"Toot! Honk! Suddenly, the sound of a loud trumpet came from the top of the city, "Night attack!" There's a night attack! The soldiers at the head of the city shouted loudly into the city.

"Huhu!" Suddenly a torch lit up in the middle of the city, and the city was as bright as day.

Mu Yun and the others in the big tent heard the movement, and they came outside the tent one after another, "Report!" A guard ran to Mu Yun and knelt down on one knee and said respectfully, "Report to the alliance leader, a large number of powerful enemies have been found in the mountains and forests outside the city, and they are attacking the Dragon and Tiger Pass at full speed at this time!" ”

"Pass the order!" Mu Yun's expression suddenly became extremely calm, "Everyone is in line to defend in the city, and use all the battle qi and spiritual power to support the defensive enchantment of Dragon and Tiger Pass, and no one is allowed to go out of the city to face the battle!" ”

"Yes!" The guards were ordered to turn around and run in the direction of the city gates.

"Brother Lin, Brother Yun," Mu Yun turned to the two behind him again, "I beg you to order someone to line up the magic cannons in a vertical row, and then cast a seal on each cannon to protect them from being heated and self-destructing." ”

Lin Tianhao and Yun Chenyi glanced at each other when they heard this, then they each nodded and turned around and walked in the direction where the magic cannon was placed.

"Whew!!" Outside the Dragon and Tiger Pass, the crazy roar was deafening, like thousands of beasts roaring in unison, although the soldiers in the city were all strong warriors, but when they heard such a roar full of evil spirit, they couldn't help but tremble slightly, everyone held their breath, the sound of their hearts beating was clearly discernible, and above the ink-colored sky, dark clouds were rolling and surging, as if they were also driven by this earth-shattering roar, covering the last trace of moonlight like a tide.

"What a strong evil spirit!" General Long stood on the tower of the city gate, his eyes were blazing and staring at the front of the gate, the silver light beside him flashed slightly, and Mu Yun appeared in shape.

"Old General Long," Mu Yun said calmly, "I'm afraid there will be a tough battle tonight, but the general can rest assured, as long as you can maintain the defensive barrier of the Dragon and Tiger Pass, I can defeat the enemy in an hour!" Her face was full of confidence, and she didn't pay any attention to the incomparably powerful and numerous enemies of the underworld outside the city.

"Don't worry, Lord Mu!" Seeing Mu Yun's calm expression, Old General Long also breathed a sigh of relief in his heart, "Long swears to live and die with the defensive enchantment of Dragon and Tiger Pass!" ”

"Thank you!" Mu Yun solemnly arched his hand at him, then turned to look outside the pass, and the old general Long saluted in return, and said earnestly: "The safety of the Heavenly Dragon Kingdom is entrusted to the Lord of the Mu League!" With a wave of his hand, he beckoned several of his lieutenants to his side, and then gave a low command before leading them down the city.

Mu Yun's eyes were like lightning, and he looked straight outside the city, only to see huge black humanoid monsters constantly pouring out of the mountains and forests, they moved fast and the momentum was surging, and they were several times braver than those cursed warriors before.

"Looks like they're out this time!" Mu Yun muttered to herself, and the rich purple spiritual power battle qi on her body began to slowly overflow, enveloping her entire body, and gradually these spiritual power battle qi began to close inward again, suddenly gathering on her right arm.

"Whew!" Mu Yun exhaled a long breath, his right arm was slowly raised back, his slender and white palm slowly opened, and then he waved forward suddenly, and shouted in his mouth: "Fire!" ”

"Boom, boom, boom!" As soon as Mu Yun's shouting fell, there was a roar in the camp in the city, dozens of magic cannons fired a salvo, and the colorful magic cannonballs in the sky instantly dyed the night sky into a brilliant one, "Boom!" "With a sharp whistling sound, the shells fired lightning at the enemy outside the pass.

Everyone in the city looked up at the sky, deeply attracted by the colorful picture in front of them, and for a while they actually forgot about the crisis of the strong enemy outside the city, and their mood suddenly became relaxed.

In this way, the spiritual power and combat qi they could exert were even stronger, and the defensive enchantment of Dragon and Tiger Pass had become impregnable at this moment.
