Zheng Ji's reaction made Du Fengju a little puzzled.

Because of the two identities, he has seen Zheng Ji a lot. Whether it is teasing Du Fengju for fun, or respecting and being close to Mr. Du Duan, most of her beautiful face is calm and calm.

It's rare to have such a moment when the gaffe is exposed.

What's going on? He didn't say anything earth-shattering, did he?

He was about to explain, but he heard Zheng Ji hurriedly ask, "Mr. Du, what are you talking about...... Can you elaborate on that?"

It turns out that His Royal Highness Changding cares so much about the bed crossbow?

"Back to Your Highness, I once listened to my righteousness...... My elders once thought that if there was a weapon that could be combined with multiple bows and arrows, it would be much easier. All I've been thinking about these days is how to develop what he calls a weapon."

Speaking of which, he explained a little.

"Your Highness, if the stolen weapons of the Weiwei Temple are really hidden in the Wuge Treasury, and I happen to enter at this time, then I will definitely be caught in it. I've been thinking about how to solve this problem, and finding the lost weapon in the Martial Pavilion Vault is a solution. But there's a more radical way."

"What if I could develop a better and newer weapon than the one stolen from the Guardian Temple?" He said with a smile.

After this incident, everyone thought that finding the lost weapon of the Weiwei Temple was the solution, but he preferred to do the opposite.

Research new weapons and replace them.

This solution is much easier than finding weapon blueprints in the vast arsenal.

The most important thing is that this new weapon is not a castle in the air, but can be manufactured.

When he was still young, his father-in-law once conceived such a weapon, but unfortunately he never had the conditions to do it.

He is now in Jingzhao, in Wuge, and he happened to encounter the matter of Weiwei Temple, although this is a crisis, but for him, it is a timely meeting.

Why didn't he develop it?

For this new weapon, it was worth it to stay up and sleep.

Not only for himself, but also for his father-in-law, and ...... For the sake of the country.

Once the bed crossbow mentioned by this father-in-law can be successfully developed, it will definitely be used in the army, which can deter foreign enemies and strengthen the morale of the army, which is a great good thing for the dynasty.

Zheng Jiqiang suppressed the turmoil in his heart and continued to ask, "This bed crossbow ...... Did Mr. Du's elders come up with it? Can you elaborate on that?"

Although Feng Ju said it very quickly just now, she heard it very clearly, and the first thing he said was the word "righteousness".

Presumably, Feng Ju wants to talk about his father-in-law, that is, Master Lu.

Could it be that the bed crossbow was originally conceived by Master Lu?

Because it was a bed crossbow, she naturally thought of Xue Bed Crossbow, who later shined in the army.

The Xue bed crossbow is also a multi-bow burst, and it also has a long range and accurate target, which has many similarities with what Feng Ju is now described.

What is the relationship between the two?

The Xue bed crossbow was developed by the Xue family of Empress Xue, and it only appeared nine years after Yongning, and it will take several years for it to appear, but now......

Unfortunately, she didn't know much about the Xue Bed Crossbow, so she couldn't tell the difference.

There were so many things in her head at once, they were all tangled, and they were almost messy.

Suddenly, a possibility popped into her mind.

Could it be that Xue Bed's crossbow really has something to do with Master Lu?

But at this time, Xue Bed's crossbow had not yet appeared, and she had never heard Feng Ju mention the bed crossbow in her previous life, so she couldn't verify it.

Since Feng Ju had already mentioned the bed crossbow, it came out a few years earlier than the Xue bed crossbow, so ...... She will definitely help Feng Ju develop this bed crossbow!

Feng Ju is right, in order to completely solve the problem of Weiwei Temple, another method must be used!

She gradually had an idea in her mind, and then said, "Mr. Du, if you need to develop a bed crossbow, there are some in the main hall

People can help. If you don't dislike it, would you like to move to the martial arts arena in the main palace?"

"......" Du Fengju knew that he should refuse, after all, the development of new weapons involved too many people.

It's just that he looked at Zheng Jifeng's eyes, and the ghost couldn't say anything to refuse.

The other party's eyes were so sincere and trusting, as if he had seen him develop a new weapon.

However, he thought day and night that this bed crossbow had not yet been developed.

"Mr. Du, to be honest, there are a group of gentlemen in the palace mansion, perhaps, they can help Mr. Du."

The gentlemen invited back by Zhang Jian all have a skill, and they have all been extremely down-and-out, and in the eyes of many people, they are like mustard.

But in Zheng Ji's view, the most powerful thing about these people is that they can get things done.

As long as they are given directions and requirements, these people can think and do their best, and now Fengju wants to develop new weapons, and it is the time to use these gentlemen.

She didn't know about the bed crossbow, but she knew that gathering the strength of everyone would be much better than fighting alone.

Seeing that Du Fengju was still hesitating, Zheng Ji thought for a while and said, "If Mr. Du has any concerns, why don't you send these people to Mr. Du's mansion?"

Feng Ju has changed his identity, and everything that goes with it is ready.

Of course, Mr. Du Duan of Wuge has a place to live in Jingzhao, which is not far from Wuge.

It's just that this place is quite inconvenient.

You must know that Jingzhaoju is not easy, and the residence of these two courtyards is too small, and I am afraid that it will not be able to accommodate so many gentlemen.

Moreover, the person behind it has let Feng Ju enter the Wuge Treasury, and he must also closely monitor his movements.

If these gentlemen go to Feng Ju's side, I am afraid that they will also attract the attention of the people behind them.

Zheng Jidao knew that Feng Ju actually lived in Taifu Mansion, but she shouldn't have known it.

Du Fengju quickly made a decision, shook his head and said, "Thank you Your Highness for your kindness, my residence is not suitable for developing new weapons. In that case, it will bother Your Highness."

Pei Yanshan, who was also dressed in disguise on the side, moved his lips, but the words did not come out.

Childe thought much more than him, and since Childe agreed, it means that going to Princess Changding's Mansion is the best way.

However, isn't Childe really worried about revealing his identity?..

When Zheng Ji heard his words, a smile immediately spread in his eyes, and his tone flew a little: "In this way, the main hall will make them prepare well."

She was really happy in her heart, thinking that she might be able to help Feng Ju, and even more Feng Ju agreed to enter Princess Changding's mansion.

Even in the capacity of Mr. Du Duan.

Feng Ju entered her mansion, so she would have more time to spend with him.

The mother concubine said that feelings are all about getting along, and having more contact with Feng Ju can be regarded as her selfishness.

Thinking of this, Zheng Ji even had a smile on his eyebrows.

However, she still remembered the reason why she came to find Feng Ju this time, so she said, "Mr. Du, are you willing to go with this hall to meet someone?"
