When Zhao Kun heard the explosion from the minefield, he was not surprised, but his face became heavier.

He knew that this might be the advance team sent by Yin and Yang Palace to inquire about the road conditions ahead so as to avoid any ambush.

Obviously, this strategy was successful.

The roar shocked the army of Yin and Yang Palace in the distance.

Don't know what happened.

At this moment, a knight riding a war horse, obviously looking like a female general, rode his horse to a general wearing a cloak and armor and whispered: "Your Highness, a roar of thunder came from the front, and then the ground suddenly exploded, and the team heading to explore the way also suffered heavy losses. Now less than half of the people are back, and they are all wounded."

Hearing this, the general who was wearing a cloak frowned, then lowered his cloak, revealing a heroic face.

This person is the seventh princess of the Great Qin who disappeared in Xianyang, Ying Yinman.

But after hearing the report, Ying Yinman looked up at the direction where the rumbling sound came, with a solemn expression on his face.

What happened when thunder roared and the ground suddenly exploded?

Is there a thunderstorm tonight?

But just now, the sky was clear and I didn’t see any lightning falling from the sky. How could such a strange thing happen?

Ying Yinman was confused.

This phenomenon seemed to be beyond her imagination.

At this moment, Ye Yuebai, who was standing beside him, suddenly spoke: "Princess Yinman, I once heard of the Qin army's weapon called musket!"

"Will this movement be caused by the secret device created by the Academy of Sciences? For example, burying it underground, once someone passes by, it will cause an explosion..."

"The secret tool created by the Academy of Sciences?"

Ying Yinman frowned even higher: "Why haven't I heard of this kind of secret weapon before?"

She had a new understanding of the Academy of Sciences in her heart and no longer thought it was the yamen that Zhao Kun had tortured.

After thinking about it, Ying Yinman asked, "What Miss Yiyeyuebai said, there must be that kind of thing on this path. What should we do?"

"You can't detect it with people or bypass this mountain, it will take nearly a day."

Ye Yuebai said, comforting: "Princess Yinman, don't worry, I have my own way."

After she finished speaking, she shouted to the archers behind her: "All archers leave the line, take out an arrow and tie a small stone."

Hearing this, the archers behind him dispersed one after another, found a small stone nearby, and tied it to the arrow.

Seeing this, Ye Yuebai showed a satisfied smile on his face: "Princess Yinman, let's go."

"Um?"

Ying Yinman saw the archers tied stones to the arrows, and his eyes suddenly lit up.

I think Ye Yuebai wanted to use these arrows to check the kind of explosions along the way.

Ying Yinman also admired Ye Yuebai.

This woman is not only beautiful but also so wise, which is rare.

When he looked at Ye Yuebai in his eyes, he actually showed a hint of favor.

But Ye Yuebai did not look at her at this moment, but waved his hand to order the archer to come forward.

As the army arrived at the place where the explosion had just made, there were large pits that could be buried in one person on the ground, which surprised everyone.

Could this ambush Qin army have the means to reach the sky?

.........

Just when the Yin-Yang Palace army appeared in the minefield.

On the hillside not far away, Zhao Kun held a telescope in his hand and looked at it, his face looking a little ugly.

There, Ye Yuebai was commanding the archer and shooting arrows continuously towards the minefield in front.

The moment the arrow fell, bursts of explosions came, and the entire earth was shocked.

When the Yin-Yang Palace army heard the explosion, they hurriedly covered their ears. Some people who were slow to see blood flowed out of their ears.

When Ying Yinman saw this scene, her eyes also showed shock.

When I thought that if I had not discovered the minefield in advance, I had passed by here recklessly, I might have been in a different place now.

Looking at the big holes that exploded and were indented in front of you, you can imagine how terrifying the power of this thing is.

If you throw it into the army and explode again, you can imagine that the army behind you will be injured more than half in an instant.

Ye Yuebai's face looked even worse.

Obviously, she underestimated the Qin army's methods.

Looking at the current situation, we can know that this is definitely a new secret tool from the Academy of Sciences.

Bury it underneath, once a person steps over, it will affect the mechanism below, thereby bursting out a force and blowing the person to death.

Such methods are really heartbreaking.

Looking into the distance, there is a long road.

Ye Yuebai couldn't help but guess in his heart that these Qin troops would have arranged that thing on this road, right?

If so, their next journey will become extremely difficult.

If it is even necessary, you can only take a detour.

At this moment, Ying Yinman suddenly asked: "Miss Yeyuebai, how many things do you think the Qin army will lay down on this road?"

"I don't know either."

Ye Yuebai shook his head, and there was no answer in his heart. Who knows how much Qin army released?

However, after thinking for a while, she solemnly said: "The Qin army appears here, and we think our traces have been exposed. I think it's better to test for a while. If there is still, we will go around and cannot take risks."

"Um."

Ying Yinman uttered softly, and she had the same plan in her mind.

I have to say that the appearance of Qin Jun here made her a little at a loss.

It was obvious that their operation was very secretive, but in the end it was discovered, which showed that the Qin army's intelligence spy was very good.

And she could never imagine any Qin army organization except Zhao Kun’s slogan.

"Miss Yeyuebai, you said, will Zhao Kun lead the Qin army that ambushed us this time?"

Ying Yinman gave his own guess.

Ye Yuebai was stunned for a moment and said in surprise: "No, he is the prince, how could he take risks with his own life?"

"Before this, I had never heard of the war in Daqin that had such a means, so I guessed that Zhao Kun was here in person."

Ying Yinman sneered: "And Zhao Kun is not a person who follows the rules. If he knew that our army was a private army of Yin and Yang Palace, he might be very interested!"

"this...."

Ye Yuebai hesitated for a moment, his expression gradually became solemn, and then he asked, "Then... how do we deal with it next?"

"Um....."

Ying Yinman suddenly fell into deep thought when she heard Ye Yuebai's words.

Before she knew it, her nose sniffed, and the smell of gunpowder filled the air aroused her shock.

So he turned his head and asked, "Miss Yeyuebai, do you think that something has a strong smell of sulfur?"

"Sulphur smell?"

Ye Yue's eyes lit up, his nose moved slightly, feeling the scent that spread, and was a little surprised: "It does have a very heavy smell of sulfur."

"Can this explosion be made of sulfur?"

Thinking of this, Ye Yuebai pondered: "This thing should have some other ingredients."

"If we can tell the ingredients, we should be able to make them."

Ying Yinman suggested on the side that she smelled more than one smell.

As he finished speaking, Ye Yuebai's face showed a look of surprise.

Thinking of the amazing scene just now, if Yin and Yang Palace could also create such a secret weapon, the combat power of the Yin and Yang Palace army would soar.

"Haha, Zhao Kun may not have thought we had such ability."

"Once we know how this thing explodes, we can throw it to break through the city gate."

"I believe that by then, we don't need to send a large army to attack the city. If we bombard them all the way, Zhao Kun will be unable to fly."

When Ying Yinman heard this, she was happy. She thought it was unfavorable to go to the army, but she didn't expect that she would have such a discovery.

But then, she discovered another problem, they could not detonate all obstacles.

Otherwise there would be nothing to do research.

"Miss Yeyuebai, don't rush to let someone clear the obstacles, let's investigate and see what the explosive looks like."
