The two men walked along the Flame River. This underground river was truly amazing. After walking for more than a hundred miles, they still couldn't see the end, and the river was getting wider and wider.

The underground river at this time can no longer be called a river. It should be said to be a big lake. The lake is dozens of miles wide, with magma rolling inside and bubbles constantly coming out. The heat is coming in waves like sea waves. If it were not for the protection of light energy, the hair would have been burnt long ago.

"It should be here." Li Xiu looked at the lava lake and saw a black pillar faintly standing in the center of the lake.

Li Xiu's mind moved, and the Fire Lotus Sword flew out, directly transforming into a fire lotus and flying into the air.

Li Xiu grabbed Ah Fei's arm and flew onto the Fire Lotus. The Fire Lotus Sword carried the two of them toward the black stone pillar in the center of the lake.

When they got closer, they found that the pillar was much larger than they had imagined. The exposed part alone was more than ten meters high, and it would probably take two people's hands to hug it.

"Is it this?" asked the bandit, looking at the black stone pillar.

"It should be correct." Li Xiu's eyes fell on the top of the stone pillar. On the flat top of the pillar, there was actually a black metal chain connected. The metal chain seemed to have grown out of the stone pillar, and there was no trace of connection.

According to the records, the Great Demon King Burning Sky is under this stone pillar, and the stone pillar must be pulled up to lure the Great Demon King Burning Sky out.

Li Xiu felt that the wording might not be used correctly. Rather than saying that the Great Demon King Fentian was hiding under the stone pillar, it would be better to say that he was sealed underneath.

If the stone pillar is not pulled up, the Great Demon King Burning Sky will have no way to get out.

According to the records, the material of this stone pillar is unknown and it is almost indestructible. It can only be pulled up by pulling the metal chain on it.

But the metal chain itself is an extremely dangerous object. Anyone who touches it will be locked up and unable to escape.

If the Great Demon King Burning Sky comes out at that time, we can only fight him with chains, which will be a great loss.

Li Xiu was not sure whether the forbidden light could break the metal chains, so he could only bring A Fei over.

It's useless to lock up the bandit with that metal chain, as he can just use the abandon skill to leave.

Ah Fei nodded, jumped off the fire lotus, and landed steadily on the top platform of the stone pillar.

"Pay attention to safety. If anything goes wrong, use the give up skill and leave immediately. Don't rely on luck." Li Xiu warned.

Ah Fei hummed, stretched out her hand and carefully touched the chain. Nothing unusual happened until she held the chain in her hand.

The bandit held the chain with both hands and tried to pull it, but the chain didn't move at all. It seemed that it was welded to the stone pillar.

After all, she was already at the Soul Casting level, and the force of this pull was so strong, but she could hardly move it at all. It was obvious that this thing could not be pulled by brute force.

The bandit did not hesitate and cut his finger, letting his blood drip onto the chain.

This is the method recorded in the information. Only by dripping blood on the chain, the chain will absorb the blood, and only the person who donated the blood can pull the chain.

Blood dripped onto the chain. The chain was clearly made of metal, but it seemed like a sponge and directly absorbed the bandit's blood without leaving any trace.

After sucking a lot of blood, the chain gradually began to glow red.

Suddenly, the chains moved on their own and wrapped around the bandit's wrists like shackles.

Li Xiu held the forbidden cannon tightly, ready to launch an attack at any time. If anything unexpected happened to the bandit, he would immediately blast out the forbidden light.

Fortunately, the chain was just as recorded, only locking the bandit's wrists, and there was nothing unusual.

The bandit gave Li Xiu a reassuring gesture, then looked down at his entangled wrist, reached out to grasp the chain that was glowing red, and pulled it hard.

The chain, which Ah Fei couldn't pull no matter how hard he tried, was actually pulled up a little bit with just a slight pull.

As the chain was pulled up, the huge stone pillar also slowly rose a little, and the rising distance was consistent with the length of the chain pulled out by the bandit.

The bandit no longer hesitated. He pulled the chain repeatedly with both hands, pulling it out piece by piece, and the black stone pillar rose higher and higher.

