A thought suddenly flashed in Chu Du's heart, and as soon as he gritted his teeth, he could only try this.

"Ding, congratulations to the host, trigger the new function of this system. Chu Du immediately said in a cold mechanical voice.

Chu Fan, who was contemplating the exercises, was immediately awakened, and when he understood what was happening, he immediately became excited: "Triggered a new function?"

The voice of the "system" immediately sounded: "Ding, congratulations to the host, trigger the new function [Exercise Optimization]." ”

"Ding, system prompt, exercise optimization: You can optimize the exercises, repair the defects of the exercises, improve the level of the exercises, and consume the pressure value when you use it, and deduct the pressure value from the power of the required optimization exercises. ”

After Chu Fan heard the sound of the system, he was about to jump up excitedly, and laughed wildly in his heart: "Hahaha, Lao Tzu has nothing to say, this luck is simply against the sky, I was still worried just now that no one has cultivated this exercise before, but theoretically it can grow infinitely, and there may be great danger, and now it immediately triggers the function of the system's [Exercise Optimization], which ...... I'm so straight is a big hanger. ”

Chu Du: ......

You have to know that you are a big hanger!

"System, you start optimizing. ”

Chu Fan immediately made a decision to let the system optimize this hidden danger exercise, his heart was still excited, everything that happened tonight was simply a wave of climax after a wave of climax, first the lottery drew the treasure of the holy medicine level, Chu Qingmei sent so many pills, and then his foundation was reborn and changed, these were already cool enough, and then solved the hidden danger of the old grandfather that hindered his cultivation, but he didn't expect that after solving it, he even obtained the [Sword Technique] This kind of anti-heaven exercise, this is not the end, after obtaining the sword technique, it triggers the function of system optimization exercises, which can solve the hidden dangers of the sword technique.

"Hahaha, this kind of open life, it's so cool, system, hurry up and optimize this exercise for me. Chu Du said excitedly.

Chu Fan was excited, and Chu Du's heart was also excited, he didn't expect that Chu Fan would agree to optimize the exercises so easily.

He immediately said in a cold mechanical voice of the system, "Please recite the exercises silently in your heart. ”

Chu Du's heart was beating, as long as Chu Fan's mind appeared in the sword technique, he would be able to write it all down in an instant.

"Huh, system, can't you just scan my memory?" Chu Fan asked in wonder.

Chu Du immediately sneered, why do you think Lao Tzu doesn't want to? Lao Tzu is a fake system, using his head to scan your memory?

If the old man really has this ability, why are he still fooling you here?

Chu Du immediately replied: "This system is a genuine system, not a low-cost black-hearted system developed by those unscrupulous black-hearted developers, according to Article 3282 of the Host Privacy Law of the Universe Alliance: Regardless of whether the host agrees or not, the system is prohibited from doing the immoral behavior of scanning the host's memory privacy, and those who violate it will be humanely destroyed!"

Made, in the future, you must practice a soul-searching technique, and when the time comes, you will directly scan your memory!

"Hmm, the Cosmic Alliance, the host privacy, I see, hahaha. ”

Chu Fan was even happier, although he was very puzzled that he had not heard of these things that the "system" said, but he did not suspect anything, and silently recited them in his heart and exercises.

"Knock! knock!"

Chu Du felt that his heart was beating vigorously, like a cowhide drum, and his heart was extremely surprised, and he immediately sensed the [Sword Technique] against the sky.

Chu Du took a deep breath, closed his eyes, and memorized this technique in his mind.

With the strength of his soul, in fact, he didn't have to do it at all, and he would not forget almost everything he had seen, but this exercise was too amazing, so Chu Du was afraid of losing it.

"Have you optimized the system?"

Chu Fan's voice rang out, and he couldn't wait to cultivate this powerful technique.

This exercise is directly named [Sword Technique], just by this name, you know how extraordinary this exercise is, especially with the possibility of infinite growth, getting stronger and stronger, it is simply a necessary skill for the protagonist.

Hearing his words, Chu Du immediately sneered: "The realm of the two of us is almost the same, both are in the opening period of the veins of the vegetables, what can Lao Tzu optimize?"

Chu Fan opened the five tricks, three years ago, Xiuwei began to retreat weirdly, and now there is only one trick left, while Chu Du is the previous five tricks, but he blew himself up, and he didn't know anything, and both of them were not good at cooking.

However, of course, Chu Du couldn't tell Chu Fan like this.

He immediately had a way in his mind, and then passed on the "optimized" exercises to Chu Fan.

Chu Fan hurriedly wrote it down excitedly, and after reading it, Chu Fan was stunned: "System, why do I feel that something is wrong? You don't seem to have any optimization at all...... No, if anything, it's ...... This seems to be practiced backwards, right?"

Chu Fan was stunned, and there was an incredible look in his eyes.

The [Sword Technique] after the "optimization" passed on to him by the system turned out to be a reverse practice of this technique!

This......

This system is mentally retarded!

Hearing this, Chu Du immediately sneered in his heart, this host is really not picky, he just spent a lot of time reciting this exercise.

His cultivation is even better than Chu Fan's, if he doesn't do this, how can he show that this exercise has been "optimized" by him?

Moreover, let's not talk about whether he has the ability to optimize, even if he really has, if he only changes a small place, can it reflect the awesomeness of his system?

How good it is now, let you directly reverse practice, and immediately it seems that the system is a lot taller!

As for whether the reverse training can be successful, will there be any consequences?

Hehe, anyway, let Chu Fan practice.

It's just that he definitely can't explain it to Chu Fan like this, as for how to explain it, Chu Du has already thought about it.

"I can't imagine that the host is so smart, and I can see at a glance that the optimized exercise is practiced in reverse, in fact, this is the biggest conspiracy of this exercise, because this exercise is too powerful, coveted by countless people, the person who recorded this exercise, in order to avoid this exercise from being obtained by outsiders, so he deliberately recorded it in reverse, if the uninformed person practiced, he would definitely die of violence in the end!
