Guo Jiahao looked so serious that Lu Chenxing thought he was going to say something important, but he just asked that question.
Although the question itself wasn't particularly serious, Lu Chenxing thought for a moment before answering earnestly, "My refusal to be your master isn't about whether you have money or not; it's because I can't teach you anything."
"Someone teaches you how to cultivate, and someone provides you with cultivation resources. In these two aspects, I can neither teach nor give you anything."
"Before, your mother said she wanted you to learn how to conduct yourself in society and make cards from me, but honestly, I can't teach you much about conducting yourself. Your family has a large business, and they naturally have their own methods of interacting with people, so you don't need me to teach you."
"Everyone's way of conducting themselves is different. I can't teach you, and you don't need to learn from me."
"Finally, there's card making. What I can teach you in this area is also limited. Your talent and basic skills are excellent, and you've already systematically learned some card-making techniques. If you come here, all I can offer you is my unique card-making method; there's nothing else I can teach you."
"So why do you think I should take you as a disciple? Being a shop assistant is just right."
Lu Chenxing truly spoke his mind with these words; they weren't just casual platitudes. He genuinely felt that a master should act like one, not just have a title without teaching or managing anything.
If you don't need to teach or manage anything, what's the point of being a master?
The current situation was essentially like Lu Chenxing's shop being a kindergarten, and Guo Jiahao's mother paid tuition, entrusting Lu Chenxing to let him play.
In this situation, Lu Chenxing was even less likely to accept the title of master, lest he be accused of having ulterior motives or something similar.
Upon hearing this, Guo Jiahao immediately said, "I don't think there's anything wrong! If you can teach me knowledge in a certain area, can't you be my master?"
"The problem is..." Lu Chenxing said with a smile, spreading his hands, "What have I taught you?"
At this question, Guo Jiahao paused slightly, then scratched his head. After thinking carefully for a moment, he realized Lu Chenxing hadn't really taught him anything, but he still stubbornly said, "Boss, didn't you teach me your unique card?"
"Even if this shop assistant wasn't you, I would still give it, because this is inherently a benefit of joining the Card Shop."
After this exchange, Guo Jiahao was left a bit silent.
......
At this moment, in the secret realm, Xiao Guo concealed her figure. The group looked at the nearly vertical cave entrance in front of them, and the many snake-like exotic beasts coiled within, then quietly retreated.
"Xiao Lian, do we really have to do this? Will it really work? Or should we just leave! There are so many second-tier Blue-Scaled Snakes down there; if something goes wrong, we might be exhausted to death," Xiao Guo said with concern.
Xiao Lian, however, said confidently, "I completely understand what Boss Lu meant! Don't worry! Didn't he say it back then? Although that thing called hydrogen doesn't have enough explosive power, as long as the container is filled, the power is still not to be underestimated!"
"Ah?" Xiao Guo was a bit dumbfounded. Although she was tempted to use that as an attack method at the time, she gave up after seeing its actual power. "Boss Lu didn't mean that, did he?"
"Oh, well, Boss Lu said so anyway, we'll know if we try! Besides, don't we still have the card customized from Boss Lu?" Xiao Lian pulled out a card and shook it with a smile.
This was a card they had Lu Chenxing customize yesterday, named "Gold Element Supplementer"!
It contained gold element magic. After use, it would form a circular magic array in mid-air, which could continuously replenish gold elements to any spells passing through it, strengthening them regardless of what kind of spell it was!
Apparently, this card was prepared for their fusion skill, and only from Lu Chenxing could they buy such a non-offensive but specially purposed card.
"This... Alright, then let's try!" After a moment of hesitation, Xiao Guo still agreed, because even if they didn't successfully detonate the hydrogen, the power of their combined attack was still considerable!
They had tried it yesterday, and their combined strength could fully reach the standard of a third-tier early stage, meaning that even if they failed later, at least escaping would be no problem.
"If it really doesn't work, we'll just use 'Riding the Wind' that we bought from Boss Lu. Don't worry, safety is absolutely guaranteed. If this succeeds, we can not only get the materials but also make a fortune!" Xiao Lian said excitedly.
The two people behind them exchanged glances. Although they didn't know what the two in front were saying, it was clear that they were preparing to act!
Xiao Guo was not the indecisive type. Once she made up her mind, she no longer hesitated. "I'll cast the spell!"
A moment later, above the vertically downward cave entrance, a golden ring appeared, with speckles of particle-like gold elements gathering towards the center of the ring!
The next moment, a blue magic array appeared above the golden ring. The surrounding water elements rapidly gathered with Xiao Guo's chanting, "Heavenly River descends to the mortal world, thunder drums shake a thousand ravines!—Great Waterfall Art!"
A thick pillar of pure blue water surged out from the magic array, passing directly through the center of the golden ring. The water flow was tinged with a golden luster as it rushed downwards.
The Blue-Scaled Snakes below, affected by the sudden attack from above, began to stir, but were instantly submerged by the water pillar!
This cave wasn't particularly large, only slightly larger than Lu Chenxing's previous Screaming Bat cave. Now, being drenched by the surging waterfall, water flowed freely within it, rapidly submerging the entire cave!
A moment later, seeing that it was almost done, Xiao Lian's body crackled with purple electric arcs, and she shouted, "Majestic heavenly might, thunder shakes the nine heavens! Yinghuo as guide, Purple Pole pierces the void!—Heavenly Thunder Strike!"
A pillar of lightning struck down along the water flow. This time, the lightning merged into the water flow without any obstruction. Purple electric arcs freely leaped within it, causing all the Blue-Scaled Snakes in the water to stiffen instantly!
Looking at the still surging river water, Xiao Lian gritted her teeth again and said, "Strike again!"
Another pillar of lightning crashed down!
"Strike again!!!"
The third pillar of lightning crashed down, but this time, along with the shimmering purple lightning, there was also a mysteriously appearing flash of fire!
Xiao Lian's face was pale from continuously releasing powerful spells three times, but at this moment, she was quick-witted and instantly tackled Xiao Guo to the ground!
"Boom—!!!"
The next moment, the earth roared, and the intense vibrations made Xiao Lian and Xiao Guo tremble. The water that had not yet flowed into the cave entrance was blasted into the sky, turning into fine rain that fell!
When ordinary explosives detonate, they can produce 1000 times their volume in gas. Hydrogen explosions naturally cannot achieve this effect.
According to calculations from the gas equation and the equal mass, equal pressure expansion equation, hydrogen mixed with air can only achieve a 9.91 times expansion volume.
However, with the entire cave filled with hydrogen, the gas instantly expanding nearly ten times, the power was still terrifying! In short, it was much, much more powerful than a second-tier fire mage's "Great Fireball Art"!
The so-called quantitative change leading to qualitative change is precisely this.
A moment later, Xiao Lian stood up shakily, her legs feeling a bit weak, and said with a wry smile, "Boss Lu really thinks highly of us; he only said we'd be injured if we were in it. I think whether we'd even survive is still an unknown."
As second-tier professionals, they weren't body cultivators, so their physical quality wasn't particularly strong. Under such an explosion, they would probably be severely injured even if they didn't die.
