Deep underground, there is a soul laboratory that Rosen built at great expense.

The laboratory is equipped with phase confinement arrays, mind shielding arrays, ring amplification arrays, soul focus arrays, etc., a total of more than twenty arrays.

It cost 200,000 Oggs to build this magic array, which is equivalent to spending 300 million in the previous life to build a personal laboratory.

The purpose is to provide him with the best environment for practice.

Sitting alone in the array, after confirming that the array was functioning well, he closed his eyes and began to build a 'spiritual power pumping system' in the outer layer of his soul according to the known soul knowledge.

From another perspective, this is a large soul magic circle engraved on the soul.

Extremely difficult!

Because it's like a doctor using a scalpel to perform surgery on himself, it's literally risking his life.

When engraving, one can easily feel the sharp pain in the soul.

This is a manifestation of soul shock, which cannot be weakened by any means. If Rosen did not possess the ultimate ten-ring soul, he would not be able to withstand it.

The good news is that everything is as expected, and all the pain occurs on the surface of the soul and does not hurt the root.

After the engraving process lasted for an unknown amount of time, the 'Spiritual Power Pumping System' was completed.

'Laifu, I'm going to start the trial run and monitor the running status.'

'Already monitored.'

Rosen tried to run it.

As he did this, he felt a sudden shock in his heart, and an extremely powerful force of the magic ring directly poured into his soul, almost sending him away.

He stopped running immediately and secretly wiped a sweat in his heart.

"The power pump is turned up. The pressure of the tenth magic ring is really damn high."

The power of the tenth magic ring is very abundant, the ring pressure is extremely high, and with a water pump for absorption, even though he has deliberately lowered the operating power, he can hardly withstand the magic power that is almost gushing into his soul.

"Laifu, how was the spiritual power pump running just now?"

'Everything is working fine, exactly as expected.'

In this case, you can try to upgrade the ring.

How to upgrade the ring?

Of course, it still depends on the spiritual power pump.

Taking a deep breath, he started the spiritual power pump again, and to ensure safety, reduced the operating power to an extremely low level.

A huge amount of power from the magic ring poured into the soul again. Part of it entered the 'combustion chamber' and burned, turning into the power to drive the spiritual power pump, while the other part entered Rosen's soul, dramatically increasing his soul strength.

During the whole process, as much as 90% of the spiritual power was burned.

But even if only 10% entered the soul, the soul's strength began to increase rapidly, and soon touched the wall of the tenth magic ring.

Rosen clearly felt a kind of pressure, as if there was a rocket under his butt, but there was a ceiling above his head.

Is it to break through the ceiling and fly into the sky?

Or did his body just crash into the ceiling and shatter his soul? This depends not only on the experimental data, but also on his personal willpower.

Because in the path of spiritual practice, idealistic elements account for at least 30%.

If your will is not strong enough, the artifact in your hand is useless.

Rosen gritted his teeth and held on.

At this moment, he had a pure yearning for a higher level of magic in his mind, as well as a strong belief in protection.

The mentor, wife, children, and those beautiful, lively and unique women are the most beautiful scenery in the world.

It would be such a shame if everything was destroyed by the devil.

He didn't know how long it had been, but he vaguely felt the heavy pressure on his soul suddenly lighten, and then his whole body suddenly became light.

If the pressure was too great the moment before, now the pressure is too little.

Too much pressure can shatter the soul, but too little pressure can cause the soul to disintegrate from the inside out.

All of a sudden, all kinds of thoughts popped up in my mind uncontrollably, and I even felt like a group of demons were dancing wildly, and I couldn't tell the difference between reality and illusion.

This is a sign that the soul is about to collapse!

'I've reached the eleventh ring, and it feels very similar to what Naya described!'

At this time, the experience provided by Naya played a good guiding role to Rosen, so that he would not be at a loss because of being in a completely unfamiliar situation.

He kept his mind to himself and immediately began to execute the planned plan.

'Increase the power of the spiritual energy pump to prevent the spiritual energy from flowing back.'

'Activate the soul shield and stabilize the soul pressure.'

'Turn on the spiritual energy cooling system to stabilize the spiritual energy combustion chamber.'

