Traveling across the globe for the first time

At this time, the crystal was purified again by the brain core, so the mental power that could be improved was even less.

Although the brain core is removing impurities, some of its energy will definitely evaporate.

After all, the brain core is not a professional purifier, so some losses are inevitable.

As the brain core continued to rotate, brilliant rays of light shone through, and in the liquid formed by the crystallization of mental power, the gray substance was evaporated and gradually turned into pure silver.

This time the brain core no longer felt disgusted and absorbed it in a flash.

A cool feeling suddenly came through Zhang Haoran's mind, and the mental power in his sea of ​​consciousness began to grow rapidly.

At this time, the Immortal Sword Soul trembled slightly, and a sword intent began to sweep through the sea of ​​consciousness, tempering the new mental power.

But this time it was just a simple tempering and then stopped.

Because the quality of the energy absorbed this time is very high, the increased mental strength is not superficial and does not require excessive tempering.

After Zhang Haoran's sea of ​​consciousness had completely stabilized, he checked his mental strength.

Sure enough, this time it only increased by 20 Hz. Although the spiritual power crystal is a very pure thing, there are still some impurities in it. After being purified by the brain core, it lost % of its energy.

The newly added mental power was very strong and did not need to be condensed or compressed. It was quickly assimilated into his original mental power.

"Right!"

When used by others, this treasure could increase their mental power by 2,000 Hz, but when it came to him, it only increased it by 800 Hz. It would be unreasonable if the strength was not much higher.

Just 12,800 Hz is definitely not enough, he needs more mental power.

Zhang Haoran took out another crystal and threw it onto the brain core to continue absorbing it.

The effect this time is similar to the previous one, and it also increased by 800 Hz.

This made him very satisfied. As expected, there was no such thing as drug resistance when it was absorbed directly through the brain core. As long as you had enough treasures, you could keep improving.

I wonder how the third one works?

After all, his mental strength is already very high now.

After absorbing the second crystal, Zhang Haoran's mental power has reached 13,600 Hz!

These two spiritual power crystals were dropped by two old men stationed in the treasure house. Their strengths were not much different, and the effects of the crystals they dropped were also similar.

He knew that the second one could increase his mental power by 800 Hz, but that was because the first one did not increase it much, and it might not be so easy to increase it further.

Zhang Haoran took out the crystal dropped by the great elder and let the brain core absorb it. Sure enough, the increase in mental power this time was less than 800 Hz, but about 760 Hz.

This doesn't mean that the Great Elder is not powerful, but as his mental strength increases, the effect of crystals of the same quality has begun to decline.

He didn't care about the few dozen hertz of mental power he was missing. He could just walk around the origin path or temper his brain core, and that would increase more than that.

What he is worried about is that he will not be able to achieve his intended goals.

"Hey! I hope I can reach 20,000 Hertz after absorbing the rest of the treasure!"

Mental strength reaching 20,000 hertz is the symbol of the Emperor, and it is also a very important dividing point.

When the burst of Qi and blood is more than twice that of the enemy, it can crush them, and the same goes for mental power.

The spiritual power of a peak saint is 30,000 hertz, so an emperor with relatively strong strength can hold out against a saint, but the same may not be true for the strongest ones, who may be killed instantly.

Zhang Haoran's mental strength has been tempered by the sword intent, and its strength is much higher than that of ordinary warriors. As long as the difference is not too big, there will be no problem.

If he could raise it to 20,000 Hz, he would not be killed instantly unless a top-level Six-Breaking Heavenly King intervened.

Now that he saw that the effect of absorbing these crystals was beginning to decline, he became a little unconfident.

If he could take back all three clones and combine them with the rare treasures in his hands, he could be sure that his mental power would definitely reach 2 Hz!

Now that the brain core is so picky, it’s hard to say.

In order to improve his strength, he cannot take back his clone, as that would be like drinking poison to quench thirst.

Zhang Haoran felt his own condition and found that the increased mental power was still under his control.

He had previously created three shadow clones, which lowered his mental limit by more than 3,000 Hz. Now he has only made up for most of it, and it is impossible for him to get out of control.

He observed the brain core again. It was still as smooth and bright as before. He did not feel any discomfort at all. Instead, it gave him a feeling of hunger and thirst.

