When Marshal Odin withdrew to the El Niño Line with the main force, Guderian was pulled away by the furious Gandalf before he could ask the Marshal for leave.

"Guderian, let me test your mental power. Gandalf took Guderian to his tent and took out the psychic device from his waist bag for Guderian to take with him.

"......" Guderian looked at Gandalf with excitement and anticipation, and had to obediently comply.

After a burst of red, yellow, blue, and purple, Gandalf took down the metal ring on Guderian's head with various magic crystals, and said in relief: "Sure enough. Your spiritual power has already reached the level of a tenth-order mage from an eighth-order mage, and it has only been half a year!" Gandalf said and took out a piece of parchment from his waist pocket and threw it to Guderian and continued: "This is my improved Archmage meditation method, which is more suitable for those of you who control blood. It can make your use of mental power more precise. However, there is no difference between the growth of spiritual power and general meditation methods, and whether or not spiritual power can continue to grow depends on the individual's qualifications. ”

“...... Master, isn't it ...... to study?" Guderian asked, after roughly glancing at the parchment, then putting it away.

"It's not very mature yet...... I'm going to have to let you experiment with it...... Hey, hey, hey," Gandalf smirked.

"......" Guderian was speechless.

"Wait, I've carved out a reverse circle. Since it is possible to use the method of transforming into a lich to improve into a magic circle that passives mental power, then reverse can also convert the passivated spiritual power into spiritual power that can communicate magical power. Of course, don't worry, the circle I portrayed is a simplified version, the transformation is not permanent, once you leave the guidance of the circle, you will return to normal. Gandalf said as he continued to pull various metal plates from his waist bag and put them together on the floor in the tent.

"......" Guderian was still speechless.

"Natasha's condition, I also have some eyebrows, I believe that there will be a way to wake her up soon, you don't have to worry too much. Gandalf said as he assembled the circle, "The situation is becoming more and more unfavorable for us, and a decisive battle is inevitable as the weather warms up. I must strive to overthrow the method of controlling the blood in the shortest possible time, so that our high-end combat power will not be too unbalanced with the enemy. For half a month, on the way to withdraw the team, I joined forces with several mages to deduce the future, and the scene in the foreshadowing was very confusing and worrying. ”

"What is the scene?" said Guderian in surprise, knowing that the mages had the power of prophecy. However, several archmages joined forces to derive, and among them, there were also mages like Gandalf who had already entered the thirteenth ring, and this was the first time I had heard of it.

"Flying steel monsters, endless starry skies, countless unknown creatures...... It's all vague fragments that we can't connect into a complete event. Gandalf laid out the metal plates, and then inserted pieces of magic crystals into the holes left by the various lines carved into the metal plates.

"......" Guderian couldn't help but think of what Alice said, that the earthlings were being chased by unknown enemies...... Gandalf: The events they foreshadowed had nothing to do with the fighting that was taking place on the continent?

"Alright, you go to the center of the circle and sit cross-legged, and then concentrate your mental energy and try to sense the magical elements around you. Gandalf stepped out of the circle of metal and said to Guderian.

"Good. Guderian did as he was told.

After Gandalf sat down in Guderian, he activated the circle. I saw that the lines carved on the metal plate and the inlaid crystals burst out with white light in an instant, enveloping Guderian in it, and then a layer of pale green light gradually overflowed from Guderian's body.

Guderian felt as if he was lying in a vast ocean, and every drop of water in the ocean was filled with joy. This is magic? Guderian caressed the waters curiously, and the waters were surprisingly obedient to Guderian's touches. Guderian remembered what he had heard about Fortan Ullis teaching Natasha those low-level necromantic spells, so he involuntarily guided these seawater waters to form various shapes and fill them in the spiritual power template he constructed, and then vibrated the spiritual power to cause these seawater waters to resonate - Gandalf's vision was neutral, and he saw various low-level necromantic spells flying out of Guderian's body. For a while, there was a burst of chickens and dogs jumping in the camp, and the camp tent was also torn open and dissolved by various rays or acids.

"Stop, stop quickly......" Gandalf said angrily as he threw out various spells to neutralize or resist all kinds of low-level necromantic magic shot from Guderian's body, he was worried that Guderian would destroy the unknown metal plate he had so hard to carray.

Guderian stopped in the ocean and heard Gandalf's voice, so he stopped sensing and opened his eyes.

"Huh, Master, what's going on?" asked Guderian a little strangely as he watched the cold wind pour in through the ripped tents and make a mess of Gandalf's beard and hair.

