After rushing along the road pointed out by Liu Boyong for a while, the strength level of the demons and ghosts who intercepted Zhou Yang was obviously improved, so that occasionally demons rushed past Zhou Yang and rushed at Liu Boyong and Yan'an behind him.

Zhou Yang was not surprised but happy to find this situation. He knew that he was going the right way.

He didn't care what impact those escaped fish would have on the two people behind him, but pushed forward vigorously and again.

Hiss, hiss, hiss!

Countless black smoke rose, but a magic array was triggered by Zhou Yang, causing countless highly toxic corpse water to pour down from the top of the cave, and then burned into black smoke by the "Qianyang real fire" burning on him.

Zhou Yang also experienced many attacks from the traps of the magic array. The power of the magic array itself can only be said to be ordinary. At most, it can make the friars in the golden elixir period pause a little.

However, the trap buried in the magic array may be seriously damaged even if the friar in the golden elixir period doesn't pay attention.

For example, the highly toxic corpse water poured down just now will corrode the body even if the friars in the golden elixir period are stained by it. The corpse poison in the body. If the magic instruments below the fifth level are stained by the corpse water, the legal prohibition in the magic instruments will be corroded and completely scrapped within half an hour.

This is only one of the more common traps. The most vicious trap Zhou Yang encountered is a ghost devil refined by the secret arts of the ghost road.

This kind of evil spirit head is that the devil friar selects a determined friar, and then tortures the other party in every way. When the other party's resentment is accumulated to the top, he will kill it and extract the spirit as the material for refining the evil spirit head.

The evil head Zhou Yang met was refined by the spirit of a friar of Zifu period. He hid in a magic array. Under a sudden sneak attack, he almost broke through his "Qianyang real fire" defense and rushed into his body.

Once thrown into the body by the evil head, even Zhou Yang's powerful spirit can't say it can resist its attack.

Fortunately, "the real fire of the sun is awesome enough". All kinds of magic that we encounter on this road can not cause any harm to Zhou Yang.

From this, we can also know why Guo Jinhong let one of his purple friars participate in the dangerous operation, and let him lead the way.

I don't know what means Liu Boyong has for accurate navigation. Under his guidance, Zhou Yang went all the way. Unexpectedly, he didn't go wrong once. When he rushed all the way in the underground Magic Cave Channel for nearly half an hour, his sight suddenly widened and entered a huge and incomparable underground cave Hall.

At a glance, he saw that the underground cave hall was at least 3000 feet long, nearly 2000 feet wide and up to 100 feet high. There were hundreds of black sarcophagus in the cave hall.

In the center of these black sarcophagus is a circular altar with a height of more than ten feet. On the altar is a dark gold coffin with a length of three feet and a width of half a foot.

The dark golden coffin looks neither like some kind of stone nor metal. It is also different from wood. It can be said that it is neither gold nor stone nor wood.

Generally, this kind of thing that looks neither gold nor stone nor wood is definitely a rare thing in the immortal world.

Sure enough, while Zhou Yang was still thinking about what material the dark golden coffin was made of, Liu Boyong, who followed him to the cave hall, lost his voice and shouted out the origin of the dark golden coffin.

"Dark iron wood! Is that the legendary dark iron wood? Has anyone ever been to the nether world? "

Nether iron wood!

Zhou Yang's attention was instantly attracted by the name of this strange spirit.

Many things in the world have the word "Youming" in their names, but Zhou Yang knows that most of the spirit objects with the word "Youming" in their names are original things in this world, not those in the legendary Youming world.

But he looked at Liu Boyong's shocked expression and listened to his words. Obviously, the so-called "dark iron wood" may really come from the legendary dark world!

"Elder martial brother Liu, do you know the origin of the coffin?"

When Zhou Yang was curious to ask Liu Boyong for details, Yan an couldn't help asking about it first. Obviously, he didn't know what the "dark iron wood" was.

"If the legend is true, the material used to forge the coffin should be the sixth level Yin spirit [netherworld iron wood] that only grows in the netherworld!"

"I only saw the record of this [dark iron wood] in an elder monk's travel notes. It is said that this thing only grows in the place with strong corpse Qi in the dark world. It can grow one foot every thousand years. Its texture is as hard as six levels of spiritual gold. It is the most precious refining tool regarded as a sacred thing by the demon monks!"

Liu Boyong said about the origin of "Youming iron wood" and looked at the dark golden coffin with bright eyes. His eyes were full of greed.

That's a sixth order spirit!

Although only the demon friars can make the best use of the sixth level spirit object with Yin attribute, it does not affect its value.

