More than a month has passed, and Xiao Lingfei is officially two years old, and on the surface he looks about three and a half years old. In these more than 30 days, Ling Fei did not carry out any cultivation, but seriously studied various theoretical knowledge every day, such as combat concealment, ambush, ninjas must learn to hide their breath, that is, attack opponents in a concealed state, and make traps, etc., including learning the history of ninjas, the necessary knowledge and abilities of ninjas, Xiao Ling Fei is like a sponge and hungry for continuous learning.

In the ninja school, the second half of the afternoon is free time, and in the world of ninjas, the free time of the school is completely different from that of the earth. On Earth, free play in school is where students mostly engage in a series of sports activities, such as playing basketball, football, baseball, walking, etc., while the ninja school says that the world of ninjas, even for children who are not ninjas, play mostly about ninjas.

Children like to play the game of playing ninjas, hunting down fugitives, and practicing ninja equipment, such as kunai, shuriken, and the upper limit of physical strength, and the rest is some of the initial number of practice machines to refine chakra. Ninja schools exist to train and select children who are qualified to become ninjas.

On this day, Ling Fei stood alone on the runway, if you look closely, you will find that his entire calf is tied with a lead plate, the lead plate is a small cuboid, weighing about 0.5 kilograms, one leg is tied with two lead plates, two legs are two kilograms, there are attached weights on the upper body, all are specially tailored weight-bearing training clothes, the same 0.5 lead plates have lead plates on both sides of the abdomen, waist, and waist, a total of four kilograms.

Moreover, there is a lead plate on each of the two arms, and the weight of several pieces adds up, the legs are four kilograms, the body is four kilograms, and the arms are one kilogram, and the weight of the whole body increases by about nine kilograms. And the one who carries such a weight is a child, and if others know about it, they will be scared to death.

Ling Fei's weight bearing is naturally for training, more than 30 days, he first carried out some simple weights, and then increased step by step, although it sounds very scary, but for Ling Fei who has the power of the devil, this is a good opportunity to adapt, can quickly increase the strength, as time goes by, the weight of Ling Fei's whole body becomes heavier little by little, legs, arms, upper body, super intensity training greatly increases the burden on the body, every training makes Ling Fei painful.

However, during the rest process after training, the Majin genes hidden in the body gradually awakened due to the stimulation of the body's burden, and the super physical strength and recovery power were gradually developed.

If this is not the case, the body of a small child like Xiao Ling Fei cannot withstand high-intensity training, and because of this, Ling Fei's physique can quickly improve in the collapse, on the surface it is close to the physical strength of an ordinary adult, although it is equivalent to a four-year-old child on the surface, it is much stronger than an ordinary child.

Ling Fei walks briskly every day under weights, tries to run after getting used to it, and some simple exercises, such as: punches, push-ups, sit-ups, pull-ups, etc., are carried out under weights, not only these, but also weight-bearing tree climbing and swimming. He was bigger than the average child, and he ate almost twice as much, and there was a firmness and maturity between his eyebrows that did not match his age.

Today, Ling Fei is planning to conduct an extreme physical fitness test, that is, in order to know where the limit is, and in order to challenge the limit, he runs around the track quickly under weight, not only to run as many laps as possible, but also to run as fast as possible.

On the runway, a small figure drove his legs, running with a little difficulty, Xiao Lingfei's eyes were firm, his little face was slightly red, drops of sweat slowly fell down his cheeks, the clothes on his body were gradually wet with sweat, his chest rose and fell, and his breathing became very heavy.

The track of the ninja school is about 400 meters in a circle, and Xiao Ling Fei ran fifty laps under weight, a total of 20 kilometers, these 20 kilometers of running, he felt that his body was getting more and more tired, and his face turned pale from the original ruddy, no matter how strong the recovery power was, Ling Fei was now only a two-year-old ghost.

Moreover, his demon gene has not yet been fully awakened, Xiao Lingfei just felt a burst of dizziness coming into his mind, his body became heavier and heavier, and more and more weak, at this moment, a soft female voice came: "Master, because you have carried out a month of special training, your physical skills have reached the level of Zhongnin, and there is good news, because the body is beyond the limit, the body can be transformed, the master can choose, strength, speed, endurance three, which one does the master choose?"

Ling Fei felt a little strange, according to some similar novels in his previous life, he generally carried out a comprehensive physical transformation, although there were exceptions, but he originally wanted to carry out a comprehensive physical transformation, but this result was somewhat unexpected.

"Strength, speed, endurance, well, I want to complete my goal, stop the Nine-Tails, save Jiu Xinai, and change the current system of the clan, these all require strength, I want to become stronger, yes, little baby Ling Yue, start transforming my strength." Ling Fei stopped his pace and said.

"Yes, master, there will be some pain in the process of transformation, please concentrate and be patient. Ling Yue reminded softly. As soon as the words fell, a golden light poured out of the dragon bone ring, and the golden light wrapped the hand, and then upward, the arms, shoulders, until the whole body was shrouded in golden light, Ling Fei's body stood in place, motionless, as if he had been pointed at the acupoint. In the golden light, Ling Fei could be regarded as experiencing the so-called slight pain, how painful it was, the muscles were as fragile as paper, and some of the golden light poured into the body, like a knife cutting the muscles, constantly tearing and recovering, while the bones were repeatedly smashed as if they had been hit by a hammer. At the same time, drops of jet-black juice were discharged from the pores little by little, and there was a faint fishy smell, and the cells of the whole body continued to break and regenerate, more energetic than before, Ling Fei felt that his body was being divided, and the intense pain made him want to pass out several times, but the golden light on his body had a strange effect, which could make Ling Fei keep a clear mind, and he couldn't mix it up.

About thirty minutes later, the golden light flowing through Ling Fei's body gathered in his chest, and the feeling of depression in his chest continued to increase, and after a minute, the golden light seemed to turn into a hand, pushing something out: "Wow????????" Suddenly, Ling Fei bent down and spit out a large pool of purple-black bruises, the blood clot was in the shape of a clot, after vomiting blood, the golden light on Ling Fei's body disappeared, Ling Fei fell to the ground weakly, and the weeds under him were also dyed black by the black juice, and the scene was almost a mess.
