After Su Wen's consent, Li Er and Cheng Yanjin began to tailor various equipment for themselves in the following time, and always used Su Wen's previous tools to build bows and arrows.

Of course.

These things are all common in the army, whether it is armor, broadsword, or bow and arrow.

Since the material they needed this time was the titanium alloy left over from Su Wen's previous time, plus it would take a lot of time to make use of that tree to copy.

Therefore.

For ten days, they just built a complete set of equipment.

And.

This is still in the absence of the pursuit of excellence, if you are comprehensive, it is estimated that a month may not be able to create a complete set of equipment.

These days.

Wei Zheng has always followed Cheng Yanjin and them, and for this, he has suffered a lot of crimes.

There's no way around it.

In addition to following Cheng Yanjin and Li Er, he only had a choice between Su Wen and the Turkic man, compared to these two people, he would rather be sweaty from the heat every day.

I said...... How is this arrow a little different from what we usually see? Wei Zheng wiped the sweat from his forehead, picked up a feather arrow that Cheng Biting Jin put aside very curiously, and asked with a frown.

Just as he picked up the arrow, Cheng Yanjin's face changed, and he immediately opened his mouth to stop him: "Don't move!" Be careful with ......"

Behold.

Before he could finish his words, Wei Zheng's fingers lightly touched the arrow of this feather arrow.

"Hiss......"

Wei Zheng's fingers were stabbed painfully, and he instinctively retracted his hand.

But.

Before he could withdraw his hand, a sharp pain quickly came from his left hand, which was holding the shaft, and it didn't take long for a trace of blood to drip from his palm.

"Don't move!" Cheng Yanjin hurriedly walked over and carefully held the feather arrow from both ends.

"Take it out...... Remember, push hard in the direction of the tail of the arrow! ”

The sweat on Wei Zheng's forehead seemed to be more......

He never thought that this feather arrow, which looked very different, would still have such a mechanism hidden, at this moment, dense spikes were standing upside down on the shaft of the entire feather arrow, and many of these spikes had already pierced into Wei Zheng's palm.

If he were to forcibly take his hand out, I was afraid that the wound would be even more wide.

"What's wrong?" It was at this time that Li Er, who was concentrating on making his inner armor on the side, walked over quickly.

At this time, Li Er** was wearing his upper body, and he looked visually impactful with his muscles.

Especially when covered in sweat, if there are women from the Tang Dynasty standing here at this time, they will definitely be fascinated by Li Er's seductive figure.

Maybe...... I just drooled and pounced on it!

"Be careful...... Right...... Slowly...... Slowly loosen it! Cheng Yanjin didn't have time to take care of Li Er, all his attention was on Wei Zheng's hands at the moment.

After a long time, Wei Zheng finally took his palm off the shaft of the arrow, and the blood on his hand did not stop almost from beginning to end.

I don't know if it was because of excessive blood loss, or if Wei Zheng was frightened, his face was very pale at the moment, and he looked a little gloomy with sweat.

"What do you say...... Isn't it good to look at it honestly? How can this thing move? Cheng Yanjin looked at Wei Zheng with some fear and blamed.

This is a special feather arrow that he created according to Su Wen's previous theory, and it was also something that he and Su Wen had barely made after nearly two months.

Moreover.

So far, this is the only one!

The reason why Cheng Yanjin brought it here is to take this opportunity to see if he can build a few more, if it weren't for the urgency of time, he would have used that tree, and he didn't have to work as hard as he did now.

"That's what you're talking about?" Li Er seemed to know the existence of this thing, and looked at Cheng Yanjin and asked with some curiosity.

He seemed a little indifferent to Wei Zheng's injury.

"Yes, Your Majesty! In Su Wen's words, the lethality of feather arrows designed in this way can be maximized! Cheng Yanjin said as he carefully picked up the feather arrow again.

"Your Majesty, please see, there is a small mechanism on this feather arrow, and the switch of the mechanism is on the arrow, once the arrow is blocked, the mechanism will be opened, and a large number of spikes will immediately appear on the entire arrow shaft!"

"Your Majesty, please think about what it would be like if this feathered arrow were shot at the Turks, and they wanted to take it down. Moreover, Su Wen also said...... Consider applying poison to this spike! ”

From the time Cheng Yanjin began to introduce this feather arrow, Wei Zheng's attention had been on him, and when he heard the last sentence, Wei Zheng's face seemed to become even paler.

？？？？？？

Is this all a human thing?

Fortunately, there is no poison on it, otherwise, I wouldn't have to burp directly today?

"Hmm......" Li Er nodded meaningfully.

Should it be said or not.

Su Wen still likes these ways, he understands very well that if he is not ruthless, he will be trampled under the feet of others and trampled by others!

"So be it...... The second set of armor is already being crafted, and the rest of the materials are almost enough to make weapons, so let's use that tree to grow this thing in the future! Li Er looked at Cheng Yanjin with great satisfaction.

"Yes!" Cheng Biting's eyes flickered.

The reason why he took advantage of the situation to say so much today, coupled with the fact that Wei Zheng inadvertently embodied the value of this feather arrow, was to make Li Er say this.

According to Su Wen, there is not much time left for them now, and there are still a few days at most before they can get out of here.

Therefore.

Every day is very precious to them, especially when it comes to using the tree.

This is still in the case that Su Wen does not need it, and if Su Wen wants to use it during this period, their time will be even more urgent.

Wei:?????

What do you mean two sets are about the same?

"Your Majesty, if we can get out of here now, do we have to think about what will happen after we get out?" Wei Zheng bandaged the wound with the brocade handkerchief he had brought with him with some heartache, and then came to Li Er and asked.

It's been so long, and no one cares about his injuries!

The world is hot and cold......

"We have already discussed this matter, don't care about anything after we go out, we must first determine the current situation in Chang'an, if Chang'an is really occupied by the Turks, we must immediately assemble a large army to counterattack!"

"It's only been half a year, even if the Turks occupy Chang'an, their roots are not stable, we still have a great chance to take Chang'an back!" Speaking of this, Li Er's expression immediately became gloomy.

Cheng Yanjin nodded silently and did not speak.

Wei Zheng: I#¥&%.........

We?

Where are you?

Why don't you take me to play with anything now?
