"Is it true?" Zhang Yan considered it secretly.

Zhang Yan sat cross-legged again. This time he was prepared well for cultivating Asura Change. He absorbed the surrounding elemental gas fast in accordance with the technique on Asura Change, however, nothing changed. Zhang Yan understood how amazing the Asura Change was. If the natural gas he had absorbed before was like a brook, the natural gas that the Asura Change engulfed was like an ocean. They were totally different.

When Zhang Yan cultivated before, the absorbed natural gas would be transformed into spiritual energy in his Dantian, then be absorbed by some strange object. No matter how hard Zhang Yan had cultivated, his spiritual energy had been drawn away, which had caused him not to be a Xiantian warrior.

A Xiantian warrior, after breaking through to the ninth level of Body Refining, can absorb natural gas by training techniques and formed spiritual energy cyclone in Dantian. While being a Xiantian warrior, a cultivator would undergo a complete change after which his or her strength would be improved and lifespan be prolonged.

An ordinary warrior had a lifespan of one hundred years while a Xiantian warrior had a lifespan of three hundred years. Most mortals cultivated for enjoying a longer life. Higher cultivation, longer lifespan.

Zhang Yan had no idea what had absorbed spiritual energy from his Dantian before. During the past three years, his experience told him that it was spiritual root in his Knowledge Ocean.

Two elements were critical for warrior to cultivate, the one was physique and the other one was spiritual root. The two elements were both divided into six stages high to low, Ordinary Stage, Houtian Stage, Xiantian Stage, Imperial Stage, Saint Stage and Immortal Stage.

Physique, as the supporter of life, was the most essential element to a warrior. The quality of physique had great influence on a warrior. People in Ordinary Stage of physique had difficulty cultivating due to their inborn blocked meridian. They can hardly break through to Xiantian Stage.

Most people were considered to be in Ordinary Stage in terms of physique, for whom the ninth level of Body Refining was the highest level.

However, people of Xiantian physique owned high quality meridian, which helped a warrior cultivate more easily than people in Ordinary Stage. Zhang Yan was a warrior of Xiantian physique, so he could improve a lot in Body Refining stage. When he was eight, he began to train in Body Refining, and he broke through to the ninth level when he was thirteen.

Spiritual root represented perception and natural gift of a warrior. With a higher spiritual root, a warrior can cultivate techniques and improve martial skills faster. When cultivating the same technique, people of spiritual root in Ordinary Stage needed three months to gain initiations while people in Saint Stage can master the introductory part by reading the technique once. Which level was Zhang Yan's spiritual root in? He didn't know that. What he only knew was that he had mastered all skills in one hour when his grandpa taught him the technique of Body Refining.

Surprisingly, his spiritual root was different from that of others. Generally, spiritual root was preordained and unchangeable. However, his spiritual root increased bit by bit. Though its increasing pace was slow, Zhang Yan felt its change obviously. When his spiritual root grew, it absorbed spiritual energy from him. Zhang Yan produced a little spiritual energy in cultivation, thus nearly no remained after being took by spiritual root. That's why Zhang Yan failed to break through to Xiantian.

It was different these days. Cultivating Asura Change produced spiritual energy several times more than that in cultivating other techniques before. Besides being absorbed by spiritual root, spiritual energy remained a lot which gathered together in his Dantian and then diffused within his body. Such diffusion could be controlled by himself because it spread for curing his injuries.

Half hour later, he was cured. Then he tried to cultivate Asura Change with all his strength. The natural gas surrounding him flowed into his body wildly through his nose and mouth. Zhang Yan accepted all the gases insatiably.

Spiritual energy in his Dantian increased from none to overabundance. When excessive spiritual energy was about to make Dantian burst, Zhang Yan collected all spiritual energy together bit by bit by cultivating Asura Change and then condensed them into a cyclone circling fast in Dantian.

The first cyclone appeared, which represented that Zhang Yan broke through Body Refining Level to Xiantian Stage and became a real Xiantian warrior.

After the first cyclone was produced, Zhang Yan continued cultivating. Lots of natural gases entered his body and then were transformed into spiritual energy in his Dantian. Immediately, another cyclone appeared in his Dantian and finally turned into one of the same size with the first. It showed that Zhang Yan achieved the second level of Xiantian.

The moon was like a silver dish and the sky was studded with twinkling stars.

Unconsciously, he had cultivated for two hours. When his cultivation was stable in the second level of Xiantian, he met the bottleneck. Based on that, more cultivation made no breakthrough.

"Ah!"

Zhang Yan opened his eyes and a light flashed in his eyes. Limitless energy rushed out from his Dantian and spread in his whole body. Zhang Yan clenched his fists and enjoyed the feeling of strong power. He cannot help crying into the air.

Looking into the Pingyuan City, Zhang Yan said coldly, "You will see, Ma Yong, I'll kill you!"

He thought his body was sticky and smelled a foul smell. He looked down and found that his whole body was covered by sticky mucus. Zhang Yan understood that it was a feedback of spiritual energy.

It happened when cultivating Asura Change for the first time that such training would help cultivator make a through change in order to discharge impurities, improve health and strengthen physique. In other words, cultivator made great advances based on Xiantian physique. The above situation would appear again when cultivating the second change of Asura Change until impurities were discharged fully and achieved the Immortal physique. The process was very slow. What's more, the cultivation of the second change of Asura Change required one object, Burning Sun Herb, or all was idle dream.

However, it was too far for Zhang Yan who was in the second level of Xiantian. It was urgent for him to find a river and wash the impurities off. It was smelly!

He found a river and jumped into it. He was considering what to do in the future while he was washing himself. Though he carried blood feud, he learned a lesson before. He would never be rash as before.

After analyzing the circumstance carefully, he decided to let hatred go temporarily. He desired to run to Family Ma and kill Ma Yong, but he couldn't defeat Family Ma currently. At present, he needed to find a patron and join a school. He would cultivate hard, and return with enough strength to take revenge on Family Ma. Revenge would never be late.

After making up his mind, Zhang Yan got up from the river and found that his scars all disappeared. His body had been covered by scars because of hunting. At this time, his skin was bronze and he looked so energetic.

He got dressed, then walked to deep Qingyuan Mountains at which the holy martial land "Qingyuan School" was located.
