I Luke reincarnated in this cultivation world 40 years back and joined a dual cultivation sect called yin-yang sect at the age of 10 , it is one of the top 5 cultivation sects in the cultivation world and is known for its unique way of cultivation.

Though it's a dual cultivation sect it isn't mandatory to have sex to cultivate. men practice Yang cultivation pathway and the women the Yin pathway. One can continue solo cultivate only up to a certain limit, not because it harms the body but due to resultant dual cultivation which happens after a period of accumulation would end up in a nuclear fission powerful enough to kill them due to dual cultivation

Dual cultivation uses the principles of nuclear physics at a nano level to amplify the energy while dual cultivation which happens as a result of clash between Yin and Yang energy.

So cultivators joining this sect require their body to reach at least the level of Qi body refinement stage before they can engage in dual cultivation, so that their body can handle the explosive energy without them dying.

So it took me 10 years to reach the required stage and to finally find a partner to cultivate.

Fucking bastards they should have put it into the recruitment notice, they didn't even allow for a causal fuck during those 10 years.

I found my partner Ming Ling while fighting against demons, she was at golden core stage at the time and was fighting fiercely on the front lines against a undead, but I wasn't strong enough to support her from the front lines, I was fucking pissed at those undead which attacks relentlessly at night times and the only way that was available at the time was to either burn the undead energy using the Yang energy or absorb the undead's Yin energy to prevent them from regenerating

Burning the undead didn't have any side effect, but absorbing the yin energy caused the female cultivator whi absorb them to become horny, the more you absorb the more horny you become, which wasn't a big deal as it was solved by dual cultivation.

It was infact beneficial for our sect as it improved our cultivation strength while fighting, to be specific it improved the cultivation strength of dual cultivating couple, Single Male Yang cultivators were left to do Clean duties each morning after fight while those couples dual cultivate in morning to improve the strength, while single Female Cultivators were nearly absent as nearly all of them had already choosen their partners, few of the single bitches ended up becoming second wife of other male cultivators as the remaining men weren't handsome enough for them.

Despite practicing cultivation which improved physique which also improves our looks, my average face became okay looking face, it was difficult to beat those handsome looking retards

After the first day of the war with undead, only 50 men were alone cleaning up the battlefield, while 20 of the Women were under closed cultivation alone , few of them were widows, few of them waiting for their right men, few of them totally detest men and end up having lesbian sex to satisfy their lust

The sect surprisingly allows these kinds of couples as only strength speaks in the cultivation world, these lesbian couples ended up splitting the men's cock who tried to force upon them

being from the modern world started selling them strap-ons and dildos to these women and now is one of the biggest sex toy supplier in the cultivation world

Though I wanted to watch them using it, I only got a first towards my face each time I put forward the request

And Sales of these sex toys during that time wasn't that much and required me to go to each women's cultivation room and explain about it before selling it to them

Ming ling was a widow who had lost her husband long back and was one of the peerless beauty of our sect, though I wanted to do sell it to her, I didn't approach her as she was one whole realm higher than me and might kill me easily in one slap, so I only approached those within same realm

While I was thinking about approaching the lesbian couple for selling the next toy I was caught by Ming Ling who beat me black and blue and stopped me from selling sex toys and confesticated it.

These undead waves usually lasts for a month and is a free cultivation boost to our sect

During the last day of the battle while everyone was focusing on defeating the undead, no one noticed a vibrator falling down Ming Ling's leg other than me, While Ming Ling tried to take it back immediately ended up looking at me who was looking at her.

And from there one thing led to another and we ended up marrying next year and had a happy life for 20 years

Till this battle,

It was the same old undead, I broke it easily while my wife Ming Ling was the Yin energy, with our synergy we ended up becoming top 3 Cultivators of our sect, leaving only sect master above us, we both were already at nascent soul stage, which is two realms above Qi body refinement stage

As we were clearing the battlefield an unexpected change occurred and all the yin energy suddenly converged at the centre of the battlefield forming a tornado

And from within with a huge bone dragon emerged and blew blue flames splitting the battlefield

" fuck retreat!! "

" Retreat! "

Commands were issued to retreat as these undead would disappear in daylight and there was no need to throw away our life without any preparation

As we were trying to retreat, the bone dragon caught my wife with its claws, I couldn't run away!

I violently hit the dragon with my sword, which was only able to cause a few scratches on its bone

Left with no other choice I used my last trump card, I absorbed the Yin energy to catalyze the fission reaction and proceeded towards fusion reaction to improve my realm twice and burnt the dragon away !
