Du Kang poured himself a glass of wine and spoke eloquently.

There are two kinds of wine he makes, one is low-alcohol ambergris and the other is high-strength ambergris. As the name suggests, the difference between the two liquors is that the content of ambergris is different.

Low-alcohol ambergris wine, that is, ordinary Du Kang wine, has a strong taste, has the effect of invigorating blood and strengthening the body, dispelling diseases and prolonging life. What Du Xiaobai drank on the boat, and what Du Kang asked a few people to bring back to Lingdie Fort from Granny Meng, was this low-alcohol ambergris.

The high-degree ambergris wine has a more refined and fiery taste, and the effect of prolonging life is not comparable to ordinary low-alcohol ambergris. Of course, the quantity of this highly refined ambergris is very small.

Ambergris wine was made by Du Kang during the reign of Xia Yu, the last generation of Tang Po, and the core material used was extracted from Xia Po's pet dragon, and the amount of wine made at that time was very large. Later, Granny Xia handed over her position to Meng Yiyi and disappeared with her pet dragon. Ambergris has become a swan song, only decreasing, not increasing.

Although ambergris only decreases but does not increase, there are actually very few people who have drunk it, so relatively speaking, the reduction should be very limited.

Especially in the early stage of production, the use of ambergris was strictly controlled by Xia Yu, and even the brewer Du Kang himself could only enjoy the right to use ambergris, not the right to distribute ambergris. To put it simply, you can drink it yourself, but you can't give it away.

Moreover, when Xia Yu left, he also formulated extremely strict rules for the use of ambergris - he has extremely scarce abilities and has extremely high virtues at the same time, and the combination of the two is the minimum entry threshold for drinking ambergris. And even after entering the threshold, you have to go through Xia Yu's strict assessment before you can taste ambergris and increase your lifespan.

Therefore, in the Xia Yu period, people who were lucky enough to drink ambergris wine were really rare, and even if the head of the underworld changed from generation to generation, it was not blessed.

Xia Yu's reason for formulating such a rule is that ambergris itself has the effect of prolonging life, and this function affects the balance of the world too much, and people's hearts are unpredictable, and no one can guarantee what a person who looks virtuous on the outside has a long lifespan. After the length of life is extended, many things will become uncherished and not cared about. At that time, the choice between good and evil in the human heart will no longer have the most effective self-restraint.

To put it simply, once people don't have to worry about death, the heart of desire will swell unscrupulously and start doing evil, so it must be controlled.

Before Meng Yiyi took over Tang Po, as far as Du Kang himself knew, there were only four people who had drunk high ambergris: the second generation of Tang Po Xia Yu himself, the winemaker Du Kang himself, the Five Elements Prophet Gu Zigui, and the hell prison officer Kang Sihai.

As for whether Xia Yu gave it to others to drink, Du Kang didn't know, after all, he didn't stay by Xia Yu's side all the time.

After Meng Yiyi took over as Tompo, he received many rules and prohibitions at the same time. One of them is to strictly abide by the regulations on the use of ambergris and must not be abused.

Thousands of years have passed, and Meng Yiyi has always firmly abided by Xia Yu's rules, never crossed the thunder pool, and never let anyone drink high ambergris again. Except for herself and Du Kang.

Meng Yiyi drank it himself, in order to continue the duties of Tong Po. Another rule she received from Xia Yu was that she could use ambergris to prolong her life until a suitable successor was found.

However, Meng Yiyi never found a more suitable person to succeed Tang Po. This matter, which has never been resolved, has become a worry that has always haunted Meng Yiyi's heart.

However, since Meng Yiyi has never had a successor, she can only use ambergris frequently to prolong her life. After a long time, Meng Yiyi discovered something that Xia Yu had not discovered, that is, as time went by, she needed to drink more and more ambergris every time. This has also led to a constant decrease in the high levels of ambergris.

Everything in the world has two sides, and the truth is that everything must be the opposite. Ambergris is good, but if you drink too much, your body will also suffer a certain degree of damage. Over time, there must be irreversible damage.

After Du Kang found out that Meng Yiyi was sick, Du Kang suspected that Meng Yiyi's illness might be related to the excessive use of high ambergris, but there was no way to test it, so he could only ask Xiao Yuyao to come and do a test without Meng Yiyi noticing.

This matter can only be done by asking Xiao Yuyao to do it. Not only because Xiao Yuyao is a trustworthy person, but also because the matter of ambergris cannot be spread outside, otherwise, if someone targets ambergris wine that can prolong life, then Meng Yiyi will definitely become the target of many people.

After Xiao Yuyao listened to the story of ambergris, her heart couldn't calm down for a long time. She then understood why Granny Meng was always so greedy for alcohol, she used to only think that her mother-in-law liked to drink, but now she realized that it was her mother-in-law who needed to drink. Perhaps, her amnesia also has something to do with her heavy drinking.

Xiao Yuyao had an inexplicable sense of foreboding, and after Du Kang went back to the house to sleep, she lay on Granny Meng's bed, tossing and turning, until the sky was white, and then fell asleep.

......

......

In the western Pacific Sea, about two hundred nautical miles from the Netherworld, there is an inconspicuous island. The island is very small, less than a kilometer long and wide. However, the island is also densely wooded, and the birds come and go, mixed with the sound of the waves around it, giving people a very comfortable feeling.

In the middle of the island, there is a very dense jungle of trees. Hidden among the jungles is a small, dilapidated stone house that would have been abandoned and uninhabited if you didn't look closely.

In the small stone house, Meng Yiyi sat obediently on a wooden bed, holding a cup of freshly boiled hot water in his hand, quietly looking at the old woman opposite who was cooking with firewood.

The old woman's back could no longer be straightened, so she hunched her back and forth, but there was no trace of complexity in the movements, and if you did not look at the wrinkled skin on her face, it made people think that this was just a young woman with a disease in the lumbar spine.

"You've worked hard all these years. ”

The old woman turned her back to Meng Yiyi, cut the vegetables in her hand, and said without looking back.

Meng Yiyi smiled faintly and replied: "Compared to what my sister did, my sister is not bitter at all. ”

The old woman didn't stop what she was doing, as if she hadn't heard Meng Yiyi's praise at all, "Find an heir early, it's boring to live too long." ”

Meng Yiyi gently stroked the bottom of the cup with his hand and replied gently, "Eh." ”

Outside the small stone house, nearly twenty kilometers above it, from a distance, there was a faint trace of a crack with a strange color, and next to the crack, a flying dragon was flipping and circling, spraying water into the crack from time to time. If Old Man Du Kang is here, he will definitely be overjoyed, because this flying dragon is the pet dragon of his old friend, Granny Xia Yu.
