After selling a bicycle to each of the boys, Wu Fan and Xia Ziyan waved goodbye and returned to their teacher's attic contentedly.

"Knock knock!"

But not long after he sat down, there was a knock at the door.

Wu Fan opened the door and found that it was He Hai standing outside the door.

"Grandpa Headmaster?!" Wu Fan said in surprise.

"Fan'er, you're back. He Hai responded with a smile.

Wu Fan invited He Hai into the door, and after making a pot of tea for him, he asked, "Grandpa the principal, is there something wrong with you coming to me?"

He understands how precious his time is, and the headmaster is definitely 'going to the Three Treasures Hall for nothing'!

"Hahaha, Fan'er, grandpa has a good thing to share with you today. He Hai leaned close to Wu Fan's ear and said mysteriously.

"What's good?"

Wu Fan was also interested, and hurriedly asked.

"Hahaha, Grandpa has found something that can greatly improve the combat effectiveness of the Tianchen Kingdom, and with it, we no longer have to be afraid of the magic army of the Red Fire Kingdom. Ha Hai laughed.

"Huh, what's that?"

Wu Fan knew that He Hai was selling Guan Zizi, and he didn't break it, so he followed his mind and asked.

"Hey, that's it!"

He Hai took out his 'confiscated' bicycle from the space ring, stroked it triumphantly, and said: "It's called a bicycle, it is a very unique vehicle, it doesn't need to rely on any animal power, it can move forward extremely fast with human power alone, the speed is much faster than that of low-level magicians, and it is extremely labor-saving. After passing a certain level of proficiency, the Legion of Mages can ride it to move and cast spells, and its agility and mobility will be greatly improved......"

He Hai seemed to have opened the conversation, and talked endlessly to Wu Fan about the benefits of bicycles, talked about the proudness, and even demonstrated it with a smile on his eyebrows, looking like he praised it vigorously.

Wu Fan's eyes widened, staring blankly at the bicycle under He Hai's seat, unable to believe what he was seeing.

How did the principal's grandfather know about this bicycle in just one day?

And on the basis of it, so many combat plans have been studied?

I have to say that Wu Fan was shocked!

As the initiator of the bicycle, he didn't expect to be able to 'play' like this?

However, after carefully analyzing the combat plan listed by He Hai, the more Wu Fan pondered, the more he felt that it was extremely feasible!

After all, this is a suppression at the level of science and technology, and it may really be able to create miracles in a short period of time!

At the same time, He Hai's recounting also opened up a new world for Wu Fan.

If even bicycles can be used in warfare, is it okay to have a weapon with a higher technology content than it?

In this way, even if the Red Fire Kingdom attacked the Tianchen Kingdom with all its might, with the defense and countermeasures of modern weapons, Wu Fan would not be so passive at all, and even the balance of victory would be tilted in his favor.

However, the scientific and technological content of this weapon must be well controlled, and if the span is too high all of a sudden, I am afraid that I will be at a loss for words......

He was bound by the traditional concept of the Magic Continent before, and he didn't think about it at all, and subconsciously considered it from the perspective of magic, warriors, etc., especially after hearing that the comprehensive strength of the Red Fire Kingdom was dozens of times that of the Tianchen Kingdom, he was even more uneasy.

Now after He Hai's unintentional mention, it has opened a new window for him.

For a moment, Wu Fan fell into deep thought.

“...... So, this bicycle has a lot of advantages, and I don't know who invented it. If we can find someone to make it, when the time comes, the strength of the Tianchen Kingdom will be increased by another ten!, but I guess the person who made it must be a certain refiner, and I will let someone find it tomorrow......"

He Hai said and spoke, suddenly stopped, he saw Wu Fan's absent-mindedness, touched him, and asked, "Fan'er, what are you thinking?"

"Huh?"

Wu Fan came back to his senses, scratched his head a little embarrassed and said, "I'm sorry, Grandpa Principal, I just got distracted, where did you go?"

He Hai said angrily: "I said that if I can find the person who made this product, it would be good to buy a few hundred more cars......"