When the height of the stone pillar was about to reach the stone ceiling of the underground space, no matter how hard Ah Fei tried, the chain could not be pulled up.

I saw magma rolling in the magma lake below, the red light was getting brighter and more dazzling like the sun, and the temperature in the air was also rising rapidly.

In the boiling magma, a huge body emerged, and magma was flowing on the huge body like pig iron.

Li Xiu and A Fei both saw what the thing that rushed out of the lava lake was. Even though they had known it for a long time, they were still shocked.

The upper body of the demon that was exposed outside the lava lake was more than ten meters tall. Its entire body seemed to be made of black iron, with four arms and two faces. Its face was ferocious, like a god or demon enshrined on an altar, and it was extremely oppressive.

"A Fei, let's go." Seeing that A Fei had not used the give-up skill to leave, Li Xiu hurriedly reminded him loudly.

The first thing the Burning Sky Demon King would do when he comes out is to devour the person who pulls up the chain. With their bodies locked up, ordinary people wouldn't even have a chance to escape.

"Be careful." After saying this, the bandit activated the abandonment skill, and his body locked in chains disappeared.

Seeing Ah Fei disappear, Li Xiu finally breathed a sigh of relief. It turned out that giving up was a magical skill. Even a place like this could not trap Ah Fei.

As the bandit disappeared, the chain gradually slid back and the stone pillar began to sink slowly.

Li Xiu had no more scruples and fired the forbidden cannon at the Great Demon King Burning Sky, half of whose body emerged from the magma lake.

The orange-red beam of light instantly pierced through the void, causing circles of gas explosions, and instantly arrived in front of the Burning Sky Demon King.

The two faces of the Great Demon King Fentian are very strange. It is not that one face is in front and the other face is in the back, but both faces are in the front.

His face was divided into two in the middle, one on the left and one on the right, as if the two faces were compressed and squeezed together.

The four eyes are side by side, the two noses and the two mouths are also side by side, which is very symmetrical.

Seeing the forbidden light blasting towards him, both faces of the Burning Sky Demon King showed strange smiles. He raised his four arms, and his four palms formed a circular mark, which instantly turned into a circular halo like fire.

Li Xiu's forbidden light bombarded the aperture, and a horrifying scene occurred. After the orange-red light column came into contact with the flame aperture, it was like melted steel, dripping like iron juice, and it was unable to pass through the flame aperture.

"The Doomsday Furnace of the Great Demon Lord Burning Sky is indeed powerful. It can even melt the forbidden light." Li Xiu was not surprised and admired it secretly.

The information has clearly stated the function of the Light of Truth of the Great Demon King Burning Sky, which can melt all things and all lights, so it is not surprising that the forbidden light can be melted.

The forbidden light itself is not a particularly strong offensive divine light. Its main function is to break the forbidden power.

Its destructive power is more than enough to deal with ordinary gods, but when facing top gods like the Burning Sky Demon King, its destructive power is slightly weaker.

However, this is not a big problem. In the battle between gods, the strength of the light of truth does have a great impact, but it is not the only criterion for determining victory or defeat.

Seeing that this forbidden cannon did not work, Li Xiu activated the forbidden cannon again. The orange-red light in the forbidden cannon burst out in a spiral shape again, and a beam of light was fired out again.

Only this time the beam of light became more red, instead of the previous beam that was mainly orange.

This is the Forbidden Cannon that uses the seven forbidden skills. The Forbidden Cannon uses the seven forbidden skills to release beams. Unlike the infinite skills in the Gatling state, each taboo can only fire one shot. Normally, Li Xiu does not use the skill cannon.

A mixture of red and orange beams, like the bright red color of flowers, instantly bombarded the front of the Great Demon King Burning Sky again.

The entire body of the Great Demon King Burning Sky has stepped out of the magma lake, and the magma is flowing on his black iron body. Facing Li Xiu's bombardment, the four hands of the Great Demon King Burning Sky once again formed a furnace halo and trapped the oncoming light column.

However, this time the light beam was not completely melted by the furnace aperture, and a part of the bright red light beam dripping with red liquid passed through the aperture.

