After the flame snake died, it could no longer maintain its human form, and turned into a huge flame snake corpse in the blink of an eye.
Step by step, Li Fuchen took out the metal from the skeleton of the flame snake.
This flame snake provided 68 kilograms of bone marrow gold.
Bone marrow gold is much more precious than Wannian flame iron. A sword weighing more than a thousand catties can greatly increase the performance of the sword as long as it is mixed with ten catties of bone marrow gold.
"It's time to go back."
After digging out the Yan Snake's demon core, Li Fuchen glanced around and was about to leave.
"what!"
At the corner of the underground space, Li Fuchen saw a faint fiery red light.
When he walked over, Li Fuchen slapped it with a palm.
boom!
The rock burst, and a piece of metal the size of a calf exuding a fiery glow flew up.
Flame iron, and not ordinary hundred-year-old flame iron or thousand-year-old flame iron, it is clearly a piece of ten thousand-year-old flame iron.
Only Ten Thousand Years of Flame Iron will emit a fiery red light, and Thousand Years of Flame Iron will only glow with a faint red light.
This piece of 10,000-year flame iron is only the size of a calf, but its weight has reached an astonishing three thousand jin. It is a bit difficult for ordinary return to Yuan realm martial artists to lift it.
"A piece of 10,000-year flame iron plus some bone marrow gold can create an earth-level high-level weapon, but it's almost worth the money."
Hengjin can be called the most versatile metal in the world.
Its function is very simple, that is, to perfectly combine two or more metals without conflict.
At the same time, Hengjin is also one of the most expensive metals.
The Flame Snake Sword in Li Fuchen's hand weighed several thousand jin, but it was only mixed with less than one or two worth of gold.
Despite this, half of the value of the Flame Snake Sword is in the value of the gold, and the ten thousand years of flame iron and the gold of the bone marrow together account for only the other half.
"Maybe we can collect Ten Thousand Years Flame Iron."
Before Li Fuchen did not deliberately search for Yan Tie, mainly because there are too many Yan Tie Mountain Ranges. He simply doesn't like a hundred years of Yan Tie and a Thousand Years of Yan Tie. It is difficult to find Wan Nian Yan Tie. Now it seems that Wan Nian Yan Tie is estimated to be below the depth of several thousand meters or even ten thousand meters. The Spiritual Sense sweep range of the Douling Realm Grandmaster is generally only a few hundred miles. The more powerful ones can reach thousands of miles, and the more sky-defying ones may reach thousands of miles. in the air.
If it goes deep underground, the range of spiritual awareness sweeping will be reduced a hundredfold.
For example, it can sweep hundreds of miles in the air, but can only sweep a few miles under the ground.
To find Wannian Yantie in the depths of the earth, few people can do it.
However, Li Fuchen was different. Before he was promoted to the Douling Realm, Li Fuchen's spiritual awareness swept a range of 50,000 miles, which was comparable to a high-ranking king of Yuanhai Realm.
After being promoted to the Douling Realm, Li Fuchen's Spiritual Sense sweep range doubled to about 100,000 miles, which was comparable to some of the Yuanhai Realm high-ranking kings with exceptionally powerful Spiritual Sense.
Therefore, even if it is underground, the range of spiritual consciousness sweeping should be able to reach thousands of miles.
"Try it first."
Li Fuchen let go of his spiritual sense, testing the limit of the underground perception range.
Fifty miles.
A hundred miles.
A thousand miles.
One thousand eight hundred miles.
Perhaps because Li Fuchen's spiritual sense is relatively tyrannical, the range of underground spiritual sense perception has not been reduced a hundred times, only a little more than fifty times.
"I don't know what happens below the depth of 10,000 meters."
Li Fuchen's spiritual consciousness penetrated downward.
"It's so difficult. Within 10,000 meters underground, my spiritual sense perception range is one thousand eight hundred miles, and within 10,000 meters to 20,000 meters underground, my perception range is only tens of miles, and my perception range is only tens of miles below 20,000 meters. Several hundred meters."
