Hearing Su Han's words, Lu Xuan's eyes closed and he passed out.

After treating his injuries, he was carefully carried into the house, and the group retreated.

The two old men still glared at Su Han angrily, obviously thinking that the culprit who injured Lu Xuan was Su Han.

Even though he was injured in this explosion, in fact, the main reason was that Lu Xuan's own protection was not in place.

Every time he experimented, he had to protect himself very tightly and wear all kinds of protective gear, but this time, Xu was so excited after being instructed by Su Han that he didn't even wear armor.

Su Han had nothing to say about the attitude of the two old men.

They don't have any bad intentions, they like it, they hate it, they hate it, everything is written on their faces, but they get along well.

As long as he develops the Thunder Breaking Yuan Arrow by himself, and then waits for Lu Xuan's health to recover, naturally everything will be done.

After returning to the room, seeing Su Han's frowning face, several people were a little worried in their eyes.

After all, although he knew Su Han's ability very well in his heart, could Su Han do what even Lu Xuan couldn't successfully develop?

In case of......

If it fails, the conflict will definitely erupt.

Manman waved his hand, and several people pushed out the Lu with interest, and Manmanlian moved lightly, walked in front of Su Han, and gently rubbed his shoulder, "Is it difficult?" ”

Su Han nodded lightly.

"Don't be in a hurry, I trust you." She whispered.

Su Han shook her backhand, gently held her hand, and squeezed it a few times.

After being silent for a long time, Su Han stood up, "I'll go check some information, I always feel that something is wrong, but I don't know where this feeling comes from." ”

"I'll go with you."

"Okay."

The two went out and found Linglong, and Su Han asked, "Can I go to the Library Pavilion to have a look?" ”

Linglong hesitated, and there was embarrassment in her eyes.

In this Immortal Valley, the Library Pavilion is definitely the most important place, the inheritance and classics of the Immortal Heaven for thousands of years can be found inside, and many of them are original and unique books, but those outside are circulated and lost.

To be honest, Su Han did not have this qualification.

It's just that the current situation ......

"You can send someone in to supervise me, I will check some historical records, and I will definitely not use the exercises." Su Han added quietly.

Glancing at Su Han deeply, Linglong nodded lightly this time, and walked towards the bamboo forest behind the wooden house with Su Han.

As early as when Su Han first entered the Immortal Valley, this bamboo forest was told that it was a forbidden place, and a few people didn't break in these days, even if they wanted to, they couldn't break in at all.

Here, however, there is an extremely powerful formation protection.

Su Han quietly investigated, this formation, the defense is extremely powerful, and its energy source seems to be a steady stream of heaven and earth aura in the entire valley.

With his own strength, even if he can barely open it, it will take at least a few months, and the shock caused is even greater.

Standing in front of the bamboo forest, Linglong took out a jade pendant from his arms, threw it casually, and the jade pendant shone brightly in mid-air, and a gate phantom suddenly appeared on the formation barrier, and there was a depression on the phantom.

The jade pendant was tightly attached to the depression, and the entire formation suddenly appeared a road that could accommodate one person.

The three of them walked in.

In this formation, although it looks like a bamboo forest from the outside, the scene is completely different when you walk inside.

An antique pavilion, carved dragon and carved phoenix, extremely exquisite, divided into three parts, Dan Pavilion, Instrument Pavilion, Book Pavilion.

The three of them entered the book pavilion, rows of bookshelves were lined up, a strange fragrance lingered in the air, and some phantom shadows flickered.

Su Han wasn't too surprised.

This shows that there are some exercises here that are extremely powerful, and they are also written with special materials, or even with the soul power of the strong themselves, for future generations to understand.

"The history books are in the back ten bookshelves, and everything that happened in the Blood Moon Continent can basically be found out from it." Linglong spoke.

"Help me find it, find out all the information about the Thunder Breaking Yuan Arrow in the history of the Blood Moon Continent." Su Han explained, and he acted quickly.

With the sound of the pages turning, time flies by.

It seems that there is never darkness here, there is always a faint light shining in, and there is no change of time.

I don't know how long it has been, Su Han's eyes are sour, and his face is pale, after all, there are not only books here, but also some jade slips, rubbings and the like, all of which must be viewed with soul power.

And after such a long time, Su Han probably found out clearly.

Thunder Breaking Yuan Arrow, on the Blood Moon Continent, has another name, God Slaughter Arrow.

Although, in everyone's mind, that blood wolf was an evil and powerful existence, at the same time, everyone regarded it as the only god in the history of the Blood Moon Continent.

Under God, it is the martial saint.

Su Han sorted out all the records about the Thunder Breaking Yuan Arrow.

This kind of arrow is said to have been given from the sky by a martial saint powerhouse, who communicated with his predecessors who had already crossed the tribulation and ascended.

At that time, there were a total of twelve, and at that time, the human race was facing a decisive battle with the blood wolf, twelve, and the six martial saints at that time, one person and two, were fairly distributed.

In the battle of Blood Wolf Mountain, a total of six god-slaughtering arrows were used, and the remaining six were passed down from generation to generation, and for a long time, there was no information about it.

