Under the old locust tree in Wuli in the west of the city, in fact, even if there is no old locust tree, Zhou Cheng can easily find Liu Hui's residence, because there is only such a thatched courtyard fenced with bamboo strips.

There was no courtyard gate in the small courtyard, and Zhou Cheng did not ask outside the courtyard, so he walked directly into it.

Zhou Cheng walked casually in the courtyard, looking at the various strange instruments placed messily under his feet.

These were all wooden instruments, and they looked mostly parts, except for one or two that were slightly larger, and looked a little bit like an armillary sphere, a geodynamic sphere, or something like that.

Zhou Cheng casually picked up a wooden round rail on the ground, and he found that there were many scales on it, and there were some circular relief patterns, like stars.

After taking a closer look, Zhou Cheng didn't know why, so he put down the wooden rail and walked towards the thatched hut.

Walking into the house, there were messy papers everywhere, and Liu Hui was not seen in the house.

didn't see the master, Zhou Cheng didn't leave immediately, but walked in the house casually, he walked a few steps and picked up a piece of paper on the ground, but the strange patterns composed of numbers and lines on it, Zhou Cheng still couldn't understand what it meant.

picked up several in a row, all of them were the same, but Zhou Cheng didn't understand the meaning of any of them.

Then Zhou Cheng looked at the four walls again, the walls were still covered with paper, and the paper was still covered with those strange numbers and patterns, and finally Zhou Cheng's eyes fell on a somewhat unusual piece of paper.

Slowly approaching the wall, Zhou Cheng found that this piece of paper was the only one he could understand, because there were only a few names written on it, and four of them had made outstanding contributions in the field of astronomy and could be called the names of the sages of a generation of grandmasters.

Gande, Shi Shen, Luo Xiahong, Zhang Heng, Zhou Cheng has more or less heard of the names of these four people.

Zhou Cheng had a mask on his face, and he couldn't see his expression at the moment, but his eyes still showed a look of doubt.

Suddenly, Zhou Cheng turned his head to look outside the house, and in his perception, the crazy old man Liu Hui had already walked into the courtyard and was walking towards the house.

"Huh, it turned out to be you....." Liu Hui was holding a wine jar in his hand, and when he saw Zhou Cheng, he was a little surprised at first, and then a little delighted.

Liu Hui's expression was without reproach, and it seemed that there was nothing wrong with Zhou Cheng appearing in his house.

"Mr. Liu, is this coming back from buying wine?" Zhou Cheng looked at the wine jar in Liu Hui's hand, and said with a bit of playfulness in his voice.

Liu Hui carried the wine jar and walked to the only desk in the house, he swept a few ancient books on the table, pushed all of them to the ground, and then put the wine jar heavily on the desk.

After doing all this, Liu Hui said an inexplicable sentence: "I have never drunk alcohol in my life, so I naturally want to taste it before I die!"

"Mr. Liu's age..... If you say that you have never drunk alcohol in your life, it is unbelievable!" Zhou Cheng didn't believe Liu Hui's words.

From the first time he met Liu Hui, every sentence that this crazy old man said was unbelievable, if it weren't for Zhou Cheng's lingering words when he was in retreat, Zhou Cheng would definitely think that Liu Hui was a madman.

"Drinking and making a mistake... I can't afford to waste my time on other things that don't matter. Liu Hui said casually, his hand had already slapped open the wine jar, and the fragrance of wine instantly spread.

Zhou Cheng shook his head helplessly, Liu Hui's words were simply not believable.

In Zhou Cheng's eyes, he felt that Liu Hui was a crazy old man who behaved strangely and was a little arrogant.

"Ahem.... Bah.... Why is it so unpleasant? It smells so good, why does it smell so good?" Liu Hui had already raised his head and took a sip, but then he coughed twice, and then vomited it all.

Looking at Liu Hui's appearance, Zhou Cheng was a little convinced that this crazy old man should have really never drunk alcohol.

"Mr. Liu said that day, the stars we see are all fake, I don't know what is going on? This question has been bothering me recently, but I can't figure it out!" Zhou Cheng directly explained his intentions.

"The old man doesn't have time to explain to you, I've compiled a book of notes in the past few days, if you're interested, take it. There are also old books here, you can take them if you like. Liu Hui took out a booklet from his arms and threw it directly in front of Zhou Cheng, and then pointed to the books that he had just pushed to the ground.

"Sir wants to travel far away?" Zhou Cheng asked with some puzzlement.

Zhou Cheng could feel that Liu Hui was dying soon, and maybe even in the next day or two, so when Liu Hui said that he was going to die just now, Zhou Cheng didn't feel strange.

"It's a long journey, isn't it..... Is it a long journey after death?" Liu Hui said as he took off the wooden hairpin on his head and combed his somewhat messy hair again.

