Fierce battles continue.

To deal with this kind of monster with particularly strong defensive power, the ordinary spirit weapon flying sword can't even scratch its skin, Chu Tiancheng didn't have a good way for a while, so he could only keep driving the Xuanwu Hanxi Mirror to freeze it, so as to continue to consume its vitality and slowly grind it to death.

The saber-toothed demon flame turtle had already opened its mind, and soon understood the intentions of this hateful human, and roared angrily to lock on his figure and constantly launched a powerful counterattack, and for a while, the field flew sand and rocks, and the sky was dark, and the deafening explosion was endless.

The temperature of the surrounding environment also changed rapidly, and for a while the flames soared into the sky, thick smoke billowed from the sky, and dark red magma flowed everywhere, as if you were on top of a volcanic crater; After a while, the earth was frozen, snowflakes were flying, and the frost blue was cold enough to freeze the rocks.

In this extreme change of hot and cold, large swaths of hard underground rocks could not bear it and broke into powder.

"Damn, this guy is too tough?"

Chu Tiancheng secretly complained in his heart, took out a few pills that replenished mana and stuffed them into his mouth, his face, which was as white as paper, had a little more blood, and he gritted his teeth and continued to urge the Xuanwu Hanxi Mirror.

The lethality of this treasure weapon is indeed considerable, but with his current cultivation, it is still a little reluctant to use, not to mention the extreme consumption of mana, and the power exerted is not even half, otherwise it will not be entangled with that monster until now.

Especially the power of the opponent's counterattack was amazing, all the defensive spirit weapons on him and several junior sisters had been destroyed, and only the treasure-level Tan Yuan Rou Water Bead was left unharmed, but at the same time, he made two treasure weapons, which was no longer something that he could maintain for a long time as a monk in the Spirit Realm.

Chu Tiancheng can only pray now that he can take the first step to kill this big guy before he runs out of oil and the lamp runs out, otherwise he and several beautiful junior sisters will not want to leave this place alive. Don't forget that there are a lot of powerful monsters in the distance.

The saber-toothed demon flame turtle on the ground was constantly frozen in the terrifying cold air, and the thick ice quickly solidified on its massive body, forming a huge lump of ice, and then it roared and broke free. Fragments of cracked ice crystals flew everywhere, dark red flames billowed up all around them, and the terrifying heat vaporized all the ice cubes.

However, the damage of such an extremely cold attack to it was obvious, and after many rounds of tug-of-war, many subtle cracks had appeared on its thick tortoise shell, and its defense was obviously affected, and the flames floating around it were also much dimmed, which was a sign of a huge consumption of mana.

If it drags on, maybe you won't be able to support yourself until those few hateful humans are killed.

After a brief trade-off, the Saber-Toothed Demon Flame Turtle finally made up its mind. Taking a deep breath, his narrow eyes lit up abruptly, and the fire around him was magnificent, and the palpitating coercion permeated the space.

A faint fiery red golden glow flashed in its mouth, and then it expanded rapidly, and its brightness increased dramatically, until in the end, it was like a fiery red star, and a terrifying aura was brewing in it.

"Not good...... This big guy is going to fight hard?! ”

Chu Tiancheng's vision was certainly not bad, and he immediately came to the correct judgment, hesitated for a moment, and then continued to insist on attacking, and the four female disciples next to him also kept stimulating the Thunder Fire Talisman and Frost Talisman, and the thunder and ice edges kept falling, but this had no substantial impact on its rough skin and thick flesh at all.

The safest way at this moment is to run away at high speed, temporarily avoid this big guy who wants to go crazy and desperate, and then come back and kill it when he has recovered his strength.

However, in this unfamiliar underground world surrounded by many monsters, as long as Chu Tiancheng leaves, it is difficult to say who this seriously injured big guy will be cheaper. If he didn't get it, he fought to the death, paid a big price, and in the end, he made a wedding dress for someone else.

If you just stay, will you be able to block this extraordinary attack?

"Senior brother, what should I do?"

