Zhang Wuji took the stone and smashed it hard into the tree.

Bang bang... The sound of smashing the tree was incessant, and the big tree was smashed into a large hole, revealing the heart of the tree inside.

The heart of the tree turned into a pure black object, Zhang Wuji reached out and touched it, and his heart was more certain.

Zhang Wuji's expression was in disbelief.

"How did the heart of the tree turn into charcoal, is it a problem of the type of tree?"

Zhang Wuji picked up the stone on the ground, replaced it with another tree of the same kind as the big tree, and smashed it desperately.

The other tree was not very thick, and it was broken by Zhang Wuji after a few efforts.

Zhang Wuji carefully observed the heart of the tree, it was not charcoal, and there was not even a trace of black.

Lin Jian walked up to Zhang Wuji, patted him lightly on the shoulder, and said indifferently.

"I said that my exercises are countless times stronger than the Jiuyang Divine Skill, now you should believe it, right?

Zhang Wuji was hit and his body was incomplete, and he burned the heart of the big tree into charcoal with a palm in the air, but his appearance did not affect the slightest, subverting his perception of martial arts.

Thinking of what he had just refuted Lin Jian, he suddenly felt ridiculous, and walked to the lake and plunged into the water, continuing to cultivate hard.

Lin Jian slept for a day, and he didn't fall asleep at this time, and lay on the ground leisurely and pointed out Zhang Wuji.

"No wonder your cultivation is so slow, the speed of running the internal force is too slow, increase the speed of the internal force by five times.

When I practiced for the first time, the speed at which the internal forces were activated was dozens of times faster than yours.

Although you don't have my talent, but now that you're familiar with the route of internal force running, it's no problem to increase it by a factor of five. ”

Hearing Lin Jian's words, Zhang Wuji's silver teeth, whose head was stuck in the water, clenched, and the speed of internal force suddenly increased several times, and the pain was like a tear in the tendons and veins.

Under the pain, Zhang Wuji couldn't help but want to slow down the speed of internal force operation, and Lin Jian's voice came.

"The cultivation speed has increased by six times, and it can barely be regarded as passing, so continue to work hard. ”

Zhang Wuji endured the severe pain, unwilling to let Lin Jian look down on him, and put out his thoughts of slowing down his internal strength.

If other people in the rivers and lakes saw this scene, they would definitely be scared to death, this kind of reckless practice, although it will increase the cultivation speed, but it will definitely kill people.

Seven days of kung fu flashed by, Zhang Wuji was worse than death in these seven days, and the suffering he suffered in seven days was even worse than when he was tortured by cold poison for more than ten years.

Several times when he couldn't help but slow down his cultivation speed, Lin Jian beat him violently and coerced him to cultivate.

Zhang Wuji excitedly got out of the water and said to Lin Jiandao.

"Brother Lin, I have already completed the cultivation of eighty pictures, and I am about to cultivate the last one. ”

Although he was tortured by Lin Jian for so many days, Zhang Wuji did not have a trace of hatred for Lin Jian in his heart, thinking that everything Lin Jian did was for his good.

Lin Jian looked at Zhang Wuji, who had a thin face, and couldn't help but sigh that Zhang Wuji's life was big, he couldn't train him to abolish it after practicing like this, if it was an ordinary person, he would have died countless times.

Lin Jian didn't pour cold water on Zhang Wuji this time, and said indifferently.

"It's not bad, seven days to cultivate a broken exercise, it's so-so.

Take a good rest and I'll teach you how to practice the last picture. ”

It was the first time that Zhang Wuji heard the word good from Lin Jian's mouth, and his face showed great satisfaction.

"Thank you, Brother Lin, I will definitely work harder. ”

After speaking, he fell to the ground and fell asleep, in the past seven days, he slept for only one hour every day, and the rest of the time was spent constantly cultivating.

Sometimes when my head was stuck in the water and my neck hung from a tree, I couldn't help but fall asleep, and after falling asleep, I was woken up by severe pain and water, and I continued to cultivate.

