Early the next morning, Su Yan and Huang Xiaobing sent Xu Youyuan to the Academy of Literature together, and then they went to Qingcheng Baiyi Pavilion together to exchange for the Double Cultivation Pill and Zhuangyuan Pill, and after going home and feeding the ape beasts, they started to cultivate directly, and by the way, they put the group of ape beasts aside and trained them.

Xu Youyuan will not come back at noon, and he will not waste the effect of their double cultivation pill.

After Su Yan finished cultivating for a while, he checked his own state, his source qi cultivation had accumulated to 1426, this progress speed was very fast, if he kept it, it was estimated that he could be promoted to the second layer of open source before May next year, which has already surpassed the vast majority of people.

However, Su Yan also calculated that if he and Huang Xiaobing slacked off occasionally, he estimated that he would not be promoted until July or August next year, although it was still faster than many people, but it would be much slower after all.

Fortunately, after waiting for the formation of the "Substitute Training Ape Beast" exercises, they don't have to worry about slacking off.

"It's a pity, buying a fierce beast cub, even the most convenient kind is still very expensive, if the reproduction rate of those three types of fierce beasts becomes higher, if the price of the most common fierce beast in the three types of fierce beasts drops in ten years, the human race is estimated to have many more thirty-year-old Spirit Realm powerhouses, and then the sea beasts are endless, what is there to worry about?"

By reading some miscellaneous books and adding his own calculations, Su Yan felt that there might be 1~300 million people above the sixth level of open source in the mainland, and more than one million of these people who had just reached the age of fifty would go to the frontline battlefield of the battle of sea and land every year.

In the ten years of the battlefield, tens of thousands to hundreds of thousands of these people may be killed, hundreds of thousands of people will be injured, and only about one or two hundred thousand will return to the Terran city unharmed.

This loss ratio is very large!

But what if it's a million Spirit Realms that go to war every year?

Everything will be different, and the number of Terran combat casualties will inevitably become negligible, or even completely non-existent.

At that time, the Terrans could even fatten up the sea beasts and then kill them, and when they all grew into tenth-order sea beasts, wouldn't the Terrans have a lot of high-level materials?

It's just that I don't know if these sea beasts will break through the tenth order and reach a level equivalent to the spirit realm, and in the books Su Yan has read, there are only simple records of spirit beasts and king beasts in ancient times.

But after the rise of the human race, those spirit beasts and king beasts seemed to have disappeared completely, and I don't know if it was because the upper combat power of the human race was too strong now.

After thinking about it briefly, Su Yan entered the cultivation state again, while Huang Xiaobing was always in the cultivation state, much more attentive than Su Yan.

After cultivating for a total of three hours, they put the ape beast away, got up and moved their muscles and bones, and went downstairs to eat and rest for a while before they continued to cultivate.

......

In the evening, after Su Yan and Huang Xiaobing went to the literary academy where Xu Youyuan was studying to pick her up, the three of them went to Xu Changshou's house for dinner together, and then Xu Changshou talked to them about "Longevity Sutra" for another night.

After all the key points were finished, Xu Changshou said: "Okay, I have already told you the important places, and you can concentrate on reading the third article in the future until you comprehend the art of asking fate...... In the future, you will take Yuanyuan to stay in District 5 and don't come out again. ”

At this time, Xu Youyuan ran over and interjected and asked, "Father, mother, why don't you go to live in the fifth district?

Xu Changshou looked at his daughter, who was worried about his safety, and couldn't help but smile warmly, he explained to Xu Youyuan in a soft voice: "Yuanyuan, there are rules in the Wanyuan Continent, people over fifty years old must guard the front line, if something happens near the Terran city, we must also guard the rear, and the higher the realm, the more people must stay outside, and those above the fifth level of the open source must even go out of the city to defend." ”

Xu Youyuan wondered, is there still such a rule in the Wanyuan Continent?

Su Yan added at this time: "Yuanyuan, this rule, in fact, in the last year of your study in the Academy of Literature, the gentleman in the Academy of Literature will explain it in detail, and now you don't need to pay attention to this." ”

Then, Su Yan said hello to Xu Changshou and He Qianxi, and took Huang Xiaobing and Xu Youyuan back to their temporary residence in District 5.

In the future, they should try to stay in District 5 and not run out.

......

On June 15, Xu Youyuan had a holiday, and she stayed at home with Su Yan and Huang Xiaobing for most of the rest of the time, and she found that her brother Su Yan and Bingbing's sister-in-law liked cultivation as much as her mother.

And the two of them also like to study the exercise books.

Soaking with them, Xu Youyuan felt that she was more motivated to study and cultivate, she followed the cultivation when they cultivated, and she followed the study when they were studying, and she lived a more fulfilling and happy life than before.

It's just that the exercise books that her brother and sister-in-law read are too ugly, she can't read them, and it's very uncomfortable to read the textbooks, so she asked Su Yan and Huang Xiaobing if there were any books other than the exercise books.

Storybooks are the best!

Huang Xiaobing thought about it, took out her treasured "The Queen's Self-cultivation" and "The Adventures of Luoluo", and said, "Read it slowly, these two sets of books are very interesting." ”

Xu Youyuan happily took the books and left, these two sets of books became Xu Youyuan's best reading materials at night, and she finally didn't have to look at Su Yan and Huang Xiaobing to read the exercise books and she could only be bored in a daze.

And seeing Huang Xiaobing take out these two sets of books, Su Yan, who was studying "The Law of the Same Origin", suddenly remembered these two sets of books, and he had just read the beginning.

He thought to himself, why don't you continue to flip through it, there is still something in it that has broadened his horizons.

And when they were indulging in cultivation and studying, Xu Changshou would occasionally bring He Qianxi over to see Xu Youyuan, so that Xu Youyuan would know that they were all there.

On such a day, Su Yan and Huang Xiaobing were worried, when would that unknown trouble come back, and whether Xu Changshou had something to do with the sea beast?

After all, Xu Changshou was not allowed by him, so he could only predict that Qingcheng was in trouble, and he still had to wait for Baiyi Pavilion to issue a notice before going to school

It's just that there was no response from the door at home, so Su Yan and Huang Xiaobing had no choice but to take Xu Youyuan to cultivate and study with peace of mind.

The study of the "Homologous Law" is indeed very difficult, and they still haven't conquered it until June 20, but they already have a little experience, and it is expected that they can find some ways to find it before June 25, and then start trying to cultivate in July.

When the time comes, they can start to lay down their cultivation careers and spend more time studying the exercises and refining the combat techniques.

You can even take a break to read miscellaneous books once in a while, and find books related to the open source promotion spirit realm to prepare for future promotions.

Compared with the seriousness of the "Homologous Law", during this time, they put down the study and research of the "Longevity Sutra", and pushed the cultivation of the "Asking Fate Technique" to the back.

After all, for them, the urgency and importance of studying and cultivating the "Asking Fate Technique" at the moment are not as high as the "Homologous Law".

And while they were working the Decree of the Same Origin, on June 25th, the door of their house lit up, and a green dot the size of a baby's fist appeared on the door.

Xu Youyuan, who was reading a storybook, saw that Su Yan and Huang Xiaobing were concentrating on reading the book, so Xu Youyuan didn't call them, ran over and poked the green dot with her finger.