The four female disciples beside him asked nervously, they also felt that the situation was not good, and one of them did not respond properly, maybe it was really possible to capsize in the gutter.

"Don't worry, it'll be fine."

Chu Tiancheng seemed to have made up his mind, took out a crimson elixir from the storage bracelet, and swallowed it quite painfully, and suddenly his aura continued to rise, and soon reached the peak of the Yunling Realm, and then made a further breakthrough, reaching the Rongyuan Realm.

As his strength temporarily increased significantly, the protective light curtain around him became significantly thicker, obviously fully exerting the power of the treasure weapon.

Then Chu Tiancheng continued to take out a dark small bell to excite it, turning it into a black light curtain to protect the five of them, and it was actually another treasure.

Qin Luyan, who was hiding in the shadows and watching the battle, sighed secretly in her heart, she was worthy of being the seed that Thousand Illusion Peak focused on cultivating, and there were too many good things on her body, so she actually took out three powerful treasures at once.

The kind of pill that temporarily improves the cultivation of the realm is not particularly rare in the Demon Dao Sect, but the side effects are extremely great, and the user will be damaged in the meridians and internal organs, and it will take a long time of careful recuperation to recover; If it is serious, it will damage the Doji, and you will never be able to advance an inch again. Therefore, the slightest promising disciple will not consider it, and usually this thing is prepared for cannon fodder dead soldiers.

Of course, what Chu Tiancheng used was definitely not this kind of inferior goods, but the high-grade elixir carefully refined by the elders of the sect after collecting a variety of rare elixirs, and there would be no hidden dangers after taking it. Therefore, it is extremely precious and rare, maybe ten Liangyi Transformation Pills can't be exchanged for one such elixir.

"This elixir has a limited amount of time, so we have to deal with it as soon as possible."

Chu Tiancheng thought in his heart, the Xuanwu Cold Mirror was magnificent, and a thick and incomparably thick pillar of ice blue light shot straight down, locking the huge head of the saber-toothed demon flame turtle, and the terrifying low temperature and cold air filled the air, instantly condensing into a huge iceberg, completely sealing this big guy in it.

The next moment, the iceberg collapsed, and the huge body of the saber-toothed demon flame turtle suddenly rushed out, and with a tilt of his head, the bright fiery red star shot out, and in the blink of an eye, it was in front of Chu Tiancheng, and an earth-shattering explosion occurred.

"Boom ......"

A deafening roar echoed, swirled, and stacked in the underworld, and the rolling waves shook the dome slightly in the depths.

A fiery cloud of fire with a diameter of 100 feet bloomed in place, and the mountain where the saber-toothed demon flame turtle roost trembled, finally unable to withstand the terrible impact, disintegrated from the inside out, until it completely shattered, causing a heavy rainstorm of rocks and dirt.

Some of the powerful monsters that had been watching the battle from the periphery all fled into the distance like a desperate person at this moment, never daring to turn back.

After the terrifying explosion ended, the mountain peak disappeared completely, and a huge crater with a diameter of more than 100 meters appeared in place, and countless stone fragments were scattered underground in a radius of dozens of miles.

The saber-toothed demon flame turtle was lying at the bottom of the pit, thanks to the strong defense of its own tortoise shell, it still had a breath left, but it was already in a near-death state.

At the edge of the huge pit, the embarrassed Chu Tiancheng was half-kneeling on the ground, his clothes were torn and covered in blood, and as for the four female disciples beside him, they were all lying unconscious on the ground, looking at the situation.

He struggled to his feet, staggered to the bottom of the pit, drew a treasure-grade sword and busied it on the saber-toothed Demon Flame Turtle's skull for a while, sliced open the skull with difficulty, searched it for a while, and finally found a fist-sized blood-red crystal. The texture is soft to the touch, with a faint, ambergris-like aroma.

"Finally found it."

Chu Tiancheng breathed a sigh of relief, and joy appeared on his tired face. With this rare treasure, this action is not a loss.

However, at this moment, an elegant, charming, crisp and feminine voice came: "This thing is destined for me, so let's bring it!" ”

A cold blade pierced the heart and then exited his chest.