Hearing this, a trace of inexplicable expression appeared on Wu Fan's face, he squeezed his face with his index finger, and said weakly: "That...... Bicycle...... I made ......."

"What did you say?!"

He Hai was suddenly startled and shouted.

Wu Fan sighed, he didn't want He Hai to be so embarrassed, but since he had asked about the main master, and this matter was also beneficial to the Tianchen Kingdom, Wu Fan couldn't continue to hide it.

He also took out a bicycle directly from the system space and explained: "Grandpa Principal, I made this bicycle just to make it better for the students to quench their bodies, but then it was seen by the students in other classes, and they loved it and wanted to ride it, so I made a more lightweight and comfortable bicycle......

Wu Fan told He Hai the general process, and at the same time let He Hai experience their special cultivation special overweight bicycle, and He Hai was just a simple magician, his physical fitness was naturally not as good as Wu Fan's, and he even struggled to push that bicycle.

"So, I used to get an axe at the class gate?"

He Hai's face was a little unnaturally flushed, he had been the principal for so long, and it was the first time he had been embarrassed in front of his juniors......

"No, no!"

Wu Fan hurriedly waved his hand and said: "My original intention of making it was just to assist the students in quenching their bodies, and I didn't think about anything else, but the principal's grandfather was only in contact with her for such a short time, and he was able to think of so many new combat methods, which really made the younger generation admire!"

What he said was true.

He Hai nodded slowly, and he didn't bother whether what Wu Fan said was true or false

Just go down the stairs.

"Fan'er, how did you come up with this novel bicycle?" Grandpa remembers that you had no interest in this before...... "He Hai asked.

Wu Fan replied: "I can't hide it, Grandpa Principal." Although I am already a one-star celestial master now, I am not satisfied with this, but want to climb to a higher peak! Therefore, I am working hard to cultivate and strive to become a two-star celestial master! However, a two-star celestial master needs two sub-professions, in addition to alchemist, the other sub-profession I chose is a refiner, and I have been studying and cultivating hard during this time, so I can be fortunate enough to make this bicycle ......"

Wu Fan said half-truths and half-truths, he is lying now, and he doesn't even have to type a draft.

"Fan'er, you should still be in the beginner stage, right? No wonder I can't even feel the slightest elemental power on this bicycle, it can't be regarded as a meta-weapon at all, it can only be regarded as a trick......

He Hai nodded suddenly in realization, and reasoned on his own.

When he said this, he saved Wu Fan a lot of saliva.

Wu Fan hurriedly replied, "Yes! I still need to work harder to cultivate!"

He Hai patted him on the shoulder and encouraged: "This is a good man! Before, your strength was progressing slowly, and you gave up on yourself, and the principal and grandfather didn't say much, I just hope you can live happily, but now that you have awakened, you must be even more indignant, make up for all the previous falls, and strive to surpass grandpa!"

"Yes!"

Wu Fan responded loudly.

He didn't know how strong the principal's grandfather was, but when his father was still alive, he once mentioned: "With the strength of one person, he has killed a bloody road among thousands of troops!"

If this were not the case, Wu Fan's father would not have survived......

However, now the principal's grandfather actually hopes that Wu Fan can surpass himself?

What a high hope is placed on him!

For a while, Wu Fan had some tears in his eyes.

He knew how incompetent and cowardly the original owner was before he crossed over!

Even so, the principal's grandfather is still constantly protecting himself and shielding himself from the wind and rain......

"By the way, Fan'er, you seem to have gone to the palace today, what is Your Majesty looking for you?" He Hai suddenly remembered something and asked.

Wu Fan replied: "That's the case, Xia Ziyan was taken back to the palace yesterday, and then ......"

Half an hour later.

He Hai nodded clearly, he frowned and said, "Fan'er, you are a little reckless this time! Although you are a Heavenly Master, you can't treat Your Majesty like this, at least you still have to do the kung fu on the surface...... But if you are lucky, Your Majesty's grandfather knows that he is generous and simple, with an easy-going personality, and he is a wise man, except for a little too much doting on his daughter......"

Wu Fan thought so, this king's father almost blinded his titanium alloy dog eyes today!
