Chapter 1230: Shadow of Saltpeter (2 in 1)

Han Younan took the people and left from the Hualian tribe. Before leaving, he gave the Hualian tribe a jar full of salt instead of the half jar at the beginning.
　　 It can be seen that this person was really shocked by the big secret of the Hualian tribe this time.
The leader of the 　　 Hualian tribe, holding a heavy jar of salt in his arms, watching Han Younan and others who were going all the way with the crisp copper bell, his face couldn't help but burst into a bright smile.
　　 This time, relying on the big secrets of his tribe, he not only obtained great psychological satisfaction, but also earned face in front of the Qingque tribe, but also obtained extremely practical things.
　　 Apart from the rest, the salt in this jar alone is extremely precious!
　　According to the information he received, when the surrounding tribes exchanged salt from the Qingque tribe, they all used spoons. How could they be like their own tribe, and they only used jars?
　　 This jar of table salt, but my tribe got it for nothing.
　　 As for whether his tribe will suffer any loss after exposing the big secrets of his tribe, the leader of the Hualian tribe doesn't think there will be any.
　　 Because this big secret has always been in my tribe, no one can take it away.
　　 After all, this is not something human can do.
　　 If that is the case, why not use this big secret of your own tribe to open your face to the tribe and shock the people of the Qingque tribe, and then use it to exchange something for your tribe for free?
　　 Still the same sentence, because of the particularity of this big secret of my own tribe, and this big secret of my own tribe, I am afraid that others will know it from time to time.
　　Because even if it is known to the rest of the people, they have no way to remove this big secret of their tribe from their tribe...
　　 With such a good mood, he stood there holding the salt jar for a while, and waited until no one could see the Qingque tribe, the leader of the Hualian tribe, then turned and walked towards the cave.
　　 After putting the jar of easy salt carefully away, let the people in the tribe and then begin to deal with the sheep that they can get.
　　 Some sheep have been smashed beyond recognition, and some places are directly bloody, so it is not easy to deal with.
Except for some of the treated sheep that were left outside for short-term consumption by the Hualian tribe, the rest were arranged by the Hualian tribe leader, and the Hualian tribe’s people were given the secret of their tribe. For storage.
　　 Some sheep that were put in early are already frozen...
　　Han Younan led the team on the road, and couldn’t help but talked with the people in the team about what he saw in the Hualian tribe, and was amazed by it.
　　 was amazed by the wonders of the various things in this world.
　　 During the discussion, many people in the team couldn't help but say, if their tribe had such a place, it would be great.
　　 This is not only convenient for storing food, when the summer weather is hot, get some fruits and other things in it, and wait until it gets cold before taking it out to eat, it should be so comfortable!
　　 Just a little thought can understand that the fruits produced in this way must be more delicious than those soaked in the well water!
　　 Of course, I was surprised and surprised by such things in my heart, but Han Younan did not directly bring people back to the tribe, telling these things to the people in the tribe.
　　 After all, his main task is to take people from the tribe and exchange with the surrounding tribes.
　　 And now, the things he brought with him this time have not been exchanged yet. Under such circumstances, of course he is reluctant to return to the tribe.
　　 And this thing is strange, but it cannot be copied or transferred to one's own tribe.
　　 In such a situation, it is really important not to continue the exchange that I should have done.
　　 Thinking like this in his heart, Han Younan led the team and headed towards the rest of the tribe, continuing the exchange...
　　 In the Tieshan residential area, Han Cheng also explained something to the second brother, and waited here for nearly 20 days. After a lot of iron pots were produced here, he led the team to leave.
　　 Those who were brought by him who belonged to the Stone Tribe and the Pine Tribe, this time Han Cheng did not bring them back, leaving them scattered among the three tribes.
　　 Then he added an equal number of people in three places, took them along, and prepared to bring them from the three tribes in the south to the several tribes in the north.
　　 is used to split on the one hand, and on the other hand, there are also some people who were originally brought from the north by Han Cheng. After such a long time, they want to return to the northern tribes.
　　 Not to mention living for a long time, even if I lived in the main tribe for some time and wandered back and forth, I felt comfortable in my heart.
　　 Han Cheng knows the thoughts of these people very well.
　　 Don't look at them. At this time, they always think of the northern tribes and want to return to the northern tribes.
　　 In fact, they did not allow them to return to the tribes to the north to live for a while. If they waited for a long time, they would miss the tribes in the south.
　　 After all, after living in these tribes in the south for such a long time, they have gradually taken root here, leaving behind a lot of thoughts.
Han Cheng took the people and set off from here. In the whole team, except for the food and some fodder for feeding the animals on the way from Tieshan Residence to Jinguan City, the rest are basically ironware. !
　　 And among these ironware, iron pots are the main ones.
　　 Han Cheng waited for more than 20 days in the Tieshan residential area before he set off, leaving from the Tieshan residential area, just to wait for these iron pots.
　　 On the road from Tieshan residential area to Jinguan City, although people traveling back and forth over the years have had a small range of rest during the walking process, it still seems difficult to walk on the whole.
　　 The son Han Da, who has a lot of road construction experience and is familiar with the benefits of road construction, naturally thought of road construction.
　　 Jinguan City has already been developed, and there is sufficient food, so now, it can be done by people.
　　Thinking in his heart, Han Cheng was walking on the way, so he made a decision to wait until he returned to Jinguan City to start arranging this matter.
　　 You don’t need to be too anxious about this matter, you can use fewer manpower, fewer tribes, and start small and build slowly.
　　Wait until the autumn harvest of several tribes here in the autumn is completed and enough food is obtained, then more people will be deployed and hired to speed up this matter...
