My Ultimate Sign-in System Made Me Invincible - Chapter 525 Breakthrough: Fourth Stage Evolved

Chapter 525  Breakthrough: Fourth Stage Evolved

Inside the Dimensional Space, Liam sat cross-legged in the air with his eyes closed, the golden light of Yanxia’s Three-legged Crow form washing over him in slow rhythmic pulses.

The breakthrough was close. He could feel it the way you felt a storm before the first drop of rain. Everything was ready except the final push that would tip him over.

He kept his breathing steady and waited.

His mind drifted. He thought about the cultivation boost cards. The duration had run out a few days ago, which meant he had been advancing on natural speed since then but his natural cultivation speed was still faster than any cultivator, thanks to his Constitutions and how dense the Dimensional Space’s spiritual Qi had become, but natural speed nonetheless.

He had felt the difference the moment the cards expired. It wasn’t weakness exactly, but the particular sensation of moving through water after moving through air.

He thought about the sign-in.

It had been a while since he’d used it, and there was a reason for that. The rewards had always been generous  but the problem was that most of what the system gave him required a level of strength he hadn’t reached yet.

The items sat in the Dimensional Space, gathering metaphorical dust while he caught up to them. He had no interest in adding more to that pile.

So he had stopped signing in.

But today was different. Today he would sign in after the breakthrough, and what he was hoping for specifically was more temporary cultivation boost cards. A 100x boost card would be ideal. Three of them would be better. He filed the thought and set it aside for after.

Then a different question surfaced.

Could he just buy them?

The system store had always been available. He immediately opened it now and searched for cultivation boost cards.

The results populated immediately.

He stopped and his eye went wide in surprise.

He had assumed the cards capped at 100x. That was the highest he had seen and the highest he had used, but looking at the result, it was evident that the ceiling wasn’t there.

Comprehension boost cards and cultivation boost cards both, ranging from 10x all the way to 10,000x, listed in clean ascending order with their prices beside them.

He looked at the prices carefully.

The 10x boost card cost 15,000 system points. At the conversion rate of $10,000 per point, that came to $150 million — significant by any ordinary standard, barely a consideration against what Nova Technologies was generating monthly.

Liam registered it as the baseline and kept reading.

The 100x card cost 300,000 system points. $3 billion. One card. He could afford one with the cash available and he would buy it without hesitation if that was the only option on the table.

Then he reached the 1,000x card that costs six million system points, which is an equivalent of $60 billion.

The 10,000x card sat below it and it costs a staggering 120 million system points, an equivalent of $1.2 trillion.

He nodded slowly in understanding. The pattern was clear. Each step up in multiplier didn’t just cost more — it cost exponentially more, the price climbing at a rate designed to make the higher tiers feel genuinely out of reach rather than just expensive.

For most people, they would have been completely out of reach.

For Liam, the situation was more complicated.

His cash position was close to $5 billion. But beyond the cash, he held more than 100 million Purple Grade Mana Crystals, thousands to millions of gold coins across, and a very significant reserve of medium to higher-grade spirit stones that had been accumulating since the spirit Qi lake began producing them in volume.

The combined monetary value of everything, converted at system rates, came to roughly 2 million system points.

It was a number that felt large by almost any standard he could think of but it still wasn’t enough for a single 10,000x card.

He looked at the 100x cards again and made his decision. He would convert everything liquid — all the cash and half of the remaining material holdings. The gold coins, the mana crystals, the spirit stones, half of each.

The conversion completed instantly. One moment the assets existed. The next moment they were gone and he had 1,250,000 system points sitting in his system balance.

Without hesitation he purchased four 100x temporary cultivation boost cards and three 10x temporary cultivation boost cards.

5,000 system points remaining.

He looked at the seven cards in his inventory and a thought arrived that should have come earlier.

He had only activated two cards at a time before but they were of different multipliers. He had never considered whether multiple cards of the same multiplier could be activated simultaneously, whether the multiplicative stacking applied across more than one at a time, whether there was a ceiling on what that combination could produce.

He decided to ask the system.

“System. What would happen if I activated two or three 100x temporary cultivation boost cards at the same time? Would the multiplicative effect apply?”

[Yes, host. You can activate up to three temporary cultivation boost cards simultaneously. The multiplicative effect will apply across all active cards. Total boost cannot exceed 100,000x cultivation speed.]

His eyes went wide in realisation of what the system has just said. Three cards can be activated simultaneously, the multiplicative stacking will apply and it has a cap of 100,000x.

He immediately understood what it meant. One 100x and one 10x card had already changed his cultivation timeline in ways that compounded week over week.

Three cards together, multiplying against each other rather than simply adding, produced a figure that sat at the edge of what he could apply meaningful context to. And the 100,000x cap meant the system had been designed with this use in mind, and that it wasn’t an exploitation on his end.

He was going to grow stronger faster than he had thought possible even an hour ago.

Without delay, he selected one 10x card and two 100x cards and activated all three at once.

[Activating x10 Temporary Cultivation Speed Card…]

[Activating x100 Temporary Cultivation Speed Card…]

[Activating x100 Temporary Cultivation Speed Card…]

[Cards are now active. Effects will stack multiplicatively for a total boost of x100,000 cultivation speed.]

[Duration: 30 Earth days remaining.]

The effect was immediate and total.

Dark energy, mana, and spiritual Qi poured into him from every direction simultaneously.

The Dimensional Space’s atmosphere, already dense with Yanxia’s influence and the Eternal Qi Vein’s constant output, became a current he was sitting at the center of.

His Origin Devouring Body handled it without strain.

That was what the physique was built for — not just absorbing energy but refining it, taking three fundamentally different energy types running at incompatible frequencies and converting them into something unified that his cultivation base could actually use.

He felt his cultivation base fill completely and immediately. It was like a reservoir reaching capacity within a single breath and then pressing against the boundary of his current stage with a force the boundary was not built to hold.

The breakthrough happened, like a wlwall giving way, and immense amount of Primordial Essence flooded his body.

Fourth Stage Evolved.
