In the early morning, more than 20 soldiers who participated in the construction with bloodshot eyes finally completed the final process. They were tired enough, but when they saw the giant waterwheel they had built, they felt a sense of pride and satisfaction.

The whole watermill is two people tall. Each of the four wheels alone is nearly a man tall. The body is two feet long and one foot wide. The height of the oval-shaped water tank on the heavy disc is also close to a foot. The entire surface of the water container is tightly tightened with a thinly sliced iron hoop, and it will never fall apart because it is filled with water. The whole cart stood like a chubby monster in the morning light, which made people feel incredible.

It's not over yet, the watermill has been built, but it hasn't been tested yet. Whether it will be really practical or if it will collapse into pieces as soon as it is started, no one knows. Everything has yet to be tested.

Some of the soldiers in the entire garrison of the defense force have one more training content today, that is, filling water into the water wheel. A few soldiers pushed the water cart to the well in the south corner of the church, and seven or eight soldiers began to take turns to draw water from the well, and then pass it to the people standing above the water tank, and poured buckets into it. There was some leakage in the tank, but it wasn't serious, just water seepage at the interface. This problem will be solved quickly, because the parts of the wood will quickly become more tightly packed after being wetted, and the internal water pressure will also press the gum used to fill the gap more tightly into the gap between the thick boards, so this is not a big problem at all.

Bucket after bucket, bucket after bucket, the whole container was filled with more than 380 buckets of water before it was filled with water.

"Alright, let's get the leather tube ready." Fang Zi'an commanded in a deep voice.

A leather tube the thickness of an arm's arm that had been cut by a large amount of water bladders in the warehouse was dragged. Although the length is only seven or eight zhang long, it is more than enough for testing. Li Dalong followed Fang Zi'an's instructions and put one end of the leather bag on the log outlet flowing from under the water tank. The four small holes on the cut and sewn leather bag are respectively placed on the wooden handle specially set aside at the water outlet, so as to ensure that the skin can be firmly fixed to the water outlet and firmly put on it.

"Brother Fat Tiger, ready. I'm going to open the floodgates. Li Dalong said.

Lei Hu squatted down from the horse with the front section of the leather pipe and said, "Come on, I'm ready." ”

All the soldiers around looked at all this with anticipation and curiosity, they didn't know if it was useful for Lord Fang to build this thing for two days and one night.

Li Dalong looked at Fang Zi'an, and Fang Zi'an nodded. Li Dalong reached over and slowly turned the gate wrench of the water outlet. There was a loud purring sound, and the leather tube on the spout was originally lying on the ground like a skin snake, but in an instant, it swelled and thickened like a python that had been injected into the soul. The water in the skin tube can be seen rushing forward with great speed. The next moment, a stream of water rushed out from the front of the water pipe held by Lei Hu, and it was extremely fierce.

Lei Hu laughed and hugged his skin bag and raised it, and a column of water rushed diagonally three feet away, impacting a low tree, and scattering the branches and leaves. A large amount of water is poured out in an instant. If there is a fire there, it will be extinguished in an instant.

"It worked, hahaha. It's so strong. It can be sprayed up to three or four feet away. ”

"Good guy, this thing is amazing, and it will be much easier to fight fires in the future."

"Yes, this one is poured on, and any fire is extinguished."

The crowd erupted in cheers and laughter, and they all pointed their fingers at each other. The soldiers who had worked all night also cheered, and finally their hard work was not in vain.

Fang Zi'an was not too happy, the leather pipe was a little leaking, the surrounding water mist was splashing, and the leather pipe needed to be specially made, otherwise it would affect the water pressure and waste water. But this is not the point, this is just the most basic test, what Fang Zi'an wants is to design the height of the water tank, and the test that can greatly exert the power of the water wheel water dragon has not yet begun, and that is the ultimate goal to achieve.

"Close the floodgates, refill the water, and continue testing." Fang Zi'an shouted.

Lee Dalong hurriedly closed the floodgates, and the soldiers began to replenish the lost water. This time, the tank was quickly filled. The ten strong soldiers arranged by Fang Zi'an were already in position on both sides of the waterwheel, and two huge round winches with wooden handles were mounted on the spiral shafts on both sides.

"Are you ready?" Fang Zi'an drank.

"Ready, sir." Ten soldiers replied loudly.

"Okay, let's go!" Fang Zi'an ordered loudly. Ten soldiers began to drive the winches on both sides at the same time, and the winches drove the horizontal spiral iron shafts to start turning. The groove of the thread clenched tightly to the iron shaft standing upright in the middle, and it was still slowly pushed up. There was a screeching sound where the threads were biting, and the sound was so harsh that it made people count down to the hairs. And because of the great force, there was a spark popping out when it was rubbing.

