After playing for a while, a light wind blew and brought a strange floral fragrance into the bedroom.

Xuan Zhu and the other two babies sniffled and their dark eyes widened.

“Wow, what a fragrant smell!”

“It smells a little sweet!”

“Hurry up and see what it is!”

… .

The little girls quickly got up from the recliner and ran out of the bedroom, completely forgetting their previous fatigue.

Soon, they saw a few pots of new flowers in the garden.

The flowers in these flower pots were purple-blue in color. The green leaves were as wide as beds, and the flowers on them were like golden stars.

And the sweet fragrance just now came from these flower pots.

Xuan Zhu’s dark eyes darted around. “Could this be the Star Honey Flower Auntie Tong mentioned?”

She remembered that the last time Tong Shuzhu came to send flowers, she had specifically mentioned that there would be a new variety of flowers.

From the shape of these pots of flowers, the little girl determined that they were the new flower that Tong Shuzhu had mentioned, the Star Honey Flower.

Xuan Han liked flowers and plants the most, so she naturally paid special attention to them. She nodded.

“They’re exactly as Auntie Tong said. They must be Star Honey Flowers!”

Xuan Xi squatted beside the flower pot and pointed at the flowers on it.

“What beautiful flowers. There are nine in this pot alone!”

Xuan Han blinked her beautiful eyes.

“I remember Auntie Tong also said that the Star Honey Flower grows very quickly. It can double in three days at most.”

“Why don’t we count how many flowers there are in total and come back in three days? What do you guys think?”

Xuan Zhu, Xuan Xi, and Xuan You clapped their hands at the same time. “Alright, let’s count together!”

With the arithmetic method Lin Xuan taught them, the little girls quickly counted nine flowers in each basin.

Then, they added all nine pots of flowers together and calculated that there were a total of 81 flowers.

Xuan Zhu said, “There are 81 flowers now. In three days, let’s see if there are 162.”

“Yes!” Xuan Xi nodded.

Xuan Han thought about it and asked, “Then what if three days later, on the sixth day, will it be very troublesome for us to count?”

The little girl thought about it. Although they all knew basic arithmetic, it seemed very troublesome to count so many flowers first and add them up one by one. It was beyond their understanding.

Xuan Zhu thought about it and nodded.

“Xuan Han is right. Since we want to count the Star Honey Flowers, there naturally has to be a better way.”

“I remember that Haoyu’s academy will teach them a way to quickly calculate large numbers. If we use that method, we will definitely be able to count more of the Star Honey Flowers!”

“Yes, yes!” Xuan Xi also remembered that Donghuang Haoyu had once bragged about his arithmetic skills. “Then let’s get Daddy to teach us!”

“Okay!”

Xuan Zhu, Xuan Han, and Xuan You nodded without hesitation.

Furthermore, the little girls felt that Lin Xuan’s method might be better.

After all, he was her most powerful father in the world.

As long as it was a method taught by him, it would definitely be the best method in the world!

“Daddy, Daddy!”

The little girls rushed into the kitchen and hugged Lin Xuan’s thigh at the same time.

“Can you teach us a very powerful arithmetic method?”

Lin Xuan put down the kitchenware and looked at the four chubby faces dotingly. “Of course!”

Xuan Zhu said, “It has to be better than Brother Haoyu’s!”

“When we counted the Star Honey Flowers just now, we realized that it would be very difficult to count in a few days!”

Xuan Xi nodded. “That’s right. It’s a little difficult to calculate with the previous method!”

Xuan Han had a determined expression. “I believe Daddy must have the most powerful method in the world!”

Seeing how expectant and trusting his daughters were, Lin Xuan said confidently,

“Don’t worry, Daddy will definitely let you girls learn the most powerful arithmetic method.”

With the Extreme Holy Book, he knew that the arithmetic standards of this world weren’t advanced.

Donghuang Haoyu’s academy was a top-notch academy in North Mystic Heaven, but its arithmetic standards were actually still very low.

And he had the perfect father program.

Lin Xuan could immediately find a high-level arithmetic method suitable for Xuan Zhu and the others to learn.

It was an arithmetic divine technique that was a must-learn for primary school students…

Nine-nine multiplication method!

Lin Xuan flicked out a few spiritual flames to control the heat of the cooking and carried the four little girls to the bedroom hall.

Then, he took out a piece of paper and wrote the nine-nine multiplication method on it.

Xuan Zhu and the others were stunned. “What is this? It looks so cool!”

Lin Xuan smiled. “This is called the Nine-Nine multiplication method. As long as you remember it, you can calculate many huge amounts of things at once.”

“Nine-nine multiplication method!”

Xuan Zhu and the others’ eyes lit up.

“This must be very, very impressive!”

The little girls only knew that there were incantations for cultivation techniques in the past, but they didn’t expect there to be incantations for arithmetic.

It was obvious that this must be the most powerful arithmetic method in the world!

“Father, teach us quickly!”

Being pestered by the little girls, Lin Xuan felt a strong sense of fatherly love. “Okay, okay, okay. Daddy will teach you girls now!”

“First, one times one equals one means that there’s a flower in a flower pot, so there’s a total of one flower.”

“One times two equals two means there are two flowers in a flower pot, so there are two flowers in total.”

“And so on. ‘Three times three equals nine’ means that there are three flowers in each of the three flower pots. There are nine flowers in total.”

In order to make it easier for the little girls to understand, Lin Xuan specially used flower pots and flowers as examples.

Xuan Zhu’s beautiful eyes darted around and she raised her hand excitedly.

“I understand! We had nine pots of flowers just now. There were nine flowers in each pot. There are eighty one flowers!”

Xuan Xi and Xuan Han nodded. “That’s right. It’s really easy to calculate with this mantra!”

Xuan You bit her finger and studied it for a long time before her eyes suddenly lit up. “Oh ~ So that’s how it is!”

Lin Xuan saw that his daughters understood very quickly and added,

“Multiplication is a simple arithmetic method derived from addition. If you combine it with addition, you can calculate many numbers faster and better!”

“For example, if the eighty-one flowers become twice as many as before, we will split the eighty-one flowers into eighty and one, then multiply them by twice before adding them up. That is…”

Xuan Zhu, Xuan Xi, Xuan Han, and Xuan You thought about it and raised their hands at the same time. “162!”

“By the way, the babies are so smart!”

Lin Xuan laughed happily.

As these cuties grew older, their reaction speed really improved greatly.

Their learning speed was really shocking.

As the father of these smart and cute babies, Lin Xuan was really proud.

“Next, remember the 9-by-9 formula firmly and use it more.”

“Got it! Daddy is so awesome!”

After Lin Xuan finished speaking to the little girls, he asked them to memorize the incantation themselves and then turned to walk to the kitchen.

Ding!

The system’s mechanical voice suddenly sounded.

“You’re quick-witted and allowed your daughters to master the most important arithmetic mantra. Reward: Extreme Sword Technique!”
