Qin Yuyan's injury was actually not serious, it was just an injury on his forehead, and after rubbing the potion and wrapping it in gauze, he waited for the scab to heal slowly, but this incident caused a lot of trauma to Qin Yuyan's psychology.

In the past few days, Zhao Chen will go to the Xue Palace in the morning, and in the afternoon, he will come to the Qin Mansion with Xiangcheng and the two of them to talk to Qin Yuyan, and when it is evening, he will say goodbye and leave the Qin Mansion.

As a result, the wedding date was postponed!

The originally agreed wedding date was at the end of this month, but now, such a thing happened, with Qin Yuyan's current state, it is impossible to get married no matter what.

Therefore, after careful consideration, Zhao Chen had to discuss with Lao Qin and Cheng Yanjin, and postponed his marriage to Qin Yuyan in the future, as for the specific when, it depends on how Qin Yuyan recovers.

After the two classes in the morning, Zhao Chen didn't even return to the teaching building, so he greeted Li Gang and went back to the princess's mansion directly. changed into a clean robe, followed Xiangcheng and the two, and then went to the Qin Mansion.

In the back house of the Qin Mansion, he accompanied Qin Yuyan to talk, but as a result, Lao Qin sent Qin Ming to call him, saying that Grandpa Cheng was here and was waiting in the hall in front.

Since returning from Qinling that day and seeing Cheng Yanjin once, during this time, whether it is Cheng Yanjin or Lao Qin, they seem to have become very busy, Zhao Chen has been in Qin Mansion for almost the past few days, but he rarely meets Lao Qin.

"There you go!" Qin Yuyan still had a circle of gauze wrapped around his head, and when he heard Qin Ming's words, he immediately raised his head, slightly pale on his cheeks. showed a smile, looked at Zhao Chen and said, "I'll just talk to my sister!" ”

"That's it!" Hearing Qin Yuyan's words, Zhao Chen nodded. looked at Xiangcheng on the side, and saw that Xiangcheng also nodded, so he stood up from the stone bench, leaving the two sisters in the back house, and he followed Qin Ming to the hall.

In the hall at this time, Lao Qin and Cheng Yanjin were there, but they were different from the past. The atmosphere in the hall was a little depressing, even if he had always come to the Qin Mansion. Cheng Biting Jin, who likes to babble, was also silent at this time.

"Is something wrong?" Zhao Chen entered the hall, first greeted Lao Qin and Cheng Yanjin, and then. looked at the two people whose faces were obviously wrong in confusion. Asked with a slight frown.

"Sit down!" When Lao Qin heard this, he suddenly took a deep breath with a heavy mood, pointed to the chair opposite, and said to Zhao Chen.

"I haven't had a chance to ask you these days!" When Zhao Chen sat down, Cheng Biting Jin, who had been silent since Zhao Chen entered the door, suddenly looked at Zhao Chen with burning eyes. He asked, "Now let me ask you, what is that thing?" ”

Cheng Biting Jin's words came out. Lao Qin on the side couldn't help but look at Zhao Chen with a look of curiosity.

“… Detonator! When Zhao Chen heard this, he looked at Lao Qin and Cheng Yanjin, who were looking at him with a solemn face, paused slightly, and said in a 1510 voice.

"Detonator?" Hearing Zhao Chen's words, Cheng Yanjin's brows suddenly furrowed slightly, and he turned his head to look at Lao Qin, who was also frowning, before turning around, looking at Zhao Chen and asking, "What is this, it can cause such a big damage?" ”

“… It's a thing that is extracted from saltpeter! When Zhao Chen heard this, he thought about it for a while, and had to start with the formation and power of gunpowder.

There is no way, the thing of gunpowder is a blank in the current Tang Dynasty, and even if it appears, it will not appear until Yuan Tiangang's Dan furnace explodes.

From how saltpeter is refined, to the final formation of gunpowder, and then to the preparation of a powerful thing such as a detonator, Zhao Chen tried to be as concise as possible and explained to Lao Qin and Cheng Yanjin.

With Zhao Chen's explanation, the faces of the two veterans began to turn a little pale, they thought that Zhao Chen used some immortal treasure in Qinling, and that kind of power can only be made by immortal treasures.

However, listening to Zhao Chen's explanation at this moment, I found that this immortal treasure was actually extracted from saltpeter, bit by bit, and then formed after several processes, the shock in my heart was beyond words.

In the era of cold weapons, after all, it is only inseparable from people and horses, and the victory or defeat of a war must ultimately take into account many factors.

However, listening to Zhao Chen's words at this time, the hearts of the two of them were really stormy, they were all veterans of the battlefield, Zhao Chen just said the characteristics of gunpowder, and the two immediately substituted gunpowder into the battlefield.

"What are you going to do with this?" Wu Zi was shocked for a moment, and Lao Qin took a breath, looked at Zhao Chen intently and asked.

When Zhao Chen heard Lao Qin's words, he couldn't help but be slightly stunned, for a while, he didn't react to the meaning of Lao Qin's words, with a puzzled expression on his face, he looked at Lao Qin and asked, "What to deal with?" ”

As soon as Zhao Chen's words came out, Lao Qin suddenly looked at Cheng Yanjin on the side helplessly, with a look of embarrassment, he could see that Zhao Chen really didn't realize the deep meaning contained in this.

