'Ah ah… Ah…. AHHHHH…. OHHHHHHHH!' Jesse slapped the floor violently while Ada helped him to stretch further on a split. 'It HUUUUUUURTS!'

'Come on, you can do better.' Ada chuckled and pushed Jesse's back closer to the floor. 'Don't give up until your face touches the mat.'

'AHHHHHH MOM!' Jesse's scream became falsetto as his pain intensifies.

Ada smirked at the back of her son and finally let go. Jesse's body swung backwards like a rubber band to 'unstretch' his muscles, shaking them to increase relaxing speed. She enjoyed making her son scream from the pain of stretching, because she knows her son's physique have improved significantly from the training he went through in the special forces but stretching isn't a strong suit for the army men. Even with Jesse's training in gymnastics when he was younger he could do better than most men but muscles are like rubber, if you stretch it often it becomes loose and the muscles form in a high density with lower surface area. If you don't stretch it, it would become tight and clump together.

That is why Jesse looked much leaner than most soldiers but exhibits equal strength which is not due to his dormant viruses. According to him, the dormant viruses would only wake up from the stimulation of high chemical levels such as adrenaline, cytokines, toxins or any other biochemical reactions in the body which trigger the lymphocytes urgently. Chris Redfield looked at least two times bigger than Leon and Jesse but Leon does not have that much raw strength. Jesse however can give pretty strong punches despite having a normal size.

'Hmph, amateur.' Ada teased her son and sat down on a mat. She repeated the stretching routine she just made Jesse do and does it better herself. Doing splits like no one's business. She gave him a coy smile.

Jesse eyed his mother annoyingly and shook his head. 'Show off.'

'Education time.' Ada simply puffed out the words while breathing evenly to aid her progress in stretching. 'What do you think about the usefulness of Chinese martial arts vs CQC?' She said while changing to another position and stretched her leg.

'Chinese martial arts is an older combat method, ancient.' Jesse took a gulp of water and continued. 'It was designed, taught and used in the era where guns weren't invented yet. CQC is more effective in 1v1 with guns and short knives. If the enemy has other weapons there would be variables in the outcome.'

'Not bad.' Ada nodded. 'There's not much theoretical stuffs I can teach you anymore. Let's get right to it.' She stood up and signalled her son to stand up too. 'Chinese martial arts can be used against one person or multiple people. CQC maybe 2 or 3 max.' Ada then circled her son slowly, walking in an arrogant style.

'Whichever part of your body that is having contact with the ground must be strong, firm or at least volatile from the break of contact like the game 'the floor is lava'. The strength of your hits based on your air and how you circulate them in the center of your body using your diaphragm.' Ada said. 'Have you seen Bruce Lee's 1 inch punch?'

'Yes.' Jesse replied. Ada nodded and led him to a sandbag that they have in their home gym. 'Your goal is to calculate how many hits you would take to destroy a sandbag. I was able to do it when I was very young but since I met your father I lost a lot of hate and the drive to destroy most things.' Ada slightly mocked herself.

'Wait, you could break sandbags? How old were you? Is that even possible for a woman your size?'

'Start with punches and then kicks.' She ignored him and instructed.

'1 inch punch?' Jesse asked.

'No, that was just an example of how you should channel your air in your diaphragm to amplify the expulsion power.' Ada corrected him. 'Because when your muscles would follow the air based on how much force you want to have on output. It's too complicated if I have to explain the physics from how the strength can be produced from your legs then to your waist, your shoulders then your arms.'

'Ok.' Jesse took a deep breath and punched the sandbag.

'Don't just breathe literally, feel the air. Everyone's body is different, some people have higher strength when they are exhaling. You have to feel yours.' Ada reminded.

Jesse was quite confused by what she said about feeling the air, and the control of force by adjusting the diaphragm with the air. He adjusted his breath again and punched as hard as he could. With a loud blunt BOOP the sandbag swayed for quite some distance but not enough to break it. Ada gave him a slight disapproving look but not the disappointed look that would upset him.

Ada stopped the sandbag from swinging and adjusted her herself. She didn't take a deep breath but her eyes changed into her cold killer stare, indicating her amount of focus she's putting in. Ada didn't even bend any legs or posing to be ready for combat. She literally aimed her arm and simply BOOP producing almost an equal sound and power that Jesse have just did on the sandbag.

'If you do it correctly, from how hard you punched just now should've broken the sandbag or at least detached its hanging metal chain.' Ada exhaled proudly. 'Don't just rely on the viruses when there's no chemicals to stimulate it. You would be very easy to defeat.'

Jesse was amazed by what he just saw and couldn't close his mouth. 'That's if I run into Ada Wong. What are the chances?'

'You only get to have me make your dinner if you learn something today.' Ada smirked at her 20 year old son. Jesse pouted with irritation and turned to the sandbag again, focusing more this time. He stared blankly at the punching bag in front of him, relaxing all muscles while channelling his focus into his diaphragm control. He punched it forcefully, this time he produced a bigger BOOP and the punching bag swung harder but still not breaking.

'Not bad.' Ada nodded and moved to the punching bag again to keep it static. 'Let's see if this works.' She steadied the sandbag and took a step back. Ada let out a small smirk, her face full of confidence. She turned her body to produce a 360 kick without jumping like the taekwondo method, her supporting leg firmly planted on the floor. Ada's kick produced a super loud BOOP and the metal chain let out a creak which proved the momentum of that kick. Still not enough to break it yet however. She didn't seem to exert too much force into her kick but it still produced such powerful output.

'Close.' Jesse nodded in agreement.

'I should probably visit the gym more often since my body became younger.' She chuckled.

'Yeah, don't spend so much time in the bedroom with dad. Poor guy needs his rest.' Jesse laughed at his mother, earning a light punch from her on his shoulder for saying naughty things to annoy her.

'Your turn.' Ada said to her son.

Jesse copied his mother's moves, performing a 360 kick with the right breathing technique producing a loud BOOP. But this time the metal chain let out a loud creak and the leather of the punching bag began to tear at its top part, leaving the bag half hanging.

'Oh.' Jesse hummed. 'I think I have some progress.' He then simply swung a hook punch at the punching bag. The sandbag suddenly dropped on the floor as the result of its leather tearing from how Ada and her son have punched it so hard.

'Not bad.' Ada gave Jesse a little pat on the shoulder. 'Wanna spar? Loser has to repair the punching bag.'

'Ok.' Jesse nodded and walked over to the sparring ring. Ada entered after him elegantly.

Jesse started with some classic CQC move and Ada easily blocked his attempts to take her throat. With a smooth duck, Ada gave him a left punch just under the ribs which attracts his attention now to block that hand. She kicked one of his knees and utilized the force to take a small leap backwards, increasing their distance. Jesse yelped from the pain of the punch and the kick in his knee. His combat skills have since improved and he quickly charged at her as she leapt backwards.

Ada raised her forearm trying to hit his incoming face as he approached but Jesse skilfully dodged to his left and caught that arm and swung it over his shoulder. He's trying to flip her over but as he was carrying her mid air, she right kneed his back and chocked his neck with another arm. While Jesse's attention turned to the hand that is choking him, he only focused the attacks that are happening at his upper body.

Recognizing her room of opportunity, Ada moved her right leg backwards and hooked Jesse's leg with her left making him lose his balance. With a slight push, she slammed Jesse on the ground.

'You might be strong, but I'm faster.' She gave her son a grin of victory.

Jesse just pouted at his mother and sighed for his loss.

'I'll make your favourite stew.' Ada winked at her son and gave him a wave of bye.
