Body corruption

It felt as if someone was directly stinging his internal organs with thousand needles. One after another without a delay and each time pain was stronger, then previous one.

It came so suddenly, that he didn't manage to hold back his urge to scream and small "Ugh!" slipped from his whitened lips.

"What is going on?" he said with horrified voice and tried his best to maintain his position. He hoped that with this pain would lessen. But contrary to his thoughts, pain grow bigger and bigger as he unmovingly sat there, till situation got to the point where he thought that he would die from agony.

"This..." In an attempt to find a reason behind this unforgettable pain, he searched into memories of original Timothy Viel and soon found it.

"Gu worm tries to corrupt this body!" He continued as he looked down on his abdomen, from where main stream of pain was coming.

As I stated previously, Gu worm was driving force behind a concept of Gu cultivation. Without it, it was impossible for cultivator to produce a mystic Qi and cultivate in general. In this process body was considering Gu worm as its own part, but that doesn't means that Gu worm was thinking with some way.

Gu worm was a parasite. It didn't had a capacity to think and was just following with its instincts. It would merged with acupoint and helped body with mystic Qi, because it didn't had any better option in this situation. This was for it's survive and as soon as it would have a better alternative, it would move on that, even if this motion would harm its host.

For this reason, cultivators were cautious when they were dealing with their Gu. But there were always times, when cultivators were in difficult situation and couldn't monitor their Gu worm. That was a time, when Gu worm would show it's true color.

Cultivators were calling this process the 'body corruption,' when Gu worm would stopped to provide body with mystic Qi and instead tried to take control on it. It was painful process. One, which could be lasted for several days.

"But... Why now? I already fully possessed this body and have a full control on it. Gu only tries to corrupt host's body if it feels that cultivator's control on his Qi lessened... Lessened!" Realization hit him as he said these words.

He was transmigrator, man from modern earth, whom didn't had any kind of touch with mystic Qi until he possessed this body and despite the fact that he still got original owner's memories and experience, in this field he was still new and control, which he had on the mystic Qi in his body, was probably nonexistent.

"This is bad..." He said, as he fully understood to what kind of grave situation he was in. He was losing control on his body and couldn't use his main power against this invasion.

Worst thing was his cultivation. At the Qi refinement realm, stronger the cultivator was easier was for Gu worm to take control on his body. Gu worms were divided into nine grade. But that doesn't mean that every Gu at the same grade had a similar level of strength. Cultivators at the ninth layer of Qi refinement realm needed much more mystic Qi then cultivators, whom just planted their Gu and were still at the entrance of mystical world of cultivation. But Gu worms, which they planted at that time were still supporting them with usual speed. Which meant that on the different level of cultivation cultivated Gu was at different level. Because there were ten layers on Qi refinement realm humans divided white grade Gu into eleven tiers. From this tiers zero tier was Gu at the infant stage and tenth tier, when it's host was at the peak of Qi refinement realm.

Timothy Viel was at the tenth layer of Qi refinement realm and Ghost Gu in his acupoint had fully matured. In this situation, it would take few hours for this Gu to take full control on his body if original owner was alive and only minutes after his death. Thankfully, before that would happened current Timothy transmigrated and possessed this body.

But now as he was sitting there and gritting his teeth from pain, he was doubting whatever he should be happy or sad about it.

Pain was becoming more and more intense. It felt as if colony of poisonous ants were raging inside his body and trying everything to destroy his acupoints. Changes in his body were becoming visible for necked eyes. Black lines began to appear on his previously pale skin, which now was becoming as white as winter's snow.

From an experiment of original Timothy Viel, body was at its weakest point. His acupoint's were damaged from his second Gu, which he tried to plant in his body. This and limited knowledge of current Timothy Viel were pointing out that, there was practically zero chance, that he would maintain control on his body. But he still wasn't planning to give up on this life without a fight. For him there wasn't anything more important than to be alive and now that god gave him a second chance, he would do everything to not waste this opportunity.

'I still have experience. With some try, I think I can control Qi and resist against this damned thing.' He thought as he tried his best to concentrate on this task and momentarily forget pain, which was burning every part of his body.

He was sitting in meditation position and slowly clothing his eyes. It was hard, but as he focused more, pain which was torturing him for moment ago gradually lessened as he got into state of trance. His thoughts drafted into infinite realm of his unconscious mind as he tried to feel hidden force inside his body, mystic Qi. More he was trying more familiar he was becoming with it. Little by little he could feel his acupoint and how mystic Qi was flowing inside of it. Like a small river. Calmly, without a worry of this world. It was mesmerizing feeling, which gave a peace to his soul. He tried to control it and change its flow. He attempted it number of time and with help of previous holder's experience he managed gasp concept behind of it. It felt as if child was learning to walk as his control over the mystic Qi grew. He needed only a little more time and he would open up the heavenly door of cultivation.

Sadly, before that would happen, his feeling of mystic Qi faded. No, not only his feeling, but mystical Qi itself perished from his body.

As he was sitting there and trying to learn control of his mystic Qi, Gu worm was continuing to corrupt his body. It took some time, but finally Gu managed it and destroyed his acupoints.

Something exploded in his body. Not only once, but nine time. Mental barrier, which he built up in his mind to stop pain, crumbled and fell. As it happened unimaginable pain followed. Pain was so strong this time that he couldn't think about anything else other then it. He opened his eyes and looked at sky with only hope that it wouldn't lasted long. His mind was going blank, at the touch of insanity.

Black vines on his body grow bigger and bigger. They covered his neck and already were touching his eyes. His eyes bloodened and his cheeks fell. He was losing years in the seconds and in just a few minute he looked like an old man who was starving for a few weeks. It would take few second for Gu to take full control on his body and end it all.

But, at the last moment of occupation everything stopped. Gu worm, which was fiercely trying to possesses this body, calmed down and want to its usual state. With this pain faded.

Without any power or willpower Timothy didn't manage to meantime his meditation position and slowly fell on the green grass.
