The three thousand female officials are the most intelligent demon spirit girl selected from the people of the Demon Spirit clan by using the power of the Emperor.

The Emperor of the Abyss achieved the Emperor with his spiritual power, and also relied on his mental power to command millions of troops. Therefore, under the scanning of mental power, it is clear who is smart and who is stupid.

The Emperor of the Abyss knew very well that he did not need these demon spirits to fight for him, but only these three thousand female officials needed to manage the demon spirit clan well, plant shrubs for the Abyss clan, and obtain food.

Wisdom is the most important thing. Only smart people can manage the demon spirit clan well. Therefore..., including the Demon Spirit Queen, the wisdom of these three thousand female officials is absolutely not to be questioned.

Today, the wisdom of these three thousand female officials helped Chu Xingyun a lot.

With his brainstorming, various fantasy ideas were proposed one after another. Although experimental verification has not been carried out, Chu Xingyun knew it was feasible with a little reasoning.

Excited, Chu Xingyun took out the ice marrow rarely and poured a small cup each as a reward for everyone.

Although there are three thousand people here, the Demon Spirit Clan is too small. For Chu Xingyun, it is just a small cup for each person, but for the Demon Spirit Clan, it is a big pot.

Drinking ice marrow, everyone discussed it enthusiastically, and the seminar was held for nine days and nine nights.

For nine days, no one left or sleeped. Everyone was thinking about it, constantly modifying the previous design and striving for excellence.

In normal times, even a Nirvana warrior would not be able to stay asleep for nine days and nine nights, but he was still so energetic, but ice marrow wine made everything possible.

Finally, when nine days and nine nights passed, a brand new arrow was designed.

Although it has not been mass-produced yet, it is definitely a piece of cake for Chu Xingyun to manufacture a few pieces separately for testing.

Under Chu Xingyun's order, the Abyss Emperor sent troops to send a large number of arrow bamboos, and the Demon Spirit Queen also sent people to get a large amount of materials.

According to the final design drawing, Chu Xingyun quickly refined an arrow.

First of all, the Jifeng Rui Golden Arrow. With everyone's modifications, the range, speed, and penetration of the Jifeng Rui Golden Arrow have been greatly increased. After all, with the defense of the two-winged Tianlang, it is basically difficult to survive as long as it is pierced.

The two-winged Tianlang has almost no armor. Once it is shot, it loses its ability to fly and falls directly from a height of hundreds of meters. Even if it is not dead, it will definitely be half-dead. The guards of the bow and arrow troops can easily kill them.

Therefore, this sharp golden arrow actually does not pursue shooting. It can kill the winged Tianlang and make it lose its flying ability, which is equivalent to killing the other party.

After the rate of fire and penetration are enhanced, the range is extended to a distance of kilometers, which is too important for archers. The rate of fire and range are the life of archers!

After improvement, the Jifeng Rui Golden Runes are no longer the same. They are no longer the simplified version of the previous one, but the complete version, the real Jifeng Rui Golden Runes.

Compared with the simplified version of the Rapid Golden Arrow, although the new version of the Rapid Golden Arrow is more precise and more difficult to produce, the data has been greatly improved.

The rate of fire is doubled, the penetration force is doubled, and the range is extended to kilometers. The overall performance is increased by as much as three times.

After the transformation of the Jifeng Rui Golden Arrow is completed, the next step is to produce the Jifeng Rui Golden Arrow.

Take a piece of bamboo tube with a thickness and length of thumb, and carve red flame runes on the surface. The bamboo tube is filled with iron sand. On the inner wall, a first-grade spirit stone is inlaid with strong burst runes around the spirit stone.

A groove was carved on the outer wall of the bamboo tube, which could just inlaid the sharp golden arrow on the groove. Just press it gently, and the groove can be stuck on the arrow shaft. If you don’t break it hard, it will not fall off.

After taking a battle bow, Chu Xingyun picked up the newly made arrow with a piece of bamboo tube tied to the arrow shaft.

With a bent bow and arrow, Chu Xingyun shot out an arrow.

Chih...

With the sharp sound of breaking through the air, the arrow instantly turned into a golden light, and in the blink of an eye it reached a height of hundreds of meters away.

Although the range of the Qifeng Rui Golden Arrow can reach a distance of up to a kilometers after being improved, after being tied to the bamboo tube, its speed, penetration power, and range have been greatly reduced.

Looking at the arrows in the air, all the demon spirit officials clenched their fists nervously.

This small arrow was designed by the three thousand female demon spirit officials for nine days and nine nights. If the power is not as good as everyone imagined, it would be a pity.

Finally, under the gaze of three thousand female officials, the sharp golden arrow disintegrated in the air.

As the arrow disintegrated in the air, the bamboo tube stuck on the shaft fell off. Turned around and pointed one end of the bamboo tube to the ground. At the same time, the red flame runes on the surface of the bamboo tube lit up.

Ga...

With a strange roar, the bamboo tube suddenly spewed out a tongue of flame towards the end of the sky, and a shrill and strange scream shot towards the ground.

Seeing this scene, all the demon spirit officials couldn't help but cheer. Obviously... the second-level arrow was successfully activated, and the red flame rune was officially activated.

The flame tongue sprayed at the end of the bamboo tube was the effect of the red flame rune. Under the push of the red flame, the arrow turned into a red light and swooped towards the ground.

boom!

Finally, the arrow fell on a rock in the distance, and it exploded with a violent impact.

Amid the violent explosion, a dense rustling sound like a shower, made all the demonic female officials scream in excitement, and the scene was filled with joy.

Chu Xingyun was not in a hurry to be happy. Although the entire launch process was very smooth, the specific power must be carefully checked before going to the rock.

I quickly rushed to a few hundred meters away, beside the huge rock. Looking closely, the originally smooth and flat surface of the rock was now extremely mottled.

Fist-sized dents were densely distributed on the surface of the rock, and dozens of stone pieces as big as palms fell on the ground around the rock.

Seeing this scene, Chu Xingyun could no longer suppress the surprise in his heart...

After the red flame rune is activated, the explosive rune with the first-grade spirit stone as the core inside the bamboo tube has been opened. Once the bamboo tube is subjected to a violent impact, it will be instantly activated.

As the name suggests, the violent explosion of runes will be generated. If superimposed with the Red Flame Array Talisman, a violent explosion will be generated. The iron sand in the bamboo tube will scatter and cause damage to surrounding targets.

Looking at the rock surface, the deep pit as big as an adult fist, Chu Xingyun was so excited that he didn't know how to express it.

If this falls into the formation of the Tianlang Army, then within a radius of ten meters, there will be no expectation that there will be a Tianlang warrior who can stand. Even if he does not die, he will definitely be covered in wounds and will not be far from death.

Just as she was happy, the Demon King also arrived at the scene. After checking the power of the Red Flame Explosion Stripe, she frowned...
Chapter completed!
