In the following days, in addition to attending classes and cultivating every day, Su Mu spent most of the rest of his time reading the basic books needed to break through the foundation building application.

Even the time for Kevin's language lessons was much less. Fortunately, Kevin knew that he was preparing to build a foundation, and he was not dissatisfied, let alone asked him to refund his tuition.

Five days have passed in a blink of an eye, and Su Mu has finally finished reading all the basic books needed to break through the foundation building application.

In the middle, I also used the fragmented time to read a book of "Spirit Ginseng Cultivation Techniques", and learned a few tricks from it, and finally served the spirit ginseng comfortably, and the wilting situation was greatly improved, not only the leaves stood up, but the roots also grew a few more.

I just don't know when it will blossom and bear fruit.

Su Mu is also looking forward to cultivating a wave, planting spiritual ginseng in the yard, and then taking photos from time to time to send them to the circle of friends, pretending to be forced quietly.

After raising all the basic books to a score of 10 (flawless), Su Mu tried to break through the foundation building application again.

This time it worked!

The rain of data was surging wildly, and when it returned to normal, Su Mu took a closer look and found that there were no major changes to the evaluation of foundation building application, except for an extra parenthesis at the end, which read: Breakthrough +1.

Breakthrough +1?

Seeing these words, the corners of Su Mu's eyes twitched.

Since there is a breakthrough +1, is there still a breakthrough of +2, +3 ......?

Will there still be a failure of the breakthrough?

If the breakthrough fails, will no fees be refunded?

This, this, this......

He was all too familiar with this routine - all of them had been played during the planning.

What is this? Retribution?

Su Mu couldn't help but shudder.

He tried to continue to break through the foundation building application, and the result was that he saw this passage: [This knowledge has been broken through to the maximum]

Instantly understood.

It is impossible to break through the application of foundation building, but other knowledge is really possible +2 or +3...... Such a breakthrough!

Well, really retribution!

Su Mu shook his head with a wry smile, took out his phone, and checked the cost of the breakthrough.

Breakthroughs are much more expensive than upgrades, costing two million. Fortunately, there is an online store that makes a lot of money, otherwise it would not be enough to rely on the little savings from the previous one.

This is only a level of knowledge, if it is a second, third, or even higher level, break through once, I don't know how much it will cost?

However, although the cost is high, it is well worth it.

After the breakthrough in the knowledge of foundation building and application, it is a great improvement in all aspects! Such an achievement, let alone two million, is worth more.

From this point of view, although there are many tricks to deceive Krypton, like him, they are all genuine and conscientious.

Moreover, this 'research fund', Su Mu has already thought of countermeasures, and he will definitely be able to earn it back with interest.

After completing the breakthrough, Su Mu did not rush to the foundation building field to start building the foundation, but went to the library first.

As the 'honored guest' of the library, as soon as he entered the library, he was immediately warmly welcomed by the book spirit.

Although it was not the book spirit that received him this time, his enthusiasm was not diminished at all, after all, he was here and had the prestige of respecting him.

"Our dear friend, do you need anything to come this time?"

The book spirit flew up and down in front of Su Mu, and if it had a hand, it would definitely give Su Mu a warm hug.

Su Mu returned the books he had borrowed before, and then asked, "Is there a design plan for the foundation building circle in the library?" ”

Shujing was a little surprised: "Yes, yes, but what do you think this is for? Isn't there a ready-made foundation building circle in the school? Do you still want to make one yourself? I advise you to dispel this idea." The foundation building circle is a third-level A, and with your current cultivation, you can't build it at all, and it's also very expensive. ”

"The foundation building circle is a third-level A-grade?"

Su Mu frowned slightly, this level of magic circle, with his current cultivation, he really couldn't make it even if he learned it.

But if you give up like this, you don't feel very willing.

He remembered the outsourced production method of the fleshy magic weapon, and asked, "Is the foundation building circle integrally formed, or is it detachable and assembled?"

"Of course, it's a one-piece mold. Shujing replied.

Well, that last bit of hope is gone. If it is disassembled and assembled, it can also be outsourced to find an OEM.

Su Mu could only give up and say goodbye to Shujing, but just as he turned around to leave, Shujing suddenly stopped him: "Wait a minute, friend." ”

"What's wrong?" Su Mu stopped.

"Are you studying the foundation building circle to build the foundation?"

"That's right. Su Mu nodded, isn't this an obvious thing.

"While we can't help you learn the foundation building circle, we can show you how to choose the best foundation building room. ”

Su Mu was stunned when he heard this: "What do you mean?

"Of course there is a difference......"

Shujing immediately introduced it, and Su Mu learned after listening to it that there was a large spirit gathering array hidden under the school's foundation building field.

It is precisely with this Spirit Gathering Array that the foundation building field has a steady supply of spiritual power, and it can support one hundred and eight foundation building rooms for the students to use.

What connects the Spirit Gathering Circle and the foundation building room is a specially laid spiritual energy transmission pipe. This pipe is not one-to-one, but like the water supply pipe in the community, it is sent by a main pipe to the foundation construction site, and then diverted to different branch pipes.

This has resulted in different foundation building chambers, and there are differences in the intensity and concentration of the spiritual energy distributed.

Just like the water supply in the community, the water pressure of the users on the ground floor is often greater than that on other floors. Once the water pressure is insufficient, it is likely that the ground floor will not be affected, and the middle and high floors will have to be cut off.

Of course, in the foundation building field, the aura of each foundation building room is not very different, and the students can't even notice it, but it will indeed have a certain impact on the foundation building.

After the introduction, Shujing made a summary: "The supervisor who supplies the aura is laid all the way from the gate of the foundation building field. Therefore, the closer to the foundation building room as the gate, the higher the quality of the aura obtained. ”

"When you build the foundation, remember to choose the foundation building room close to the gate, and don't choose those far away. ”

Su Mu nodded repeatedly.

I am afraid that even the teachers in the school may not know about these things. It is only these book spirits who stay in the library every day to deal with all kinds of books, drawings, and materials that they can know so clearly.

"I see, thanks for the pointers. ”

Su Mu's thanks came from the bottom of his heart.

If it weren't for the guidance of the book, he wouldn't have known that the selection of foundation building rooms was also exquisite, and he thought that the effect of all foundation building rooms would be the same.

"You're welcome, you're really welcome, hahaha, come, say it again, it really makes me happy to listen. ”

......

Well, obviously, Shujing's gratitude to Su Mu is very useful.

Bidding farewell to the book spirit and leaving the library, Su Mu went straight back to the small courtyard.

He turned on his mobile phone, placed an order on the school's APP, bought various materials for making concentrating incense, and then called Yang Lin and the teachers one by one to ask for foundation leave.
