Chapter 643 Machine

Simim Island.

On the back of the island, under the towering rock wall, the Discovery was shaking gently with the undulations of the deep sea water.

Sifa leaned against the side of the boat, enjoying the sea breeze.

It's already March, and in the past week, Xifa stayed in Bayam City, secretly inquiring about the news of the 'Dark Emperor' through various channels, but unfortunately there was no result at all.

However, through collecting from various places, the potion ingredients of the 'machine' were gathered together. Gregor was promoted to 'machine' yesterday.

that is

"Quack, make a question! Make a question! Give me a question, my calculation soul is burning."

On the shoulder, Gregor fell into an abnormal excitement. He didn't know whether it was related to the potion or the nature of the parrot. In short, after the promotion, it became very noisy.

"I know, I know."

Xifa sighed, covered his ears, and tried to recall the math problems he had learned and seen in his previous life, and then said casually: "Put a rooster and a rabbit in a cage. From the top, there are 35 heads. From the bottom, there are 35 heads. , with 94 feet."

"Tell me, how many cocks and rabbits are there?"

"Quack, it's too simple."

Gregor flapped its wings and flew to a small blackboard prepared by Sifa. The parrot picked up a piece of chalk in its beak, and made gestures on the blackboard while talking: "Suppose all the cages are regarded as roosters, then There are 35 chickens in total, and each chicken has 2 legs, so there should be 70 chickens."

"This is 24 feet less than the total number of known feet, and the reason for the reduction is that each rabbit has 2 fewer feet."

"So, look at how many 2 are missing out of the 24 feet, you can find out the number of free ones, and then find out the number of chickens."

"Therefore, the formula should be like this!"

Swipe.

Gregor quickly wrote down a series of formulas on the blackboard.

(94-2*35)/(4-2)

=(94-70)/2

=24/2

=12 (only)

"If there are 12 rabbits, there are 23 chickens!"

Gregor put down the chalk and flapped his wings: "Is that all? Can you only come up with such simple questions in your mind? Is your brain eaten by a living corpse?"

The muscles on Sifa's face twitched slightly, with the urge to strangle Gregor to death.

"I'll give you one."

Adjutant O'Neill was eager to try: "This is a difficult problem that the teacher assigned us when I was in college. It took us a long time to figure it out."

Gregor suddenly shouted excitedly: "Hurry up, hurry up, what is the problem, I want to calculate it!"

After cleaning the blackboard, O'Neill drew a nine-square grid on it, and then said: "You need to fill in the nine spaces with the nine natural numbers from 1 to 9, let the three numbers on the horizontal, vertical and diagonal lines, add It all adds up to 15."

Xifa rubbed his face, feeling like he was in math class in his previous life.

Gregor became quiet for a while, then flew to the blackboard and started talking again: "1 plus 9 equals 10, 2 plus 8 equals 10, 3 plus 7 equals 10, 4 plus 6 equals 10." If you add 5 to the sum of each logarithm, it will be equal to 15, so the center box should be filled with 5!"

O'Neill suddenly opened his mouth slightly, apparently not expecting Gregor to grasp the key to this question so quickly.

"Next, the four groups of numbers just mentioned should be filled in the horizontal, vertical and diagonal positions respectively. First fill in the four corners. If you fill in two pairs of odd numbers correctly, then it is possible to get an odd number because of the sum of three odd numbers. , the cells on the four sides can no longer be filled with odd numbers, so this method will not work.”

Gregor croaked again and again: "If the four corners are filled with a pair of even numbers and a pair of odd numbers, well, it won't work either."

"In this way, it is obvious that two pairs of even numbers must be filled in the four corners. After the numbers on the diagonal are filled in, it will be easy to fill in the odd numbers in the remaining grids, so... the answer should be like this!"

4 9 2

3 5 7

8 1 6

"too easy!"

"too easy!"

"Are you all curly-haired baboons? Doesn't anyone give me more difficult questions!"

Gregor flapped his wings and croaked loudly, with an aura comparable to that of a high-sequence powerhouse.

Sifa looked around, looking for a stick to stun the noisy parrot, when suddenly Gregor stopped, and then it flapped its wings and flew into the captain's cabin.

"I'm sleepy, I'm going to sleep, don't wake me up until you think of something more interesting."

After the parrot flew into the captain's cabin, Xifa's inspiration was suddenly touched, and he subconsciously turned his head to the other side of the sea.

On the undulating deep blue water, below the white clouds drifting leisurely, a blazing fire suddenly appeared.

The flames grew rapidly, flying from far to near at high speed.

Soon Xifa saw that it was not a flame, but a huge flaming spear!

He immediately subconsciously clenched the 'mutilated natural disaster spear', and the crew on board the Discovery immediately entered a battle state. But the flaming spear came too fast, and before they were ready, the flaming spear had already landed on the front of the deck.

However, the long spear seemed to be harmless, so it didn't ignite anything, and it didn't pierce through the wood. It first scattered and quickly re-formed into a figure.

He is tall and thin, wearing glasses, with jet-black hair, a high nose and blue eyes, and a well-groomed beard.

Wearing a red double-breasted long coat, there is a badge on the chest, which is the pattern of a blood-stained crown and a cross.

The other party pressed the red top hat on his head, smiled, and said to Xifa: "Good morning, Captain Rayleigh."

Xifa made a gesture to temporarily disarm the crew on board, and responded with a smile: "Good morning, Your Excellency Dean."

This is Dean Wengeris from the Jagged Cross, who I met last time near Sonia Island, an 'Iron Knight'!

After a long absence, he finally reappeared.

Xifa invited him into the captain's cabin, had someone bring black tea, and said, "Your Excellency Dean seems to be in a good mood, it seems that I will hear good news."

"It is indeed good news."

The demigod took off his hat, stood by the window, looked at the deck outside and said with a smile: "We have confirmed that Mr. Raleigh is a person worth investing in. We are willing to provide you with the potion through cooperation."

"If I guessed correctly, you should already be Sequence 5, the 'Reaper'."

"Otherwise, it's impossible for you to repel Admiral Hell and capture the pirates on the 'Deep Sea'."

Xifa was not at all surprised by the demigod's guess, he generously admitted: "Yes, I am already a 'Reaper'."

"Then, what you want to seek is the potion of Sequence 4."

Dean Wingeris turned around and said calmly, "I think you should understand that potions for demigods are not so easy to obtain. I hope you are mentally prepared."