'Activate the soul shielding array to isolate soul vibrations.'

'Laifu, start collecting data and training the new ability "Legendary Ring".'

'Collecting data'

As the power of the spirit pump increased, in Rosen's soul combustion chamber, the soul power burned fiercely in the spirit furnace, and the stimulated power maintained the consumption of various soul spells.

Just as he expected, the whole process was extremely complicated, and it took a huge amount of energy just to maintain it.

The most terrifying thing is that as long as you relax for a moment, this sophisticated and complex soul system will stop working, and then the terrifying "spiritual power backflow" will occur.

According to the experimental conclusion, the violent backflow of spiritual power will cause the soul to collapse in just 3 seconds.

Rosen tried hard to maintain it, with only one thought in his mind: "This is just playing with his life!"

Why is this happening?

Why didn't the demonic power previously require so much effort, and could exist for a long time even without the main body's magic power?

Rosen was not clear before, but now he understands.

Because the eleventh Dharma Ring is directly connected to the void outside the ring, it can even be said to be the void outside the ring!

Demons are native creatures born in the void outside the ring, just like fish living in the sea, and they are naturally fully adapted to the void environment.

Mortals are originally land creatures and should not live in the sea.

Now, Rosen is wearing a 'diving suit', building an 'underwater oxygen supply system', and trying every possible way to dive into the sea. It's good enough for him to be able to survive in the sea, and naturally he can't be as calm and comfortable as a fish.

What should I do? 'Laifu, have you learned it? ! '

Although the various soul spells are cumbersome to maintain, the void environment is not complicated. As expected, Lai Fu should learn quickly.

'I have completed the initial learning and gained the ability "Soul Burning Secret Method".'

'Start the "Soul Burning Secret Method" and run it in the background.'

With this order, Lai Fu successfully took over Rosen's job.

In order to avoid accidents, Rosen did not stop the Soul Burning Secret Technique, but tried to maintain it while observing the operation of Lai Fu.

Rosen's idea was simple: run two pumps at the same time to maintain redundancy.

Otherwise, if one of them breaks, he would be caught off guard.

After a careful inspection, he found that Lai Fu was functioning well, and the spiritual power obtained by the spiritual power pump was much more stable than his own. He immediately felt relieved.

"Laifu, open another "Soul Burning Secret Method" and run it in the background, but keep it running at the lowest power."

Lai Fu did as he was told immediately.

Then, Rosen stopped practicing the Soul Burning Secret Technique and began to concentrate on observing Lai Fu's operation.

After looking at it for a while, Rosen asked: "Laifu, how much computing power does it take to maintain the "Soul Burning Secret Method"? "

“Currently 25% of the computing power is needed.”

This consumption was very alarming, which meant that Rosen's three-line operating ability was dragged down by the Soul Burning Secret Technique, and the Duke Puppet occupied another line, so he only had one line left.

But this is only temporary, as Laifu’s total computing power has also increased.

"The soul has become much stronger. Has the total power increased?"

“The total computing power is increasing, and no limit to the increase has been found.”

“Very good!”

Rosen carefully checked the strength of his own magic power and found that it had increased by about 20% compared to the peak of the tenth ring, and was still increasing at a considerable speed.

At the current rate, if there is no limit, it is estimated that the current base value can be increased by 5% per hour, and it can be doubled in 20 hours! This is really crazy, and even Rosen decided to be a little scared.

Now the magic circle has no limit, but life has a limit! The mortal soul and the biological brain are completely integrated.

Once the life limit is exceeded, my brain may collapse.

However, the brain is too complicated and Rosen has not fully understood it, so there is naturally no way to improve it, so he does not dare to take risks easily.

Furthermore, if the soul power increases too quickly, it will itself cause violent soul shocks and may even cause the soul to collapse.

"Laifu, reduce the power of the spiritual power pump to maintain the stability of the soul strength. After the soul shock disappears, continue to increase it, but the increase speed will be reduced to 1% of the current level."

'Continue to collect data and train the "Soul Burning Secret Technique"'

Following this command, the soul gradually calmed down, and Rosen secretly breathed a sigh of relief.

