Qin Yang's eyes were flat, if there was a chance, Shanhai Yijian would definitely make the same choice as him, so there was no mercy in his heart. What's more, he didn't think that Shanhai would die like this with a sword.

Continuing to walk forward for a while, Qin Yang's eyes narrowed slightly, and he vaguely felt that the richness of this aura was much better than the previous place, and the further he went, the richer the aura became.

After walking for a short time, he saw a brilliant purple light appear in front of him, which attracted Qin Yang's attention, because the light emitted by the lights was white.

His pace quickened a lot, and after turning a corner, he saw the source of the purple light.

I saw that the stone walls on both sides of this passage were inlaid with diamond-shaped crystals that shimmered with various colors, and the brilliant light illuminated the surroundings, and nearly two-thirds of the stone walls were shining with purple crystals.

Qin Yang felt the fluctuation of spiritual power from them!

"Master, this spirit crystal!" said the Yin-Yang Ice and Fire Beast as it appeared and looked around.

"Spirit crystals?" Qin Yang was taken aback, stared at these diamond-shaped crystals in front of him and said, "It is rumored that since the Seven Kingdoms were unable to step into the 100,000 Great Mountains, the spirit crystals disappeared, how could there still be spirit crystals in this place?"

The Yin-Yang Ice and Fire Beast smiled and said, "Master, most of you humans only know that after the Seven Kingdoms can't step into the 100,000 Great Mountains, many things will disappear, but you don't know why. ”

Qin Yang frowned and said, "Could it be that there is something hidden in this?" He had never delved into why the 100,000 Great Mountains separated the two places, and now it seems that it was probably because of some great things that happened in that distant era that many resources disappeared from the Seven Kingdoms, and this may also be the reason why the Seven Kingdoms and the other side of the 100,000 Great Mountains cannot communicate!

"This is because the Seven Kingdoms were regarded as a battlefield by Unai back then!" Qin Yang's words of the Yin Yang Ice and Fire Beast were taken aback, "Unai, isn't it possible that Unai is the name of the other side of the 100,000 Great Mountain, why do they want to use the Seven Kingdoms as a battlefield?"

"Master, don't be in a hurry. The Yin Yang Ice and Fire Beast said: "The Great War happened ten thousand years ago, when I was born not long ago, so I don't know everything, so I can only tell the master a rough idea." ”

Qin Yang lowered his head.

The Yin and Yang Ice and Fire Beast said: "Unai is as the master said, it is a title, just like the entire continent is named Tianfeng, the people of Unai call the place where they are located Unai, and its location is the center of the entire Tianfeng Continent, and the seven countries where the master is located are the edge of the Tianfeng Continent." ”

"And there are many marginal places like the Seven Kingdoms, they are called barbarian lands, before the people of Unai arrived, the people in the Seven Kingdoms did not know any cultivation methods, they were ordinary human beings. ”

"After the people of Unai arrived, they were given the method of cultivation, and the Seven Kingdoms entered the era of martial cultivation. ”

"Like your human martial arts, cultivation techniques, alchemy, and building equipment...... And so on are all given to you by the people of Unai. ”

"In that case, why would they treat the Seven Kingdoms as a battlefield?" Qin Yang asked suspiciously, cultivating a barbarian land and destroying it in a big war, which was obviously unreasonable.

The Yin Yang Ice and Fire Beast said: "I heard two rumors at that time, one was because there was a great battle because there was a martial god relic treasure in the Seven Kingdoms, and the other was that the people of Unai offended the supreme existence of the 100,000 mountains, causing it to be furious, and finally led to a decisive battle between the alien beasts led by the supreme being and the human race. ”

"But it's hard to say whether you'll win or lose today. The Yin Yang Ice and Fire Beast said: "If it is said that the people of the United States have won, they will never be able to step into the Seven Kingdoms again, and if it is said that the Supreme Being has won, it has never been out of the mountains for ten thousand years, otherwise the Seven Kingdoms have long been annihilated in the dust of history!"

