The door of the study room was closed, and Xuanyuan Liuyun sat on the chair, waiting for Chen Wan to tell him how the sky thunder was obtained.

Chen Wan sat opposite him and looked at him and said, "I made this thunder. I used gunpowder to figure it out by myself based on the principle of firecrackers, in order to save Ziling.

But if I declare to the public that I did it, it will definitely cause a lot of trouble, so I said that to the people of the Northern Region.”

firecracker?

Yes, the firecrackers will explode, and the sky thunder will explode.

People often get hurt by firecrackers when they are playing with firecrackers.

During the Chinese New Year, every household was able to use the firecrackers, but no one had ever thought about using the gunpowder used for firecrackers to make such a powerful weapon. Mrs. Song thought of it in order to save her son.

Xuanyuan Liuyun said: "Mrs. Song can make such a powerful thunder based on the principle of firecrackers. It is really admirable.

However, the thunder is based on the principle of firecrackers, and the matter made with gunpowder must not be disclosed."

If people from the Northern Region and other countries know about it, it will probably cause more disasters to the creatures.

Chen Wan said: "Now no one knows this except the three of us."

Upon hearing this, Xuanyuan Liuyun nodded with confidence and said, "We must report to the emperor immediately if the Tianlei and the surrender of the people of the Northern Region to retreat and surrender."

Song Heng frowned and said, "Can the emperor announce to the outside world that he secretly developed this thunder?"

He didn't want anyone to doubt Wan'er's head.

Xuanyuan Liuyun thought for a while and said, "I will send a secret letter to the emperor, but Mrs. Song would better attach the method of making this thunder."

The emperor attaches great importance to Mrs. Song, and he should not want her to cause trouble because of this thunder.

Chen Wan hesitated for a moment, nodded and said, "Yes."

Since Xuanyuan has the ancestral teachings of not invading other countries, there is no problem in giving the production method to the emperor.

Chen Wan immediately wrote down the method of making Tianlei and the precautions during production.

Xuanyuan Liuyun picked up a pen and wrote a letter to the emperor, writing about the matters of Tianlei and the Northern Region.

After writing, the method of making Chen Wan's writing was put into the envelope, sealed with a fire varnish, and sent a team of confidants to the imperial city immediately and handed it to the emperor.

After leaving the study, Chen Wan also called all the people who came to the border with her and told them that the emperor knew that she came to the border.

When the emperor knew that she was coming to the border, he entrusted her the secret of the thunder to bring the border to see if he could use the thunder to shock the Northern Region to rescue Ziling.

Why did the emperor deliver such an important thing to her? It was because the emperor was afraid that the iron cavalry camp would have a fine work of the barbarians, so he stole the thunder and then delivered it to her to bring the border.

She said this that, the soldiers, Qiuju and Huier didn't doubt anything, and believed it. Although Zhao He still felt something was wrong, he didn't think about it anymore.

After Song Ziling was taken back by Yelu Ye, he changed his residence. Yelu Ye changed him to a very good tent and told someone to watch him well and serve him with delicious food and drink.

After meeting his parents, Song Ziling missed his parents more and more, and wanted to go home more and more.

But he believed that he would be able to go home soon.

He was not saddened by his parents' cruelty today, because he knew very well that if his parents were not cruel, the barbarian would unscrupulously threaten them with him and ask them more excessive conditions.

Only when his parents act cruelly, the more smoothly he can let the barbarian let him go back.

Seven days later, a secret letter from the northern border was delivered to Xuanyuan Yu.

The next morning, Xuanyuan Yu announced to all civil and military officials that the thunder he secretly created successfully shocked the barbarians of the Northern Region.

The barbarian not only retreated his troops, but he might also surrender to Dongchen and surrender to him in a short while.

The civil and military officials in the court were both surprised and happy, and knelt down and shouted: "My emperor is wise and divine, and God blesses Dongchen."
