Back to Lulong City.

Shen Buyi's mood is a bit complicated.

This Yilagu must take action when he rushes back.

Now he reflects on himself and looks at the problem, and seems to be too idealistic and too focused on me. He is still a novice in the war. Therefore, now facing the Goguryeo army that has lost Yi Lagu, he must be strong and twelve points.

The next day, it was dim and Shen Buyi quietly appeared in the bushes not far from Shanhaiguan.

Outside Shanhaiguan, facing the northern nomadic peoples, it is built along the mountain. It is extremely steep and easy to defend but difficult to attack.

The abdomen faces the Central Plains, and the terrain is much flatter.

Now the army of Goguryeo is camping on Shanhaiguan.

It is unrealistic to eliminate all of them, and it is still feasible to force the Goguryeo army out of the pass.

When he returned to Lulong City, Chen Buyi came to ask his father again.

Chen Junru shook his head slightly, "Let's wait for Xu Guang's army to come. Don't look at their military camp outside the city, but once the fight starts.

They retreated to the lockdown and we had nothing good to do, right?"

Yes, in this era of cold weapons, the city is high and the walls are hard, so it is difficult to break through.

"There is no good idea, so keep setting the fire."

If you set the fire, you will find the sweetness, so you must continue to try it.

Chen Junru continued to shake his head, "No, no."

When you burned the Khitan military camp, it was because the enemy was not guarding, so you succeeded by chance.

But you see, now there are mobile posts five miles away, Lonely Hills three miles away, and there are secret posts.

This is obvious, to prevent the enemy from sneak attacking and setting fire.

After listening to Chen Junru's analysis, Chen Buyi was a little stunned.

That's really the case.

But, you can't just give up.

After thinking about it, Chen Buyi suddenly slapped his head and started to work hard.

First, I ran to the yard, found a few bamboo poles, and peeled off the thin bamboo slices.

Then he ordered someone to cook a pot of noodle soup.

White noodle soup.

.

I went to the study again and brought some paper out.

Chen Junru was a little stunned.

"You, what are you going to do?"

Chen Buyi smiled, "You will know then."

After a busy work, Chen Buyi actually made a large Kongming lantern.

He also suddenly felt inspiration. He had participated in some school activities many times, praying for blessings, and sometimes arranged the Kongming lanterns to be put on.

However, when putting it, pay special attention, because many Kongming lanterns will eventually burn into a fireball and fall down.

This is a good way to set fire.

According to the situation found in the morning, the Kongming lantern must be lit at least eight to ten miles away.

Therefore, how much tung oil is added during this burning time requires repeated experiments.

As a result, a large open space outside Lulong City became a difficult test site.

Fortunately, I brought enough staff.

Some people are responsible for making lights, some are responsible for measuring distances, Shen Buyi stands above the city. Observe carefully and record every flight data, and even the impact of wind speed.

Seeing the qualifying prince-consort and the newly promoted general of the Martial Arts, he actually played Kongming lanterns. Although the defenders did not say it, they could not help but feel disappointed.

Is this coming to fight or vacation?

In the strange eyes of these people, after a day of repeated experiments, Chen Buyi finally confirmed an accurate data.

The Kongming lantern made from this value is about fifteen miles away. It can not only avoid Goguryeo's open and secret whistles and put its soldiers in a relatively safe environment.

Also, this distance is within your own line of sight, and you can see the specific situation of the enemy camp and make adjustments at any time.

So, the next day, the thousands of people brought by Chen Buyi began to make Kongming Lanterns in an orderly manner.

This time, even Gao Qun couldn't stand it anymore.

My expectations for Xu Guang were even stronger.

At this time, after leaving Qingzhou Prefecture for 200 miles, Xu Guang used the excuse of slow action in the army, which might have missed the opportunity to fight.

His life Changbao led 5,000 troops, light and simple, and went to Shanhaiguan to provide assistance.

After Chang Bao took the people out for dozens of miles in one breath, he got into the mountains.

Then, in groups of three or three, the scattered peddler and the rich young man walked out of the mountains.

Five thousand people and horses separated quietly.

The next day, Xu Guang ordered his son Xu Qing to rush to Shanhaiguan again with three thousand troops.

Three days later, less than 5,000 people were left beside Xu Guang, protecting the food and grass, and slowly strolling towards Shanhaiguan.

.

.

.

.

.

.

Night falls.

Shen Buyi is here.

Gao Qun was a little surprised.

I don’t know what this prince-in-law, who has been busy with Kongming lanterns, wants to do.

"Nothing to do, we will attack the enemy at night tonight and have good luck, and we will be able to take back Shanhaiguan.

.”

Chen Buyi said it lightly.

Gao Qun was stunned when he heard this.

"Monkey King Chen, you don't know. Before, I had organized night attacks many times, but they all failed."

Chen Buyi smiled slightly, "That's because I didn't come, so you failed."

All right.

Gao Qun smiled helplessly.

"I don't know how many soldiers Gao wants to send out."

Chen Buyi smiled unfathomable again, "Han Xin ordered the troops, the more the better."

The sound of the bangzi in the fourth update passed.

With the command of Chen Buyi, countless bright lanterns slowly rose, illuminating half of the night sky, and slowly drifted towards the Goguryeo army camp under the blow of the small south wind.

Gao Qun was stunned.

Is there a light to light this night attack?

Chen Buyi smiled and shook his head, "You will know soon."

Such a huge Kongming lantern army also alarmed the Goguryeo camp.

Park Hui and others were sleeping in a daze, but were suddenly woken up by the sentry and said it was dawn.

Park Hui was a little confused. Isn’t it just the fourth update?

Put on a sheepskin coat and walked out of the tent to take a look, right?

A large ray of light from afar moved slowly towards them.

In Goguryeo, there is no such thing as Kongming lantern, so these people were all staring at it, not knowing that they would soon experience a tragedy on earth.

When the Kongming lanterns floated above the military camp, they turned into fireballs and landed.

At this time, Park Hui woke up like a dream.

No, please put out the fire quickly.

But it's too late.

The same problem is still the same. The weather is dry and the big tents of the military camp are mostly combustible.

Another point is that there are too many Kongming lanterns.

It was like it was raining, crackling and falling non-stop.

It cannot be extinguished at all.

I heard a mess in the Goguryeo camp.

Chen Buyi smiled slightly, turned to Gao Qun and said, "General Gao, the time is here to make contributions, please."

Gao Qun woke up from Ru Meng at this time and suddenly felt a little regretful. He just thought it was for the purpose of cooperating with Shen Buyi's performance, and only brought three thousand people.
Chapter completed!
