Even if Zheng Song, the biggest minister of the Later Li Dynasty, was not in Yi'an, the guards also had their own thoughts about the Ming army's coming to help, and tried their best to probe Chen Mu's troops, but they did not find out the strength of Chen Mu's troops clearly, but let the Juniper sent by Chen Mu find out their troops.

The letters sent back in the early morning seized the moral high ground everywhere, and the words were good, but the meaning was also very clear.

The Ming army came to 'correct the name to distinguish the obedience', not only looking forward to Chen Mu's troops, but also not wanting the Ming army to occupy the place.

The letter made Chen Mu laugh, and said with a smile to Zhang Shijue: "Can Chen say this by himself, can they say it?" ”

In any case, Hou Li had an army of 30,000 in Yi'an, while Ruan Ti only had 20,000, and on paper Hou Li had the advantage of troops, but the situation was obviously that Ruan Ti was invincible and plundered all directions.

"The letter said that Ruan Ti had met with them once, killed hundreds, and captured the commander of Yi'an, Hongjun Gong, and frightened the Houli army into defeat, and the generals Pan Gongji and Zheng Mo had no choice but to set up a village in the suburbs of Yi'an to resist the enemy."

"Three days later, Pan Gongji will lead the army to fight again in Ruan, I will lead the Ding Banner army to attack its flank, and you will escort thousands of troops with artillery to protect my back road." Chen Mu took a deep breath and spit out heavily, saying, "If they are afraid of being beaten by Ruan Ti and dare not pursue, you are my palace army." ”

Zhang Shijue clenched his fists heavily, and immediately said: "Two thousand, Ruan Ti has 20,000 men and horses, and Annan has been fighting for a long time, is there a little less troops?" ”

"Less, of course less!" Chen Mu chuckled lightly and said: "Chen can't wait to wave 200,000 troops to beat him 20,000, isn't this a total of 4,000 soldiers in his hands, and he has to leave 800 soldiers to watch the ship and make artillery, so he really can't free up more troops." ”

"There are warships and heavy artillery, five miles along the coast is my territory, you fortify in seven miles, I am nothing more than leading troops to walk three miles to meet the enemy." Chen Mu kicked the sand and looked to the west, and said: "This victory is not in me, but in Li General Pan Gongji, as long as he dares to fight, this battle can be won." ”

"As long as Ruan Ti is not a blind cat and a dead mouse will stand in front of me, at most 5,000 soldiers on the flanks, even if they all turn their backs to me, 5,000 soldiers, what is there to be afraid of."

Sai Donkey's words were actually encouraging himself, and he waved his hand and said: "Send a fleet to inform General Deng of the battle here, if the enemy army is defeated in a battle, let him be prepared; By the way, if you can find General Lin's words, I will also say it. ”

Just like Chen Mu thinks, for the disputes between the North and the South, Yi'an and Tongzhou are both big rear, and the really fierce front is fought to the death in the radius of 250 miles between Thanh Hoa and Thang Long.

Ruan Ti dared to lead his troops deep into the hinterland of the Li Dynasty, and threatened Yi'an with less, so he must have the ability.

In the face of such an enemy, it is impossible to be too cautious.

In the past three days, with the help of sea boats, the flag army has almost clearly mapped and mapped the surrounding terrain, not to mention the details, but the general terrain has been clearly understood.

Yi'an has a mountain range that stretches for more than 30 miles from northwest to southeast, and the foot of the mountain falls in the northwest of the city; There is also a mountain range in the north of Fucheng more than 20 li, the foot of the mountain is directly connected to the sea, and the two mountain ranges form the narrowest canyon in the northwest of Yi'an.

The 20,000 army camp of the Northern Dynasty general Ruan Ti fell in the valley, guarding the widest artery leading from the city of Nghe An to Tongzhou and Thanh Hoa, cutting off traffic.

Before the battle, Chen Mu led Zhang Shijue, Jun Song and others to ride lightly in the middle of the North Mountain of Yi'an, which was no more than two miles narrow, to climb the North Mountain, and look at the surrounding terrain, where he also understood why Pan Gongji's 30,000-strong army could not defeat Ruan Ti's 20,000 horses.

They were blocked, and if they wanted to fight Ruan Ti, they would either go around the difficult valley road under his feet, which only the remaining small army slowly passed, to the north of Beishan, and travel more than 30 miles to attack Ruan Ti's belly and back; Either you can only fight with Ruan Ti in the valley of prayer.

