Chapter 349: Dao Treasure Treasury!

Swaggeringly set up a formation around those monsters. This formation is called the True Fire Formation. Seventy-two fire-gathering talismans are used to form the formation. At that time, only the Suhang Samadhi True Fire is needed to turn the formation into a sea of ​​flames. These monsters There is no escape.

Because no monster stepped forward to obstruct it, the formation was quickly set up, and Su Hang withdrew from the formation, waiting quietly for the effect of the military ban to disappear.

Soon, there was a turmoil in the space, and an invisible ripple recovered like a tide, and the light of the military ban hanging in midair converged, and quickly flew back to Su Hang's hand.

When the time was up, Su Hang felt that at that moment, his skills and mana had returned to him, and he immediately put the military prohibition order into the storage ring.

It's now.

Sacrifice the real fire of samadhi with all his strength, a fireball sprang out from the palm of his hand, and threw it directly into the real fire formation. The formation seemed to be filled with gasoline, and the flames shot up into the sky instantly, drowning those monsters who were still inexplicable.

"Ho, ho, ho..."

Painful and angry roars came from the sea of ​​fire, and Su Hang quickly retreated to avoid being injured by the fire.

A tiger monster and a basilisk rushed out of the sea of ​​flames, bathed in flames, screaming in pain, and rushed towards Su Hang. However, before rushing far, they could no longer bear the burning of the flames and fell on the ground. The ground turned up.

Samadhi real fire, that is not ordinary fire, it is not only harmful to ghosts, but also very harmful to ordinary creatures.

"Ahem..."

The monster was submerged in the sea of ​​flames, but the thick smoke choked Su Hang so badly that he quickly hid far away. He secretly miscalculated in his heart. The flame needs to consume oxygen. This underground palace is a closed space. How much oxygen can there be? With such a big fire, wouldn't the oxygen be exhausted soon?

The key is that the smoke is still choking.

Fortunately, Su Hang has already entered the state of fetal breathing, so he can go without breathing for a long time. He only needs to wait for the fire to pass through the ninth floor, and he must be able to get out.

After about 20 minutes, the roar in the sea of ​​fire gradually disappeared, and the flames in the real fire array were also quickly extinguished, leaving a piece of scorched earth that had been scorched.

Those monsters were also burnt to the point of leaving corpses, turned into bits of starlight, and were recovered by the runes on the top of the underground palace.

The underground palace was full of burning smells, the smoke and dust in the air could not dissipate for a long time, and Su Hang did not dare to breathe, trying to calm his body as much as possible to reduce oxygen consumption.

Ninth floor, is this a pass?

Su Hang was full of anticipation in his heart. This underground palace has nine floors in total, and now the nine floors have passed. If Zhang Daoling hid any treasure in this underground palace back then, then that treasure should be his own.

In Su Hang's anticipation, a ray of yellow light came down from the ceiling of the cave, and something landed in front of Su Hang.

Su Hang immediately bent down and picked it up.

It was a small box, about the size of a children's schoolbag, with a square bottom and a semicircular lid, carved with many exquisite golden patterns. Anyone who saw it would be a treasure box.

There was a lock hanging on the box. Su Hang searched for it but found no key. He tore it hard, but failed to tear it open. The material of this box is definitely not ordinary, and the things inside are probably not simple.

Just give a box, but not a key, what's the point?

Is it possible that I have to find the key again?

What urine?

This is already the ninth floor, where else can I find the key? Is it possible to try again?

It’s obviously impossible to re-enter, and Su Hang doesn’t have that kind of thought, let alone that ability. The battle just now was already dangerous and dangerous. It can be said to be a coincidence victory. If we do it again, whether we can win or not is not certain. .

He took out the Zichen sword and slashed through it.

To open a treasure chest, you don't need a key. Sometimes, it's better to be simple and rough. When the sword flashed across, there was only a clang, and the golden lock hanging on the treasure chest was directly cut off by Qi Gen.

The corner of Su Hang's mouth traced a slight arc, so what if there is no key, it was opened by me.

What will be in the box?

Su Hang was a little excited, could this be Zhang Daoling's treasure hidden in the underground palace?

The tip of the sword was inserted into the gap between the lid and the body of the box, and with a slight flick, the lid was lifted off immediately.

In the imagination, it should be golden and blinding.

Su Hang was ready to cover his eyes, but when the lid was opened, Su Hang was quite surprised.

Inside the box, there was only a small tripod with four legs and four ears, half a foot high, pitch-black, with oracle bone inscriptions engraved on the body of the tripod. The lid sealed the mouth.

"Is this supposed to be a medicine cauldron?"

Su Hang lifted the lid of the cauldron, only to smell a strong smell of medicine, as if it had been brewed for a long time, and the smell was refreshing. There is no doubt that this is a medicine cauldron, and it is also a frequently used medicine cauldron.

Otherwise, the medicinal smell inside would never be so strong.

Pull out the system and scan it, sure enough, the guess is right, this small tripod is called Tianshi tripod, which has reached the level of middle-grade fairy treasure, it is the medicine tripod used by Zhang Daoling, the ancestor of Tianshi and Taoism, who made alchemy. It is said that Zhang Daoling lived on Longhu Mountain For refining dragon and tiger golden elixirs, the cauldron for refining alchemy is probably the one in front of you.