"Huh, boy, you've done a great job!" Gandalf walked over to close the circle, then pushed Guderian away, carefully examining the metal plates, and continued, "It's okay, it's not damaged. ”

Guderian stepped out of the circle and looked around the broken tents and uneven circles, and realized what had happened when he saw all the remaining traces of necromancy. So he excitedly said, "Could it be that this is the necromancy I cast?!"

"! Nearly ruined my metal plates. Boy, where did you learn these low-to-mid necromantic spells?" Gandalf asked as he disassembled the metal plate and put it away.

"I heard it when I was underground, when Master Fortan Ullis was teaching Natasha. Guderian said honestly.

"No wonder. I mean, how can you kid know these traditional necromancy. That mastery of traditional sorcery was truly legendary before he was transformed into a lich. Gandalf was relieved. Since Guderian and Natasha returned from the underground and told the story of Fortan Ullis, Gandalf's ill feelings towards the lich have decreased, and the fact that he saved Guderian once before has made his own life and death unknown (Guderian knew that the lich had been resurrected, but others did not), which made Gandalf have a good impression of the lich. At the very least, the crowd will no longer be hostile to the Lich. What's more, the Lich Notes that Guderian brought back gave Gandalf a breakthrough in his research.

Guderian activated his mental power again when Gandalf checked and put away the metal plate, but he was unable to break through his physical body and sense the sea of magic. So Guderian could only check himself, well, nothing had changed.

"It seems that I am on the right track. Guderian, you immediately go to the dragon guard and select ten people, and we will immediately experiment. Let's see if we can blunt the mental power. Take that set of spiritual power detection devices, the spiritual power must be at or near the level of a seventh-order mage, and the explosion of physical strength must be at or near the power of the three-ring fireball. Voluntarily, of course. Hey. Gandalf threw the psychic power detection device in front of Guderian and continued: "I'll go and prepare the magic circle, and bring it to the marshal after the selection is made. I'll be waiting for you there. With that, Gandalf left the dilapidated tent full of excitement and anticipation, leaving only Guderian speechless.

Guderian looked around after Gandalf left, then went out of the tent and called a few soldiers to move the psychic device outside his tent. Guderian then instructed the soldiers to go and ask Achilles to gather all the lieutenants.

A quarter of an hour later, more than ninety lieutenants, along with Achilles, gathered outside Guderian's tent. No one knew what their general was going to say when they summoned them, after all, Brigadier General Achilles was doing the work every day. When it comes to training, it's not the right place. Everyone waited with curiosity and doubt for their general to speak.

When everyone had gathered, Guderian shouted to his tent behind him, "Master Annella, come out." "On weekdays, after taking care of the affairs of the mage group, Anvila will take care of Natasha in Guderian's camp. This would have required Avella to operate the psychic device...... Although Guderian knew how to operate that thing, his spiritual power was not able to communicate the magic element, and if something leaked, wouldn't it be a joke.

Everyone had already seen the strange device around Guderian, and only a few people knew about it, but they were still puzzled about what Guderian was going to do. This made Guderian call out Master Anvira again, which made the people who were already puzzled even more confused.

"General. Annella left the tent in a black cloak and stood beside Guderian obediently.

"Well, you can help me test the mental strength of these lieutenants in a moment. If someone has reached or approached the seventh order, write down the name. If you are qualified to learn meditation, write it down as well. Guderian said.

"Okay. Avella listened to Guderian's words, looked at the device on the side, and then fiddled with it.

"I'll tell you something. Guderian took two steps forward and said loudly to the lieutenants: "Your Excellency Gandalf's research on blood control has made a breakthrough, and someone needs to be experimented." There are two conditions: first, the spiritual power is at or close to the level of a seventh-order mage, and second, the explosion of physical strength is at or near the power of a third-order fireball. Now, those who are not willing to accept the experiment are asked to withdraw themselves without any punishment. ”

After Guderian finished speaking, he quietly looked at the crowd.

After listening to Guderian's words, everyone's eyes lit up with anticipation and excitement. Guderian waited for about two minutes, and seeing that no one had withdrawn, he continued: "Next, you consciously line up to be tested by Master Anvila's mental power. Experiments are unknown, so please consider them carefully. After saying that, he waited for a minute or so, and seeing that no one had withdrawn, he walked aside and nodded to Avira, signaling that he could start.

So, in anticipation and excitement, everyone lined up and walked towards Annella one by one......
