Goten noticed that 18 was heavily injured near them.
"Piccolo," Goten called out.
"I got it." Piccolo prepares to go near Andoird 18 to give her Senzu beans.
"Give the two beans to me, and take her back to lookout," Goten said.
"Huh?" Piccolo was confused by Goten's words.
"She probably won't be able to...." As Goten was talking with Piccolo Android 21 rushed towards him to attack him.
".....! Help much in this fight. So it's better for you to take her to Dende so that he could heal her." Goten said as he talked to Piccolo while using instant transmission to rapidly dodge the attacks of 21.
Even after his training, he was still not fast enough to move out of 21's attack no matter how predictable she was as his power was still limited.
So he has to rely on instant transmission that he learned from the Goku of the past.
He also could use Kai kai but instant transmission is less tiring and slightly faster.
"About the senzu bean." Piccolo was unable to hand it to Goten when he was being chased by 21.
If he goes in to give it to Goten he would have been a target for 21.
And he can't just throw it to Goten as the situation that they were in is a little dire.
"Then send 18 back first, give me the beans later," Goten said to Piccolo.
"Ultra God Fist." He said as he leaned to launch an attack at 21.
21 was fast enough to dodge the attack but she couldn't as she didn't see it coming.
It didn't seem to hurt her but the attack was not intended to hurt her.
--------------------------
A few hours ago. While Goten was Training with Goku.
"If it's true that the time that you spend here is the same as the time you were gone then that means you probably won't be able to learn all my techniques," Goku said.
"Even if you are talented, a technique like Kaioken would take weeks if not months to master," Goku said to Goten.
Goten thought about why Yamcha was able to master it very fast until he remembered that he had to spend 1 year in the chamber just to learn that one technique.
"So I think I should teach you about an incomplete technique that is similar to instant transmission," Goku said.
"I know how the concept works but I never fully master it since I don't have much interest in it. Maybe you can complete it and use it instead." Goku said as he looked at Goten.
----------------------------
By combining the ability that was in instant transmission of locking onto the ki signature of one specific person with the ability to absorb ki from his surroundings from the spirit bomb Goten was able to recover some of his ki by absorbing some of 21's ki through physical contact.
Of course, you can do it even without the technique that Goten learned just by having prolonged physical contact but Goten's ability allows him to absorb ki with only a slight touch that doesn't even last a second.
It was difficult to execute as Goten only learned the technique and it would also be hard to use that technique on someone who has impressive ki control unless they specifically allowed you to use it.
And not only that it has a certain limit on how much it can absorb.
21 was not in her right mind as she was consumed by her dark side so it was somewhat successful as Goten recovered some of his powers.
"It seems that it worked," Goten said as he looked at 21.
Then he transformed into his Super Saiyan God Super Saiyan form as he started changing a Final Kamehameha.
----------------------------
"Pink. No, it's the colour of Cherry blossom." Piccolo said as he helped 18 get up while looking at Goten.
"Piccolo. Do you have any Senzu beans left?" 18 Asked Piccolo.
"Huh. I have two left." Piccolo replied as he looked at 18.
He didn't want to lie to her. So he answered truthfully despite himself agreeing with Goten's comment about her not being able to help much against 21.
"Give me one." She asked him.
---------------------------
Goten was able to use Super Saiyan God Super Saiyan for a prolonged amount of time without getting his extra power from that form sealed away immediately.
Because he was able to absorb more energy than he expected from 21.
Now what he needed to do was to destroy the wave machine but he didn't know where she kept it.
So he can only destroy her first before taking care of the machine.
"Final..... Kamehame...." Goten used Final Kamehameha on 21.
However, she countered his attack by launching a dark red orb with a pink aura made of evil ki towards him.
An attack called the Vanishing Ball.
Although Goten recovered some ki from 21 he still isn't strong enough to overwhelm her as getting some of his power back is not the same as getting his full power back.
And he still doesn't think even his full power would be enough.
21 has not only transformed into a stronger form but also absorbed 90% of Super Perfect Cell's powers and Super 13 since he last saw her.
He teleported out of the way using instant transmission before he was hit by her Vashining ball which overwhelmed his Final Kamehameha.
Should I go in for another Ultra God Fist to get more power back from her? Goten thought.
He was starting to run out of the extra ki that he had absorbed from her after using Final Kamehameha.
I need those Senzu beans. Goten thought as he looked at 21.
Then he saw that 18 and Piccolo came towards him and 21.
Goten realized that Piccolo gave a Senzu bean to 18 as he saw 18 recover from her injuries.
It can't be helped. I have to use that. It might be the only thing that I have that might be able to finish her. Goten thought in his mind.
