The basis of undead magic is the soul, and the soul in the soul crystal is also one of them. Even though they all belong to the same thing, will it strengthen your soul by sucking the soul in the soul crystal into your own soul?

This kind of thought suddenly arose in Rob's mind, and then he felt that his thought seemed very familiar. He quickly turned the book in his hand to the next few pages.

"For undead creatures, devouring and sleeping are two ways for the soul to strengthen its own strength. Devouring other souls is dangerous and is easily retaliated by other souls, so try not to devour souls with higher strength than yourself. The devouring effect is better and faster. Sleeping is the safest way to grow, but the growth rate is slow."

"Humans cannot strengthen their souls through devouring and sleeping. If the undead mage wants to strengthen their souls, they can absorb the ubiquitous soul energy to strengthen their bodies through meditation..."

Meditation? When seeing the description of this word, Rob suddenly thought of the "thing" that was caused by the trembling of his soul that night when he met Dalaydo. Could it be that meditation? Those "things" that trembled with his soul are soul energy?

He carefully read this book "Overview of the Magic of the Undead", thinking about the key points about devouring and soul over and over again, and Rob didn't stop until he made sure that he had fully understood it.

He took off his helmet and took a deep breath.

For him, breathing is a kind of ability that he gained after changing his flesh and blood body. In the past, the metal and wood body did not need to breathe. Of course, in the current body, breathing is not necessary, but the flesh and blood will lose its activity and gradually wither.

However, because of this need, he can grasp the skill of "swallowing", because according to the description in the book, the importance of devouring lies in the word "sucking".

Rob held the soul crystal in front of him, and the soul sucked it hard.

The blue flame burning inside the soul crystal was sucked into a line and slipped out and penetrated into Rob's head.

As if he was slapped by an invisible palm, Rob's head leaned back slightly, and his whole person seemed to be immersed in water. It seemed that something had wrapped his soul, and the whole world instantly became extremely quiet.

Rob's soul felt warm and very comfortable. This tranquility and warm feeling made his whole soul immerse himself in it, without thinking. I don't know how long it took, the tranquility slowly disappeared, and the sounds and light changes from the outside world returned to his perception, and Rob slowly came to his senses.

It was a wonderful experience. Robton fell in love with this feeling at once, and then he found that the whole world seemed to have changed.

In the past, Rob could see the words on books ten meters away, but now he could see the same size on books fifteen meters away.

The footsteps of Jirasha and No. 5 were very clear when they moved, but at the same time there were many more details, such as the friction between the soles of the feet and the ground, and the collision of joints and joints. These small sounds were previously covered by louder footsteps, but Rob could hear them clearly at this moment.

It seems that the whole world is full and there are more details, and it has greatly improved its ability to perceive temperature, whether it is hearing, vision, or even temperature.

Why is this happening? Rob focused his attention on his soul in confusion.

I obviously felt that my soul had grown a lot. According to the undead creatures' division of soul strength, this is at least a level 4 soul fire, and I actually upgraded?

Rob no longer remembers how long his soul has maintained this strength. It seems that he has been at this level since he has memory. Over the past two hundred years, his intelligence has been constantly improving, but the strength of his soul has never changed.

If it weren't for the "Overview of the Undead Magic", Rob wouldn't even know that the soul has a level difference.

Devouring the soul is indeed the key to soul upgrading. When he devoured the first soul, he actually upgraded? The changes after the soul upgrade also made Rob very excited, his perception ability was greatly improved, his energy was very abundant, and his soul seemed to be full of power.

Unfortunately, one-time devouring cannot accumulate more data, and Rob couldn't wait to devour the second time. He walked to the shelf and checked the soul crystals, hoping that new souls had already formed inside.

He didn't have much hope at first, after all, the soul's pregnancy cycle is too long, and it is unlikely that the soul will be produced continuously. But after a closer look, there was a dark blue flame in one of the soul crystals.

Luckily, Rob was a little grateful. When he picked up the soul crystal, he turned around and looked around. There were three trays on the table at the entrance of the basement.

Rorynx will be delivered on time for three meals a day. Sometimes when you get busy, Rob is too lazy to eat. After all, food is not the main source of energy. But if Rob is not collected, you can eat as much Rob there in one breath.

Over time, Rolins became accustomed to it. As long as the food was not broken, she would not take it away.

I remember that before he devoured his soul, there was no food on the table, but now there are three more portions of food. Did Rolins deliver all the three meals in one breath?

Turning back to look at the magic timing hourglass on the wall, the data on it showed that it was already late the next night. The loss of the soul that Rob devoured his soul actually passed by a whole day and a night?

In that state, you can't feel the passage of time? Even Rolins didn't even notice it after three times. In this way, devouring can only be carried out in a very safe situation, otherwise you will not be able to react when you encounter danger during your loss.

Rob walked to the table, cleared all three portions of food in one breath, and then came back. This time, he stopped holding the soul crystal. He lost his mind for a day and a night. Who knows if there will be any changes during this period? If he accidentally dropped the soul crystal to the ground and shattered it, the loss will be huge.

Before devouring the soul, Rob did not pay special attention to the soul crystal. After all, he had no time to use the ten soul crystals produced, so it didn't matter if he lost one or two. So he only released five of them, and the soul crystals left in the storage space could not nurture the soul.

But now, the souls nurtured in it can actually strengthen its own soul strength, so the more souls the better. One more soul crystal will have more growth rate.

Thinking of this, Rob quickly opened the storage space and took out all the other soul crystals.

After putting it on the shelf, Rob came to the crystal that had already nurtured his soul and sucked it hard.

Another force as thick as an invisible palm hit him on the face, and Rob once again fell into that state of tranquility without thinking.

After a long time, Rob came to his senses and looked in the direction of the timing hourglass as soon as possible. It took another whole day and night, and three more trays were placed on the table next to the door.

Although it was the second swallowing, Rob felt that his improvement was still very obvious. He could see the words on it clearly when he put the book twenty meters away, and the other details became richer. This change was even as fast as he had just changed from a metal and wood body to a flesh and blood body.

The strength of the soul did not enter a higher level, but jumped from the early stage of level 4 to the late stage. Calculated according to the amplitude of this change, if there is another soul, he can enter the strength of level 5.

The questions that had troubled him for more than two hundred years finally found the answer. This is a very happy thing. He finally understood the real reason why the soul of the shadow structure is stronger than him. It turns out that the soul can be upgraded.

He looked up at the shelf. After a night, the crystal placed on the shelf did not produce a new soul. At this moment, Rob focused all his thoughts on soul enhancement. No new soul was generated. He was a little disappointed and his body and mind were relieved.

After relaxing, Rob suddenly felt a little tide on his body.

Rob instinctively disgusted with this feeling. When he was in the magic tower, his golden wood body was often eroded by moisture, which forced him to seize the brief time when the sun was slanted every morning, and use the sunlight projected from the windowsill to dry his body.
