Slanting his head and looking at the "loot" rolling down the door, Jiang Yu'er did not regret this risky action, "support the bold to death, starve the cowardly", and if you don't take the risk, you can still soak boiled water in black cakes now, what about a month later? Boiled water soaked in boiled water?

Conformism means starving to death for her now, the Jindan ancestor who starved to death? I'm afraid it's really the biggest joke in history.

Doing nothing to repeat the new hobby these days, staring at the ceiling, staring at the staring, people laughed silently, laughing and laughing and tears remained, hot tears fell on the cold floor, Jiang Yu'er closed his eyes, opened them, and returned to expressionlessness.

You can't be vulnerable, you are only allowed to cry once.

Because you are already an adult, the world of adults is inherently cruel, whether before or after the end.

Because I'm not sure if I'm being watched, this time Jiang Yu'er is simply low-key and can't be more low-key, even eating is hiding in the quilt, trying not to make a sound, half a month later, the bean sprouts grew into mung bean seedlings, and the potatoes also climbed the wall, Jiang Yu'er finally opened a small corner, and secretly looked out, and there was a zombie standing outside the windowsill.

Seeing that the curtain was opened, the zombie tilted his head and grinned, this time it almost scared Jiang Yu'er out of the shadow in his heart.

My Mom!! Death, this is!!

After laughing, he pulled out of his coat pocket and pulled it out for a long time, took out half of the rotten cecum and threw it on the windowsill, and walked away again...... Needless to say, it's the slanted eyes and crooked nose! Jiang Yu'er really wanted to kill this stupid zombie with a knife, but she couldn't, the patience period of high-level zombies is generally three months to half a year, and they must have sent their younger brother to keep an eye on it, at least a second-order with a certain amount of wisdom.

It seems that this curtain really can't be lifted recently......

Sitting on the ground decadently, since he didn't feel the creepy coldness just now, those third-order and fourth-order zombies should have left, and the second-order zombies are not so smart, as long as they don't show their heads, they should be fine, so they breathed a sigh of relief when they thought about it, and only then did they dare to sort out the materials collected half a month ago.

With the bottled water, Jiangyu can finally say goodbye to the turbid old water with tears, and the oil, salt, sauce and vinegar are now available, and even four or five lighters and a small box of alcohol cubes are collected, which means that you can eat a mouthful of hot food, but unfortunately the alcohol stove was forced to give up because it could not be stuffed, and the kitchen knife on the machete was also replaced by the German Zwilling again.

In addition to the first instant noodle mustard, I also found half a carton of milk downstairs, about two catties of pickled cabbage, five ham sausages, a few catties of nuts and fruit cakes and candies, two bags of dried noodles, dried fish and bacon sausages about five or six catties, a package of dried persimmons, a can of milk powder, two bags of cereal, four bottles of large bottles of drinks, three boxes of chocolate, six bottles of mineral water, some household fever and cold medicines, etc.

The river fish that entered Jindan is basically the same as the word cold Saybey, but like amoxicillin, aminophen xanemia, acetylcysteine, norfloxacin, cefaclor, ampicillin sodium, etc., are good things with no price in the base, and in the past two years, the big base has begun to establish a pharmaceutical factory to re-pharmaceutical, but unfortunately there are countless people who are injured and sick every day, and there are many monks and less porridge, and even iodine wine is specially used, not to mention antibiotics, and the supernatural can only buy a small amount according to the level, as for ordinary people? There is no eligibility to purchase at all.

Sort out the things and put them in the cabinet, and the heart is indescribably satisfied, although almost all of the things in it are expired, and some even have ants, but the river fish is not too demanding, compared with the black cakes, these are the delicacies of the mountains and the sea.

After reading "One Hundred Thousand Whys", "The Unsolved Mysteries of the Earth", "Iron Will", and "The Merry History of Emperor Kangxi" in the room for the fourth time, Jiang Yuer decided to find something to do by herself.

For example, to make a crossbow.

The idea was that there were plenty of raw materials, and the furniture in the house was made of solid wood, not compressed boards, and there were only four bullets, so even if they left in two months, it was time to prepare.

The idea of making a crossbow is also the first time to catch a duck on the shelf, and the rise of this idea is mainly because the "History of the Kangxi Emperor's Merry" mentions that the grassland woman Xiangxiang made a crossbow to protect herself, and it is very powerful to wear Yang in 100 steps, and the production method is mentioned in detail above.

Jiang Yu'er drew a scoop according to the gourd, and began to make a crossbow, first of all, as the main material of the bow must be tough, the mulberry dresser was requisitioned, and a first layer of cowhide coat was dismantled and carefully wrapped around the bow stem, so that the elasticity is doubled, and more power can be accumulated and shot farther.

The composite bow trunk with mulberry wood as the core and cowhide wrapped around it combines the elasticity of plants and animals in nature, and the two materials are truly integrated after the wood stamen and leather strips are impregnated with paint. The elasticity is greatly increased, and the power is not reduced even on rainy days.

Then there is the production of wooden arms, which are generally 60~75 cm long and 4~5 cm wide. There is a closure at the front end. The upper lip is short and the lower lip is long, just in place to embed the bow. Then tie it with cowhide, add the almighty 502 fixation, and tie it back to the ears on both sides of the wooden arm, so that the bow and the arm are tightly knit, and the reaction force and vibration when the bow is pulled and the arrow is shot cannot be loosened. The crossbow arm has a concave arrow path, which can hold the arrow and increase the surface contact area with the arrow, increasing the firing resistance. However, the arrow path can effectively fix the position of the arrow cluster on the crossbow arm, improve the accuracy, and prevent the firing failure caused by the venting string. So a little bit of added resistance doesn't matter.

Finally, the rear of the crossbow arm was fitted with a firing sight device, which was a set of components that required precision casting. It is composed of a lookout mountain, a hanging knife, and a cow. The conditions were limited, so Jiang Yuer dug a wall, made a simple boiler out of red bricks, and put several stainless steel pots in it to melt and forge little by little.

Lookout is an aiming device; The suspension knife is also the trigger.; Cows are the most elaborate objects of design. The tooth is connected to the hanging knife, but does not directly bear the force, but is pivoted by the ox. When winding, the crossbowman pulls the string against the Wangshan, the Wangshan moves back, and the ox resets after the teeth are in position. The ox bears the tooth force on the top, and the hanging knife is against the knife, and the bow and crossbow enter the state of preparation. If the crossbow is fired, the process is exactly the opposite of winding. The crossbow wrenched the hanging knife, and the ox sank even more as soon as it was loosened. The teeth had no support, and the force sank, and the bowstring flew away with arrows. This sophisticated design greatly improves the reliability of projection, greatly reduces the false firing rate, and reduces the vibration during firing, which can greatly improve the shooting hit rate.

The whole process is really difficult only to melt stainless steel pots! Jiang Yu'er burned for four days to get enough molten steel, because during this time of beating and burning, the walls of the house turned from white to yellow, to black and black.
