Hulu Baqi was so at ease that he fell asleep all of a sudden.

But Song Tianming was still thinking about what the current situation was, and what to use to trigger resonance.

Zheng Sheng was on the night, and saw that Song Tianming's tent was still lit, he walked in.

"Mr. Song, I still haven't fallen asleep at night. I'll have to march in a hurry tomorrow morning."

Zheng Sheng said, looking at Song Tianming, but Song Tianming was looking at the sand table.

It is marked with mountains, rivers, place and road names, but it is not marked with vegetation such as forests.

This was nothing in ancient times. If it was a modern war, vegetation was still very important. It could be used as a bunker or a weapon.

"General Zheng, we headed back to Yunpo, but there was some place where bamboo grew."

Song Tianming looked at it for a long time but couldn't tell anything, so he could only ask questions.

"bamboo?"

"There is less than fifty miles to go back to Yunpo here, but there is a bamboo forest. I just don't know what the sir wants for bamboo."

Zheng Sheng thought for a while before answering.

In Zheng Sheng's eyes, the function of bamboo is nothing more than to build bows and arrows.

But the creation of bows and arrows is not a matter of a day or a night, and it will take at least one year to create a good bow.

Moreover, bows and arrows cannot make Huiyunpo collapse.

"It's easy to deal with bamboo. When you go there tomorrow, cut down a hundred bamboos, which you need to use."

Song Tianming finally smiled on his face.

Although the amplifier made in this way is not very effective, as long as the frequency is lowered, it is still very likely to resonate with Huiyunpo.

As long as there is a resonance, not to mention the collapse of the Huiyunpo, it is not a problem that the entire ground collapses.

"Sir, I said to me first, and I am also curious about how to collapse back to Yunpo."

Zheng Sheng was idle and wanted to learn a few more tricks from Song Tianming.

Nowadays, no one knows Mr. Song’s ability.

If you can learn a move and a half, there are many benefits.

Seeing that Zheng Sheng was so studious, Song Tianming talked to him.

"Everything in the world is actually moving, but it's just vibration. When the vibrations in the outside world are the same frequency as the vibrations of objects, it will cause collapse or even explosions."

Song Tianming explained briefly, and looked at Zheng Sheng who was confused, and it was obvious that he didn't understand.

After all, Zheng Sheng was born in the army and was good at killing people. He didn't understand such things if he wanted to break his head.

And this is an issue beyond the scope for this era.

"Sir is sir. I can't even understand what I said."

"But as long as you are sure, don't let that guy Hulubaqi succeed."

Zheng Sheng waved his hand and said freely.

After seeing Hulu Baqi's embarrassing appearance, Zheng Sheng wanted to read it again.

This is a very stalemate.

"That's natural, don't worry, General."

After saying that, Zheng Sheng left.

After designing the drawings of the loudspeaker, Song Tianming fell asleep.

Early the next morning, the army set off, leaving a hundred elite soldiers to take care of the horses and wait for the imperial court to send people to accept them.

When passing by the gourd mouth of the Hexi Corridor, the smell of blood was soaring, and blood dried up on the ground to form blood-colored bands.

"well…"

Hulubaqi sighed, "The good man of the barbarians died like this."

"I'm sorry, tribesmen."

He murmured, his eyes gradually becoming clearer.

Because of the war horses given by the barbarians, the entire mission is now equipped with horses, so it only took one hour to go to the bamboo forest fifty miles away.

"Your Highness, stay here for an hour, and I want General Zheng Sheng to get something."

Song Tianming and King Cheng said.

Although King Cheng didn't understand why, he thought it would be a useful thing, so he agreed.

"General Zheng, please let me cut bamboo."

Song Tianming lifted the curtain and walked down. Zheng Sheng gave the horse order and said, "One hundred people went to the bamboo forest to cut down bamboo, the bigger the better!"

After Zheng Sheng gave the order, Song Tianming took out a drawing and called a group of commanders.

"When the bamboo is cut back later, you will divide it into pieces one foot long. A piece of intact bamboo is equipped with three pieces to break it into pieces, and then inlaid it."

Song Tianming just ran the drawings and explained to the crowd of thousands of men. One of the thousands of men who had worked as a carpenter patted his chest and said.

"Don't worry, Mr. Song, this matter is no problem!"

Seeing this, Song Tianming immediately asked, "Can you make this thing?"

"A villain has been a carpenter for several years, so such simple splicing is naturally no problem."

"I just don't know how many sir will do."

The commander of thousands of men, Wang Kun, looked honest.

“Make a thousand!”

"We only need to find dozens of people in our army who understand this trick, and there is no need to be too many."

Song Tianming made a rough estimate.

One thousand loudspeakers are placed on Huiyun slope, and only a part of them needs to be shaken down. At that time, a chain reaction will occur and the entire Huiyun slope will collapse.

“This is simple.”

Wang Kun patted his chest and was very confident.

"Very good, then I'll bother Wang Qianfu."

As soon as Song Tianming finished speaking, a hundred bamboos were chopped back, which showed how fast it was.

Immediately afterwards, the entire army began to make materials and proceed in full swing.

Hulu Baqi walked over and walked around, unable to believe it.

"Just this thing can shake Huiyunpo, I, Hulu Baqi, call Qi Baluhu!"

Looking at the drawing, Hulu Baqi muttered, but Tang Yue looked carefully.

Before the continuous launch of crossbow arrows came out, who would have thought that crossbow arrows could still be continuously fired?

Before the crossbow bed came out, who would have thought that there would be such a great lethality?

And these were all thought out by Song Tianming.

What new weapons will appear this time when targeting Huiyunpo?

"Prince, Song Tianming is famous after all, and this is life-related. I think it should be something not simple."

Seeing that the Daqian army was in full swing to make a loudspeaker, Tang Yue began to think about it.

After hearing what Tang Yue said, Hu Lubaqi frowned.

It seems that there is really a slight possibility.

Just as Hulu Baqi was thinking, the first loudspeaker was ready.

"General! The first loudspeaker is ready!"

Wang Kun presented a hollow object with a small upper and a large lower lower.

"Is this a loudspeaker?"

"Come on Mr. Song quickly."

Zheng Sheng took this thing and looked back and forth.

When Song Tianming heard that the first loudspeaker was ready, he rushed immediately.

"Sir, how should this loudspeaker be used."

Zheng Sheng asked.

"It's very simple, it just needs to be like this."

Song Tianming took the loudspeaker and shouted directly.

"Your Highness Cheng King!"

The sound of echoes circling in the loudspeaker and then emanates, the sound is so loud that it is a bit unbelievable!

"How come Song Tianming's voice is so loud today..."

Hulu Baqi muttered and left after a sound.

Zheng Sheng was shocked when he saw the power of the amplifier. The original sound of the pussy was more than twice as loud!
Chapter completed!
