Chen Yu was in a good mood. He felt that he had finally returned Su Linsha's favor, and it was not in vain that Boss Su had sent a killing weapon thousands of miles away.

It's just that he didn't expect that he would not only fly the fat man who wanted to step on him to the outside world, but also swelled the faces of the shopkeeper, the beautiful girl, and a group of customers at the same time.

So, Chen Yu, who was in a good mood, traded the other medium-grade battle runes he had made to Mu Fan and a few people and left directly, leaving this group of people staring at each other.

After returning home and telling a little about today's experience, Chen Yu returned to his small study after dinner.

There are a few more books on the shelves in the room about combat runes, but they are no longer mid-level caps, but a few more books on the concept of high-grade battle runes.

Similarly, Chen Yu didn't know that the hearts of the Nine Elders and the others were bleeding.

Sister, they were called over by the Great Elder after Elder Su left, and they spat on their faces like a storm.

A bunch of bastards!

There is such a genius in the family, and you old bastards are still hiding it from me!

Yes, I know you don't want to leak this news, for fear that it will attract the covetousness of other families. But, you old bastards, I'm the eldest elder of the family, won't you all leak such a thing, and I will leak it out as ignorant as a three-year-old child?

Therefore, the heads of the Nine Elders and the others were almost lowered to the crotch of their pants, and they forcibly endured the angry scolding of the Great Elder for half an hour, and finally had to bleed profusely, and each handed over the books on the top-grade battle runes that they had collected for many years to Chen Yu.

This Nima, such a great genius, you still dare to hide and not give him good things? Don't you want your family to flourish?

Do you know, maybe because of your delay, the genius of the family may be stuck in the middle grade realm for a long time?

It is said that on this day, the roar of the Great Elder made the Nine Elders and the others almost lose their thoughts.

Yes, this is a little more demonic than the family genius Chen Wuxian.

In case he really ate all the mid-grade battle rune books in the past few days, and then delayed his progress because he didn't have the next books, wouldn't they be the culprits?

Therefore, Chen Yu's bookshelf has a few more books about high-grade battle runes.

"The elders are really good people. ”

Chen Yu naturally didn't know where these books came about, and he sighed in his heart.

It is worthy of being a big family, and there is unity inside, so he doesn't need to go to the pit, and he actually sent it to the door himself, these few combat high-grade rune books are what he is scarce now.

To this day, he has completely understood these middle-grade combat runes, whether it is wind attributes, fire attributes, frost, earth attributes, etc., all of them can outline the rune construction line, and he can be regarded as understanding what kind of concept is supporting it.

"Timely rain. ”

Chen Yu picked up a high-grade fire attribute battle rune concept book and began to watch it very happily.

There is a big gap between the top grade and the middle grade, although his own realm is still in the middle grade, but this does not prevent him from continuing to study runes.

Increasing combat energy is not something that happens overnight, it requires the constant use of runes to enhance it, and he now feels that his first priority is to continue to study runes, not to increase his own energy.

Of course, it's not uncommon to craft a few Battle Runes in your spare time to improve yourself.

"Hey, this top-grade battle rune is actually so much more complicated than the middle-grade one. ”

As he read more and more deeply, Chen Yu felt that what he had thought before was a little too simple, and at the same time, he knew why it was not difficult for a middle-grade monk to break through, but if he wanted to break through to the top grade, he would have to be stuck for many years.

The structure of this high-grade rune is not only a few more lines than the medium-grade rune, but more importantly, this high-grade rune needs to pass a level.

This level is like the final exam for primary school upgrades, you can't pass the test, you can pass the primary school, but this rune realm breakthrough, you can't pass the test, hehe, that's a lifetime stuck here.

"The breakthrough of the high-grade combat runes is completely different from the auxiliary class and the life class, and these extra construction lines seem to be added separately, but in fact, they are closely related to the middle-grade rune construction lines. ”

Chen Yu looked very seriously, and at the same time he frowned.

