn't a spell, but a basic application of elements, lightning formed by condensing Lightning Element.
That slender purple lightning struck towards the air diagonally above. It appeared so insignificant in front of the huge water column, even feeling like a spider web that could snap at any moment, yet all three pairs of eyes were fixed on it.
How fast is the speed of light? In an instant, it contacted the mixed gas cloud, and a flash of fire suddenly appeared and vanished in that empty space!
"Boom—!!!"
A loud bang occurred. Although the cultivation room used spatial technology and its area was not small, the three could still feel a distinct shockwave sweep through, but as Lu Chenxing said, the power was not great.
"Did you see that? Although the power isn't great, it's still very dangerous. Imagine if the entire cultivation room were filled with this explosive mixed gas right now; you within it would definitely be injured, so you really need to be careful," Lu Chenxing finally warned.
"Understood, Boss Lu, thank you," Xiao Guo thanked him politely, while Xiao Lian on the side seemed lost in thought.
"Filling the entire space..."
Having resolved their confusion, Lu Chenxing left the training ground, humming a tune as he returned to his Card Shop, and began his cultivation.
With his spiritual power already broken through, the breakthrough in magic power seemed very easy. Easily, dozens of second-tier complete crystal cores were consumed, and when the moon illuminated the night sky, his realm reached late second-tier.
Moonlight poured in through the window like mercury, and Lu Chenxing stood up, letting out a long breath, feeling incredibly refreshed.
"Phew, let's rest and make the Riding the Wind card first."
A moment later, the lights in the Card Shop lit up. Lu Chenxing came to the workbench, making cards while thinking about future matters.
He could feel that the energy required for his upgrades was getting higher and higher. The breakthrough in magic power, merely from mid-tier to late-tier, had actually consumed dozens of second-tier complete crystal cores.
At this rate, breaking through from late-tier to complete mastery, he wondered how many more crystal cores would be needed.
He knew this was because his talent cap was too high, so he needed more energy to upgrade, but for him as a second-tier, how to obtain higher-density energy was a problem.
"It seems I can only ask Guo Jiahao for help," Lu Chenxing murmured to himself.
He still clearly remembered the benefits that the wisp of "World Aura" from the world tree dewdrop had brought him at that time. Although it seemed to only enhance his spiritual realm, it also planted the seed of rules.
So from this, it could be seen that some truly good things were still of great use to him!
"The improvement of the spiritual realm probably requires something similar to the world tree dewdrop. For the improvement of magic power, I still need to inquire further." Lu Chenxing sealed the spell into the original card in his hand, watching the original card gradually glow golden, while pondering to himself.
After making up his mind, Lu Chenxing began to fully dedicate himself to making cards, completing the Riding the Wind card, and sending the procedures and everything to President Long, asking him to help process it.
As expected, professionals don't need to sleep. Not long after he sent it, various procedures were sent to his phone, along with a query: "Late second-tier?"
Looking at the message, Lu Chenxing smiled and replied, "Mm."
"If there's anything else you need, remember to tell Regimental Commander Song and have him arrange it."
"Okay."
Although Lu Chenxing said okay, he didn't intend to inquire, because what he wanted wasn't regular supplies, but something comparable to the world tree dewdrop, which he could only buy himself.
Not to mention that he hadn't found such things in the military merit store, even if he did, they wouldn't just give it away.
Although they said they would cover his promotion to third-tier supplies, if he really asked for too much, demanding everything, then there would definitely be some trouble coming his way.
However, he didn't plan to refuse regular supplies either. In fact, as long as he consumed enough, it could still allow him to successfully advance, so he still pulled a list and sent it to Song Lijie.
This list was similar to what he had asked for the first time, and they didn't say much, only that it would be delivered early the next day.
After dividing the Riding the Wind card into first-tier and second-tier cards, Lu Chenxing began to create his various elemental combination cards, for example, using light and darkness as wildcards to combine with various other elements.
As he continued to be busy, a knock on the door sounded, "Boss! I'm here for work! Are you awake?!"
