The two of them didn't know that Li Qian, Qingwan and others spoke highly of them.
At the same time, everyone was worried about them.
About six hours later, Ji Tianxing and Yunyao flew 70,000 miles and finally left the outer area of the Flame Mountain.
Entering the central area, the two people clearly felt that the flames between heaven and earth were more raging, and the temperature had nearly doubled.
In order to maintain the mana shield, their mana consumption speed is also much faster.
But at this moment, Ji Tianxing suddenly stopped flying and landed on a pale golden mountain peak.
Yun Yao followed over and asked with concern: "Tian Xing? What's wrong? Do you want to stop and adjust your breathing for a while?"
Ji Tianxing shook his head and said with a smile: "That doesn't mean... I may have almost found what I want."
Yunyao was startled for a moment, then showed a look of surprise and asked: "Are you talking about... the materials for repairing the divine sword?"
"That's right." Ji Tianxing nodded, pointed to the mountain peak at his feet, and said, "I came all the way here and carefully explored it with my spiritual sense.
Almost every mountain peak contains a large amount of metal components, and there are some mineral veins buried underground.
Although many mineral veins are rare and can yield priceless ores, I am too lazy to waste time.
I just discovered that there are three mineral veins hidden in the mountain below us, one of which is the Jinwu Copper Mine."
Yunyao immediately understood what he meant, "Jinwu copper mine is rare and rare, and any piece of ore with higher purity can be sold for a sky-high price of 100,000 spirit stones.
However, the formation conditions of Jinwu copper deposit are very special and the growth is extremely slow.
Even a mineral vein that has grown for thousands of years may only be a hundred feet long.
Only a Jinwu copper mine that has grown for tens of thousands of years can produce a piece of Jinwu copper marrow!"
Ji Tianxing showed a smile and nodded: "Absolutely correct! I just checked and found that the length of the Jinwu copper mine in this mountain seems to be more than a thousand feet!"
"Thousands of feet long?" Yun Yao blinked her beautiful eyes, revealing a look of deep anticipation, "That must be a mineral vein that has grown for over ten thousand years, and there is a certain chance of producing golden black copper marrow!"
"Let's go in and take a look." Ji Tianxing said as he held out the Heaven Burial Sword in his right hand.
When he saw no one around, he took Yunyao and flew to the middle of the mountain.
Then, he found a mountain wall closest to the mineral vein, swung his sword and thrust out several rays of sword light.
“Bang bang bang!”
Four dazzling golden sword lights struck the pale golden mountain wall fiercely.
Suddenly, a large hole was punched out of the glass-like mountain wall. The opening was two feet in diameter and about twenty feet deep.
The two of them got into the deep cave, with Ji Tianxing holding his sword to open the way ahead.
He used his sword skills three times to dig the cave a hundred feet deep before entering the heart of the mountain.
The belly of this mountain peak is hollow and full of large and small caves, all naturally formed.
The Jinwu copper mine Ji Tianxing was looking for was located in a huge cave with a radius of three hundred feet.
The floor of the cave, the roof of the cave and the surrounding rock walls all appear dark red, mixed with metallic luster.
The air was extremely hot, and the cave was filled with raging waves of fire, enough to melt the soul-level magic weapon.
Ji Tianxing and Yunyao were in the cave and had to double their mana to maintain the operation of the shield and resist the burning of the spiritual fire.
I saw that the cave was full of jagged rocks and the ground was covered with mounds, rock piles and potholes.
Rows of pale golden stone milk hang upside down from the ceiling, like a forest of spears.
A vein of more than three hundred feet long, dark golden in color, lying on the ground like a giant dragon.
This is exactly the Jinwu copper mine Ji Tianxing is looking for.
The mineral vein extends from one end of the cave to the other, just across the entire cave.
Neither the origin nor the end of the vein can be seen, and its exact length is unknown.
Most of the veins are buried underground, and only a small part is exposed above the ground, but it is still ten feet high.
The dark golden mineral veins exude a mysterious and ancient atmosphere, as well as a terrifying and scorching high temperature.
Ji Tianxing and Yunyao both stared at the Jinwu Copper Mine and used their spiritual senses to explore it carefully.
"Judging from the condition of this mineral vein, it should be more than ten thousand years old, and it has been refined by the glazed sky fire to be very pure.
I just don’t know if there is any golden black copper marrow produced in the veins?”
Yun Yao thought for a while and said: "Tian Xing, let's search separately to save time. You go north and I go south."
Ji Tianxing nodded in agreement, and then searched north along the mineral veins from the middle of the cave.
Yunyao turned her back to him and searched southward along the veins.
There was silence in the cave, and the two of them concentrated on searching.
Soon, a quarter of an hour passed.
The two of them arrived at both ends of the cave, but were blocked by rock walls.
However, neither of them found the Golden Black Copper Marrow.
Ji Tianxing sighed with some disappointment, "This mineral vein is a thousand feet long, and more than half of it is buried in the mountain. We can only use secret methods to drill into the mountain to explore."
Yunyao comforted her: "Don't be discouraged. This vein has been growing for thousands of years and is very rare on the mainland. It is likely to have given birth to golden black copper marrow.
Although it is a bit troublesome, we have plenty of time, so we can just take our time."
Afterwards, the two continued to act separately.
The two of them used secret techniques to drill into the rock layer and groped along the Jinwu Copper Mine to the north and south ends.
The mountain body has been burned by the glazed sky fire for tens of thousands of years, and is as strong as the top-grade magic weapon of the Yuan Shen.
If two people use the divine sword to dig a cave along the mineral veins, it will definitely take a lot of effort, which will consume time and energy.
However, they used the secret method of escape from the earth to shuttle through the mountain at a very slow speed, which was similar to that of ordinary people walking.
Time passes silently.
Soon, half an hour passed.
Ji Tianxing traveled three hundred feet through the mountain and reached the end of the Jinwu Copper Mine, but still could not find the Jinwu Copper Marrow.
So, he turned back and passed through the cave to meet Yunyao.
As soon as he passed through the cave, he received a message from Yunyao's spiritual consciousness.
"Tian Xing, come and see! I found it!"
Yun Yao's tone was quite happy and a little excited.
Ji Tianxing was startled for a moment, then hurriedly got into the mountain and used all his secret skills to rush over.
When he found Yunyao, he saw Yunyao in the rock layer, guarding a stone hill with a radius of several tens of feet.
The Jinwu Copper Mine ends here, and that huge stone hill is obviously the origin of the vein.
Ji Tianxing followed Yunyao's guidance and released his spiritual consciousness to explore the stone mound.
I saw a mass of half-black and half-gold ore deep in the dark golden stone mound.
The ore was as big as a head, with a rhombus-shaped surface and a light black golden light, making it look extremely mysterious.
The metal and power contained in it far exceeds that of the entire mound!
There is no doubt that this is the golden black copper marrow he has dreamed of!