The idea is really good, the point is that it's hard to get started.

It is indeed not difficult to have a lower grade and a middle grade, which is the simplest one.

However, the top-grade battle rune requires comprehension, otherwise, even if you raise your realm to the peak of the middle grade and can refine the best mid-grade battle rune, you may not be able to understand how the top-grade battle rune is formed.

Turning over the pages one by one, this book is basically all about explaining the concept of a high-grade battle rune formation, unlike those previous books, which may record a battle rune concept on one page.

This also illustrates the difference between the high-grade and middle-grade battle runes from the side, and the difference is far away.

Time passed quickly, and an hour passed quickly, and Chen Yu still couldn't finish reading a book.

"It is estimated that the production of this high-grade battle rune cannot be done overnight. ”

Chen Yu had to sigh, even if it was him, it was not possible to deal with such a concept in an hour.

"Let's look at the others. ”

After reading the rune book in his hand, Chen Yu did not experiment for the first time, but picked up another book and continued to read it.

This is also a book with a top-grade combat rune concept, but the attributes are different.

"The difference is a bit big, only a little bit of the same vein. ”

In the middle of the night, Chen Yu finished reading the book, and then sat at the desk with his head propped up, thinking about it very seriously.

The concepts described in these two battle rune books were clear, but when he thought about it carefully, he found that although they were both concepts of battle runes, only a small part of them were interconnected, and most of them were incompatible.

This made him feel that he had a long way to go, and it was indeed difficult to fuse the runes of two different philosophies together.

"Forget it, just study it slowly. ”

Fortunately, Chen Yu is open-minded, and at the same time, he also knows that this kind of subversive thing cannot be solved overnight.

In a blink of an eye, seven days have passed.

Mu Fan and the other sons and sons left the town four days ago and went back to their big city.

In the past few days, in addition to taking the time to go to his own store every day to deliver the runes that customers need, Chen Yu spends most of his time at home studying these high-grade rune concept books.

And Lin Hao, the Lin family's store has not opened for so many days, and Chen Yu has not seen it, so he doesn't know what to do.

Of course, Chen Yu didn't have the heart to gossip, he ******** focused on studying rune books.

And in the past few days, Chen Yu has also accumulated the energy in his body to the peak of the middle grade in the next three days.

After all, without the consumption of Mu Fan and other sons, it would be difficult for him to sell these medium-grade top-grade combat runes, so it would be better to use them to improve his strength.

Up to now, Chen Yu has become much stronger both mentally and physically, and his gestures have made Chen Dad feel that he has lived in vain for so many years.

"It's been a bit dull. ”

Chen Yu was lying on the bed, and the store didn't need him to manage it for the time being, after all, it hadn't been promoted to the second level, and there would be no too tall guests coming in, so the medium-grade battle runes couldn't be sold at all.

And the inferior one, it is enough to have Chenxing take care of it alone, after all, it is just a wholesaler, and it does not need too many manpower.

Coupled with the study of high-grade runes, he has only touched a trace of mystery now, and there is still a piece of paper away from making it, which requires a breakthrough point.

This caused Chen Yu to feel that he was a little idle, and he had also carefully studied the high-grade auxiliary rune, which did not help him much.

"Bastard boy, are you still sleeping? Don't get me up yet, the little strong man is here!"

Just when Chen Yu was bored and lying on the bed with his eyes closed, Chen's father broke into the door with a 'bang', and his big voice also howled.

"Little Hadron?"

Chen Yu opened his eyes, he was a little scorched by the thunder.

"What kind of strange name is this? And the point is, who is it? How can it make Daddy so anxious. ”

Chen Yu looked at his father suspiciously, trying to find out which big man this is, not only with such a strange name, but also with such a noble identity.

"Bastard, your father-in-law is here, why don't you hurry up for Lao Tzu and me!"

"Lying ...... Groove!"

Chen Yu was excited, and turned over and got up suddenly, which ......
