Four hours later, Meng Chen finally carved out a passage on the other side of the Chiyan Mountain platform that reached the middle of the mountain.

The total length of the passage is nearly 350 meters, and a total of 4,320 gold coins were consumed, and 864 units of green quality stone were obtained.

When the fiery red rock layer was pierced, a blood-colored jade wall appeared in front of Meng Chen's eyes.

Meng Chen stretched out his right hand and pressed it on the surface of the blood-colored jade wall.

Airplanes~!

With a faint buzzing sound, golden runes appeared on the surface of the jade wall.

A force of countershock suddenly appeared, bouncing Meng Chen's right hand directly away.

"There is also a ban on the back of the dungeon?" Meng Chen was surprised.

Slightly different from the forbidden light shield at the front entrance, the prohibition here is fused with the blood-colored jade wall, and as long as the jade wall is touched slightly, the power of the shock will appear.

Meng Chen summoned Chris and Alfred and asked them to attempt an attack on the prohibition of the Scarlet Jade Wall.

It's a pity that neither Chris's punishment technique nor Alfre's wind elemental light blade can cause the slightest damage to the jade wall, and the two heroes are instead shocked by the jade wall ban.

As for Meng Chen's lord collection technique, if he couldn't directly contact it and continue to rub it, there was also no way to take this blood-colored jade wall.

"Damn! Could it be that spending 4 hours, losing 4,320 gold coins, and piercing through 300 meters of rock formations are just useless work? Meng Chen scolded in his heart.

After pondering for a moment, Meng Chen, who didn't want to give up easily, stretched out his right hand again and approached the blood-colored jade wall.

Arcane Dissociation!

Airplanes~!

As the white light continued to flicker, a buzzing sound sounded again, and the golden runes on the surface of the jade wall began to flicker continuously.

"Arcane dissociation seems to have an effect, and it doesn't get banned from retaliating. However, the continuous use of arcane dissociation will cause too much damage to mana! ”

At this time, Meng Chen's magic power was capped at 150 points, and if he used his full strength to perform arcane dissociation, he would need to consume 1 point of mana per second.

Two minutes later, Meng Chen's mana was exhausted, but the golden runes on the surface of the jade wall only became slightly dim.

Call~!

Meng Chen exhaled a long breath and took out a crystal bottle from his arms, which was filled with azure liquid.

These azure liquids are the pure magic of the Well of Eternity.

Once the Pure Mana leaves the Well of Eternity, the purity of the Mana decreases rapidly.

Originally, a drop of pure mana could replenish 10 mana, but after a day, it could only replenish 3 mana.

Before entering the Hellfire Palace, in order to prevent the lack of magic power, Meng Chen reluctantly carried five bottles, a total of five hundred drops of pure magic power.

Meng Chen poured a mouthful of azure liquid, and the dried magic power in his body was instantly replenished.

Afterwards, Meng Chen continued to cast arcane dissociation on the blood-colored jade wall.

。。。。。。

Just as Meng Chen was confronting the prohibition of the blood-colored jade wall, six mysterious people wearing cloaks appeared around Chiyan Mountain.

Six mysterious people were scattered in the six corners of Chiyan Mountain, each holding a hideous blood-colored spear, and slammed into the fiery red rock formation.

Then, six mysterious people pinched the seal in their hands, and they all silently recited some kind of mysterious incantation.

Thundered~! Thundered~!

With a dull roar, the six spears emitted a dazzling blood-colored light, and an invisible wave quickly spread around.

In the blink of an eye, this invisible fluctuation had enveloped the entire Chiyan Mountain.

Under the influence of invisible fluctuations, Chiyan Mountain began to shake slightly.

。。。。。。

"Huh? How could there be an earthquake in the Hellfire Palace? ”

At this time, Meng Chen, who was performing arcane dissociation, felt that the entire earth began to shake.

Airplanes~! Airplanes~!

The blood-colored jade wall let out a buzzing sound, and the golden runes in the jade wall began to dim rapidly.

Less than five minutes had passed, and when the earth was no longer shaking, the golden runes in the blood-colored jade wall had strangely disappeared.

With a face full of disbelief, Meng Chen reached out and touched the jade wall, and said in horror: "How is it possible? Could it be that these prohibitions are all tofu scum projects, and a single earthquake can break the bans? ”

Now that the ban has been broken, Meng Chen didn't think much about it, and immediately stretched out his hand and rubbed it.

When Meng Chen's palm rubbed back and forth ten times, a pit appeared on the jade wall silently.

"Gold -12, Stone (Blue) +4!"

The blood-colored jade wall is recognized as a building and can be recycled by rubbing it only ten times.

A few minutes later, Meng Chen finally pierced through the blood-colored jade wall.

Behind the blood-colored jade wall was a vertical passage, about twenty meters in diameter, and the bottom was pitch black and bottomless.

Meng Chen ordered the Rank 5 soldiers to be stationed outside the jade wall, while he himself led the two heroes into the vertical passage.

Arcane Force Field!

Since Chris was not yet able to fly, he could only fall down the vertical passage under the control of Meng Chen's force field.

Five minutes later, Meng Chen and the three of them had descended for at least a thousand meters, and finally left the deep vertical passage and entered a huge circular underground space.

This underground space was completely enveloped by a blood-colored jade wall, with a diameter of more than five hundred meters and a height of about one hundred meters.

In the center of the subterranean space is a circular altar with a large number of mystical sigils engraved on the surface of the altar.

These mysterious sigils still shimmer with golden light, and do not appear to have been affected by previous earthquakes.

In the center of the mysterious altar, there is a golden shining square ruler, surrounded by four large ancient seals - "Four Spirit Sealing Array".

"Treasure dungeon? It doesn't look like a place to hide treasures!"

Looking at the strange scene in the underground space, Meng Chen faintly felt a bad feeling in his heart.

The circular altar is surrounded by a circle of large metal cages.

There are a total of twelve metal cages, four of which hold large monsters.

A cow with a shoulder height of more than 15 meters, a body length of about 50 meters, and a body covered with topaz-colored thick armor.

A Xuanshui Jiaolong with a body length of nearly ninety meters, a waist of six meters thick, and a one-horned dragon.

A wind tiger with a height of more than 12 meters, a body length of nearly 40 meters, and a blue and white fur.

A flame bird with a body length of nearly twenty meters, a wingspan of more than fifty meters, and a body covered with fiery red feathers.

It may be that because they have been imprisoned for too long, these four terrifying demon beasts have already died.

Meng Chen didn't dare to touch the things on the ring altar, as for these four demon beasts...... A "wicked" smile appeared at the corner of Meng Chen's mouth.

Meng Chen came to the metal cage where Jiaolong was being held.

These metal cages are tailor-made for monsters, and humans can easily enter the cages through the gaps.

Reaching into the metal cage, Meng Chen didn't feel any restraint, and immediately shouted, "Alfred, quickly dig out the demon pills of these four demon beasts!"

"Yes! Your Lord!" Alfred bowed in response.

Then, Alfred turned into a phantom and appeared on the back of the dragon's neck in an instant.

Wind Elemental Blade! Wind Thrust!

Alfred, who was in full swing, shot out a light blade with the thin sword in his hand, stabbing towards the dragon's seven-inch part.
