The different pictures presented by the two perspectives brought strong pressure to Ji Ning's mind. The incarnation and the true body must maintain a state of movement and stillness in order to operate harmoniously.

Nowadays, the external incarnation may be able to enter the mysterious realm of unity between man and nature at any time, which makes Ji Ning dare not cut off the connection at will, so as not to miss the best opportunity, and it will be too late to regret it.

In short, his current state is pain and happiness.

On the other hand, after Ji Ning retreated from the court, he walked alone in the magnificent palace city. The vast amount of true energy in his body changed with his thoughts, sometimes with great waves, sometimes with calm and uncertain changes.

Every time the waves surge, they are slapping at the invisible door of wonder.

Ten days later, Ji Ning left the crown prince Yang Qing to guard Luoyang, and he led his army to attack Tongguan!

Since ancient times, the world has been dangerous!

Tongguan is located in Weinan, facing the Yellow River in the north and the mountainside in the south. It is the eastern gate of Guanzhong, and is the key to entering and exiting the Three Qins. Therefore, it has become a must-pass place for entering the Central Plains in the east and going to Guanzhong in the west since the end of the Han Dynasty. It has always been a place that must be fought for by military strategists. It has always been known as "the first danger within the capital", "the throat of the four towns", and "the hundred and two gates".

"This attack on Guanzhong is a big battle. In addition to the Li family, they will inevitably fight against the Turks!"

Ji Ning rode a tall horse and looked at the endless army, but a sense of pride rose in his heart. He had a premonition that the opportunity to step into the Tongxuan realm was in Daxing City.

"Wu Zun Bi Xuan, I hope you won't let me down."

Last year, when Li Yuan raised his troops south to Guanzhong, Xue Ju also raised his troops to rebel against the Sui Dynasty in Longxi, proclaiming himself the overlord of the Western Qin Dynasty, and his reign was Qin Xing.

Li Yuan had not yet pacified Longxi, and the Sui army in Luoyang to the east fought again. This was a real life-and-death crisis for Li Tang.

In this case, it goes without saying what choice Li Yuan would make.

"His Majesty!"

At this time, Wang Shichong rushed over, dismounted and bowed, saying, "The situation in Tongguan is dangerous, there is Qinling Mountains in the south, there is a forbidden valley in the southeast, and there is Wei River in the north. Luo Erchuan meets the Yellow River and walks down the pass, and closes to Huayue in the west.

The surrounding mountains are connected by mountains, peaks are connected by peaks, deep valleys and cliffs are narrow, high mountains and narrow roads are only connected by narrow paths, and the Little Valve has arranged heavy troops here. If we want to take it down, it will probably take more effort?"

"Oh?" Ji Ning glanced at Wang Shichong meaningfully.

"Your Majesty's Heavenly Soldiers will surely be able to win every battle, but this time the imperial army will personally fight, the first battle in Tongguan..."

Wang Shichong tactfully advised.

Ji Ning smiled and said, "What I said is reasonable, so in this first battle, I am going to send a surprise soldier to the battlefield and break through Tongguan, just between the backbone!"

"Your Majesty is far-sighted, I am not as good as you can." Wang Shichong said in fear and trepidation.

Under Tongguan, the Sui army set up a siege.

Ji Ning stepped forward and saw the city wall layout. He couldn't help but smile and said, "It seems that this guard is not stupid. I know who is the one who is strengthening the city wall layout?"

"Tongguan is the place where Li Ni lives and dies, and the one who guards the city is Li Yuan's eldest son Li Jiancheng!"

Wang Shisheng immediately said.

"It's a pity... despite the many arrangements, it's useless!"

Ji Ning waved his hand and ordered the soldiers to cheer up their cheeks, and the sound of the horn was transmitted from afar.

The Sui army separated and showed an army wearing red armor and flagged with fire.

