The upper echelons of Kurast, Kasha and the others and all the Rog Liberation Army were all looking in the direction of Cui Vanke, and at this time, everyone's eyes were full of enthusiasm and fear, just because of the huge rotating ball of light that annihilated everything.

The horror was because of the terrifying and devastating power of the orb of light, and the frenzy was because of the terrible power that came from their beloved majesty.

As the annihilating orb grew larger, a figure flew out of the air and quickly returned to them.

Trevac is 17 kilometers long from east to west and 9 kilometers wide from north to south, and the vortex of wave energy particles erupts in the hate cage to the east, and the radius of 3 kilometers to the east of Trevank City has become a huge round crater.

Yes, against Mephisto, Yang Yifei did not fight it head-on, but used a wave energy particle bomb.

Because if he wants to completely annihilate Mephisto's soul, only this thing can do it among the means that Yang Yifei has mastered, and if he wants to do it once and for all, he must use it.

Since it's going to be used in the end anyway, why bother fighting it again?

So after he used Klim's will to open the seal of the hatred cage, he ordered the army to retreat, and Nataya and the others thought that he was going to use the squad siege tactic again, who knew that Yang Yifei actually let them retreat together.

Kasha and Flavi were naturally reluctant, but Yang Yifei explained that he was preparing to use the ultimate nirvana, and once this method was used, everything within a radius of three kilometers would be destroyed, and the two of them reluctantly withdrew from Cui Vank with the large army.

Yang Yifei entered the cage of hatred alone, and he didn't go down, not even fighting the demons, he used teleportation all the way, and went directly to the central area, where he dropped the wave energy particle bomb.

Then he returned to the entrance, took out the remote control, pressed the start button, and flew out of the killing range of the wave energy particle bomb at supersonic speed.

The diffusion speed of the vortex of wave energy particles is 100 meters per second, the normal flight speed of Yang Yifei is 1.5 times the speed of sound, that is, 510 meters per second, and the maximum flight speed is 5 times the speed of sound, that is, 1700 meters per second.

The third layer of Mephisto's Hate Cage is 200 meters underground, and naturally cannot escape the 3,000-meter radius of the Wave Energy Particle Bomb.

In the vortex of wave energy particles, even with Mephisto's protective energy, it only lasted for seven or eight seconds before it was completely wiped out, including the soul.

After killing Mephisto, Yang Yifei did not delay much, and immediately ordered to return to the Kurast seaport to rest.

Although helicopters are now an infinite source of energy, he is reluctant to use helicopters for long-distance transportation until the problems of wear and tear of parts and aging lines are solved.

Only Black Hawk helicopters can carry personnel, while Black Hawk helicopters can carry only 16 people, and 20 can only carry 320 people in one trip.

There are more than 8,600 people here, and they have to fly 27 times, covering a distance of nearly 30,000 kilometers.

Moreover, it takes about 6 hours to run a round trip, and it takes nearly a week to complete 27 runs, and the wear and tear caused to the helicopter cannot be counted at all.

Now that the demons on the marching route have been emptied, they only need to hurry, and they can rush back to the harbor in a month at most, so it is better to let the soldiers work hard, and it can also play a role in long-distance training.

……

More than a month later, the troops successfully returned to the harbor, and Yang Yifei organized a grand celebration party, which lasted for three days, and all the soldiers and civilians were immersed in the joy of the liberation of Kurast.

During this period, the high-level alchemist Omars and the magic blacksmith Hera Tieli announced that they would join the Republic of Rog, and Yang Yifei was naturally very happy about this, and two more generals were added to his magic technology research.

Yang Yifei immediately sent Flavi to fly the helicopter himself and sent them to Lu Gain to join Kane's research team.

Today's magic technology research team members are: Decca Kane, Chasi, Farah, Dragognam, Omars, Hera Tieli, and the lineup is quite strong.

In particular, the magic arrays and runes they knew were different, and when they were combined, they greatly enriched the rune and magic circle database of the Rog Republic.

Now their research direction is to research the magic circle or rune that can be solidified on various magic machines, so that the machinery has the effect of "never wearing".

Such runes exist, and some equipment in the dark world has the characteristic of "never being damaged", that is, unlimited durability.

There is also a way to restore durability 1 in how much time, to put it simply, this rune can allow the wear and tear of equipment to slowly repair itself.

No matter which of these two runes is studied, Yang Yifei's helicopter and chariot car will never need to be maintained, either they will never wear out, or they will recover on their own.

After the celebration party, the Rog Liberation Army began the great cause of logging and shipbuilding in full swing, and the citizens in the harbor worked one after another, and tens of thousands of people helped the Rog Liberation Army build ships, and they did not need to be paid, just take care of the food.

This time to Harogas, they will sail north along the Twin Seas, sailing more than 2,000 kilometers to the end of the Twin Seas, which is also the junction of Kegistan and Harogas.

The shipbuilding work lasted for three months, and with the concerted efforts of tens of thousands of people, all the ships that could carry 10,000 people were completed, and there were more than 80 large ships.

During these three months, there were also some events that made the citizens of the seaport of Kurast angry.

It was Hakan the Great of Kegistan, who sent envoys and troops to recover Kurast after the demons of Kurast were wiped out and the city of Kurast was recaptured.

This naturally aroused the wrath of the citizens of Kurast, and when the demons broke out, Hakan the Great, with his army and wealth, left the people and ran to Kartim himself.

Now that the Luoge Liberation Army has eliminated the demons, they actually want to come to pick peaches, and tell Yang Yifei that they will rule the Eastern and Western continents and coexist peacefully, and they also sent generous gifts.

For this kind of brain-dead, Yang Yifei didn't even bother to speak, he left a generous gift and shot people, and the 5,000 troops brought by the envoy were naturally not happy, so they wanted to make trouble.

Any emperor with a little brain would not do such a stupid thing, and he didn't want to think about it, they had no power to resist in front of the demon army, but they exterminated the demons, is that what they can afford to provoke?

The main reason is that the number of Yang Yifei's troops gave Emperor Hakan the illusion that Kaijistan has an army of 100,000, and if necessary, another 100,000 can be recruited at any time.

And the combat troops of the Luoge People's Liberation Army are only more than 10,000 people, which makes him feel that he is qualified to negotiate conditions with Yang Yifei, and it is already very face-saving for him to rule across the sea.

After all, in the past, the three major kingdoms of the Western Continent had to pay tribute to Kaijistan every year.

However, reality slapped Emperor Hakan in the face, and the 5,000 troops were slaughtered by the Loge Liberation Army, but they couldn't even get close to each other to the range of their own bows and arrows.

After witnessing the terrible fighting power of the Log Liberation Army, the surviving Kegistan soldiers decisively surrendered, changed their flag, and joined the Loge Liberation Army.
