It seemed that he had arranged everything unilaterally. Guo Shitong felt a little relieved. He suddenly thought of Xiao Zhiqing and couldn't help but think about it: "Then Marquis Wu'an is here?"

"Of course it's impossible for him to show up. The guards have all seen him. Do you want to see Xiao Zhiqing?" Qin Feng said: "She is in a bad situation now. She joined the army as a woman and she managed to convince a bunch of big men to convince her that she was

Not even a tigress is too big."

Thinking of Xiao Zhiqing waving his whip at him, Guo Shitong licked his lips: "Even if it is a tigress, she is still my favorite tiger. Women are so gentle and carefree all day long. It makes me tired to look at her. She is so good and powerful."

Qin Feng glanced at this shameless thing and sneered: "You are not the only one who finds her exciting."

According to Xiao Lingyao, there have been quite a few people asking to marry Xiao Zhiqing from the Xiao family recently, but Xiao Zhiqing has ignored them all and is only thinking about making achievements. She even said that she would be Da Kun's first female general!

Guo Shitong became anxious when he heard this. Since Xiao Zhiqing left, he felt empty in his heart. Now he would like to thank Emperor Yuan for giving him this opportunity, which not only left a way out for the Guo family, but also had the opportunity to meet Xiao Zhiqing.

Li Shijian and the others had met Marquis Wu'an, but they certainly had not met Xiao Zhiqing. Xiao Zhiqing never attended palace banquets and did not take it seriously.

So she has never appeared in front of His Majesty. Isn't this just her opportunity?

Seeing that he was starting to have unrealistic dreams, Qin Feng interrupted him angrily: "The love between children is long and forgotten. Do you remember what I told you before? You must understand why you are here.

I joined you to fulfill the emperor's wish."

"I know, it's just a new medicine. I'll definitely bring it with me when I return," Guo Shitong said, brushing away his previous gloomy mood, "I'll just follow your arrangements when I get up."

Qin Feng smiled and took out a lot of fresh gadgets to share with him. Outside, Cao Jing, who was guarding, thought of the two of them having fun like this when they were in the princess mansion. Although Guo Shitong was noisy, he could indeed

Makes people feel relaxed.

It would be a pity if such General Guo Shen died.

The night passed quickly, and at dawn, Qin Feng took the initiative to let the ship continue to move forward. The watchtower, which was originally just a bunch of shadows, became more and more obvious. When he saw the fortifications on the sea, Guo Shitong, who was standing on the deck, cursed.

They had also seen the maritime fortifications of East Vietnam when they boarded the ship in the southeast, but what they saw now was very different. For example, these tall watchtowers should have been designed with bow and arrow stands, but what they saw was the same as those in East Vietnam.

The more completely different the reservation window is.

Qin Feng would not tell them that those were forts, which were reserved positions for firing gunpowder shells, in order to welcome them, but he moved the cannons aside early to prevent them from seeing them, and all he could see were the bow and arrow positions.

They had never seen the fort, but they thought it was an archery platform, and the bunker was a product of modern warfare. It was only widely used in major battlefields during World War II. After Qin Feng got the concrete out, the first thing he had to do was build a bunker!

The ancients had infinite wisdom. They knew how to dig trenches, fill them with burned earth, and support mud walls with wooden bones. This technology was actually very similar to the concrete technology of later generations. Qin Feng figured out the principle without much effort.

Use fire-burned soil as the filling material for the foundation trench and the wall. Use wooden sticks in the foundation trench as support columns for the wall. Then fill in the red-burned soil blocks and apply thicker coating on both sides of the wall.

Mud may also be reinforced with reed poles.

This kind of construction technology is very popular and has an extremely early origin. It can be traced back to five thousand years ago. What was the concept five thousand years ago?

While sighing, Qin Feng also invented cementitious materials. Based on the ancients, he was able to build a fully functional bunker, and the bunker was a defensive military facility. Junqu Pavilion

The bunkers were not built on the sea, but were distributed on the shore. Guo Shitong and the others thought they were ordinary earth bunkers. Naturally, Qin Feng would not tell them that these bunkers could best defend against enemy attacks during the war.

There are generally three types of bunkers. One is a bunker in the traditional sense, which is low and hidden. The second type is similar to a bow and arrow tower, which is located higher and can attack opponents from high places. The last type is located in a city fortress and covers an area of ​​​​The widest, can be attacked and defended.

Except for the last one, which has not been paved since the longest construction period, the first two were built very quickly during this period. Qin Feng knew at a glance that he must be rushing to work during the time he left, and the progress was good.

However, only the ones on the ground were well built. When Qin Feng designed these bunkers, he designed them into two floors. Although they were not as good as the four or five floors during World War II, they were already an epoch-making invention at that time.

The exposed parts of the ground are muskets and artillery fortifications to defend against attacks, while the underground is more sophisticated.

The layer built underground must store ammunition, food, daily necessities, and serve as a command post after the war breaks out. In addition, it must also store medicines and even be built directly as a rescue center to treat injured soldiers on the battlefield. Bandage the injury.

Both the above ground and the underground are important. It had just been built when Qin Feng left, and the above ground was just completed, but now is not the time to look at the underground.

He had estimated earlier that if only one underground floor was built, a small bunker could accommodate forty to fifty people, and the supplies inside would be enough for them to live for more than a month. If there was a war, it would be extremely difficult for the enemy to conquer the bunker. Disaster.

While the opponent is still using cold weapons, they have already entered the gunpowder stage. This gap is extremely difficult to overcome.

Didn't Guo Shitong ask him where his confidence lies? These are his confidence!

Qin Feng smiled slightly. Fortunately, although Guo Shitong was surprised to see these things, he did not ask questions and suppressed his curiosity. In front, there seemed to be a group of soldiers waiting on the shore, and the leader was a younger sailor. Division general.

It wasn't Han Ming. Qin Feng couldn't help but smile. In fact, it didn't matter if Han Ming appeared. When Han Ming was fighting on the water many years ago, these guards were still playing in the mud. It was impossible to see him. However, how could they bother Han Ming? Will you welcome me in person tomorrow?

When the ship docked, Qin Feng took the lead to jump off the ship and came to the general: "I have seen the military master. I think the military master also knows that the East Vietnam Kingdom sent an envoy with a customs clearance document."

"Send it up." Although the young general was not old, he was full of energy. After reading the customs clearance document, he immediately let him go: "Cao Shilang of the Ministry of Rites is already waiting. Please go forward."
