Lu Yu absentmindedly accompanied Lu Xiaoxiao for a morning, and it wasn't until it was time for lunch that Lu Xiaoxiao let him go, not that Lu Xiaoxiao didn't want to continue shopping, but they were both hungry after a morning of shopping, and there was no money in their pockets to eat outside, so they could only go back home to eat.

When he arrived at home, Lu Yu hurriedly ate and ran back to his room, took out the first copy of "The Body of Black Iron" and read it.

"System, is it possible to cultivate now?"

"Cultivating the Body of Black Iron requires paying 100 points, do you want to cultivate?"

"Cultivation"

As soon as Lu Yu's words fell, he suddenly felt a tingling sensation all over his body from the inside out, as if there was a faint electric current swimming throughout his body, and then this current became larger in vain, Lu Yu also felt a sharp pain surging from all over his body, and then he felt that the whole person seemed to be kneaded vigorously by a giant in his hand, as if he was about to crush his whole person, that kind of heart-rending pain made Lu Yu's whole person almost collapse, and after living two lifetimes, it was the first time he experienced such intense pain, and his snot and tears flowed from his face.

About 2 minutes passed, which was not a long time, but for Lu Yu, it seemed like centuries had passed, and the pain slowly subsided, but his whole body was completely paralyzed on the bed.

"Ding, congratulations to the host "Body of Black Iron" Xiaocheng."

"C, you m system, why don't you tell me it hurts so much." Lu Yu scolded with a crying voice, it was not that he was weak, but that this kind of pain had exceeded the limit that an ordinary person could bear, especially since he was still an otaku who was afraid of pain and death.

"Rest assured, host, only the first reinforcement will cause physical discomfort."

Lu Yu didn't want to talk anymore, he lay on the bed in a daze, and after more than half an hour, his body fully recovered, reopened the layout of the system, and found that there had been changes.

Host: Lu Yu

Stamina: 122/132+

Spiritual Power: 0/0+

Spirit: 55/60+

Credits: 1474

Carry-on space: 1 cubic meter

Skill: "Body of Black Iron" - Xiaocheng Realm.

The physical strength has been strengthened by him a total of 5 times since the morning, 2 points each time, it should have been 122 points, and it seems that the extra 10 is because of the cultivation of "Black Iron Body". The spiritual power is also a little more, but I didn't expect that practicing this exercise would also increase the spiritual power, Lu Yu was a little surprised.

As for the big difference between the two values, it was completely caused by the severe pain just now, so Lu Yu didn't feel any discomfort. Just wait a few hours and slowly recover.

It's just that the mental power has broken through so much unconsciously, but it has saved a lot of points, otherwise it will definitely be a bottleneck when it breaks through 60 points, but I didn't expect it to be a blessing in disguise.

"System, how many points does it take to strengthen to Dacheng?"

"500 points can strengthen "Black Iron Body" to the fullest."

When Lu Yu heard this, he gritted his teeth and said, "Strengthen to Dacheng." "Although 500 points is a lot, it is not as important as a small life, whether it is in the movie world or in the real world, it doesn't seem to be so safe, or it is important to save your life.

"Sure reinforcement?"

"Wait a minute, you're sure it won't hurt as much this time, right?"

"Yes"

"Alright then, strengthen."

As soon as the words fell, Lu Yu felt that numbness spread all over his body, and immediately his heart tightened, Nima, why is it the same as the beginning just now? But after waiting for a while, I found that it didn't hurt so much, but I felt very comfortable, and I immediately relaxed.

"Ding, congratulations to the host, "Body of Black Iron" is a success."

"That's it? Don't feel like it? Looking down at his arms and thighs, it seemed that there was no difference from just now, but his strength had increased a lot.

"System, it is said that Dacheng's "Body of Black Iron" is difficult to hurt by the sword, is it true?"

"It's true that ordinary swords can't cause any damage to the host, but the true qi spiritual power of a martial artist above level 4 can cause damage to the host, but it will have a certain reduction effect."

"That's not bad, how many points does it take to strengthen to the consummation level?"

"1000 points."

When Lu Yu heard this, he pondered for a while, but he still gave up, and now there are 974 points left, which doesn't seem to be enough, "By the way, how can you upgrade the exercise of "The Body of Black Iron"?" ”

"After the host cultivates to perfection, he only needs to spend a hundred points to level up."

"Come on, it seems that you don't have to think about it. But now Dacheng's "Body of Black Iron" is completely enough, let's wait for the next time the world comes out. "Strengthening the Body of Black Iron to Dacheng Lu Yu is quite satisfied in his heart, because it is not so easy to cultivate a technique to Dacheng. If you don't have a few years or even more than ten years of penance, don't even think about it.

Looking at the tool knife on the desk, Lu Yu had the heart to pick it up and give it a try, but after a stroke, he still didn't dare to try it in the end, in case he made a cut, it would hurt a lot.

took out the last exercise "Extreme Cool Running", Lu Yu asked the system: "It won't hurt so much to learn this, right?" ”

"No, it won't."

"Okay, let's cultivate."

"Are you sure you want to spend 50 points on cultivation?"

"Huh? Why do you need 50 points for this? Lu Yu asked suspiciously, what about the 100 points just now, why did the price drop drop, could it be that the conscience of the system found out?

"Depending on the value of the exercises, the points required are different."

So Lu Yu understood, that is, "The Body of Black Iron" is worth more than "Extreme Running", and the value is much higher, so the points needed for strengthening are more, it seems that although the way of cultivation of "The Body of Black Iron" is a bit perverted, the effect is definitely top-notch.

"Fortify."

After waiting for a while, Lu Yu didn't feel anything other than feeling a little hot.

"Ding, congratulations to the host "Extreme Cool Run" Xiaocheng."

Is this small? When I move my arms and legs, there seems to be no difference, and my strength has not increased, but if I feel it carefully, it seems that it is indeed a lot lighter than before.

Since the effect is not so obvious, then try one level higher. "How many points do I need for the next level?"

"200 points can be strengthened to Dacheng." Lu Yu held his chin in his hand, thinking about being despised by his teachers and classmates during the assessment that day, and smiled, "Look at my skill after it is strengthened to Dacheng, if I don't run for 5 seconds in 100 meters, I will lose, and then I will be shocked by your jaw." ”

"Intensify."

"Ding, congratulations to the host for the success of "Speed Running".

"How many points do I need for the final level of consummation?"

"500 points."

"Oh, it's okay, I'll ask."

Looking at the remaining 724 points in the end, Lu Yu gritted his teeth and gave up his plan to continue strengthening, there are still 2 months to cross the movie world again, this point is better to save a little bit to strengthen himself, and the next time he goes to the movie world, it would be a pity if he met something valuable and didn't have points to bring back
