Zhang Li, Chen Zhengcao, and Kang Xingan thought about many possibilities, and even finally found Gao Yuanliang, and the four of them pondered together, but they still couldn't figure out why Hong Chengchou acted like this.

In the end, in desperation, Zhang Zhang had no choice but to put the matter aside and told Chen Zhengcao to send more ships out to investigate to see if he could find the traces of the Tartar sailors.

After Chen Zhengcao received the order to leave, Zhang Zhang couldn't help but feel a little depressed: there is no radar or GPS positioning in these days, and it is really a small probability to discover the enemy's movements in the vast sea, and it is not much different from resigning himself to fate......

What kind of medicine is sold in Hong Chengchou's gourd?

Back in the middle military tent of the barracks, tension held everyone back, and began to ponder again. The first sentence of "The Art of War" is "Soldiers, the major affairs of the country, the place of death and life, and the way of survival, must not be ignored." ”

As the so-called fierce battle is dangerous, don't look at the Tuanshan Army before, but this time the Korean War is to gather the main force of the Tuanshan Army, if there is anything wrong, the consequences are unimaginable.

Zhang Zhang already knew through the eyes of the intelligence department of the Tuanshan Army in Shenyang that Hong Chengchou had brought in a group of Western mercenaries, numbering about two or three thousand, and it was not clear what the combat strength of these people was.

Zhang Zhang stood up, stretched his waist, and ordered the guards outside the tent to make a pot of tea and send it into the tent. After a while, steaming tea was brought in, and Zhang Lizhong sat on the Taishi chair again, thinking about the next battle strategy while drinking tea.

The tension of Kong Youde's sailor is put aside for the time being, and it is only right that the battle in front of him is fought well. According to Zhang Li's plan, the fire reconnaissance in the past few days has found out all the positions of the Qing army's artillery. All that's left is to find an opportunity to give them a pot.

After settling the artillery positions of the Qing army on Songak Mountain and Centipede Mountain, the Battle of Kaesong entered the rhythm of the Tuanshan Army. In the dignified frontal battle, what are the chances of the Qing army Mu.

……

After the fall of the Ming Dynasty. Zhang Lili ignored public opinion, did not use the new era name, nor did he continue to use the Chongzhen year, but used the Western era.

This is really a big deal, and it has attracted everyone's attention. At least for now, it seems that Lord Zhang has no intention of immediately founding the country and changing the yuan. And the tension uses the Western French Era, which also makes everyone fall through the glasses.

The "Great Unification Calendar" implemented in the Ming Dynasty is the successor to the "Time Calendar" of the Yuan Dynasty, and the days are long. It is seriously inaccurate. Until the solar eclipse in May of the second year of Chongzhen, Xu Guangqi calculated the most accurately with Western law, and the Ministry of Rites asked to open a calendar bureau. With Xu Guangqi supervising the revision of the calendar, the calendar change work was finally on the right track, but later the Manchu Qing Dynasty invaded the Central Plains, and the calendar change work was not actually completed in the Ming Dynasty.

Xu Guangqi's achievements in the astronomical calendar are mainly concentrated in the compilation of the Chongzhen Almanac and the various sparse works written for the reform of the calendar. In the almanac, he introduced the concept of a circular earth and gave a clear introduction to the concept of the latitude and longitude of the earth. He introduced the concept of magnitude to the Chinese astronomical community. According to the Tycho Catalog and the Chinese Traditional Star Catalog, the first all-celestial star map was provided, which became the basis of the Qing Dynasty Star Catalog, in terms of calculation methods. Xu Guangqi introduced the accurate formulas of spherical and plane trigonometry, and first made corrections for parallax, air and time difference.

Xu Guangqi also gave a detailed account of the Western era in the Chongzhen Almanac, but it was limited to the political environment at the time. That's absolutely impossible to use.

Now that the Ming Dynasty has died, it is time to implement the Western Era. And the tension is considered at a deeper level. It was by taking advantage of this trend of changing the Western Era that the development of astronomy and physics was actively promoted in Liaodong and Shandong.

The use of the A.D. era has been in short a month. Xu Guangqi's "Chongzhen Almanac" was almost sold out. By the way, he translated and compiled books such as "Geometric Originals", "The Complete Book of Agricultural Administration", and "Explanation of Examination Work" and other books......

In the ninth year of Chongzhen's reign -- uh, no, it should be called June 16, 1636, after the Tuanshan army ended a day of "routine shelling", the Tuanshan army camp under Songyue Mountain returned to calm.

As usual, the scouts in charge of the guard were scattered in all directions of the camp, and the number of scouts in front of Mt. Matsudake was the largest. Bursts of cooking smoke wafted from the camp's rooms, and the time to bury the pot to cook was the same as usual.

However, in the heavily guarded camp, 10,000 selected soldiers of the Tuanshan Army had completed the assembly and quietly waited for the commander's order.

The 10,000 men were divided into three teams, and the soldiers did not stand but sat cross-legged, for they needed to conserve as much strength as possible in order to accomplish their task.

The cooks brought up truckloads of steaming white flour steamed buns and potatoes and began to distribute food to the soldiers. Each soldier had three large steamed buns, plus four large boiled potatoes.

This is the configuration of two meals - three large steamed buns are eaten now, and the boiled potatoes that are more convenient to carry are precisely for the evening battle.

That's right, tonight, these 10,000 soldiers of the Tuanshan Army are going to launch a night attack on the Tartar artillery fortress of Songyue Mountain!

The soldiers were between the ages of sixteen and twenty-six, and were at their best for physical strength. Years of natural and man-made disasters have made it difficult for people to live longer than 30 years old on average, which really makes Zhang Zhang sigh.

Zhang Zhang looked at these "loveliest people" and couldn't help but feel a little emotional. I wonder how many of these 10,000 people will still be alive when the sun rises tomorrow......

Soon Zhang Li reined in his thoughts, and said to Gao Yuanliang, the main general who was out of battle tonight beside him: "Yuanliang, the Tartars are not completely defenseless at night, and they have also arranged a large number of scouts - what do you think of tonight's battle?" ”

Gao Yuanliang straightened his throat and said, "My lord, we still have a good chance of winning if we choose a night attack. Although the Tartars also have scouts, this time we chose to attack from both sides......"

Zhang Li bowed his head slightly, and said to Gao Yuanliang: "Yuanliang, I remember that the last time our regimental mountain army attacked at night was when Chongzhen was five years ago, and it has been four years since I counted on my fingers. This battle is well fought, and the artillery positions of the Tartars must be pulled out! ”

Gao Yuanliang promised loudly: "The last general will take the order!" ”

The sky gradually darkened, and Gao Yuanliang also took 10,000 people out of the camp, divided into two roads, east and west, and quietly marched towards Songyue Mountain. The soldiers who came out of the camp were silent one by one, only silently following the steps of the previous one, each with a serious expression, and the whole team did not have the slightest noise.

Zhang Zhang waited in the tent of the Chinese army for good news from the front, this night, destined to be sleepless...... (To be continued.) )
