"Hehe, there are almost countless resources to practice in the City of Mystery. Whether it is building spells, alchemy, runes, puppets, etc., as long as you are building spells, alchemy, runes, puppets, etc., you will make progress faster than other places. However, the City of Mystery is not open at will, and requires adventure points. However, the City of Mystery must help the City of Mystery solve some problems, and there may be great dangers, so that you can get a small amount of adventure points. Apart from this, there is no other way. The City of Mystery will not reward any spellcaster."

Arrot introduced in detail how to obtain adventure points, and he could only go out and take risks. For example, in a certain plane, the great legend felt that there was not enough manpower and needed some powerful spell casters to help suppress the plane.

For example, killing some powerful aliens can also obtain some adventure points. However, the one who gets the most adventure points is to discover a masterless plane. As long as this plane is not a barren plane and has elements, there is no need to control this plane. Just provide a specific plane coordinate to obtain rich adventure points. At that time, the City of Mystery will naturally send some great legends to control the masterless plane.

In short, if you want to get adventure points, you need to go out and take certain risks.

Of course, with adventure points, you can also gain huge benefits in the City of Mystery. These are some cultivation environments that even the great title legend envy, and are only available in the City of Mystery.

Merlin had no adventure points at all. He heard Arot say that the spiritual tower was very beneficial for the tempering of mental power, but without adventure points, he could not enter the spiritual tower.

"By the way. Has Master Sartan gone out to take risks? Otherwise, how could he have adventure points to enter the spiritual tower?"

Merlin and Satean entered the Mysterious City together. However, Satean had already broken through the Spiritual Tower. He must have benefited a lot. Merlin also became a little active in his heart, thinking about taking risks, and getting some adventure points first.

However, Arot quickly shook his head and said, "Master Sartan did not go out for adventure. The reason why he was able to enter the Spirit Tower is because the Spirit Tower is open to the casters who first broke the tower and do not need to consume adventure points."

Merlin was slightly stunned. The City of Mystery would never give potential mages any adventure points. However, it can be used for free in some places without any points, which is equivalent to helping potential mages in disguise.

"Since it's free, it's not too late, I'm going to try it out now."

Merlin can't wait to explore the spiritual tower.

Arot hesitated for a moment and said, "Master Merlin, you have to think clearly that this spiritual tower only has one free chance. The stronger the mental power, the more you may gain from entering the spiritual tower. Many potential mages wait until their mental power has made great progress, and then they can take advantage of the free opportunity to break into the spiritual tower."

"Haha, don't wait long. If the effect is good, you can get more adventure points in the future."

Merlin is now at a time when his mental power is growing, so he will wait slowly. Therefore, under the leadership of Arot, he quickly flew towards the spiritual tower.

"Swoosh".

Merlin and Arot landed in front of the spiritual tower. The spiritual tower was only sixteen floors, but each floor was very high, with a total of sixteen floors. Looking up, I couldn't see clearly.

"Arot, have you broken through the spiritual tower and what level have you reached?"

Merlin looked at the towering spiritual tower and turned his head to ask Arot.

Arot scratched his head slightly, and finally thought for a while before saying, "I did break through the spiritual tower, but I only broke through the eighth floor at the beginning."

"On the eighth level, where is Master Sat'an?"

Merlin was very curious about how many levels Sarthan could reach. After all, Mage Sarthan is also a six-type spell caster, and he also needs a lot of mental power. As a seventh-level spell caster, Mage Sarthan's mental power is probably at least comparable to the mental power of a level ninth-level spell caster.

Of course, if Master Sart'an did not condense his spiritual heart, the level of mental power required would naturally be very high. Merlin has a strong spiritual heart and has more mental power to accommodate, so there is naturally no need for continuous breakthroughs in the spiritual level.

Once Merlin reaches the limit of the seventh level spiritual heart, he will be very powerful. If he can fill his spiritual heart with mental power, Merlin can even build a complete sixth level spell in one fell swoop, so as to become a sixth level spell caster in a very short time!

Master Arot pondered for a while, and finally whispered: "Master Sartan is so powerful. He can actually break into the eleventh level spiritual tower!"

“Eleventh floor?”

Merlin didn't know what the eleventh floor of the Spirit Tower meant. He still needed to go to the Spirit Tower himself to know how difficult the eleventh floor was.

