At night, there was a dead silence, the outside of Longwu City was extremely quiet, the moon in the sky appeared in the clouds from time to time, sometimes hiding, the sound of the undead army had disappeared for almost a day, and the students on the city had already been replaced by the soldiers of the Mu family army.

"Whew!" A strong wind suddenly rose outside the city, and the dark clouds gradually swallowed up the last trace of moonlight, and bursts of killing air came from the mountains and forests outside the city, and then a burst of neat footsteps echoed on the ground.

"The army of the undead is coming!" Suddenly someone shouted at the top of the city.

"Be on guard! Alert! A guard ran and shouted at the top of the city, reminding all the soldiers of the Mu family army to take precautions.

"Boom! Boom! Boom! The footsteps were slow and heavy, from far and near, from blurred to clear, listening to everyone's ears, but arousing a trace of tension in their hearts.

Thousands of kilometers outside Longwu City, a large area of black oppressive things was slowly moving, countless points of green light flickered suddenly, and suddenly hidden, and a cold aura slowly rose in people's hearts.

"Magic Cannon Ready!" Principal Long personally went into battle to command, Mu Xiaotian replaced all the people who operated the cannon with the Mu family army, a unit with military literacy, and it was a neat thing to act, as soon as the words fell, everyone had not only loaded the magic cannonballs, but also the people who operated them were covered with battle qi on their palms, and placed them on top of the six-pointed star pattern, ready to attack at any time.

The army of the undead slowly approached, but they didn't mean to charge, they just kept moving at a constant speed in the direction of Longwu City.

"Brother Mu," Principal Long asked Mu Xiaotian when he saw this, "Judging from your years of battlefield experience, what do you think these undead army want to do?" ”

Mu Xiaotian stroked his beard lightly, a trace of doubt rose on his face, and after pondering for a moment, he spoke: "They are waiting for an opportunity." ”

"Waiting for a chance?" Principal Long was a little puzzled, "What opportunity are you waiting for?" ”

"A great chance to attack!" Mu Xiaotian said again.

Principal Long was even more confused when he heard this, and Mu Xiaotian instructed a guard officer behind him: "Without my order, no one is allowed to act rashly!" ”

"Yes!" The officer was ordered to retreat.

"Brother Long," Mu Xiaotian glanced at the magic cannon, and then said to Principal Long: "Don't use the magic cannon for the time being, I feel that this attack, they came prepared, and it is definitely not as simple as what they see in front of them." ”

Principal Long nodded thoughtfully, and then ordered in a loud voice, "The gunner has withdrawn his battle qi and is ready to stand!" All the gunners put the battle qi in their hands into their bodies.

At this time, the crown prince Long Yi and Nishizawa walked up to the city with excited faces, "Headmaster, is the undead army attacking again?" Long Yi couldn't help but ask.

Principal Long didn't speak, just pointed to the outside of the city, Nishizawa quickly ran to the city wall, opened his eyes, and couldn't help but say excitedly: "Great! It's finally here again! After that, he turned his head to Long Yi and said, "His Royal Highness the Prince, let's compete again?" ”

"Compare to compare!" The prince won a victory, and at this time his fighting spirit and confidence were very sufficient, and as he spoke, he ran to the city wall, ready to jump out of the city again to kill.

"His Royal Highness the Crown Prince!" Mu Xiaotian's face was anxious, and he hurriedly ran to Long Yi's side, "His Royal Highness the Prince, don't go out of the city to fight!" ”

"Why not?" The prince was a little unhappy, "Didn't you see the scene when the prince killed the enemy in the morning?" It's no problem to clean up the undead! ”

"Although the prince's bravery was seen by the old man with his own eyes," Mu Xiaotian explained, "but the way the undead army attacked a little differently tonight, there must be some conspiracy, and the old minister is afraid that the prince will fall for the enemy!" ”

"Afraid of what?" The prince said proudly, "Don't say that the strength of this prince is far superior to those undead, even if it is not as good, there are magic cannons that can break the siege." ”

"Yes, Master Mu," Xi Ze was bent on winning back a game, so he interjected, "What's more, Principal Long's Shishen White Light Tiger is not only the nemesis of dark creatures, but also has the power to return to the sky, with him, what else is there to worry about?" ”

"This ......" Mu Xiaotian couldn't find a reason to refute for a while, and the crown prince was in a high position, so he couldn't be the master of the house at this time.

