Zhu Hong took the math problems written by Master and left the room.

Lu Zhou suddenly remembered where Zhu Honggong got the information from Si Wuya. How could Si Wuya easily let Zhu Honggong get the information away?

Rongxi and Rongbei are so big, where can I find memory crystals?

Lu Zhou returned to the living room and sat cross-legged on the futon.

I carefully sorted through Ji Tiandao's memory again, trying to get information about the memory crystal, but unfortunately, I found nothing in the end.

"What is it that is sealed? The secret of Ji Tiandao's attack on Jiuye, or is it something else?"

When Lu Zhou was fine, he summarized several aspects related to memory loss: First, Ji Tiandao's system, which can be inferred from the seamless connection of the merit system at the beginning of time travel; second, the memory of the Heavenly Book, the Queen Mother in the palace used the Heavenly Book

Treat the disease and give him this reminder; third, the information that Ji Tiandao wanted to kill Yu Shangrong, which Yu Shangrong said personally when he was in Yunzhao'an; fourth, Ji Tiandao's memory before his death.

The last point is open to discussion. Perhaps when a person is dying, his brain will lose his thinking and thus his memory. Or he may suffer from Alzheimer's disease. This is possible.

If you want to find the memory crystal, you really have to train Si Wuya well.

Thinking of this, Lu Zhou shook his head.

Putting aside distracting thoughts, Lu Zhou picked up the last heavenly book and opened it——

"synthesis."

[Ding, a new heavenly book has been synthesized and opened. Do you want to understand it? 】

"Enlightenment."

As Lu Zhou recited silently, the fourth complete version of the Book of Heaven opened and turned into dots of starlight, blending into his body. A faint blue brilliance poured into his mind.

Suddenly I felt a cool feeling, filling my mind, filling my eight meridians... filling all my senses.

Lu Zhou was confused.

After this opening of the Heavenly Book and enlightenment, it was completely different from the three previous openings of the Heavenly Book.

He clearly felt that his body's eight meridians and functions seemed to be nourished.

Open the system interface and take a look——

Remaining life: 12754 days.

Three thousand days added?

Equivalent to the lifespan provided by ten reversal cards.

This reward is not bad.

This is the first time Lu Zhou has obtained life span from a non-prop card function... This provides Lu Zhou with a very valuable clue: even people with an end of life can obtain life span. In other words, the truth of a thousand-year life span

, can be broken.

Lu Zhou closed the system interface and began to comprehend the new book of heaven.

According to the previous rules, a heavenly book is opened and a heavenly book magical power is unlocked. So... what will it be this time?

…

Zhu Hong took the rice paper together and ran towards the back mountain with a bang.

Soon, we came to Siguo Cave.

"Seventh Senior Brother..."

Si Wuya sat in the Cave of Thoughts, closing his eyes and concentrating. He didn't think about the questions left by his master at all, and said, "What's the matter?"

"Master gave it to you." Zhu Hong came to the cave and handed the rice paper to Si Wuya.

Si Wuya took the rice paper and quickly browsed:

"There are pheasants and rabbits in a cage today. There are thirty-five heads on top and ninety-four legs on the bottom. How many pheasants and rabbits are there?"

Zhu Honggong scratched his head and said: "Seventh Senior Brother, what is written on it?"

Si Wuya ignored him.

His mind and attention were immediately captured by this question, and he quickly fell into it.

He thought quickly in his mind.

Zhu Hong saw that Si Wuya was deep in thought and did not dare to disturb him easily, so they waited aside.

I don’t know how long I waited, but I just sat on the ground and fell asleep while I waited.

By the time Zhu Honggong opened his eyes, night had fallen.

Si Wuya finally regained his composure and said, "Eighth Junior Brother...Eighth Junior Brother?"

"Yes, yes..." Zhu Hong was excited and yawned.

"You go back and rest first. I'll give you the answer tomorrow morning."

"oh."

Zhu Hong stretched his body and walked out of the Thought Cave.

When I walked outside, I looked back and saw that Brother Seventh was out of his mind. Isn't it just a boring question? How could it be so serious?

…

Early the next morning.

Lu Zhou slowly opened his eyes.

I feel refreshed and indescribably comfortable.

It may be that the opening of the new Heavenly Book has brought about greater changes in Luzhou than before.

He looked at his white hair and saw that it had more black hair than before.

Compared with the time when we first crossed over, the changes are quite big, but compared with yesterday, the changes are not big.

[Ding, training Si Wuya has gained 200 merit points. 】

Um?

Is this okay?

Lu Zhou stood up, came to the desk, and started writing again, rustling...

After finishing writing, people called Zhu Hong over.

"Disciple pays homage to master." Zhu Honggong was very positive.

"Come in."

Zhu Hong walked into the room and saw that Master had just put down his brush. He chuckled and said: "Master, the seventh brother has not been able to solve the problem you have raised all night. He is so worried that he has dark circles under his eyes!"

Lu Zhou was slightly startled.

Judging from Ji Tiandao's memory, the development of mathematics in this world is indeed not very good, and it is impossible for people to use modern thinking to solve problems like modern people. But problems like this should not be difficult for Si Wuya.

Why can't you figure it out?

"Give him the questions on the table."

"Disciple, I obey."

"One is the answer to the previous question, and the other is the new question."

"Disciple understands."

Zhu Hong took the answers and questions together, left the East Pavilion, and came to Si Guo Cave.

As soon as he entered the Siguo Cave, he saw Si Wuya who was not in a good mental state and nodded repeatedly.

"What a wonderful question! What a wonderful question!" Si Wuya said.

"Greetings to the Seventh Senior Brother." All the Hongs bowed together.

Si Wuya turned around, grabbed Zhu Honggong, and said, "Is this really a question asked by Master?"

"Of course, I saw Master with my own eyes using his pen and ink... unless I'm blind!" Zhu Honggong said firmly.

Si Wuya was a little shocked and confused: "Master doesn't look like a smart person..."

Zhu Honggong: "Cough cough... cough cough..."

Si Wuya also realized that he had said something wrong and quickly said: "Fortunately, after a night, I solved the problem."

"Senior Brother Seven is awesome!" Zhu Hong extended his thumbs up.

"Just getting by."

In fact, Si Wuya was not very satisfied with his solution to the problem. After all, the problem seemed very simple, but it actually took him all night. The stupidest way was to go directly to the farmer's house to grab a bunch of them and put them together. He could even count them better than him.

Calculate quickly.

"Master gave this to you." Zhu Honggong handed over the rice paper.

Si Wuya was a little depressed at first, but when he saw a new topic, he immediately became energetic.

He saw the first piece of paper written: Rabbit Twelve, Pheasant Twenty-Three.

"Master also knows the answer?" Si Wuya was shocked. The answer was exactly the same as the one he had just answered. How could he not be surprised? Although the answer was found, he really couldn't be happy.

"Master asked the question, of course I know the answer." Zhu Hong agreed.

Si Wuya looked at the second piece of rice paper:

“Today there are things whose number I don’t know. When I count threes and threes, there are two left. When I count fives and fives, there are three left. When I count sevens and sevens, there are two left. What is the geometry of the thing?”

After reading this question, Si Wuya frowned.

This is a question that is not inferior to the previous question.
