Tianchi Fang.

An underground vault.

The walls of the chamber were carved with runes, giving off a faint glow......

These runes seem to contain endless wisdom and power, giving people an indescribable mysterious atmosphere.

Ding Yufeng stood in the center of the secret room, the golden aura in his hand flickering.

She raised her hand and threw it, and the eight-sided golden abacus was suspended in the air, emitting a dazzling light. Each abacus is inlaid with delicate charms......

This eight-sided abacus represents the different directions and elements of the eight trigrams, and they intersect with each other to form a complete formation. A golden light spread through the chamber......

Ding Yufeng's eyes stared at these suspended abacus, and her fingers gently swiped through the air, guiding the flow of energy between the abacus. A golden aura flickered on the abacus.

"Abacus beads, ninety-nine to one, count the beads, calculate the heavenly machine." With Ding Yufeng's loud chanting.

The air in the chamber seemed to freeze......

The golden abacus fell one by one, and a gossip pattern was formed, with the golden jade phoenix in the center, stepping on yin and yang, controlling the rhythm between heaven and earth.

Her fingers brushed the abacus, and the golden light flickered on her fingertips, as if countless stars were dancing in her hands.

The yin and yang qi in the Bagua pattern began to flow, and the yin and yang intertwined with each other, forming a delicate balance.

Ding Yufeng stepped on the lotus flower and fell outside the complex bead hub.

Looking at the bead secret room he had just cast, Ding Yufeng said with a satisfied face: "It's done." ”

"Each abacus is inlaid with nine Tianhui jade beads, which is a total of seventy-two Tianhui jade beads. At that time, the bead privy hall jointly cast by our three major families only had ninety-one Tianhui jade beads on each abacus. Ding Yufeng clapped his hands and said.

"So the computing power of the entire account room is not as good as an abacus in the Zhu Privy Palace?" Li Shuidao frowned and asked.

"Back then, our three major families spent a lot of manpower and material resources in order to cast the Bead Pivot Secret Palace, and the spirit stones used to buy the Pearl of the Sea of Clouds were not less than 300,000, although your bead pivot account room was only refined with surplus materials, but although the sparrow was small, it was complete, and the computing power was also extraordinary, but it could not handle the exploits of hundreds of thousands of people, and it was easy to deal with the debts of hundreds or even thousands of people." Ding Yufeng said confidently.

Li Shuidao looked at this large magic weapon dedicated to calculus, and asked curiously, "Can this thing calculate complex borrowing problems?" ”

Ding Yufeng replied with a smile: "The dzi abacus can be used to calculate the fate of all things in heaven and earth, and even people. ”

"How can I use it?" Facing this huge algorithm, Li Shuidao was at a loss.

"Just enter the number you want to calculate, and it will do the math for you." Ding Yufeng is very simple to say.

Li Shuidao's brows furrowed slightly, and after thinking for a while, he said, "Then I'll come up with a triangular debt problem." ”

"Say it."

"A borrows 1,000 spirit stones from B at a monthly interest rate of 10%; B borrows 2,000 spirit stones from C at a monthly interest rate of 12%; C borrows 3,000 spirit stones from A, with a monthly interest rate of 15%, and the loan term is 100 years, calculating compound interest, and how many spirit stones should each person repay to the other party after 100 years. Li Shuidao said slowly.

If this problem is calculated by manpower, it is enough for three bookkeepers to calculate for four or five days, and the bookkeepers are prone to errors.

Ding Yufeng glanced at Li Shuidao unexpectedly, she didn't expect the loan problem encountered by Tianchi Fort to be so complicated, she played a trick against the eight-sided abacus magic weapon, and recited the incantation in her mouth: "Abacus beads, ninety-nine to one, count the beads, calculate the heavenly machine." ”

With Ding Yufeng's recitation, the nine beads on the eight-sided abacus began to beat on their own, and the entire magic weapon operated. After three or four breaths, the beads stopped beating.

Ding Yufeng stared at the number projected by the magic weapon and said, "A should return the spirit stone 1048576 B, B should return the spirit stone to 2097152 C, and C should return the spirit stone 4194304 A." ”

Li Shuidao nodded with satisfaction, this calculation speed is far better than manpower.

"How does this thing deduce the heavenly machine?" Li Shuidao asked curiously.

"This algorithm can only provide computing power, and if you want to deduce the heavenly machine, you must use a special heavenly machine deduction technique." Ding Yufeng explained.

"Can the Five Poison Sects have the inheritance of deducing the Heavenly Machine?"

Ding Yufeng shook his head: "The Five Poisons Sect does not have this kind of secret technique, I heard that there is a sect in Penglaihai with a sparse inheritance, and the monks in the sect use the Nine Palace Turtle as the same staff, and they are good at deducing the technique of Heavenly Destiny, but other than that, I have never heard of this kind of inheritance." ”

"Alas......" Li Shuidao sighed when he heard this, looking quite regretful.

According to Li Shuidao's plan, after the completion of Tianchi Fang, he will pay off all domestic debts, only keep a few foreign debts, and only particularly valuable people will be eligible to enjoy the interest of Tianchi Fang, so that the amount of calculation is not large, and a few account rooms can definitely be calculated, but he still has to insist on making Zhushu account room is to obtain and have a rare algorithm.