"Don't do this, that," the prince was a little impatient, he was afraid that Mu Xiaotian would be verbose again, so he said: "This time we are only ten minutes apart!" After saying that, he ignored the other party anymore, jumped off the city wall, and Nishizawa stretched out his arms and walked away.

"Magic Cannon Ready!" Mu Xiaotian ordered again, "If there is anything abnormal, fire immediately!" ”

At the same time, Mu Yun's room flashed with colorful lights, and she kept chanting various spells in her mouth, a red skeleton appeared in the room for a while, and a blue skeleton appeared in the room, and the colorful skeletons were summoned by her one by one, and also scared Xiao Hei and Zai to hide in Mu Yun's arms and scream for a long time before slowly stopping to chant the spell.

The Blood Wolf Emperor lay on the ground without saying a word, and showed great disdain in his heart for Xiao Hei and Zai's reaction, "What a fuss!" He muttered to himself.

Mu Yun happily ran to each skeleton to take a look, and looked down, as if admiring a work of art, "Wow, it's so beautiful!" Mu Yun looked at his creation and couldn't help but praise.

"Master, you have such a strong taste!" Xiao Hei complained, "I actually said that the dead man had a beautiful skull. Hearing this, Tsai also nodded his little head desperately.

"Ugh!" Mu Yun realized that he was a little perverted, so he stuck out his tongue in embarrassment, "Hehe, it's the first time people have made these things, I'm a little curious and excited." ”

After Mu Yun finished speaking, he no longer paid attention to the two living treasure god pets, and examined the skeletons one by one, "Wind, fire, water, earth, darkness, light, space, all together!" Mu Yun looked at the seven skeletons excitedly, and then slowly recited the spell on the summoning secret method.

As her yin and yang spell was pronounced, the seven skeletons began to move slowly, moving back and forth around the room, their jaws still biting together and making a permeating "click" sound.

"Raise your hand!" Mu Yun suddenly ordered. The seven skeletons raised their arms at the same time, "Down!" She gave the order again, and the skeletons did it again.

"Hey, hey! Playful! Mu Yun had a lot of fun, and seeing that they were very obedient, he ordered again: "Jump!" The seven skeletons immediately jumped, "Click, click!" The sound of the joints crashing filled the room, and the three gods could see their heads swaying up and down at the same time with the movements of the skeletons.

Suddenly, when five of the skeletons landed on the ground at the last time, the "Kababa" was scattered into broken bones, and Mu Yun hurriedly ordered: "Stop!" The two remaining skeletons stood still.

The remaining two skeletons, one is white of the light system and the other is black of the dark system, Mu Yun squatted down, pulled the broken bones on the ground a few times with his hand, looked at the only two skeletons left, and said suspiciously: "Why aren't those two broken?" ”

"I know this!" The Blood Wolf Emperor spoke, "It must be the master that the light and dark energy in your body is the most powerful, so the undead warriors of these two lines summoned are also the most powerful. ”

"Yes, master," Xiao Hei replied, "that's what Mom told me. ”

"Hmm!" Mu Yun nodded, and then said happily: "Anyway, I succeeded in two." ”

"Well, when the army of the undead comes to attack again at noon, you can try the power of the two of them." Xiao Hei is also very curious about the attack power of these two newborn monsters.

"Oops! When is it now? Mu Yun was fascinated by practicing the undead summoning technique, and only then did she remember Principal Long's instructions, she ran to the window to look at the sky, and shouted, "It's over!" It's actually night, and I don't know what happened to the road over there? Little Black, Boy, Blood Wolf, Let's go! ”
