The one who had snuck into the mine was Ye Lingyue.

The Song family’s mine at that moment used to be Ye family’s mine. Ye Lingyue found the topographic map of the mine from the stone house and memorized it.

With the cover of the night, she successfully infiltrated into the depth of the Song family’s mine.

Compared to the Seven Northern Hill mine, this mining area was smaller by 20 to 30%, and the quality of the ores was not as good. However, with the help of Master Lian, the Song family could refine the dark iron of 50% purity.

“Since you dared to use the frozen grass against the Ye family, I will let you have a taste of what it feels like to be deceived.” A smile appeared on Ye Lingyue’s lips.

She took out several bottles of potions from her arms. These potions were not ordinary goods.

After Ye Lingyue had moved a thousand frozen grass to Hongmeng Sanctuary, it took ten days to cultivate them into ten-year-old ones.

Ye Lingyue then refined all these 10-year-old frozen grass into ice poison.

Master Lian was in a hurry and those frozen grass he planted on Seven Northern Hill were only around a year old. Although those frozen grass could make a dark iron ore rust, the rust only grew on the surface and didn’t affect the quality of the ore.

But if they stained the dark iron ore with the ice poison in her hand, not only would the rust be growing.

Ye Lingyue poured the ice poison onto a piece of iron ore and in a blink of an eye, a piece of iron ore completely corroded. Not only that, but the soil touched by the ice dew also turned rusty red.

As long as ice poison covered the Song family’s entire mining area, it would become a wasteland and nothing would grow on it from then on.

Ye Lingyue’s eyes were cold, and she rushed out of the Song family’s mining area.

When it was dawn, the miners of the Song family also began a busy day of work.

A quarry master of the Song family walked into the mining area, bleary-eyed. But when he saw the situation in front of him, he let out a scream of horror.

“Oh no. Master, something bad happened.” The quarry master was so scared that he stumbled as he ran towards the Song manor.

When Song Wanshi and his son got the news, they rushed to the mining area with Master Lian.

Under the morning light, the Song family’s entire mining area had turned into a reddish hue.

All the ores, including the mine area that had not been excavated, rusted overnight.

That rust was not the common rust moss and was more like a rust disaster.

“Destroyed. It’s all destroyed! Master Lian, what on earth is going on?” Song Wanshi had a lump of anger in his throat, unable to push it up or down.

“This… I don’t understand it as well. There is no frozen grass nearby. What is the matter with these ores?” Even Master Lian’s eyes were opened wide. He had been training to be an alchemist for so many years, but he had never encountered dark iron ores having such serious rust.

“Master Lian, is there any other way to save this mining area?” Song Wanshi’s voice trembled.

“The ore and soil have been destroyed. There is no other way to save it even if we have a high-grade elemental fire.” It shocked Master Lian. The person who had done this was too vicious. He had destroyed the entire mining area.

Master Lian would not know about frozen grass that was ten years old, let alone about ice poison.

Because this kind of special ice poison was not accessible to ordinary alchemists.

Ice poison was a kind of poison that Ye Lingyue had learned from Poison Supremacy Jadehand.

The Hongmeng letter and Qian cauldron which Immortal Hongmeng left were all medical cases and methods to refine pills. Poison Supremacy Jadehand was different.

Poison Supremacy Jadehand left two things behind. Other than ‘Thirteen Needles of the Otherworld,’ there was another book called ‘Five Poisons Treasure Book.’ There were poisons of all kinds recorded in the book, and this ice poison was one of the water poisons.

Of course, these things were unimaginable to Master Lian or Song Wanshi.

Who would have guessed that such a vicious technique came from a 13-year-old girl?

“It must be Ye Gu that old b*stard. No, I’m going to see the Town Leader.” Song Wanshi’s heart ached. Someone destroyed his mine and it must have had something to do with the Ye family.

Song Wanshi could not stomach this insult. Taking Song Guangyi with him, he angrily went to look for Town Leader Liu.

Old Town Leader Liu had no choice but to summon the people from the Song and Ye family.

“What a joke! Whenever something happens to the Song family mine, you’ll accuse us of doing it. But if it was the other way around, who would we go to then?” Hearing this, Ye Gu was furious. There were cracks in the armrest of the boxwood chair that was under his hands.

“Hmph. If you didn’t do it, why would the mine turn into this? In a hundred years, no plants or trees could be grown there, let alone mine. It’s clear that you are burning our bridges down.” Song Wanshi was so angry that he insisted that Ye Gu was the one who ordered people to do it.

And Ye Gu was also insisting that the Song family was responsible for what had happened to the Ye family’s mine.

The two heads of the family were all red-faced as they quarreled and almost ended up in a brawl.

“Master Ye, Master Song, have you quarreled enough?” Old Town Leader Liu shouted with great dignity.

Ye Gu and Song Wanshi stopped their quarreling.

“The Seven Northern Hill mine is already under Ye family’s possession. As for Master Song, Seven Star Mountain is so big and there are many mines. If one mine is gone, there are still others. As compensation, those mines that have not yet been developed will be temporarily under the Song family, However, 40% of the ores you develop will be in the possession of Autumn Maple town.” Old Town Leader Liu was annoyed by the quarreling and with a wave of his hand, he decided the matter.

When Ye Gu heard this, he did not look so good, but Song Wanshi’s expression relaxed slightly.

“Also, I received the news that sometime later, the county will hold a smelting conference. The first place in the conference will probably become the supplier of dark iron for the Great Xia military,” Old Town Leader Liu said meaningfully.

Supplier of dark iron to the military? It was a lucrative opportunity!

If they could get involved with the military, it would mean that their position would rise. In the county city, even a small family could occupy a position there.

Ye Gu and Song Wanshi immediately understood this, and after thanking the town leader, they left respectfully.

Seeing that the heads of the Song and Ye family had gone, Old Town Leader still had a thoughtful expression on his face.

“Master, what are you going to do? Why did we let the Ye family take part in the smelting conference? Is it because of that little girl from the Ye family? The county city is not like Autumn Maple town. It’s the county city’s Alchemist Association lair. The Ye family may not be able to win the first place in the smelting conference.”

However, Master’s thoughts were not what servants like him could figure out. The Old Town Leader could not figure it out for a while, so he did not think about it anymore.