Zhou Cheng felt that he couldn't communicate with this crazy old man at all, and what the two said was not on the same road at all. Zhou Cheng didn't know how to answer, and Liu Hui said to himself:

"Alas..... After living for a lifetime, you should still be decent when you die, but this dress is a little shabby!"

Hearing Liu Hui's words to himself, Zhou Cheng realized that he was taking care of his hair just to make himself more decent when he died.

What a crazy old man.....

Liu Hui ignored Zhou Cheng, and after finishing his hair, he pulled on his clothes and straightened the placket.

"It's better now, isn't it?"

Liu Hui didn't even have a bronze mirror at home, so at this moment he directly regarded Zhou Cheng as a mirror and asked if his appearance was appropriate.

Zhou Cheng looked at the crazy old man a little speechlessly, and nodded helplessly.

The old man's crazy and stupid appearance made Zhou Cheng feel a little inexplicably cute.

When a person faces his own death, he can be so calm, or so heartless.

"Alright..... It's time for the old man to go..... What a reluctance!" Suddenly, Liu Hui's expression was solemn, he raised his eyes to look at his residence, and finally his gaze fell on the paper with the names of the four sages written on it.

Zhou Cheng's eyes stared at Liu Hui, and he felt that a mysterious and strange aura suddenly appeared on Liu Hui's body.

Under Zhou Cheng's gaze, Liu Hui's expression suddenly became extremely serious, and his eyes were full of wisdom, not at all like the crazy appearance before.

Liu Hui at this moment, anyone who sees it is a great Confucian sage!

"The old man has been looking for the way all his life, and he has finally peeked into the way, and the unfinished things in this life will take the road of the sages in the next life....." Liu Hui's tone was completely like a different person, and the momentum on his body was constantly improving.

Zhou Cheng was shocked to find that Liu Hui, who was already dying, soon surpassed ordinary people in his body, and even began to have the aura of entering the Dao.

However, just when Zhou Cheng was shocked beyond measure, an even greater shock appeared.

Liu Hui's eyes were fierce, and countless lines appeared in those eyes, and these intertwined lines seemed to be intertwined with warp and weft, forming a mysterious figure.

"Mind.... Guarding the Spirit...."Liu Hui's mouth sounded an ethereal and distant voice, as if these simple words had traveled through endless time and space, from the distant primeval era.

"This ..... Dao Yun...."Zhou Cheng suddenly tensed, he saw that the mysterious graphics in Liu Hui's eyes were extremely similar to the so-called Dao Yun demonstrated by Dongfang Ling many years ago.

"Lung God..... Void Cheng...."Liu Hui's voice that seemed to come from Taigu continued to sound.

And as Liu Hui continued to say a word, his thin and decaying body burst out with a power that made the soul tremble.

"Liver God..... Hanming...."

"Kidney God..... Baby-rearing...."

"Spleen and spirit..... Soul Stop...."

"Courage God..... prestige...."

Liu Hui opened his mouth six times in a row, and when he finished saying these six sentences, a heavy coercion suddenly appeared in the entire thatched house, although it was formless and substantial, but it made Zhou Cheng almost out of breath, and all the books and papers in the room were windless and automatic, wafting and rattling in the room.

"Impossible..... This is the Taoist Yuan Shen..... Instantly enter the Tao, and become a god in a moment..... Who are you?" Zhou Cheng Qingping's sword pill moved, the sword light shrouded his body, and he suddenly got up under the heavy pressure.

On Liu Hui's old body, a humanoid light and shadow slowly stood up, and the light and shadow were exactly the same as Liu Hui's appearance, which was the Taoist spirit that countless cultivators dreamed of.

"The old man is just a seeker who wants nothing else..... Believe me, the stars above your head are all fake....." Liu Hui's Yuan Shen glanced at Zhou Cheng, and then the Yuan Shen looked at the void in front of him.

Zhou Cheng no longer doubted Liu Hui's words, a character who could enter the Tao in an instant and achieve Taoism in a moment, there was no reason to be crazy to deceive himself.

As Liu Hui Yuan Shen faced a little in front of him, a dark and deep whirlpool appeared, and as soon as this whirlpool appeared, it exuded a corrupt and gloomy aura.

Although he didn't know what was inside the whirlpool, Zhou Cheng subconsciously thought of a word that everyone knew.

"Netherworld"

At this moment, Zhou Cheng also completely understood that Liu Hui's seemingly crazy words before were actually the reincarnation of the Yuan Shen.

As soon as the whirlpool appeared in front of him, Liu Hui Yuanshen plunged into it without hesitation.

As Liu Hui's Yuan Shen disappeared, the aura of the Netherworld Mansion quickly dissipated, and the dark and deep vortex finally shrank and condensed into a black dot, and then disappeared completely.

In the blink of an eye, the paper in the thatched hut fell, and everything was calm, but Liu Hui's body was still sitting in front of the desk, his head hanging heavily, and there was no trace of vitality.
