In the early morning of the next day, the sky had just revealed a trace of fish belly white.

In the No. 2 gravity training room of Dongwei Mansion, the sound of fierce fighting shook the roof tiles, and the two figures were still moving at an extremely fast speed under fifteen times the gravity.

"The strength of the sword should be strong but not too strong, not too straight and not too weak, a sword must be swung without hesitation, the speed must be fast, and it must be fierce! Hurry up, the action is sharper! ”

The one who spoke was a middle-aged man in the uniform of Dongwei Mansion, his name was Donghyuk forty-six years old this year, a man who made Lin Yu completely incomprehensible, and he was Lin Yu's martial arts teacher, even though Donghyuk never promised to accept Lin Yu as an apprentice, but he was very dedicated when teaching Lin Yu.

Dong Hyuk could see Lin Yu's talent in swordsmanship, especially Lin Yu's mature fighting skills at such a young age, which was also unexpected by him, of course, in his opinion, Lin Yu's talent was enough, but he was still too young, and he did have deficiencies in some aspects.

Lin Yu nodded slightly, his habit of using a sword rarely used an extremely sharp way to confront the enemy head-on, especially in life and death battles, many times the way he won was not by the sword in his hand, but by his body.

Lin Yu understood what Donghyuk meant, today's class is training swords, not body techniques, and Lin Yu must distinguish between priorities and priorities.

With a deep breath, Lin Yu held his sword and met it head-on, the corners of Donghe's mouth rose slightly, just standing in place, and only then did he make a move when Lin Yu approached.

Lin Yu's movements were very fast, and the point of the sword was either Dong He's vital point or his fatal point, although Dong He took them one by one and was very relaxed, but he couldn't help but feel a chill in his heart.

Although Lin Yu's sharp attack was a little rusty, among his peers of his age, there was definitely no second person compared to Lin Yu. And Donghyuk knows very well that if it weren't for the fact that he was a few years older than Lin Yu, his ability was stronger than him, and if he was at the same level as Lin Yu, he was afraid that he wouldn't be able to take a few tricks directly.

Even if neither of them used Star Source Power at this moment, after all, the difference between the realms between the two at the moment was too great, not to mention that Dong He's physical ability had already surpassed the level of his peers, and it was indeed a little difficult for Lin Yu to bargain in his hands.

After a few moves, Lin Yu's moves were not suppressed, and it was difficult for Lin Yu to use his own skills to attack, and it was difficult to ask for a few tricks in Donghyuk's hands.

After this period of training, Rao is Lin Yu also had to admit that Qi Xuankun's eyes were ruthless, Donghyuk's training was obviously aimed at Lin Yu, his tactics were similar to Lin Yu's, and his strength and speed were much stronger than Lin Yu.

Even in the same rank, Lin Yu is difficult to win.

The high-intensity training after a whole day can be said to have made everyone, including Lin Yu, less skinned, and everyone was exhausted on the bed in the end.

Time flies, especially during training, and everyone expects it to pass quickly.

However, this day may be a day that the people of the Great Wall in the entire Donghua Federal Region will never forget for the rest of their lives.

The deafening sound of sirens echoed throughout the Great Wall, and everyone here had been on guard since the morning, the black Star Source armor emitting a chill glow in the scorching sun.

"Miao Miao, why are you here!"

The second defensive line of the Great Wall, although it is the second, is the most cutting-edge front of the entire Great Wall.

"Me."

Qi Miao bit her lip tightly, looking at Lin Yu with a serious face in her eyes with tears in her eyes, but she didn't know how to say it at the moment.

"Alive, come back alive."

Qi Miaomiao looked at Lin Yu solemnly, she hoped that he in front of her could give her an answer. But for Lin Yu, he had no choice.

"Old wolf, Dewey took Miao Miao down, and the others continued to stay at their posts."

Lin Yu turned back indifferently, and two young men wearing Xingyuan battle armor stepped forward, although they were reluctant, but after all, they still couldn't violate Lin Yu's orders.

Qi Miaomiao's tears fell, she could have left with the other civilians yesterday, but she didn't.

On the iron wall of the Great Wall, countless laser heads popped out of the hidden hidden grid, and the power grid composed of electric currents spread out three hundred meters outside the iron wall of the Great Wall, and the voltage of 300,000 watts burst out with countless sparks.

"Boom, boom, boom!!!"

The yellow sand in the distance is long, and everyone in the Great Wall can clearly feel the shaking of the earth.

Qi Xuankun's central headquarters, in front of the three large screens, flashed countless red dots, some large and some small, almost filling the entire screen.

"The seventh-level domain demon legion, the energy radiation range is thirty kilometers, and it is expected that at least two three-level demon generals will exist."

"The number of domain demon legions detected, the number is estimated to be seventy-five thousand six hundred and thirty, of which the number of domain demons at the demon yuan level has reached six thousand."

"The Domain Demon Legion is still three kilometers away from the iron wall, and there are still two kilometers left......."

The sirens in the command room were blaring one after another, and everyone was on standby.

"The Domain Demon Legion broke through the first blockade line and approached the power grid area!"

"Immediately adjust all laser cannons, as well as the star source cannons, and order all to fire freely!"

Qi Xuankun immediately gave an order, and the herald in the command room immediately gave orders to all the commanders and combat units.

Outside the Great Wall, a black oppressive storm struck, and countless various domain demons and star beasts rushed towards the Great Wall in a swarm, and the weapons that appeared on the iron wall seemed to be just decorations for them.

"Boom!"

A laser beam the thickness of a telephone pole flew out, only to hear a roar like the sky and the earth cracking, and a crack appeared on the domain demon front, but soon, all the subsequent domain demons surged up one after another.

The domain demons rushed forward frantically, and countless domain demons turned into ashes under the coaxing of the cannon fire, but these bloodthirsty beasts retreated meaninglessly, and rushed towards the Great Wall frantically.

Hundreds of thousands of watts of power grid block, but it also has no resistance to the madness of the Unknown Domain Demon.

Inside the Great Wall, the soldiers who are ready for hand-to-hand combat at any time can't help but have cold hands and feet at this moment.

These people have been outside the realm all year round, and it is not that they have not fought with the domain demons, but no one seems to have seen such a large-scale domain demon.

The distance between the domain demons and the second line of defense of the Great Wall is getting closer and closer, and even under the continuous bombardment of laser cannons and star source cannons, it seems that only less than half of the domain demons have been wiped out.

The number of domain demons displayed on the display screen had been sharply reduced from 70,000 at the beginning to 40,000, but this number was still terrifying.