"Wait a minute." Raised less than half a foot, Fang Zi'an suddenly shouted.

The ten soldiers stopped turning, and the tank fell back, but it was blocked by the rungs on the mesh iron bars that rose from the dead end, and landed steadily on it. This means that the load-bearing grids at the corners and the fallback pins are fine.

"Bring the grease." Fang Zi'an ordered, and a soldier quickly handed over the boiled grease, Fang Zi'an fished a handful, leaned into the gap below, and smeared all the grease into the spiral groove that was biting. Everyone was sweating, if the water tank fell at this moment, Lord Fang was afraid that his head would be crushed.

"Keep going up." Fang Zi'an shouted.

The winch continued to turn, this time the shrill grinding sound seemed to be quieter, but it was still dull and unpleasant. But it was clear that the bite was not as sparkling as the one in the right place. However, the higher it got, the entire device and tank creaked and began to shake slightly. The onlookers were so nervous that they didn't dare to breathe, and their hearts were pounding. In particular, the soldiers who participated in the construction were nervous to death, for fear that they would fall short. This is not only a test of whether the lifting device can work, but also a test of the bearing capacity of the water tank, as well as the precision and firmness of the spiral lift. If the threads don't fit, or if they aren't accurate enough, they fall off, and everything will be ruined.

"Go on, go on, at a constant speed, at a constant speed, don't be quick or slow." Fang Zi'an was also sweating nervously, staring at his eyes and shouting loudly.

Finally, the six- or seven-foot-long spiral iron rods were almost all jacked up, and the entire water tank was also jacked up to a position nearly one person higher than the chassis. And the position from the ground is nearly a foot high. The whole waterwheel shook slightly, making a creaking sound, and seemed to be very unstable. The four wooden wheels were all stuck on both sides of the wheels with wooden wedges before, otherwise they would have begun to roll and overturn due to the change of center of gravity.

"Upper pin, fixed position." Fang Zi'an shouted loudly.

The rotating winch was stuck in position by coarse logs, and the supporting irons at the four corners were almost fully deployed. In the process of stretching all the way, the bayonet is inserted into the iron bar all the way to fix, which completely supports the weight of the water tank at this moment. The entire tank is actually supported by a screw top in the middle and iron mesh at the four corners. Five fulcrums to firmly lock the tank into its current position.

"Brother Leizi, how long did it take?" Fang Zi'an asked Su Lei.

"Brother Fang, it took three hundred and twenty breaths." Su Lei said.

Fang Zi'an smiled and nodded, "It's just tea time." "Three hundred and twenty breaths, about five minutes, can raise the water tank in such a short time, Fang Zi'an is already very satisfied.

"Start testing the water dragon." Fang Zi'an said loudly.

Li Dalong acted immediately, he climbed onto the chassis of the body, saw a row of large, medium and small water outlets under the water tank, and put the leather pipe in his hand on the most suitable water outlet.

"Brother Lei Hu, you have to be careful this time, the water will be stronger." Fang Zi'an reminded.

"Don't worry, I can't catch this hose yet? Brother Dalong, open the floodgates. Lei Hu said loudly.

Li Dalong nodded, stretched out his hand to turn the gate, and in just an instant, a stream of water filled the leather pipe, and the entire leather pipe jumped like a poisonous snake.

"Poof." The water column shot out, high and far, and the force was incomparably strong. Lei Hu obviously underestimated the power of this water column, and the whole person was led back by the backrush, and a soldier hurriedly stepped forward to support it, and the two people hugged the spout tightly, so that they could be regarded as stabilizing their strength.

Everyone watched as the water column erupted seven or eight feet away, directly hitting the wall, impacting the green vines and weeds crawling on the wall. The mud splattered everywhere, and they all applauded loudly.

Fang Zi'an paid close attention to the overall operation of the water wheel, and paid attention to the strength distance and height of the water dragon. The building here is no more than three stories high, and the water jet spewed out by the water dragon can reach a height of five zhang, which is already the roof of a three-story building. The waterwheel test was fully qualified. The next step is just a few minor tweaks. For example, the sewing of water pipes should be more delicate and strong, and water pipes of different thicknesses should be sewn and used according to the fire situation. For the stability of the entire waterwheel chassis, some simple configurations are also required. For example, it is not difficult to fix it with wooden stakes, or to increase the wooden frame that can share the power of the wheels and increase the stable fulcrum.
