For a long time, Yun Zihuang took the letter that Feng Qingxiao wrote to her, but she didn't open it. Her missing never stopped. She never had to think of it, because she was missing all the time. Fingers, over and over again stroking the letter, it seems that the letter, but also with her peace of mind, the cold smell of pine forest in the snow. This is the third letter he wrote to her, but she hasn't written a reply so far.

The first two letters, which she did not open, remained sealed.

Because she knew that once she opened the letter and saw his words, missing words and caring words, it would be difficult to control her emotions. Miss, as early as the spring grass, crazy growth, open the letter, she may be desperate to go back. However, she can't go back now. Whether it's the biggest war crisis in a thousand years or the unsolved problem, she can't go back.

To keep yourself busy is to be distracted. During the operation, when participating in military aircraft analysis, you can not think about him for the time being.

He knows how much he misses her and looks forward to seeing her reply, but writing back will only increase the pain of his missing and make him more sorry.

Put the letter in her hand into the empty compartment, and she closed her eyes.

These naive too tired, heart and body of double extreme fatigue, perhaps Ouyang Baofeng said right, she should have a good rest. It doesn't take a few days, even if only one day, to have enough to eat, drink, take a bath, have a good sleep, and let yourself return to a good state, so that you can do more things. This time, she sneaked out of Kyoto and went to northern Xinjiang. She didn't bring her servant girl. Ouyang Baofeng sent her servant girl to wait on her. She only left two of them in Zhanshen city without her.

In the intelligent brain, we silently analyze and deduce the possible changes in the future development of the war situation.

Now is the most difficult time, the war continues every day, and the enemy's attack is even more crazy and desperate. She understood that the enemy wanted to conquer Northern Xinjiang while there was still some morale and strength. As long as they could capture some important towns in Northern Xinjiang, they would have a foothold and their morale could be stabilized. This time, Ouyang Baofeng still plans to shrink his defense line. The former isolation area and some places have become pocket arrays for actual combat training.

Up to now, the wind seeking army has not put in many troops, mainly using local garrisons against the enemy.

As long as we can survive this most difficult period, with more and more sick people among the enemy troops and lack of food, grass and supplies, the balance of victory will gradually tilt towards Northern Xinjiang.

"How much longer?"

She sighed that it was not easy to judge the time. In fact, through the efforts of this period, the war situation has been reversed.

The next morning, the staff of the staff office found their empress appeared again, with a low-key smile and Tiewei, bringing them a delicious breakfast. Later, the empress's staff officer looked at the military map in a daze and said nothing. They know that the empress is thinking about many problems, and many of the decisions made by the Grand Marshal have adopted the empress's suggestions and clever plans.

"Here comes Shuai Ye!"

Someone raised his voice and said, the staff members all stood up in a hurry and bowed to Ouyang Baofeng: "see you handsome."

Yun Zihuang stood among the people in a low-key manner, and stood up with them to salute the Grand Marshal of North Xinjiang.

"No, sit down."

Ouyang Baofeng walked through the crowd. After bowing to Yun Zihuang, he didn't say anything. He went to sit down, and the crowd sat down.

This is where countless top secret strategies and military aircraft decisions in Northern Xinjiang come from.

The staff are pondering. Shuai Ye issued many military orders yesterday, and they have been thinking about the profound connotation of these orders. At the same time, they all looked at the queen with eager eyes. A few days ago, Tiewei, led by the empress, used a weapon called thunderbolt bullet to turn defeat into victory. It not only broke through the encirclement of the powerful soldiers of the rising Empire, but also helped the new army in the last line of defense to defend the defense line. It also took the opportunity to attack the enemy and make the whole army of the enemy exhausted.

They have begged the Grand Marshal many times to make it clear to the empress that it would be better to have a large number of the same weapons in each army.

Ouyang Baofeng said in a deep voice: "staff cloud has begun to manufacture fire mines. However, the time for materials is limited. It takes time for professors to manufacture them, and it is not possible to manufacture them in large quantities. Therefore, these fire mines must be used on the blade at the most appropriate time and where they are most needed. Cloud staff, explain the use, lethality and scope of fire mines. "

Yun Zihuang stood up: "according to the order, the first kind of mine I developed is mine. It is buried underground. The killing range of each mine is three to five feet, which can make the enemy in this range die, seriously or slightly injured. The second is bombs, which can be thrown by hand and shot with bows and arrows. The killing range is one to three feet. The power is weaker than that of mines, but it is more convenient. These two kinds of fire mines are poisonous. Even if the enemy is slightly injured and can't get effective medicine, he will soon be weak and die... "

Yesterday, Yun Zihuang talked with Ouyang Baofeng about firearms. The number of such thunderbolt bombs is limited, and they are not enough to be equipped in too many troops. The materials needed to make thunderbolt bombs are not complicated, but they are not everywhere, and she does not want to mass produce them. The thunderbolt bombs provided to the iron guards are the great God of the empty capsule. They have been made day and night for several months.This time back to Ares, we also want to make simpler firearms for use in the battlefield.

We have started the manufacturing test, but it will take some time to manufacture in batches. Simple and dangerous mines, as well as bombs that can be used for throwing and shooting with bows and arrows. All these things need to be manufactured and consumed at the same time. After all, the space in the empty storage tank is not unlimited. Moreover, these things are also very dangerous. They can not be manufactured and put too much in the empty storage tank. It is inevitable that there will be problems in transportation.

So these things can only be made in Northern Xinjiang, and she has been hesitating whether to make these things.

In this era, there is nothing related to firearms.

Once these appeared in this era, she didn't know what direction the history would take and what changes would take. If the war situation in Northern Xinjiang had not been so urgent and dangerous, she would not even have equipped Tiewei with thunderbolt bombs.

The reason why she made up her mind to make these firearms was that her father Wang Yunfei was injured and nearly died in a battle with the enemy. Because of this, she ordered Tiewei to send some thunderbolt bombs to yunfeiding.

She sighed secretly, across hundreds of years, maybe even thousands of years ahead of the era of firearms, so she was brought here!