After all, deduce the heavenly machine, the Dao method, and the life technique. It will certainly be of great help to my future practice.

It's a pity......

Without the corresponding calculus method, such a rare treasure can only be used to settle accounts.

……

Tianchi Fang

Central Plaza.

The sun shines through the blue sky and shines on the square, creating a bright scene.

The floor of the square is made up of carefully laid bluestone slabs, smooth and neat, exuding a faint fragrance.

The group came to the square......

Ding Yufeng patted the storage bag and took out a huge spirit boat. This spirit boat was like a giant ship, the hull of the ship was made of high-grade spirit wood, exuding a faint golden light. The hull is delicately carved with patterns, delicate and gorgeous, like a work of art. The cabins of the Coffin are spacious and luxurious, decorated with ornate silks and precious stones, giving it a sense of luxury.

"Five fellow Daoists, you've worked hard these days, be careful, don't pay respect." Li Shuidao took out the spirit stone from the storage bag and gave it to the five hook and sickle guards, each of whom had a high-quality spirit stone.

There are a total of five spirit stones, only one of which is a water-attribute spirit stone, and the rest are metallic spirit stones. These spirit stones shimmer with a mesmerizing light and exude a powerful aura.

These five "hook and sickle guards" are naturally the juniors of the Ding family, and Ding Yufeng came to Tianchi Fort to bring them, just to let them move something.

One by one, they hung up the "hook sickle" to show their identity as "hook sickle guards".

Under the operation of Lao Wang Ba, the Li family is now mining spirit stone mines in Scorpion Valley, and has excavated a large number of metallic spirit stones, and these metallic spirit stones cannot be spent directly, otherwise the Five Poison Sect must know that they have dug up the spirit stone mine, and they must be washed through the fang market, which involves a lot of calculations, and the newly refined algorithm can also play a great role.

Ding Yufeng said: "There is no banquet in the world, and Lord Li still has many important things to deal with, so there is no need to send them off. ”

Li Shuidao replied with a smile: "I asked Xia Ruoxue to escort you back, and when you arrive home safely, I will let her come back." ”

Ding Yufeng shook his head: "It doesn't have to be like this. ”

"Yes, yes." Li Shuidao looked very resolute, he gave Xia Ruoxue a look, and Xia Ruoxue immediately jumped on the spirit boat.

"This ...... The castle lord is also too polite. Ding Yufeng sighed, and could only take Xia Ruoxue to leave in the spirit boat.

Li Shuidao stood on the square, looking at the Lingzhou in the distance, his expression became extremely solemn, he patted the storage bag and took out a note, slowly unfolded it, there was Ju Mu Jinjuan's handwriting on it, and green fire suddenly appeared from his fingertips, the poisonous fire burned, and the small note instantly turned into ashes.

The giant wooden spirit boat flew high in the sky, and white clouds naturally grew under the spirit boat, holding this spirit boat and sailing quickly.

Suddenly.

Three monks riding golden eagles flew from three directions, and their speed was amazing, like three golden lightning bolts.

Xia Ruoxue shouted for the first time: "There is an enemy attack!" ”

Ding Yufeng's face was solemn, she played a trick and pressed it towards the central jade platform of the spirit boat.

There is a magic circle on the jade platform, and five medium-grade spirit stones are inlaid on the formation.

The formation suddenly shot out a huge amount of spiritual light, and the medium-grade spirit stone embedded in the groove consumed the spiritual power quickly, and the speed of the spirit boat skyrocketed, but it still couldn't get rid of the pursuit of the three-headed giant eagle.

Ding Yufeng shouted sharply: "It's the Wind Wing Giant Eagle, it's the monk of the Divine Eagle Gate!" ”

"I'm going to kill them!" Xia Ruoxue jumped out of the spirit boat.

"Quack quack...... "As the bone skeleton quacked, she had an extra bone giant knife in her hand.

Facing the oncoming wind-winged giant eagle, Xia Ruoxue threw out a plasma pill.

Bang!

With an explosion, a cloud of blood enveloped the windwing eagle in front of it.

The Windwing Giant Eagle was extremely fast, and almost instantly rushed out of the blood cloud, but the terrifying thing was that the monk on the back of the Windwing Giant Eagle had been turned into dry bones.

He had a huge penetrating wound in his chest, and not only was he slashed with a knife, but his whole body was sucked out of essence and blood.

This was the first enemy Xia Ruoxue killed.

She didn't stop, harnessing the blood cloud to pounce on the second Windwing Eagle.

The remaining two wind-winged giant eagles flew far away, not daring to engage them in the slightest.

In the giant wooden spirit boat, a flying sword flew out, and the sword surged, and with a single sword, it slashed the wind-winged giant eagle that had lost its owner, and blood splashed on the side of the ship.

A flash of light shot out, and the body of the wind-winged eagle was also photographed on the ship.

It was Ding Yufeng who made the shot, and she easily killed a wind-winged giant eagle that no one controlled.

A hooked scythe reached out and ripped a storage bag from the withered corpse of the Windwing Eagle, along with a pitch-black skull token.

When the hooked scythe saw the token, his face changed dramatically.

He raised the token with both hands and came to Ding Yufeng's life and said loudly: "Auntie, it's not good! This is the killer token, and these three people are secret door killers. ”

"What's the panic, it's just three fools who are sent to death." Ding Yufeng said lightly.