Li Fuchen could sense that there was a strong force in the ground, and the deeper the ground, the stronger this strong force.
Li Fuchen estimated that this should be the law of the earth.
There are rules for everything.
It's just that ordinary things, the rule power contained in it is too weak to be sensed, and the earth is boundless, and the rule power generated by condensing together is extremely powerful, not to mention Li Fuchen, even if it is the emperor of the world, facing a The rules of the earth in the lower continents are helpless.
boom!
In this underground space, there is more than one piece of 10,000-year flame iron. Just now when Li Fuchen released his spiritual sense, he found three pieces of 10,000-year flame iron in this underground space.
The rock exploded, and Li Fuchen sucked out the third piece of iron.
This piece of Wannian Flame Iron is only the size of a palm, but it also weighs several hundred catties.
With a smile, Li Fuchen's spiritual sense penetrated 10,000 meters below the ground.
Although Li Fuchen's spiritual sense perception range is only tens of miles below 10,000 meters, it is enough. After all, the size of this underground space is only tens of miles.
One piece, two pieces...
There are more 10,000-year flame iron within 10,000 meters to 15,000 meters. Below this underground space, there are 70 10,000-year flame iron. The largest piece is about the size of Li Fuchen, and it is estimated to weigh tens of thousands of catties. .
It was a little troublesome to take it out. As a last resort, Li Fuchen drew out the Flame Snake Sword and cut a ravine with one sword. Some of them were too deep to split seven or eight swords or even dozens of swords.
"Forget it below 15,000 meters."
Li Fuchen would have to take a lot of effort to get the Wannian Yantai within 15,000 meters. Even if his spiritual sense could perceive it, he couldn't get it out at all. You must know here. The soil and rock of the country contain strong rules of the earth. It is impossible to cut a deep hole with a single sword like the ground.
Unless this underground space, there is a natural crack connecting below.
Unfortunately, this underground space does not have such natural cracks.
Back on the ground, Li Fuchen released his spiritual sense, looking for other underground spaces.
After a while, Li Fuchen found the second underground space.
The depth of this underground space is about 12,000 meters. Li Fuchen's spiritual sense only discovered its existence when he entered along the entrance of the underground space, but forcibly infiltrated from the surface of the earth, which consumes the spiritual sense too much, and there is no such thing. necessary.
In this underground space, Li Fuchen found a total of ninety thousand-year-old flame iron. The largest one was two pieces the size of him, and it weighed at least fifty thousand catties.
As time passed day by day, Li Fuchen gained more and more.
There is too much underground space in the Yantie Mountains that stretch for thousands of miles. Many of them are habitats dug up by the sixth-level monsters here. Of course, many of them are naturally formed, and there are some deeper underground spaces. Li Fuchen did not Dare to go in, the monsters or monsters living there are extremely powerful, and they are all monsters and monsters at the top master level. Although he is not afraid, it is impossible to kill them.
The fifteenth day.
In an underground space only 7,000 meters deep, Li Fuchen discovered a piece of 100,000-year-old flame iron.
This piece of flame iron is about the size of a washbasin, but it weighs more than twice that of ten thousand years flame iron, about fifteen thousand catties, and its surface emits a red hot light. This hot light is extremely domineering, Li Fuchen estimated So, even a warrior in the Heavenly Gang Realm who risked contact with one hundred thousand years of flame iron would be burned to death in a short period of time.
"The value of one hundred thousand years of Yantie is more than a hundred times that of ten thousand years of Yantie. Such a piece is estimated to be worth more than one hundred thousand contribution coins."
Of course, Li Fuchen did not intend to exchange it into contribution coins, after all, he did not lack contribution coins.
With this piece of 100,000-year-old flame iron, in the future, Li Fuchen can spend some contribution coins, and let the top refiner master or refiner king of the Red Rainbow Sect help build an earth-level top-tier sword.