What Liu Boyong didn't say is that the coffin made of "Youming iron wood" has a special effect of "prolonging life".

If an immortal seals himself in a coffin made of "dark iron and wood" before the arrival of the birthday, he can temporarily seal the passage of his birthday and will not sit down because of the arrival of the birthday.

Liu Boyong is more than 900 years old, not far from the golden elixir monk's life of yuan.

Originally, he had lived for so many years. When there was no hope of promoting Yuanying, he had already made psychological preparations for the arrival of Shouyuan's deadline.

But he only had one thing to worry about, that is, he was worried that the "Tiandao gate" established by himself would fall down and break the inheritance because there were no golden elixir monks sitting in the sect.

The original arrangement he made was to work for Guo Jinhong in exchange for a certain degree of protection from the other party.

But now after seeing the coffin made of "Youming iron wood", another idea moved in his heart.

If he can win the coffin, he can seal himself in the coffin, hide the coffin in the door, and then pretend to be dead to announce that he has been seated more than ten or twenty years before the birthday of Shouyuan.

In this way, if someone wants to attack tiandaomen for this reason, he can kill the enemy at the critical moment, take the enemy by surprise and destroy these enemies who are trying to subvert their inheritance of tiandaomen.

"According to elder martial brother Liu, since this [dark iron wood] is so precious and rare, the immortal Heisha should not be buried in that coffin?"

When Liu Boyong was thinking about how to put the dark golden coffin into his bag, Yan an's words made his face change and stunned in an instant.

Yeah!

He knows that the "dark iron wood" coffin has the effect of sealing the passage of Shouyuan. Would the "Heisha immortal" who refined the coffin not know?

In this way, if Yan'an's words are true, the coffin is buried with the yuan Yingji evil cultivation of "immortal Heisha". Whether the other party has really sat down and fallen, or unknown!

"Elder martial brother Liu, why is your face so ugly? Did you find something? "

Zhou Yang has been paying attention to Liu Boyong's look. Seeing the sudden change in the other party's face, he immediately realized something and quickly made a sound to inquire.

"Nothing. I just heard what younger martial brother Yan said. I think of the life of immortal Heisha again. If the other party's remains were in the coffin as younger martial brother Yan said, I'm afraid we wouldn't easily complete the task assigned by the master!"

Liu Boyong's face changed, but he didn't truthfully explain the truth, but used an implicit word to prompt the danger.

"Elder martial brother Liu means that he is worried about the corpse of immortal Heisha?"

Yan'an frowned and was sure enough biased by Liu Boyong's words and thought of other places.

The so-called "corpse change" is that some high-level friars do not want to destroy the treasures they have accumulated in their life, and do not want people to easily get these treasures, so they move some hands and feet on their corpses before they sit down.

In this way, when someone enters their sitting place and collects the treasures left by them, their bodies will suddenly explode and attack the treasure taking friars.

It's normal for the "black evil immortal" to leave this means before his death.

However, Zhou Yang always felt that Liu Boyong's words were somewhat untrue. He felt that the other party was hiding something.

After all, the "corpse change" is not difficult to guess. In fact, when he saw the dark golden coffin, he also had this guess in his heart.

Therefore, he felt that if it was just a simple guess of "corpse change", Liu Boyong, an eight layer monk of the golden elixir, should not be so tarnished.

But these are his feelings and conjectures, which can not be publicized in his mouth. At present, he can only secretly raise his vigilance and say nothing more.

At this time, the most regretful thing in his heart was that he didn't bring the old ghost Xu Song. Otherwise, with each other's knowledge and attainments in magic, he should be able to give him many safety suggestions in this environment.

"In the opinion of elder martial brother Liu, what should we do next?"

Yan an frowned and looked at the quiet hundreds of sarcophagus in the underground cave hall. With a worried look on his face, he looked at Liu Boyong and asked what to do next.

It's strange to say that after they entered the underground cave hall, no demon corpses and ghosts came to attack them. It seems that this is a forbidden area for those demon corpses and ghosts outside.

"We..."

When Liu Boyong heard Yan'an's inquiry, he just wanted to open his mouth and say his plan, but before he finished, he looked motionless, suddenly shut up and looked in a direction deep in the cave hall.

Huh?

Zhou Yang and Yan an were stunned when they saw this, and then they couldn't help looking down his eyes.

At the edge of another cave hall more than 1500 feet away from them, three Jindan friars in scarlet robes suddenly came in through a passage behind them.

"It's the red eyebrow old monster of Lihuo sect. They're coming too!"

Yan an uttered a low cry, telling the origin of the three new golden elixir monks.
