The further you go through the passage, the narrower the road becomes, and the terrain goes all the way down, and the dark passage is filled with the smell of yīn cold cháo, but fortunately, the air here is not too muddy, and Char guesses that there may be some unknown vents in this underground cavern.

Walking at the front of the group, walking side by side with Char, the witch doctor's staff providing light.

Through the light, he could see the surrounding environment clearly, and Char's guess in his heart became more and more.

First of all, the passage clearly has obvious traces of artificial excavation, the walls on both sides of this passage are very flat, although it is covered with dirt and dust and cobwebs and other impurities left over the years, but the whole passage is obviously a square space, the ground is flat, the walls and the top are regular, Char carefully examined along the way, and found that this passage was built by a large and large boulder of incredible size.

The stones were obviously polished by hand, with a square shape and a smooth surface, and Char had examined the gaps between the two stones, and they were all very complete and angular.

"Do you Zaku people know that there is an artificial underground cave here?" Char smiled and said, "Maybe this place was built by your ancestors of the Zaku people?"

For this speculation, the Zaku witch doctor quickly vetoed: "Impossible. ”

The witch doctor then explained: according to all the existing ancient books of the Zaku tribe, there is no record of any underground secret caves built by the ancient Zaku people.

And...... "Zaku, don't make holes, we, not dwarves." ”

The length of this passage exceeded everyone's estimates, and according to Char's calculations, the group walked for at least two hours, and from the terrain that led all the way down.

"We're probably at least a hundred meters underground. Char sighed.

"Master, it's not my crow's mouth, but I have a very bad premonition. Tatara followed Char's side closely and whispered, "I always feel that we will encounter some unexpected existence. ”

The magician looked around, his expression a little panicked.

Finally, the front of the passage came to an end, but after reaching the end, to everyone's surprise, the road ahead was actually blocked!

At the end of the passage, there was a dead end, and a square wall stood in front of it, a huge, hard stone, covered with dust.

"No way?" Char frowned, he looked at it, and the witch doctor glanced at Garin behind him, and after the two talked in a low voice, he looked at Char: "What should I do?"

Xia Ya opened his mouth, his brows were tightly twisted together, and he shook his head and said, "It's unreasonable, this is unreasonable, such a long passage, it can't be a wall at the end...... Logically, the passage was dug to let people through, and since it was for people to pass through, then the end could not be a wall, so ...... It should be a door in front of us, a stone door that has been closed. ”

The others agreed with Char's statement, but how to pass through the stone gate in front of him was a difficult problem in front of him.

"Well, maybe we can go back and go back to where we started and take a look in the other way. Tatara's proposal was immediately rejected by Char.

What he meant was that even if you went back to the place you came from and chose a different passage, there was no guarantee that the other passages would not be closed.

"Dig it up and try it. The witch doctor offered her opinion. The idea was obviously more appealing to Char's appetite.

"We don't know how thick this door is. Tatara looked at the stone gate in front of him and frowned: "In case it is two or three meters thick...... everyone stepped back. ”

Char took a breath, his eyes flickered, seeing this kind of look, Tadora, who was familiar with Char's xìng, immediately realized that this master was going to do it.

After the Zaku warriors had retreated a dozen paces, Char stood alone in front of the stone door, he put away the knife in his hand, and pulled out the fire fork.

"Are you really going to do it?" Dora sneered in her mind: "Since this place was dug out by hand, then...... If you do it, you might have unpredictable consequences! I mean, something bad might happen. ”

"If you're not going to help, just shut up. Char muttered under his breath.

He took a deep breath, a flash of red light flashing in his eyes.

The red sè light quickly appeared on his arms, and then it was poured into the fire fork bit by bit, and the dark fire fork soon shone with a faint red sè light.

Crimson Murderous Dragon Thorn!

Char opened his mouth and exhaled, let out a low cry, held the fire fork in both arms, and stabbed fiercely at the stone wall in front of him!

With a bang, the fire fork slammed into the stone gate in the red light, and then the sound of the stone bursting was heard, and the stone gate made a crisp sound, and the roaring sound echoed in the narrow passage, shaking people's ears with a faint feeling of pain, and in the violent roar, the dust shook up and suddenly drifted away...... The entire passage seemed to shake, and the crumbling stones overhead and on the walls shook off the ground.

Under the crimson murderous and powerful lethality, coupled with this huge movement, Char was confident that even if this stone gate in front of him was really one or two meters wide, it would definitely not be able to withstand the bombardment of his dragon thorns!

Everyone was coughing on the drifting dust, but when the roar subsided, Char waved his arm to try to disperse the dust in front of him, and when he looked at it, he was dumbfounded.

Everyone hugged up and stood behind Char, looking at the stone door in front of them...... Char's fire fork pierced into the stone gate, but to Char's disappointment, the fire fork, which had always been indestructible, only pierced less than one-third of the length, and only in the part where it was pierced, the most shards that fell were only the size of a palm, while the entire stone gate remained intact!

Although the powerful power of the "Dragon Thorn" caused the passage to vibrate, the stone door in front of it obviously has stronger defense!

This is really the first time this kind of thing has happened to Char! His crimson murderous aura plus dragon thorns, plus the sharp and unparalleled fire fork, these three things together have always been indestructible! Not to mention a stone, even the finest jīng steel armor can be broken with a single poke!

Char was stunned for a moment, and soon, the side effects after casting the dragon thorn were reflected, Char's strength was consumed too much, he took a few steps back, and his whole body began to twitch, the severe pain in his muscles made him start to twitch, and his feet were soft, and Dodora next to him immediately supported him.