In other words, continuous improvement will not cause any adverse consequences.

"Then continue!"

"How does the saying go?

If you can't die, then work yourself to death!

Zhang Tao's spiritual power has overflowed before, but he didn't suffer any damage. I have the Immortal Sword Soul, and I have always had a high level of control over my own power, so there shouldn't be any problems!"

Once you have made up your mind, keep improving!

Zhang Haoran flipped his hand and took out another crystal. This crystal was larger than the previous three and of higher quality.

This is the crystallization of spiritual power dropped by the True Immortal Huang Yun after his death. He was also the first supreme being to die at his hands, so it is very commemorative.

He just finished it for a while and then threw it to the core of his brain.

This time the brain core rotated faster, and rays of light shone through the brain core, beginning to purify the silver-gray liquid.

Fortunately, there was not much gray mist this time. It was obvious that Immortal Huang Yun's mental power was purer and stronger. In the end, only 10% of the energy was evaporated, and the rest was absorbed by the brain core.

Immortal Huang Yun is indeed the strongest person in the spiritual refining lineage. The spiritual power crystal that exploded after his death has a very good effect!

This time, the mental power increased by more than 1,200 hertz.

If a crystal of this quality were used by an ordinary top-level expert, it would probably increase the mental power by 3,000 Hz, which would definitely be a huge improvement.

The treasures in Zhang Haoran's hands have not been used up, so he can continue to upgrade.

He also has the spiritual power crystallization of an emperor-level strongman that he obtained after surviving a near-death battle in the King's Battle Ground.

That was also the legacy of a powerful figure from the Spirit Refining lineage who passed away. It had always been a treasure he had kept in his heart, and now it was time to use it.

Because a long time had passed since the other party's death, the energy had dissipated a lot, and this spiritual power crystal was only at the peak of a true god.

Although judging from the energy contained, it is indeed the pinnacle of True God, but its essence is still the mental power of an emperor-level strongman.

In addition, he also had two energy fruits given by Zhang Tao, both of which were top-grade treasures that could increase mental power.

Now Zhang Haoran was a little hesitant, should he take the energy fruit first or use the spiritual power crystal first?

His current mental power has reached 15,600 Hertz. No matter which treasure he uses first to increase it, the effect of the other treasure will inevitably decrease.

The higher the mental strength, the more difficult it is to improve it through external objects. This is common sense.

Therefore, he has never really tempered his brain core. He will wait until external objects are no longer effective, and then temper his brain core, so that he can maximize the benefits.

What Zhang Haoran is struggling with now is how to avoid waste.

He was certain that the spiritual power crystallization of the peak of the True God could definitely improve the spiritual power a lot. It was hard to say how much effect these two energy fruits would have at that time.

Both of these are emperor-level energy fruits, exuding the unique Taoist charm of the emperor.

He looked at the three treasures in the storage space and said with some confusion: “I don’t know if this is an ordinary energy fruit or a unique fruit.

If it is the only fruit, then there is nothing to say. It will definitely be eaten last. The demon plant can only produce one energy fruit in its lifetime, and each one has very special effects.

Even if the mental power reaches 2 Hz, the effect will not decrease much.

Ordinary energy fruits will not work. Not only will they not have any special effects, but eating too much will also cause drug resistance.

Furthermore, the efficiency of directly absorbing energy fruit with the brain core is also very low."

!!!

Zhang Haoran did not choose to ask Zhang Tao. Although this energy fruit was given by Zhang Tao, he certainly did not know it. It should be a trophy obtained from the storage ring of the Nameless Emperor or the Tai'an Emperor.

He decided to ask Wanjie Tower. He had few opportunities to use external objects to enhance his mental strength. This might be the last time, so he had to maximize the benefits.

Fortunately, it was just a simple question and did not require a detailed explanation. The fees of Wanjie Building were not high, only a basic fee of 100,000 value points.

Zhang Haoran felt a little depressed when he saw the system's deduction prompt. As his strength increased to the fourth level, no matter what he wanted to do through the Wanjie Building, the minimum value point would be 100,000. These value points were becoming more and more expensive!

"Spend it! Spend it! It's annoying to watch you keep the valuables and not spend them!"

"Only when you spend money can you realize its value. No wonder it's called a value point."

Having made the decision, he didn't hesitate and paid the fee immediately.