This forbidden light has the immortality of the seven taboos, making it immortal and almost indestructible.

The seven taboos used on the Light of Truth are different from usual times in that they no longer act on the enemy, but directly act on the Forbidden Light, giving the Forbidden Light skill characteristics.

Even so, the light of the Doomsday Furnace still melted some of the forbidden light, which shows how terrifying the light of the Doomsday Furnace is.

The forbidden light, which had been missing for several circles, was about to hit the chest of the Burning Sky Demon King, but the Burning Sky Demon King's body suddenly split into two, and the forbidden light blasted through the gap in between.

After the forbidden light completely passed through, the two halves of the Burning Sky Demon King's body merged into one again. The pair of arms above formed a strange hand seal, and suddenly a fire dragon gushed out from between the hands, roaring like a real dragon and swallowing Li Xiu.

Li Xiu did not retreat either. He fired another shot at the roaring fire dragon. This time it was an ordinary forbidden light without any additional skills.

The orange-red beam of light collided with the roaring fire dragon, instantly producing a terrifying light explosion. The shock wave lifted the magma below hundreds of meters, and it expanded and rolled outward rapidly like a giant golden-red donut.

This attack was so effective that the fire dragon and the forbidden light were shattered at the same time. However, the next second, the shattered fire dragon condensed into one again and swallowed Li Xiu.

"The top-level light of truth is indeed extraordinary." The fire dragon was already in front of him, but Li Xiu still did not retreat. He carried the forbidden cannon and fired another shot directly at the fire dragon's face.

In this shot, Li Xiu used the immortality among the seven taboos. Ordinary immortality bullets can repair the injured body.

However, the immortality acting on the forbidden light makes the forbidden light possess the characteristics of immortality.

The red light column collided with the fire dragon, and the fire dragon was shattered. The body of the red light column was also refined by the fire dragon's flames and continued to melt into liquid drops. However, the intensity of the forbidden light did not decrease, and the melted part recovered immediately.

Until the fire dragon was shattered, the forbidden light continued to blast towards the Burning Sky Demon King as if it was not damaged at all.

The two faces of the Great Demon King Fentian were twisted with strange smiles, and his lower hands formed seals at the same time. A tornado-like flame burst out of his hands and circled towards the forbidden light.

The forbidden light was trapped in the tornado and was affected by it, deviating from its original trajectory, flying past the Great Demon King Burning Sky and crashing into the magma lake together with the tornado, causing the entire magma lake to surge and gush out like a fountain. The entire underground space was like a magma rain, with magma gushing out everywhere, hitting the stone ceiling and then falling down.

Li Xiu and the Great Demon King Burning Sky fought back and forth continuously, but neither of them could gain the upper hand. The light of the Great Demon King Burning Sky's Apocalypse Furnace was in no way inferior to the forbidden light, and his skills and means were also endless.

The battle between the two gods turned the underground space and the lava lake upside down, but Li Xiu still didn't gain any advantage.

Li Xiu was not surprised but happy. The stronger the Great Demon King Burning Sky was, the higher its quality was, and the divine gemstone must be of the best quality. If he could be promoted to the divine position with its divine gemstone, the light of truth he obtained would be stronger.

But how to kill the Great Demon King Burning Sky is a troublesome matter.

Li Xiu has used five of the seven forbidden cannons, but is still unable to defeat the Great Demon King Burning Sky. The only two skills left are not to be used: not killing and not sacrificing.

The light of the furnace of the end of the world can melt all the lights of all things. The forbidden light can hardly suppress the light of truth, and the attributes of life and death are of no advantage at all.

"Then I have no choice but to use my spiritual sense." Li Xiu's eyes sparkled, and a white vertical eye appeared between his eyebrows.

The Great Demon King Fentian, who was staring at Li Xiu, suddenly had his four eyes wide open and his body did not move, as if he was stunned.

"Now." Li Xiu activated the forbidden cannon again, and the seven forbidden no sacrifices were also activated at the same time.

A bright red spiral beam of light spurted out and directly hit the head of the dazed Demon King Burning Sky.