Several teams roared and pushed wooden chariots into front of the formation. On top of the wooden chariots were several extremely large iron pipes. The gun body was dark and ferocious, which was the most common way for generals to artillery in later generations.

Of course, now, both the iron material used for casting and the power are enough to be considered a killer weapon.

Ji Ning summoned a group of alchemists to Jiangdu. In addition to refining "fire catastrophe" and "water poison", he also caused some things that were included in military secrets.

"Divine Artillery...prepare!"

Ji Ning came forward in person, commanded and calibrated the target.

Immediately, an artillery man filled the shells and lit the torch.

"put!!!"

Squirt!

The fuse was lit, and it was emitting blue smoke, and it quickly penetrated into the cannon.

Boom! Boom! Boom! Boom!

In the terrifying loud noise, an unparalleled explosion suddenly occurred on Tongguan!

The air flow was surging, the rocks flew, and the defenders were crying and howling!

All three armies were stunned.

"Heaven...Heaven punishment!"

Thinking back to the dazzling white light and the terrifying aura of destruction before, Wang Shichong couldn't help but murmur.

He looked around and saw chaos at the head of Tongguan city, several huge holes emerged, the edges were pitch black, and soldiers shouted and cried.

These artillery actually made several gaps in Tongguan! The frightening effect brought by these is even greater than the power of the shells.

"Silent! Form a formation!"

The commanders of the Sui army urged them for a long time to gather all the soldiers who were prepared.

Compared to the Sui army, which was slightly prepared, the army opposite was facing this scene that was as straight as the punishment of heaven. Many people directly collapsed their faith and started crying for their parents.

"Your Majesty is mighty and God helps you with this magical artifact!"

Wang Shichen immediately knelt down to Ji Ning and ordered the soldiers to spread this sentence everywhere.

"Long live my emperor!"

Among the three armies, there was a moment of dullness, and then there was a thunderous sound of joy.

"The God's artillery is launched again! Prepare to attack the city!"

Seeing that the morale was high, Ji Ning immediately issued an order to siege the city.

Under the continuous bombardment of the divine artillery, the Tongguan defenders were almost defeated.

However, the Sui army was very motivated and rushed forward with a roar, wave after wave, slowly swallowing the Guanzhong Pass.

Youniaojue, Zhou Laotan and a group of masters immediately rushed out, used their light skills to jump up to the city tower, looking for the most precious spoils.

By the time the sun sets, the setting sun is as bloody as the whole battle situation has completely stabilized.

"Report to Your Majesty!"

Wang Shichong did not care about wiping away the black and gray on his face, knelt down in front of Ji Ning's imperial guards, and said, "The general of Tongguan turned against him. Li Jiancheng was trapped in the mansion and struggled to break through. He was covered with more than 20 wounds and was shot dead by arrows. He accompanied him with fifty-seven elite soldiers, none of them alive!"

"Li Jiancheng died like this."

After hearing the news, Ji Ning was stunned for a moment, then sighed. After Tongguan was breached, the situation in Guanzhong collapsed and was right in front of him.

If Li Yuan hadn't had the Turkic thigh to hold, he would have been forced to surrender.

Above the Guanzhong Plain, a vast army was winding forward.

Ji Ning rode his horse and saw that the fields on the plain were continuous, mostly of the best cooked fields, with fertile soil. He couldn't help but exclaim: "The career of Qinchuan, the foundation of the emperor, and the ancients did not deceive me!"

The land of Guanzhong at this time was not the Loess Plateau with thousands of ravines in his memory.

On the contrary, the vegetation is lush and the place where you see is full of pleasant green, and the place where you see it is endless.

Before the water and soil were lost, the Guanzhong Plain was truly a fertile land, and regardless of population, politics, economy, and agriculture, it was a well-deserved "country of heaven".

After capturing Tongguan, Ji Ning led his army to Daxing City.

Actually, there is no choice.

If he did not seize the opportunity, Li Yuan would surrender to the Turks, and the entire north would be in ruins.
Chapter completed!
