It's just that her somewhat ridiculous tone made Zhong Shi blush a little, and then he briefly talked about what happened to the other family members recently.

Although he had just said that everything was fine at home, in fact, there were still some things that happened on Nangong Jing's side that could not be said to Nangong Jue, after all, those things are still a mystery, and no one knows why, so naturally they can't only increase the other party's worries.

And Nangong Jue's attention was on the letter with Wen Yan's recent situation in his arms, and naturally he didn't notice Zhong Shi's strangeness when he narrated, "By the way, apart from these things, did Ah Jing ask you to bring me anything else?" ”

She took out a small bottle from her arms and signaled, you must know that the Qingxin Pill she was carrying was almost finished, and it was time to replenish the stock!

“…… No. Zhong Shi shook her head, and the blank look made Nangong Jue sigh helplessly, and then she waved her hand to let him leave.

That made Zhong Shi feel like he was going to have the rest of his life, and he immediately turned around and left quickly.

In fact, he knew what Nangong Jue wanted, but unfortunately, some changes had happened at home, not to mention the Qingxin Pill, there was no other medicine!

And after he left, Nangong Jue took out the letter again, and there was a hot feeling on her face, and the whole person opened it a little nervously, but found that it was actually another envelope inside, and the words on it made her eyes widen immediately.

"Jue'er personally opened".

The simple four words made the corners of Nangong Jue's mouth can't help but rise, and the place where her fingers touched seemed to have an electric current flowing through, numbing to the bottom of her heart......

It's just that when she opened it, the smile on her face immediately froze.

……

Five days later.

"Bang!"

A loud bang sounded in the barren mountain almost ten miles away from the border city, and Nangong Jue and Pu Ce jumped on a small hill after the sound to watch from afar, only to see that the place where they had just thrown the "grenade" had now been blown out of a big hole, although it was smaller than what Nangong Jue had made at the city wall before, but its power had already achieved their purpose.

"It worked!"

Pu Ce said with some excitement, you must know that they have all received the news of the impending attack of the Xirong clan, but there has been no progress in the transformation of firearms, and Nangong Jue has devoted himself to the development and transformation of firearms after completely "filling" the big hole two days ago.

During this time, she tinkered with some simple firearms, but the recoil was very strong, and if it was not protected by hard armor, it was easy to cause damage to the shoulder.

And these are all things that take time to slowly explore and improve.

Fortunately, she had already made a half-finished "grenade" before, and Park Cha had been improving it with people during this time, and she put forward several key points after she joined, and by this morning, they had finally made ten "grenades".

Just in case there was another mistake made by Nangong Jue before, they came to this barren mountain with these ten grenades to try their power.

They were pleasantly surprised that three of them were randomly drawn, and that each grenade was as powerful as they expected, but unfortunately, the ten grenades alone had already consumed all the materials they had stored in the border city, so if they wanted to make them, they would have to ship them from elsewhere.

But now the result of the experiment is that they have achieved the expected goal of making grenades, and they have achieved a phased victory!

As long as they record the raw materials and process of production, they submit them to the imperial court, and then the imperial court will conduct experiments to obtain the best secret recipe for gunpowder ratio and the best materials for making firearms.

Once the ratio they recorded really allowed the imperial court to make new firearms, then there would naturally be a steady stream of grenades sent to the front line in the future, and with these divine firearms, they would naturally be invincible on the battlefield in the future!

But at the same time, they also have to protect the secret recipe of their firearms, otherwise, it will be a double-edged sword, which can both give them victory and inflict heavy casualties!

"Report - the Xijon tribe is coming! The Bundle City is broken! The Spirit Wolf King led 50,000 elite soldiers to the city soon! ”

Just when Pu Ce was still thinking about how to escort the secret recipe back to the imperial capital, the soldier's voice came, making him and Nangong Jue exchange glances immediately.

"You go to fight, I'll write down the secret recipe, and by the way, take two and send them back to the imperial capital." Nangong Jue immediately understood Pu Ce's plan, and her words also reassured the other party a little, and then they split into two ways.

Fortunately, they had been prepared for the attack of the Xijon tribe, and through the secret passage, even if Pu Ce rushed back from outside the city, it was just in time for the Xijon soldiers to arrive under the city.

The vanguard of 50,000 soldiers and horses, densely packed with people outside the city, made Park Ce sigh in his heart, and then the scouts discharged by their Zhenguo army came to report that the Xirong tribe attacked this time, and dispatched a full 300,000 soldiers!

And the national army defending the town in their border city is only 50,000 when it is full, and even if the people in the entire border city are counted, it is only about 120,000......

What's more, the Xijon clan is the most brave and warlike spirit wolf king of the Xirong clan!

This made the guards on the city wall very nervous, as if facing a great enemy.

"General Park, this king is just here to talk to you this time, if you surrender at this time and surrender to our Xirong clan, this king can guarantee that he will never kill half a civilian after entering the city!

But if you resist, then don't blame the king, and lead your troops to slaughter you! ”

Hearing the words of the Spirit Wolf King, Park Ce clenched the big knife in his hand, but unfortunately now was not the time for them to show the grenade as a hole card.

After all, they only have seven grenades left, and after deducting the two that Nangong Jue wants to send back to the imperial capital, there are only five left, and they have not yet undergone many formal tests.

If it is taken out and unveiled now, if all of them are successfully exploded, it is fine, but once there is something missing, it will be subtracted by the people of the Xijon tribe, then the secret recipe of gunpowder ratio will be exposed!

What's more, even if the remaining five grenades all explode successfully, although they can severely frustrate the opponent's spirit, they will not cause heavy damage to the opponent, so that they can retreat like this......

"Didn't the Spirit Wolf King rinse his mouth before going out today? This breath is really not ordinary! Nangong Jue jumped up from the city to the city wall and heard the other party's last words, and couldn't help but reply angrily.

How dare you say that you want to slaughter them?
