"Grandfather, you have worked hard. You have only worked hard for a few days. You have completed the transformation of my weapons, and you certainly haven't had a rest for a long time."

Hearing what Mufeng said, Zhang Fan also felt guilty.

After all, their weapon level has reached A9 level. If you want to upgrade, the requirements for materials are very high, and it takes a lot of effort.

At this point, Zhang fan can see the color of exhaustion from the look of Mufeng, which is heartache.

"Ha ha, what I am doing now is this profession. Don't worry. With my current strength, as long as there is no accident, living for one or two hundred years is not a big problem. Building various weapons is my profession. The more challenging and difficult it is, the more it can stimulate my fighting spirit. Otherwise, after I have leisure every day, what can I do?"

Looking at Zhang Fan's worry, Mufeng is also very moved.

"You're always like that. Although it's true to say so, it takes a lot of mental energy to build weapons. Especially for my battle spear, when you built it, it reached A9 level. If you want to strengthen it, you don't know how much effort it takes. In a short period of time, it will certainly not be able to recover. "

Zhang Fan is helpless at this time, but his grandfather Mu's personality is like this, otherwise, he will not stay in the Star City Institute to refine various weapons and other advanced weapons.

"Ha ha, OK, Grandpa, listen to you. After going back this time, I will have a good rest. At that time, you can live directly in the villa where you are, and protect your parents. Aren't they? Anyway, I'm a little bored at the Star City Institute alone.

Come on, this is your spear. See if it fits

Looking at Zhang Fan, Mufeng also said with a smile at the moment. Then he had a light in his hand. A pale yellow spear appeared in his hand and handed it to Zhang Fan.

"So much weight?"

As soon as he got it, Zhang Fan was also a stagger. Obviously, the weight of the spear exceeded his imagination.

"Ha ha, didn't you always say that the spear was too light? Some slight changes have been made to this spear and abrasives. In terms of material, I have added a lot of other alloy materials, which have very good compatibility in density and can be integrated into black gold.

This spear now weighs 1500 kg. I believe it will be enough for you to use it for a long time. This is the most suitable weight for you according to your present strength and comprehensive judgment.

At the beginning, it may be a little bit uncomfortable, but I believe you will soon be able to adapt. Moreover, I have made some changes in the spearhead, which is more sharp than before.

Including the sawtooth and blood trough, I have also reconstructed it. It can be said that as long as you are scratched by your spear, even if you scratch a little skin, you will not be able to recover in a short time, and the lethality will be increased a lot. "

Mu old at this time saw Zhang Fan's embarrassment, also said with a smile.

"Poof!"

Taking a deep breath, Zhang Fan also directly picks up the spear and stabs it out in front.

All of a sudden, there is a crisp sound in the space, which makes the sails leak a satisfied look.

After the transformation of the spear, after holding it in hand, it also has a sense of heaviness, which is exactly what we need to set sail.

After all, to his current strength, many weapons used by other warriors have reached about 1000 kg. The increase in weight can sometimes increase their own strength to a certain extent.

"Thank you, Grandpa mu. I like it very much."

Zhang Fan also said with sincere thanks.

"Hehe, don't be so polite with me. What's more, I made a set of throwing knives for you with the remaining materials. There are 36 pieces in total, which should be enough for you to use.

Although the level of this set of throwing knife is not up to A9, but the material used is comparable to A9 level, I believe it can increase your many strength.

I think, if you can directly control 36 throwing knives to the extreme peak, then the strength, really do not know what will be achieved. I'm looking forward to that day. "

Looking at Zhang Fan, Mufeng also said with a smile, and then he directly took out a box with 36 pieces of dark yellow throwing knives in it to make Zhang Fan's eyes bright.
