The construction period of building the fortress was too slow. Han Zhenhan took out the method to cement, burn lime, paste leather with wooden boxes, pour cement, and then bake the surroundings with fire to speed up the drying. Then he continued to increase the height of the cement on the original outer wooden fences, so that the entire fortress became a castle with wooden beam concrete structure.

Especially the three fortresses that are prioritized, with gray walls, high city and deep pools. At first glance, it looks magnificent and magnificent, making people feel unattainable.

The location at the middle connection is also underway for a lot of construction, and three-story wooden railings have been built. Some of the faster construction sites have now started to pile up those cement blocks in the middle and outside of the wooden railings.

The application of cement is extremely useful for Han Zhenhan who guards the Jinsha River. Jinsha River, let alone how much gold there is in the Jinsha River, but there is definitely more sand than gold.

Other lords or local tyrants were rushing gold in the Jinsha River. Han Zhenhan was better. While he was driving the river with his people, he kept digging sand in the river. The dug out sand went upstream directly through the river, crossing the river, and then went ashore to the Dongchuan Fortress with various trolleys, as well as mules, horses and ox carts to the bottom of Dongchuan City.

The firing of lime is not difficult. The fireworks workshop in Luzhou provided Han Zhenhan with a lot of gunpowder. Although it was primitive black gunpowder, it was much faster than people who opened mountains to get stones.

And choose a blowing point and a single burst to remove a large number of large stones. Then build a kiln to burn stones to make lime. Regarding lime making cement, Han Zhenhan accidentally heard the warriors bragging when he was leading people to dig rivers.

A new soldier, of course, was already a thousand households at this time. He sat on the shore with a few old brothers to make a fire to keep warm. He talked about the past of the world, saying that he had worked by the waterside, but he had done it for the Germans before. He said that those big noses were really amazing. How could they think of burning stones into powder and mixing them with sand to create the strong, durable, and unscathable cement.

Han Zhenhan, who was passing by, didn't take the word cement seriously when he heard the word "cement", but when he returned to the camp, the more he thought about it, the more wrong it was. The role of cement, cement, and cement was not a little helpful for improving construction technology.

In the middle of the night, Han Zhenhan jumped up from his bed, found Sun Hu and asked questions. He found the guards around him and asked questions. The questions he asked were very simple.

"Who can burn lime, who can make cement..."

But of course, Han Zhenhan didn't know the answer. Everyone was tired for a day, but it was still midnight. People were crazy about asking some stupid things. They thought that Han Zhenhan would go back to sleep honestly without getting the answer, but found that they could never see through their leader.

All the 1000-year-old centurions gathered, and all the soldiers from the original New Regiment gathered, but the question asked was, who would be cooking fire by the river after 3 pm today.

Everyone was confused. Everyone didn't know how to answer the question of Han Zhenhan. They didn't know whether the person who went to the river to cook the fire made a mistake or made some contributions. The leader of the regiment needed to jump out in the middle of the night and called everyone to ask this question.

Sun Hu was also unable to figure it out. He was not looking for lime just now, but now it is a fire. Lime is a fireworks, and fireworks are a fireworks. This is not a job.

Of course, Han Zhenhan knew it would be more convenient to ask directly, but you should know that there are too many people and that he has done enough to make everyone pay attention to it. If you ask cement concrete in a name, wouldn’t this question be to tell others that his city fortress in the future were made of something called cement?

So after Han Zhenhan's screening, there were as many as seven people who said that he could recognize limestone, and one of them was actually a person from this time and space that the brothers called in Yuncheng.

However, Han Zhenhan is definitely not looking for him, but Han Zhenhan still whispered one by one and whispered to the seven people. In the end, everyone was disbanded and was fine.

The next day, a brotherhood soldier named Ge Xiao was brought to Han Zhenhan. Seeing this man coming, Han Zhenhan's eyes were as dazzling as a wolf when he saw a beautiful woman.

Then he was still working as his own chief executive in his position, but in fact, the lime factory was completed quickly in secret. Then he began to put the lime into use efficiently.

With cement concrete, the current Dongchuan Fortress was found. Otherwise, the Dongchuan Fortress would not have much manpower and material resources to build the scale into its current appearance. At the same time, it occupied the northwest and southwest of Dongchuan County and the east direction. After reasonable choices, the three locations have begun to be built with interconnected traffic roads in various places.

Among them, the Guban tribe and the Dongchuan Fortress can transport a large amount of things by water and land. These three important towns can be said to have defended the defense of the entire Dongchuan County. The most important thing here is the Dongchuan Fortress, whether it was a battle with a huge casualties and injuries here, or the Mongolian general Urya Cha who died in the fall of this place.

In short, since the news of Han Zhenhan launching the banner of the Dali Restoration Army and killing Wulianghecha, countless young refugees who come to Dongchuan Fortress every day have come to surrender.

However, Han Zhenhan still did not leave any one. After all, after ascending the throne and building the book, all of them were flown down in Luzhou by boat. In Luzhou, there was Staff Wang in charge. Those Dali people were really obeyed by Staff Wang. The speed of the support field was far from comparable to the training instructors before.

The Bai soldiers and Bai people who were taken back one after another began to live near the Miao villages. Moreover, the earliest group of Bai people who moved to the past also began to march towards Dongchuan County.

But in comparison, Dongchuan County exported more people than those who came in. In the past month, the entire Dongchuan County, including the Miao people, had a population of more than 50,000 to Luzhou.

This is why Han Zhenhan needed a large number of prisoners of war work, otherwise the population that was released back to Luzhou would be larger.

Knowing that at this time, Liu Zhenhan from Luzhou sent a letter to Han Zhenhan, because no matter how thick the paper was, it would definitely not be able to contain the fire. Liu Zhen didn't know where he was in the omission, and someone actually conveyed the news that Liu Zhen had sent troops into Dali to Lu Wende of Chongqing Prefecture.
