Li Yu bent down and carefully observed the elixir in front of him.

The elixir is about ten centimeters tall, red all over, with brown spots, like rust.

Each spiritual medicine only has three sword-shaped leaves, and it feels like it is vaguely split when you reach out and touch it.

"This is...Iron Sword Grass!"

A flash of inspiration in Li Yu's mind, and then he threw out an appraisal confirmation.

Name: Iron Sword Grass

Type: Spiritual Medicine

Grade: Nine-grade

Function: Detoxify, avoid evil...

Introduction: This is an ordinary spiritual medicine that grows in a place with strong evil spirits.

"It's really interesting to grow in the evil place but it has the effect of avoiding evil."

Li Yu showed a smile on his face and then stood up.

"Master, are these spiritual medicines?"

Xuan Hua came to Li Yu and asked curiously.

"Um."

Li Yu nodded and smiled, "This kind of spiritual medicine is called Iron Sword Grass. Xuanhua has made great contributions!"

Li Yu has also seen many ninth-grade spiritual medicines. Although he is excited, he is still fine.

What really made him happy was that the adaptation of the environment here was a good place to plant iron sword grass.

In the future, as long as someone is sent to take care of it, he will have a steady supply of iron sword grass.

"The last general dares not take credit, these are the duties that the last general should do."

Xuan Hua's face was humble and did not have the joy of making contributions.

"If you have merit, you have merit. You don't have to worry about jealousy or something."

Li Yu glanced at the other party and shook his head and said, "If you find someone deliberately suppressing you in the future, you can go to the county government to find Song Yuan, or come to the Li government to find me."

"Thank you, Lord, to understand, I will understand."

Xuan Hua bowed again. With Li Yu's words, he did not lose money when he saw his treasure this time.

While the two were talking, there was no movement in the distance, and it was obvious that the battle had ended.

Sure enough, Yin Wujiu dragged the centipede spirit several times larger than himself and returned.

boom!

Yin Wujiu threw the centipede spirit on the ground, splashing a burst of sand.

Then he came to Li Yu a few steps and bowed: "Master, I am fortunate to be unfair to my fate, and I have killed this demon!"

Li Yu did not look at the corpse on the ground, but walked quickly to Yin Wujiu, helped him up, and cared for him.

"Wujiu is very powerful and easily killing this monster is like a ghost and god reincarnation. I wonder if you are injured? I happen to know some medical skills and pills."

Yin Wujiu stood up and shook his head and said, "Don't worry, Lord, the last general is the body of a ghost. This monster can't hurt me if it is an idle attack. A battle is just a lot of energy, and other minor injuries are not enough."

As he said that, he patted his chest, and apart from his already broken armor, he really couldn't tell where he was injured.

Li Yu heard this, but he did not agree, "The injury is not big or small. Sometimes, some minor injuries accumulate and they will eventually lead to big problems."

"It just so happens that there is a thousand-year-old tree heart in my mansion. After I practice the pill, I will send it to you."

Seeing that Li Yu cared about him so much, Yin Wujiu agreed to refuse.

The Jinyiwei left behind the body to deal with the centipede spirit, while Li Yu proposed to go to the cave to take a look.

Among the humans and ghosts present, Li Yu was the main one, and the centipede monster died, and there was no threat.

Of course, no one doesn't open his eyes and jump out to stop him.

When Li Yu entered the cave, in addition to the black fog transformed by the Yinsha, he also emitted a foul stench.

The soldiers of Tiance held up a torch to illuminate everyone. Tieshan activated his blood to drive away the dark fog in the cave.

After some operation, everyone saw clearly the scene inside the cave.

At the same time, they also discovered the source of the stench.

In the cave, there are many bones and unfinished corpses remaining on the ground.

Judging from the remaining corpses and bones, these are all the bones of wild animals and there is no human race.

Under the escort of everyone, Li Yu continued to go deeper and finally came to a huge cave hall, and then saw a big pit in the center.

"This hole should be left by the centipede spirit."

Yin Wujiu stared at the entrance of the cave and suddenly spoke.

"Centipedes usually live in dark and humid places. The environment in the ancient battlefield is obviously not suitable, so it makes sense to live underground by digging holes."

Li Yu nodded slightly, then saw something, quickly stepped forward, and picked up a red stone from the edge of the pit.

He pinched it with his hand and the stone was not broken. As he increased his strength, the latter had cracks and finally shattered.

"This is the Lingjin Mine!"

Li Yu's eyes lit up and he quickly made an appraisal.

Name: Chisha Iron

Type: Spiritual Gold

Grade: Nine-grade

Function: hard, rushing to the god...

Introduction: This is an ordinary spiritual gold that was born and strong in the place of military evil.

"It's indeed spiritual gold! Or red evil iron!"

Li Yu was excited. Among the materials for creating war soldiers, Chisha Iron is one of the main materials.

"No, I can't be happy too early. What if there are only a little bit of scattered here and no veins."

He forced himself to calm down, and he had discovered materials for building war soldiers before.

But it was all scattered, and no ore veins were found at all.

"Wujiu, Xuanhua, go down and continue digging the hole to see if there are any such ore!"

Li Yu immediately called Yin Wujiu and Xuanhua. Apart from him, there were two Yin generals who were the strongest, and they were the body of the ghost that was most suitable for exploring the underground.

"yes!"

Seeing that Li Yu was serious, Yin Wujiu and Xuan Hua immediately went down to the cave to investigate without saying a word.

After a moment, the two ghosts returned and brought out many red evil ores at the same time.

"Master, we dug a place below, full of such ores!"

Yin Wujiu reported the following situation.

"Haha! OK!"

Li Yu laughed loudly when he heard this, and explained the reason with the incomprehensible ghosts from the other side.

A mineral vein was found here, and Li Yu had no idea of ​​continuing to leave.

He needed to return to Wuling quickly, send people to investigate the length and depth of the ore veins, and formulate plans for mining.

Before leaving, he instructed Yin Wujiu and Xuanhua to protect the spiritual medicine and mineral veins.

Li Yu got on the carriage and rushed back to Wuling.

Instead of returning to Li's mansion, he went directly to the county mansion and found Song Yuan to share the good news, he also ordered him to find professionals to explore the mine veins immediately.

In the next few days, Li Yu focused on the mine veins.

On the day Yue Feng left, he went out of the city to see off his farewell himself.

This chapter is not over, please click on the next page to continue reading! During other times, you will run between the county government and the ancient battlefield.

It was not until the people below determined that the Chisha iron ore vein underground in the ancient battlefield was more than fifty miles long and five miles deep, and it was a medium-sized ore vein that he felt relieved.

When the mineral veins were discovered outside Wuling City, the county government also focused on mining.

Because the cave where the mineral veins were discovered at the beginning was next to the place where the Iron Sword Grass was produced, and the ancient battlefield was not suitable for mortals to stay for a long time.

Therefore, another location was chosen for the mining site of Chisha Iron Mine.

The mining veins are in full swing, and the site selection of the college for practicing the Four Arts has been completed and construction has begun.

At the same time, "Records of the Views of Demons, Ghosts, Ghosts, and Monsters" and "The True Interpretation of Martial Arts" were also spread under the influence of the county government.

Wuling and Yuanling counties, anyone who received these two books was grateful to the county government and Li Yu.
