My Crazy Upgrade System

Master Sky Cyan’s repeated failures turned his face a deep, ugly crimson. It was obvious he had failed to break the seal; no matter what he tried, he couldn’t open the box. This meant his reputation would be dragged through the mud, and he would be utterly humiliated here.

He had been so sure he could break it, but who would have thought it would end in failure? This was supposed to be a fifth-grade Divine Rune, yet a Divine Rune Grandmaster couldn’t break it. What in the world was going on?

More and more people began to notice the situation, suspecting that Master Sky Cyan was actually unable to break this Divine Rune.

"No way. Even Master Sky Cyan can’t break the Divine Rune on this box?"

"That doesn’t seem possible. He’s a Grandmaster! He can’t even break a fifth-grade Divine Rune?"

"Could it be that this Master Sky Cyan is a fraud? Or perhaps the Divine Rune on the box isn’t actually fifth-grade at all."

"Even if it’s not fifth-grade, someone at the Grandmaster level should be able to open it..."

Everyone shook their heads. Some felt Master Sky Cyan’s skills were simply too poor, while others believed the box was just too mysterious. But no matter how mysterious it was, a Grandmaster should be able to open it—unless the Divine Rune on this box was of the Creation Level!

That was clearly impossible. Creation Level Divine Runes were the stuff of legends; no one had ever actually seen one. In fact, no one had even seen anything at the Creator level.

That level was far too difficult to achieve. Reaching the late stage of a Divine Rune Grandmaster was already a terrifying feat.

"What, can’t open it? If you can’t, then it’s the next person’s turn. Don’t try to tough it out," Shopkeeper Ye said, looking at Master Sky Cyan with a nonchalant expression, as if he had already predicted that the man would be unable to open it.

"Who—who said I can’t open it? I just... I just need a little more time!" Master Sky Cyan insisted, trying to buy more time to figure out how to break the Divine Rune. He really didn’t want to be humiliated.

"Fine. I’ll give you a little more time. The longer you drag this out, the more you’ll just embarrass yourself." Shopkeeper Ye went back to sipping his fragrant tea, completely ignoring him.

Master Sky Cyan mustered all his strength and resumed his frantic attempts to break the seal, but it was no use. He still couldn’t do it.

Beside them, Yang Zhiwen and his companions immediately started laughing. "So arrogant a moment ago, and now he can’t even open it? Hey, kid, what were you saying before? That your master would definitely succeed? How about now?"

"I... I... My master will definitely succeed! It just takes time! So many people failed to open it, so of course even my master has to put in more effort. As long as he breaks it in the end, what’s a little extra time!" The youth said stubbornly, refusing to back down.

"Is that so? Then you’d better hurry up. It’s almost dark. Don’t hold up our journey!" Yang Zhiwen and his group snorted, then turned to Yi Tianyun. "Boss, won’t waiting here delay your trip? We can just wait for you here in Guangyun City."

"No need to rush. We have plenty of time." Of course, Yi Tianyun wasn’t worried. ’I’m already in the Netherworld, anyway. Now there’s a quest I can complete, so why not?’

’Besides, I don’t need to wait much longer. It’ll be my turn soon enough.’

Two hours passed, then several more, yet Master Sky Cyan still hadn’t broken the Divine Rune. At this rate, it seemed he would never succeed.

Master Sky Cyan finally stood up and announced in a somber tone, "This box is not protected by an ordinary fifth-grade Divine Rune. So far, basically no one has been able to open it. Even if other Grandmasters were to try, they would not find it easy!"

He was finally admitting he couldn’t open it. The crowd burst into an uproar. To think that even someone at the Grandmaster level couldn’t break this Divine Rune—it was simply too bizarre.

"Next," Shopkeeper Ye said, waving his hand to dismiss Master Sky Cyan.

"Hmph!"

Master Sky Cyan flung his sleeve and, as he turned away, said coldly to the Divine Rune Masters behind him, "This is not something any of you can break. It would require someone approaching the Creator level to even have a chance of opening it!"

"That’s right! If my master couldn’t open it, then you lot certainly can’t! Disperse, now!" the youth added, also waving his hand to dismiss the line of waiting Divine Rune Masters.

Yi Tianyun turned a deaf ear to them, stepping forward to the box and preparing to examine it.

As he crouched down, he immediately activated his Celestial Eye to probe every detail on the box’s surface. After a careful inspection, he found that there were virtually no flaws!

While it was indeed a fifth-grade Divine Rune, its components were interlinked, forming a dead knot that was impossible to untie. If any of its parts were isolated, they would be riddled with flaws and easy to break.

But because they were interlinked, they compensated for each other’s weaknesses, making this fifth-grade Divine Rune incredibly complex and leaving almost no vulnerabilities to exploit.

’But if it can be engraved, there must be a way to break it!’

’Interlinked, are they? In that case, I’ll just destroy the balance and forcibly carve a new loophole!’ Yi Tianyun took out his Spirit-controlling Pen. He didn’t have a more advanced Divine Rune Pen on him, so he had to make do with an older one. He prepared to engrave a Divine Rune onto the box.

"You there! Are you deaf? Do you really think you can open it?" the youth sneered, thinking Yi Tianyun was ridiculously overconfident for even trying.

Master Sky Cyan waved his hand dismissively. "Some people have to learn the hard way that there is always someone better, a sky beyond the sky..."

"Enough of your nonsense. Just because you couldn’t open it doesn’t mean no one else can. If you’re done, then get out of the way. Don’t stand here holding things up," Shopkeeper Ye said, glaring at him coldly. ’This guy is just obstructing my business.’

"You..." Master Sky Cyan stared at Shopkeeper Ye, enraged. "I’m just trying to keep them from wasting their time! There’s no point in letting this continue! If any of them can break open this box, I’ll start walking backward for the rest of my life!"

"Silence!" Shopkeeper Ye grunted, and a terrifying pressure washed over Master Sky Cyan, forcing him back several steps. It was the aura of the Spirit King Stage, and it instantly silenced him; he didn’t dare utter another half a word.

Shopkeeper Ye stared intently at Yi Tianyun, and everyone else followed his gaze. They were shocked to see Yi Tianyun engraving a Divine Rune onto the box! Everyone was stunned. All the others had tried to break the existing runes; not a single person had tried to engrave a new one on top.

’But even if he engraves a Divine Rune, what’s the point?’

"Is he engraving a Divine Rune? Is this some kind of joke?"

"Everyone else came to break the runes, but he’s here to engrave one... Pfft! Doesn’t he know it’s impossible to engrave a Divine Rune on top of another one?"

"Whatever. The kid’s just bored and looking for a spectacle. Let him do what he wants."

The Divine Rune Masters in the back all started to laugh, including Master Sky Cyan. They all thought this was the most foolish Divine Rune Master they had ever seen.

Just as everyone assumed Yi Tianyun was fooling around, a sharp "DING!" rang out. A Divine Rune had actually been engraved onto the box. As it appeared, the crowd stared blankly. Before they could even react, Yi Tianyun reached out and slammed his palm onto the box.

With a loud "BANG!", the Divine Rune he had just engraved exploded. Immediately, the other Divine Runes seemed to trigger a chain reaction, exploding one after another. In the space of a few breaths, every single Divine Rune covering the box vanished completely!

"DING! Successfully broke the fifth-grade interlocking Divine Rune chain. Gained 2,000,000 experience and 2,000 Skill Level."
