n“I didn’t expect these two cuties to drool so much.”

nLin Xuan gently pressed Xuan Xi and Xuan You’s lips.

nThe two little girls immediately shut their mouths.

nBut after a while, they opened their mouths slightly and saliva flowed down from the corners of their mouths.

nLin Xuan smiled helplessly and could only send out a strand of spiritual power to dry the clothes on his chest.

nHowever, the little girls’ saliva quickly wet his chest again.

n“Forget it, forget it. Let them be.”

nLin Xuan couldn’t be bothered to do anything else. Many children liked to sleep on their stomaches when they were young.

nIf the lay down, it would be very easy for them to drool if their mouths were open.

nLin Xuan couldn’t bear to disturb his daughters’ sleep, so he ignored them.

nJust like that, around dawn, the little girls slowly woke up.

n“Huh?”

n“It’s so wet!”

nXuan Xi and Xuan You felt that their chins were wet, and their father’s chest was also wet.

nLin Xuan smiled. “This is all drool.”

n“So much?” Xuan Xi and Xuan You were shocked.

nThe two little girls hurriedly went forward to blow at Lin Xuan while saying anxiously,

n“With so much saliva on Daddy, what if Daddy catches a cold?”

nAlthough the bedroom was very warm, the little girls remembered their mother saying that they could not get wet, or they would easily catch a cold.

nHearing them say this, Xuan Zhu and Xuan Han hurriedly went forward.

nThe four little girls all looked like they were working hard as they pouted and blew at Lin Xuan.

nWhen he saw their cute and filial expressions, the fatherly love in Lin Xuan’s heart instantly erupted.

n“Babies, don’t worry. Daddy won’t catch a cold!”

nHe casually sent out a strand of spiritual power and blew his clothes dry.

n“Wow! How awesome!”

nXuan Zhu and the others revealed shocked expressions.

nEven if they blew for so long, it could not be compared to a wave of their father’s hand.

nTheir father was really omnipotent!

n“Alright, since you’re awake, let’s get up!”

nLin Xuan then carried his four daughters dotingly and brought them down the bed to wash up.

nAfter breakfast,

nXuan You carried a small wooden box out of her room with an excited expression.

n“Sisters, come take a look!”

nXuan Zhu, Xuan Xi, and Xuan Han hurriedly went forward to take a look. “Wow, there are so many snake eggs!”

nXuan You said proudly, “That’s right. My Nine Scaled Python is good at laying snake eggs!”

n“This time, I will let it wait until the snake babies are born before sending all the snake babies to the forest.”

nXuan Zhu frowned and said, “There seem to be especially many snake eggs this time. With so many snake babies, isn’t it a little too scary?”

nXuan Xi and Xuan Han nodded.

nThe Nine Scaled Python was originally a very ferocious demon beast. Xuan You even wanted to throw its snake babies everywhere. It was really scary!

n“Is it a lot?” Xuan You tilted her head and looked at the wooden box in her hand. “I’ve never counted how many snake eggs the Nine Scaled Python can produce!”

n“Why don’t we count it?!” Xuan Han said.

nXuan Zhu and Xuan Xi nodded as well. After Xuan You said that, they also wanted to know how many snake eggs the Nine Scaled Python had given birth to.

nThen, the little girls calculated the number of snake eggs according to the counting method taught by Grand Tutor Yang Wencheng.

n“One, two, three, four… ten!”

nThe little girls were in a dilemma when they counted to ten. What should they count with after ten?

nXuan Zhu thought about it and said, “Each of us should count by tens. A few tens are dozens!”

n“That’s right, that’s right!” Xuan Xi and the others felt that their sister was really smart.

nBecause ten was a round number, the little girls quickly counted 80.

nHowever, they really could not calculate after that.

nXuan Zhu and Xuan Xi both counted eight, and then Xuan Han and Xuan You counted nine.

nThey could not add it up no matter what.

nAfter a few tries, the little girls looked dejected.

nUnexpectedly, at the last moment, they still failed to count how many snake eggs there were.

nIn the end, they could only ask their omnipotent father for help.

n“Father, what should we do to count the last few snake eggs?”

nXuan Zhu and the others hugged Lin Xuan’s legs and widened their black eyes.

n“Daddy will think of a way for you guys!”

nLin Xuan rubbed their little heads dotingly and searched through the perfect father program at the same time.

nThrough the tutorial, he learned that when children were three or four years old, the most common way to count was to count fingers.

nFurthermore, the most common calculation method was to use one’s fingers to add and subtract.

nHowever, this method had a huge flaw. Not only was it a waste of time, but it was also difficult to calculate if it exceeded ten.

nSo Lin Xuan chose a very convenient and easy method to understand in the tutorial.

nFurthermore, he had deliberately observed his daughters’ arithmetic just now.

nSo now, he could teach them this method according to their aptitude.

nHearing Lin Xuan’s confident tone, Xuan Zhu and the others nodded happily. Their father indeed had a way!

nLin Xuan then said, “Babies, you know all the calculations within ten and the integers of ten and hundred, right?”

n“Yes! The grand tutor taught us!” The little girls immediately nodded.

n“Okay!”

nLin Xuan nodded. Actually, he realized that his precious daughters’ arithmetic skills were already very impressive.

nEspecially Xuan Zhu. Even she could think of a way to use dozens for calculations. She was quite impressive.

n“Then what Daddy wants to teach you guys now is the Ten Dozen Method.”

nThe little girls’ eyes lit up when they heard that. This method sounded so novel!

nLin Xuan continued, “The so-called ten methods are to turn any number into the ten you’re most familiar with.”

n“For example, eight and nine. Because nine plus one is ten, eight is divided into one and seven.”

n“Nine plus one is ten. Ten plus the remaining seven makes seventeen.”

nXuan Zhu and the others frowned and thought for a while.

nThen, their eyes lit up.

n“Oh ~ So it can be counted like this!”

n“I understand. This way, no matter what number we encounter, we can divide it by ten!”

n“That’s right. We were left with two eights and two nines just now, so we can make out three tenes and one four.”

n“That’s 34!”

nSeeing that his daughters understood immediately, Lin Xuan was filled with a sense of achievement.

nHe had seen many parents in his previous life who were overwhelmed by their children’s mathematics education.

nBut now, as a father, he had the perfect father program and could easily teach the children powerful arithmetic methods.

nThis kind of life as a homemaker was really relaxing and satisfying!

nIn order to let his daughters completely master the basic arithmetic, Lin Xuan added,

n“100 plus ten is 110, plus 20 is 120. Just read the single digits behind.”

nXuan Zhu and the others nodded at the same time. “Got it, so there are a total of 114 snake

neggs!”

n“How smart!” Lin Xuan was extremely happy and kissed each of their little faces.

nDing!

nAt this moment, the system’s mechanical voice suddenly sounded.

n“Your fatherly love is overflowing. You taught your daughters the trick to arithmetic. Reward: Great Saint Realm cultivation!”
