But it's that kind of credit, Pang Yizhu tried his best to take it for himself, and with what he did, now he was only demoted by one level, if he said that there was no one behind him, they would never believe it!

It's just that the people behind him haven't been figured out by them yet, so once Pang Yizhu learns about the existence of firearms, I'm afraid that he and the people behind him can't wait to take this credit to themselves!

Even other bulls, ghosts, snakes, and gods will jump out and muddy the waters!

After all, since the Holy Emperor ascended the throne and succeeded to the throne, he advocated emphasizing literature over military force, and reduced the expenditure of many military departments, which made gunpowder and firearms, which were already very difficult to develop, even worse.

Although in recent years, the Northern Wu Dynasty has invested a lot of money and talents in the development of gunpowder and firearms, but very few have really achieved results.

In addition, this research and development did not cost the people and money, and at this juncture of the Xirong invasion, no matter who came up with such a big killing weapon, they will definitely be able to leave a name in history, and this is a once-in-a-lifetime great achievement!

Maybe you can get the last purple gold token left in the Beiwu Dynasty, adding a way to save your family's life!

At that time, not to mention that Guan Luan's father is just a small seven-rank official, that is, Luo Yukang's father is a dignified secretary of the Ministry of Rites, and people will not hesitate to threaten and lure or persecute something!

Thinking of this, Luo Yukang and Guan Luan felt that the heavy responsibility on their shoulders was really not small, and the danger they were about to face was not small, but even so, they did not have any thoughts of retreating, and their eyes became more and more determined.

"So, Shu Bai, Ah Duan, you each bring some people to be responsible for protecting the safety of the two of them, the scope of this matter is too large, we must ensure their safety, of course, we must also protect this secret recipe." Mu Yuan added on the side.

And with his words, everyone understood the seriousness of this matter, and the expressions on their faces couldn't help but become much more serious.

Ye Zhi was a little indignant, after all, normally he and Ji Shubai should protect Luo Yukang and Guan Luan respectively, but now he was "eliminated", and he was replaced by Shen Duan, who had a better relationship with Mu Yuan, which made him glaring at Mu Yuan.

Hum! Cronyism!

"In the end, it is up to the rest of us to make the final escort for this matter, Ye Zhi, this requires you to go home and ask your father for help.

I think that last time Pang Yizhu intended to steal the credit of the transformation weapon, your father should have heard about it, with his ability, if he can help us continue to investigate, or give us a direction, then it will definitely let us find out the person behind it with half the effort! ”

Hearing his words, Ye Zhi nodded, and the discomfort that had just arisen in his heart dissipated a little, "Okay!" Anyway, as long as I open my mouth, my father will definitely not refuse! ”

"What if it's not the right thing?" Someone asked curiously.

"Then break my dog's legs!" Ye Zhi and Guan Luan said in unison, and then the two of them looked at each other, and laughed at the same time.

It took a moment for the others to react, and they couldn't help but burst out laughing.

“…… Ahem! If you don't have any opinions, then this matter is settled, remember, we must do it in secret, and we must solve it quickly, you know? ”

After a while, Mu Yuan cleared his throat and said very seriously.

Even if everyone gave it up, the appearance of unity made Mu Yuandang understand why Nangong Jue chose to send this secret recipe to Luo Yukang and Guan Luan, just because she knew that these people regarded her as a real brother.

What's more, they are all innocent hearts, so they will only feel honored for their brothers' merits, and they will not be jealous, and even want to take them for themselves......

Thinking of this, Mu Yuan's original thoughts about the people in front of him couldn't help but change a little.

"One more point."

After everyone calmed down, Wen Yan spoke again, drawing everyone's attention to himself.

"What?" Mu Yuan raised his eyebrows slightly in confusion.

Xiaoshuang said that she sent one more back just in case. Wen Yan pointed to the letter, although Nangong Jue did not write his recent situation on the letter, but this sentence is enough to prove that the secret recipe in the hands of Luo Yukang and Guan Luan is not the only one.

"So...... She already knew that someone would rob her of her credit? Mu Yuan reacted quickly, and his brows couldn't help frowning.

And his words made Ji Shubai and the others show a little resentment on their faces, and at the same time, they became more and more determined in their hearts to escort Yu Chengshuang.

"It seems that even if Xiaoshuang is exiled to the border city, there are still people who are not at ease!"

Mu Yuan's face suddenly became very ugly, and Wen Yan nodded, and said with a solemn expression: "Someone is monitoring her every move." ”

Therefore, Nangong Jue's tinkering with the grenade may have been discovered by those behind his back!

"What then?"

"You guys still do what Mu Yuan said just now, and leave the rest to me and Mu Yuan." A trace of coldness flashed in Wen Yan's eyes, and Mu Yuan exchanged glances with him when he heard this, and when he learned that the other party wanted to use the jade pendant that Nangong Jue left him, Mu Yuan hesitated for a moment before nodding.

"Good!" Seeing this, Ji Shubai and the others all nodded in agreement, and they also knew that Wen Yan was taking the most dangerous place on himself and Mu Yuan.

With Wen Yan and Yu Chengshuang's good looks, they felt normal, but as for Mu Yuan, Shen Duan remembered Nangong Jue's somewhat ambiguous attitude towards him, and couldn't help but be a little suspicious in his heart.

Two days later.

Luo Yukang and Guan Luan worked day and night in the military department according to Yu Chengshuang's secret recipe, but something happened in the middle, which almost made them fall short.

Fortunately, in the end, they used the materials stored in the military department to make ten grenades, and then under the escort arrangement of Ji Shubai and Shen Duan, they found the most remote barren mountain on the outskirts of the city, and communicated with the local officials.

On the other side, the battle report from the front finally reached the imperial capital, but the secret recipe for firearms that was supposed to enter the capital together was not taken seriously, and was thrown into the corner along with the box where the grenade samples were placed.

However, Mu Yuan and Wen Yan were a little relieved, after all, at least the secret recipe and grenade were not robbed.

Knowing that Shucheng had been breached, and the border city was surrounded by 300,000 troops of the Xirong tribe, the saint was shocked and furious, but he still had to immediately convene the ministers of the various ministries to start discussing.
