Earth, Gaochao Village.

Mo Mo came back from another world and went back to bed to take a break.

When I woke up in the morning, Mo Mo asked his cousin to drive him to the town to purchase things.

In hardware stores, there are all tools, measuring tools, drill tools, rivets, and steel screws for woodworking. Mo Mo bought three sets of tools that were involved in making composite bows.

I couldn't understand my cousin's way, thinking that he was going to repair what toys he was going to repair. Sometimes I felt that he was so strange and had become accustomed to it.

When Mo Mo purchased tools, he returned home and went from a military composite bow online store to tell the online store the specific requirements for composite bow components. He customized hundreds of sets of eccentric wheels, axle sets, spreaders and bow shock absorbers at high prices, requiring all the materials to be made of high-strength steel.

The online store owner also said that the pound count is too large, so there is no need to kill an elephant with such a large pound count, and no one can pull it. Mo Mo explained that the composite bow is used for mechanical tension tests, but there is no explanation for it else.

When the online store owner meets a rich player, he can only customize it according to Mo Mo's request. He is afraid that he will ask too much, and the rich man will cancel the order if he is unhappy.

It was evening again, and Mo Mo moved the tools he bought this morning to another world and taught the carpenter how to use the newly purchased tools.

Compound bows are not something that quickly can be made.

During the day, Mo Mo practices piano and martial arts;

In the evening, he practiced pulleys;

At night, he practices dancing;

In the early morning, if he has time, he will go to another world.

During this period, Teacher Lu, who taught piano, also visited Mo Mo's house several times. Seeing that Mo Mo's piano level improved rapidly, he planned to let him participate in the competition.

Mo Mo rejected Lu Lei's proposal on the grounds that he had no time.

...

A few more days later.

Tianling Continent.

The carpenters have made several sets of models. Although there are measuring tools, the models made by the carpenters for the first time still have many unsatisfactory aspects.

Mo Mo asked the woodworker to modify and modify it, grind and rub it, and finally made parts that meet the model standards.

Seeing the carpenter retesting the data, he was a little confused, and Mo Mo finally figured out the reason.

He did not give the allowed dimensional error (size allowable range). Some components are made too precise and are really unnecessary, and are wasted time, which makes them inefficient;

The accuracy of some components does not meet the requirements, such as the production error between the upper and lower bows is too large, so when drawing the bow, the force under the bow body will be uneven, and the shooting accuracy will of course be poor.

After Mo Mo saw that the workers were basically familiar with the use of tools and the structure of the composite bow, he ordered them to start making parts of the composite bow.

A few days later, Mo Mo received a set of customized composite bow trial parts customized from the Internet. After being satisfied with the trial production, Mo Mo asked the online store owner to instruct the processing factory to mass production.

Mo Mo transported the goods to another world and asked the carpenters to assemble them. Soon they assembled a composite bow.

Although the compound bow is not satisfactory and much worse than the drawing requirements, it can still be used to test the arrow.

Everyone came outside the workshop to watch Shi Wu test arrows.

Shi Wu didn't dare to pull the bow all over, he was really afraid of explosions of arrows.

Hold the bow in your left hand and the arrow in your right hand. Gently pull the tool and half full of the bow, aim and release it.

Whoosh...puff!

The arrow was like light, penetrated directly into the tree trunk fifty meters away, and the arrow shaft was directly broken with a "clang" sound.

"The initial speed is 51 meters per second, the weight of the arrow feather is 120 grams, the kinetic energy E = 1/2mv2 = 156 joules, the energy from 50 meters is weak,..." The system quickly measured the shooting data.

Mo Mo got this data, as expected.

The energy required to ejaculate an adult male's chest is about 74 joules, and there is no problem with the new composite bow to ejaculate.

Like the top composite bow of the earth, the arrows shot can have 160 joules of kinetic energy, which can easily kill elephants.

A few people looked closely and saw that the shaft broke directly and the arrow was inserted into the tree trunk several centimeters.

"Xiao Mo, this bow is too fierce!" Shi Wu said in shock. He followed what Mo Mo said. When he first pulled, he felt that the force was similar to his big bow, but the more he pulled, the more effort it was. When he pressed the sight, he felt that the arrow speed was faster and the accuracy was much higher than his big bow.

The system gives the reason for the arrow shaft to break, because the arrow shaft has poor straightness and many cracks, so the material has poor rigidity.

Mo Mo sighed and said, "The quality of the arrow shaft is poor. If it is pulled full, it will probably explode. It must be a thicker point or smooth point. There must be no defects inside the arrow shaft, otherwise it will hurt people." There are many problems with the arrow shaft, but fortunately there is no problem with the bow.

Next, Shi Wu shot several more rounds, all of which were half full bows. Although there were no arrows on the shaft, they were also at the critical point.

Mo Mo explained the problems existing in the bow to the carpenter according to the systematic analysis, asked them to optimize the bow, and then produced several sets first. As for the arrows, they could only thicken the arrow shaft and must be made according to the process requirements.

Mo Mo probably had to wait for several days to make several sets of bows. If he cut down new wood to make bow pieces, he had to wait for half a year.

Thinking of this, Mo Mo suggested that Uncle Wu ask people to cut more trees for later use. Maybe in urgent use, they will not be able to catch up.

If you train archery techniques, the power of the compound bow is too great and you are afraid that the arrow will hurt people, so the arrow cannot be reused, and a large number of arrows are needed. The efficiency will be too slow by relying on human processing alone. In addition, the arrows must also be made of iron.

Therefore, the productivity of machining arrow shafts is also a major problem.

The more Mo Mo thought about it, the more worried he became. His tender little face was not a little happy. He felt that the development of another world was too difficult and not as smooth as he imagined.

Alas, let’s do this for the time being, step by step, it’s useless to be anxious.

It’s all those novels misled him. If he figured out this, his face would be much more relaxed.

Mo Mo returned to the earth, had a restful sleep, woke up early in the morning, and his worries were gone.

In the following days, practicing piano, martial arts, dancing, exploring bows and arrows and military affairs became Mo Mo's daily examples.

By the end of November, after repeated improvements, the carpenters finally produced twenty qualified composite bows and three hundred arrows.

Nowadays, the number of carpenters has increased to thirty, but the efficiency of making arrow shafts is still low and not enough for training.

Mo Mo performed his third medicinal bath on December 5th. His combat power has reached 35 points, and his jerk is 36 kilograms, which is comparable to the physical fitness of an ordinary adult. He is a little monster. In a few months, he has developed six-pack abdominal muscles.

When he breaks through 30 combat power, his mental strength reaches 20, and he can recover 20 points of mental energy every day. He will no longer worry about mental energy issues for the time being.

However, the space size cannot be upgraded. System analysis may require more than 100 combat power to be upgraded, and perhaps even higher. He needs a stronger body to resist the mental backlash caused by the expansion of space.

During this period, a major event also happened in China. On November 20, 2008, the country released information to invest 4 trillion yuan to expand domestic demand.

Mo Mo knew that the era of sharp rise in housing prices was coming!
