[today's second more, for subscription, monthly ticket, recommended ticket and reward]

beat the enemy family, a notorious killer family. It's said that the family's great grandfather, grandparents, parents and children live on the withered killing mountain of the dead volcano 3722 meters above sea level in the Republic of batochia, and they want to kill people every day, but the last one doesn't come out safely

In a word, a family that dares to price all the lives in the world is a family that beats enemies. If they have money, they can do anything!

“……”

I've heard a lot of introductions about beating enemy families. It's really interesting, isn't it?

In the hunter's world, in addition to the hunter's ID card, probably only this beating enemy family is more attractive.

The reason why the hunter's certificate is attractive is that the hunter's association holds a strict examination every year, and the qualified people will get the hunter's license, and then they can use the license according to their own will. They have all kinds of rights (such as free use of 95% of public facilities in various countries), but they must also choose to be the kind of Hunter they want and do their duty, such as traveling They are food hunters seeking delicious food, private hunters employed by people, treasure hunters pursuing gold and silver after strict tests, magic hunters who find many unknown magic beasts, bonus hunters who hunt down Tongyi criminals or illegal hunters, etc.

It can be said that with this hunter's identity, it is equivalent to a lifetime of Huzhu not worry.

The attractive purpose of beating enemies is their huge reward. It is said that as long as you get the picture below, you can get a reward of 100 million. This is a huge sum of money. You can do a lot of things with money, can't you?

The purpose of fengfengchen's coming here today is not to pursue fame or money, but to pursue the skills of killers.

Since it's a homicide family, it must have a lot of killing skills.

After arriving in front of the door, fengfengchen saw a heavy and huge door across in front of him. There were seven groups of doors from bottom to top.

"Little guy, get out of here. This is not your place to play..."

A bald old man came out of the guard room and waved to the rain and Lilith.

"Uncle, is this the family of beating enemies, the killer organization with the most powerful killing technology in the world?" Asked the storm.

"So what? Well, to visit the tour and talk, so far, let's go quickly... " The old man squinted and yawned impatiently.

"That's right. I want to learn from my teacher. Is that the door to the test?"

The wind and rain Chen points to the front heavy iron gate to say.

"Learning from teachers? Huh? Don't drive players. I've lost so much here. I haven't heard of the saying that there is a master to beat the enemy. They are a family of killers. They don't teach you how to kill. Let's go... "

The old man was surprised to open his eyes, these two little guys actually want to learn art, some delusion?

Are you full?

Who is not good to be a teacher? It's really paranoid to be a teacher and beat the enemy.

"Nini, don't talk to him anymore. Let's just go in there..."

Lilith pointed her white finger to the side door.

"No, since it exists, it has its reason. We don't need to enter that door, just go in from the front..."

The wind and rain Chen stretched his arms and looked at the heavy iron door in front of him. It was estimated that this was the test door. If you want to enter it, you must enter from here.

"Wait Hey, don't be paranoid. You can't open this door. You don't need a key to beat the main door of the enemy Hakka. It's called the gate of trial training, also known as the gate of the yellow spring. There are seven doors in total. One door is about two tons each. Each more door weighs twice as much as the other. The greater the strength, the bigger the door can be opened

The bottom one alone weighs 4 tons to open... "

The old man sighed and said that he didn't believe anyone could open the door except for beating the Hakka children.

"Four tons? There seems to be some tests, but it doesn't matter. It's OK to push it away... "

The current strength of wind and rain is 1200 kg in both hands, which is a long distance away from 4000 kg, but the thrust of 1200 kg is not only able to push 1200 kg of heavy objects.

To push the door, it needs thrust, not 4T (tons) force. In physics, if the orbit is horizontal and there is only one object, the formula of sliding friction can be used to calculate the thrust. F = μ n, f is friction, N is the pressure, μ is the friction coefficient. Under normal conditions, the static friction coefficient of steel is 0.15, which is in the case of no lubrication, that is, 600 kg of thrust is required.

The door in front of us is probably cast iron. If it is cast iron, the dynamic friction coefficient without lubrication is about 0.2, which is 800 kg.

Even with other coefficients, the thrust is less than 1000 kg.

So it's easy to push the first door open.What's more, I feel that these two doors should not reach the friction coefficient of 0.2.

So if you try your best to exert your strength, you should be able to open the second door, right?

Or if the cultivation is more powerful, it's OK to push it all away.

After all, the use of power is very strange. Isn't there a term called potential?

For example, some rumors about the old lady lifting up a car to save her little grandson are exaggerated, but they are true.

It's just a matter of time before nuota can exist, just like the four or two thousand catties in Taiji.

Fengfengchen wants to step forward, press the gravity on his legs, and then stick his hands on the door -

up!!

At the moment, fengfengchen's eyes turned into two pupils of yin and Yang like Yin and Yang, and heaven and earth seemed to disappear. With the transmission of the earth, a force from the ground was also conveyed to fengfengchen's body, and at the same time, it combined with his original strength and gathered on his hands -

"hum Click... "

For a moment, the third door slowly opened

"Go

The body of the wind and rain seems to wash out the inexplicable breath, the long black hair is flying up, and the two doors in front of us are unfolded instantly!

After calming down, fengfengchen entered the door, and then turned to Lilith and said, "if you want to follow me, just open the door like me. If you can't open the third door, open the second one. If you want the first one, don't come in. Only Qiangda can move forward..."

"Oh! ~Nini, Lilith will work hard... "

Lilith made an expression that I could, waiting for the door to close, and then stood in front of the door to open it.
