Others Level Up, but I Pursue Cultivation!

With that thought, Su Xing glanced at the sky and began to disguise himself and conceal his presence.

As the sky darkened slightly, Su Xing left the Kyoto Academy and ran out of Kyoto City.

After confirming that no one was paying attention to him, Su Xing executed the Heavenly Secrets Shielding Technique and took to Sword Flight, rushing towards Ma Yi City in the Northwestern Province.

Soon, Su Xing arrived near the location of the Red Lotus Demon Cave instance he remembered.

Approaching, Su Xing indeed found a fully armed professional army lingering outside the instance of the Red Lotus Demon Cave.

As a taboo-level instance, the Red Lotus Demon Cave was naturally under strict control.

The professional army was there not only to prevent monsters from escaping the instance but also to prevent people from accidentally wandering in.

However, the strength of these professional soldiers was only around the Master or Grandmaster Level; they did not dare get too close to the entrance of the instance.

For Su Xing, a slight application of the Eight Trigrams Fortune-Telling Technique to shield his presence from them was enough to successfully blend into the Red Lotus Demon Cave instance.

To the current Su Xing, these Grandmaster Level professionals were no different from ordinary people.

Stepping into the Red Lotus Demon Cave instance, Su Xing quickly entered a strange environment.

Clearly, this was no longer Blue Star.

"Hmm... the temperature around here has risen quite a bit, with a perceived temperature of about fifty to sixty degrees Celsius..."

Su Xing nodded slightly, but such a temperature felt like normal room temperature to him.

Even though Su Xing's strength was now comparable to that of legendary fighters, out of caution, he still put up his Protective Gang Qi and triggered his Origin Force armor.

After some exploration, Su Xing came upon a nearly vertical descent into an abyss which allowed for only one person to pass at a time.

"Here, this should be the passage that leads to the core area of the instance..."

Without hesitation, Su Xing directly flew into the cavern.

Due to the narrow structure of the cavern, he couldn't achieve his maximum speed.

As a result, Su Xing took several hours to reach the thousands of miles deep Flame Demon area.

At this moment, the surrounding temperature had soared to three to four thousand degrees Celsius, a level at which only those above the Heavenly King Level could survive.

With his Divine Sense, Su Xing quickly detected the Flame Demon he had encountered in the simulations.

There was no dallying.

Origin Force coiled around his arm, and he threw a punch!

In just an instant, the life force of the Flame Demon rapidly diminished.

A Martial Emperor peak Flame Demon couldn't withstand even a single move from Su Xing!

"This is the benefit of steady development!"

"No matter what level the enemy is... once I'm fully grown, I'll cut you all down from your horses!"

Su Xing's lips curved upward ever so slightly as he continued to explore deeper into the nest of the Flame Demon.

Before long, Su Xing found an even deeper cave leading to the magma layer.

"Down there, that should be the region where the Special Metal ores are located..."

Su Xing explored further into the depths of the cave, and soon he saw a magma pool.

By now, the temperature had reached over five thousand degrees Celsius.

Luckily, Su Xing had his Protective Gang Qi to isolate the inside from the outside, so his body was unaffected.

Thus, Su Xing's gaze passed over the magma pool, looking towards the ore region beside it.

Indeed, within the uneven rocks, there mixed in plenty of reddish special metal.

"Indeed, Special Metal ores!"

"So... it's time to get to work!"

Su Xing took a deep breath and pulled out his Spirit Sword Mo Bing.

Under the nourishment of Origin Force, the Ink Ice Sword had become even sharper and more durable.

Su Xing's heart moved, and he wrapped Origin Force around the Ink Ice Sword.

Then he chopped at the metallic rock layers that were mixed with special metals.

Under the action of Origin Force, these uneven rocks were cut as easily as tofu, leaving smooth and flat surfaces.

Su Xing, a bit obsessive-compulsive, cut every piece of ore into one cubic meter blocks.

Immediately after, Su Xing spent the entire night mining relentlessly.

Until, by noon the next day, the last of the special metal ore had been excavated by Su Xing.

Only then did he feel satisfied and prepared to leave.

"A thousand cubic meters of ore containing special metal is now in my hands... These ores are worth at least 1.5 billion energy!"

"As for whether to refine them or to absorb them directly, I'll consider it later... It's not safe to stay here for long, better leave first!"

So, it took Su Xing several more hours to leave the Red Lotus Demon Cavern instance.

Traveling by Sword Flight, he did not return to his dormitory until the evening.

Decisively entering the Spirit Field Blessed Land, Su Xing breathed a sigh of relief, but couldn't help his heart thumping wildly.

"Goodness, this is special metal worth a full 1.5 billion energy!"

Su Xing looked at the mountainous pile of special metal before him and began to ponder.

"If absorbed directly, it's only worth 1.5 billion energy..."

"But if refined, it could be worth 3 billion energy!"

"However, I expect that refining this special metal will be very time-consuming... I just don't know how much time it will actually take?"

Su Xing hesitated for a bit before making a call to Jin Congxue.

"Hey, busy person, how do you have time to call me?" Jin Congxue's voice came from the other end of the line.

Su Xing chuckled and said, "Cough cough... I have some things to ask you. Those special metals, they need to be refined and purified, right?"

Jin Congxue's affirmative reply came through the phone:

"Isn't that obvious? You're the big boss who's contracted six mining instance areas, after all! Don't you even know this much?"

"Mining is tough, but refining also takes time. The special metal you get each week probably needs to be refined four to seven days in advance..."

"Of course, the higher the grade of the special metal, the more time it needs for refining and purifying."

Hearing this, Su Xing showed an 'as expected' expression and then inquired:

"Sister Xue, if it's a thousand cubic meters of ore containing third and fourth-rank special metals, with a purity of around 3.7%... how long would it take to refine and purify?"

Jin Congxue was not expecting Su Xing to ask such a detailed question so seriously.

After pondering for a moment, she said:

"Based on your description... I estimate that purifying this batch of ore will take about a month... "

Upon hearing this, Su Xing's eyes brightened; a month's time to purify special metals worth 1.5 billion energy could yield a direct 3 billion!

Hisss~ That's quite the profit!

"However, there's a problem... If I refine it all, then I won't have any model energy for practice..."

After some hesitation, Su Xing decided to absorb one-third of the special metals first, equivalent to five hundred million model energy.

The rest would be handed over to Jin Congxue for refining.

"The remaining six hundred plus cubic meters should take about three weeks to refine... Then the 1 billion energy would directly turn into 2 billion!"
