After that, Ye Guchen, led by Xu Zhiqing, went to the secret mine.
Along the way, Xu Zhiqing also briefly discussed some kendo topics with Ye Guchen.
Although Xu Zhiqing was not from the Sword Dynasty, he still used swords, so he and Ye Guchen got along quite well.
This made Yang Haolie's eyes always have a slightly gloomy look.
Xu Zhiqing was born into a noble family of the Yunlan Dynasty and had a strong background.
Yang Haolie has always been interested in Xu Zhiqing, and this time they were wandering together in the ancient wasteland. He also had the idea of getting close to Xu Zhiqing. If possible, it would be best to win.
But unfortunately, Xu Zhiqing has a cold personality and is not weak in strength, so Yang Haolie cannot be strong.
As for Liu Ru, she likes Yang Haolie, but unfortunately she is inferior to Xu Zhiqing in terms of status, cultivation and appearance, so she cannot be favored by Yang Haolie.
Two days passed, and Ye Guchen finally saw the secret mine that Xu Zhiqing and others mentioned.
The Nami Mine is located in a mountain range, surrounded by grass. There is a cave hidden deep inside, with a deep entrance, like a huge mouth of a wild beast.
"There is a secret mine containing mica." Xu Zhiqing said in a low voice.
"Oh, are there monsters in the secret mine?" Ye Guchen couldn't help but ask, looking at the cautious appearance of Xu Zhiqing and others.
"There may be a sixth-order death worm king in that secret mine." Yang Haolie said with a slightly cold tone.
They had been surrounded by a swarm of death worms before, and the reason why they did not use their trump card was to deal with the sixth-level death worm king that might appear in the secret mine.
"Sixth level monster?" Ye Guchen's eyebrows condensed slightly.
Sixth-level monsters are equivalent to the divine realm of humans.
No wonder Xu Zhiqing, Yang Haolie and others looked like they were facing a formidable enemy.
But for Ye Guchen, there is no problem in retreating calmly, not to mention whether he can beat the sixth-level monster.
"Brother Dugu, the secret mine is very dangerous. Are you sure you want to enter?" Yang Haolie suddenly asked.
Liu Ru and Zhou Yan also looked at Ye Guchen in unison.
Obviously, in their eyes, Ye Guchen's fifth-level strength would only be a hindrance even if he entered the secret mine.
Xu Zhiqing was also slightly hesitant. It was not that she disliked Ye Guchen's low strength, but felt that Ye Guchen might be in danger if he entered it.
"Sir, there may be great danger in that secret mine..." Xu Zhiqing hesitated.
"You don't have to worry about me then." Ye Guchen smiled lightly.
Now that he has encountered this secret mine, how could Ye Guchen give up entering it?
As long as there is a possibility of the existence of thousand-year-old mica, Ye Guchen will not miss it.
"Since Brother Dugu asks so, let's go together. But when the time comes, we may not be able to take care of you." Yang Haolie smiled indifferently.
Although Ye Guchen came to their rescue, Yang Haolie and Liu Ru did not have a good attitude towards Ye Guchen.
Weak people are born to be looked down upon.
Ye Guchen didn't say anything, his eyes were indifferent.
Soon, a few of them held their breath and entered the secret mine cave.
As soon as he entered it, Ye Guchen felt a cold air.
The cave was deep, and after they went a hundred feet deep, they were surrounded by spots, with many strange ores shining with brilliance.
"Chalcolite, fluorite, virtual crystal iron..." Ye Guchen murmured to himself.
There are many rare ores in this dense mine.
"Young Master knows so much about metal ores, could it be that he is also involved in casting?" Xu Zhiqing was slightly surprised.
"That's right." Ye Guchen said with a smile.
Casting is considered a side job for him.
"It turns out that Brother Dugu is a foundry master. No wonder his cultivation is a little mediocre and most of his energy is focused on casting."
Seeing Xu Zhiqing and Ye Guchen talking, Yang Haolie felt a knot in his heart, and his tone couldn't help but be a little sarcastic.