Such a geographical advantage was seized by Ruan Ti, and as a result, only Ruan Ti beat them, and they did not attack Ruan Ti.

There was also a battle when climbing the mountain, Ruan Ti did not set up a large army in the Beishan Valley, only a few scouts were left to guard the canyon, they found Chen Mu and his party, Chen Mu also found them, Zhang Shijue Jun Song and others led the bow to shoot them, and they also injured two family members.

Zhang Shijue said: "The Northern Dynasty Ruan Ti stayed here as a scout, and he should rob and kill the messengers, not to worry about the passage of the army, and tomorrow I will wait for the early dispatch of troops to pass through the canyon." ”

Chen Mu nodded and smiled: "He estimates that he can't wait for Pan Gongji and others to lead the army into the valley, there are few soldiers and there is no need to worry, and if there are many soldiers, the city will be empty, and he can take advantage of the situation to occupy the city - success or failure is tomorrow, pull the cannon up tonight." ”

"Around the Beishan Valley, that is, guarded by your department, and take care of this road of life and death for Chen!"

The next day, the sea fog was thick in the early morning.

The fog was in their favor, and the 3,000-banner army entered the gorge, and on the west side of the North Mountain, there were 33 Chen Bu artillery, just waiting for the battle.

The morning fog has not dissipated, and it can be seen that there are less than 200 paces around, and the faint sound of military footsteps came from the right side of the mountain, which made Chen Mu change color, and the flag army was ordered to garrison while the army was silent.

That direction is the Ruan Ti camp, whether the Yi'an army will send troops Chen Mu does not know, but what he can be sure of is that the Ruan Ti army has moved!

This made Chen Mu suspect that Li Nanchao was afraid that someone in the city of Yi'an Mansion had leaked the news.

However, Ruan's target was not him.

At the second quarter of the morning, the sun was rising, the sea fog was beginning to disperse, and Chen Mu was in a solemn scene under the telescope.

Pan Gongji according to the agreement, early in the morning by the sea fog did not disperse, led the army out of the city of Fucheng soldiers divided into three roads, to occupy the geographical advantage, at this time in the east of the Qishan Chen soldiers four or five thousand dignified array, the northeast of the city near the coast also has a cavalry battle formation standing in the field, together with the army of nearly 15,000 people.

From a distance, Pan Gongji's Chinese army has ten war elephants standing in front of him, there seems to be a small cannon on the behemoth saddle, the war elephants are waving flags left and right, and the sea fog is scattered and the drums are ringing in unison!

Obviously, Pan Gongji moved out of his family, and there was a riot in their military formation.

The sea fog dissipated, revealing the situation under the North Mountain, not the surprise of the Ruan Ti camp in the canyon they imagined, but the neat and tidy soldiers of the Northern Dynasty Ruan Ti, the army was divided into four formations, one of three thousand, and one 12,000 soldiers stood with their backs to the North Mountain, and the same moment of mutual discovery only brought a temporary panic to the Ruan Ti army.

Immediately after, the clamoring of military music resounded throughout the field, and the two armies invariably chose to set up their formations on this day, with an interval of more than ten miles, and neither of them took the lead in sending troops.

Compared with the strength of the Southern Dynasties, the armament of the Northern Dynasty army under Ruan Ti is more advantageous, although Ruan Ti does not have elephant soldiers, but nearly half of the troops are armoured, each array has fire guns, bows and crossbows, long soldiers are the majority, spears, boring handles, axes, knives and even halberds.

Chen Mu also found that each of the four arrays had five small cannons placed on wooden frames.

It's too far away to see the shape of the system, but it looks like it's either a Francophone or a haircut.

Chen Mu understood, he really didn't have to worry about not knowing the weapons of the Annan Kingdom, what the Ming army used twenty or thirty years ago, what was used, it was nothing more than fewer cutting-edge firearms and more miscellaneous cold weapons.

Each formation in the Nguyen Ti army released the general Pegasus to run in front of the formation, there were superhuman people with dual wielding swords, and there were also Vietnamese little Wen Hou wielding Fang Tian's halberd, which looked like they were calling for battle.

Chen Mu was stunned.

The most divine thing is that Pan Gongji really sent several horsemen, each holding a sword, axe, and a horse to meet him.

The donkey man who could see the telescope on the mountain and watch the battle leisurely widened his eyes, handed it to Juniper and exclaimed: "These people have seen too much of the Romance of the Three Kingdoms, I have never seen anyone fight like this in the Ming Dynasty!" ”
