After Ding Long came to look for her once, Zhou Heng's days were suddenly exceptionally peaceful. When the news of him being in contact with Ding Long spread out, most of the students in the school avoided him. However, Miss Tong and the others did not seem to be affected by this matter and continued to maintain contact with Zhou Heng in the school.

Xu Lingshan was still lying on the sofa in Zhou Heng's house. In the past few days, Xu Lingshan's corpse did not show any signs of rotting, so Zhou Heng decided to observe for a while more. Xu Yi also never returned to school.

And Zhou Heng could finally learn the third book in the Heavenly Teacher Library.

To most students, studying was a painful thing, but no one suffered at a higher level than Zhou Heng.

He was sitting cross-legged on the bed, browsing through the treasures in the Heavenly Teacher Library, frowning at the same time.

The process of his brain being forced into his words and knowledge was just too painful, as though there was a pair of invisible hands holding a scalpel to modify his own brain. Even Zhou Heng, who had an extraordinary ability to resist pain, felt fear towards this kind of pain. "Fear" was the most important emotion a human should have to protect themselves. If not for this fear, Zhou Heng would have died from the overlapping pain if he had continued to read in order to raise his ability.

According to past experience, the more content a book had, the more pain it would experience in reading it, but the ease with which the content would be read did not affect it at all.

Therefore, it would be useful for Zhou Heng to try his best to choose, and read fewer books.

Unfortunately, most of the books with simple and useful contents were unable to be unlocked by Zhou Heng, and many of the books that he could read were all thick and thick. It looked deadly.

"Change the key word." Zhou Heng ordered the Heavenly Master System, "I want to search for a 'doctor'."

Medical skills were also a very useful ability. A huge volume of medical books immediately appeared in front of Zhou Heng.

Zhou Heng didn't even want to try reading the nearest few medical books that were as thick as a dictionary. Just wait until he felt that reading them wouldn't cause him any more pain, and he might be interested in coming back to take a look.

After looking around for a long time, Zhou Heng saw a book that caught his eye. Although it was not very thin, but under the circumstances, the title of the book would allow Zhou Heng to have some expectations towards the book.

Zhou Heng took a deep breath, then placed his hand on the cover of . The moment he determined that he wanted to read it, he opened the book in front of him.

Zhou Heng who was already familiar with the process closed his eyes and focused on resisting the incoming pain.

Intense pain hit him as expected, Zhou Heng was gradually unable to support his body, he fell on his back, and gasped for breath.

had only been instilled for less than five minutes, but this little amount of time made Zhou Heng feel like it was nothing. When he closed the book again, the pain had also slowly disappeared.

This time, Zhou Heng did not faint.

He examined the knowledge in his head. Sure enough, he had a new understanding of medicine, and the shapes and names of countless herbs appeared in his mind. He knew the characteristics and uses of every single herb, even though he had never seen most of them before.

Following that, Zhou Heng laid on the bed for a while longer. Reading Divine Agong Medical Arts had nearly drained all of his energy. At this time, the white cat jumped onto the bed.

The exhausted Zhou Heng stretched out his hand to rub the white cat's fur. Recently, the white cat had stopped bothering him to go out with her, as if it had gotten used to living here.

For example, it didn't want to eat cat food, and it never took a bath with Zhou Heng. However, Zhou Heng had already gotten used to these ailments, so compared to living here by himself, an extra cat was a little more lively.

Gradually, the fatigue in his body receded, and at the same time, he recovered a little bit of his physical strength.

Zhou Heng closed his eyes. He did not want to use the Heaven Mage System, but to gather all the energy in his body — — The energy of the magic was different from the "mana" bestowed by the Heaven Mage System. It could not be converted from physical strength. However, the energy of the spell was equally efficient. It could be released and gathered, while transforming into various forms.

Useful, but precious.

At the same time, there was another use for energy spells — this was the true usage of energy spells. Spell energy was originally a type of life energy that European Magi developed to deal with strange beasts. In the Obscure Era of Europe, humans could not rely on guns and ships to protect themselves from strange beasts, they could only rely on their own blood and flesh. During the bloody battles with strange beasts, some intelligent warriors found the remaining life energy in the corpses of their comrades and refined it into a kind of magic energy that could be transformed and remolded. They became the first batch of Magi, using their magical powers to kill the strange beasts and protect the humans of Europe. It wasn't until six hundred years ago, when the witch trial happened, that the witches left European history and hid in the tower.

The energy of the spell was originally meant for hunting strange beasts. It had a natural ability to sense the baleful aura emitted by strange beasts. In other words, the energy of magic and killing aura were similar to the yin and yang of the same thing. The former originated from the life energy of humans, while the latter came after the death of wild beasts.

The system helped Zhou Heng analyze all the characteristics of the magic power and transferred them into his mind. Most of the Magi today could not even compare to Zhou Heng in the research on the power of magic. The only thing he lacked was the reserve of energy for spells.

Because the magical energy originated from life energy, everyone had a little bit of life energy in their body. However, if this tiny amount of life energy was to be converted into magic energy for battle, it would only be a drop in the bucket. Unless it was a large-scale massacre or inherited from the ancestors, it would be difficult for one to gather a large amount of magic energy.

Behind the Magus King's extraordinary strength was the blood and flesh accumulated from generations of massacres and deaths in Europe. In this generation, there would be six Magus King s. It was because of the outbreak of the two world wars in Europe that a large number of dead people had appeared in Europe. The Magi had obtained the remaining life energy from the dead, and then killed each other in order to obtain the energy of the other Magi. The thrones of the six Magus King s were all made from piles of bones.

At the moment, Zhou Heng was releasing the magic power from his body. He was sensing the faint Evil Qi flowing in the Coastal City.

With the continuous diffusion of the limited energy, the energy released by Zhou Heng became thinner and thinner, but these thin energy interweaved with the baleful aura in the air.

Zhou Heng felt that his own Spell Energy was being pulled towards him, towards the source of the biggest killing intent in Coastal City.

It was a dragon, a dragon at the bottom of Qingyu Lake!
