[The second update today, please subscribe, monthly pass, recommended ticket, reward]

The Hakka family is a notorious family of killers. It is said that the great-grandfather, grandparents, parents and children of this family live on the dead volcano Kukulu Mountain at an altitude of 3722 meters in the Republic of Batocchia. come out safe...

In short, a family that dares to put a price tag on all life in the world is to beat the enemy family, and if you have money, you can ask them to do anything!

"..."

Hearing a lot of introductions about beating the enemy Hakka family, Feng Yuchen feels really interesting, doesn't it?

In the hunter's world, apart from the hunter's certificate, probably only the Hakka family that beat the enemy is more attractive.

Hunter IDs are attractive because

Strict examinations are held by the Hunter Association every year. Qualified people will get a hunter license, and then they can use the license according to their own wishes. They have various rights (such as free use of 95℅ public facilities in various countries), but they must also choose to do what they want. Hunters of all kinds, do their duty, such as: gourmet hunters who travel around the world in search of delicious ingredients, private hunters hired by people, treasure hunters who have undergone rigorous testing in pursuit of gold and silver treasures, search and discover many Eudemons hunters who know Eudemons, bonus hunters who hunt down criminals or illegal hunters, etc.

It can be said that with the identity of this hunter, it is equivalent to having no worries for a lifetime.

▼, w≥ww. The purpose of beating the enemy is the huge bounty. It is rumored that as long as you get the portrait below, you can get a bounty of 100 million. This is a huge sum of money. Money can do a lot of things, right?

And Feng Yuchen's purpose here today is neither the pursuit of fame nor the pursuit of money. But the pursuit of the killer's skills.

Since it is a murder family. Then there must be a lot of killing technology.

After coming to the door. Feng Yuchen saw a thick and huge door laying in front of him. There were seven groups of doors from bottom to top.

"Little guy, hurry up and get out of here, this is not a place for you to play..."

A bald old man walked out of the guard room next to him and waved to Feng Yuchen and Lilith.

"Old man, is this the Hakka family that beats the enemy, the killer organization with the most powerful killing techniques in the world?" Feng Yuchen asked.

"So what? Well,

To visit tour and words. That's it, let's go quickly..." The old man said impatiently, squinting and yawning.

"Then that's right. I want to learn from a teacher. This is the door of the test, right?"

Feng Yuchen pointed at the heavy iron gate in front of him and said.

"Apprenticeship to learn art? Ha? Don't be a player. I've lost so much here. I haven't heard of the saying that a teacher beats an enemy guest. They are a family of killers that are passed down from the inside but not the outside world, and they won't teach you to kill. Skilled, let's go..."

The old man opened his eyes in surprise, these two little guys actually wanted to learn from a teacher. Are you delusional?

Are you fed up?

Who is not good to be a teacher, to be a teacher and beat the enemy. It's so delusional.

"Nini, don't talk nonsense with him, let's go in directly from there..."

Lilith stretched out her white fingers and pointed to the side door.

"No, since it exists, there is a reason for it. We don't need to enter that door. Let's go in from the front..."

Feng Yuchen stretched out his arms and looked at the heavy iron door in front of him. It is estimated that this is the door of the test. If you want to enter it, you must enter from here.

"Wait... Hey, don't think about it, you can't open this door. The main door of the enemy Hakka does not need a key. It is called the door of trial, and it is also called the door of Huangquan. There are a total of 7 doors, one Each door is two tons on the left and right, and each additional door doubles the weight. The greater the force, the larger the door can be opened...

The bottom one alone would weigh 4 tons to open..."

The old man sighed and said that apart from beating up the children in the enemy's house, he didn't believe that anyone would be able to open this door.

"Four tons? It seems to be a bit of a test, but it doesn't matter, it's okay to push it away..."

Feng Yuchen's current strength is that the strength of 1200 kilograms in both hands is still a long way from 4000 kilograms, but the thrust of 1200 kilograms is not only able to push 1200 kilograms of heavy objects.

Pushing the door requires thrust, not a force of 4t (tons) to be able to push. In physics, if the orbit is horizontal and there is only one object, to calculate the thrust, apply the sliding friction formula, f =μn, f is the friction force, n is the pressure, and μ is the friction coefficient. Under normal circumstances, the static friction coefficient of steel is 0.15. This is in the case of no lubrication, that is, a thrust of 600 kg is required.

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

Even if other various coefficients are added, it will not exceed 1000 kg of thrust.

So it's easy to push the first door open.

Moreover, Feng Yuchen felt that the two doors should not reach the friction coefficient of 0.2.

So Feng Yuchen estimates that if he exerts his full strength, he should be able to open the second door, right?

Or if you cultivate more powerfully, you can push them all away.

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

For example, some rumors that the old lady lifted the car to save the little grandson, although it is a bit exaggerated, but it is groundless and must have its true existence.

Just like the four or two in Tai Chi, the existence of Nuo Da is only a matter of time as long as you master the tricks and push it away.

Feng Yuchen thought about going forward, pressed all the gravity on his legs, and then put his hands on the door.

rise! !

Feng Yuchen's eyes turned into a pair of yin and yang pupils at this moment, the heaven and the earth seemed to disappear, his feet stepped on the yin and yang, immersing the four meridians, and through the transmission of the earth, a force was also conveyed from the ground to the wind and rain. In Chen's body, at the same time, it merged with his original strength and gathered on his hands.

"Om...kachacha..."

For a time, the third door was slowly opening...

"open!"

Feng Yuchen's body seemed to be swept away by an inexplicable breath, his long black hair fluttered, and the two doors in front of him were instantly opened!

After calming down, Feng Yuchen entered the door, 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, just open the second door, the first one. If you don't want to come in, you can only move forward if you are strong..."

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

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