Quartet City.

After more than half a month, Mo Chengjun's injury finally healed, and he was able to walk on the ground normally and do some less strenuous exercises.

There is a saying that 'it takes 100 days to break his muscles and bones', and his serious internal and external injuries were almost recovered in only 30 days, which made him more convinced of Lao Zhangtou's medical skills.

In the chat, he also learned that Lao Zhangtou looked quite old, but in fact, it was real, very old.

Now he is ninety years old, he still has no back pain, his legs are not sore, he walks in a hurry, although his hair is gray, but he does not see any age spots, his spirit is also vigorous, and his memory is particularly good.

In this state, it would be easy for you to say that he would live another twenty or thirty years.

And this made Mo Chengjun a little unbelievable.

You must know that even in his era, medical conditions were extremely developed, and the average age of human beings was only seventy.

If you look at the history and the present of mankind, the highest life expectancy that has been clearly recorded is only 130 years old.

And in this obviously ancient Xianxia world, the longevity of the human race has been greatly extended.

It was also under Mo Chengjun's intentional temptation that Old Man Zhang did not hide it, and went back and forth several times, which allowed him to have a clearer understanding.

In this world, you can't look at what the average life expectancy is, that's not accurate.

Because, there are so many dangers and accidental deaths here.

Although the Great Xuan Dynasty claims to dominate Kyushu, there has never been real peace on the border of the four directions, not to mention that there are all kinds of demons and monsters in the territory.

Sometimes just the aftermath of a battle can cause hundreds of mortals to be destroyed and killed.

In this world, if you want to observe the longevity of the human race, you have to look at those who live long.

It's just ordinary people, if there is no disease or disaster, good food and drink, it is actually normal to live to eighty.

It is also common for people who know how to maintain health such as doctors and scholars to live more than 100 years old, and those who live long can even reach 120 years old.

And in Old Man Zhang's words, as long as those immortal masters can complete the foundation building, the human body can be restored to the best state, and they can enjoy a lifespan of one hundred and fifty years.

This is also the maximum longevity of ordinary people.

Of course, this refers to the ordinary human race, those martial arts masters, and immortal masters are not among them, as for the longevity geometry?

Old man Zhang said that he didn't know very well!

Immortality, this may be the eternal obsession of human beings, knowing this, Mo Chengjun is more interested in this world, and he is even looking forward to the arrival of that female sword cultivator.

Unlike the rapid recovery of his body, Mo Chengjun's text learning is not ideal.

On the one hand, he always has to be a little obscured in front of others, and it is impossible to blatantly steal from school.

He's an immortal!

This identity has long been known and respected in the Xue family, but if the immortal master actually doesn't understand the Lingwen Seal Book, it would be a joke to say it.

The main thing is that it's not good if the identity arouses suspicion among others.

In order to study better, he also helped Mr. Xue of the Xue family's private school to suppress his cheap godson Xue Ling.

This little guy is naughty and mischievous, but he is not a master who loves to learn, let alone a person who saves face for the private school teacher, and it is common to play tricks wantonly.

But with Mo Chengjun here, it's different.

With him pressing, the little kid had to sit honestly and read seriously.

And this actually made Mo Chengjun gain the gratitude of the private school teacher.

On the other hand, Lingwen Seal Script is indeed somewhat complicated, and even has diametrically opposite meanings in different contexts.

And he, with the memory of the past, always likes to bring in when writing, which is written with either more strokes or less strokes, and what is written is not like four.

This made Mo Chengjun a little distressed, but this distress could only be overcome by him slowly.

And with the recovery of his body, Mo Chengjun couldn't stay.

After making sure that there was no major problem, he walked out of the Xue Mansion, led the two family members, and walked around the Sifang City.

He likes to listen to books in the teahouse, serve a cup of tea, watch the storyteller and the shocking wood, talk about the ancient and modern north and south, the rivers and lakes of the court, the general trend of the world, there is always a kind of 'not out of the house, but know the world's pride'.

He also likes to go to the restaurant to listen to music, the kind of Beijing drama that is about to disappear in his time, and he has experienced a different taste with Baizhuan back to the intestines.

Of course, he prefers to listen to those high-rollers boasting about themselves, and you can believe the content of it, but the stories of the characters that are accidentally revealed are what he cares about the most.

He prefers to wander the bustling streets, watching the merchants bring out all kinds of goods, or shouting or bargaining, which has a unique market atmosphere.

And his favorite snacks and delicacies are all kinds of snacks and delicacies, which seem to be less exquisite and rich than the world once was, but the taste is not bad.

He led two family members to eat from this house to that house, from the corner of the street to the end of the alley, and even made comments on each meal.

Of course, if he thinks he likes it, he can eat it a second time, and if he doesn't like it, he will naturally not come.

As for the money?

Ahem, why do you think he came out to hang out with two family members?

