As soon as these words came out, the eyes of several people couldn't help but light up, "Okay! Wonderful! It's a good idea! I'll arrange it!"

As soon as General Gao heard Lian Yi's words, he immediately understood what he meant, they now have a unique advantage, if Lian Yi is in the middle, things will definitely get twice the result with half the effort!

They can disguise themselves as a caravan and use this to trade with Prime Minister Qin, so that they can intercept this batch of goods, and they can also catch him!

If there is a transaction, it will leave traces, so if it can be implemented well this time, it may be able to catch Prime Minister Qin!

However, because the current evidence is still lacking, for the time being, he can only be allowed to go unpunished for a while!

Thinking so, several people began to prepare.

After Lian Yi handed over a letter to Gao Chen, the group set off to return to Yanzhou.

Under Lian Yi's recommendation, the group successfully purchased the last batch of black crystals from the base, and in addition, Lian Yi also drew a road map to the base mine, and everyone stole the only remaining black crystals, and then sent them to the palace.

"Your Majesty, I have a way!" After the two sent Sombra to the palace, they came to meet the emperor.

And at this moment, the emperor is worried about one thing.

That is the death of General Mo!

Although it is already known that General Mo's death has another hidden secret, but so many years have passed, and General Mo's body has long since turned into dry bones.

How can the cause of his death be established now?

For this reason, the emperor had a headache, and he didn't know what to do for a while.

As soon as Du Peng said this, joy immediately appeared in his eyes, "What can I do if I am a real countryman?" ”

Du Heng's eyes flashed, and he said excitedly, "Although General Mo has long since died, the corpse will leave evidence for people!" ”

When the emperor heard Du Heng's words, a wave of doubts rose in his heart, and when he saw Du Heng's confident face, he immediately stopped doubting.

After settling the cause of General Mo's death, the emperor said another thing to worry about.

"There is news from the military prison that the minerals can produce a strange power when burned, and now this batch of black crystals has also been sent to the military prison." The brows of the Internet furrowed. Looking at Lian Yi and Du Heng, "I haven't found out where this black gold can be used yet, I wonder what you two think?" ”

In addition to emitting toxic gases when black crystals are burned, they don't know what else this black gold can do.

However, at present, the state affairs are quite peaceful, and for the time being, there is no need for these black black crystals to fight against the enemy.

But so many black crystals are stored in the palace, but they are idle, which is really a headache.

So the emperor thought that it would be better if he could use these black crystals to do something useful.

Hearing the emperor's words, the two of them couldn't help but fall into deep thought, and for a while, everyone was embarrassed about the usefulness of this black crystal.

Just when everyone was thinking about what to do with this batch of black crystals, Du Heng suddenly raised his head and said excitedly to the two of them: "I have a way!" If the emperor believes me, you can hand over this batch of black gold to me to deal with! ”

When the emperor heard this, he couldn't help but look at her in surprise, could it be that she could be of any use?

Du Heng saw the confusion in the eyes of the two, but he didn't explain too much, just smiled mysteriously at the two of them, "You'll know when the time comes!" ”

Seeing this, the two didn't ask any more, but then Du Heng asked the emperor to order the recruitment of the world's skilled craftsmen to the palace.

In this regard, the two were even more puzzled, but no matter how the two asked, Du Heng did not tell the two of them the reason for the incident.

Seeing that he really couldn't ask anything, the emperor gave up, and secretly ordered to summon a lot of talented people who knew how to make machinery into the palace, and under the guidance and guidance of Du Heng, the first batch of fans forged with black crystal as fuel soon came out!

"Heng'er, this, what is this?"

But I actually saw it. Du Heng. After the power fans were made, they were all dumbfounded. Circling around in front of the power fan, Lian Yi raised his head to look at Du Heng with a confused expression, and then asked.

Du Heng didn't explain to him, but smiled at him and walked towards him, "Don't you know if you look at it?" ”

Under his gaze, he put Black Crystal under the base of the power fan, and then reached out to touch the corner of the power fan, and then everyone saw the power fan spinning rattling.

For a while, everyone at the scene was stunned and their mouths were long, their eyes were about to pop out, their eyes were staring at the power tightly, and the fan didn't blink.

After being silent for a long time, he finally believed that the scene in front of him was real, and slowly walked up.

After confirming that the fan could really be turned, one by one they got closer, and saw that the wind was blowing the hem of their clothes, except for the wind blown by the fan, the rest of the body did not feel the wind, and everyone couldn't help but close their eyes and feel the coolness of the artificial wind.