"Hell ......," Char sighed weakly.

Glancing at Char suspiciously, the witch doctor saw Char's pain, a trace of doubt flashed in her eyes, and then she stretched out her hand in front of Char, and her palm was a piece of black sè ointment: "Eat it, replenish your strength, and relieve the pain." ”

Char did not hesitate, nodded, Tatara took the thing and stuffed it into Char's mouth, and suddenly a bitter taste slid down his throat, as if the ointment would melt as soon as it was stained with saliva, and in addition to the bitterness, the cool feeling instantly spread in his chest, and suddenly made Char, who was burdened with pain all over his body, feel relaxed.

Garin and the other Zaku warriors carefully examined the stone door, and after a while, Garin glanced back at Char and said something.

"He said, you are strong, beyond his, expected. You are, mighty warrior. ”

Garin's eyes were undisguised admiration, but Char was smiling bitterly.

Strong...... Of course, he himself knows the power of the dragon thorn, but this damn stone gate ......, "Master, this door is strange. After Toddoro helped Char to sit down, the magician pushed past the other Zaku warriors and walked to the door, and after carefully examining the small gap in the door that had been pierced by Char's fire fork, he turned around and said loudly, "It's not made of stone!"

Hearing Tadoro's voice, the witch doctor was the first to react, the witch doctor quickly rushed to the door, approached the gap and looked at it carefully, the witch doctor's voice was a little strange: "It's not a stone!"

Not a stone?

Char grinned, and he gasped for breath: "Wait a minute, I need to take a break...... Then I'll try again. ”

He still had an idea in his heart, this trick dragon thorn just now was not his limit, he also had the big crystal given by Cavishir, as long as the large crystal was embedded on the fire fork, then the power of the crimson murderous aura and the dragon thorn could be increased several times.

But the consequences were just as great: he had tried such attacks before, but each time he had to be knocked unconscious for at least a day.

Totaro sat down at the door with two people, each of them holding a fragment that had fallen off the stone door in their hands, the fragment was very small, the one that Totaro was holding was only the size of a finger, the magician quickly took out a bottle from his bosom, poured out some potion and sprinkled it on the stone, and then came closer to observe it carefully, and even put it into his mouth and licked it twice. He took out another magnifying lens and looked at it carefully.

After that, he just looked at it in his hand for a while, and finally the witch doctor let out an exclamation.

"What's wrong?" Char barely sat up straight.

"Sir, I have good news and bad news...... Which do you want to hear first?"

Todora had a strange look.

"Listen first. Char snorted.

"Master, we have made a fortune!" the magician seemed to be a little excited: "This is a kind of 'iron jīng'! It is a treasure that all blacksmiths dream of! And according to the current iron-making technology, only the best blacksmith master can refine the 'iron jīng'! And the cost is extremely expensive! Only three hundred catties of the finest iron can refine less than one pound of iron jīng! And the refining process is extremely complicated...... This kind of thing is a good thing that all samurai dream of! If iron jīng is used to forge weapons, as long as it is tempered on the blade, it can make an ordinary weapon instantly become an invincible divine weapon! According to the knowledge I have, this kind of thing is no less valuable than Mithril!!"

Char froze: "According to what you mean, the bad news is ......"

"The bad news is...... Unless you can maintain the strength of that blow and hit it a few hundred more times, then maybe we have half a chance of blasting it open!"

Hundreds of dragon stabs?!

Char opened his mouth weakly.

Are you kidding!

With the current strength of the turtle, let him use the dragon thorn, he can only use it once in his ordinary state, and if he uses it twice, he will have muscle spasms all over his body, and then his pores will burst, and his whole body will be bloody, and then he will not want to walk on the ground if he does not raise it in bed for a few days.

Hundreds of dragon spurs?

According to Dora, even a real dragon knight in ancient times would not be able to use such a trick as a dragon thorn hundreds of times!

Todora's words made Char immediately frustrated, but soon he walked over.

"It's special. She pointed to the texture of the door: "I've seen this kind of thing." The witch doctor's tone was very solemn, and then she spent a lot of words explaining to Char: in their Zaku tribe, there are several holy artifacts that have been preserved in the tribe for an unknown number of years, and the texture seems to be similar to the texture of this door, this kind of thing is not hard, hard to the point of unimaginable.

Char was depressed for a while, but soon he regained his courage.

"There must be a way!" The turtle scratched his hair hard, and there was a light in his eyes: "This is a door! Since it is a door, there must be a way to open it! Otherwise, there is no need for the people who built this place to set up this passage, just build a wall! Since it is a 'door', there is a way to open it!"

Having grasped Char's meaning, the witch doctor quickly summoned all the Zaku warriors to search carefully around the door, and the Zaku warriors swept away the dirt and dust from the walls, carefully examining every possible trace bit by bit.

Finally, after a long period of busyness, something was discovered.

A Zaku warrior shouted, called his companion over, and on the side of the door, knocked open the thick layer of dust that had congealed into lumps from the wall, revealing something suspicious as a large cloud of stone chips and dirt fell.

On the wall is an oval-shaped stone, which is deeply embedded in the wall, only showing a little bulge on the outside, because of this, after being covered by a thick layer of dust, no one originally noticed this place.

In this oval-shaped protrusion, there is also a circle of patterns carved on the wall around it, which is evenly distributed into a grid outline.

"It looks, it's like...... Some kind of scale?" Toddoro looked at for a moment, then at Char.