Don't think that this is him taking advantage of the two family members, why do you think Xue Pan would send two family members to follow him when he knew that he was out?

Everything is in plain sight!

Occasionally, he would go to the bookstore, which was where he wanted to go.

However, there are a lot of books, but he knows too few words, and it is extremely difficult to read, and he can't find anyone to ask for advice, and he can only be anxious with the book in his hand.

The only thing that allows him to 'relieve fatigue' is actually a villain book, yes, it is the kind of villain book with illustrations, although there are words, they are very simple.

This kind of book is aimed at mortals who are not very old and do not have much literacy, and most of the content is exaggerated, which is a standard cool style, and it is the most insightful.

And Mo Chengjun has become a loyal lover of villain books, and every time he goes to the bookstore, he can always read it for a long time without feeling bored, and he is very happy.

But his behavior of only reading and not buying books made the boss hate it the most, and every time he came, he was stared at viciously by the boss, and he almost kicked him out.

This gaze, even the two family members who followed couldn't stand it, and occasionally they even had a few words with Mo Chengjun to remind them.

Anyway, the money is from the master's family, they don't care, and Mo Chengjun doesn't have to care.

It's just that Mo Chengjun is very generous in other things, but this villain's book is very 'slamming the door', that is, he doesn't buy it just by looking at it, and he can't make the boss angry, but he can't really drive people away.

He is not stupid, he can take two family members, and he doesn't have to run around for a living, no matter how you look at it, he is not an ordinary person.

Of course, if you think that Mo Chengjun is just boring and hanging out, then you really wronged him.

He doesn't seem to be traveling around, but in fact, he is collecting information and trying to integrate into the world.

In the Xue family, he is so famous as an immortal master.

Even if there are some unexpected behaviors, it can be said that he has just come out of the blessed land of the immortal family and does not understand human feelings.

Even Xue Pan knew that he had no true yuan in his body and could not use his strength, but after he used the spell for the second time, he felt that he had used some secret technique.

Well, there is no need for Mo Chengjun to explain these things, naturally someone will make up for it and explain it to him clearly.

But this is only in this ordinary world, and when that female sword cultivator arrives, none of this will work.

If he didn't want to be asked, or inadvertently leak something, then he had to work hard to integrate into this world, at least before the female sword cultivator came back, he didn't show so dare.

On the other hand, he is also observing the world.

Don't think that the chatter of the restaurant and tea house can't collect information, and don't think that the business and trade on the street can't see through the world.

In fact, these are the things that best reflect the productive forces and social structure of a society, and even the living conditions of the people.

According to his observation, although the world is in an ancient society, if you want to say how low the productivity is, it is not necessarily true.

The grain store here has a complete range of grain, sufficient quantity, and the overall price is stable.

Even in the case of war on the border, there is still no trend of a sharp increase.

This at least shows that there is plenty of food here, the yield per mu is very high, and the common people are not short of food.

The food here is also very rich, with a variety of seasonings, some of which Mo Chengjun can't name, and the types of food developed from this are also extremely varied, satisfying people's appetites.

There was already a sophisticated printing and paper industry, and the books in the bookstore were not expensive, and the cost of knowledge dissemination was not too great.

There are also soaps, perfumes, fired glass, and plenty of fabrics.

In fact, all these have shown that the productivity of this world is not low.

Perhaps, it will not reach the point of mechanized production in the previous life, but this world obviously has the methods of this world, and the overall productivity has been raised.

Of course, Mo Chengjun also has the desire to learn more about it, but it is obvious that he has no channels for the time being, so he can only stay behind.

More than ten days passed in a hurry, and just when Mo Chengjun was trying to integrate himself into this world and strive to become the same as ordinary people in this world, he saw that shocking scene.

On that afternoon, the wind was beautiful and the sky was clear.

Mo Chengjun was basking in the sun in the courtyard, reading a villain book.

On the side, Xue Ling was honestly sitting behind a table and chair, spreading out a book of the same enlightenment book in front of him, and was shaking his head and reading it.

"At the beginning of people, nature is good, sex is similar, Xi is far away, no teaching, sex is migration, the way of teaching, you are specialized in ......"

Yes, this enlightenment reading is the three-character scripture, almost word for word, but why does this world have a three-character scripture?

Don't ask him, even if he doesn't know.

At this moment, there was a noisy noise, from far and near, and it became more and more chaotic.

Mo Chengjun got up quickly, listened carefully, and vaguely someone said, look at the sky, the sky ......

He instinctively looked up, looked around, and then froze.

He saw that there was endless sword light coming from the east, stretching for thousands of miles, as if dragging the glow of the ten thousand paths, cutting through the sky, and then heading west.

At that moment, there was only one poem in his mind: The sword qi spans 30,000 miles, and the sword light chills 19 continents.
