Chapter 23 Primary school math application questions!

60 seconds passed in a flash.

The orange's tail muscles gradually became sore and weak, and it was unable to continue to move at high speed, and the ship's speed dropped significantly.

The distance between the female ghost in embroidered shoes and Chen Changan gradually shortened.

"Damn it, I have to buy some time!"

Chen Changan recalled his experience just now. When he screamed, the girl with embroidered shoes showed a sense of happiness that could not be blocked by the dead face.

There is a saying that the female ghost in the embroidered shoes did not lie, she was indeed obsessed with the screams of humanity.

Chen Changan took out a yellow toy from the trading market and pressed it hard. The yellow toy made a strange scream. The female ghost in the embroidered shoes was slowing down by half a beat and laughed:

"Ghost thing, you like to scream, right? I'll give it to you!"

Chen Changan pressed hard, then threw it in the other direction in the air, and a strong scream came from the yellow toy.

"Ahhhhhhh~"

The female ghost in embroidered shoes instinctively rushed towards the direction where the yellow toy fell. The ghost hand suddenly stretched several meters, grabbed the source of screaming, but could not touch any signs of flesh and blood.

Taking advantage of the moment when the female ghost embroidered shoes was stunned, the flying Henan people rushed out hundreds of meters in one breath.

"What's this?"

The female ghost in the embroidered shoes looked blankly at the yellow toy in her hand.

Screaming chicken.

She pinched it.

"Ahhhhhhh~"

She relaxed.

"Ahhhhhhh~"

She was immersed in the cycle of screams, pinching, letting go, pinching, letting go again...

"Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

The embroidered shoes and the female ghost claws were too sharp. She accidentally poked a hole in the screaming chicken. No matter how she pinched it, the weak screaming chicken could no longer satisfy her XP.

She turned her head 360 degrees, leaned her head against her back, stared at Chen Changan who had escaped thousands of meters away, and said angrily:

"die!!!"

The female ghost's body, which was as light as if nothing had happened, rushed towards the flying Henan people at a faster speed.

【Elementary School Mathematics Application Questions-Chasing Questions】

It is known that Xiao Chen escapes by boat, and the speed of the boat is 15km/h per hour, and the speed will double every four minutes. The female ghost Xiaohong chases after six minutes, and moves at a speed of 30km/h. How many minutes does the female ghost have to surpass Xiao Chen? (12 minutes)

untie:

Xiao Chen’s real movement speed = 4/5*15km/h+1/5*30km/h=18km/h

During this period, Xiao Chen's escape route = 0.1h*18km/h=1.8km

Therefore, the female ghost Xiaohong and Xiao Chen are 1.8km apart.

From this we infer that

Chase time = 1.8÷(30-18) = 1.8÷12 = 0.15 (hours)

That is, the female ghost Xiaohong surpassed Xiao Chen in 9 minutes.

The teacher’s note: The process is correct, the result is wrong, and three points will be deducted.

Answer analysis: Since Xiao Chen can double the speed in the 9th minute, the female ghost Xiaohong must wait until one minute to truly surpass Xiao Chen.

Chen Changan knew very well that screaming chickens could delay for a while at most, and the best strategy was to kill the female ghost in the embroidered shoes.

If someone offends me, he will kill the roots!

Besides, she is just a female ghost.

Chen Changan did not have the feelings of a scholar from a Chinese school student, he just wanted to invite the female ghost to die.

Whether it is the treatment between him and the female ghost with embroidered shoes, or the summoning orange to run away, it is not Chen Changan's real plan.

Trading market!

As early as the moment Chen Changan woke up, he put the remaining 18 liters of drinking water in his hand in one breath.

The purchase conditions are only the same.

Special items that can kill ghosts.

After waiting for ten minutes, I finally waited for someone to place an order, and the transaction was hesitant.

【Blood of the Exorcist】

Quality: White

Introduction: After applying the degener's blood to the weapon, the weapon will have the ability to damage the weak ghosts for three minutes.

Evaluation: At least stronger than bare hands.

Chen Changan was a little worried. After applying this blood to the axe, could it cause harm to the female ghost in embroidered shoes?

First, the description of the devourer's blood does not indicate that he can directly kill the ghost. Although the seller swears that he used this blood to kill a ghost, Chen Changan just wanted to say:

"Really? I don't believe it."

Second, is the female ghost with embroidered shoes really a weak ghost?

Chen Changan felt that as a high-value white prop, the statue of Mazu can only force the female ghost to retreat several meters with a little divine power in one minute.

Can props of the same white quality really deal with ghosts?

Unfortunately, time is limited, Chen Changan did not find the second item that could harm ghosts.

After several bargaining with the trader, Chen Changan could only exchange the blood of the extermination from the opponent for a high price of 18 liters of water and 20 kilograms of fish.

"The geese are beaten all day long, but today they are pecked at the eyes."

Chen Changan monopolized drinking water for several days and finally tasted the taste of being monopolized and exploited by himself.

Fortunately, the trader seemed to have insufficient experience, and Chen Changan relied on soft and hard work to get another drop of the spirit-extinguisher's tears.

“Agree to the deal!”

"Congratulations, you have obtained the blood of the Exorcist (vial)"

"Congratulations, you have received the tears of the Exorcist"

A small mineral water bottle containing 200 ml of blood fell into Chen Chang'an's palm.

“It’s still hot.”

Chen Changan twitched his lips, and he was very suspicious that the trader on the other side might be the extermination person himself, and that the blood was released by him.

Not reliable ~

Chen Changan held the mineral blood bottle with his right hand and said with hope:

"I wonder if this blood can be upgraded by the survival point?"

…………

Time came to the "ninth minute" between Xiao Chen and the female ghost Xiao Hong. The embroidered shoes streaked across the deep sea, only twenty or thirty meters away from Chen Chang'an.

Orange followed Chen Changan's advice and gave up the ability to start a rapid diving.

In Chen Changan's opinion, there is no difference between one minute or one minute or less.

He fought with the female ghost in this battle.

There is no escape!

There is no way to avoid it!

"The teacher often teaches us not to cheat!"

"Actually, it's a hint that we must not sit still and wait for death!"

"Ghost thing, I've prepared a good job and I will definitely kill you with an axe!"

Chen Changan held the mountain cutting axe and sneered and twisted the teacher's teachings. He regarded the battle with the owner of the embroidered shoes as an important exam, and said sternly:

"Either you die or you die, there will be no second possibility."

The female ghost in the embroidered shoes glanced at the mountain-cut axe in his hand and sneered:

"That's it?"

"The blood of a mere minor extermination?"

Chen Changan looked panicked, and his trump card was seen through and he said in a panic:

"How did you know?"

The female ghost of embroidered shoes floated up, and a pair of ghost hands bullied her, almost shaking Chen Changan's throat again.

Chen Changan felt angry and shouted coldly:

"Sharp Technique! Start!"

The axe was chopped out!

Slashed straight on the shoulders and neck of the female ghost in embroidered shoes!

The moment the axe touched the female ghost's body of the embroidered shoes, the axe tip suddenly burned, making her pale skin charred in a blink of an eye.

"Well~"

The female ghost of embroidered shoes screamed in pain, but did not force it back like a god's image, but instead aroused the ferociousness of the female ghost of embroidered shoes.

A pair of ghost claws suddenly turned into scarlet color, and their fierce power was even more powerful than the past. In the blink of an eye, they pinched Chen Changan's neck.

"Orange...gulugulu~"
