It took more than half an hour to return to the ground.

Zhang Ping had a feeling that it was not the same way to return.

Unfortunately, I couldn't see anything with my head hood. I opened it and found that it was already late at night.

The big bell in the yard happened to ring: it was exactly two o'clock in the morning.

Weary swept over.

Zhang Ping and the other six who had just completed their transfer could not help but yawn, one after another.

This day passed, I was worried.

Chen Ying's cold voice came: "Let's go first, you can go home and have a day off after dawn. We will gather for training the morning after tomorrow.

By the way, remember to write down your job transfer process after you get home, the more detailed the better.

If you write well, you will be rewarded. Last time someone’s job transfer process report was reported, Master Huang rewarded 5,000 yuan.”

"Wow……"

Zhang Ping couldn't help but exclaim. It was only 5,000 yuan for him to sell himself for only 30,000 yuan.

After the six people exclaimed, they gradually became active and began to exchange names with each other:

The most active ones are Zhang Ping, Huang Lijun, the 'polite' Zhao Bin, and finally the relatively silent boy, Zhou Hao.

Two girls, Wu Qianqian and Feng Xue.

Both of them are very thin, and they are only exposed to their sharp corners when they are seventeen or eighteen years old; Feng Xue is a little darker and stronger.

Entering the arranged temporary rest point, the six people fell asleep.

There are six camp beds in a row, not very clean.

Everyone was tired and scared.

There were 36 people, 30 died, and Master Huang actually said "yes" with joy.

However, some people are so excited that they can't sleep. For example, Zhang Ping.

My eyes closed, but I was actually looking at the system, checking the manual, and thinking about the problem of the technology tree:

Although the job transfer is successful and the strength can reach 1 ton, it does not mean that you can perform perfectly.

In theory, ordinary adults can lift 200 to 300 kilograms, but how many can they really do it.

Not to mention, the system also warned: it is not perfect yet.

Zhang Ping thought about the contents of the 'instructions':

To be "perfect", we also need a mechanism for transmitting power, that is, various mechanical structures are needed.

These structures can be selected from the system or designed by yourself; some things can be input from the outside world, such as alchemy products.

But Zhang Ping doesn’t have many choices.

It takes money to buy outsiders, and a lot of big money is enough.

Design your own...design a hammer.

Therefore, you can only choose from the system for the time being.

The first-level technology tree can be selected: connecting rod system, windmill system, waterwheel system, torsion spring system, pulley system, winch system, etc.

In addition, there are basic items, such as iron chains, cold weapons, etc.

They are all simple and basic things.

"Windmill system, waterwheel system, pulley system...it looks like it, the connecting rod system is simple and efficient."

After thinking for a long time, Zhang Ping made a decision:

Choose the linkage system and design part of it yourself; buy some design data directly from the system.

“Light up the connecting rod system!”

[Dingdong, please choose the host.

1. Full connecting rod system, which can be used directly: valued at 6000 source power + 100 contribution;

2. The blueprint of the full connecting rod system, with a value of 60 sources + 1 contribution;

3. Design or part of the design blueprint yourself, or customize the blueprint, you can provide scientific theories, design data, etc., and the specific value can be calculated separately.]

"Sure enough, it's not cost-effective to buy physical items directly, so it's better to design it yourself. It's not too late to buy the blueprint if you don't have the design success."

Zhang Ping clicked on the third option, and the first thing he showed was the fill-in-the-blank question - scientific theory or definition.

Ordinary connecting rods are the simplest and most basic machinery, and are the force transmission structure. Generally, the connecting rod itself is required, and more than two link points are usually drilled.

The core of the connecting rod system is actually a series of levers.

The theory of leverage is simple:

Composition: fulcrum, power and power arm, resistance and resistance arm.

Theory: The product of the power and the power arm is equal to the product of the resistance and the resistance arm, plus the resistance at the fulcrum.

Ideal: Give me a fulcrum and a golden cudgel, and I can lift the Lingxiao Palace.

The theory is filled in, and then the design of the fulcrum and connecting rod.

The connecting rod itself uses I-shaped steel structure to ensure hardness and reduce weight;

The connecting rod drilling position is used to make reinforcement reinforcement;

Try to be thicker in the fulcrum, and add a sleeve between the fulcrum and the connecting rod;

It’s not that I don’t want bearings, but that “bearing”, a simple thing, is not something of a first-class technology tree.

After the setting was over, Zhang Ping purchased data from the system.

[Data: 20 source power + 1 contribution]

"Sure enough, this design is more cost-effective. But contribution... tsk, this thing is not easy to work with."

[Dingdong: The host's description of the connecting rod system, etc., has reference value and can be sold to the system, with value: 10 contributions.

whether】

How could this be done? Of course...no!

Zhang Ping replied in his heart: "The system, the study of connecting rods and leverage, has laid the foundation for the classic physical building of the entire earth science. 10 contributions are not enough.

At least...

12 contributions!”

[In the inspection...Agree, 12 contributions. Whether it is for sale. Yes/No]

The transaction was successful. Zhang Ping received 12 contributions and used 1 contribution to purchase information.

【Zhang Ping can evolve/20 minutes)

Contributions: 11

Source: 6764

Physical constitution: soft iron/hardness 1 (100% completeness)

Strength: 1 ton

A copy of the system instruction manual

Level 1 technology tree is opened: 1 blueprint for connecting rod system]

Looking at the blueprint of the connecting rod system, Zhang Ping smiled on his face.

This connecting rod system connects the whole body through a series of connecting rod structures.

There is an eccentric chakra at the chest, and the source force is used as the driving force. Through the rotation of the eccentric chakra, the force is transmitted to the limbs, neck, toes, and fingers.

Click on the blueprint introduction:

【Basic connecting rod system (blueprint);

Power magnification: 3

Transmission efficiency per level: 90%]

"Enhance the power three times!" Zhang Ping's teeth were exposed with laughter.

After transformation, from the eccentric chakra at the chest to the fingers and toes, you need to go through the "shoulder → elbow → wrist → three knuckles", a total of 6 levels.

But it only takes three levels to pass to the wrist, palm, fist, and soles, and the efficiency can reach (90%) 3, which is about 73%.

If 1 ton of power is three times larger, including 73% efficiency, the explosive power of the wrist is about 2.2 tons!

I can hit 2.2 tons with one punch, and I will ask if you are afraid.

In the night, Zhang Ping laughed silently, his little tongue trembling.

Thanks to my friends who have already fallen asleep, otherwise they would be scared and trembling by Zhang Ping.
