Chapter 531

After the death of the flaming snake, it can no longer maintain human form. In a blink of an eye, it turns into a huge flaming snake corpse.

Step by step, Li Fuchen took out the metal from the snake's skeleton.

The flaming snake provided 68 Jin of bone marrow gold.

The gold of bone marrow is much more precious than that of ten thousand years of burning iron. A sword weighing more than one thousand kilograms can greatly increase the performance of the sword if it is mixed with ten jin of bone marrow gold.

"It's time to go back."

Digging out the core of the burning snake, Li Fuchen glanced at it and was about to leave.

"Why

In the corner of the underground space, Li Fuzhen saw a faint red light.

When he walked over, Li Fuchen chopped off.

Bang!

The rock burst, and a piece of metal the size of a leg, glowing red, flew up.

Burning iron, and not ordinary hundred years of burning iron or thousand years of burning iron, is clearly a piece of ten thousand years of burning iron.

Only ten thousand years of burning iron will emit a red light, and the thousand year burning iron is only suffused with a light red light.

The ten thousand year old iron is only the size of a leg, but it weighs an astonishing 3000 Jin. It's hard for ordinary martial artists to lift it.

"A piece of ten thousand years of burning iron and some bone marrow gold can make a high-level weapon at the prefecture level, but it almost weighs gold."

Hengjin is the most versatile metal in the world.

Its function is very simple, that is to combine two or more metals perfectly without conflict.

At the same time, Hengjin is one of the most expensive metals.

The flaming snake sword in Li Fuchen's hand weighs thousands of Jin, but it is only mixed with less than one or two Heng gold.

However, half of the value of the burning snake sword lies in the balance of gold. The gold of ten thousand years' fire iron and bone marrow accounts for only the other half.

"Maybe we can collect the ten thousand years of burning iron."

Li Fuchen didn't deliberately look for Yantie before. The main reason is that there are too many burning irons in the Yantie mountains. He can't look at the burning iron in a hundred years, and it's hard to find it. Now, it seems that the Wannian burning iron is estimated to be thousands of meters or even tens of thousands of meters below the ground. The scope of the spirit sweeping of the master of the fighting spirit realm is only a few hundred miles, and the more severe one can reach thousands of miles, It may be thousands of miles, but it's in the air.

If you go deep into the earth, the scope of spiritual sweep will be reduced by a hundredfold.

For example, it can sweep hundreds of miles in the air, but only a few miles under the ground.

There are few people who want to search for Wannian iron in the deep underground.

However, Li Fuchen was not the same. Before he was promoted to doulingjing, Li Fuchen's spiritual awareness swept 50000 Li, which was comparable to the high-level king of Yuanhai realm.

After he was promoted to doulingjing, Li Fuchen's scope of soul sweeping doubled to about 100000 Li, which was comparable to some high-level kings of Yuanhai realm with extremely strong spiritual sense.

So even under the ground, the scope of mind sweeping should reach thousands of miles.

"Try it first."

Li Fuchen let go of his spiritual consciousness and tested the limit of the underground perception range.

Fifty Li.

A hundred miles.

A thousand miles.

One thousand eight hundred Li.

Perhaps because Li Fuchen's spiritual consciousness is more powerful, the perception range of underground spiritual consciousness has not been reduced by a hundred times, only a little more than 50 times.

"I don't know how deep it is below 10000 meters."

Li Fuchen's spiritual consciousness penetrates downward.

"It's very difficult. Within 10000 meters under the ground, my spiritual perception range is 1800 miles. Within 10000 meters to 20000 meters underground, my perception range is only dozens of miles, and it is estimated that it is only a few hundred meters below 20000 meters."

Li Fuchen can sense that there is a powerful force in the ground. The deeper the earth is, the stronger the power will be.

Li Fuchen estimated that this should be the rule of the earth.

Everything has rules.

It's just that ordinary things contain too weak rules that can't be sensed. However, the land is vast and boundless, and the rule power generated by condensation is extremely powerful. Let alone Li Fuchen, even the emperor of FA Xiangjing has no choice but to face the earth rules of a low-level continent.

Bang!

In this underground space, there is not only one piece of Wannian burning iron, but three pieces of Wannian burning iron were found in this underground space just now when Li Fuchen released his spiritual consciousness.

The rock exploded, and Li Fuchen sucked out the third piece of Wannian iron.

The ten thousand year old iron is only the size of a palm, but it also weighs several hundred jin.

With a smile, Li Fuchen's spiritual consciousness went down to ten thousand meters below the ground.

Although under 10000 meters, Li Fuchen's spiritual perception range is only tens of miles, but it is enough. After all, the size of this underground space is only tens of miles.

One, two

There are more Wannian irons within the range of 10000 meters to 15000 meters. There are seven pieces of Wannian iron under this underground space. The largest one is about the size of Li Fuzhen and weighs tens of thousands of Jin.

Li Fuchen pulled out the flaming snake sword. With one sword, he cut a gully. If some were too deep, he had to chop seven or eight swords or even dozens of swords."Less than 15000 meters is enough."

Li Fuchen had to work hard to get the ten thousand year old iron within fifteen thousand meters. Even if his spiritual sense could sense it, he could not take it out at all. We should know that the soil and rocks here contain strong rules of the earth, and it is impossible for any sword to cut a deep hole like the ground.

Unless there's a natural crack in this underground space that connects below.

Unfortunately, there is no such natural crack in this underground space.

Returning to the ground, Li Fuchen releases his spiritual consciousness and seeks other underground spaces.

After a while, Li Fuchen found a second underground space.

The depth of this underground space is about 12000 meters. Li Fuchen's psychic consciousness only found its existence when he entered through the entrance of the underground space. However, it was too consuming and unnecessary for Li to infiltrate from the surface.

In this underground space, Li Fuchen found nine pieces of ten thousand year old iron. The largest one was two times his size and weighed at least 50000 Jin.

As time went by, Li Fuzhen's harvest was more and more.

There are too many underground spaces in the Yantie mountains, many of which are the habitats dug up by the six level monsters here. Of course, many of them are naturally formed. There are also some deeper underground spaces. Li Fuchen did not dare to enter. The spirits of the demons or demons living there are extremely powerful. They are clearly demons and demons at the top master level. Although he is not afraid of them, he is not afraid of them, But it's impossible to kill.

The fifteenth day.

In an underground space only 7000 meters deep, Li Fuchen found a piece of 100000 year old burning iron.

This flaming iron is the size of a washbasin, but its weight is more than twice that of ten thousand years' burning iron, which is about 15000 Jin. Its surface emits a red burning light, which is extremely domineering. Li Fuchen estimates that even a martial artist in Tiangang would be burned to death in a short period of time if he was exposed to the burning iron for 100000 years.

"The value of one hundred thousand years of burning iron is more than one hundred times that of ten thousand years of burning iron. Such a piece of iron is estimated to be worth more than 100000 yuan."

Of course, Li Fuchen didn't intend to convert it into contribution currency. After all, he didn't lack contribution currency.

With this one hundred thousand year old burning iron, Li Fuchen can contribute some coins to make a prefecture level top level sword with the help of the top weapon refining masters or the weapon refining king of the Chihong clan.
