In the next few days, Xia Fan spent all his time refining and improving the elixir.

The pills prepared for Ye Yi had all been refined on the first day, so in the process of refining the pills, Ye Ye had been cultivating in his bedroom to digest the violent vitality that he had absorbed into his body when he was training in the Fierce Beast Wasteland.

As Ye still began to cultivate, the little guy finally regained his beast body freedom.

So when Xia Fan was refining the elixir, the little guy would squat on the side, and his two bright eyes were full of curiosity to watch Xia Fan's every move.

From time to time, he would stick his nose out and sniff at those pills, and occasionally even eat one of the pills directly into his stomach.

For this kind of action of the little guy, Xia Fan will never stop it.

Because these pills themselves will not do any harm to the little guy's body, and the little guy himself has a strong instinct to perceive danger, so if the pill is not beneficial to it, it will never take the initiative to take it.

What really made Xia Fan pay attention was that the little guy seemed to have passed the weak state of the nascent stage, and after coming to Kyoto Prefecture, the little guy's need for sleep was far less than before, and the time to fall asleep every day was greatly reduced, basically no different from the sleep time that normal people need in a day.

After several days of hard work, Xia Fan finally finished refining and optimizing all the pills.

For this reason, about one-tenth of the rare medicinal materials stored in the ring were consumed.

After spending about half a day writing down how these drugs should be used, when to use them, and some other things that needed to be explained, Xia Fan took out the Ethereal Spirit Ring, and then stuffed all the pills and the paper with the contents in it.

At the same time, he called the shopkeeper in the inn who welcomed them in on the first day, threw a few ingots of silver to the shopkeeper, and asked the shopkeeper to go to the neighborhood to buy some Kyoto Prefecture specialties.

It wasn't until all these things were ready that Xia Fan mixed the Ethereal Ring into those specialties and wrote a letter similar to a letter from home.

The contents of the letters seemed to be just gossip that didn't make any sense.

But if you read it in a specific skipping order, you will see another paragraph that Xia Fan really wants to convey.

The content naturally has to do with the usage of the Ethereal Ring and what is inside.

This is a very simple password that Xia Fan had made with his father Xia Ya before leaving Qingyang City.

In the entire Xia family, only he and Xia Ya knew how to decipher this code.

Although it is simple, it is impossible for people who do not know the problem to notice the problem, because the order of the words is completely irregular, and only those who make the password and know the password can see the real meaning of it.

Just like locks, the more primitive the lock, the less likely it is to be brute-forced.

Of course, Xia Fan also learned this practice from the black hand organization.

Everything was ready, Xia Fan said hello to Ye Yi in the bedroom, leaving Ye still to calm down the vitality in his body that was no longer so restless, and then put the little guy on his shoulder, carrying the big bag of specialties, and walked out of the guest room.

As the spring exams for Kyoto's three major colleges approached, a large number of young people who were confident in themselves had already arrived in Kyoto Prefecture ahead of schedule.

Compared to the 'War Academy' and the 'Kyoto Imperial Academy', the number of young people who want to be admitted to the 'Jimbu Academy' is undoubtedly the largest.

Therefore, 'Kyoto Yipin', an inn located opposite the gate of Shenwu Academy, naturally started business.

When Xia Fan walked to the first floor of the inn with his things, there happened to be two young people who came from other places standing in front of the counter on the first floor of the inn, arguing with the shopkeeper behind the counter with some excitement.

The content of the argument was nothing more than the shopkeeper saying that there were no more empty rooms, but the two young men from other places seemed to be quite pampered when they were at home, and they insisted on asking the shopkeeper to find a way to make room for them.

This kind of thing happens every year, so the shopkeeper is just dealing with it routinely, and Xia Fan doesn't pay too much attention to it.

Coming out of the inn, according to the vague memory in his mind, Xia Fan didn't spend much effort to find the nearest post post nearby.

After stepping in, Xia Fan wrote down the things he wanted to mail and the address he wanted to mail in detail, paid an extremely high fee, completed all the procedures, and then walked out of the post post.

The postal routes within the territory of the Daqian Dynasty were quite developed, because they were in the land of a hundred battles, the border areas of the Daqian Dynasty were constantly fighting all the year round, in order to improve the speed of information transmission as much as possible, so for the construction of postal routes, the Daqian Dynasty has been making great efforts for hundreds of years.

Originally, at the beginning, this kind of post was specially used by the military, and when the war was most urgent, there would even be strong people above the level of the martial king, who were temporarily recruited as messengers.

However, with the rapid development of the construction of postal routes, it is no longer enough to give full play to the efficiency of postal routes just for the use of the military.

So gradually there were government departments that joined the use of the postal route to issue decrees and other things.

In recent decades, the national strength of the Daqian Dynasty has developed to an extremely prosperous situation, which is enough to form a huge deterrent to several surrounding countries.

As a result, the pressure on the frontier began to gradually become relaxed, far less than the incessant war that raged in the sky and lasted for many years as it had decades ago.

As a result, the huge postal network will inevitably lead to a partial waste of resources.

Under these circumstances, in order to ensure that the postal route would not be hidden from this and to make up for part of the military expenditure, the postal route, which was originally only official, began to be open to the people.

There are many advantages, such as absolute security, such as absolute speed, such as since it was partially opened to the public, there has never been a single mail failure or mail error.

Relatively speaking, there is only one disadvantage, that is, it is too expensive.

However, this kind of expense is still within Xia Fan's affordability, although when paying the fee, even with Xia Fan's current net worth, he will inevitably feel a trace of pain.

Coming out of the post office, Xia Fan had no intention of wandering around, although Kyoto was prosperous, but for Xia Fan, the attraction was not too big.

When a person's state of mind is already like that of a middle-aged person who has gone through vicissitudes, it is difficult to expect him to be full of curiosity and inquisitive thoughts about everything like a teenager.

People always mature with more experiences, but they also lose many of their simple pleasures as they mature.

In stark contrast to Xia Fan's lack of interest, it was the little guy lying on his shoulder, staring at his round eyes all the way, constantly turning his little head, and looking at everything along the way excitedly.

From time to time, because he saw something that he couldn't understand, he kept waving his little paws to scratch Xia Fan's hair.

Xia Fan walked slowly all the way, gently messing with the little guy all the way, and returned to the inn.

However, what he didn't expect was that as soon as he stepped into the door of the inn, he heard a girl's exclamation.

Immediately after a gust of incense blew, a girl dressed in red rushed directly in front of him!

It's just that the girl's eyes didn't fall on him at all, but stared at the little guy on his shoulder......
