In order to show his sincerity enough, Cheng Yanjin spent nearly three days setting up a complete study plan for Su Wen.

Each step has been carefully set up by him in combination with his years of experience, and it can be said that he has put a lot of effort into it, and his purpose is to make Su Wen feel his intentions.

But.

Cheng Yanjin soon discovered a terrifying fact, the set he tried his best to make was of no use to Su Wen.

Because......

The other party's learning speed is too fast, even beyond the scope of normal people.

Over the years, Cheng Yanjin has led many soldiers, many of whom are now in high positions, and he has seen a lot of extremely talented people, but he has never seen anyone who can progress as fast as Su Wen.

He only demonstrated many moves, and Su Wen could learn them very easily, and he could extend many other moves with this move.

Coupled with Su Wen's terrifying power, in just half a month, Su Wen has grown from a person who barely understands martial arts to an existence that can be compared to Cheng Yanjin.

And.

If Su Wen wanted to dress up Cheng Yanjin desperately, maybe Cheng Yanjin was really not his opponent now.

For all this, Li Er and Wei Zheng just watched silently, and they didn't know when cooking and washing clothes became Wei Zheng's exclusive thing.

The days passed like this, and in the blink of an eye, a month passed......

……

"Whoosh!"

A sharp sound of breaking the air suddenly came, and a feather arrow quickly crossed an arc in the air, and slammed into the arrow target not far away.

Merely.

The position in the middle of this feather arrow is the edge of the target, and as long as it is slightly off, the arrow will not be able to hit the target.

"Good!"

Cheng Biting Jin's loud voice came faintly, he stared and turned his head to look at Su Wen with a calm face beside him, and his eyelids couldn't help but jump wildly.

"You know what? I have never seen a man who can do this in an hour, and the average person who first learns a bow and arrow will not be able to hold a bow and arrow for a long time! ”

When he said these words, Cheng Yanjin couldn't help but gasp.

During this time, he had seen how evil Su Wen had become.

But despite this, he couldn't calm down when he saw the scene in front of him.

"It's been so long and I've finally come across my favorite thing!" Su Wen looked at the bow in his hand, showed a hint of a smile and nodded.

"Brother Su likes bows and arrows?" Cheng Yanjin looked at Su Wen curiously.

He had always thought that with Su Wen's qualifications, he should like the pleasure of punching to the flesh, that is, he might become a person with the same style as himself.

"Not only bows and arrows, darts, hidden weapons, etc., but what man didn't dream of being a ninja when he was a child?" This sentence was said by Su Wen to himself.

"Ninja?" Cheng Yanjin frowned, and then his face showed ecstasy.

Every time he heard Su Wen say very novel words, he often gained a lot of knowledge, which had become a habit for him.

So.

When he heard the word "ninja" that he had never heard before, he instinctively thought that he might gain some knowledge today!

"Yes! This kind of product comes from a small island country, you won't understand, because according to time, we are still their teachers, maybe these people are desperate to run over at this moment! Su Wen sneered and explained a little vaguely.

For this matter, Su Wen has always secretly kept it in his heart, since he has come to the current Tang Dynasty, many things will inevitably change dramatically.

Thereinto...... These students he just talked about, Su Wen didn't plan to treat them well!

"Alright...... It's useless to think about it, but when it comes to this bow and arrow, I have some new ideas! Su Wen didn't care about Cheng Biting Jin, who was in deep thought, but weighed the bow in his hand and said very seriously.

Su Wen had only accidentally seen the relevant records of such a thing as a divine arm crossbow, and he probably knew how this thing worked.

Although he didn't have detailed drawings now, with such a concept, he was confident that he could turn it into reality, and even if it might not be as powerful as he remembered, it was still possible to make the bow and arrow easier.

What's more.

Su Wen clearly remembered that there were some things in the newbie gift package that the system gave him at the beginning, such as fiber rope and titanium alloy materials that were better than the bowstring in his hand!

It's not much, but you should be able to make a bow or two.

"What new ideas?" As soon as he heard that Su Wen wanted to do something new, Cheng Yanjin immediately came to his senses.

This is his favorite part!

"Just follow me!" Su Wen smiled mysteriously.

In the following days, in addition to sleeping, Cheng Yanjin was with Su Wen almost all the time, from building the furnace, to making the blower, and finally to studying how to make the new bow and arrow, this series of things consumed a lot of time.

By the time the first slightly rough bow and arrow of a completely different style appeared in Su Wen's hand, nearly two months had passed......
