Crossing the underground river and crossing the cave, an eerie light appeared in front of me.

The black pagoda of the ancient building was covered with corpses, and the blue light in the corpses was bright and dark.

The black burial pits below are almost entirely skeletons.

"Oh my God!"

This is an underground miracle, an ancient and mysterious world, full of mysteries.

"Nine-story demon building!" Professor Chen suddenly trembled with excitement: "This is the funeral form of the kings of the ancient demon kingdom. Nine-story demon building! ”

Sa Dipeng said: "I have seen the information before, Qinghai Xuewei has unearthed the remains of a nine-story demon tower. ”

"Not bad!" Professor Chen said, "The ruins are indeed a nine-story demon tower, which was destroyed by the heroic King Gesar before it was buried. And the one in front of us is a complete one. This trip is really worth it, hurry, record it quickly! ”

Qin Yu suddenly said, "Don't use flashlights, turn off all lights." ”

Hu Bayi also saw that something was wrong: "I'm afraid we've broken into the old nest of the fire ladybug." Professor Chen, this place is very dangerous, the nine-story demon building is the place where the fire ladybugs inhabit, once we wake up, I'm afraid it will be difficult for us to get out, I suggest, return immediately! ”

"Can't go back!" Professor Chen immediately objected, "This is a major archaeological discovery, we must be careful not to wake up those insects, and be careful to excavate." ”

"Hey, foreign girl, let's go!" The fat man found Yang Xueli who was heading towards the demon tower.

"Leave me alone!" Yang Xueli said, "I have to go and find the notes, you take care of Professor Chen." ”

"One by one!" Hu Bayi found that he couldn't control it, "Qin Yu, you protect everyone, fatty, come down and help Miss Yang." ”

Qin Yu looked at this mysterious Demon Mausoleum and looked up at the dome, which was covered with layers of glaciers.

"The land of Xuanice, the land of Xuanyin, sacrifice with blood, what a place of yin and evil!"

The nine-story demon tower was full of anger, I don't know how many grievances were backlogged, and the flames on those fire ladybugs were by no means ordinary fire.

In Qin Yu's eyes, this is simply the best place to refine treasures. The nine-story demon building is the best magic weapon material, even if it is practiced, it is also a magic treasure, but Qin Yu doesn't care, he urgently needs a magic weapon right now.

"Bump!"

A flash of light sent a white light flash through the entire underworld.

"Who told you to turn on the flashing lights!"

Sa Dipeng looked dazed: "I remember that I closed it!" ”

Qin Yu shook his head secretly, and a strange blue light had already appeared above the demon tower.

"Why are you still stunned? Run! ”

Hu Bayi and Yang Xueli rushed back wildly, "Hurry up, go quickly!" ”

Qin Yu slowly pulled out his long sword, the sword light danced, swept left and right, and his strength was wrapped in a circle, and there were constantly fire ladybugs being cut in half.

"That's amazing!" The fat man couldn't help but admire.

Yang Xueli said, "I heard that there are swordsman masters who can splash the water of the sword dance, I don't believe it, but now I believe it!" ”

Hu Bayi nodded matter-of-factly: "It should be a quick swing of the sword, stirring the surrounding air currents to form a barrier." Qin Yu, can you do it? ”

Qin Yu said, "You go first, I have my own way to get out!" ”

The brigade had withdrawn, and only they were left behind. The fat man and Hu Bayi retreated steadily, and Qin Yu was constantly moving outward.

Everyone crossed the underground river, and they saw Qin Yu and Hu Bayi and others who were constantly waving their swords.

"Roar!"

At this moment, a terrifying big guy sprang out from under the water, and lifted Hu Bayi and Wang Kaixuan, who were crossing the river, ashore.

"This is the prehistoric overlord salamander, this thing should have been extinct a long time ago!" Professor Chen's voice was full of horror.

"Fire!" Hu Bayi was hit like this, and suddenly became angry, and the four assault rifles fired together, and soon forced the overlord salamander to dare not show his head.

"Miss Yang, you go first, everyone goes. Run, climb, run! Fatty, leave the firepower to suppress, Qin Yu come here! What Hu Bayi was really worried about was Qin Yu.

Qin Yu made a neat backflip and fell into the water.

"Roar!"

The Overlord Salamander will squander this good opportunity and immediately pop out its head and sneak attack.

"Da Da Da!"

Hu Bayi and the others opened fire again, suppressing the overlord salamander. Qin Yu didn't ink and quickly rushed ashore.

But a bigger insect cloud is coming.

"Let's go!" Qin Yu said, "I can only let go of my hands and feet when you leave, I have my own way to get out!" ”

Hu Bayi's face changed slightly: "You're not kidding!" ”

Qin Yu smiled, "Don't worry, as long as you get out, I can get away at any time." ”

"Don't ink, let's go, Brother Qin, we're waiting for you above, be careful!" The fat man pulled Hu Bayi and quickly retreated.

The insect cloud split into two waves, one wave rushed towards Qin Yu, and a small wave rushed towards Hu Bayi and the others.

When the two of them left their sight, Qin Yu flipped his palm and took out a blood-colored spirit rune.

"Heavenly corpse fire! Rise! ”

"Manifest! Fudo Myowang! ”

The Yin God came out of the sheath and manifested itself through fire, and a huge flame Buddha immediately appeared behind Qin Yu's body.

The Buddha's phantom hand grabbed it, and the mica stone, earth mother magnet, purple iron, and ten thousand years of ice all flew in.

As for these little insects, they were directly driven back by the brutal Tiandu corpse fire.

"Up!"

The nine-story demon tower was forcibly arrested by Qin Yu, and the corpse of Tiandu was burned into nine flame tornadoes, gushing out layer by layer, burning the corpses and coffins in the demon tower, making them completely integrate into the nine-story demon tower.

"Go!"

Many of the condensed refining materials all fell into the nine-story demon building, and the Wanzai Xuan Ice was the main body and re-smelted.

The flame Buddha sealed his hands, and a large array entered the nine-story demon tower, and within a moment, the nine-story demon tower turned into a palm-sized blue pagoda.

Qin Yu returned to his senses at this time, his body flickered, and several ups and downs came to the demon tower.

Now is the most important part, and you have to let your blood go.

Slice open your palms and let the blood soak the entire pagoda, turning into blood-colored runes.

"Thanks to the Great Blood Spirit Technique in the Three Thousand Great Avenues, otherwise it will be really troublesome!"

"Lian!"

The Blood Corpse Danzhu flew out dripping and fell to the top of the tower, becoming a blood-colored town tower orb.

"Medium-grade treasures, nine-story demon towers, nine-nine-eighty-one large arrays, nine-fold space! The Blood Refining Pagoda has not been in vain! ”

Qin Yu's face was a little pale, obviously because he had lost too much blood. "The fire ladybug is a sharp weapon, collect it!"

The art of controlling insects is still the world of mortal immortal cultivation, it is too long, although these guys are not as good as the gold devouring insects and the flying purple scorpions, but they are numerous.

Qin Yu stuffed them all into the first space of the nine-story demon building, and the flames on their bodies were rare, but they couldn't refine them for a while.

The earth trembles, the earth's crust moves frequently, and if you don't go, you can't get out. Qin Yu didn't dare to slack off, and cast the dragon flying tiger step of the Feather Immortal Gate, flying away with a step of dozens of meters.
