I Killed the Dragon

　　 Thinking of the scene where he explained the toilet to the people in the territory at first, Gray sighed slightly, and didn't mention any punishment or punishment. Now let's teach this guy what a toilet is.

This also has its own problems. I thought the toilet was such a good thing. As long as I invented it by myself, everyone would know it and be imitated by people all over the country. But this is not the case. Up to now, there are people in his original territory. Remember and use.

　　Other places, except for a few businessmen, no one knew the term toilet, let alone imitated it.

　　 They are used to solving problems at will, letting them solve the problem in a fixed place, as if it violated their nature.

　　 After a few seconds of silence, Gray kicked the rock in front of him with his toes, "Come with me, I will tell you what a toilet is."

　　 After finishing speaking, he did not choose to go over the construction site again, but walked around the cliff.

　　Walking on the edge of the cliff, Gray looked at the sea five or six meters below, and thought that maybe he could build a stone step here, and when he was interested, he could go swimming or fishing.

　　 But it is not in a hurry. It is not difficult to hit a stone step. The big deal is that when you take the sword in the lake yourself, with the sharpness of the sword in the lake, you should be able to cut a beautiful stone step soon.

　　 led a group of people quickly around to the location of the air outlet on the construction site, and could no longer smell the pungent smell.

　　 "Bring a few shovel here, and then bring a plank." Gray said to the soldier behind him.

　　 The two soldiers nodded and went to the construction site to find shovel and planks.

　　 "Let's talk about it, what problem you have encountered." It will take a while for them to come back. Gray didn't plan to just wait and waste time like this, and sat down on a piece of yellow grass.

"You know, the adhesives we used in the past were all **** from the binding tree, but your newly proposed adhesives made of fired limestone, clay, iron ore and other materials are indeed It’s better than before. At present, we have begun to manufacture this adhesive in large quantities. This can also become an industry of the royal family in the future, and..."

　　 Frado carefully sat some distance away from Gray, slowly reporting the progress of these days, and finally made a proposal that was beneficial to the royal family.

　　 But it doesn’t need to be said by him. Gray had thought of it a long time ago, but he never thought of developing it into an industry.

Because the iron ore here is really scarce, he doesn’t have that much iron ore to make cement. In addition to his own castle, even the walls of the new king’s city must use the old binder, not to mention other nobles. Up.

In fact, compared with cement, the previous adhesive is not much different. It is probably the difference between nine and ten. This is mainly because a kind of adhesive tree that is very similar to the previous rubber tree. This kind of tree can produce one. This kind of mucilage, after adding other materials, will quickly dry and become a natural adhesive.

　　 "Just talk about the problem, I'm too lazy to deal with the preparation of the castle, anyway, if there is a problem with the castle in the future, I will find you." Gray interrupted his narration and said directly.

Frodo stopped the topic with a bitter smile, pinched a weed in his palm and swiped it unconsciously, and thought for a while: "There are not many problems. I can probably solve small problems, but you said that you use gravel and cement. We have also found a suitable ratio for mixing into concrete, but there is not enough gravel and it is difficult to manufacture in large quantities."

When Gray heard this, he also understood what was going on. The gravel here basically relies on manpower to smash with a hammer, and in the worlds he has been in so far, gravel is basically broken by machines. .

　　 Compared with manpower and machines, the gap is naturally huge.

　　 He can't do anything about this at the moment. He can't get the stone crusher for the time being, so he has to find some material to replace it. You can't all the gravel to be beaten manually. How much manpower does that cost?

　　Or there is no stone crusher, can I develop one by myself?

　　 Gray thought for a while, took out a short sword and began to draw on the ground.

His idea is to cast a huge iron block, then use a machine to hoist it, and then smash it down fiercely, so that the stone should be smashed, several times, and it is not difficult to get fine stones. Come out a simple stone crusher.

　　 Gray first drew a machine that was hoisted by pulleys, and then shook his head. Such a machine is too complicated. With the current technology, it is impossible to make it in a short time.

　　 Then he thought for a while, remembering the kind of tool that he used to pound chili with his grandmother when he was young in his previous life. Using the principle of leverage, he could pound the dried chili from the other end into chili powder by stepping on one end with his foot.

　　 He forgot what this tool was called, but the principle is very simple.

He drew a bracket on the ground, and put a huge wooden pole on it. One end of the wooden pole dropped a huge iron block, and the other end was a rope. People can pull the rope, and a few people can easily pull the big iron block. Pull it up, then release it immediately, and the big iron can hit the rock below.

　　 "This is feasible." Gray thought about it in his head, and felt that even if there were difficulties, it would not be too difficult and the degree of feasibility was high.

　　The soldiers came back with a shovel and a plank. Gray did not rush to ask them to dig a pit to build a toilet. Instead, he picked up a shovel and a plank to explain the principle of leverage to Frodo.

　　 Gray dug a shovel of soil with a shovel, and then placed it on the horizontal plank, changing the ratio of the two ends. He didn't talk about the principle of leverage, but just told him how to save effort.

　　Frado is not stupid. Combined with Gray's explanation, he quickly understood the function of the tool Gray drew, and immediately offered it another flattery.

　　 "Okay, the gravel problem is solved, then let's talk about the toilet problem."

　　 Gray got up from the ground and commanded two soldiers to dig a hole in the ground, then put a wooden board on it, and a simple toilet was completed.

"Of course, the real toilet needs to be dug deeper and bigger to make it easier for everyone to use the toilet. The entire construction site will not be so smelly. You can also use wooden boards to block it with tiles and weeds. UU Reading www.uukanshu.com It won’t be seen."

　　 "Your Majesty, I am deeply impressed by your wisdom." Although he didn't quite understand it, it didn't affect his flattery.

"You tell the workers the benefits of being in the toilet, so that each of them must be in the toilet. If they are not obedient, their salary will be deducted and his workload will increase." Gray snorted coldly. He didn't want to move into a new one in the future. When I was in the castle, there was still a smell of feces and urine.

　　 "Yes, I must have someone build a toilet immediately and convey your will to them."

To solve the problem here, Gray was about to take the people away. Suddenly he thought of something and looked back at Frodo and said, "Isn't there a river not far away? The sand in the river can be sifted with a fishing net. sand."

　　 "Your Majesty, the mesh of the fishing net is so big, how can you get fine sand?" Frodo asked carefully.

　　 Gray was taken aback. This is because the technical level here is not enough. The nets of the fishing nets are not small. The smallest ones are as big as the thumbs. The sifted sand is really not fine sand.

　　 "Then use the first method. I will let them try to weave a finer mesh. If it can be done, I will give it to you first."

　　 "Your Majesty, I'm so stupid. I didn't expect that there is a lot of fine sand on the beach?" Frodo said with a smile on his face, and he liked his thoughts.

　　 His Majesty the King’s face became cold, but he knew that many tofu dregs projects in the past were due to misuse or private use of sea sand, which is not suitable for construction.

　　 told him that sea sand was not suitable for construction, but Frodo was dubious.

　　 Gray warned Frado directly and severely, and explained that if he knew that he used sea sand, he would kill him directly, so that he was so scared that he vowed not to use sea sand, and then left.
