Tongguan is bordered by the Yellow River in the north and cliffs in the south.

Coming from the Yellow River, the road near the city wall was even more steep, allowing only seven or eight people to pass side by side.

At this time, a burst of spring thunder suddenly sounded in the sky, followed by dark clouds, and a very strange sound was made as the wind passed through the valley.

After a while, a fine and dense light rain began to fall on both sides of the Yellow River.

Li Longji had already followed the army to the beachhead outside Fenglingdu.

The 130,000 heavily armed Fan Yang and Hedong coalition troops had already lined up their positions, exuding a cold murderous aura.

These soldiers were all active in the Tang Frontier, and they had all experienced countless life-and-death battles with foreign races.

Whether it is more than combat experience or more than the will to fight, the Beiya Forbidden Army under Li Mao is far from comparable.

However, the Northern Ya Forbidden Army was still full of morale in the face of a strong enemy.

Because Tongguan natural insurance gave them great confidence.

Knock knock!

Li Mao heard the enemy's war drums begin to beat, and then the army of more than 100,000 began to change formations.

Hundreds of tall and strong men in armor began to walk steadily along the mountain road towards Tongguan.

As the distance closes, so does the road.

A quarter of an hour later, when the enemy army reached the city wall of Tongguan, the width of the road was only enough for seven or eight people to walk in parallel.

"Hahaha, don't be afraid, the enemy army can only have a maximum of ten people to attack the city!"

Li Mao looked at the city wall and laughed.

Even though the enemy army was only 500 men, the winding road still made the line a mile long.

Moreover, it took half an hour to climb the mountain, and the enemy troops in heavy armor were already exhausted and out of breath.

How can you still have the strength to climb the wall more than ten meters high?

Woohoo.

The arrows pierced the sky and headed towards the enemy as they prepared to build a ladder.

Under the gaze of all the Beiya forbidden troops at the head of Tongguan City, all the arrows hit the enemy's steel armor, and there were no casualties.

With the exception of one or two unlucky guys, who were shot in the eye, none of the hundreds of enemy troops fell.

Li Mao didn't panic at all when she saw this.

"Soldiers, wait for the enemy to build the ladder and start climbing the city wall, and then smash it with rolling wood and stone gold juice!"

After receiving the order, the Northern Ya Forbidden Army immediately made preparations and quietly waited for the enemy army to approach the city wall.

Gao Shun presided over the defense of Tongguan for a month, and there was no waste in the slightest.

The supplies needed to defend the city were piled up at the head of the city.

Even the area in the city near the city gate was full of fortification materials.

Now.

The inexperienced soldiers of the Hedong Fanyang coalition army also set up the ladder, and seven or eight people staggered to push the ladder towards the city wall.

But where would the Beiya Forbidden Army, which had already been prepared, let them easily approach the city wall.

Boulders were thrown down with rolling logs, and even more began to pour gold juice out.

On the bank of the Yellow River, Li Longji's high platform was erected again.

He climbed up again.

After seeing his soldiers tossing and turning for nearly an hour, without even touching the city wall, his face was covered with dark clouds.

"Guys, is there any way you can break through Tongguan as soon as possible?"

Wang Yu immediately spoke: "Your Majesty, whether it is Hangu Pass in the Warring States Period or Laotong Pass in the Han Dynasty and Han Dynasty, they are very dangerous places, and it is extremely difficult to break through from the front. ”

"At the end of the Qin Dynasty, the world was in turmoil, even if it was Liu Bang, the ancestor of the Han Dynasty, could only look at the pass and sigh under the Hangu Pass, and then took the Wuguan Pass through Nanyang to finally take the Guanzhong."

"In the sixteenth year of Jian'an, Cao Cao led his army to attack Tongguan, Ma Chao and Han Sui in the west. Although the battle also broke through Tongguan, Cao Cao did not attack, but launched an attack from the mouth of the Wei River behind Tongguan from Pubanjin. ”

Wang Yu's meaning is obvious, that is, it is impossible to break through Tongguan head-on.

Li Longji also panicked when he heard this, and hurriedly said: "Then let's also send a large army to detour through Wuguan, or detour through Hantong Pass again." ”

Just now, he received an urgent report from Luoyang.

Pinglu had an accident, and Jiedu prevented Wu Zhiyi from coming.

According to reports, An Lushan, the governor of Yingzhou, and Shi Siming, the military envoy of Pinglu, took advantage of the festival to make Wu Zhiyi lead the army to King Qinwang of Luoyang.

They united with the Murowei and the Yan tribes to rebel and accepted the canonization of the Chang'an court.

Now An Lushan is the self-proclaimed Pinglu Jiedu envoy, and Shi Siming is the deputy envoy of the Pinglu Jiedu.

The two of them were leading the army towards the Fanyang area.

After Wu Zhiyi got the news, he could only lead his troops back to quell the chaos.

After all, the soldiers in his hands are all locals in the Pinglu area, and even if they are forced to Tongguan, the soldiers will know that their hometown has been beaten, and they will have no heart to fight.

Li Longji couldn't help but feel sick when he thought of An Lushan's pig-like fat figure.

In my heart, I am still glad that I have the wisdom to know people and did not accept An Lushan's refuge.

"The army can't be deployed here, and we have to find other places to attack together."

Fan Yang Jiedu made Zhang Shouqi not want to spend it like this.

At this time, it was just the beginning of spring, and there was no need to worry about the Turks going south.

If by the end of summer, the troops have not returned to Fanyang to defend, then the Turks will never be able to sit back and watch the success or failure on the steppe.

A large army will definitely be sent south to plunder.

And he also has a worry, that is, he is afraid that Li Mao of Chang'an City will join forces with the Turks and Hui to cause turmoil.

When the time comes, the soldiers of the entire Fanyang and Hedong will all have no fighting spirit.

"We must put down the rebellion by June, or the frontier will surely be in flames."

Wang Yu is also worried.

His hometown of Taiyuan was close to the Turkic territory.

If the Turks invade, he will be the first to lead his troops back, even if it is the emperor's order, he will not care.

After all, the Hedong Wang clan has been inherited for nearly a thousand years, and dozens of emperors have changed halfway.

As long as you can keep your hometown, it's a big deal to change the emperor when the time comes, and it's not impossible to call Li Mao a minister in Chang'an.

Anyway, he, Wang Yu, can be regarded as worthy of Li Longji's promotion.

"Alas!"

Li Longji looked at Wang Yu in front of him and sighed in his heart.

He didn't know what the local clans were thinking.

These families don't care who the emperor is at their head.

Especially after the new imperial examination system came out in Chang'an, most of the families secretly sent their side children to sign up, wanting to step on two boats.

There are three main forces in the Tang Dynasty, namely the Guanlong aristocracy, the Shandong scholars, and the Jiangnan Chinese.

The Guanlong military aristocracy originated from the eight great generals of the Zhu State during the Western Wei Dynasty, and was also the foundation of the Sui and Tang dynasties.

Li Hu, one of the Eight Pillars, was the grandfather of Tang Gaozu Li Yuan, the great-grandfather of Tang Taizong Li Shimin, and was posthumously named the Duke of Tang after the Western Wei Dynasty of the Northern Zhou Dynasty.

The development of the Guanlong military group to the Kaiyuan period, it was represented by Jingzhao Wei's, Jingzhao Du's, Hedong Pei's, Hedong Liu's, and Hongnong's Yang's.

Among them, Hongnong Yang was almost uprooted by Li Mao because of the military ration incident.
