“...... The presence of oxygen is fundamental to the survival of humans and all kinds of itchy species. Brain cells begin to die after five seconds of oxygen deprivation in the human brain...... The transport of oxygen in the human body depends on the circulation of blood, and the lungs are the organs where the body's blood receives oxygen and emits carbon dioxide. Blood depends on the presence of blood vessels and maintains the power of circulation through the scaling of the heart...... Blood is made up of plasma and blood cells......" Guderian wrote in his tent the knowledge that Alice had injected into his consciousness, while Natasha stood quietly and watched.

"There are so many incomprehensible phrases...... Natasha said as Guderian stopped writing.

"These are easy to understand as long as you use your spiritual power to probe and confirm them in your body. Guderian put down the goose feather tube, stretched and took Natasha into his arms.

“...... Although I can detect my inner spiritual power into my body, I can't perceive such a subtle level. Natasha put her arm around Guderian's neck and wondered.

“...... What is the difference between being dull or not?" Guderian was also puzzled. In his own perception, with the growth of spiritual power and the accuracy of his control of spiritual power, he is more and more comfortable with his own detection. As soon as the cell said, it was seen from the notes of Fortan Julis, and Guderian also verified it.

"Yes. A familiar voice came in as the curtain of the tent opened, and an old man with white hair walked in with the cold wind and snowflakes.

"Uh...... Lord Gandalf. Guderian and Natasha hurriedly parted, and stood up with some embarrassment to say hello. As he spoke, he walked around the desk and came to the fireside in the tent.

"Hahaha, Guderian, Natasha, congratulations. Gandalf laughed, and sat down by the fire.

Guderian and Natasha also sat across from Gandalf.

"The master came back so quickly, I thought it would take a while. Guderian motioned for Natasha to prepare some hot tea ceremony.

"As soon as Douglas's arraignment arrived, I rushed back. I had been checking around the various passages that had been blocked by Drow. Gandalf said.

At this time, two more figures opened the camp curtain and walked in.

"Gandalf, I knew you would be the first to come here. "It's Master Martin and Douglas who come in, and it's Douglas who speaks. The two of them also sat down by the fireside.

"Lord Douglas, Master Martin. Guderian greeted them one by one, and the two nodded in response.

"Where's Fortan Ulys's notes?" Gandalf squinted at Douglas and Martin, and said to Guderian with impatience.

Guderian quickly got up, returned to the desk, flipped out an old black cover notebook, and handed it to Gandalf. Gandalf took it and opened it to dive in.

“...... The medium of the soul is the combination of consciousness and mental power, which exists on the basis of the brain......" Gandalf looked at and occasionally read out passages.

The crowd did not disturb Gandalf as he read, and there was silence among them, gathered around the fire, holding teacups, and drinking Natasha's hot tea. After a long time, Gandalf probably skimmed through the notes before closing the notes, and then pondered: "Passivated spiritual power and non-passivated spiritual power, the former can reach the subtle level in the life medium, and the latter can only be reached in the external release. So Natasha can't detect the same level in her own body as you do, otherwise she would have mastered the blood. And you, Guderian, have no way to communicate with the magic power and activate the magic after exerting the mental power. ”

Gandalf explained to Guderian and Natasha when they first came in, and then paused and continued: "Based on our research with Fortan Julis, our necromantic family wanted to summarize the attributes and categories of souls, but it was in the wrong direction. It is too much to take for granted to study the method of spiritual power passivation from the attributes of the soul. The soul has no attributes!, but Fortan Julius's notes gave me a clear direction. The brain of a creature like a lich is dead, but its soul is not dissipated, but solidified - the so-called solidification: for example, the soul is water, the brain is a bucket or a bowl, as long as a certain temperature is maintained so that the water is frozen, it does not matter whether there is a bowl or a bucket. So, is the passivated spiritual power just between the ice water?" Gandalf's eyes lit up, and the more he spoke, the more excited he became.

“...... Quite possibly!" Master Martin picked up and slapped Douglas heavily on the back.

“...... Old boy!" Douglas, who could hear it, was slapped and almost threw himself on the stove, and couldn't help but say angrily. But the smell of burnt hair made him have no time to pay attention to it for a while, and jumped up to check his beard.

"Yes! It must be so! Guderian, let me check. Gandalf ignored Douglas and Martin, and couldn't wait to pull Guderian over and instantly inspire a huge spiritual force to envelop him. Before Guderian could react, his own spiritual power was instinctively stimulated to form a membrane that filled the surface of his skin.

“...... Hmmm?......" Gandalf's face was cloudy, and Douglas, Martin, and Natasha all looked at the two nervously for a moment.

