My Crazy Upgrade System

Yi Tianyun watched as the black mist swirled in, sealing the area around him airtight. To escape, he would have to be able to fly; otherwise, there was simply no way out of here.

But he wasn’t the least bit panicked. He shouldered the Chaotic Celestial Saint Axe, aimed at the encroaching black mist, and swung down viciously. A frenzied arc of blade light slashed forward, carving a deep fissure into the ground. The tyrannical energy cleaved the surrounding black mist in two, tearing open a gap.

"Is this all?" Yi Tianyun’s expression was nonchalant; he was completely unconcerned.

Black Soul Ancestor’s pupils constricted. He stared at the giant axe in Yi Tianyun’s hand and said, "Is that a Soul Artifact?"

"What if it is, and what if it isn’t?" Yi Tianyun said with a faint smile. "Is that important?"

"It seems you’ve chosen to disobey me?" With a light wave of his hand, Black Soul Ancestor instantly sealed the gap. In the blink of an eye, the black energy, seemingly endless, was whole again, impossible to completely dispel.

"What do you think?" Yi Tianyun put away the Chaotic Celestial Saint Axe, and the set’s effect vanished instantly. In its place, however, was the Frost Fist. The azure gauntlets materialized on his hands, and a bone-chilling aura immediately coated the ground within a two-meter radius around him with a layer of frost.

This Soul Artifact was significantly stronger than the Chaotic Celestial Saint Axe. However, the Frost Fist didn’t have a set effect. If it did, its power would be even more heaven-defying.

"Another Soul Artifact. It seems your background is quite extraordinary, but if you think that makes you invincible here, you are far too naive!" Black Soul Ancestor formed a series of Hand Seals. The surrounding black energy morphed into countless black dragons, erupting from the ground and growing larger as their power surged. "In that case, you shall become a sacrifice for the Black Dragon Spiritual Vein!"

The next moment, under his control, the black energy rapidly formed several black dragons that lunged toward Yi Tianyun. An immensely oppressive power crashed down!

A glint flashed in Yi Tianyun’s eyes. He swiftly raised his hand, and a terrifying suction force instantly erupted from his palm. The Black Dragon Energy lunging at him from all directions was forcibly redirected by this incredible pull, coalescing into a single mass and being absorbed into his body!

’Gained 4,000 Experience!’

Just like that, the attack was absorbed into his body and converted into Experience Value. Under the immense pull of the Star Absorption Technique, combined with the North Nether Divine Technique, he instantly devoured the power. Previously, he wouldn’t have been able to accomplish this. Only after upgrading the technique to an Earth Level Martial Art could he achieve such an effect.

"Is this the extent of your power?" Yi Tianyun said with a faint smile.

’Although that attack wasn’t my strongest, I used at least half my power! Yet it didn’t harm Yi Tianyun in the slightest. It seems it was even absorbed!’ Black Soul Ancestor was inwardly shaken.

"It seems you also know an Evil Technique. I’d like to see just how much you can devour!"

Black Soul Ancestor roared, and a dozen or so streams of Black Dragon Energy erupted from the surroundings. After writhing in the air, they lunged at Yi Tianyun. At the same time, countless wisps of black mist emerged from the ground and began to coil around him like demonic hands clawing their way up from hell, frantically trying to ensnare him.

Yi Tianyun’s expression remained indifferent, paying no mind to the coiling Black Dragon Energy, as if nothing was happening at all.

"Star Absorption Technique!"

’Activate Mad Experience Mode!’

As the Black Dragon Energy coiled around him, he immediately unleashed the Star Absorption Technique. In an instant, the power wrapping around him was devoured and converted into a massive amount of Experience Value.

’Gained 16,000 Experience! Gained 15,000 Experience! Gained 21,000 Experience...’

With the four-fold experience boost, the numbers skyrocketed. ’Now this is the feeling I was looking for,’ Yi Tianyun thought with satisfaction. ’It’s so much faster than insta-killing enemies, at least for now.’

In the blink of an eye, the coiling Black Dragon Energy vanished completely, leaving Yi Tianyun entirely unharmed. From a distance, Black Soul Ancestor watched, utterly dumbfounded. He was stunned by the scene. ’All the energy I released was devoured? And he looks completely unscathed?’

"A bit too weak. Can you make it any stronger? This isn’t even an appetizer," Yi Tianyun taunted.

These words were a clear provocation, and they instantly enraged Black Soul Ancestor.

"I refuse to believe you can devour that much! Black Dragon Power is not so easily consumed!" Black Soul Ancestor roared furiously, rapidly forming Hand Seals. Countless streams of Black Dragon Power coiled around Yi Tianyun, and the surrounding black cage began to contract, threatening to crush him flat.

In an instant, Yi Tianyun was completely engulfed by the Black Dragon Power, leaving only a sphere of black light. But after just a moment, that sphere began to dim. Yi Tianyun was undoubtedly devouring the energy from within, causing the surging Black Dragon Power to grow weaker and weaker.

"Impossible... Impossible!" Black Soul Ancestor raged. "I want to see just how much you can possibly devour!"

With a furious roar, he unleashed even more Black Dragon Power. An increasing amount of it surged from deep underground, causing the entire Treasure Dragon Stronghold to tremble. It seemed that drawing on so much of the subterranean energy was triggering an earthquake!

’Gained 23,000 Experience! Gained 32,000 Experience! Gained 32,000 Experience!’

His Experience Value skyrocketed, instantly hitting its limit. That was his current cap: he could only absorb about eight thousand experience per tick, which, with the four-fold multiplier, came to thirty-two thousand. Under this frenzied absorption, his experience continued to climb steadily.

However, his absorption speed could no longer quite keep up with the rate at which the Black Dragon Power was corroding him. Black Soul Ancestor had unleashed the majority of his strength, so it was natural that it would overwhelm Yi Tianyun’s capacity. But this corrosive effect was completely useless. Dressed in the Chaotic Heaven Divine Armor and Chaotic Heaven Battle Boots, in addition to his Guardian title, his Defense Power was off the charts. An attack of this level couldn’t even scratch him.

As this stalemate continued, Yi Tianyun remained outwardly calm, but inwardly he was ecstatic. ’The experience is just pouring in! This is even more than what I’d get for killing a seventh or eighth-level Core Formation Stage expert.’ How could he not be thrilled? This had always been his most efficient method for gaining experience; the only problem was that when there were too many enemies, it was impossible to drain all of their Spiritual Power one by one.

So when he saw this massive pool of energy, his eyes had lit up. How could he not be happy about a free delivery of experience?

Just as he thought this wonderful situation could continue indefinitely, a black gleam suddenly flashed, appearing from behind and stabbing viciously at his back. Yi Tianyun immediately sensed the danger, spun around, and reached out to grab it.

CLANG!

He caught a longsword in his bare hand, the force knocking him back several dozen steps. The one who had launched the sneak attack was none other than Black Soul Ancestor himself. It seemed he had finally lost his patience and decided to attack in person.
