After Zhao Siyu and Zhang Ren knew the skills, they began the training of extreme physical fitness, that is, after their physical fitness reached the limit, they could not stop moving sea rocks, so as to overdraw their physical strength and break the limit. The three-day training made Zhao Siyu and Zhang Ren feel sore after every training, although sometimes Zhao Siyu and Zhang Ren would wonder if this would work, but they still gritted their teeth and persevered.

"Today is the fourth day" Zhang Ren, who had just undergone extreme training, collapsed to the ground, "The training in the past three days is still the same, there is not much change, is this going to work?"

"If you don't think it's okay, you can give up" Zhao Siyu hugged a thousand catties of sea rocks, still trying to move.

"How can this work, I can't fall behind you" Zhang Ren stood up as if he had been beaten with chicken blood, and tried to lift the sea rock again.

At this time, Zhao Siyu had reached the limit of his physical fitness, closed his eyes slightly, forgot the pain of his body, controlled the rhythm of breathing, and let his body get as close to the sea rocks as possible. "It turns out that this is the sea rock, worthy of being mined in the deep sea rock, and today you can still feel the power of the sea from the stone" Zhao Siyu seems to be in the sea, as the sea water shakes and shakes, the whole body is pulled by the power of the sea water, breathing in and out, up and down, slowly and rhythmically, there is no feeling of body soreness at all, every pore of the body seems to be breathing desperately, the breeze is refreshing, through the breath of the whole body, let yourself feel like drifting with the wind, Zhao Siyu is completely immersed in this feeling, suddenly, Zhao Siyu's whole body strength seems to be no longer under his control, and he keeps being pumped outAlthough it was a hot summer, Zhao Siyu still felt the cold of his body deep into the bone marrow, as if his breath would freeze into ice in the next moment, Zhao Siyu wanted to shout, but found that he couldn't open his mouth and wanted to move, but he found that he had been strongly attracted and sucked on the sea rocks, Zhao Siyu tried his best to overcome the fear in his heart, and kept saying' It's okay, it's okay, take a deep breath, take a deep breath' This time seems to be very long, Zhao Siyu feels colder and colder, and feels that the whole body has been out of the control of his brain, it is the rest of his consciousness, and there is no feeling, it may be that the ice is to the extreme, and Zhao Siyu's eyes are also dark,' It's okay, it's okay, take a deep breath, take a deep breath' Zhao Siyu continued to comfort himself, avoiding letting the fear of the unknown overwhelm himself and disrupt his breathing rhythm, suddenly in this dark and boundless darkness, Zhao Siyu saw a little red light, this red light is getting deeper and deeper from himself, as the red light approaches, Zhao Siyu also feels hotter and hotter, as if he is close to the fire, close to the sun, bursts of heat waves, rushing towards him, Zhao Siyu feels that the hair on his body seems to be ignited, eyebrows, eyelashes, hair, and hair seem to be burned, if he just breathes can condense into ice, now, Zhao Siyu feels breathing, the throat is burned, the heart is impatient, it seems that the clothes on the body are superfluous, and even the skin is superfluous, Zhao Siyu tried his best to control his thoughts and kept comforting himself. It's okay, it's okay, take a deep breath, take a deep breath of the hot breath of your breath to make your entire nose, throat, esophagus, and lungs seem to be grilled on a charcoal fire, thick breathing, Zhao Siyu tried his best to restrain himself, in the past three years, Zhao Siyu has experienced things that he experienced too early at his age, his mind is still firm, time passes minute by minute, Zhao Siyu feels like he has experienced hundreds of years, suddenly, the fiery feeling gradually subsided, rapidly compressed in his lower abdomen, and the temperature gradually returned to normal body temperature, the red light that was originally inconspicuous in the dark became a flame, living alone in Zhao Siyu's lower abdomen, it turned out that this was Zhao Siyu's fire of life。

Zhao Siyu finally ended the torment of ice and fire, collapsed to the ground, his clothes were soaked, and he was too tired to speak, and fainted directly.

"Zhao Siyu!" Zhang Ren was on the side, suddenly heard a 'bang', turned his head to see, Zhao Siyu fell to the ground, unconscious, suddenly anxious, kept shouting Zhao Siyu's name, but there was no response, Zhang Ren ignored the exhaustion of his body, and was about to pick up Zhao Siyu and run out.

Suddenly, Zhao Xinlong came to Zhao Siyu's side and said to Zhang Ren, "Don't worry, Xiaoyu is fine, you continue to train here, I will take Xiaoyu back"

It turned out that Zhao Siyu broke through the limit of physical fitness, Zhao Xinlong had been secretly observing, and after ending the library to find books, he still found nothing, although Zhao Xinlong was unwilling, but he was also helpless, and it was three or four days after calculating the time, Zhao Xinlong came to the martial arts training ground, which happened to encounter this scene.

"Xiaoyu, what's wrong," Zhang Ren said worriedly.

"It's okay, it's just that I'm tired from cultivating" Zhao Xinlong replied, "I guess now you already know what I mean by 'Yuan Li', time is running out, you train hard, don't worry about Xiaoyu"

"Yes," Zhang Ren replied.

Zhao Xinlong picked up Zhao Siyu and went to the room where Zhao Siyu was.

After placing Zhao Siyu well, Zhao Xinlong smiled slightly, Good boy, it's really hard for you, just now I watched you break through the limit, experience the test of ice and fire, and I am very worried about you in my heart, fortunately, you are still determined, control the rhythm of your breathing, and finally break through the limit, rest well, wait until you wake up, and then slowly adapt, you should be able to use the Yuan Force in your body, although now your rank is not high, the use of Yuan Force is very limited in time and degree, but this is also a lot of progress, this will also be your advantage, take a good rest"

Seeing Zhao Siyu's snoring, Zhao Xinlong smiled slightly, walked out of the room, and arranged for Wen Bo to prepare some food.

In the face of Zhao Siyu's sudden situation, although Zhang Ren was in it and what Zhao Siyu had experienced, Zhang Ren was sure in his heart that Zhao Siyu must have broken through the limit before himself, Zhang Ren sighed slightly, "It seems that I still haven't worked hard", thinking of this, Zhang Ren was full of fighting spirit and started the training of Haiyan again.

"It's broken, I have to go back quickly to report to the four masters" A black shadow scurried across the martial arts training ground and hurried towards the courtyard where the four masters were.
