Su Zhan quickly cupped his hands and answered a little nervously, "Lord Zhou."
It must be said that the vision of a fourth-level Mortal Realm cultivator is indeed sharp. With just one glance, Zhou Yueshan saw that Su Zhan was about to reach the second level of the Mortal Realm.
During these three days, Su Zhan had ten little blacks mining simultaneously. This allowed him to absorb four, five, or even ten spirit stones at a time to practice.
The cycle that originally took nearly a month was quickly compressed to half a month as the number of spirit stones he absorbed increased.
It was just that he was a small, unnoticed person who could only exchange one low-grade spirit stone every day, and suddenly made such rapid progress, which inevitably attracted some attention.
Almost in an instant, many reasons and excuses popped up in Su Zhan's mind.
"Okay," Zhou Yueshan said.
However, Zhou Yueshan seemed to be just asking casually and didn't want to press the issue. He directly retracted his gaze and continued to close his eyes to rest.
Su Zhan breathed a sigh of relief in his heart.
With his current comprehensive strength, he had the confidence to negotiate with second-level or even third-level Mortal Realm cultivators and escape calmly at the worst… But facing a fourth-level Mortal Realm cultivator, he had no confidence at all!
Although this was only a gap of one level, it was the first watershed of the Mortal Realm.
A fourth-level cultivator can completely crush opponents below the fourth level!
Not to mention that Zhou Yueshan was not an ordinary fourth-level Mortal Realm cultivator.
Being able to be a member of the punishment team in the mine was enough to show that the other party was a leader among the fourth level… He might even be able to fight against the fifth level of the Mortal Realm!
Naturally, the pressure brought by the other party was extraordinary.
"Second level."
"As long as I break through to the second level in a few days, then with the cooperation of ten second-level Mortal Realm Xiaohei with the same strength as me, I will be able to escape even when facing the fourth level of the Mortal Realm!"
Su Zhan thought to himself, "But to be on the safe side, I have to come to the exchange house as little as possible in the future, and it is best not to come."
It's not that he didn't trust Zhou Yueshan.
It was because the environment of the mine was too dangerous… Before he had sufficient strength, he would never expose himself to danger easily!
Of course, not going to the exchange house for a long time would inevitably attract attention.
But by the time he was discovered, he might have grown to the point where he could compete with the fourth level of the Mortal Realm!
...
In the blink of an eye, a few days passed.
It had been nearly a week since the last time the black mark was upgraded to the fifth stage.
At this time, Su Zhan was deep in the mine, sitting cross-legged in a place so dark he couldn't see his hand in front of his face.
Beside him, ten little blacks stopped mining and surrounded him completely according to Su Zhan's instructions. Once they encountered anyone who tried to approach, they would kill them without hesitation!
The reason was very simple.
Today was the day he tried to break through to the second level of the Mortal Realm.
During the breakthrough, he must not be disturbed by outsiders… To be on the safe side, he had specially asked ten little blacks to protect him.
In order to enter the second level of the Mortal Realm, Su Zhan temporarily gave up the plan to improve the black mark and devoted himself to absorbing spirit stones for cultivation… He absorbed almost as many spirit stones as he could, pushing himself to the limit.
Dongdong!
Suddenly, Su Zhan's heart was like a bell and drum, beating faster and faster. The sound of its beating went from being barely perceptible to resounding throughout the empty and lonely mine.
The accelerated heartbeat meant that the blood in Su Zhan's body was surging wildly.
His face turned red, and the temperature of his body rose. He felt as if he was in a furnace.
As the temperature continued to rise, a wave of heat quietly dissipated from Su Zhan's body.
The air was distorted by the heat.
Finally...
Huh~
A strong momentum emanated from his body, blowing away the dust and debris around him.
Su Zhan, who had been practicing for more than four hours and consumed nearly fifty low-grade spirit stones, suddenly opened his eyes at this moment!
"I've reached the second level of the Mortal Realm!"
Su Zhan's eyes flickered with excitement.
At this moment, he could clearly feel the hot blood in his body constantly reverberating and boiling in his veins.
His bones hardened.
His flesh and blood solidified.
Even his skin became extremely tight.
The most significant change was the aura vortex in his dantian, which expanded more than doubled!
"With my current strength, if I deal with Li Lichang again, I can blow his head off with one punch!"
After shaking his hand casually, Su Zhan could clearly sense the substantial increase in his own strength. "Not only him, but also the three people surnamed Gao that day. I can easily kill them all by myself without Xiao Hei's help!"
This surging power brought him infinite confidence.
At the same time, the ten Xiao Hei around Su Zhan all exuded the same aura as he did!
The ten auras combined to blow away all the dust within a few meters.
"The second level of Xiao Hei is also achieved!"
Su Zhan smiled.
If he was promoted to the second level of the Mortal Realm, his strength had at least doubled, and he had made great progress… But with ten fearless and aggressive Xiao Hei being promoted to the second level, the overall improvement was far greater than simply doubling.
In terms of combat strength, compared to before, it was probably more than four or five times higher!
Even if a master of the third level of the Mortal Realm came to cause trouble, Su Zhan had the confidence to handle him!
"With the improvement in strength, the efficiency of mining must also improve significantly, right?"
"Little Blacks, get started and try mining."
The first thing Su Zhan thought of was to let them mine and see how much faster the second level was compared to the first level.
He had heard before that the second level was much stronger in terms of strength and endurance, so the efficiency was at least twice that of the first level.
Ten little blacks, twice the efficiency, that's a daily income of 400 spirit stones!
An hour later, the results came in, and they far exceeded Su Zhan's expectations:
The delivery efficiency was nearly three times faster than before!
"Wow!"
"This time, it's a daily delivery of nearly 600 spirit stones… This time, not only did the strength explode, but the spirit stone income exploded as well!"
Su Zhan was immediately delighted, and the arc of his mouth gradually grew larger, unable to stop smiling.
Before, he was worried that as time went on, more spirit stones would be needed, and even with so many little blacks, it would be difficult to supply enough spirit stones.
But now, this worry had completely disappeared.
Not enough quantity?
Then make up for it with strength!