Merlin kept the progress of Sart'an's eleventh floor of the spiritual tower in his mind, and then showed his identity and stepped into the spiritual tower.

"Although Master Meilin's mental power is also very strong, he should be able to reach the eighth level, right? Perhaps the eighth level is also a bit difficult..."

Arot was silently muttering, but the situation of the spiritual tower was not visible outside, so Arot could only wait quietly outside.

"Swoosh".

Merlin stepped into the spiritual tower, and his mental power quickly began to check around him. He found that there were three other strange casters who entered the spiritual tower with him.

These three strange spell casters, without exception, have relatively strong mental power. It seems that they are the first time they have entered the spiritual tower, and they seem a little cautious.

"I heard that the spiritual tower is very strange. Even on the first floor, be careful!"

The three strange casters seemed to know each other, and the three of them leaned back together, very cautious. They seemed to have seen Merlin, but they did not intend to invite Merlin to break into the spiritual tower together.

Merlin didn't spend much time on these three people. He began to carefully look at the first floor of the spiritual tower. In the dim first floor, it was empty and wide, but he didn't feel anything special.

"What does spiritual tempering mean?"

Merlin was still thinking carefully about the role of Arot mentioned by the spiritual tower, which is to sharpen the mental power and increase the mental power quickly.

"Hiss, it hurts so much!"

Meilin's mouth twitched slightly. In an instant, he felt a faint pain in his mind, and his face immediately changed drastically. The pain did not disappear, but instead slowly spread to Meilin's whole body little by little.

Not only Merlin, but also the three spellcasters, had a look of pain on their faces at this time, and they also felt the pain of their mental power being torn apart.

"You can still bear it, you must endure it!"

The three of them roared lowly. They knew that this might be the test of the first level of the spiritual tower. After Merlin felt the pain at first, he quickly recovered. His spiritual heart was extremely powerful. In addition to accommodating mental power, he could also protect mental power.

The unparalleled pain tortures the three of them, and even Merlin could hear the low moans of the three of them, which were moaning in pain.

Merlin frowned. Except for the initial mental pain that he couldn't bear, his mental power is now only a little bit of pain, which is the role of the spiritual heart.

"Just pain? This is stimulating mental power, is the spiritual tower that simple?"

Merlin was a little surprised. His mental power was actually the lowest method to directly stimulate his mental power and make the caster suffer. However, if he could tolerate it, his mental power could be quickly improved.

Although Merlin is protected by a spiritual heart and is not very painful in the first floor of the spiritual tower, he can also realize that his mental power has indeed increased a little.

Merlin did not rush to enter the second floor of the spiritual tower, but waited until the three of them gradually recovered, and then a hint of joy appeared on their faces.

"It has increased, and the mental power has indeed increased. This spiritual tower is really magical!"

The three of them were all excited. On the first floor of the spiritual tower, their mental power increased greatly. Even the pain just now had long forgotten it.

"Swoosh".

Then the three of them arrived at the second floor, and Merlin followed closely behind.

When we arrived at the second floor, the few people soon had a clear feeling. This time, it was still painful, and it was several times more painful than the first floor.

Even Meilin, with the protection of his spiritual heart, still felt that his mental power seemed to be pulled out and torn apart.

This kind of pain is simply indescribable, just like the head is being torn apart alive. This most intuitive pain directly stimulates the mental power to grow wildly.

Originally, mental power needed to be stimulated to increase rapidly. For example, some of the potions that Merlin had swallowed before stimulated mental power and made Merlin suffer, which made mental power soaring.

Now, in the spiritual tower, the mental power seems to be controlled by an invisible force. Without taking any medicine, it can make the mental power extremely painful and soothe mental power.

The three of them were already wailing. Although they were enduring it hard, their bodies were trembling, as if they could not hold on at any time.

Merlin took deep breaths, enduring the pain of his mental power being torn apart. His willpower was very strong. Although it was very painful, there was no sign of collapse.

As time went by, Merlin felt the pain gradually ease, and his mental power increased again, but this time it grew much faster than when he was in the first floor.

"The third layer won't be more painful, right?"

Merlin looked at the top of the spiritual tower. Even if it stimulated mental power, there must be a limit. Once it exceeded the limit, not only will the mental power not increase at all, but it will collapse instantly.
