As soon as the sky was bright, the horn of vigilance sounded on the gate tower of the Dragon and Tiger Pass, and a large area of dim sand and dust fog suddenly rose in the mountains and forests in the distance outside the city, and the dust and fog flew all over the sky, and it was not clear what kind of terrible enemy was hidden inside, but there was a faint tremor on the ground, which made people feel as if there was a behemoth approaching the Dragon and Tiger Pass.

"Knock knock!" The sound of the earthquake trembling became clearer and clearer, and the guards guarding the city felt that the city walls under their feet were shaking with it, and their feet couldn't help but be shaken and jolted, and even the magic cannon on the head of the city was also shaken and slid backwards.

Mu Yun meditated in the big tent all night, at this time the spirit was high, and she felt the abnormality outside the gate early, she closed her eyes slightly, calmly drank the tea in the tea cup, and her spiritual power gushed out like a tide, enveloping dozens of miles outside the Dragon and Tiger Pass.

A black shadow flashed behind Mu Yun, and Xiao Hei, who had turned into a human form, suddenly appeared, "Sister, there seems to be a very powerful demonic beast in the underworld army this time," Xiao Hei walked to the door of the big tent, lifted the curtain and glanced at the city, "Those defenders of the Dragon and Tiger Pass seem to be a little restless, aren't they affected by the coercion of the demonic beast?" ”

Hearing this, Mu Yun slowly opened his eyes, looked at the handsome and tall little handsome guy in front of him, and couldn't help but show a smile, and said, "Xiao Hei, what's the matter, can't stay in the two-dimensional space?" Want to come out and join in the fun? ”

"Hehe," Xiao Hei put down the curtain, walked in front of Mu Yun with a cute look, and said coquettishly: "Sister, don't I just want to come out to breathe, and by the way, I will help my sister share some of it." ”

"Okay, I know you feel sorry for your sister," Mu Yun gently touched Xiao Hei's head with his hand, "I just have a task to be handed over to you, and in a while I will use the undead warriors summoned last night to face the enemy army, you take the opportunity to find out the reality of the enemy army, remember not to fall in love with the battle, and come back immediately after finding out the situation!" ”

"Ah," Xiao Hei made a reassuring gesture, "this is not the first time I've been on the battlefield, so just sit back and wait for my news." With that, his figure suddenly became smaller, and he stepped out of the tent from beside the curtain, and after a crisp dragon groan, Xiao Hei swept into the sky.

Mu Yun slowly stood up, a thick black mist overflowed from the palm of her right palm, she silently recited the ancient incantation in her mouth, and after a while, her eyes suddenly widened, and the black mist in the palm of her hand was thrown into the air, "Poof! With a muffled sound, the black mist made a slight air explosion in mid-air and vanished.

"Mu Yun, boss!" There was a loud cry of Zhan Tian and the black wolf outside the tent, and after a while, the two broke into the big tent one after the other, Zhan Tian saw Mu Yun's calm and relaxed appearance and couldn't help but shout anxiously: "Hey, my eldest lady, the enemy will attack the city soon, why are you still like a nobody?" ”

The black wolf said, "Yes, boss! There seem to be a lot of big guys coming outside the city, and I'm afraid our defenses won't be able to resist it! ”

Mu Yun put down the tea cup in his hand, smiled faintly at the two reckless men, and said, "Two big brothers, don't be impatient, I have already sent troops to resist the enemy, I believe it won't be long before we will see you." ”

"Boom! Thundered! At this moment, a roar suddenly sounded outside the city, like thousands of troops galloping on the earth, but strangely, the sound gradually became blurred from near to far.

The black wolf and Zhan Tian rushed out of the big tent in amazement, and one flew towards the city gate tower, and when they opened their eyes, the two couldn't help but be taken aback.

"Hahaha, good you Muyun, you really have you!" Zhan Tian shouted with joy, "I actually turned all the Underworld Holy Warriors who died in battle yesterday into an army of undead!" ”
