A blue light flashed, and the blue plus sign behind the 'Light Cloud Sleeve' jumped suddenly, and Chen Han's heart also jumped.

Sure enough, there was no surprise to him, a stream of data poured into his mind, all of them were some applications and skills of light skills, this time the data flow was not too big, probably because the improvement was not so obvious, Chen Han had no other discomfort except for a slight swelling pain.

After so many times of strengthening, Chen Han can be regarded as summing up some rules, for now, improving internal strength is only to increase the content of internal force in the body, while improving swordsmanship and the like is some proficiency and memory and experience summary of martial arts.

The former doesn't have any pain for himself, and even has a special feeling of refreshment when the internal force surges in the body, but the latter is the complete opposite, when the huge memory data flows into the mind, the taste is needless to say.

However, although the pain is a little painful, it is still worth it, after all, these things are not like internal force, they need a long time to accumulate before they can be gained, and the sword soul space has greatly increased this speed, and the benefits are naturally needless to say.

The memory in his mind gradually became clear, and many light skill techniques, and even the unique application method of 'Light Cloud Sleeve', also appeared in his mind, which suddenly made Chen Han suddenly enlightened, and at the same time, the cultivation level of 'Light Cloud Sleeve' was instantly raised to the second layer.

"Huh, what's going on?" Chen Han's brows furrowed slightly. What is not quite the same as when he improved his sword technique was that after this ascension, after the second layer's internal force operation method appeared in his mind, Chen Han found that this operation method was completely different from Professor Zhao Yan's own before.

"What went wrong?" Chen Han was a little confused for a while, but before he could think about this problem clearly, he found another thing that made his eyeballs almost fall out.

He found that his potential point turned out to be 0!

That's right, it's 0. Chen Han looked at it several times, but he didn't see any number before 0, there was no 1 and no 2, it was just a bare 0.

"You're a cheating daddy!" Even if he is as calm as Chen Han, he directly burst into foul language.

You know, he just wanted to improve this 'Light Cloud Sleeve' first to increase his life-saving ability, and then see if the remaining potential points could improve the 'Longquan Tu Qingfeng' or the 'Great Yan Heaven Intercepting Sword', but he never expected that just raising the 'Light Cloud Sleeve' by one layer would use up a full twenty-six potential points.

What is the concept of twenty-six points, even if it is as strong as 'Longquan Tu Qingfeng', which Chen Han speculated to be either B-level or A-level swordsmanship, it can be promoted from the ninth layer to the Great Perfection.

Even if he didn't care about this, the incomparably magical 'Great Yan Heaven Intercepting Sword' was a swordsmanship that even Lin Qinglan hadn't mastered, but it was only an E-level 'Light Cloud Sleeve' that was raised from the first layer to the second layer? Running out of 26 credits? How did Chen Han not scold people angrily?

Forcibly suppressing the fire in his heart, Chen Han closed his eyes again, immersed his mind in the internal force operation method that had just appeared on the second layer, and carefully sorted it out, he also figured out that the possibility of this 'light cloud sleeve' appearing in this situation should be in the change of this operation method.

Thinking of this, Chen Han secretly said in his heart: "I want to see what changes you make, if it doesn't have much use, I'd rather not improve this thing in the future, and find an opportunity to change another light skill......

He made up his mind in his heart, and secretly mentioned the operation method that had just appeared in his mind, Chen Han frowned slightly: "What's going on?" ”

With a low whisper, Chen Han was once again immersed in the exercise that was completely different from the previous one. His expression was wonderful, sometimes frowning and contemplative, sometimes his expression changed drastically, sometimes the corners of his mouth were lightly raised, and his face was smiling.

Finally, almost two hours later.

Chen Han slowly exhaled a breath with a pale, with a hint of ecstasy in his eyes, sure enough, this sword soul space will never let himself down, this time these twenty-six credits, Chen Han can only say one word, that is value!

Although the function of the 'Light Cloud Sleeve' has not changed in any way, there is a jaw-dropping change.

If the previous 'light cloud sleeve' wants to operate, it must have internal force to flow through the whole body to achieve the effect of 'light', and make it drive the whole body, so that it can achieve a fast speed and light body effect, so that the forward, vertical leap and movement can get a certain bonus.

But these have a very important prerequisite, that is, the internal force must run the whole body, in the middle, although the internal force runs extremely fast, but after all, it still has to be transmitted in a few tenths of a second.

And this second layer of light cloud sleeves is completely different, not that there is no need for internal force transportation, if it is just like this, of course Chen Han will not be so happy.

The operation method of the 'Light Cloud Sleeve' in the memory left by the Sword Soul Space was enough to reach the point of shocking the world, and even Chen Han still thought that this was not a dream.

No internal forces are required!

That's right, this is the function of the 'light cloud sleeve' now, the second layer of the light cloud sleeve, not only the speed has increased by more than one grade, but also the operation will not consume internal force, which is almost a terrifying effect that all martial artists dare not believe, but all light skills are driven by internal force, and under the urging of internal force, of course, there will be some loss.

But now this improved version of the 'Light Cloud Sleeve' has no worries about this at all, and even in a way, Chen Han can always maintain the operation of the Light Cloud Sleeve, which is a bit terrifying.

'Huh, so what? Chen Han dragged his chin and thought of another possibility: "Can I learn another kind of light skill?" Calculated in this way, superimposed with the light cloud sleeves, how terrifying is its speed? ”

"Huh? What's going on? Soon, Chen Han discovered another miraculous thing, he closed his eyes, and suddenly found that the light cloud sleeve (second layer), which originally belonged to the line of light gong, suddenly moved up one place. Moved to the special top of the same line as the Sword Sutra!

"Is that really going on?" Chen Han was shocked, this improved light cloud sleeve really no longer belongs to light work, but in this 'special' industry.

After sorting out everything, Chen Han slowly mobilized the internal force in his body, wanting to feel this 'light skill' that could be said to be a world different from before

Still the same as before, the surging internal force slowly traveled throughout the body, flowing through different meridians according to the operation mode of the internal force of the second layer.
