Seeing that the guys who used to kill kangaroos unscrupulously in the past were all knocked to the ground or grabbed and tied up, the kangaroos all over the land cheered!

Seeing that these kangaroo juniors were a little carried away, the old kangaroo king, who had been commanding the battle with all his might, not only sighed.

Mai Ke was in charge of the overall situation, of course he paid special attention to this kangaroo king, and when he saw it sigh, he immediately knew its intentions, not only said in contrast: "This kangaroo king is a real wise man, I want to go and meet it, will you go?"

"I don't know what you are talking about, I might as well go and see what big shots have been caught!"

"Okay, then you can go and see what to do with these captives, and I'll meet with Kangaroo Wang to finalize future cooperation." ”

So, Mai Ke sent Peter to Sydney, and he found the Kangaroo King and asked him why he was sighing.

The two of them had already known each other just now, and the Kangaroo King had already known that Dao Mai Ke was the biggest head of the Kingdom of Heaven, and the Kingdom of Heaven had come here to change the fate of these kangaroos.

Mai Ke sat on the ground with the kangaroo king, and asked him, "Just now everyone else was celebrating the victory, you seem to be sighing, happy days, what are you sighing for?" Of course, it needs to be used as a medium through the movement of the spirit rhino.

When the Kangaroo King saw Mai Ke mention this problem, he sighed again: "Mai Ke, you don't know what to do! Now my biggest worry is that there are too many rats!"

"What do you mean by that?"

Although the kangaroos do not know the number, the changes around them are still known. Now that I have become their king. I kept walking around, and I found that all the kangaroo families had been increased tenfold before, and this is what it has been like in thirty or forty years.

"The main reason for the large growth of kangaroos is the fear that these British people bring! They hunt kangaroos in large numbers, not counting their own meat, but also processing them into jerky, canned meat and other products, and shipping them elsewhere to sell, and the scale is constantly expanding!

"In order to avoid the genocide of kangaroos, and to cope with the bottomless greed of the British, the kangaroos had to fight with fertility enhancements.

"Maybe you don't know what to say. Mai Ke. Do you know the two characteristics of kangaroos in terms of childbearing?"

"I really don't know what to do! Come and listen!" First, I am really curious, and second, I see that this old kangaroo king is like an old man, there is no end to it, Mai Ke strives to be a good listener who knows how to cooperate with Lu Dao. Therefore, he urged with interest.

"First. Kangaroos have two internal nursery pouches. There can be two wallabies at a time,......"

"What is an internal baby pouch?" Mai Ke didn't understand the term.

"Ahem! It's the one that gave birth to the wallaby! I also listened to those Brits talk and make analogies, and I learned the name of Lu Dao. Kangaroo King explained for a long time. Only then did I know that it was talking about the uterus of a kangaroo.

Two wombs? Mai Ke really doesn't know the way, not only does he not know the way, but he also doesn't believe it!

"Okay, it's the womb!" Kangaroo King learned quite quickly, and immediately followed Mai Ke Mai Ke to change his words. "As for the two wombs, if they are pregnant at the same time, it is equivalent to multiple births, which is not surprising, but the two wombs of kangaroos are different, and they are pregnant in turn!

"They wait for one to be produced, and then the second one starts, taking turns to take over the baton!

"Moreover, although kangaroos can have multiple births, only two kangaroos survive each time, no more, no less, do you know what Lu Dao is for?"

"I don't know what to do!" Mai Ke replied honestly.

"This answer is simple! Because only the kangaroo mother has only two teats, and each little kangaroo is assigned one, and the special milk is dedicated, that is, no more and no less! Although the kangaroo mother has four breasts, only two are for the young to eat, and the excess ones cannot survive, so the kangaroo gradually adapts to this state, and many times, only two litters are born. ”

"I see, teachable!"

"In addition to the two wombs, there is also the peculiarity that the mother kangaroo has an extracorporeal uterus!" said the kangaroo king, seemingly proud that he had found a new application for the terminology that Mai Ke had just taught him.

The extracorporeal uterus Mai Ke was stunned again, what was that? It was immediately reflected, it must be the big bag of the kangaroo, that is, the nursery bag.

"Well, that's a good statement! However, for the sake of communication, you should use a baby pouch!" Mai Ke suggested, and be careful not to discourage it from accepting new things.

"Okay, just the baby bag. This pouch is very important for the cubs! After the wallabies are born, they are only the size of peanuts and cannot survive on their own, and this pouch is equivalent to a semi-open womb, and all the needs of the wallaby are supplied through the special nipples assigned to it, which is its lifeline that cannot be left for a while. You now know better why you have a cub and a nipple. ”

"Understood, it's amazing!"

"I'll say a few more words about the baby pouch, that bag is also wonderful, and it seems to be infinitely expandable. The peanut-like wallabies live comfortably in it, and when they reach hundreds of kilograms, they are still inside, and most of the time, they are four rats in the same bag!

"Like human children who are constantly breastfeeding, all kangaroos continue to rely on their mother's milk as a staple food or supplement for a long period of time.

"Do you remember the four teats, which were given low-fat milk to the young, and the other two, which were provided with high-fat milk, were given to the juvenile kangaroos who were still growing!"

Mai Ke suddenly realized: "No wonder they can four rats in the same bag, it turns out that they have their own special nipples! I'm still worried that they are competing and starving those two wallabies!"

"Exactly! Mai Ke, you are the smartest kangaroo I have ever met...... Ah, no, the smartest man, before I can talk about it, you know it! Oh, hehehehe......"

Mai Ke didn't know whether to cry or change his happiness, so he had to accept it and go back modestly, and then said, "This is very good, why are you still worried and sighing?"

"I heard about your policy, never kill kangaroos again, if it continues to multiply like this in the future, doubling in five years is definitely the lowest estimate, I am afraid that the rats are overcrowded! Not only will these grasses not be enough, but they will also destroy the foundation, reduce the yield a lot, and there will be new disasters. ”

Mai Ke thought about it, there is really this problem!

However, since they are worried that they will multiply in large numbers if they are extinct, they will definitely control their reproduction without this threat, and the grass that the old kangaroo king is worried about does not seem to be a concern, and they will not eat the fruits of the four seasons without grass?

Not to mention that these kangaroos are increasing tenfold and hundredfold, and there will be no shortage of supply, so the worry of the old kangaroo king will not appear in one hundred and eighty years!

Therefore, Mai Ke told the old kangaroo prince about this consideration, and with the current prestige of Mai Ke in all the kangaroo groups, the kangaroo king believes 100% of Mai Ke's words!

The Kangaroo King waited for Mai Ke to finish speaking, and the dark clouds in the sky blew away, whether it was on his face or in his heart, it seemed that it was hundreds of years old, and it seemed to be gone, and one turned its head out of the dragon and went to participate in the carnival of those young kangaroos.
