Su Lijin is the ancestor of the Su family.

What era is he?

That was the figure before the founding of the Tang Dynasty!

But how many years have passed since his death?

At least four hundred years.

But Su Mu can still feel the gentle magnetic force on the iron sword!

And when Yunlu saw the iron sword, his whole eyes suddenly shrank!

"This ...... How is this possible!"

Yunlu has not cultivated for many years, but he has read a lot of books.

When Yun Hongmusk left him behind, at his request, he sent him a lot of books. As a dustless body, Yunlu at least before the Heavenly Man, there is no pressure to practice at all, so he likes to read miscellaneous books very much.

He has a deep understanding of various historical sources such as snake inscriptions, antiquity, and medievalism.

The star core, the world's top material, naturally he also knows something.

Though......

This iron sword is not at all inconspicuous, but the special energy attached to it is completely different from the five elements of gold, wood, water, fire, and earth, and it is not at all the spiritual power derived from the five elements like wind and thunder.

The most important thing is...... These special auras are not diluted at all. They wrap around the blade, releasing contractions, always round!

Yun Lu took the short sword, and his breathing became a little short!

He stretched out his hand, and the spiritual power surged, directly cutting the surface of the iron sword.

The sound of fingernails tearing iron made Su Mu's teeth a little sour, but he had a better understanding of Yunlu's strength in his heart.

This iron sword, even under the attack of Yu Ershen, was not damaged, but Yunlu actually just stretched out his fingers and broke the sword body!

And when the outer layer of iron leaks, the inside is a layer of tough, cooled pure gold.

No wonder it's so heavy!

Su Mu understood.

Nowadays, the upper-class monks, although they like spirit stones, do not refuse large quantities of gold and silver. It is because of this kind of yellow and white things in the world, there are even more strange and wonderful uses.

That is, it is possible to refine Adamantite Gold and Mithril.

Just like a piece of mortal iron, it has been beaten for thousands of years, and in terms of density, it will even surpass that of dark iron.

A large amount of gold and silver can be extracted from these two ancient metals.

Pure gold is widely used in formations and some armor treasures, this metal can perfectly isolate the aura, and even greatly weaken the power of the spiritual decision. Inside the iron sword, there is a layer of pure gold, which can be infused with spiritual power!

Mithril is the opposite, it is currently the best spiritual power conducting metal on the continent.

These two extracted materials are rumored to be related to ancient alchemy, but there are very few people who know it now.

It's just that Adamantite Gold and Mithril are more hard than Spirit Stones, after the Heavenly and Human Realm.

In fact, there is no difference between gold and silver, spirit stones, and pure gold and mythril.

are all trading equivalents.

Lower-level cultivators, earned gold and silver in exchange for spirit stone cultivation.

Middle-level monks began to use a large number of spirit stones to meet their own needs while trading.

For the upper level of the monks, the spirit stones were sufficient, and it was not even convenient to carry, so the necessities of pure gold and mythril, which were difficult to refine and easy to carry, began to become equivalents.

The value of this layer of pure gold alone in front of him is enough to exchange for tens of thousands of spirit stones!

And Yunlu carefully scraped the pure gold away, and a majestic magnetic force suddenly spread!

Su Mu only felt that his whole body sank!

The whole person seems to be two or three times heavier!

"This!?"

Su Mu looked at the sword body exposed under the pure gold in surprise.

In the gap that was scratched open, a purple black was revealed.

Pale blue spots of light swam and flickered in it, like an abyss, like the sky and the sea.

"This ...... This is the star core!"

Yun Lu took a deep breath, and then smeared the gap with pure gold, isolating the magnetic spiritual power.

"Childe...... Where did you get this sword?"

Su Mu shrugged his shoulders and said, "This sword has been in the Su family for at least four hundred years, and it was left by the ancestor of the Su family. ”

Yunlu nodded and said, "If you want to come to the ancestor of the Su family, you should be killed violently." Otherwise, he would definitely not fail to say anything about this star core. ”

Su Mu nodded.