He decided to move forward cautiously, bit by bit, and stop immediately if he found something was wrong.

As his soul stabilized, he focused his mind and began to carefully feel the situation of the eleven Dharma rings.

Then I noticed a lot of changes.

"The Eleventh Ring is so empty, it feels like there's no end in sight."

"Looking down, I can actually look down at the Circle of Justice."

"The magic circle is not completely calm. Will there be various ripples of power?"

In the past, Rosen could vaguely feel this change, but it was not as clear as it is now, and the range of feeling was not as wide as it is now.

The reason is simple, because he was within the Dharma Circle at that time.

When people are in a situation, they are naturally confused.

And now, he jumped out of the magic ring and looked down from high above.

In the past, he could only feel the fluctuations of the magic ring within a thousand meters around him, but now, he can overlook the fluctuations of more than ten kilometers.

As the strength of the soul increases, the range of vision continues to expand and the degree of detail also increases accordingly.

He soon discovered that the frequency of the magic ring ripples was not too high, but not too low either.

The vast majority were caused by mages casting spells, and the ripples were very small. A very small number were caused by changes in the natural environment, and the ripples were very large, even causing quite obvious fluctuations in the height of the magic ring.

As he watched, Rosen understood.

'By observing the ripples of the ring, we can infer most of what is happening in the mortal world, but not all.'

"If you want to truly understand, you need a lot of experience. This ability is very important, but relying on the brain power of ordinary people will definitely not be able to see the whole picture."

"We need to train Lai Fu to come and see."

Just like on Earth, AI is trained to look at various medical examination images. As long as the sample size is large enough, the diagnostic level will be much higher than what the doctor can see with the naked eye.

'Those violent ripples should be caused by various natural events. It is possible that they create some lucky people and make it easier for them to jump to a higher ring.'

'Some lucky people will encounter several violent fluctuations in a row, and then they will reach the high ring or even the super high ring.'

After seeing clearly, most of the pressure in Rosen's heart caused by the demon outside the ring suddenly dissipated.

"Sure enough, the path of cultivation seems unfathomable before you reach it, but once you reach it, it feels just like that."

'Even after entering the eleventh ring, one is still a mortal, just a mortal who has mastered the secrets of more powerful magic.'

But to say that cultivation has reached its peak is not right either.

Because the eleven magic rings have no limit on the strength of the soul, no one knows to what extent it can be improved in the end.

'What is the limit of what a mortal body can endure?'

I don’t know, at least Rosen hasn’t encountered it yet.

In addition, this is ultimately just personal practice. Although it is very powerful, it still cannot be separated from the support of the world.

Just like the astronauts and divers in previous lives, they can go to the sky, the earth and the sea, but they are still mortals in essence. They still have to eat, drink, defecate and urinate, and they still have to return to life.

After confirming that everything was normal, Rosen slowly opened his eyes, and with a thought, a ray of pure magic power appeared at his fingertips.

The mana is pure and transparent, like a flowing heat wave.

After it appeared in the air, it immediately decayed into various kinds of magical energies and did not exist as stably as the demonic power.

But in terms of magic power strength, it is not much different from the ice-blue demon power of the past.

The reason is clear. Demons are native species of the void, and Rosen is an imitator of mortals.

But after all, the legendary mana of the eleventh ring has a very obvious difference from the low-ring mana. It is very delicate and easy to control at will.

It even has strong control over the energy of low- and medium-level spells, and can directly snatch control of spells from low- and medium-level mages.

"Now, I am once again at the pinnacle of magic, and can focus on worldly power."

The Republic of Nahuatl that Mediana described was powerful, perfect and worthy of respect, but there was no need for him to learn it by force.

Because his legendary power relies on himself, not the cohesion of national beliefs.

In addition, his soul burning secret method is far from perfect, so the research will continue, but there is no need to rush like before.

With a change of thought, Rosen disguised his magic power, and what finally appeared was still the magic power of the early 8th ring.

This disguise is much more perfect than before, and can even deceive demons in the void outside the ring.

Because at this moment, at least in terms of magical practice, both sides are already at the same level.
