Fortunately, the torture did not last long. Karthas had just run a few steps, and a shocking explosion came from the direction of the battlefield. The air waves caused the two of them to throw seven or eight feet away, and then they hit the ground heavily. The explosion crushed the rocks on the ground and swept into the sky. It actually caused a "stone rain". Fortunately, the two were still a distance from the center of the explosion, and the larger stones could not fly so far. Even so, there were still several fist-sized stones roaring on Feili's back. The severe pain made him look dark and he almost fainted.

"Ahem, wow—"

After recovering from the dizziness, Feiri immediately vomited blood onto the ground. He supported the mud with his hands and struggled to sit up. He felt his chest hurt with a burning pain, and his ribs were probably broken, and even one or two of his teeth seemed to be loose.

But this was not the worst. He felt that the originally stable and orderly magic net was already in chaos, with various energies rushing and entangling each other. This made him, the magician, extremely uncomfortable and made him unable to heal his injuries. In this case, he would know if he would turn into an earthworm or a toad.

"What a bad luck!" He angrily threw away the potion bottle that was approaching his mouth far away, resisting the pain and looking back, and it was revealed that the bushes that had just been hiding had been razed to the ground, and the center of the explosion further away was a completely hellish scene.

In the burning fire, huge smoke and dust reached the sky, leaving only a piece of gravel and broken wood on the ground. The terrifying crack spread on the ground like a spider web until a huge deep pit in the center. I don’t know how Ilminster and Xinbu are now. In short, I have no energy to care about them at the moment. Fortunately, the defenders of the Arctic Port seemed to be shocked by this scene and did not come out to pursue...

"Hey, when is it time? Have time to stay there? Get up quickly!"

A hoarse voice sounded in his ear like thunder. Feili, who was thinking about it, came back to her senses and found that Karthas was yelling in the ear. Although the female professor also became dirty in the explosion and his clothes turned into strips of cloth, she seemed not to be hurt too seriously, and at least she was still flexible in activities.

"Cough cough!" Feili had just moved her body, and another severe pain in her chest, as if the broken ribs poked into her lungs. He coughed and spitted out a mouthful of dirty blood and half of her broken teeth. In the end, she gave up her efforts and collapsed weakly on the ground.

"I'm really sorry, I can't seem to move...Ahem!"

Karthas hesitated for a second, finally turned around and squatted down, whispering to Feili. "Listen, Xiao Feili, climb onto my back."

“…”

"What a fool, little fool! The magic nets in this place are all messy. What else can I do except escape back with two legs? Or do you prefer me to mop the floor?" The female professor turned around and glared at him. She said angrily.

Feiri's neck shrank and he quickly crawled onto Kalsas's back.

The female professor stood up with her thin body and took big steps towards the military camp, without any difficulty. The only thing that surprised Feili was that the female professor's body seemed to feel the heat at all. Although she was also panting due to intense exercise, the white frost on her head and eyebrows showed no sign of melting.

However, Feili has not yet had the heart to explore such a small problem. The thinking loop in his mind was completely filled with the amazing explosion just now.

"His Excellency Kalsas, you have worked so hard. You have to carry me after being injured. It's so embarrassing." When the pain in his chest eased a little, he tried to start a conversation.

"Don't be so polite. It's my responsibility to speak, and I'm going to bring you to danger. I'm really sorry! When I run out of this dangerous place, I will help you treat it well." Karthas responded casually without looking back, his feet still running at full speed.

"Where, you taught me a very vivid lesson. I should be thanking you. Oh, by the way, what happened to the explosion just now?" After a few polite words, Feili finally got to the point.

"That explosion? Ilminster was useless to reduce the magic circle to reduce the vibration of the magic. He directly activated the earthquake technique. The magic net here could not withstand such overload abuse at all, so he naturally collapsed!"

"Ah? I thought that only gods could destroy the magic net at once!"

"If it is in the Feren continent, the magic net is indeed not easy to destroy. But the problem is that this is not the Feren continent!" Karthas said, "Any magic with greater power and wider coverage will take to cast it, and the higher the requirements for the magic net to bear. If the magic net in the Feren continent is solid land, then the magic net here can only be regarded as an ice layer with uneven thickness, and casting magic is similar to walking on the ice layer. The higher the magic level, the greater the pressure on the ice layer. If the low-level magic is an ants, the intermediate magic is a traveler, and the advanced magic is a knight, then the legendary magic is almost equivalent.