Su Lijin disappeared suddenly, and it was similar to a violent death.

Looking at the way he hid the star core, he obviously recognized it, and sealed it with pure gold, thinking that it was of other uses. It's a pity that more than 400 years ago, with that Qianjing secret realm, there was no sound together.

"The eldest prince is really a celestial phenomenon, and such a treasure as the star core can be obtained. The old slave could then go back to the Yun family, because if he wanted to turn the star core into an organ, he needed at least a dozen celestial monks who had all-night alchemy to work together to polish it. However, with the eldest lady in the Yun family, she will be able to come back in two or three months at the earliest!"

Yunlu said excitedly: "There is a star core to do the eighth organ for Gongzi, and when Gongzi breaks through, he can directly cross the late stage of Lingyong and enter the Lingyuan!"

When Su Mu heard this, he nodded and said, "Okay." ”

In two or three months, if you break through the spirit yuan directly, you can still accept it.

I also need time to polish my swordsmanship and practice some spiritual determination at the same time.

Yunlu carefully put away the iron sword and took out a new blade from the storage bag.

The moment he saw the blade, Su Mu was stunned.

He knew the sword.

Every year on his mother's birthday, his father would paint a portrait of his mother holding this sword.

The edge is three feet, and the edge is an irregular blade, like an uneven level of canine teeth.

The entire body of the sword was covered with snake-like scaly protrusions, like the sharp teeth of some kind of creature.

"This is the Heluo sword, which is made of the bones of the Heluo fish, with the scales as the edge, and its essence and blood are boiled into soup and bonded. The river fish has a head and ten bodies, which is an ancient calamity. Those who are wounded by this sword are haunted by bad luck. After infusing the aura, it can be turned into a three-foot giant sword, and with every blow, it will absorb the enemy's aura! However, it should be noted that if you absorb too much aura, this sword will incarnate into a ten-tailed river luo, and it will be against the people and devouring the master. ”

Su Mu nodded and took it.

The tentacle sword body turned out to be warm!

What's even more bizarre is that the sword ...... There was a faint sound of heartbeat!

Yun Lu took out another jade slip and said, "This is the Candle Sky View, which is a pupil technique that can only be learned by the descendants of the Yun family." The old slave doesn't know the specific content. But if later, Childe performs this technique, it is best to do it privately, and he will wipe out everything. If it is discovered by someone with a heart, it may cause trouble. ”

"Hmm. ”

Su Mu took it, and Yunlu took out another pitch-black token.

Written on the token is a bright red word forgiveness!

Just by taking a look, Su Mu's heart trembled, he couldn't help himself!

It's like that blood-red word, like Tianwei!

"Wake up!"

Until Yunlu burst into tears!

Su Mu came to his senses in a cold sweat!

"This ...... What is this!?"

Just a little breath of the words almost immersed myself! The person who wrote this word ...... Who will it be!

Yunlu cautiously handed the token to Su Mu and said, "This is the Yama Luo Order." ”

"What's the use?"

"The old slave hopes that Gongzi will not need him in his life. ”

"Oh?"

Yunlu glanced at Su Mu deeply and said: "If the son does not meet the requirements, when the old slave kills the son, this order can ensure that the soul of the son can go directly to the Yama Palace, free from all crimes and customs, the soul will not be destroyed, and he will be reincarnated in the next life." ”

Su Mu was stunned, nodded, and put it away together.

Yunlu bowed deeply, looked at Su Mu and said: "Eldest son, the old slave has a word, I don't know whether to say it or not." ”

Say. ”

"Canglong took off, after the wind urging, rain rotting, fire, thunder punishment, and finally all the way to the waves, all over the body of the body, may still fall and cross the corpse. Maybe it's better to live in Chi Yuan and have a lifetime of freedom. ”

Su Mu chuckled when he heard this, and said lightly: "But, I am born and don't like to look up at people." It's better to fly higher. ”

Yunlu respectfully bowed: "The old slave understands. ”

"Please also ask the son to maintain his health with peace of mind, at most in March, the old slave will return and present the star dirt. ”
