Ignorance is the greatest enemy of mankind. At the same time, ignorance is also the cause of stupidity.

In the history of human development, war has always played the absolute driving force for the development of science and technology civilization.

The original intention of any new thing is mostly to cope with war and to enable oneself to gain a huge advantage when facing the enemy.

Any new thing that has been recorded in history and brought huge benefits to one side of the war originated from the ignorance and stupidity of the enemy.

The 50,000-strong Tibetan army was completely wiped out. The news reached the Tibetan holy city, but did not attract the attention of the city of Lhasa.

On the contrary, because of Galzanzhuo's generosity and defense, more people embarked on a path of no return.

Galzanzhuo began to mobilize the army of the Holy City, even including the only two remaining kings of the Seven Kings of Tianchi, and began to gather troops to march to Dafeichuan.

These are what Li Hong wants to see. If the army of Luoshui City does not come out in full force, how can he occupy Luoshui City as if he were in an empty place?

Heichi Changzhi continued to move south, resting and setting up ambushes on the only route to Dangxiang.

...

...

As for who will suffer this time, Li Hong has no idea.

Langri Songtsen, a general who was also famous in Tubo, now had his troops stationed in Dafeichuan, confronting the army led by the Tang generals Pei Xingjian and Yuan Shuji.

The area between Dangxiang and Bailang is deserted, which is why Li Hong looks down on this place now.

War horses, water and grass, cattle and sheep are what Li Hong wants, but with the current strength of the Tang Dynasty, it is probably more difficult to stabilize the four directions and control most of the Tibetan areas as easily as with one's own arm than to ask the Tibetans to develop explosives.

On the entire land belonging to the Tang Dynasty, Li Hong believed that what the Tang Dynasty lacked the least was mountains. Mountains were like the abbreviation of the entire land of the Tang Dynasty.

Even in the Central Plains, there are dragon-like mountains lurking in every province and state.

Tuyuhun owned Qinghai, which has always been called the Blue Sea by Tubo and Tuyuhun.

It is formed by the fault between Datong Mountain and Riyue Mountain in the Qilian Mountains and Nanshan Mountain in Qinghai.

Today's Qinghai Lake is more than twice as large as the Qinghai Lake Li Hong had seen in his previous life. It seems to have no end in sight, so people have to call it the sea.

From here, Li Hong could gallop eastward across the grassland like a fork and go straight into the rear of Langri Songtsen's troops.

Fuqi City, as the royal capital of Tuyuhun and the symbol of Tuyuhun, has now been built more perfectly by Lu Dongzan.

The fact that the Tuyuhun people have no regular taxes is what they are most proud of. Only when necessary will the country collect taxes from wealthy nobles and royal merchants and then replenish the national treasury.

The Qinghaicong should be a better horse for fighting, but because the Qinghaicong is not as numerous as the Tibetan horses and the Turkic horses, when selecting war horses, Li Hong still took an economic perspective and equipped the troops with the cheaper but equally capable Turkic horses.

Li Hong wanted to recapture Tuyuhun, and he had his eyes on the Qinghai Cong. The dragon breed was also good, but it was far inferior to the Qinghai Cong in terms of endurance, and was not suitable for the army to fight for a long time.

Sitting by the Qinghai Lake and fishing leisurely is definitely a complete enjoyment for Li Hong.

But to Wufawutian and Quan Yi, this was a provocation from the Grand Protector to Langri Songtsen, who was thirty miles away.

Wufawutian and Quan Yi were too busy to go fishing with Li Hong. Thirty miles was neither far nor near. If the enemy launched an attack, they could almost certainly attack you before you had formed your formation.

But the Grand Protector Li Hong was obviously not worried at all, and seemed to be eager to let Langri Songtsen notice his presence.

After setting up camp on the shore of Qinghai Lake early this morning, Li Hong was in a very happy mood.

After helping Li Hong take a bath, Banmei and Xunlan started to go fishing with him.

After not taking a shower for many days, the two girls felt like they were going to stink, so today they naturally rubbed the soap all over their bodies as if it were free.

Even when helping Li Hong bathe, the two women were eager to give His Royal Highness the Crown Prince a few more bars of soap.

When the two women served Li Hong in the bath, although they were already used to his naturally erect penis, every time they looked at it, their hearts would tremble involuntarily, their bodies would feel hot and weak, and they wished that His Royal Highness the Crown Prince would ask them to accompany him immediately.

And the Crown Prince's hands seemed to have magical powers. When they were serving them in the bath, they would touch their bodies from time to time, making the two women tremble all over.

They couldn't help but moan softly, their cheeks flushed, and their eyes seductively followed the Crown Prince's big hands that moved up and down their bodies.

Bai Qi lazily leaned his huge head on Li Hong's arms, and then his wolf eyes began to stare at the fishing rod.

"You said you don't eat fish, so why are you staring at the fishing rod in my hand? Do you want to send some fish to your accomplices?" Li Hong was fishing with one hand and stroking Bai Qi's head with the other hand out of boredom.

Bai Qi yawned with his mouth wide open like a dog, then stood up, shook his shiny black hair, and walked away quietly.