"I don't know how long it took for everyone to come back to their senses from this shocking scene." Seeing this, Du Heng said to the emperor who was on a high seat not far away: "This is the role of Black Crystal!" ”

The combustion of black gold has a certain power, and this power fan uses this principle to use its combustion as a power assist to make it rotate, thus forming an artificial fan.

When the emperor saw this scene, he was already shocked, and then after hearing Du Heng's explanation, he nodded clearly. He looked at her with joy, "Very good! Very good! Can this black gold be made into other objects? ”

When he saw the power fan, the emperor was extremely excited.

If you can make a power fan with this burning power, can you also use this black crystal to make other power objects?

As long as he thought of this possibility, and the whole world was only in their country, Black Crystal, the emperor's eyes unconsciously shone brightly.

In this regard, Du Heng said that it is not impossible, but further exploration is still needed to know.

And after making the power fan, another thing has progressed.

The emperor ordered General Mo's grave to be dug up so that Du Heng could examine the body, but this act angered someone.

"Is the national teacher Du Heng back?"

Ran Niang, who got the news here, searched all the way back to the capital, and since she was secretly transferred out last time, she has been wandering and hiding all the way.

I wanted to just find a place to live on the land, but I didn't expect them to do this!

She knew that she would not easily trust this royal man!

Du Heng actually deceived her, how could she bear it!

When she heard the news that the emperor actually ordered that her husband's grave should be dug up to whip the corpse, she almost didn't get angry!

"National teacher Du Heng? You say a national teacher! She and the son of Lianyi have already returned! ”

This passer-by in Kyoto heard her ask Du Heng, and immediately told him what he knew, but it has been a long time since the big news of the national teacher's return, and this person's news is really backward enough.

After hearing this, a trace of resentment appeared in Ran Niang's eyes.

The person she asked couldn't help but be taken aback.

And here, after knowing that the national teacher Du Heng and Lian Yi had returned to the capital, the only luck in Ran Niang's heart was gone!

There was only anger left in his eyes, his hands clenched his fists angrily, and he slammed back into a medicinal herb shop on the corner, "Boss! Give me a husband and a pair of arsenic! ”

The anger on Ran Niang's face had been put away, but her eyes had not diminished at all, and in her resentment, the shopkeeper of the pharmacy unconsciously shrank, her hands trembled, and she asked nervously, "I don't know what this arsenic is for?" ”

The shopkeeper had horror in his eyes, and he didn't know whether to give her this medicine or not, if she sold it like this, it would not be a trivial matter to harm people!

Therefore, it is better to ask clearly, not to mention Ran Niang's appearance, it is not normal at first glance!

And when Ran Niang heard this, she couldn't help but come back to her senses, her heart sank slightly, she endured the anger in her heart, and impatiently explained to the shopkeeper, "It doesn't work, it's just a mouse who poisons the family!" ”

After hearing this, the shopkeeper calmed down, but her expression just now was too scary!

Then he turned around and went to the medicinal herb cabinet behind him, and grabbed a pair of arsenic for her, but when he handed it to her, he was still a little uneasy, "Remember not to break the law!" ”

Their country does not regulate skin arsenic, but if someone is killed because of this, their pharmacy is also responsible!

That's why he's so cautious.

And Ran Niang looked at him with a nervous look, her eyes dimmed, she didn't want to hurt anyone, but wasn't this forced by them?

She trusted them so much and had hope for them, but what!

How did they respond to themselves? He actually wanted to dig up the former husband who had already been buried in the ground and whipped the corpse! Is this still a human thing?

Realizing that her emotions began to become excited again, Ran Niang hurriedly forced herself not to think about it, and then replied perfunctorily, I love you and paid and left the pharmacy.

It's just that what she didn't know was that as soon as she left the pharmacy, the shopkeeper of the pharmacy walked out, looking at her departing back, a trace of worry appeared in her eyes, and then beckoned to the little guy standing in the corner, signaling him to come along, "Hurry up and tell the national teacher!" ”

After sending the little guy out, the shopkeeper can be regarded as relieved.

Du Heng had already guessed that Ran Niang would settle accounts with them in the capital, so the pharmacies under his command were all staring at it, and if Ran Niang appeared, she would get the news immediately.

However, these are all things that Ran Niang didn't expect, her heart was looking for Du Heng to take revenge on them, and she didn't think that her whereabouts had been monitored by them from the moment she entered the capital.
