For Saint Jiu, the power of this bow and crossbow obviously did not meet her requirements.

But for Ge Qiu and Ling Yun, the power of this kind of bow and crossbow was already quite terrifying.

When Sheng Jiu said these words this time, the two of them were really shaken.

After the drill and explanation, seeing the two of them stunned in place, the bow and crossbow in the hand of the Holy Nine were directly thrown to Ling Yun: "In the future, you will use this kind of bow and crossbow to train yourself, and now in your situation, when training, you must grasp the direction, such as starting from accuracy and strength." ”

"Besides, although the bow and crossbow that I have improved are still shoddy, as long as you get started, you will be able to control the strength and accuracy well, of course, as long as you can master it well, you will find that the speed of each arrow fired will also be reduced a lot of time."

"It's the master!" After Ling Yun was taught, he nodded seriously.

Standing aside, Ge Qiu was thoughtful and couldn't help asking, "Saint Nine!" I wonder what this tool is called after you improved it? ”

"You can call it a crossbow." Sheng Jiu originally wanted to talk about the revolver crossbow, but after thinking about it, he changed the name, after all, the current bow and crossbow could not reach the effect of the revolver crossbow.

"Crossbow! That's a good name! Ge Qiu stroked his beard and nodded.

"That's right! At the end of today's exercise, you can disassemble them and place them separately, put the bow and crossbow directly into the storage ring, and as for this important accessory, at the end of each day, you throw it in kerosene and soak it overnight, wash it a little the next day, and then use it again. Thinking of something important, Sheng Jiu said again.

"Master! Why is this stuff soaked in kerosene? Ling Yun didn't understand what Sheng Jiu meant, so he asked.

Sheng Jiu replied: "On the one hand, this can strengthen the toughness of the iron pear wood, in order to achieve the effect of black iron, and on the other hand, it can be soaked in kerosene for a long time, which can reduce the wear and tear between the parts. ”

In this world, there is no such thing as engine oil, so in order to reduce losses, Sheng Jiu came up with this method.

Ling Yun didn't seem to understand, but Ge Qiu had a look in his eyes.

The wear and tear of the appliance itself is an indisputable fact, but most people don't know how to maintain it.

For example, the current Cross Repeater, if Saint Nine didn't say this, and Ling Yun threw this thing directly into the storage ring after his daily practice, then within a few days, the wear and tear between the various parts would cause problems with the Cross Repeater.

If it is a refiner, when building a tool, they can inject a small amount of qi veins as the protection of the tool, but the problem is that there is no refiner here, so if you want to maintain the equipment you use, you can only rely on conventional methods.

But even so, the conventional method is not so easy to think of.

"Buildable material!" Stunned in place for a few seconds, Ge Qiu secretly praised Sheng Jiu in his heart, but he didn't say it. Who let the Holy Nine lose his temper with him before.

"Ge Lao! Are you tired now? After explaining the things he had explained, Sheng Jiu looked at Ge Qiu again.

"If you have something, just say it, I'll listen!" Ge Qiu looked at her and replied.

"If you're tired, go and rest first, and if you're not tired, work hard and make the rest of the things." As soon as his words fell, Sheng Jiu said directly.