Even after charging, the service at Wanjielou is still very good.

A golden light appeared in the storage space, scanned the three treasures, and then appeared above his head, illuminating his entire body.

After a few minutes, the golden light began to dissipate, and a message came into my mind.

Wanjielou suggested that he take the two energy fruits first, and also gave the order in which to take them.

Although no specific data is given, there are still some simple introductions.

The energy fruit not only contains energy that can enhance mental strength, but also some energy that plays a supporting role.

It can be understood as a catalyst.

The crystallization of spiritual power is pure energy, and it is a bit rough to increase it.

He has used four spiritual power crystals in a row, and continuing to use them is not the best option.

My mental power has increased by more than 3,000 Hz, so it's time to give my brain core a break.

Now taking energy fruit, the mild energy in it can not only enhance mental strength, but also nourish the brain core.

Moreover, Wanjielou recommends taking it directly orally and not letting it be absorbed by the brain core, because the catalytic energy will not be absorbed by the brain core at all and will be wasted.

Everyone always says that using the brain core to directly absorb natural treasures is very inefficient!

Directly taking the energy fruit that can increase one thousand hertz and letting the brain core absorb it can increase mental power by up to six hundred hertz.

In fact, there are a lot of auxiliary energies that are filtered out by the brain core!

However, sometimes you have to do this to avoid drug resistance.

After reading Wanjielou's tips, he decided to meditate for an hour to digest the three sword techniques he had learned before.

Even machines need maintenance, let alone the brain core?

Being too rough is not good!

An hour passed quickly, but in Zhang Haoran's opinion, it was just a moment. He was just a little more familiar with the use of the Overlord Sword Technique, and an hour had passed.

He couldn't help but sigh, "Ah! There is no time limit for cultivation. No wonder those strong men stay in seclusion for dozens or even hundreds of years. The great way is too mysterious and it is easy for people to get lost in it.

It seems that it is unrealistic to rely on my own understanding to comprehend these sword arts. It will take too long. I should spend money to gain enlightenment!"

“The effect of epiphany is good, but it also costs real money!”

"At the third level, the fee for one enlightenment is one million value points, and at the fourth level it is ten million! The cost of two enlightenments is enough to summon Su Xiao to join the battle!"

As he entered the fourth level, the welfare period of Wanjie Building ended. He found that his expenses were increasing. It seemed that he could no longer be satisfied with his previous gains. He had to grab at least one more mineral vein.

Prepare for a rainy day!

After his condition was almost adjusted, Zhang Haoran took out a brown energy fruit and swallowed it directly.

The energy fruit melted in his mouth, and he immediately felt a warm current spreading throughout his body. It was indeed an emperor-level energy fruit, which not only enhanced his mental strength but also nourished his body.

Although it did not increase his qi and blood, it made his golden body more resilient.

Zhang Haoran still focused his attention on improving his mental strength, feeling a surge of energy rushing into his sea of ​​consciousness, which made his mind clear and his mental strength began to slowly increase.

This time the feeling was different from when absorbing spiritual crystals. The feeling of absorbing spiritual crystals was like sucking in a big mouthful of energy. As long as you can hold on, you can quickly increase your mental strength.

It took him less than an hour to absorb four crystals.

However, this energy was very gentle and easily absorbed. His mental power was slowly increasing, with one Hertz of mental power added every few seconds. Moreover, the new mental power did not need to be tempered by sword intent at all, as if it was growing naturally, but the process was accelerated many times.

At the same time, there were wisps of silver mist rising in the sea of ​​consciousness. As soon as these mists appeared, they were divided up by the two sword spirits. They were so skilled at it, as if they had done it countless times.

After absorbing the silver mist, the sword spirit did not grow, but became more solid.

These silver mists are the developed soul power.

In fact, as Zhang Haoran's strength increased, his soul power also continued to grow stronger. Soul power often entered his sea of ​​consciousness and was absorbed by the two sword spirits. However, the amount that appeared normally was too small and almost invisible.

This time, the speed at which the soul power appeared was much faster, reaching a level visible to the naked eye.

It is indeed an imperial energy fruit! The improvement is comprehensive.

Although the focus is on improving mental strength, the soul and body also receive considerable benefits, and even the brain core is nourished!
