Zhang Heng also comes to check on him from time to time.

One day, he brought an alchemy furnace, threw the carp into it, and spit out the yin fire to make the elixir.

Lu Shanguan asked: "Brother, you let me fish for the purpose of refining elixirs?"

Zhang Heng nodded: "Well, using Styx carp as the main medicine and adding Sanshengcao, you can refine the 'Sanshengdan'; if you add the Biangan flower, you can refine the 'Biangandan'."

"Brother, where are the Sanshengcao and Bianhuahua?"

"Master has a spiritual medicine garden on the top of Yinshan Mountain, where these two kinds of fairy grass are planted."

"Brother, I would like some seeds of fairy grass, is that okay?"

"You can, but it's difficult to grow them alive. Their growth conditions are very harsh. They need 'Netherworld', 'Netherworld' water, and 'Yin Gathering Spirit Array'."

"What is Hades?"

"Netherworld is the fairy soil extracted from the mud of the Styx River; Mingshui is the fairy water extracted from the water of the Styx River; both of these two kinds of fairy materials can be refined bit by bit by running the 'Twenty-Four Techniques of the Yin Fu of this Classic'

.As for the Yin Gathering Spirit Array, I have a jade slip and would like to trade it with you for a large ceramic urn."

"Thank you, senior brother. This big ceramic urn is a bit small. I'll help you find a bigger one later."

Some time later, Lu Shanguan gave a large urn ten miles in diameter to the Ghost Emperor Zhang Heng.

Zhang Heng took him to Guiguzi's medicinal garden, picked some seeds of Sanshengcao and Bianhua, and then taught him "The Twenty-Four Techniques of Yin Fu in this Classic".

Lu Shangguan collected the water and silt of the Styx River, and practiced the "Twenty-Four Techniques of the Yin Fu of this Classic" every day. While running the spells, he slowly extracted the earth and water of the underworld.

In addition, Dong Xiaowan also saw someone selling Netherland and Netherworld Water in Heizao Village at the foot of Yinshan Mountain. Although the Netherworld Earth and Netherworld Water were not pure enough, it was easier than refining them from the Styx River water.

Therefore, Lu Shanguan would buy half-finished Netherland and Netherworld Water every once in a while.

He handed these things to Lu Qianying, who sent them back to Shenjian Villa, and then sent them to Yuxu Peak from Shenjian Villa.

Lu Xiuzhu and Shen Qing'an, who presided over the Spiritual Soil Research Institute, obtained the Netherland and started researching it. They further purified the semi-finished Netherland with the help of the Netherworld Ghost Talisman mastered by the Lu family.

The Mingshui was sent to the Lingshui Research Institute and handed over to Lu Guze for purification.

The seeds of Sanshengcao and Bianhuahua were given to botanist Lu Lingchen.

In addition, there are two "Three Life Pills" and "The Other Shore Pill", which were handed over to the elixir masters Lu Xuge and Qiu Yingxue for analysis and research.

In turn, some information and techniques were also transmitted from Yuxu Peak to the underworld. Lu Shangguan and Dong Xiaowan obtained the ghost cultivation method provided by Zhao Gongming and the newly cracked Netherworld Ghost Talisman by the Lu family.

At this time, the Lu family already had 1,800 immortals and numerous scientific researchers.

The hundreds of thousands of people in the Lu family alone are not enough. Everyone adds fuel to the fire. In addition to the people with the blood of the Lu family, there are tens of millions of people hiding in Weiyang Palace, including some scientific researchers who accept the national level

Recruitment to provide technical support for cracking the basic theory of cultivation.

Although it has gone through a catastrophe, until this time, the Chinese Empire has not disintegrated. It still has the presbytery system, the Academy of Sciences still retains, and some famous universities continue to recruit students. However, some of the topics funded every year are from

Research on the transformation of scientific and technological civilization into cultivation theory.

Therefore, it can be said that the Lu family is not an isolated family, but a representative of the Chinese nation's perseverance and hard work in overcoming obstacles.
