Earth, Gaochao Village.

Mo Mo came back from the other world and went back to bed to catch up on sleep.

When he got up in the morning, Mo Mo asked his cousin to drive him to the town to buy things.

In the hardware store, there are carpentry tools, measuring tools, drilling tools, rivets, steel nails and screws, all the tools involved in making composite bows, Mo Mo can take through the other world, and he bought three sets.

I can't figure out the number of my cousin's paths, thinking that he is going to repair some toys, and sometimes I feel that he is so inexplicably strange that he has become accustomed to it.

Mo Mo purchased tools and returned home, from the military composite pantograph online store, and told the online store owner about the specific requirements of composite bow parts, and customized hundreds of sets of eccentric wheels, axle sets, spreaders and bow shock absorbers and other components at a high price, requiring all materials to be made of high-strength steel.

The owner of the online store also said that the number of pounds is too large, and it doesn't take such a big pound to kill an elephant, and people can't pull it. Momo explained that composite bows are used for mechanical tensile tests, and there is not much else to explain.

When the owner of the online store encounters a local tyrant player, he can only customize it according to Mo Mo's requirements, and he is afraid that he will ask too much, and the local tyrant will be unhappy and cancel the order.

When it was evening again, Mo Mo moved the tools he had bought this morning to the Atlas and taught the carpenter how to use the newly purchased tools.

Compound bows don't come out that quickly.

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

In the evening, he practiced pulley;

In the evenings, he practiced dancing;

In the early hours of the morning, if he is free, he will go to the other world.

During this time, Mr. Lu, who teaches piano, also went to Mo Mo's house several times, saw that Mo Mo's piano level improved rapidly, and 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 days later.

Heavenly Spirit Continent.

The carpenters have already made several sets of models, and although there are measuring tools, there are still many things that the carpenters have made for the first time.

Mo Mo asked the carpenter to repair and modify, grind and rub, and finally make parts that meet the model standards.

Watching the carpenter retest the data, he was a little entangled, and Mo Mo finally figured out the reason.

He did not give the allowable dimensional error (allowable range of dimensions), and some parts were made too precisely, which was really unnecessary, wasting time, and so inefficient;

The accuracy of some parts does not meet the requirements, such as the production error of the upper bow piece and the lower bow piece is too large, and when the bow is drawn, the force on the bow body is uneven, and the shooting accuracy is of course poor.

After seeing that the workers were basically familiar with the use of tools and the structure of the compound bow, Mo Mo instructed them to start making the parts of the compound bow.

A few days later, Mo Mo received a set of custom composite bow prototype parts from the Internet. Satisfied with the trial production, Mo Mo asked the owner of the online store to order the processing plant to mass production.

Mo Mo transferred the goods to the Atlas and had the carpenters assemble them, and it didn't take long for them to assemble a composite bow.

Although the compound bow is not as good as it should be, it is much worse than the drawing requirements, but it can still be used to test the arrow.

Everyone came to the outside of the workshop to watch Shi Wu test the arrow.

Shi Wu didn't dare to draw a full bow, and he was really afraid of exploding arrows.

Holding the bow in his left hand and holding the arrow in his right hand, he gently pulls the placer, and after the bow is half full, aim and release.

Sou...... Burst!

The arrow was like light, straight into the trunk of the tree fifty meters away, and the arrow shaft "clanged" and broke directly.

"Muzzle velocity 51 m/s, feather weight 120 grams, kinetic energy E = 1/2 mv2 = 156 joules, energy weakening at 50 meters away,......" The system quickly measured the shooting data.

Mo Mo got this data, which was expected.

The amount of energy required to shoot through an adult male's ribcage is around 74 joules, and the new compound bow is no longer a problem at all.

Like Earth's top-of-the-line compound bow, the arrow can shoot with a kinetic energy of 160 joules, which can easily kill an elephant.

A few people took a closer look, and the shaft of the arrow was directly broken, and the arrow was inserted into the trunk of the tree several centimeters.

"Xiaomo, this bow is too fierce!" Shi Wu said in shock, he followed Mo Mo's operation, and when he first pulled it, he felt that the force was about the same as his big bow, but the more he pulled, the more effortless it was, and when he pressed the sight, he felt that the speed of the arrow was faster, and the accuracy was much higher than that of his big bow.

The arrow shaft is broken, and the system gives the reason, and the straightness of the arrow shaft is poor and there are many cracks, so the material rigidity is poor.

Mo Mo sighed and said: "The quality of the arrow shaft is poor, if it is full, it is estimated that the arrow will explode, it must be made thicker and smoother, and there can be no defects inside the arrow shaft, or it will not hurt people." "There are a lot of problems with the shaft, but fortunately there is nothing wrong with the bow.

Next, Shi Wu shot a few more rounds, all of which were half-full bows, although the shaft of the arrow did not explode the arrow, but it was also at the critical point.

According to the systematic analysis, Mo Mo explained the problems of the bow to the carpenter, asked them to optimize the bow, and then produced a few sets first. As for the arrows, they can only be thickened, and they must be made in accordance with the process requirements.

Mo Mo estimated that it would take a few days to make several sets of bows, and if he cut down new wood to make bow pieces, he would have to wait half a year.

Thinking of this, Mo Mo suggested that Uncle Wu ask someone to cut down more trees for later use, maybe when it was urgent, he wouldn't be able to catch up.

If you train archery, the compound bow is too powerful, and you are afraid that the arrows will hurt people, and the arrows cannot be reused, so you need a large number of arrows, and the efficiency is too slow to rely on manual processing. In addition, the arrowheads had to be made of iron.

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

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

Hey, let's do this for the time being, step by step, it's useless to rush.

It's numb, it's all those novels that misled him, and when he figured it out, his face was much more relaxed.

Mo Mo returned to Earth, made up for sleep, and woke up early in the morning, his troubles gone.

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

By the end of November, the carpenters had made twenty qualified composite bows and three hundred arrows.

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

Mo Mo took the third medicinal bath on December 5th, and his combat power has reached 35 points, and his clean and jerk is 36 kilograms, which is comparable to the physical fitness of ordinary adults.

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

It's just that the size of the space can't be upgraded yet, and the system analysis may require more than 100 combat power to upgrade, maybe even higher. He needed a stronger body to resist the mental backlash caused by the expansion of space.

During this time, a major event also happened in the country, on November 20, 08, the state released information that it would invest 4 trillion to expand domestic demand.

Mo Mo knows that the era of soaring housing prices is coming!

In this life, he didn't want to miss flipping houses again.

He wants to buy a large number of houses, so let others envy and envy them.

When you are tired of flipping houses, you can play some meaningful business.

Flipping a house, after all, is not the right way, and people can't live just for money.
