only……

Lin realized in his later years what it said in words: "What do you mean by me following the plot?"

[Oh, I forgot to tell the host, this is actually the script I created for you, "The Road to the Demon Lord". You can get rewards as long as you follow the plot. ]

When Lin Late heard this, he developed a rebellious mentality: "What if I don't follow the plot?"

[If you don't follow the plot, there will be no reward.] The system said in a very human tone.

From its words, Lin Wannian realized that the system had really changed. He guessed the other party's intentions and continued to ask, "What is the source world?"

At the beginning, he asked about the origin of the system, and the other party said that he was not from the God Realm. Now his origin has been exposed, the source world? Is there another world besides theirs?

The system was brainless and directly exposed to Lin Wannian, [The source world is where our systems were born, and it is also the birthplace of many worlds. Host, you are a character in one of these worlds. ]

"Oh." When Lin Wannian heard its answer, he already had other plans in mind.

He came to his senses and continued to flip through the book in his hand.

Can the Xuanbing beast's stuff solve this gray fog? This is indeed a method worth exploring.

To verify this method.

When Lin returned to the inn to rest in his later years, after setting up the barrier, he took out the gray mist he had brought from the Snow Village. Under the white ball of spiritual power, the gray mist was jumping, trying to leave here.

Lin Wannian caught the Xuanbing Beast, which at this time still had a piece of ice crystal in its mouth. It did not expect that Lin Wannian would take it out at this time. It was startled at first, and then quickly swallowed the ice crystal in its mouth. Its round ears drooped down, and it looked at Lin Wannian timidly.

Lin watched it operate in his later years: "..."

After a moment of silence, he rubbed its head and pointed at the spirit ball on his palm: "Spray here."

“Gu——”

Seeing that he was not angry, the Xuanbing Beast pricked up its round ears and opened its mouth to exhale.

When the icy air blew over, Lin Wannian withdrew the spirit ball. The gray fog wanted to escape, but was instantly frozen by the icy air. Lin Wannian then generated a spirit ball from the outside to wrap it up, and then carefully observed its changes. Under the ice-blue gas, the thing's floating movements slowed down a lot.

"This gray bug is afraid of ice?"

He muttered to himself, and then said to the system: "System, since you are my system and helped me ascend to the position of Demon Lord, I am in trouble now. Shouldn't you lend me a hand? Wouldn't this speed up the plot progress?"

077 listened to his words and recalled that the previous host was not as talkative as the current one. As expected, once the memory is lost, the personality will change: [Sorry host, I don’t know either. The information I know now is the latest. What to do next is up to you to explore. ]

“…”

Lin Wannian had no choice but to continue the experiment. Under the repeated icy air, the gray fog stopped jumping. At this time, Yu Qi, who was meditating in another place, opened his eyes. There was a thoughtful look on his face. Not long ago, he realized that the power of a small part of the gray shadow insects he had thrown out was weakening.

Could it be that those people found a way to treat it?

Thinking of this, he raised his hand, and a group of more dense gray worms suddenly appeared in his palm. This was his latest product. The ones he released to Xuecun were just the initial version of the gray shadow worms.

"Where is the magic crystal?" he muttered to himself, then waved his hand and told the gray shadow bugs as small as floating dust: "Go find it."

Those tiny gray shadow insects understood his instructions and flew away, soon disappearing into the thick night.

The next day, when Lin Wannian came over, before he could say anything, Liu Ziqin stuffed a steelyard in his hand and said, "Take out your alchemy furnace, and weigh the medicine according to this recipe to make the elixir. How many pills can your alchemy furnace make at most?"

Lin Wannian glanced at the dosage of the medicinal materials on the prescription, then looked at the dark circles under Liu Ziqin's eyes: "I can practice three. Senior sister, have you heard of Tianhan Pill?"

"Tianhan Pill?" Liu Ziqin was stunned for a moment: "Why are you asking this?"

Lin Wannian smiled slightly: "It's like this, Tianhan Pill can wash away the impurities on the cultivator's body. It is different from Xisui Pill. It washes more thoroughly and can even wash away excess spiritual roots. The infected gray fog automatically invades the human body, so it can naturally be regarded as an external infection in the body and can be washed away more easily. I think we can study pills like Tianhan Pill, which will be easier than testing the medicine again and again."

When Shen Linglong heard this, she gave a thumbs up and said, "Fellow Daoist Lin, your idea is good, but the medicinal materials needed for the secret recipe of Tianhan Pill seem to be very difficult to obtain." As she spoke, she frowned.

"What Brother Lin said is good." Lu Ying walked over slowly.

"Master."

"Elder Lu."

Lu Ying walked up to them and said, "Although it is difficult to find the medicinal materials for Tianhan Pill, for the sake of these infected monks and the future, we must find these medicinal materials."

"Yes." The cultivator from the Hehuan Sect responded quickly.

Lu Ying looked at Lin Wannian, then at Liu Ziqin: "This time, it is all thanks to the help of your Xingyuan Sect."

Facing the gratitude from other sect elders, Liu Ziqin couldn't help but be modest: "It's okay, it's normal for sects to help each other."

With the ideas provided by Lin Wannian, they began to look for elixirs that could purify the body. However, collecting medicinal materials would take more time. Fortunately, the Hehuan Sect was wealthy and had a large manpower base. They could directly purchase medicinal materials with Lingjing. After finding the medicinal materials, they would select the most effective ones from the many medicinal materials for making elixirs as the final elixir.

As time passed, the living dead became more and more restless. Even though they were tied up and immobilized, their dantians were gradually being polluted, and the pressure on the medicine practitioners was increasing.

After the formation was confirmed to be correct, Yu Sang and the others hurried over to help Lin Wannian and the others, and carefully picked the herbs on the side. However, some cultivators seemed a little flustered because they were not familiar with the herbs.

Yu Sang was helping Lin Wannian on the side, chatting with him quietly: "I heard that it was you who proposed the Tianhan Pill. How did you come up with it?"

Lin’s answer in his later years was straightforward: “I just associate what I see with it.”

Yu Sang: “…That’s right.”

While weighing the medicine, Lin Late asked Yu Sang, "Do you still think this matter is related to the demon clan?"

Yu Sang said seriously, "Well, apart from the demons, I can't imagine who would do such a heartless thing."
