Subsequently, Lin Yun fought the robot several more times, and each time he was badly beaten, which greatly damaged Lin Yun's confidence.

"This robot was definitely the right purchase. The difference in quality is something that quantity alone cannot make up for. Now, even if I encounter a Grandmaster-level expert, I won't be powerless to resist..."

Lin Yun thought to himself.

After purchasing the robot, Lin Yun was left with only eight hundred spirit crystals.

Lin Yun then spent another hundred spirit crystals to replace his protective gear.

His battle with the robot just now made him realize that it was time to replace his protective gear.

Thus, Lin Yun was left with only seven hundred spirit crystals.

After thinking for a moment, Lin Yun spent another 500 spirit crystals to raise his spirit power level by one level, reaching level two.

Originally, he planned to wait until tomorrow or the day after to get promoted.

Because a week has passed since the incident at the Diba Club.

Since neither the Lu family nor the Mo family has come looking for him this past week, he doesn't mind leaving things as they are for the time being.

He only had ten days to hypnotize those people at the Diba Club. If he wanted to continue like this, he would have to hypnotize them again.

However, if you want to hypnotize the same thing again, level one mental strength and level one hypnosis are not enough.

His mental strength and hypnosis skills must be upgraded to level two.

It only takes five hundred mental crystals to raise your mental strength to level two.

To upgrade hypnosis to level two, one thousand spirit crystals are required.

He currently only has seven hundred spirit crystals, which is clearly not enough for simultaneous upgrades. Therefore, he planned to upgrade tomorrow or the day after. However, after thinking about it, he realized that it would be better to upgrade sooner rather than later, so that he could experience what it felt like to be at the second level of spirit power sooner.

The remaining two hundred spirit crystals should be enough for his backup.

What's more, he's acquiring spiritual crystals at such a rapid pace.

"Boom!"

Lin Yun closed his eyes and selected to purchase. Soon, a massive amount of spiritual energy entered his mind space, quickly merging into his spiritual power and making it rapidly stronger.

A few minutes later, Lin Yun's mental power suddenly underwent a transformative improvement, opening up new pathways, and his mental power began to operate along these new pathways.

Lin Yun opened his eyes and immediately felt that the world was clearer.

"So this is level two mental power... How amazing!"

A sharp glint flashed in Lin Yun's starry eyes.

He had more energy, reacted faster, and had a better memory. He even felt that the energy within his body was becoming stronger, showing signs of transforming into internal strength. The benefits were quite obvious...

The upgrade from Level 1 to Level 2 mental strength is a tremendous transformation, and the cost of five hundred mental crystals is not small. It is understandable that he could undergo such a significant change.

However, Lin Yun obtained five hundred spirit crystals very easily, so at this moment, he felt that spending those five hundred spirit crystals was well worth it.

If he had enough spiritual crystals, he would have liked to continue raising his spiritual power to level three.

Unfortunately, if he wants to improve further, he will need to spend five thousand spirit crystals.

Five thousand spirit crystals is no small amount; he currently has far fewer than that.

"According to the data on the Cosmic Trading System, Level 1 mental power can influence Ming Jin martial artists... Level 2 mental power can influence An Jin martial artists... Level 3 mental power can influence Hua Jin martial artists..."

Lin Yun said softly.

Without mental power skills, he could only have a rough influence, but that was still quite significant.

For example, if two martial artists of the same level are fighting and their strength is similar, and he suddenly releases his mental energy to affect one of them, causing that person's mental energy to become momentarily distracted, or making it impossible for them to concentrate and use their full strength, then the outcome is obvious.

In a battle between experts, one wrong step can lead to a series of defeats, and a single oversight can be fatal.

If he learns mental skills, his mental abilities will be even greater.

Level 2 hypnosis allows him to hypnotize martial artists with internal energy.

Level 3 hypnosis allows him to hypnotize martial artists who have reached the Transformation Realm.

Sometimes, it can play a big role, just like last time.

However, he was very lucky to be able to hypnotize those people so easily last time.

Different levels of mental strength are also graded, such as first-level lower grade, first-level middle grade, first-level upper grade, and first-level peak grade.

It can affect martial artists at the early, middle, late, and peak stages of Ming Jin respectively.

Last time, before he upgraded his mental strength level, his mental strength had already reached a very high level before level one. After he spent fifty mental crystals to upgrade his mental strength, his mental strength reached the upper level of level one in one fell swoop.

At that time, the strongest among those people was only at the mid-stage of Ming Jin.

In addition, the hypnosis technique he learned was indeed extraordinary. He also took a pill to stimulate his mental power and was in his best condition at the time, which is why he was able to successfully hypnotize those people in one fell swoop.

With a large number of people, the difficulty also increases accordingly. It is truly remarkable that he managed to hypnotize so many people in one go.

This time, he spent five hundred spirit crystals, and his spiritual power only increased to the lower level of the second rank. Although it was very close to the middle level of the second rank, it was not quite there yet.

It's a real shame, but understandable.

He had accumulated a great deal of spiritual power, and his spiritual power was even greater than that of an ordinary level one spiritual power user. He was just one opportunity away from transforming, and it took him fifty spiritual crystals to break through to the upper level one in one go.

The improvement from Level 1 to Level 2 mental strength is not only a qualitative improvement, but also a quantitative improvement.

As far as he knew, under normal circumstances, if he wanted to upgrade his level 2 lower-grade mental power to level 2 middle-grade mental power through the official Cosmic Trading System, he would need to spend a thousand mental crystals.

He spent five hundred spirit crystals. The amount of spirit energy provided by the official Cosmic Trading System is limited, so it's understandable that it only allowed him to advance to the lower level of the second tier.

Level 2, lower grade... Under normal circumstances... it can only affect martial artists at the initial stage of Dark Force, and those at earlier stages!

It's not that martial artists at a higher level can't be influenced, but the influence is very weak!

"A spiritual crystallization... still a spiritual crystallization..."

Lin Yun took a deep breath.

This thing is still lacking. The Cosmic Trading System is a bottomless pit that can never be filled. However, for every Spirit Crystal he pays out, he can gain more benefits.

The strongest of those people was only at the mid-stage of Ming Jin, with a second-level lower-grade mental strength, plus a second-level hypnosis technique, which was enough for their purposes.

Fortunately, hypnosis is only divided into three levels, with no distinction between lower, middle, and upper grades; otherwise, he would have been speechless.

Now, he only needs to raise his mental strength level to influence higher-level martial artists, and even hypnotize them.

Of course, it will take him a couple of days to master Level 2 hypnosis.

Currently, with his second-level lower-grade mental strength and first-level hypnosis, he can only hypnotize martial artists below the level of internal energy.
