Chapter 1303 (1/2)

Under the continuous bombardment of 3000 arrows, the boulder with a diameter of more than two meters has been turned into gravel all over the ground and completely disintegrated.

The reason why it has such great power is that the power of the red flame Rune and the fierce explosion rune is on the one hand, but more importantly, it is the one spirit stone that the fierce explosion Rune detonates.

Inspired by the strong explosive rune, a pinling stone explodes violently, pushing the iron sand in the bamboo tube, causing great damage to the target

Unconsciously, more than 20 days have passed.

with the cooperation of 3000 female officials, Chu Xingyun didn't worry that it would be too late. Therefore, in the next six days, everyone had a big sleep, and then 3000 female officials got together again to continue to strengthen.

With only three days left, the new type of arrow was finally finalized.

In terms of runes, there is nothing that can be changed. The patterns of fast wind, sharp gold, red inflammation and fierce explosion are all perfect after 50 million years of human exploration.

Although it is not absolutely impossible to improve, I am afraid that we can not make any progress without tens of millions of years.

The only thing that can be changed is to optimize and improve the shape and layout of arrows by combining the wind way of the demons.

In addition to the shape and layout, the iron sand inside the bamboo tube has also found the best alternative.

In the underground world, there is a poisonous river. The reason why the river is highly toxic is that the river flows through an underground desert, and the desert is full of dark green gravel.

The poisonous river was called the river of the underworld by the demons, and the gravel was called the hell sand by the demons.

Every day, the river Styx carries a large amount of sand and flows into the underground desert, which is formed by the accumulation of sand carried by the river for thousands of years.

After hundreds of millions of years of accumulation, the Mingsha is almost inexhaustible.

According to Chu Xingyun detection, these dark green gravel, contains a strange toxin, once stained with blood, it will let the blood coagulate.

As a creature, when blood cannot flow, it can only die.

If it was the limbs that were shot by the gravel, maybe it was not a big problem. It would not be fatal if an arm or a thigh was lost.

But once shot in the trunk or head, it's all over and you'll die.

With these grains of sand, there is no need to spend time refining iron sand.

Most importantly, the sand is inexhaustible, inexhaustible, and increases every day.

When there were only three days left, Chu Xingyun finally determined the final version.

With Chu Xingyun's order, 3000 female officials immediately started to produce this new type of arrow at full speed.

Each demon female officer can produce more than 100 new arrows every day. After three days, a total of one million new arrows were produced, enough for three rounds of competition.

Finally, a million new arrows were produced, and a million sharp arrows were piled up into a hill.

Looking at the mountain of new arrows, all female officials are very happy. With their Nirvana strength, this work is not enough to make them feel tired.

Looking around for a week, Chu Xingyun said, ”OK, the new type of arrow has been successfully developed. Next It's time to name the new arrow. ”