"But no matter what kind of legend it is, it is the war that caused the disappearance of the resources of the Seven Kingdoms!" sighed the Yin-Yang Ice and Fire Beast.

Hearing this, Qin Yang's heart could not be calmed down for a long time, the world he had crossed over had such a past, and after a long time, he came back to his senses and said: "So, except for this place, there are no spirit crystals left in the rest of the place?"

"The Great War of that year caused too much damage to the Seven Kingdoms, causing the mountains and rivers to collapse, the leylines of the earth to overturn, the high-level spirit grass was almost extinct, and the spirit crystal was nowhere to be found. The Yin Yang Ice and Fire Beast muttered: "This place is underground, and I want to avoid it." ”

Qin Yang walked to a stone wall, stared at these crystals that were radiating light, and the Yin Yang Ice and Fire Beast said, "There is nothing special about the talent spirit crystal, as long as you are careful." ”

He took out a dagger from the storage medium and carefully began the mining work, which went smoothly without anyone bothering him. It's just that the speed is a little slow, and half an hour has passed, and more than 100 pieces have been mined, and this is still one percent of the amount of work.

Looking at the remaining crystals, Qin Yang's heart moved, and the ghost and demon spirit appeared in front of him.

He thought that the ghost and demon spirit were feeding on spirit crystals, so naturally they had done such work as mining spirit crystals, and it was better for two people to do it than for one person.

The ghost demon spirit glanced at him tiredly, unspeakably haggard, Qin Yang pointed around and said, "In the future, they will all be your food, but you have to find a way to mine them all." ”

"Chirp, chirp...... Ghost Zhao's dim eyes lit up slightly, it felt the breath of food, and when it looked down, it saw that Qin Yang's feet were all mined spirit crystals, and he raised his head to look at Qin Yang.

"Eat. Qin Yang said with a smile, the ghost and demon spirit got his permission, and excitedly drilled into the spirit crystal pile, and after a short while, he floated in the air with satisfaction, his eyes were bright.

"Why did you eat so little?" Qin Yang asked suspiciously, looking at the spirit crystal that was missing two pieces.

"The hosts. The Yin Yang Ice and Fire Beast looked at the Ghost Zhao Demon Spirit and explained, "Spirit crystals are divided into four grades: top, upper, middle, and lower. The number of spirit crystals sucked by the ghost demon spirit is related to the quality of the spirit crystals, like the top-grade spirit crystals it just smoked, and naturally two pieces are enough. ”

"And this is because it hasn't eaten for a long time, if it eats normally, it's basically a top-grade spirit crystal for half a moon. ”

The ghost Zhao demon spirit hid behind Qin Yang in fear, it was a foreign beast before its death, and the hierarchy system between different beasts was very clear, the Yin Yang Ice and Fire Beast was especially above it in terms of strength and talent, so it would be so afraid.

Qin Yang comforted for a while, looked at the colorful spirit crystals in the distance and quickly asked, "How do you distinguish them?"

The Yin Yang Ice and Fire Beast replied, "The ones that glow green are low-grade spirit crystals, the blue ones are medium-grade spirit crystals, the red ones are high-grade spirit crystals, and the purple ones are top-grade spirit crystals. ”

"Is it so easy to produce top-grade spirit crystals?"

The Yin Yang Ice and Fire Beast shook its head and said, "Purple spirit crystals are rare goods, just because the spirit crystals here have been unmined for thousands of years, and the spiritual energy is very prosperous, which makes this vein a superb vein, otherwise it would be impossible to generate so many purple spirit crystals." ”

The Yin Yang Ice and Fire Beast has survived for tens of thousands of years, and it has seen a lot of knowledge, and said eloquently: "So master, the purple spirit crystal is very precious, rare, if you give it a spirit crystal on weekdays, you can choose the middle and lower grades, and you don't have to use the top spirit crystal." ”