Based on this information, Su Han probably deduced that the blueprint of the Thunder Breaking Yuan Arrow in Lu Xuan's hand was definitely fake.

I don't know where he got it, but I think it was deliberately spread by some people with ulterior motives.

The next account of the God Butcher Arrow is very simple.

30,000 years ago, located in the extreme south, in the depths of the Wuji Sea, the contemporary Wuji Martial Saint, when the sect was about to collapse, used a god-slaughtering arrow, that arrow, consumed all the energy savings of the Wuji Gate, the Wuji Gate was completely destroyed, the Wuji Martial Saint also died on the spot, and the two Martial Saints who besieged the Wuji Gate were also killed and injured.

Twenty-five thousand years ago, another God Slaughter Arrow was found in a place called Tianzhu Peak, more than a dozen Martial Saints flocked to it, experienced a fierce battle, and was taken by the first Martial Saint Starry Sky Martial Saint at that time, and the Starry Sky Martial Saint later broke through the sky and soared, this arrow was carried by him.

18,000 years ago, the third God Slaughter Arrow was in the hands of the emperor of the Great Qian Dynasty, and the Emperor of the Qian Dynasty used one in the battle with the barbarian demon clan, and one arrow pierced through the three demon emperors, and the Qianjun won a great victory, laying the foundation of thousands of years.

When Emperor Qiandi was in power, he ordered to search the entire Blood Moon Continent, use the strength of the whole country, find the other two god-slaughtering arrows, and destroy them in public, indicating that the world is peaceful and there is no need for such murder weapons.

As for the last one, it is also related to the Great Qian, in the later period of the Great Qian Dynasty, there was a mysterious dynasty of Great Xia, which rose to destroy the Great Qian Palace with the last arrow of slaughter on the Blood Moon Continent, and destroyed the Great Qian Palace with one arrow, after that, the Great Qian fell apart, and the dynasty era ended completely.

Even if Great Xia destroyed the Great Qian, after all, it failed to become the next Great Qian, and after nearly a thousand years, he was killed by a strong man named the Seven Killing Martial Saints.

Since then, there has been no dynasty in the Blood Moon Continent, but there are many martial arts sects, and the current pattern has finally formed.

……

After reading all this, Su Han had a general understanding of the historical development of the entire Blood Moon Continent in his heart.

This is no different from the path taken by many Xiuzhen civilizations.

And what interested Su Han the most was that in the entire Blood Moon Continent, there were only the first twelve God Slaughter Arrows, that is, the Thunder Breaking Yuan Arrows.

Since then, no one has been able to develop it.

No wonder, Lu Xuan was so keen on researching this weapon that he didn't even care about his life.

What is it for?

The great road goods of the fairy world, when they arrived on this Blood Moon Continent, they turned out to be the most scarce materials?

Su Han was puzzled in his heart.

In all fairness, the manufacturing process of the Thunder Breaking Yuan Arrow is not too complicated, even if it is three formations, with the current formation level of the Blood Moon Continent, it should not be able to be studied.

But for thousands of years, there will always be some amazingly brilliant and brilliant weapon masters, who should be able to think of other ways.

But why is it the way it is?

Even, he clearly told Lu Xuan about the manufacturing process, but he still couldn't develop it.

Su Han meditated here, and the vines stood quietly aside, and Linglong was still rubbing the statue carved by the spirit of the demon beast.

By this time, the two of them were fine.

"Let's go, let's get out of the house first, and let me think about it again." Accidentally looking up and seeing the idleness of the two of them, Su Han sighed softly and walked out with his feet raised.

Linglong sighed, casually weighed the demon beast spirit, put it in his pocket with great satisfaction, and strode forward.

"Wait!"

Seeing her movements, seeing the demon beast spirit in her hand, Su Han seemed to suddenly remember something, and extreme surprise appeared in his eyes.

Taking out an immortal stone casually, Su Han said, "Linglong, have you seen this kind of thing?" ”

Seeing this immortal stone, Linglong's eyes couldn't be taken off at once.

The demon beast spirits on the Blood Moon Continent are generally colorful, and there is basically no pure and transparent.

Moreover, she could feel that the stone in Su Han's hand contained extremely pure and powerful power, especially its appearance, which was so beautiful!

Frowning and thinking for a while, Linglong shook her head.

"That's it!"

Su Han clutched the immortal stone tightly and screamed all at once.

I have overlooked one of the simplest problems, which is energy.

The reason why the Thunder Breaking Yuan Arrow can produce such a powerful power is because there are nine of the purest immortal stones in the magic circle, providing energy.

On the Blood Moon Continent, it is impossible to produce such a thing as immortal stones!

The immortal realm is the highest level of the plane, where it is not the aura of heaven and earth, but the immortal qi, which involves the origin of the plane, Su Han does not know the reason for the Dao, only the result of the Dao.

Every time Lu Xuan researches, he uses the demon beast spirit as the energy core, no wonder it explodes.

Even if there is a huge amount of power in the spirit of the demon beast, how can it be compared to the immortal stone?

"I've found a way, let's go, let's get out!"

Su Han couldn't wait to rush towards the door.
