It was the spring ploughing season, and the Liu tribe, which was about seven days away from the east of the Xia Kingdom, was in a panic, unintentional spring ploughing, and even their normal life was affected somewhat, all because of the ultimatum issued by the Xia Kingdom to the Liu tribe at the beginning of spring.

After withstanding natural disasters and resisting food wars, the Liu tribe is now only a medium-sized tribe with a population of more than 1,300 people, compared to the strong Xia Kingdom, the strength of the Liu tribe is weak and pitiful, and it is powerless to resist the Xia Kingdom at all.

On that day, Xia Guo issued an ultimatum to the Liu tribe, and the leader, who had always been steady, immediately panicked, he didn't know how to choose, he didn't know whether to lead the tribe to join the Xia country, or move, the leader clearly understood in his heart that the strength of the Liu tribe could not resist the Xia country at all, so the leader didn't think about the third option "war" at all.

The Xia State fleet left, and the leader immediately convened the high-level members of the Liu tribe to discuss the matter, everyone knew the strength of their tribe, and no one mentioned the matter of "war", only discussed in the two options of "joining the Xia Kingdom" and "moving".

In a short period of time, the top level of the Liu tribe was divided into two camps, the "join the Xia Kingdom" camp accounted for nearly one-third of the number, and the "moving" camp accounted for two-thirds of the number, and the leader did not make a choice, he wavered between the two options.

"Our tribe should join the Xia country, we can live a better life by joining the Xia country, and we don't need to worry about food in the future, and we don't need to worry about the enemy's problems, there are already so many tribes joining the Xia country, and there is no problem for our tribe to join the Xia country."

"No, our tribe can't join the Xia country, we should move, find a new home, join the Xia country, there will be no more our tribe in the future, I don't want to join the Xia country, I am a member of the Liu tribe, I am willing to fight for the Liu tribe, not to become a Xia country."

"Moving? If we give up our home for so long and move to a new place, then our tribe will definitely be hit hard, there are too many dangers on the way to move, and even our tribe may be wiped out on the way to move, and our tribe will not be able to move. ”

"Yes, we can't move, choosing war is death, choosing to move is death, we can only join the Xia Kingdom, only this one choice represents "life", and we can live a better life by joining the Xia Kingdom. ”

After several fierce discussions, the high-level leaders of the Liu tribe still did not unify their thoughts, but some people in the "moving" camp changed their minds and joined the "join the Xia Kingdom" camp, and the number of people in the two camps gradually developed from one to two to two, and is developing towards one to one.

Regarding the ultimatum of the Xia Kingdom, the high-level leaders of the Liu tribe did not keep it a secret, and soon the matter was known to all the tribesmen of the Liu tribe, and the ordinary people of the Liu tribe also fell into the discussion, and they would discuss a few words in their free time during work.

Very different from the high-ranking people of the Liu tribe, more than two-thirds of the ordinary people in the Liu tribe chose the option of "joining the Xia Kingdom", their idea was very simple, joining the Xia Kingdom would make life better, and moving would make life more difficult.

The fate of the Liu tribe is in the hands of the high-level of the Liu tribe, and no ordinary clansman can decide the fate of the Liu tribe if they have any ideas, but some high-level people of the Liu tribe are influenced by ordinary people, and their thoughts have changed, and they have changed from the "moving" camp to the "joining the Xia Kingdom" camp.

It is the first time, the number of people in the high-level of the Willow tribe who "join the Xia Kingdom" camp exceeds the number of people in the "moving" camp, although there is only one more person, but you can see the great changes in the Willow tribe, "joining the Xia Kingdom" has become the best choice for the Willow tribe, and then it only depends on when most of the high-level people of the "moving" camp can be pulled into the "join the Xia Kingdom" camp.

Among all the tribes that issued an ultimatum to the Xia Kingdom, the Liu tribe was the fastest tribe to "join the Xia Kingdom", and most of the other tribes had fierce quarrels, with the "moving" camp in some tribes having an absolute advantage, and the tribes sending a team to choose the address of their new home early, and some tribes slowly falling to the "joining the Xia Kingdom" camp like the Liu tribe, but at a slower pace.

If the Xia Kingdom knew about these changes, it would be very happy, there were "stubborn" tribes who could change their attitudes and join the Xia Kingdom, which was definitely a huge gain, and they had only given an ultimatum to the tribes with a trial attitude, and the officials of the Ministry of Commerce had not reported much to the tribes.

The spring ploughing has just ended, and the women with big bellies in the palace are about to give birth, but Su Yan had to take two days to leave the palace and leave Zhongjing City, and go to Chicheng, the Chicheng smelting area is about to smelt iron ore, iron smelting is a very important thing for the future of the Xia Kingdom, and the first time to make iron, Su Yan needs to be in charge personally.

Take a boat to Chicheng, and then take a carriage to the Chicheng smelting area, the matter of smelting iron ore has been prepared, and you can start work just waiting for Su Yan to arrive.

"Let's go!"

Put coal and iron ore into the iron-making furnace, ignite the coal, and blow air into the iron-making furnace with a hydraulic bellows......

Seeing the molten iron gushing out of the outlet of the iron-making furnace, Su Yan understood that the iron-making was successful, and for Xia Guo, whose copper-smelting process had reached a certain level, iron-making was not such a difficult thing.

"You have done a very good job, you have smelted iron the first time, you have to continue to work hard to improve the ironmaking process, there is much more iron ore in the land than copper ore, and iron will definitely replace copper in the future."

Hearing Wang's words, the people in the smelting area became excited one by one, the Chicheng Smelting Area and the Yuancheng Smelting Area are both smelting ores, and now the importance of the Yuancheng Smelting Area is higher than that of the Chicheng Smelting Area, and the people in the Chicheng Smelting Area dream of making the importance of the Chicheng Smelting Area higher than the Yuancheng Smelting Area, and Wang's words seem to have made them see the day when the importance of the Chicheng Smelting Area is higher than that of the Yuancheng Smelting Area in the future.

Su Yan did not hesitate to praise the people who worked hard in the Chicheng smelting area with words of appreciation, and at the same time, Su Yan also noticed one thing, the black smoke coming out of the iron-making furnace.

Compared with ironmaking, copper ore is smelted using charcoal as fuel, and the raw material of charcoal is firewood, and the gas produced by charcoal combustion is mainly carbon dioxide.

Coal is different, coal contains more elements, especially sulfur, sulfur dioxide produced after coal combustion will seriously pollute the environment, environmental pollution, this is indeed a very serious problem.

The development of industry will inevitably lead to the pollution of the environment, if you want to reduce the pollution caused by industrial development, it is impossible in a short time, Su Yan can only do to keep the pollution away from the area where the Xia people live as much as possible, and reduce the pollution of water sources and fields as much as possible.
