Ten minutes later, Liu Xinmei showed a hint of emotion on her face and left Ye Feng's room.

Ye Feng is not a saint, he naturally has seven emotions and six desires, and he cannot reach the realm of preserving heavenly principles and destroying human desires, but Ye Feng has his way of doing things, and in his heart, there is a scale to measure all things in the world.

In fact, when Ye Feng chose for Chen Yalu and other nine women, when Liu Xinmei chose to stay, she was already destined to have an evolution liquid, but in order to better train them, Ye Feng did not directly give them the evolution liquid, but let them obtain the evolution liquid by hunting zombies, which was to let them understand that there was no unearned gain.

The experience of twenty years in the last days made Ye Feng abandon a lot of things, and he also liked to use numerical values to measure the vast majority of people around him, that is, the so-called "stock theory" of some celebrities before the disaster.

The so-called stock theory is that everyone has a price in Ye Feng's heart, for example, if you don't know someone, the price is naturally zero, and when Chen Yalu's three daughters choose to stay, their price is one hundred.

The price of one hundred, with their performance, has risen and fallen, for example, Chen Yalu has performed well, and it has a great effect on Ye Feng, the price has risen from one hundred to five hundred, otherwise, this price will fall.

Once it falls to zero, Ye Feng will give up, if he does something that damages Ye Feng too much, such as betrayal, then it will not only fall to zero, but directly become negative.

Becoming a negative number is equivalent to an enemy, and at the right opportunity, Ye Feng will kill him.

A positive number is a friend, a zero is an inconsequential stranger, and a negative number is an enemy.

The greater the positive number, the more important the person's position in the heart, and the greater the negative number, the more determined the other person needs to kill.

For example, a person with a negative number of 50, if he falls into a group of zombies, Ye Feng doesn't mind giving him a shot, if this shot will bring trouble to himself, Ye Feng will endure it, after all, a negative number of 50 is just a little murderous, and he can't take risks.

If it is a person with a negative number of 500, then even if he takes a little risk, Ye Feng will kill him, this negative number is even greater, so big that even if Ye Feng does not want to die, he will die with him.

In the same way, the positive number is the same, the positive number of 50 people fall into the corpse group, Ye Feng's rescue may be dangerous, he will give up, if it is a positive number of 500 people, take the risk to rescue, if the positive number reaches a certain number, even if he dies, he must be saved.

Anything in the world, in Ye Feng's eyes, has its position.

Liu Xinmei chose to stay, got a positive number of 100, the first time she went to kill zombies, in the fund-raising housing community, Liu Xinmei saw dozens of zombies rushing out of the unit building, gave up her teammates, turned around and ran, deducted 50, and it was still positive 50.

But if Liu Xinmei makes such a mistake once, and another deduction of 50 is equal to zero, Ye Feng will choose to give up on her and leave her to fend for herself.

However, Liu Xinmei did not make a mistake, she honestly killed zombies, although she was a little suspicious of soy sauce, but at least she was abiding by Ye Feng's regulations, and it rose by 50 again, reaching a positive number of 100.

The first-level evolution liquid, in Ye Feng's eyes, the value of positioning is 100, so even if Liu Xinmei had already obtained an evolution liquid when she chose to stay, but in order to better train her and let her understand the truth of giving and reaping, she has not been given to her.

This is also why Ye Feng said some seemingly incomprehensible words to her tonight, because anyone with a positive number of more than 100 is already the standard of a friend in Ye Feng's eyes.

Ye Feng's numerical theory, in fact, before the disaster, many people were using it imperceptibly, but they didn't know it.

For example, if a friend with an average relationship borrows money from you, you may only borrow 200, and a brother who has played from childhood to adulthood lends you money, and you will borrow 5,000 money.

And a stranger suddenly borrows money from you, and you naturally won't borrow it.

In the same way, the person who can lend 200 from you, in your heart, is the value of 200, and 5000 is the value of 5000.

Some people who value feelings will naturally position their feelings very high, and some people who pursue profits will position their interests very high.

In their eyes, parents, wives and children are the sky, the earth, and everything in life, and naturally their parents, wives and children are priceless in their eyes.

On the contrary, those who are heavy on profits will also take their wives as young ladies, sit outside to collect money, and when the guests leave, they will also ask the guests, how is the service? Not satisfied?

In fact, these two kinds of people are using numerical theories, people who value feelings, parents, wives and children are priceless, but they don't know that pricelessness is also a price, but this price is infinite.

This set of numerical theories, in fact, is used by everyone, but Ye Feng has made him more concrete, more systematic, and more standardized, forming his own set of principles for doing things, that is, his "Dao".

Just like many craftsmen use trigonometric functions when they are working, but they don't know it, mathematicians have systematized trigonometric functions into a very complete set of mathematical textbooks.

This is why some people say that everything in this world has a price, while some people oppose it and think that some things are priceless.

The reason for such a difference is only because the angle of the station is different, the positioning is different, and the natural seeing is different, this is everyone's "way", different paths to the same end, in fact, their own positioning is different.

This is also the old saying, the Tao is different, not allied, the gentleman is not the party, and the villain is not the party.

Although Liu Xinmei is timid, she is not stupid, when she heard some of Ye Feng's words, she knew in her heart, and she also felt that Ye Feng was right, and she was the most reliable person in the world.

Lean against the mountain, and the mountain will fall. Rely on people, people will run. Only on your own is the most stable, because you can't run away.

It's like thinking about how to please others with your body, but it's better to think more about how to become stronger.

Because Ye Feng has a rod and scale in his heart, he will look at things from an objective and rational point of view, and he can go straight to the essence through phenomena.

After Liu Xinmei left Ye Feng's room, she came to the bathroom, took off her hot flight attendant uniform, stripped naked, stood under the shower, let the cold water sprinkle on her face, and then flowed from her face.

Stimulated by the cold water, Liu Xinmei shivered, but she still held back, and after a few minutes of cold water, her body quickly adapted to the cold water at low temperatures, and she didn't feel the biting coldness.

At this moment, Liu Xinmei herself is slowly transforming, and at this moment, she found that she actually had some feelings for Ye Feng, and this feeling had nothing to do with her status and status, but just a simple good feeling.

Thinking back to everything Ye Feng did during this time, although it seemed to be very strict with her, it was not training them.

Ye Feng is like a whetstone, grinding away their arrogance and luck, so that they can clearly understand what kind of era it is now.
