Since he is fateful, Ma Qiang can't help but worry about himself.

When I ate that strange fruit that day, my body changed.

So.. What has changed in my body now?

There are no testing instruments these days, so it's really a guess...

I can only say that for now, there is still nothing negative...

Wait a minute! There is a situation!

Ma Qiang looked back at Qingcheng, he and Qingcheng have been married for a long time, and even Qingcheng has not been able to get pregnant, and he also pulled Lime up, but until now, Ma Qiang still has not had a son and a half daughter.

This matter has even become a major concern for many people in the Zhenbei Army.

In later generations, the absence of children will not have any impact on the regime, but in this era, if there are no children to inherit political power, then prepare for chaos in the world.

Of course, this child refers to the patriarchal, it doesn't matter if you are biological or not, or even whether you are related by blood or not, such as Chai Rong, who was later accepted as a righteous son by his uncle Guo Wei, and finally inherited Guo Wei's political legacy and ascended the throne as emperor.

Ma Qiang also knows this truth, but he feels that he is still young and in a hurry, otherwise he will have back pain, so he doesn't pay much attention to it, but now that he has eaten the radiation fruit, he can't help but care.

When you go back, you must take a microscope and look at your own tadpoles....

Ma Qiang squatted down and asked in a low voice to Sister Tiger.

"Sister Tiger, were the loess and white smoke born before or after you and Brother Tiger ate that fruit?"

Sister Tiger glanced at Ma Qiang suspiciously, and roared in a low voice.

"After that, I found this place first, and then he came and wanted to rob it, and I beat him, and I thought it was not good to have a male tiger at home, so I accepted it as my male tiger."

....

Sister Tiger is mighty!

After doing it for a long time, Brother Tiger is still a son-in-law.

Brother Tiger, you're quite fashionable~

"Sister Tiger, I've been married for a few years, and I have never had offspring... Does it have something to do with this fruit? ”

Ma Qiang said and looked at the small tree growing on the cliff.

The little tree hadn't grown much over the years, and it still had a few fruits hanging on it.

Roar~~ "I'm just a tiger, how can I know about you humans!" ”

....

Meow, what you say makes sense!

Ma Qiang looked at the small tree, and always felt that he had no descendants to have anything to do with the tree, but he didn't know how to solve it.

Wait a minute!

That's not right!

Why are Sister Tiger and Brother Tiger still only two offspring of loess and white smoke after so many years?

Can't the animal kingdom also start to engage in family planning, only need a second child, right?

"Sister Tiger, didn't you regenerate later?"

Roar~~ "I don't want to, it hurts..."

Oh, that's right.

You tigers didn't have a caesarean section either.

"That's Brother Tiger is good, many of our humans outside can't do this."

Sister Tiger showed a smiling expression and looked at Brother Hu, who was hiding on the side and playing with white smoke and loess, and roared.

"It thought that it went out to find a few tigresses, but none of them gave birth, and in the end it had to come back, after all, there was still fruit here."

？？？

Ma Qiang looked at the fruit on the tree and thought of a possibility.

Could it be that a creature that eats the fruit can only have offspring with another creature that eats the fruit?

The only scientific explanation for such a thing is... After eating the fruit, the organisms have mutated genes, which eventually makes it difficult to have children with other humans who have not mutated, or they are unable to have children at all, and reproductive isolation occurs.

What kind of fruit is this TMD?

Ma Qiang looked at the small tree, and really had an urge to move back to the Academy of Life Sciences under the Chinese Academy of Sciences.

It's a pity that there are no life sciences schools now, more... It's impossible to move this thing away under the nose of Brother Tiger and Sister Tiger.

Then if you want offspring, you want to let oranges and limes eat this thing?

Sister Tiger squinted her eyes and lay on the ground and began to nap, after all, she was still a big cat.

"Sister Tiger... Can you give me a few more fruits? ”

Sister Tiger opened her eyes slightly and said, "You have helped me raise children for nine years, so take nine, and I want to give Bai Yan another one to eat."

Remember, eat one after each flower, and don't eat too much. ”

"And what if you eat too much?"

Ma Qiang asked curiously, after all, if you say this, you must have eaten more.

Sister Tiger yawned and said, "Anyway, a wolf that ate two last time died in the end." ”

Ma Qiang had a picture of Sister Tiger forcibly feeding a gray wolf to eat fruit.

Tut-tut, I can't bear to look at it.

It's really not the animal world.

Ma Qiang watched Sister Tiger leap up the cliff and slap the fruit to the ground, while Brother Tiger stuck out his tongue on the side, as if he was scolding something.

Behind this cliff... It's probably all uranium ore.

When Sister Tiger lays down ten fruits, there are only two or three left on this fruit tree.

This time, it looks like he's here to rob him.

Those who eat this fruit will have offspring among themselves?

Ma Qiang picked up the fruits one by one and put them in the small pocket he carried with him, which originally contained some dry food.

The green orange stepped forward and picked up one, smelled it, only felt the aroma, and wanted to eat the fruit immediately.

"Little Pony, what is this? It looks delicious, can I eat one? ”

Ma Qiang opened his mouth, he wanted this fruit, so naturally he had a child with the Qingcheng sisters... But whether it will really be safe to eat this fruit in his stomach, he is not sure.

He was still hesitating, Bai Yan stuck out his tongue first, and instantly rolled a fruit into his stomach, and Ma Qiang didn't even have a chance to stop it.

"Oops! White smoke, don't eat it again, your mother said that you can only eat one fruit a year! ”

"Can only eat one a year? Little Pony, what do you want to do with so much? ”

....

Oh yes...

Ma Qiang looked at a bag of fruits, and only felt a black line on his head.

I'm two women now, green orange and lime, and Diao Chan hasn't eaten it yet, okay, even if Diao Chan is counted, isn't this only three...

The other six... What to do?

"Sister Tiger... Is it still useful to dry this fruit? ”

Sister Tiger glanced at Ma Qiang, is it good that she is a tiger, and she also dried the fruit, why don't you ask me if I will make wine with the monkey?

Not to mention, Sister Tiger's family has eaten so many strange fruits, and their IQ is indeed high and scary, at least, Ma Qiang has not seen much animals roll their eyes except for huskies.

And the husky rolls its eyes, it's called two, and it's not called smart.

Suddenly, Bai Yan roared, only to see it keep slapping its head, the bulges on both sides of its body became bigger, its eyes were blood-red, its legs were kicking, flying sand and stones, Qingcheng saw this, and immediately took out the dagger from his arms, jumped in front of Ma Qiang, and protected Ma Qiang behind.

Although he grew up watching Bai Yan grow up, Bai Yan is a tiger after all, this tiger is crazy, who knows what he can do.