"Yang Haolie, that's enough. Mr. Dugu came to our rescue."
Hearing Yang Haolie's words, Xu Zhiqing frowned.
Yang Haolie remained silent, but the coldness in his eyes became more concentrated.
Within a moment, Ye Guchen and others also went deep into the secret mine.
Ahead, a hissing sound suddenly came.
There seemed to be foreign objects crawling in the underground soil.
Everyone paused, Xu Zhiqing's jade sword was pulled out, and a powerful zhenqi condensed in the body, and then all gathered on the sword's edge.
She stabbed with her sword, and thick, turbid blood burst out from the soil.
Xu Zhiqing's sword directly penetrated a death worm.
"It seems that they all had their own clumsiness before." Ye Guchen thought to himself when he saw this scene.
Even if he didn't take action before, if they were forced into a desperate situation, Xu Zhiqing and others might have the ability to break out, but they just didn't want to waste their energy at that time.
"Everyone, be careful." Xu Zhiqing whispered.
After traveling for a while, some light white ore appeared on the cave wall ahead.
"It's mica..." Yang Haolie and others' eyes lit up.
This mica is really the rare mineral they are looking for.
However, most of these mica are hundreds of years old. Although rare, they are not the most precious.
"In the deepest part of that dense mine, there must be millennium mica." Yang Haolie became more and more certain.
Afterwards, everyone began to collect mica.
Although these mica have only accumulated for hundreds of years, they are still rare treasures.
Ye Guchen also collected some, but these mica did not help much in repairing the Nine Dragons Thunder Prison.
Repairing the Kowloon Thunder Prison will require at least a thousand years of mica.
Everyone collected mica along the way and went deep into the dense mine.
One or two dead worms occasionally appeared along the way, but they were all dealt with easily.
"Stop!"
Xu Zhiqing suddenly whispered, and everyone stopped immediately.
Because in front, there were seven or eight death worms coiled like snakes, as if they were resting.
The auras of those death worms are all at the peak of the fifth level, which is equivalent to seven or eight masters at the peak of the ninth level of Tiandi Lingqiao.
More importantly, there are several pieces of snow-white ore among the death worms.
"Thousand-year-old mica!" Yang Haolie and others' breathing became rapid.
Ye Guchen's eyes also focused.
"According to plan, let's go!"
Xu Zhiqing and others did not hesitate and took action directly.
By this time, they had no reservations and fully demonstrated their strength.
Yang Haolie's whole body was filled with purple-red blazing flames, which spread towards the death worms.
"The strange fire of heaven and earth?" Ye Guchen did not expect that Yang Haolie also possessed the strange fire of heaven and earth.
The power that the death worm fears the most is strange fire and thunder.
Not only that, Yang Haolie also used a flaming sword, and the power sealed in it was released, and the power of each sword was extremely powerful.
In addition, Zhou Yan, Liu Ru, and Xu Zhiqing also used their own methods.
Ye Guchen was the most leisurely one and did not take any action.
Soon, with the tricks of Xu Zhiqing, Yang Haolie and others, the seven or eight death worms were also killed.
Yang Haolie and others also collected thousand-year-old mica.
"Master Dugu, this piece is yours." Xu Zhiqing handed a piece of thousand-year-old mica to Ye Guchen.
Ye Guchen accepted it without any politeness.
Yang Haolie and others frowned slightly when they saw this, but since Xu Zhiqing gave it away personally, they couldn't say anything.
"It seems that we are lucky this time and did not encounter the sixth-level death worm king." Zhou Yan said with a smile.
"It shouldn't be..." Xu Zhiqing thought.
At this moment, Su Qingyu's voice came from Ye Guchen's heart.
"There are good things behind that rock wall..."
"Well, could it be..." Ye Guchen's mind moved.
He thought for a moment and did not move Xu Zhiqing and others away.
Because if Ye Guchen guessed correctly, the sixth-order Death Worm King was behind the rock wall.
And what the sixth-level Death Worm King protects is by no means as simple as thousand-year mica.
