A plague dragon rat flew toward Ning Qi. Ning Qi cut it in half casually, then focused half of his attention on clicking on the details of the advanced mission.

"The host is requested to hand over the Wind Dragon Pearl found here to the Dragon Queen, the wife of the Demonic Dragon King of the Mountain and Sea Region, within one year. If the time exceeds one year, the mission will be considered a failure. If the mission is successful, an additional 500 Dragon Slaying Coins will be awarded.

, as well as the mission clues about the missing seven dragon balls in the dragon-slaying sword."

Ning Qi glanced at the seven holes on the handle of the dragon-slaying sword and frowned. This mission actually required him to come into contact with the Dragon Queen of the Demonic Dragon King in the Mountain and Sea Region?

Ning Qi seemed to remember that the black fire ghost dragon that died in his hands before seemed to have said that its father was the Demonic Dragon King of the Mountain and Sea Region?

A seventh-order BOSS-level dragon!

"There is also the Pearl of the Wind Dragon. Could it be that this is the reason for the mutation of the plague rats here?" Ning Qi glanced deep into the cave. I am afraid that there are more difficult guys waiting for him ahead.

All in all, the difficulty of this advancement mission is more than ten times more difficult than the previous Dou Master advancement to Grand Dou Master!

However, if the mission is successfully completed, not only can you advance and obtain 500 Dragon Slaying Coins, but you can also obtain mission clues to the long-missing seven Dragon Balls of the Dragon Slaying Sword. This is what Ning Qi values ​​the most!

If these seven dragon balls can be recovered, the dragon-slaying sword will exert its original power, and I am afraid it will be able to kill the dragon in seconds!

Thinking of this, Ning Qi planned to speed up the progress. He would first find the Wind Dragon Pearl, then clean up all the plague dragon rats here, and then go to the mountain and sea area. One year would be long or short.

Short, fortunately he had Xiao Zi, otherwise he would have wasted half of his time just rushing.

At this time, the huge Plague Dragon Rat King suddenly opened its eyes, and scanned its surroundings with its sharp little eyes. When it discovered that there were only a few dozen elite plague dragon rats left among the hundreds, it suddenly turned over and stood up.

It stood up, its huge fleshy wings spread out horizontally, and let out a sharp roar.

This sound directly reached the ears of Ning Qi, who was hundreds of miles away from here.

"It looks like it should be a BOSS-level plague dragon rat! The Wind Dragon Pearl should be there."

Ning Qi quickened his pace and easily dealt with the plague dragon rats he encountered along the way.

Half a day later.

Ning Qi finally reached the deepest part of the cave. When he saw the Plague Dragon Rat King, he was shocked. This is not a dragon rat. It is simply an uglier-looking giant dragon that can evolve a rat.

At this point, Ning Qi couldn't help but look at the giant dragon skeleton next to the Plague Dragon Rat King.

"Is this the Wind Dragon? Its Wind Dragon Pearl...well...if I guess correctly, it's in the belly of the Rat King."

Ning Qi held the knife and looked at the Plague Dragon Rat King coldly.

The opponent looked ferocious and seemed to be very powerful, but in essence, it was just a third-order BOSS-level monster, and Ning Qi really didn't take it for granted.

And there was a lot of space here, so he thought for a moment and let Xiao Zi out.

As soon as Xiao Zi appeared, the elite plague dragon rats who were waiting for an opportunity were instantly frightened. They were all monsters. They were frightened by Xiao Zi's aura and quickly retreated, hiding behind the Rat King.

The Plague Dragon Rat King bared his teeth and showed off to Xiao Zi and Ning Qi. How could Xiao Zi endure being humiliated by a monster two levels below her?

So it made a crisp cry and waved its wings to attack the Plague Dragon Rat King. The electric arcs on its body shot out directly. Upon seeing this, the Plague Dragon Rat King directly sprayed out a ball of green poisonous mist from its mouth and flapped its little purple wings.

The poisonous mist couldn't get close to it, and then Xiao Zi's purple lightning fighting energy was shot towards the Plague Dragon Rat King like thunder from the sky.

The Plague Dragon Rat King howled miserably and was knocked away by the purple lightning fighting spirit. After rolling on the ground a few times, it flew to the corner on the top of the cave and looked at the purple lightning bird with vigilant eyes.

Xiao Zi rushed toward it like lightning, grabbed the Plague Dragon Rat King's neck tightly with both claws, swooped down, and threw it heavily to the ground.

Ning Qi was cleaning up the group of third-level elite plague dragon rats at this time, which was equivalent to more than 200 dragon-slaying coins. How could he let it go? Seeing that Xiao Zi had more than enough here and had the plague dragon rat king in a mess, Ning Qi

He was relieved that in the time it took to drink some tea, there was no longer a living plague dragon rat near him.

In the huge cave, only the Plague Dragon Rat King was left. At this time, it was stepped on the ground by Xiao Zi, unable to move. The place Xiao Zi stepped on was its vital part, the neck, so the plague had some wisdom.

The Dragon Rat King did not dare to resist and could only make a squeaking cry for mercy.

Ning Qi walked up to the Plague Dragon Rat King with the dragon-slaying knife in hand, and swung the knife to chop off its head.

"Ding! Congratulations to the host for successfully killing the third-level BOSS plague dragon rat and gaining 3,000 experience points."

"Ding! Congratulations to the host for getting 100 Dragon Slaying Coins."

"Ding! Congratulations to the host for getting the gambling gift package, please open it within 24 hours."

Ning Qi had no plans to open the gambling gift package for the time being, but used the dragon-slaying knife to break open the belly of the Plague Dragon Rat King. Sure enough, he found a cyan dragon ball in its stomach!

As soon as his hand touched the Wind Dragon Pearl, a notification sound came from the system.

"Ding! Congratulations to the host for obtaining the mission item, the Wind Dragon Pearl. The mission timing starts now!"

Ning Qi put away the Wind Dragon Pearl. As for the gambling gift package, he did not plan to open it, because the Wind Dragon Pearl was found in the opponent's stomach and would probably be counted as one by the system. If he opened the gambling gift package

, if you choose to gamble, then there is a 80-90% chance that the Wind Dragon Pearl will disappear together, and the mission will naturally fail.

This is a small trap set by the system for Ning Qi. If Ning Qi didn't see the secret, he would have to beat his chest.

Next, Ning Qi spent a few days cleaning up the trapped fish in the cave. After confirming that there was no trace of the plague dragon rat, he walked out of the cave. He had not seen the sun for more than half a year, and Ning Qi was very satisfied.

I closed my eyes for several minutes to adjust before opening them.

Today, his dragon-slaying coins have increased from 4,500 before entering the cave to 58,000 today! It has increased more than ten times.

"Master Ning, I didn't expect us to meet again."

A familiar voice sounded.

Ning Qi discovered that there were two figures standing side by side outside the cave. He just didn't see them because his eyes were not used to the sunlight.

Looking up, he saw a guy he had missed for a long time!

It's Zhan Tai Qingxuan and Liu Suifeng.

At this moment, a trace of shock flashed across Zhan Tai Qingxuan's face, but he concealed it well the next moment: "Is this boy actually a peak fighting master?"
Chapter completed!