"Do you know that in the past few days, Your Majesty and the important ministers of the court have almost all stepped on that place?" Lao Qin couldn't say anything, but Cheng Biting Jin didn't care, looked at Zhao Chen, who was still puzzled, and smacked his teeth hard, and said.

When Zhao Chen heard this, he frowned slightly, and shook his head at Cheng Yanjin.

In the past few days, he has lived a life of three points and one line, the school palace, the princess's mansion and the Qin mansion, and the people he can come into contact with are all far away from the court, so naturally he doesn't know anything about the things in the court.

However, even so, Zhao Chen could also guess that the movement he made this time was bound to cause an uproar in the court.

On that day, for the sake of insurance, he prepared a total of three detonators, plus the land in Guanzhong, which was relatively soft loess layer.

Therefore, when three detonators exploded in the cave at the same time, the kind of damage caused, Zhao Chen could imagine even if he didn't look at it.

And this is not a fixed-point blasting, if he takes the time to arrange it, the destructive power generated by the time will definitely be more shocking than what is seen now.

"Hey!" When Cheng Yanjin saw Zhao Chen shaking his head, he immediately let out a chuckle, this is good, he made such a big move, which shocked the civil and military forces of the Manchu Dynasty, but he was so good that he turned a blind eye.

"Your Majesty cares about this!" Lao Qin frowned, groaned slightly, looked at Zhao Chen and said, "So, you'd better have a proper way to deal with it!" ”

If it was too direct, Lao Qin couldn't say it, but even so, this sentence was enough to explain things.

Zhao Chen's movement this time was too big, so big that it had already made His Majesty the Emperor jealous, one hellfire was enough, and now there was an extra gunpowder detonator, which would be strange if the emperor was not jealous.

“… Got it! Hearing Lao Qin's hint, Zhao Chen suddenly understood, was silent for a while, and then raised his head to look at Lao Qin and Cheng Yanjin, chuckled and said, "The little nephew will handle it properly!" ”

When Lao Qin and Cheng Yanjin heard Zhao Chen's words, they nodded slightly, and then stopped saying anything.

In the final analysis, whether it is the hellfire or the gunpowder detonator that appears now, it is Zhao Chen's thing, and they only give Zhao Chen a little advice, and the rest needs Zhao Chen to make up his own mind.

came out of the hall, and accompanied Qin Yuyan to talk in the back house, and when it was almost evening, he and Xiangcheng left the Qin Mansion together, got into the carriage and went straight to the princess's mansion.

Sitting in the carriage and looking at the palace in the distance through the window, Zhao Chen couldn't help but sigh in his heart.

Although Lao Qin and Cheng Yanjin didn't say it clearly, he heard the meaning of the words, and both hoped that Zhao Chen could hand over the things to the royal family.

This time, the movement he made was too big, which made Li Er, as the emperor, feel a sense of crisis, which was obviously not a good sign.

Although, since Zhao Chen came back from Lingnan, the emperor has protected him everywhere, and this kind of protection is sometimes called connivance, which is not an exaggeration, but no matter what, it was in Li Erjue's before, and he could control Zhao Chen.

Now, Zhao Chen made such a big move, in addition to the hellfire, there is an extra gunpowder detonator, and compared to the hellfire, it is more powerful and more destructive!

Therefore, Li Er naturally had a feeling of uncontrollability towards Zhao Chen, and now although he was silent, he was not in a hurry to summon Zhao Chen into the palace, but it was this silence that made people feel depressed.

The last time there was a steel man, Li Er waited for Zhao Chen to recover, and immediately sent the old eunuch over, with a 'bad' attitude that he should be handed over.

But this time, the gunpowder detonator obviously caused such a big movement, but Li Er seemed to have forgotten and ignored Zhao Chen.

"I'm waiting for me to take the initiative!" Thinking of this, Zhao Chen suddenly sighed, withdrew his gaze from the car window, tapped his fingers lightly on his knees, and whispered.

"How... What's wrong? Hearing Zhao Chen's sudden sigh, Xiangcheng, who had been looking at him beside him, suddenly looked at him nervously, and asked cautiously.

This is a sensitive woman, thoughtful, when Zhao Chen came out of the Qin Mansion just now, she looked preoccupied, and she felt that something was already wrong.

As a result, when they got into the carriage, Zhao Chen kept looking at the direction of the palace through the car window, and his heart was even 'groaning', but now when he heard Zhao Chen's words, he immediately asked nervously.

"It's fine!" When Zhao Chen heard Xiangcheng's cautious question, he turned to look at Xiangcheng, stretched out his hand to hold Xiangcheng's hand, patted the back of Xiangcheng's hand gently, and smiled at Xiangcheng.

When these words fell, Xiangcheng leaned his body, and he fell into Zhao Chen's arms like a cat, and it could be seen that Zhao Chen's words just now had made Xiangcheng scared.

Gently stroking Xiangcheng's jet-black hair like ink jade, feeling the fear of Xiangcheng in his arms, Zhao Chen cast his eyes on the car window, looked at the palace under the sunset in the distance, and sighed softly. (To be continued.) )