"Master, what should we do now? Just wait for them to come find us?" Quan Yi unconsciously began to follow Hua Meng and others in calling Li Hong like this.

"There are still two days left. Pei Xingjian and Yuan Shuji have been making trouble here for more than a month. They are just shouting and not attacking. I don't know if Langri Songtsen has become careless." Li Hong slowly put his upper body into Banmei's arms, found a comfortable position, and said with his head resting on Gao Mei.

"Cheetah has already gone there secretly. Two days later, Pei Xingjian and Yuan Shuji will be the main attackers. We only need to harass the defense for one day." Li Hong glanced at Quan Yi, who was very handsome.

No wonder Yi Yang asked Bai Chun to pass on a message, saying that if anything happened to Quan Yi, be careful that the newly built Prince's Mansion would be burned down by her.

"Master, what about us? After the battle of Dayuechuan, shall we go directly into Menyuan from here? Or...?" Banmei looked at Li Hong's cheek. Although she was in the Western Regions after following the Crown Prince for several years, she felt much more comfortable than in the imperial palace.

"Of course we won't go back to Menyuan. Alas... this is how life is. There are always some things that you have to do. Next, when the Tubo troops chase us, we will fight our way back to the Tubo royal city, and then return the same way." Li Hong looked at the clear Qinghai Lake and felt like he was in a daze.

He had to visit the holy city of Tubo. Otherwise, after spending so much time in Tubo, it would be hard for him to say that he had won a great victory.

What's more, his goal has not been achieved yet. After he occupies Lhasa City, Dai Zhide and others will be sent here by Yuan Shuji. Next, Dai Dabanchui will start teaching and educating people here and spreading the culture of the Tang Dynasty.

Wars always take place at night. When Langri Songtsen looked up for the first time, wisps of green smoke were rising from the shore of Qinghai Lake.

When I looked up the second time, the smoke had not dissipated yet.

But when night fell, he saw the rumbling sound of horse hooves, shaking the earth like a gust of wind on the grassland. In the blink of an eye, the Tang soldiers had reached the trench he had built.

The nervous voice of the messenger made his heart tremble. The Tang soldiers in front of him actually launched an attack as well.

Langri Songtsen did not appear to be panicking. Moreover, as long as he could hold on through tonight, reinforcements from the Holy City would arrive tomorrow. By then, it was still unclear who would attack whom.

However, the ferocity of the Tang cavalry was far beyond his imagination. Although the trenches they built blocked part of the attack of the Tang cavalry, the bows and crossbows in the hands of the Tang soldiers passed over their heads with a sound of breaking through the air.

Then, he heard screams, the sound of arrows breaking through the air, the neighing of war horses, and the cries for help from the troops in the front, which forced Langri Songtsen to frown at the beginning of the war.

The Tang soldiers in the front were attacking with a roar like thunder.

However, the Tang people in the rear fled without any hesitation, just to delay the troops behind so that they could rush to the front to reinforce.

The balance of victory and defeat was tilted from the very beginning. Before the sky became bright, the ground outside Fushi City was already littered with corpses, and arrows, lances, swords and other weapons were scattered all over the ground.

Li Hong and his troops disappeared without a trace. Langri Songtsen stared blankly at the dawn sky. He had not expected that he would be defeated so quickly.

He never expected that the city gate would be breached after a thunderclap, and he never expected that these Tang people not only failed to break the city, but instead just killed people.

With 170,000 soldiers and horses, they were unable to hold the city when faced with less than 90,000 Tang troops attacking the city!

This made him unable to figure out what caused him to lose the battle.

A large number of captives were taken away by two young and handsome men, and Langri Songtsen only vaguely heard the conversation between the two men in the wind: "Brother Ming, from today on, this cement will be enough to meet the expenses of the four towns of Anxi."

"Yes, Brother Du, in today's battle, my Tang Dynasty was able to capture so many prisoners. This is all thanks to the Crown Prince." Ming Chongyan looked happy and mysterious.

The cement production has not increased in the past two years, and both he and Du Yuanji are under great pressure.

Moreover, the four towns of Anxi are basically empty cities now. Except for Xue Rengui in Shule City, the other three towns have basically no soldiers to defend and their gates are wide open.

If he did not speed up the production of cement, the White Arabs or Tubo would easily break through before the four towns were built into impregnable cities.

Fortunately, Suiye is now almost the first to be completed. The thick and towering city walls are made entirely of cement and stone. The black and cold walls give the enemy a strong sense of oppression when they stand there.

Yuwen Rong and Liang Xiaoren, who had just finished urging them to deliver cement in Suiye, started urging the two in Yutian to deliver cement as soon as possible.

"Let them treat us to dinner next time. Last time, the two guys didn't even take us to see the Hu Ji show, but took away our ten thousand slave laborers." Du Yuanji got angry whenever he mentioned Yuwen Rong, the stingy man.

"Looking for Liang Xiaoren, but last time when you were drunk, you said that it was unreasonable for others to spend money in Menyuan, so you had to do your duty as a host." Ming Chongyan's handsome face was relaxed. With so many captives, he was enough to deal with Liang Xiaoren and Yuwen Rong who were urging him to make progress.
