Time Travel: I am the idle king Li Shen and Li Shimin in the Tang Dynasty

Li Shen did not go to the main battlefield, but ordered people to bring tables and chairs, and found a good seat for the horse-faced warrior to sit down.

From this place you can use a telescope to see the situation on the Wengcheng battlefield.

Li Shen would never go to such a dangerous place.

There were arrows flying everywhere and I was not wearing any armor. If I was hit by a grenade, I would be doomed.

Li Shen never does anything risky.

"Come on, Fourth Brother, Ninth Brother, sit down and have a cup of tea to calm your nerves."

After sitting down, Li Shen spoke humbly to Li Tai and Li Zhi.

"Li Shen, it's already this late and the enemy is attacking in full force. You need to think of a countermeasure quickly. The eastern city wall is about to be lost.

Do you still have the leisure to drink tea here?"

After the two sat down, Li Zhian couldn't help but shout to Li Shen out of worry.

"Brother Nine, please be patient. I have already sent people to the east city wall. Those Westerners in the city have been cleared out. Nothing will happen."

Li Shen poured a cup of tea for the two of them and said calmly.

"Where did you get your troops?" Li Tai was a little confused.

"The troops from the Protectorate." Li Shen said confidently.

"Weren't you sent out to rescue His Majesty? We saw it with our own eyes. Oh, and we saw you were also in the team at that time.

Why are you in the city?"

This was the most puzzling thing for them. They clearly saw Li Shen following them, but why did he still appear in the city?

The main reason they dared to conclude that it was Li Shen was because of Xiaobailong.

Once a good war horse recognizes its owner, it will not easily let other people ride it. This requires a taming process.

"Let's talk about this later. Let's stabilize the battle situation first." Li Shen said, then took out a flare and handed it to Qin Huaidao.

Qin Huaidao came to the side, lit the fuse, and raised it above his head in everyone's surprised eyes.

"Chiu~~~Bang~~~"

With a muffled sound in the sky, everyone on the battlefield was attracted to it.

"Tenth brother, what are you doing..." Li Tai asked.

"It's nothing. This is called a cloud-piercing arrow. Thousands of troops are coming to meet you. Just wait and see, my two brothers."

Li Shen said this and then looked towards the battlefield.

"Look, what is that?"

"so big."

After a while, dozens of large balls rose from the west city and flew up slowly, one by one.

The Tang army in the city were all shocked when they saw the big ball. They had never seen such a thing before, especially something that could fly.

As the ball rose higher and passed the city wall, the enemy's reaction was even greater.

The ancients have always believed in ghosts and gods, and attributed things they had never seen to ghosts and gods.

They had never seen anything like flying before, and they were all so scared that they stood there in shock.

"This must be Tenth Brother's hot air balloon." Although Li Tai was surprised, he could also guess it.

Hot air balloons shone brightly on the Goguryeo battlefield. Although he had never seen it, he had heard of it.

Currently, only the Beiya Imperial Guards and the Prince Ji’s Palace have hot air balloons, while other armies do not.

Your Majesty will not hand over this kind of powerful weapon to outsiders for the time being.

"Fourth brother is right. It is indeed a hot air balloon. This time I came to Qinghai Road, I brought fifteen of them."

Li Shen nodded.

He didn't make too many of these.

Everyone looked at the hot air balloons. Because the wind was blowing from the west, the hot air balloons slowly floated out of the city.

If you look closely, you will find that these hot air balloons are connected to the ground by two ropes at the bottom.

This is also because Li Shen was afraid that the strong wind would blow him away.

Li Shen looked through the telescope and then gave Qin Huaidao a flare.

With a muffled sound.

The hot air balloon began to move like an egg, dropping incendiary bombs as it moved.

"Bang~" "Boom~"

These incendiary bombs are made of ordinary clay pots. They shatter immediately after hitting the ground, and the liquid inside splashes everywhere, followed by an explosion.

"Bang~" "Boom~"

"Bang~" "Boom~"

Suddenly, the battlefield outside the city was a sea of ​​fire, and the Tibetan army kept screaming in the sea of ​​fire.

"Alas, air strikes are indeed the key to victory or defeat in war."

Li Shen stood up and looked at the scene in the distance and couldn't help but sigh.

He didn't want to do too much research and development on weapons, not because he was kind, but because it was too dangerous for the rulers.

Li Tai and Li Zhi were stunned by such a scene.

They thought the siege they saw yesterday was a large-scale war, but what did they see now?

Li Shen picked up something at random and started slaughtering the enemy.

This was completely beyond their imagination.

They looked at each other and saw fear in each other's eyes.

Li Shen actually possesses such a powerful weapon, no wonder their father dotes on Li Shen so much.

"Okay, that should be enough, this wave will be enough to scare them out of their wits.

General Li, immediately give the order for everyone to cover their mouths and noses and clear out the enemy troops under the wall.

Although the wind is blowing from the west, there is no guarantee that the poison gas will drift over here."

Li Shen saw that the hot air balloon no longer dropped incendiary bombs and immediately gave the order.

He estimated that they had all been thrown away, but it was not the time to collect them yet, so he let them float for a while to serve as a deterrent.

At this moment, Yang Shaowei collapsed to the ground. He knew it was all over and the Tubo army could not attack.

His fate would not be any better.

"Tenth brother, what about the east city wall? Why don't we do the same..." Li Tai suggested.

"No, Fourth Brother, this incendiary bomb is poisonous when it burns. Now it is a west wind, although it can burn the enemy to death,

But when the wind blows, the poisonous smoke will be blown into the city.

Some troops have already been sent over there, and it will be no problem for some more to go over here later.

There shouldn't be many enemy troops over there.

The main reason is that we have no cavalry, otherwise we could have eaten them."

Li Shen felt a little regretful. Although he defeated the enemy, the enemy was on horseback and he could not catch up with them.

"Reporting to the Grand Protector, the enemy has retreated." A captain came running over to report.

"Yeah." Li Shen nodded and looked at Li Tai and Li Zhi.

"Fourth Brother, Ninth Brother, you must be tired. Now that the enemy has retreated, I will send someone to escort you back to the mansion to rest."

Hearing this, Li Tai shook his head:

"Old Ten, you haven't explained why you are in the city, and what is going on?"

This was what he wanted to know most. He once suspected that Li Shen had not left at all. Based on his understanding of Li Shen, how could he take the risk?

But he asked someone to check, but there was no trace of Li Shen.

"Fourth brother, this is a long story." Li Shen poured another cup of tea for the two of them.

"This story all started when my younger brother captured a Tibetan spy."

"Elaborate work?"

Li Tai and Li Zhi did not know or hear of these things.

"Yes, a spy. My people caught the spy and interrogated him.

Appealing to his emotions, explaining things to him with reason, and presenting facts and reasoning, he was eventually moved and revealed a person’s name.”