Zhang Daoling actually kept the Celestial Master Cauldron. It seems that at that time, Zhang Daoling, either the deadline was approaching to explain his funeral, or his strength was already so strong that he couldn't even look down on the level of this middle-grade fairy treasure.

Otherwise, who would like to lose all the treasures they have in their hands?

From Su Hang's point of view, the latter may be more likely. To build this underground palace, Zhang Daoling's strength is by no means easy, and he may have already surpassed the Jindan realm at that time.

Another celestial treasure, although he knew nothing about alchemy, but no matter what, this thing was already the highest-grade treasure that Su Hang had ever seen, and there would be opportunities to learn alchemy in the future.

Put away the Heavenly Master Cauldron, and put away the damaged box as well. The material of the box is special, maybe something else can be made out of it in the future.

The air in the underground palace was frighteningly dirty, and the smoke could not dissipate for a long time. Seeing that the teleportation array had been opened, Su Hang stood up without hesitation, no matter what, let's leave the underground palace first.

The water-blue halo enveloped Su Hang, and disappeared from the ninth floor in an instant.

——

"Huh? Where is this?"

When Su Hang opened his eyes, what he saw was not mountains and rivers, let alone that old face in a pot, but another cave.

However, this cave is much smaller than the ninth floor.

There is a high platform in the middle, and Su Hang is standing on the high platform at this time, stepping on the teleportation array under his feet.

"Damn it, won't you still fight?"

Su Hang instantly felt that the dog beeped, isn't it the nine-story underground palace? Why is there a tenth floor?

According to the urine nature of this underground palace, on the tenth floor, isn't there a group of monsters at the Golden Core level waiting?

This time he couldn't afford it anymore, Su Hang just wanted to withdraw quickly, not to mention a group of Gold Core monsters, even one or two Gold Core monsters were enough for him to choke on.

However, at this time, Su Hang discovered that there seemed to be no movement on this floor.

After waiting for a while, Su Hang didn't see any monsters coming out, so Su Hang was stunned for a moment. Could it be that there is no danger on this floor?

Only after passing through the ninth floor will he be teleported to this place?

With a bit of apprehension, Su Hang walked down the high platform, and sure enough, no monster came out again.

Looking around carefully, this space is very small, even smaller than the first floor, and it doesn't look like there are monsters.

It was the size of a basketball court, surrounded by tall bookshelves filled with bamboo slips.

Su Hang walked over to a bookshelf. For more than two thousand years, the bamboo slips on the bookshelf were a little old, but they were still strong and showed no signs of being corroded by the years.

Carefully remove the roll and unfold it gently.

"Just once!"

All of them are beautiful ancient characters, which are the scriptures of the "Zhengyi Jing" of Tianshidao, and all of them describe the practice and Taoism of Tianshidao.

There are not many words that can be recorded in a scroll of bamboo slips. Su Hang took a look at it. The entire bookshelf has more than ten floors up and down, and there are at least hundreds of volumes. It is a complete set of "Zheng Yi Jing"

"This scripture, I'm afraid that today's teacher's collection of books is not so complete, right?" Su Hang was delighted to see that there was such a place under the ninth floor of the underground palace.

Putting the bamboo slips back on the bookshelf, Su Hang went to the next bookshelf and took down a roll of bamboo slips from the bookshelf.

"I want to pay attention to you!"

Another volume of Taoism, which I would like to annotate. It is said that it was written by Zhang Daoling, the celestial master. gap.

Since this underground palace was left by Zhang Daoling, this volume of scriptures must also be the original, and its value is by no means comparable to the version circulated in Huaxia Xuanmen today.

Lao Tzu wanted to note that it also occupied the entire bookshelf, with hundreds of bamboo slips in total.

Looking to the side, "The Yellow Emperor's Jiuding Danjing"

"Huh?"

Su Hang's eyes lit up. Legend has it that Zhang Daoling first retreated to Beiman Mountain to practice Taoism, and later obtained the Yellow Emperor's Nine-Ding Danjing, and practiced it in Fanyang Mountain.

The Yellow Emperor's Nine-Ding Alchemy Classic, also known as the Yellow Emperor's Divine Alchemy Jue, is said to be the technique of the divine elixir given to Xuanyuan Huangdi by the Xuannv of the Nine Heavens.

There are 20 volumes of this Sutra, Su Hang counted it, and these 20 volumes of Alchemy Sutra really took up 20 bookshelves.

"Secret Code of the Three Emperors", "Taixuan Sutra", "Majestic Sutra of Zhengyimeng", "Decree of Immortals", "Nandou Sutra", "Beidou Sutra", "Taiping Cave Pole Sutra"...

Su Hang's breathing became a little short, this place is simply a Taoist treasure!

Even, in addition to Taoist classics, there are also many classics such as Confucianism, Mohism, and martial arts. This place is completely a library, a well-preserved library more than 2,000 years ago.

Any classic can probably benefit an ordinary person for life, not to mention that there are so many books hidden here.

Standing there in a daze for a long time, there is no doubt that this is what Zhang Daoling really left behind.

After regaining his senses, Su Hang immediately started to take action, cleaning up all the bamboo slips, as well as the rows of bookshelves, and put them all into the storage ring.
