The rainy season should begin at the end of June in the north, and this summer there was no heavy rain, which is considered dry.

Originally, Chen Mu thought that there would be no more heavy rain this year until winter, but now looking at this celestial phenomenon, I am afraid that it will rain soon.

It's raining, since he has the bird gun team in his hands, Chen Mu has hated rain, and later there are boats and cannons, even more so.

Because the rain means that the combat power of his subordinates has dropped sharply.

Without artillery and without a bird's gun, his ability to command combat was greatly weakened, because his tactics relied on firearms, otherwise even a single general could defeat him in cold weapon combat.

Fortunately, what awaited him was not an encounter, but a defense, and it was the defense of the riverbank bridgehead that he was more familiar with, and it was even more powerful than the conditions of the Battle of Xinjiang.

It is very long along the Juma River, but it is also very wide, although there are a few places where the water depth is less than half a person, but most of them form a valley between the mountain walls on both sides, and there is no road for the Mongol cavalry to pass, and there are only two real gaps.

One is to leave a back road for the friendly troops in front of the more than ten paces wide tethered horse bridge, the other is in the northwest of the tethered horse bridge fourteen miles, and once it rains, the river water from the source of the mountain will swell, making it more difficult for the enemy troops there to cross the river, so the garrison mission is not difficult for the 4,000 banner army.

What's more, between the two main roads, there are more than 4,000 flag troops fortified and garrisoned, and it only takes half an hour from the sentinel to the reinforcement of soldiers and horses.

The artillery position is a big operation, and twenty-four artillery pieces of different weights will be placed a hundred steps directly behind the gunner's position, and Chen Mu asked for a solid earth square with a height of one zhang, a width of forty-four steps, and a length of forty steps, and a gentle slope of twenty steps behind it, and a huge canopy should be set up and down the slope.

On the slope, the artillery and cantonment are put to cover the rain, and the bottom of the slope is to cover the pack horses, so that once the situation is not good, the artillery can first move quickly with the artillery - but to what extent it can maneuver depends on God's will, once the road is muddy, the artillery will not run fast.

Fortunately, not far from the position is the Sanhe Tuguan Road, as long as you can get there, even if it rains, the gun truck can let go.

In Chen Mu's design drawing, the trench is a hundred steps in front of the artillery position, and it is an eighty-step arc-shaped trench five steps wide and four feet deep, on which the slope is placed from the back to the front with wooden planks and large shields, and the planks are supported by big sticks every two steps in front of the trench, and the board is covered with a tent cloth soaked in tung oil to waterproof.

In front of the trenches, a row of large shields was placed horizontally, and the rainwater was also directed to the outside to provide part of the protection and erection of the flag army.

Chen Mu named it Chen's rainproof trench, and drew two copies of the composition, one was handed to the head of the subordinate miners for Hu Daxiong to supervise their excavation of the fortifications, and the other was sandwiched in a notebook for later tidying.

The miners are very useful, he has long wanted to establish a local army under his banner, but he was interrupted because Qi Jiguang transferred him to the north, but he didn't expect Xu Jue to recruit a group of miners for him, not to mention other people, the miner Chen Mu must recruit his own hands.

That is, there are many banner troops in hand, otherwise Chen Mu would not be able to build such a big project in a short time, but this is the benefit of local warfare, and the people within a radius of more than ten miles of the handbook are all helping to cut down and transport, and of course, there are also people who fled from the war in Baoding, and they were also intercepted to work in Fangshan.

How does cement burn?

Limestone and clay grinding flour, burned and then mixed with iron-smelting slag?

But Chen Mu didn't know the ratio, so he could only try it exhaustively, and after writing it down in his notebook, he sent a letter to Nanyangwei.

If this thing can be made, it will be equipped with masonry and steel bars...... Can frying steel make steel bars?

Don't care if you can or not, try it first.

Even if it can be made, this thing is not very useful in the north, and the northern captives can't even shoot down the wooden wall, so they still have to use it in the south.

Later, he loaded more than a dozen ships of concrete and steel sticks, drove the ship to Malacca and Luzon to build turrets, side by side with the Portuguese and Spanish forts, and the big deal was to shoot at each other's artillery to see whose strength was strong!

What the? Is this aggression?

No, no, no, if that happens, it must be a just war, for the sake of Manchuka and Luzon without changing the name of Malacca and the Philippines, fighting for the honor of the tributary state is General Chen's lifelong pursuit.

But now, he has to win this battle first, even if there are no difficulties to create difficulties.

He needs a beautiful victory to establish his prestige in the three guards, and he also needs a gorgeous enough battle to be promoted, and now Chen Mu seems that the northern transfer is not a bad thing at all, and he has found another breakthrough for him - a direct arrival in the DPRK and China to make friends with the country, and obtain the power to open the sea in Nanyang.

The matter of maritime politics is too big and will hurt the interests of too many people, and this is not something he can do alone, and he needs strong support.

Fortunately, there are at least two leaders in the current cabinet who are bent on making the country rich and the army their own responsibility.

To tell the truth, Chen Mu now understands very well the mentality of constantly building the Great Wall and pulling out a long line of defense.

There is no Internet and no telephone, and war reports and police reports can still be transmitted by beacon fire in short-distance coastal defense like in Guangdong, but in the northern part of Xinjiang, it completely relies on two or four legs, which is too slow.

Our messengers galloped on horseback, and the enemy troops galloped on horseback, and the governor received a report of the battle and sent his troops, and the soldiers and horses set out from this side, and the enemy horses had already run to the other side, and there was another great plunder.

If you want to stop a ranger, you need to use several times the strength of troops in all directions to besiege it, but the distance of the soldiers and horses is different, the place and time of the troops are different, how easy is it to encircle it? I am afraid that it is more likely that before the encirclement has been formed, it will be divided and attacked by the enemy's faster maneuver and the mobilization of superior forces.

Over time, the young soldiers did not dare to fight, and the large soldiers did not have time to fight, so it became such a weak situation - the movement of the army was judged entirely by the battle reports of the fallen cities, and it had not yet knocked on the pass, and the pass was already in full battle.

If it does not want to come to the capital, it is only to bring disaster to Shanxi, then the Ming army is helpless.

In fact, most discerning people know that peace is the only way out, and they have been arguing since April, and they are still arguing, and the fundamental reason for arguing is nothing more than whether to promote peace by war or by money.

Either way, everyone is waiting for the outcome of the war, but some need a victory.

And Chen Mu was busy praying to the heavens outside of the military, and he prayed that the Tumut tribe would rush to the Juma River, because the man who had come all the way from the south stubbornly believed that the great victory that the world had been waiting for would be in his hands.

On the 7th of September, it rained and the Juma River swelled, and the war-torn victims on the other side of the river came one after another, bringing the news that the Beiyu had crossed Jingcheng and entered Zhending. At the same time, Nanyangwei's second artillery delivery also entered the Beijing Division, sending Bai Yuanjie's information about Nanyangwei's affairs, and it also came with a piece of leather-like things.

Chen Mu's short saber pierced the soft thing of unknown structure and nailed it to the case, looking excited.

"Come on, come on, let me bang you!"
