The grand hall was empty.

There are tall shelves all around, on which many boxes are displayed. There are pearls flowing on them, and there are fluctuations of seals.

Some of the ancient boxes have been covered with a layer of dust, with obvious traces of time.

Some of the ancient boxes are full of demonic light, with dangerous warning signs beside them.

This is the Shennong hall.

At that time, Emperor Yan and Emperor Huang defeated Chiyou, also benefited from the help of the gods.

God has given them countless treasures, most of which have been consumed in the war, but a very small part has been left behind.

According to legend, this Shennong hall not only stores a large number of precious ancient medicines obtained by Emperor Yan from tasting a hundred herbs, but also collects these treasures left by Emperor Yan and Emperor Huang.

After stepping into Shennong hall, Luo Yu really noticed some unusual breath.

However, the first thing he did was to look for the Millennium Shenmu heart.

Soon, Luo Yu came to the shelf where Shenmu was stored and searched.

"It's just a piece of sacred tree trunk. It's useless!"

"It turned out to be a box of Shenmu fruits. It's a good treasure, but it can't compete with Shenmu's heart."

"It seems that this sacred wood heart was taken away after only 600 years of gestation. It's not enough to be a Taoist."

After a long time, the result is not satisfactory.

Although there are a lot of Shenmu materials in Shennong hall, including Shenmu heart, it can not meet the requirements of Luo Yu.

"Why! I found it

Finally, Luo Yu finds an ancient box on the top shelf.

After seeing through with the eye of heaven, Luo Yu showed a satisfied look.

"This sacred wood heart, with 1700 years of Taoism, is very suitable."

At the same time, Luo Yu felt a little bit tricky.

Obviously, this Shenmu heart is regarded as a treasure by the drug family, and it has been sealed layer upon layer. However, it has also secretly placed organs for fear of being stolen.

According to the custom, when the new medicine God came in to select the treasure, the organ should be closed to avoid hurting his own people.

But Luo Yu is obviously not his own person in the eyes of Yao family.

At present, instead of closing down, these organs are all on the alert.

In addition, on the top of the ancient box, there is a secret solid lock that seems to be made by a craftsman.

It's a pity that Luo Yu can't be defeated by these difficulties.

"Just a few stings, plus a nine son chain, also want to stop me."

Luo Yu uses his magic power to imprison the sting in the mechanism, and then takes down the ancient box.

The nine son chain lock on the ancient box has a complex internal structure and is closely linked. It is more difficult to crack than to piece together the magic cube. Moreover, if you make a mistake, you will lock it completely.

However, Luo Yu even cold jade thousand machine box is no matter, how can be a lock difficult to live.

With the strength of the spirit, he went into the lock cylinder and opened the ancient box.

It's a thousand years old.

"According to their rules, I can take two treasures with me once I come in. I can see the nervous look of those old things. There should be something more precious than the Millennium Shenmu heart."

Luo Yu put away Shenmu's heart and walked around with a smile.

After a few rounds, Luo Yu takes a fancy to a treasure medicine.

"It's no trace Buddha and bamboo. It's a good thing!"

Luo Yu looks through an ancient box hanging on the wall and finds that it is actually a section of golden bamboo.

This bamboo is very peculiar. At the joints, it looks like the Buddha of arhat.

This is the famous traceless Buddha and bamboo.

It originated from the pure land of Buddha kingdom in the West Tianling mountain, obviously not a mortal thing.

Luo Yu observed for a while and found that this section of traceless Buddhism and bamboo has reached the level of semi divine medicine, which is much more powerful than the ordinary nine grade treasure medicine.

Luo Yu is about to take this demigod medicine away and finish his trip to Shennong hall.

Suddenly, his outstretched hand stopped.

Luo Yu turns around slowly and looks at the thick wall behind him with a suspicious look on his face.

The location of this thick wall is very abrupt. It is neither close to the column nor connected with other walls. It seems that someone seems bored and builds a wall there.

Moreover, the bricks and stones on the wall are very simple, gray and white, which seems to have experienced a long time.

Luo Yu walked over and put his hand on it. In a flash, the scene of the vicissitudes of life and the endless flowing cup appeared in front of his eyes.

"It's a thing of archaic times!"

Luo Yu was surprised.

Originally, this wall did not belong here.

It was moved here later.

Luo Yu observed it with the eye of the book of heaven, but he failed to see through the internal situation.

"It's interesting that I can't even see through the eye of the heavenly book."

Luo Yu is more and more interested. With his current Taoism and the realm of the book of heaven, there should be many things that can't be seen through in the three realms, but it's not easy to appear in the human world.

In addition, after Luo Yu released his divine thoughts, he felt that there were nine seals left by Emperor Yan on the stone wall.

Moreover, someone should have tried to crack the seal before, but it didn't succeed.

"The last time I was in the underground palace, the memory of Emperor Yan didn't mention this stone wall to me. I didn't want to know whether it was forgotten or kept secret."

Luo Yu thinks that this stone wall comes from the archaic times, which is a very special time on the time axis of the mythological world.

The war between gods and demons, which later generations are fond of talking about, especially in awe, took place in the age of archaic disorder.

Luo Yu was born in Taichu, but because of the immortal cocoon before the flood and famine, he fell asleep for thousands of years and missed the flood and famine, Taigu, Shanggu and Fengshen times one after another.

Therefore, he knew very little about the archaic times, even a little strange.

The predecessor of Xiangxue's wife has experienced the age of archaic disorder. Unfortunately, the memory of Xiangxue's seven unique women has not yet been fully recovered, nor can she explain much to him.

The stone wall in front of us has been preserved since ancient times, and it was sealed by Emperor Yan himself.

There must be a big secret hidden in it.

However, Emperor Yan's nine seals are really powerful.

Luo Yu tried many methods, but at most he could only crack the eighth.

The last seal is obviously not the power of Emperor Yan.

Yan and Huang emperors, as the ancient ancestors of humanity, can be called the pioneers of the human race. From the perspective of the human race, they are certainly powerful.

But if the two emperors are compared in the long years of all living beings, they are not so outstanding.

Luoyu cast a spell, lighting up the ninth seal.

All of a sudden, a layer of shining runes appeared on the stone wall.

These runes are obscure, mysterious and ancient, but it can be seen that they were written by two ancient sacred masters.

Half of the rune pattern looks like the pulse of the earth, and half of the rune pattern has the flavor of the original form of the eight trigrams.

Luo Yu understood and thought to himself: "it's the seal they set together."