Or an elephant! Can the ice layer carry such weight?"

Although Kalsas' metaphor is very vivid, Feiri still has a mistake.

"But... didn't he successfully cast the meteorite magic at the beginning?"

"Yes, but this spell failed in the end because of interference, so the crazy magic power generated created huge trauma to this magic net. Ilminster did not even move the place, and cast the next magic. What's the difference between passing a dragon on the ice layer that had already stepped on the cracks?"

"Oh, that's right. Then if he uses earthquake techniques first, wouldn't he be able to avoid such a bad situation?"

"I'm afraid it's not optimistic."

"Um?"

"Because it is necessary to search for weak spots in the earth's crust, it takes much longer than meteorite magic, but it is easier to crack earthquake magic than meteorite magic!" Karthas explained, "The magic array of earthquake magic must go deep into the strata and firmly adhere to the rock or soil layer. As long as people on the ground detonate a large amount of explosives at an approximate location, causing the formation to shake one step ahead; or allow the Mithra fog that can isolate the magic net to seep into the ground, the precise magic array will be invalid, and then cause violent magic shocks..."

"The explosion happened just like before?" Feili blinked and asked back.

"It should be almost the same, it shouldn't be that intense, but I haven't seen the specific ones before." Karthas thought for a while, and answered with some uncertainty, "After all, the magic of earthquake technology is just a catalyst, and the real power depends on the cracks of the plates and lava in the formation. Otherwise, wouldn't it be equivalent to causing an earthquake by itself?"

"According to your inference, it seems that all legendary magic has doors that can be easily cracked.

”

"That may not be necessary, it depends on the place and time of casting." Karthas made a statement and gave a conclusion, "In short, legendary magic has very high requirements for magic nets and environment, and it cannot be used casually in any occasion, otherwise there will be a great risk of failure. Otherwise, why are the famous magic battles in the main material plane mostly born in strong seclusion places, famous magic academies and magic cities, cults and evil mages bases, and monster nests**? It is because the magic nets in those places have very good stability!"

"...So, legendary magic is like the ancient heavy cavalry. Although it is powerful, there are not many places to play, right?" After thinking carefully, Feili tentatively put forward his own opinion.

"That's about it. Measuring the value of magic is not just about comparing the power of magic, but comprehensively considering their advantages and disadvantages. A truly excellent magician should clearly understand the effects and defects of each magic, and choose the most appropriate time to use each magic in the most appropriate place, so that they can't replace it with other things. Those who cannot do this, or forget this after gaining strong strength cannot be considered a truly successful magician!"

"...In other words, as long as you know how to use every magic in the right place, a magician with a lower level may also defeat an opponent with much higher level than his own?"

"That's right." Karthas nodded in praise, "But one more thing to add is to be good at using external objects, such as firearms, traps, terrain, weather, etc. Whether it is fighting or daily work, any factors in it will affect the final result. Magicians who only focus on improving the power of magic are all lame men with a narrow margin. You must remember that the reason why magicians are powerful is not only power, but also skills and mind!" She raised her hand and poked the sun's forehead, with a very solemn tone.

After hearing this, Feili was silent for five minutes before speaking hesitantly, "Thank you very much for your teachings, Karthas...teacher?" he said hesitantly.

"Oh hehehe! Xiao Feili, are you trying to take me as your teacher? I have very high requirements for students!" Karthas couldn't help laughing, and looked back at Feili, his pupils were full of jokes.

"If I could get guidance from a senior expert like you, of course I would be very grateful." Feili, who was lying on the back of the female professor, squeezed the other party with a small smile, and then smiled, "Although I am afraid I am not qualified to say this now, I still want to tell you that even when it comes to the end of my life, your teachings tonight will still be remembered in my heart. Thank you!"

"Oh hehehe! Cute little guy, I'm looking forward to your future performance!"

...

Under the starry sky at midnight, the woman with broken clothes was carrying a thin wounded man on her back, looking around at the thicker night around her. A string of hearty laughter echoed in the howling cold wind. And on the distant horizon ahead, there were gradually revealing orange-yellow ***s.
