When Zhao Ying looked over with his burning and serious eyes, Li Beifeng knew that he could not hide it anymore.

For others, perhaps it was just a trick, but for the eldest princess Zhao Ying, no one knew what that meant better than her.

That existence that can easily destroy thousands of troops, even more terrifying and powerful than the great masters of the times.

As she saw with her own eyes, the valley collapsed, covering up countless masters and soldiers!

Who are you?

Either die or be injured!

She knew very well that it must have been made by Li Beifeng.

But, how did he do it?

How could he have such a terrifying influence on the remote control several miles away?

He actually has such ability?

Li Beifeng is very unfamiliar in her eyes!

Under Zhao Ying's burning eyes, Li Beifeng sighed lightly and said, "That's called gunpowder!"

"gunpowder?"

When Zhao Ying heard the name, she frowned slightly, and her eyes showed a hint of confusion: "What is gunpowder?"

"How do you explain it to you..."

Li Beifeng thought about it for a while and thought about the words: "Have you seen fireworks and firecrackers?"

"Fireworks?"

Zhao Ying was stunned, as if she realized something: "You mean..."

"That's right!"

Zhao Ying is very smart. Li Beifeng only needs to remind her to react.

"Just think that is a enhanced version of firecrackers!"

"A enhanced version of firecrackers?"

Zhao Ying felt thoughtful and frowned even deeper.

How could that inconspicuous little firecracker be so powerful?

Looking back on the power that ruins the world, is it really caused by a small firecracker?

Even if it is an enhanced version, how can it be so powerful?

She stared at Li Beifeng with a little suspicion, wondering whether Li Beifeng was still lying to her.

"I really didn't lie to you!"

Li Beifeng shook his head and said sincerely: "Ordinary fireworks and firecrackers are limited in power, but if enough fireworks and firecrackers are gathered together, they can produce qualitative changes... As long as they are well controlled, they can create a destructive power!"

His words are naturally half true and half false!

Gunpowder is indeed a barely enhanced version of fireworks and firecrackers, but the quantitative change that is mentioned later produces qualitative change, which is pure nonsense.

How could real gunpowder be that simple?

Both the raw materials and the formula ratio are very particular. Even though Li Beifeng knew the principle of gunpowder, he was only developed after countless experiments.

However, although it was nonsense, it was enough to fool the eldest princess.

Zhao Ying stared at Li Beifeng's face and saw that he did not look like he was lying.

An incredible look appeared on his cold face: "Can you gather enough fireworks and firecrackers together really have such power?"

"It should be possible..." Li Beifeng said vaguely.

Zhao Ying felt thoughtful, her eyes were slightly condensed, but her heart was particularly shocked.

She witnessed the valley collapse with her own eyes, which was even more terrifying than the Grand Master.

If such a powerful thing could be used on the battlefield... Zhao Ying shuddered as if he realized something!

This is a big killer!

With such power, even thousands of troops may not be able to stop it?!

In an instant, Zhao Ying's heart suddenly jumped, and even his breathing was a little rapid.

But soon, she suddenly realized it again.

wrong!

"Are you lying to me?!"

Zhao Ying's eyes suddenly became cold and he stared at him: "How could it be so simple?"

If it were so simple, why were fireworks and firecrackers not banned by the court? Why hasn't the news of such powerful things been heard from the people so far?

Something is wrong!

Zhao Ying suddenly realized that there was something wrong with Li Beifeng's speech.

"Of course it won't be that simple!"

Seeing that she reacted so quickly, Li Beifeng sighed: "There are many key small details that are beyond the reach of everyone!"

Details are the key!

Zhao Ying stared at him suddenly, his eyes gradually changed: "Is this what you created?"

"That's right."

Li Beifeng vaguely said: "I also learned from the experience of my ancestors!"

"Who is the ancestor?"

"An old gentleman named Sun has passed away..."

Li Beifeng shook his head, and saw that Zhao Ying seemed to want to ask something, and sighed softly: "Do you want to ask, can this gunpowder be used on the battlefield?"

Zhao Ying was silent and nodded after a while.

"able!"

Li Beifeng gave a positive answer.

"The power of a gunpowder can produce is comparable to that of a top-notch master..."

"If it reaches the battlefield, it can easily destroy any army. Any tactics and any elite will be vulnerable in front of it! It can easily change the end of the war..."

Li Beifeng's eyes were calm and he looked at Zhao Ying quietly: "The Dazhao Iron Cavalry is famous all over the world, which makes countless people frightened. But in front of it, it is still vulnerable. No matter how strong the iron armored war horse is, it cannot stop its power..."

Zhao Ying's beautiful eyes were particularly shocking!

She stared at Li Beifeng with a rapid breathing, her cold face full of shock!

She was famous all over the world and the Iron Cavalry of the Dazhao who was founded by the country was not the opponent of this gunpowder?

Vulnerable?

She subconsciously wanted to refute, but when she remembered the power of destructive movement and stillness that had seen with her own eyes, she became silent again!

What he said is indeed correct!

That power is too terrifying and incredible!

If she really uses it on the battlefield, how likely will she win?!

"So, is this your trump card of Northern Qi?"

Zhao Ying stared at him and spoke in a deep voice.

Li Beifeng nodded, but shook his head again.

Zhao Ying was confused.

"It cannot be regarded as the trump card of Northern Qi. No one knows about this gunpowder except me today!"

Li Beifeng said calmly: "No one will know about it!"

Zhao Ying was stunned and looked at him in a little incredible way.

He held such a "divine object" in his hand and never thought about another purpose?

"It does not belong to this era. If it spreads out, the consequences will be unimaginable..."

Just imagine, once gunpowder is passed down through the world, it will inevitably change the current situation, war will surely break out again, and the world will inevitably be in chaos.

Li Beifeng cannot afford the consequences he will face at that time!

Therefore, he never thought of using gunpowder on a large scale.

"I will definitely not use it unless I have to..."

Speaking of this, Li Beifeng looked at Zhao Ying quietly: "I know what you are thinking. Its existence can easily change the current pattern between you and me. So, I will not hand it over to you. However, I can assure you a little..."

"If you and our countries fight in the future, under the premise of non-essentiality, I, Northern Qi, promised not to use gunpowder to the battlefield first..."
