As soon as Emperor Qianwu took two steps, he heard a "boom" explosion.

I saw a flash of fire rising into the sky, and the plane was blown to pieces, which looked extremely tragic.

"Long Wind!"

"Brother Jiu!"

"Your Highness!"

“……”

The crowd screamed and panicked.

With such an amazing explosion, everyone's hearts sank to the bottom.

Normally, with such a fall from a height, such a terrible explosion, it is almost impossible to survive.

Even if Li Changfeng is an otherworldly existence, it is very dangerous.

Everyone was very nervous.

Just when everyone was frantically rushing away, I saw a figure slowly walking from a distance, its figure and dress were exactly the same as Li Changfeng.

Emperor Qianwu was shocked and said, "Changfeng? ”

Li Changfeng knew that everyone was concerned about his safety, so he rushed to it with all his strength and shouted from afar: "I'm fine, everyone rest assured!" ”

Hearing him say this, everyone's hanging hearts were relaxed.

In a few breaths, Li Changfeng had already come to everyone.

Emperor Qianwu looked up and down, and saw that Li Changfeng was unscathed, and even the clothes on his body were neat, so he breathed a sigh of relief and said with concern: "You're not injured, right?" ”

Li Changfeng said lightly: "Father, with the strength of his son, how can he be injured?" ”

After speaking, Li Changfeng looked at He Yongyan.

"There are several problems, first, the rear tail is too small, and the lift increase in the air maneuver state is limited, which makes the aircraft easy to lose control."

"Second, the engine power is insufficient, which is manifested in the fact that the speed is not high enough, resulting in insufficient power, and it is easy to lose power when the action amplitude is too large, which is an important reason for the plane crash."

"Third, the counterweight is uneven, the nose is heavy and the tail is light, and it is easy to get into the head."

Emperor Qianwu, Li Jianye and the others originally had a stomach to ask, but seeing that Li Changfeng and He Yongyan were discussing so seriously, several of them shut up and remained silent.

Li Changfeng continued.

"Fourth, the wind resistance is too great! Remember, design a streamlined look! In this way, the resistance will be less, but unfortunately we can't build a wind tunnel, otherwise we can see the air flow more intuitively...... Don't ask me what a wind tunnel is, it's always the details that need to be improved! ”

"Fifth, the control is too sensitive and the margin is too small, who can control it so accurately? This aspect needs to be improved as well! ”

“……”

Li Changfeng took the trouble to describe in detail one after another, and raised all the problems he found during the test flight.

In the end, Li Changfeng concluded: "Overall, the results of this test flight are still very satisfactory, at least they have flew, which is already a huge progress!" ”

Then, Li Changfeng patted He Yongyan on the shoulder.

"How? Remember, right? ”

He Yongyan nodded heavily: "Remember!" Remember! I already know the direction of improvement, and soon the second prototype will be built, and when the time comes, I will try again with His Royal Highness! ”

Li Changfeng said with a smile: "This is natural, but next time this prince hopes to start a test flight with a full load." ”

"Your Highness, don't worry, it's definitely no problem!"

"Okay, the prince is waiting."

With Li Changfeng's encouragement, He Yongyan took people to the research center.

Only then did Emperor Qianwu speak: "Stinky boy, I'm scared to death!" ”

Li Changfeng said with a smile: "Father, just put your heart in your stomach, with such a height and such explosive power, it is impossible to hurt your son." ”

Li Jianye asked eagerly: "Brother Jiu, when will the plane be produced?" When will the Daqian Air Force be equipped? ”

Li Changfeng said helplessly: "The plane is much more expensive than the Changfeng car, and it costs hundreds of thousands of taels of silver at the bottom, what are you doing with this thing?" To fight the natives on horseback? It's not such a waste of silver! It's not time to equip the Air Force yet! ”

“……”

Several people left the research institute while discussing.

Then Emperor Qianwu called Li Changfeng into the car alone and ordered everyone to stay ten zhang away from him.

Li Changfeng was surprised: "Father, what are you doing?" ”

Emperor Qianwu said: "Changfeng, tell me what kind of research you are doing in the deep mountains and dense forests, mysterious and mysterious." ”

Li Changfeng suddenly fell silent.

From the very beginning of the nuclear weapons program, Li Changfeng kept it strictly secret.

Although the guards of the scientific research institute are all people of Emperor Qianwu, out of trust in Li Changfeng, it is also to prevent the guards from knowing too many secrets about the scientific research institute.

Therefore, these people never inquire about the affairs of scientific research institutes.

Emperor Qianwu will not deliberately investigate, but will only judge based on clues.

Then he discovered something extraordinary.

So Emperor Qianwu was interested and took this opportunity to ask.

It's not that Emperor Qianwu doesn't trust Li Changfeng, but he is afraid that Li Changfeng will take risks by relying on his own strength, and today's incident is a good proof.

After pondering for a moment, Li Changfeng decided to tell Emperor Qianwu about his plan and asked, "Father, do you think the immortal cultivators will be blown up?" ”

Emperor Qianwu was a little surprised that Li Changfeng asked this, but he still replied patiently: "Of course you can!" When you were in the Wako, weren't you the one who killed Amaterasu Shrine with a dynamite pit? As long as the explosion is large enough, it will definitely be killed! ”

Li Changfeng smiled and asked again: "Father, do you think it is possible for a human immortal to be blown up?" ”

Hearing this question, Emperor Qianwu was stunned for a long time before he spoke.

"Impossible! It's absolutely impossible! Human immortals are truly transcendent beings, how can they ......?"

Speaking of this, Emperor Qianwu's eyes widened suddenly, a pair of tiger eyes stared at Li Changfeng's eyes, and asked in disbelief: "During this time, wouldn't you just study things that can blow up immortals?!" ”

Li Changfeng nodded seriously: "That's right!" ”

Emperor Qianwu was stunned for three breaths before he let out a burst of exclamation.

"It's true!"

"Are you crazy? What are you doing researching this!? ”

"Which human immortal will passively wait for you to blow up?"

"Besides, how many explosives do you need to kill a human immortal?"

“……”

After a burst of exclamations, Emperor Qianwu gradually came back to his senses.

He stared at Li Changfeng with an unprecedentedly serious expression, and said in a deep tone: "Changfeng, listen to me, this is simply impossible!" And you can't do that, if those immortals know, how can you live? ”

Li Changfeng chuckled and shook his head: "First of all, this is completely achievable!" Secondly, those immortals would not know, and even those who participated in the research only thought that it was just a huge special bomb. ”

Speaking of this, Li Changfeng said: "Even if it is a human immortal, it can't control us, our fate must be in our own hands, and when this weapon is researched, we will have the confidence to fight with human immortals, what Bai Yujing, what barbarian temple, there is no need to be afraid at all!" ”

Emperor Qianwu looked excited: "Really?! ”