The original ability of the No Sacrifice Bomb is to seal the opponent's special ability, but when it is used on the Forbidden Light, it enhances the power of the Forbidden Light. It is the strongest attack skill of the Forbidden Light.

The enhanced forbidden light bombarded the face of the Great Demon King Burning Sky, instantly producing a terrifying light explosion.

Under the light explosion that rose like a mushroom cloud, the huge body of the Burning Sky Demon King also fell into the magma.

Boom!

The body of the Great Demon King Burning Sky fell into the lava lake, stirring up lava waves hundreds of feet high.

"Is it killed?" Li Xiu looked at the rolling lava lake, but did not rush in to check whether the Burning Sky Demon King was killed.

Crash!

The lava lake suddenly rolled and surged, and the body of the Great Demon King Burning Sky rushed out of it again. The two strange faces now looked like two sunken broken iron pots, and the facial features could no longer be distinguished.

"It didn't even blow its head open?" Li Xiu was also a little surprised. Even with the forbidden light without the blessing of the sacrificial bomb, it couldn't blow open the head of the Burning Sky Demon King. Its body strength was really terrifying.

Although he is not as strong as Guan Jinghao in his fallen god state, he is still the strongest demon spirit Li Xiu has ever seen.

The Great Demon King Burning Sky seemed to be completely enraged, and golden-red light patterns like magma appeared on his black iron body.

The golden-red light patterns quickly spread over its body, and it looked as if its body was hollowed out by the light patterns. Its entire body was like a huge demon furnace. Under the high temperature, its entire body radiated astonishing heat. Everything close to it was melted, and even the magma around it was burned to ashes by the high temperature.

Magma-like liquid gushed out from the light pattern, filling its sunken face. The liquid twisted and deformed, and then quickly solidified, restoring the two faces of the Burning Sky Demon King to their original state.

The furious Burning Sky Demon King stared at Li Xiu with his four eyes as hot as magma. He clasped his four hands together and emanated an endless amount of golden-red light.

The light radiated throughout the entire underground space. Anything that came into contact with the light was either turned into ashes or burned into liquid iron.

The stone roof and the sky melted under the illumination of that light, turning into magma that kept dripping down.

The flower armor on Li Xiu's body began to melt under the light, and the outer layer had turned into red juice. The body of the forbidden cannon also showed signs of melting.

At this moment, the Great Demon King Burning Sky really looked like a great demon who wanted to burn the world to ashes, and he was incredibly powerful.

"The light of the Doomsday Furnace is so strong." Li Xiu admired it more and more, but his hands were not idle.

He had long known that the Great Demon King Burning Sky had this trick, and he fired the forbidden cannon again, but this time he was not going to use the forbidden light to bombard the Great Demon King Burning Sky.

The light patterns on the forbidden cannon lit up in circles, but unlike before, this time they spread from the muzzle inside.

The Forbidden Cannon seemed to have turned into a giant vacuum cleaner, sucking in all the light from the nearby Doomsday Furnace.

As a large amount of light from the Doomsday Furnace was absorbed, the barrel of the Forbidden Cannon became brighter and brighter. Soon, the entire barrel seemed like a red-hot iron block, shining brightly all over.

"It's so horrible!" Li Xiu discovered that the body of the Forbidden Cannon had actually begun to melt. Even though he used the Super Bottle Absorption to absorb the Light of the Apocalypse Furnace for his own use instead of confronting it head-on, it was still difficult to contain a large amount of Light of the Apocalypse Furnace, and the body of the cannon began to melt from the inside.

"Let's do it again." Li Xiu's white vertical eyes opened again, causing the Burning Sky Demon King to fall into illusion again, his body unable to help but become dazed.

"The Seven Taboos: Don't Kill!" Taking advantage of the moment when the Great Demon King Fentian was in a daze, the Forbidden Cannon burst out with unparalleled light.

A giant beam of light that blended gold, red and orange spurted out, and the color was as gorgeous as a lotus.

The Great Demon King Burning Sky had no chance to dodge and was hit directly on the chest by the beam of light. Light exploded, flames bloomed, and the Great Demon King Burning Sky's entire body was submerged in the gorgeous color of the beam of light.
