Sili School Department, Luoyang City, in a school field.

When Lu Haikong saw those two drawings, he couldn't help but raise the corners of his mouth, the attributes of these two drawings were easy to see, they should be used to deal with the [Extraterritorial Demon] big killing weapon.

However, Lu Haikong was not too happy, after all, the current two copies are just drawings, and they are still far from the finished product, and the real effect is not clear, and even if the effect is very gratifying, it is also necessary to consider issues such as manufacturing difficulty and manufacturing cost.

If the cost is too high, it will be difficult to do it on the land, sea and air side, after all, this guy has been working on a lot of money-consuming projects at the same time recently.

After Lu Haikong took a few looks, he directly handed over the two drawings to Xu Shu and asked him to send them back to Yanhuang City, and immediately asked the master blacksmith carpenters of the [Carpenter Battalion] and the [Blacksmith Battalion] to devote themselves to research, and asked them to send him the data as soon as possible.

After processing these two drawings, Lu Haikong's treasure chest this time is basically coming to an end, and then Lu Haikong only has one mythical prop left, and once he collects that thing, opening the treasure chest this time will be completely over.

According to Lu Haikong's consistent urine nature, this guy has always put the best things at the end, and this time the [Mythical Level Props] that he put at the end are obviously what he is looking forward to the most, and when this guy is ready to receive the final reward, the whole person is a lot more energetic.

I don't know if it's Lu Haikong's experienced intuition is amazing, what this guy keeps to the end has always been the best of every harvest, and this time it's the same, but what Lu Haikong didn't expect was that the surprise to him this time was a little big.

Just when Lu Haikong chose to receive the last [Mythical Grade Item], an object that Lu Haikong was very familiar with appeared in front of him.

It is a mysterious guqin more than one meter long, with a simple and mysterious style and unknown material.

Lu Haikong was stunned when he saw this piano, and then a smile appeared on the corner of his mouth: "I didn't expect this thing to come out in the end, but it's not bad, plus this mysterious guqin in my hand, there are 6 copies, as long as there is one more one, I can make up seven copies." ”

The origin of the mysterious guqin is mysterious, and the power contained in it is also quite terrifying, if you really want to count it, this thing may be the most grounded artifact in the land, sea and air camp.

Lu Haikong's [Renhuang Ding] dared to say that it would be devoured in the face of [Yuwang Ding], a humane artifact that has been passed down through the ages, but in the face of the mysterious guqin, [Renhuang Ding] has obvious fear, and from this point it can be rudely concluded that the origin of the [mysterious guqin] is even greater than that of [Yuwang Ding]!

However, although the [Mysterious Guqin] is mysterious, this thing can never be used by Lu Haikong, and it is clear that the [Mysterious Guqin] is no longer exclusive to Lu Haikong now, but Lu Haikong still can't grasp things, and he doesn't even know the real name of that [Mysterious Guqin].

For this situation, Lu Haikong can only give himself an explanation that the [Mysterious Guqin] has not been collected, if the remaining two copies are also collected, Lu Haikong may be able to get the [Mysterious Guqin] to recognize the owner.

For Lu Haikong's own explanation to himself, Lu Haikong had always believed it before today, but today, after Lu Haikong got the sixth [Mysterious Guqin], Lu Haikong found that this explanation was a little untenable, because just after that [Mysterious Guqin] appeared, an accident appeared!

The [Mysterious Guqin] appeared in front of Lu Haikong, and before Lu Haikong could reach out to catch the [Mysterious Guqin], it moved as if it was alive, swimming in the air like a swimming fish in the direction of the palace.

"What's the situation? Is it the Mystic Guqin that is summoning it? Lu Haikong was stunned for a moment, and then although he immediately gave himself an answer, he still subconsciously followed, anyway, his current treasure chest was basically opened.

Lu Haikong rose into the sky, and kept following closely behind the [Mysterious Guqin], and in a few minutes, the [Mysterious Guqin] and Lu Haikong returned to the palace one after another.

Originally, Lu Haikong's face was light and cloudy all the way over, but as soon as he entered the palace, Lu Haikong's face changed, because he found that the [Mysterious Guqin] was not in the right direction, and he did not fly to the [Zhentian Palace] where the artifact was placed as he expected, but thought about the third princess and the dormitory.

Lu Haikong couldn't sit still now, he didn't think that this [Mysterious Guqin] could do anything to the three princesses, after all, the three princesses were also the sword bearers of the [Chixiao Sword], and the strength of the three princesses would not be too bad even if they were not as good as Lu Haikong, and a mere [Mysterious Guqin] could not pose any threat to the three princesses, but there were two little guys in the third princess's bedroom.

Lu Haikong didn't know what this [Mysterious Guqin] wanted to do, and it would be very bad if he hurt those two little guys, so after Lu Haikong found that the [Mysterious Guqin] was in the wrong direction, he immediately started to stop the [Mysterious Guqin].

However, what shocked Lu Haikong was that the power of the [Mysterious Guqin] that erupted at this time was far beyond his imagination.

Lu Haikong broke out continuously, and it was the Dao Fa's [Innate One Qi Grabator] and the explosive force stepped forward to grab it, but at the same time as Lu Haikong shot, a thin protective shield appeared outside the [Mysterious Guqin], just such a thin layer of existence blocked several rounds of attacks by Lu, Hai and Kong.

"Damn, it's against you!"

Seeing this situation, Lu Haikong was completely angry, and after shouting angrily, the purple-gold light on this guy's body surged wildly, and under the shroud of purple-gold light, Lu Haikong at this moment was like a purple-gold god of war.

In the case of the full outbreak of "Purple Qi Ascending Dragon Duel", Lu Haikong's figure flashed, and the extremely domineering momentum on his body smashed on the [Mysterious Guqin] like a mountain, and at the same time, he reached out and grabbed the [Mysterious Guqin] firmly in his hand in the flashes of purple-gold light, and forcibly let this [Mysterious Guqin] stop outside the third princess's dormitory.

"Finally stopped this thing!" Lu Haikong finally breathed a sigh of relief.

However, just when Lu Haikong put his heart down, the third princess's bedroom was suddenly opened, and two cute little Loli popped out of their heads.

"Two-legged beast, what are you doing?"

"Not good!"

At the moment when the door was opened, Lu Haikong's face changed, but before he could react, the [Mysterious Guqin] in his hand suddenly flashed, and then the [Mysterious Guqin] suddenly shattered, and then the shattered [Mysterious Guqin] turned into a streamer and poured into the door opened by the two Loli and rushed into the dormitory.

"Yue'er, hurry, stop it!"

The three princesses in the dormitory also woke up from a dream, and when they realized that the target of that streamer was their daughter, a momentum that was far more violent than land, sea and air surged, and the [Chixiao Sword] in the hands of the three princesses appeared out of thin air, and they did not hesitate to slash towards that streamer.

However, the third princess did not hesitate here, but the [Chixiao Sword] in her hand hesitated, not only did she not cut it down, but also transmitted a message to the third princess at this time.

And at the same time as the [Chixiao Sword] transmitted information to the third princess, that streamer had already fallen on one of the little guys on the bed......
