Bai Yuanjie sent a letter from the Nanyang Guard. Although Chen Mu was not in Nanyang, the personnel left behind could ensure that the Nanyang Guard would continue as Chen Mu's arrangements before leaving.

The Hexingsheng fleet had gone several times, and the Weigang was still under construction. Qingyuanwei failed to plant Eucommia ulmoides on a large scale, but they purchased a large amount of Eucommia ulmoides leaves from Huguang to make glue, making this piece of thing that seemed useless.

In short, everything is fine, but the son is lost.

Li Dan took the Hexingsheng fleet to make a fortune in Malacca and returned to the Nanyang Guard to replenish the goods. Then he went to Luzon and sent someone to send a message back. He wanted to live in Luzon for a year and a half. He didn't bring much silver or a few ships, but only a group of men and went to the ocean.

He said he had found something yellow, but he couldn't grow it. He wanted to learn from Luzon Fanyi, how should he grow it?

The Nanyang Guard has really grown. In the past six months since he left, all the roads paved in the past have entered a state of prosperity. Whether it is the market, fleet, shipyard or military industry, the shark boats produced by the Xiangshan Shipyard are moving towards the 400-foot large ship, and the 200-foot small boats have really become what Chen Mu expected, and become the fishing boats of the Nanyang Guards.

This will be their first step in dominating Nanyang.

Compared with the Nanyang Guard, the situation in General Chen's northern defense zone is getting worse and worse.

The Tumot tribe is really sure to enter.

The first to attack was the Right Guard of Shenwu. The local defenders were unwilling to bribe the Northern Barbarians, nor were willing to defend the city. They won a small victory with the enemy cavalry outside the city. Then they made a rash move into the encirclement of the enemy cavalry. They were unable to advance in an inch or return. After the defeat, they were killed and looted, and half of the troops fled in scattered.

Then the partial divisions of the Northern Lu were invading Baoding and conquering the Qingdu area of ​​Tang County. At the same time, the army of the Northern Lu also entered Baoding Prefecture from Lingqiu, Shanxi, and the troops were knocked on Zijing Pass. The pass was defending the pass, but they were attacked by the enemy from both sides. The two enemy troops combined more than 10,000 troops, and the soldiers guarding the pass were alone and could not support them. On just ten days of guarding the pass, the generals of Zijing Pass saw no troops coming to support him, and led their troops to abandon the pass and retreat to Yizhou and Laishui, and entered the southern capital to defend.

The enemy cavalry's outpost is less than a hundred miles away from the water of the horse.

It was not until this time that Chen Mu found out who his enemy was.

It's not Altan, Altan's main force is still in Datong. Because there are internal problems, it did not continue to go south. Chen Mu needs to face a tribe under Altan's control. Altan's brother Ji Nengsou led troops and more than 10,000 infantry and cavalry. His tactics were to imitate the story of the Mongolian army breaking through Zijing Pass and fighting all the way to Beijing Xizhimen.

For Chen Mu, the situation is very good.

"It's so weird for the barbarians. My uncle is fighting with us, and my grandson comes to join us." Deng Zilong took the letter and said to Chen Mu: "I took Han Naji because Altan married his fiancée and took more than a dozen people to Datong to ask for surrender. The governor allowed it. The court was very happy about this, so Altan gathered 100,000 troops to the border to seek Han Naji."

Chen Mu received the letter, and after reading it for a while, he couldn't understand the relationship between the characters in it. He regarded Han Naji as Altan's grandson, his fiancée as Altan's niece. In short, in this mess, the Ming Dynasty added another important bargaining chip to the purpose of peace talks with Altan.

"Don't worry about the affairs of the court for now." Chen Mu took the letter back to the desk, walked out of the tent and looked up in the mirror. His vision was hazy and foggy, and there were traces of cavalry running around. "The enemy is getting closer and closer, and they are observing the formation of our army. Wuqiao, when do you think they will attack?"

The fog in the morning is very thick and it is not far from rain.

Deng Zilong shook his head. He had no experience in fighting with the Northern Lu. He just said carefully: "They will definitely attack when the heavy rain first arrives; but the Northern Lu have defeated all the previous attacks, and maybe they will attack for a while when their troops gather."

"Is the caltrop cloth on the bridge ready?"

After receiving the affirmative reply, Chen Mu felt a little relieved. The cavalry in the fog on the other side was like ghosts coming and going without a trace. From the beginning of the enemy's cavalry crossing the border, they would occasionally scream at night, bringing great pressure to the defenders.

Chen Mu stood on the Wangstower and counted the defense again. From the caltrops on the bridge to the deer antler fence on the shore, he even asked mines wrapped in leather mixed with gravel to buried beside the bridge, and the fire line was wrapped in bamboo, but not too much - the weather was very turbulent, and it might not be useful when the rain was raining.

Except for the well-waterproof and well-structured artillery positions and gunner trenches, all the firearms outside are not enough to rely on.

"How many small flag arrows are there?"

The three hundred-house bird gun teams had all entered the trenches. It seemed that the flag army was quite used to such defense. When he heard Chen Mu ask, the hundred-house answered: "General, there are sixty small flag arrows, enough to hit twice."

"This is different from fighting in the south. Don't fight so many times at a time. When you see the enemy cavalry attacking the bridge, you can only send five small flag arrows." Chen Mu took a deep breath, pointed to the bridge and said to the flag army: "This battle cannot be won in an instant, it will be fought for a long time."

When the southern troops arrived in the northern border, it was difficult to change their offensive and defensive strategies because of the different situations of the flag army. The same was true for Chen Mu. The small flag arrows they used to kill the enemy in the south would probably only play a role in disrupting the enemy cavalry in the northern border. If they fought out in a swarm, they would not have much effect.

Before the war, he fought against the unknown enemy. Even Deng Zilong, who had been through the battle for a long time, became talkative and toured his position again and again. Chen Mu was the same, but he pretended to be calm and kept pulling Deng Zilong and Hu Daxiong to chat and laugh in front of the formation, and seemed to have no worries about the current enemy.

In fact, every time he turned around in front of the formation, he would drink a large pot of water when he returned to the military tent. The lack of sleep caused blood to rise in his eyes. In order not to be seen, he often squinted his eyes when outside the tent.

We have returned to the past state, with similar forces, and more than half of the friendly forces lacking training, accounting for 80%!

Three days, three days pass in a blink of an eye.

There were more enemy cavalry roaming on the other side, and sometimes they even saw a large group of cavalry roaming on the shore, and their morale was even more depressed. The flag army, which had never fought against the cavalry, placed wooden carvings in the trenches and bowed again and again. The riders sent to the other side only came back more than 300, and more than 100 people were killed in the encounter with the enemy scouts.

The remaining 300 people came back alive not because they won the victory in the encounter, but because they were lucky and did not encounter the enemy.

The heavy rain still did not fall, but the seemingly fog became heavier in the morning and evening. It was difficult to see clearly even with a telescope a few hundred steps away. However, Chen Mu could feel that the large group of people had lined up on the other side, and sometimes the singing from the grassland could be heard into their ears.

In order to arouse morale, Chen Mu would sometimes lead his family troops to lay a few guns on the other side of the shore. It would be another matter whether he could hit the enemy. The purpose was to let the flag army see him and not be afraid, so that the flag army under his command would not be afraid.

The fear in my heart is the more terrifying opponent in war than the enemy.

On the morning of the tenth day of September, the sound of horns finally sounded on the other side.

"Enemy attack!"
Chapter completed!