　　While walking, thinking in his heart, Han Cheng led the team all the way to Jinguan City.
　　 After coming here, I must have a rest here, otherwise it is not so good for the mountain that lies across there.
　　 Han Cheng also took advantage of this opportunity to talk to the long legs who stayed here in charge of the overall situation about his thoughts on road construction.
　　 Then quickly based on past experience and the specific situation of Jinguancheng, a specific implementation charter was worked out here.
　　 After six days, when Han Cheng took the rested team and set off from Jinguan City to the main tribe, the Jinguan Railway here in Jinguan City had already begun small-scale construction.
Of course, in addition to many reasons, the reason why construction can be started so quickly is that the direction of the Jinguan Railway is along this line that has already been trampled out from Jinguancheng to the railway. The road from the mountain residential area was not carried out separately to open a new route to build this road.
The team led by Han Cheng had some changes when they set off this time. The biggest change was that they carried some iron pots, which were left here by Han Cheng, so that the people in Jinguan City could also experience it. To the use of wok.
　　 The donkeys and other animals that were left vacant by unloading the iron pan, as well as people, are also idle, but they are carrying things like food.
　　 This is for eating on the road.
　　 After finishing these things, the son of Han Da had no nostalgia. He waved his hand and led people out of Jinguan City, towards the main tribe.
After walking three or four miles, Han Cheng ran into the trade team that had always been affiliated with Jinguan City. The leader of the team was to replace all the salt and pottery he carried with them and then returned to Jinguan. Han Yunan in the city.
　　 Seeing Han Younan leading the people back, Han Cheng also felt happy.
　　 After all, this Han Younan is an old man in the tribe, and there are also some old hands in the tribe in the team he leads. After seeing it, he feels kind.
　　 Under such circumstances, I naturally feel happy.
　　Han Younan is also particularly happy to be able to meet the son of God here at this time.
　　 After all, the Son of God is so respected and loved by others. It is enough for people to feel happy just to be able to meet and talk to the Son of God.
　　 Not to mention that this time I and others were still in the Hualian tribe and saw such a magical thing!
　　Han Younan's idea of ​​what the big secret of the Hualian tribe was the first time he saw it was that he should tell the matter to the son of God, and it is best to be able to tell the son of God himself.
　　 After all, the son of God is so kind and respected, and still so knowledgeable.
　　 And now, I just came back from the outside with someone, before I arrived at Jinguan City, I met the son of God here.
　　This situation, how can you keep Han Younan happy?
　　Meeting, and after speaking for a while, Han Younan was full of excitement and began to talk to Han Cheng, a respected god, about the big secret of the Hualian tribe he saw in the Hualian tribe...
　　 Just as Han Younan had expected before, even if he was smart, wise and knowledgeable as a son of God, he suddenly heard what he said about this magical place at this time, and it was unavoidable for a while.
　　 So I said that I was in the Hualian tribe before, and under the leadership of the Hualian tribe leader, I saw the big secrets of the Hualian tribe, and the surprised reaction that my mouth couldn't close together was very normal and not shameful.
　　 After all, with Shenzi’s wise martial arts, just listening to him say this, it became like this...
　　 There is nothing wrong with what Han Younan thought in his heart. Han Cheng, the son of the Qingque tribe, is truly shaking at this moment!
　　The reason is precisely because of the big secret of the Hualian tribe that Han Younan said.
　　 But it is a little different from what Han Younan thought in his heart, and there are deeper reasons.
　　 There is only one thing in Han Cheng's mind at this moment, and that thing is saltpeter!
　　 As a posterity, Han Cheng knew some of the conditions of freezing.
　　 If you want water to freeze, the fundamental way is to let the temperature drop below zero.
　　 Under natural conditions, the root cause of the temperature drop is nothing more than the distance from the direct sun, the invasion of cold air mass, and the higher the latitude, the lower the temperature, the higher the altitude, the lower the temperature...
　　 Obviously, Han Younan’s big secret of the Hualian tribe does not meet these conditions.
　　 are located in the northern hemisphere. The Hualian tribe is located farther south than Jinguancheng, and has a lower latitude.
　　The cave in which the tribe lives is not located on the top of the mountain, so in principle, it will not freeze.
　　 But in the cave behind their cave, thick ice formed at this moment!
Under such circumstances ~EbookFREE.me~ Faced with such special things, Han Sung, who has been anxious to get angry because his tribe cannot find saltpeter and cannot produce gunpowder for a while, first In time, this situation was linked to saltpeter.
　　 Benefiting from the messy things I have seen before crossing, as well as some weird knowledge obtained in classrooms and forums, Han Cheng knows some characteristics of saltpeter.
One of the most impressive is that the travellers poured saltpetre into a water tank and used saltpetre to turn the water into ice. This made it easy to obtain ice in the summer, making an exceptionally precious cold drink, which caused waves of wonder. And get many benefits by the way.
So after listening to what Han Younan said, and quickly eliminated some conditions, and under his inquiry, he confirmed from Han Younan that there was indeed water in the cave, Han Cheng’s My heart couldn't help but jumped up, very violently, beating the drum!
　　 In addition to this reason, Han Cheng really couldn't think of other reasons, such a special existence formed in the cave of the Hualian tribe!
　　 "Return to Jinguan City! Return to Jinguan City! We will not return to the main tribe for the time being!"
　　 After having a conversation with Han Younan, his heartbeat speeded up, and Han Cheng, who was a little dry, did not hesitate to give such an order promptly!
　　 Although everyone was a little dazed for a while, they still did so according to the request of the son Han Cheng...
