In front of the Lu family's camp, tens of thousands of undead armies trampled the ground into dust, and countless demonic red rays shimmered in the night wind, most of the summoners had never seen this strange creature, and they couldn't help but retreat in their hearts, only the Imperial Forest Army under Lu Tianqi was a little calm.

Lu Tianshuang chanted a jerky fire-based spell in her mouth, and sacrificed a fireball with a diameter of more than five meters in the air, her face was pale, and she almost extracted all the spiritual power in her body.

"Whew!" The fireball flew forward, and was blown by the night wind, and the undead demonic beast saw the fireball attacking, and did not back down at all, "Boom! Several undead demonic beasts rushed directly into the fireball, and the fireball burst open, staining a radius of more than fifty meters with raging flames.

"Whew!" The rest of the undead demonic beasts continued to walk forward on the flames, and after a while, they trampled on everyone on the ground and extinguished them, and the several undead demonic beasts that were shattered by the fireball just now had also recovered to their original state and continued to attack.

"Brother, these creatures are immortal!" Lu Tian's face was anxious, "What should we do?" ”

Lu Tianqi frowned, pondered for a moment, and then spoke: "I have read this kind of thing in a book before, they are undead creatures, as long as there is a steady stream of dark power, then they are invincible. ”

"Shall we fight then?" Lu Tianshuang asked.

"These monsters won't appear on their own for no reason," Lu Tianqi shook his head, "Someone must have deliberately summoned them to deal with us, as long as we find the caster and cut off the supply of dark power, then it will be easy to destroy these undead evil creatures." He turned his head to a commander beside him and said, "Tell me to go down, close the gate of the camp, and no one will be allowed to fight!" Violators, behead! ”

"Yes!" The Commander bowed, then stepped back.

"Brother! Is that okay? Lu Tianshuang was a little worried, "What if they attack in?" That's tens of thousands of undead beasts! ”

"Don't worry, brother has a secret weapon." Lu Tianqi looked at Lu Tianshuang with a mysterious expression, "Shuang'er, you come with me, and I'll show you something." Then he turned and walked to the tent.

Lu Tianshuang followed his brother into the big tent and found a large wooden box one meter square, "Brother, what is this?" Lu Tianshuang asked curiously.

Lu Tianqi didn't answer, he stepped forward directly, and with a slight force in his palm, the wooden box was shattered, "Kababa!" With a few crisp sounds, the wooden planks were scattered all over the ground, revealing an earthy yellow ball of light with a diameter of two feet in the middle, which emitted a rich earthy yellow light, and there were many small energy whirlwinds surging slowly inside.

"The Source of Earth!" Lu Tianshuang recognized the ball of light in front of him at a glance, "Brother, why did you bring our family heirloom over too?" ”

"The conditions offered by the emperor Lao'er this time are too tempting," Lu Tianqi said with a straight face, "so we also have to invest some money, right?" Besides, this is also what my father and his old man agreed. ”

"And how do you use this thing?" Lu Tianshuang asked again, "I've only seen it once before, but I don't know how powerful this thing is." ”

"The source of earth is the mother of defense," Lu Tianqi explained, "It couldn't be better for defense, and that's why I brought you here this time." ”

"What does it have to do with me?" Lu Tianshuang was even more confused by what he said.

"The source of the earth needs to be stimulated with spiritual power in order to be effective," Lu Tianqi walked to the door of the big tent, opened the curtain and looked outside the camp, "Sister, you quickly input the spiritual power in your body into the source of the earth, so that a defensive barrier will appear above our camp, and you can't break through this layer of defense without strength above the god level." ”

Lu Tianshuang stretched out his hands, emitting a faint yellow spiritual power, without the support of the Explosion Yuan Pill, she only had the strength of a beginner archmage, after the source of the earth absorbed the spiritual power, it immediately shone with a dazzling earthy yellow light, "Huh! A burst of air sounded, and the light instantly smashed the entire tent into pieces, until it covered the entire camp before it stopped, and then, this energy gradually condensed into a transparent earthy yellow light shield on the periphery, tightly wrapping the entire camp inside.

"Bang bang bang!" The army of the undead roared, and the powerful impact made them turn into broken bones after hitting the earth barrier, and beyond the barrier, the broken white bones gradually piled up into a small mountain, and in just a moment, all the undead creatures were shattered.

"Good!" There was a burst of chanting from the Lu family camp, and a look of joy appeared on the faces of the two Lu Tianqi brothers and sisters.

"Beautiful hostess," Xiao Hei's voice sounded in Mu Yun's mind again, "Your army of the undead has been wiped out by the defensive enchantment they created with the Source of Earth!" ”

"The Source of Earth?" When Mu Yun heard this word, his eyes suddenly lit up, "Good thing!" Blackie, are you inside the enchantment now? ”

"Yes, I'm near their tent," replied the little black, "hehe, my beautiful hostess, do you want the little black gang to steal their earth source?" ”

"Black, you're so smart!" Mu Yun said with a smile, "However, now the time has not come, even if you steal the source of the earth, you won't be able to take it out, not to mention that they will definitely send heavy troops to guard it, and they won't give you a chance to attack." ”

"Well, then master, you just have to think of a way," Xiao Hei carefully inspected the surrounding guards, and then replied: "Master Yingming, this time they have called more than fifty guards to guard the source of the earth, and there is also a high-level summoning saint master in the heavenly domain, I can feel the powerful spiritual power emanating from his body here." ”

"Then you be careful to hide!" Mu Yun said worriedly, "The spiritual attack of a high-level summoning saint master is not a joke, once you are discovered by him, you have no chance to escape at all. ”

"Hehe, master, you can rest assured!" Xiao Hei said confidently, "Even if he finds out, isn't there still you who can save me, hehe, master, just remember to help me take care of Sister Bingbing." ”

"Little Broken Dragon!" Mu Yun scolded with a smile, "Be careful yourself!" Call me if you're in danger! ”

"Zhilu Dao!" Xiao Hei is well-behaved.

"Who is there?!" At this time, a deep voice came from the direction of the big tent, and the person who spoke was the high-level summoning saint master, and as soon as he finished speaking, a white light shot from his palm and hit Xiao Hei's chest.

"Ahh Xiao Hei was hit at that time, his whole body convulsed, and his body couldn't move, "Damn, I can be found by him when I become so small, he is really amazing!" Xiao Hei said secretly in his heart.

"You guys, go and have a look in the grass!" The summoning saint master pointed to the place where Xiao Hei was with his hand, and ordered a few guards beside him, "Look carefully for me, and don't let go of any place."

"Yes!" The guards ran over.

"Master, I was hit!" Xiao Hei used all his strength to transmit the voice to Mu Yun, "Come and save me!" ”