“...... Yes, so it was!" Gandalf let go, and Guderian jerked to his feet, walking excitedly around the tent.

"Gandalf?" Douglas called out cautiously.

Gandalf was woken up by Douglas, paused, and then laughed: "Guderian, it's my luck to meet you!" Gandalf smiled and sat back on the edge of the fire in the expectant eyes of everyone and said excitedly: "In terms of water and ice, the soul of the lich is solidified into ice, the soul that can stimulate blood control is the state of ice water that wants to be solidified but not solidified, and the soul of us mages is in the state of water. Then you can find a way to blunt your mental power! This can also explain why there are still some people in Loris who can control blood and cast magic. ”

Douglas and Master Martin also suddenly realized.

"How simple is that?" said Douglas.

"Simple? We thought about it, and we experimented for more than two thousand years, and if it weren't for Fortan Ullius transforming the lich and Guderian bringing back his notes, we would have been studying in the wrong direction!" Gandalf glared at Douglas.

"......" everyone couldn't help but fall silent. Fortan Ulis deserves to be the archmage with the most promising chance of stepping out of the end of spells that year. Even if he transforms the lich, the knowledge he has and the things he studies are so admirable.

"Then, the passivation of spiritual power requires a fuss in the transformation ritual of the lich...... But, apart from Fortan Ullis, where do we go to convert the method of ritual?"

The transformation ritual is actually in his notes. Gandalf said confidently: "I'll sort it out in the next few days, and then I'll need Douglas and Martin to help you experiment." ”

"That's fine. It's just a pity that Roglis set off for Dayu, otherwise it would be more suitable to start from him and compare the improvement of the ritual. Master Martin said regretfully.

"Don't think about it, I get angry at the mention of him. Gandalf pouted. It seems that the unpleasant relationship between Gandalf and Roglis has been haunted by Gandalf all along.

"......" Guderian and Natasha looked at each other speechlessly. This old man holds a grudge, don't offend him in the future.

"By the way, Guderian, what were you and Natasha writing when I came in?" Gandalf asked suddenly.

Hearing Gandalf's inquiry, Guderian hurriedly got up and took the notes he had written before from the desk and handed them to Gandalf and said, "Some knowledge about the structure of the human body." ”

Gandalf became even more curious when Guderian said this, and took the note and looked at it.

"Huh...... Where did you learn that?" Gandalf asked after reading a few pages.

“...... Uh" Guderian glanced at Natasha and said, "After learning the meditation method you gave, my mental power has continued to improve, and I have become more comfortable exploring my body. So I made some notes. Guderian didn't want to tell Alice about it. Of course, sooner or later, the things of the earthlings have to be spoken, but not now.

“...... Interesting saying...... Well...... Much more thorough than our research......" Gandalf did not doubt him, and immersed himself in Guderian's notes.

"It seems that your strength has reached a higher level. Throughout the ages, there has been no one who has reached this subtle level of blood control who is not a super-first-class master in the famous continent. The afterlife is terrifying!" Gandalf said, closing his notes.

"Among the masters of the kingdom, except for the old Odin, they are all headed by Rogris, and it seems that Guderian is going to replace Rogris. After listening to Gandalf's words, Douglas nodded in agreement.

"Definitely. At the previous station behind enemy lines on a snowy night, Guderian was able to kill those two underground archmages in a thousand armies, I thought it was just luck. Now it seems that I was wrong. Although they did suffer heavy damage, the Extreme Cold Realm and Thor's Fury could not be faked. can break through the extremely cold realm in the thousands of armies and resist the wrath of Thor and kill them, except for old Odin and you, there will be no third person in the kingdom. Master Martin also sighed.

"Thank you, Lord Douglas, for saving your life. Guderian said modestly.

Gandalf didn't know why, and looked at Douglas and Martin suspiciously. So Master Martin recounted the aftermath of that night's battle.

Gandalf heard this, and looked at Guderian again seriously.

"Don't do this kind of stupid thing in the future. Douglas gave you the Reaper's Shelter once, and the potion won't work for you anymore. Think about the consequences before you do anything!" Gandalf said angrily and fearfully.

Guderian had to accept Gandalf's lesson in embarrassment, not expecting the old man to care so much about him.

"The kingdom can't afford to be compromised by high-end forces. Your father, Natasha, can't accept your death either. However, Guderian, your strength did not disappoint me!" Gandalf said with his final appreciation.

Later, at Gandalf's request, Guderian and Natasha recounted the underground experience, and then the crowd discussed Guderian and Natasha's experience again......