When Zhang Wuji opened his eyes again, he happened to see Lin Jian holding a pheasant and eating it.

Lin Jian handed the remaining half of the pheasant to Zhang Wuji.

"You've slept for a day and a night, eat this half of the roast chicken, let's practice the last picture!"

Zhang Wuji took the pheasant that Lin Jian had eaten, and he didn't dislike it, and devoured it.

I haven't eaten for a day and a night, and now I'm really hungry in my stomach,

After Zhang Wuji finished eating, Lin Jian licked the chicken bones, and Zhang Wuji said.

"This last picture doesn't need to be practiced in the trees and under the water, just practice normally. ”

After listening to Lin Jian's words, Zhang Wuji sat on the ground obediently and began to cultivate the last picture.

After practicing a peerless magic skill in seven days, Zhang Wuji no longer had any doubts about Lin Jian.

Even now that Lin Jian said that cutting himself with a knife can increase his cultivation speed, Zhang Wuji will not have a trace of doubt, and he will not hesitate to cut himself with a knife.

Lin Jian gathered his spirit to observe Zhang Wuji's cultivation, and the last picture of his cultivation determined the success or failure of his experiment.

The first time he read the Jiuyang Sutra, Lin Jian became interested in this kung fu and boldly decided to do an experiment.

Nine Yang Divine Skill Ninety-Nine Eighty-One Diagrams, starting from the first diagram, cultivating Yang attribute true qi little by little, cultivating to the fortieth diagram, Yang Qi can not be increased, and only a little true qi left in the body is Yin attribute.

The forty-first diagram is to guide the only remaining bit of yin attribute true qi in the body to merge into the yang attribute true qi, just like a small amount of water sprinkled into a fire, which further promotes the increase of yang qi.

Theoretically, as long as Zhang Wuji cultivates to forty-one figures, most of the cold poison in his body will be disintegrated, and he will not have to worry about his life.

The other forty pictures are to slowly cultivate a trace of pure yin qi, yin and yang attract each other, and a small amount of yin qi continues to fuel the momentum of yang qi until the Jiuyang divine power is completed and becomes a pure yang body.

Lin Jian's experimental idea was to let Zhang Wuji cultivate the Yin Diagram and Yang Diagram separately first, and the Yin and Yang Qi in his body increased at the same time.

Almost a certain amount of Yin and Yang attribute true qi is located in a part of the meridians, and even if there is a conflict, it will only hold on to each other and will not completely explode.

In the end, he cultivated the forty-first diagram to completely detonate the yin and yang qi in his body, Lin Jian just wanted to see what amazing changes would occur when so many yin and yang qi exploded in his body at the same time.

As for letting Zhang Wuji hang on a tree and stick his head in the water to cultivate, it was purely Lin Jian teasing Zhang Wuji.

Although it was to tease Zhang Wuji, these two methods also worked, at least Zhang Wuji would not doze off when he was practicing.

After a while, the sudden change occurred, and the last picture of Zhang Wuji's cultivation of Jiuyang Divine Skill completely detonated an astonishing amount of Yin and Yang Qi in his body.

Zhang Wuji fell to the ground, his body was blue for a while, white for a while, and an extremely painful roar came out of his mouth, and the two qi of yin and yang launched a fierce battle in the meridians in his body, and his whole body seemed to be cut by a thousand knives.

"Brother Lin, I'm so uncomfortable, please kill me!"

Lin Jian grabbed Zhang Wuji's hands to prevent him from committing suicide because he couldn't bear the pain.

"Hold on, you're going to succeed right away, don't give up. ”

Zhang Wuji is a good person, serving Lin Jian to eat and drink every day, Lin Jian is just using him as an experiment, not ready to play with him, ready to rescue him when he is on the verge of death.

As long as Lin Jian didn't want him to die, he couldn't kill himself, and at a critical time, a pill could save him.
