After Hayato Sebun left, only Zhang Xuan, Shizuzu Tanigawa, and Mrs. Shinagawa were left in the laboratory.

"Is this a superhuman potion that can make people very powerful?" Lady Shinagawa asked, pointing to the blue serum, surprised. Between the flickering eyes, there seemed to be some heartbeat.

"That's right, this is it. Tanigawa said.

Zhang Xuan asked, "Mrs. Shinagawa, have you finished your business?"

"I had already called several doctors and nurses yesterday and agreed to meet this afternoon. Mrs. Shinagawa said.

Gu Chuanjing said to Zhang Xuan dissatisfiedly: "My sister is working very seriously. ”

"Xiao Jing, you can't talk to the boss like this. Mrs. Shinagawa reprimanded.

"Sister......

"Obedient. Mrs. Shinagawa said unquestioningly.

Tanigawa snorted dissatisfiedly, plunged into work, ignored Zhang Xuan and his sister, and began to prepare a new superhuman serum.

Yesterday's serums were far from enough.

Mrs. Shinagawa looked at Zhang Xuan and said, "BOSS, I have a request, can you inject me with superhuman potion?"

"What, sister, you want to inject this kind of thing, I don't agree. When Tanigawa Jing heard this, she couldn't be silent anymore and said loudly: "This is just a half-finished product. ”

Zhang Xuan suddenly said, no wonder Mrs. Shinagawa came to this kind of place early this morning, it turned out that she wanted to inject superhuman serum, "Of course you can, as long as you can endure the pain." ”

Although it is a semi-finished product, there actually seem to be no side effects other than once a week injection.

"No, I absolutely disagree!" Tanigawa strongly objected, "Don't forget, this is just a half-finished product, what side effects there are, no one knows, I will never agree with my sister as a test subject." ”

"I can tell you about the side effects. Zhang Xuan said: "Inject once a week, otherwise your physical skills will regress, that's all." ”

"How do you know?"

"Don't forget, who came up with this formula. Zhang Xuan looked at her and said.

"I inject. Mrs. Shinagawa said resolutely.

"I ...... Then I'm going to inject it too. Seeing that he couldn't convince his sister, Tanigawa stomped his foot and said so. She couldn't let her sister suffer alone.

"It's good if you're happy. Zhang Xuan didn't stop it, anyway, the side effects of this superhuman serum are not obvious, even if Tanigawa Jing is injected, there is no harm.

So the two of them were each injected with 100 milliliters of superhuman serum.

In order to prevent the two people from screaming heartbreakingly, they bit their tongues and committed suicide, when the pain attacked, Zhang Xuan tore the sleeves of Mrs. Shinagawa and stuffed them into the mouths of the two women.

Hayato was able to withstand the side effects of the drug because he had already experienced hell, and the pain was nothing to him.

But for two weak women, this pain is undoubtedly very terrible.

If it weren't for Zhang Xuan stuffing his clothes into their mouths, it is estimated that he would have been heart-rending and miserable by now.

Even so, the two women were still rolling on the ground in pain, and in desperation, Zhang Xuan had no choice but to hug the two of them up, hugging them tightly in his arms one by one, not letting them move.

The two women couldn't roll on the ground, so they had to pester Zhang Xuan like octopuses.

Rubbing, rubbing, on Zhang Xuan's body.

To be honest, Zhang Xuan admitted that he was a little excited.

As an otaku and an otaku without a girlfriend, Zhang Xuan admits that he has a longing for women, and he has also thought about what it feels like to hug left and right, but he has never imagined what it is like now.

A surviving person who has a dead husband, and a female doctor who is not yet married.

It all sounds erotic.

As a result, now he is holding himself tightly, constantly rubbing, and they are still a pair of sisters, if this can't make Zhang Xuan excited, then Zhang Xuan will be finished.

Although excited, Zhang Xuan did not make any rude moves, but hugged the two women and remained motionless.

Even though the strength of the two women's struggle is getting stronger and stronger, Zhang Xuan still suppresses the two people steadily.

After yesterday's day's mission, his physical fitness has improved again, and it is not much worse than the superhuman serum injected with the finished product, this kind of person who has been injected with a half-finished product is nothing in his eyes.

It can be crushed with one hand.

Finally, after the effect of the medicine, the two women lay in Zhang Xuan's arms, their clothes were soaked, and they were very sticky.

"Let go of me. Gu Chuanjing spit out the cloth in his mouth and glared at Zhang Xuan hatefully.

Zhang Xuan let go of his hand, Tanigawa Jing pushed him away, feeling the endless strength in his body, and his eyes couldn't help but light up.

Only with the injection of superhuman serum did you know the beauty of this.

The originally thin body is now full of strength. The five fingers clenched into fists, and she could feel the full power, and she wanted to punch the wall, just like Hayato Sebun last night, to see if she could easily smash the wall and blast a hole.

However, after much hesitation, Jing Tanigawa gave up the idea, she was afraid of pain.

After all, the action of force is mutual.

I'm so powerful, what about my sister?

However, when she saw her sister, she couldn't help but stomp her feet and said, "Sister, how long are you going to hold him, but you can't get up." ”

Mrs. Shinagawa found that she was still lying in Zhang Xuan's arms, her face turned red, and she hurriedly pushed Zhang Xuan away and stood up.

She is not the same as Shizune Tanigawa.

She has been married, has children, her body has long been ripe, since her husband died, there is no previous life, just now she was hugged by Zhang Xuan, constantly rubbing, in addition to pain, there is also an unknown pleasure.

So she also felt a little, even after the effect of the medicine, she didn't think of getting up immediately, but lay in Zhang Xuan's arms for a while.

Zhang Xuan pointed to the ground and said to Gu Chuanjing: "Be careful, don't forget that you have been injected with serum." ”

Tanigawa Shizune glanced down and found that where she had stomped her feet, the floor cracked, and cracks spread outward.

"If you use a little force, you can stomp through the ground. Zhang Xuan said. "Gather your strength. ”

Tanigawa was silent.

Zhang Xuan said to Mrs. Shinagawa: "You too, Mrs. Shinagawa, after injecting superhuman serum, your strength has become very strong, restrain yourself when you do things in the future, otherwise you will slap down, and it is very likely that you will beat people to death." ”

Mrs. Shinagawa nodded.

After telling the two people, Zhang Xuan is still a little worried, the two of them are women after all, they have never been exercised, in case something happens, it is difficult to control themselves.

Just, let Hayato Sebun train them too?
