"What's the use of this thing?"

In the bedroom, Du Mu stared intently at the primordial pyroxene in his hand, with a faint doubt on his face.

According to his previous speculation, it is very likely that the primordial pyroxene is related to the production of pyroxene, which is also proved by the fact that Kuroye even risked a sneak attack on a military base for the sake of the primordial pyroxene.

It's just speculation and speculation, how the origin pyroxene produces pyroxene, he has no way of knowing.

Recalling the crystallization point he saw in the underground cave not long ago, Du Mu's eyes flashed with a thoughtful light.

Jumping off the bed, Du Mu pushed open the bedroom door and came to the living room.

The living room was still in the same state as when he first entered the dream realm, after all, he had hardly spent much time here, and he only passed by every time he had to leave the apartment, and he was probably in the bedroom when he was cultivating.

Looking around, Du Mu quickly picked a vacant space in the corner of the living room and gently placed the primordial pyroxene on the ground.

Standing in place and staring for a moment, seeing that the Yuan Chu Pyroxene had never reacted, Du Mu came back to his senses and patted his head with a dumb smile.

"I'm so anxious, no matter how I say it, I won't react so quickly. ”

Shaking his head, he was about to turn around and leave the apartment, when suddenly his steps paused, as if he remembered something, and his expression moved.

"Speaking of which, can Xiao Jiu take pyroxene to improve his strength?"

At present, the improvement of strength pyroxene, physique pyroxene and agility pyroxene has reached saturation, and no matter how much he takes, it will not have an enhanced effect, but there are still a lot of these three pyroxenes left in his body.

"Sister's words shouldn't be needed. Du Mu touched his chin and groaned.

Even he can get nearly two hundred pyroxenes, go deep into the inner area to explore, and Du Shuang, who has been exploring for a longer time, will only get more pyroxene than him.

Thinking of this, Du Mu's heart moved, and a large amount of gray mist instantly appeared on the surface of his body, surging and condensing Xiao Jiu's figure.

After nearly ten days, he finally came out of the gray dream again, but Xiao Jiu's expression did not change, and his face was still expressionless.

Du Mu took out a power pyroxene stone and handed it to Xiao Jiu: "Eat it." ”

Hearing this, Xiao Jiu immediately stepped forward, bowed his head slightly, opened his small mouth and took the power pyroxene and the tip of Du Mu's index finger into his mouth together, and immediately straightened up his body and swallowed the pyroxene with a grunt.

“......”

Du Mu was stunned, he just wanted Xiao Jiu to reach out and take it, but he didn't want to feed her.

Du Mu, who was inexplicably teased, scratched his head and used the combat power detector on Xiao Jiu, and found that the latter's combat power increased by 2 points.

"It's good, it works!"

Overjoyed, he simply left only six of the three kinds of pyroxene in the dimensional house, namely strength, physique, and agility, and took out all the rest, and put them on the coffee table in the living room, letting Xiao Jiu sit there and absorb them slowly.

After more than ten minutes, Xiao Jiu finally finished absorbing the pyroxene, and his combat power soared to 723, an increase of more than 100 points.

"It's a pity, 723 is still a bit low. Du Mu groaned secretly, "I don't know if the real heaven and earth treasure will be effective for Xiao Jiu?"

"Try it another day!"

With a slight movement of his mind, he took Xiao Jiu back, Du Mu took out the Yu Yu, and prepared to continue exploring the corridor.

......

The next night.

After finishing his day's cultivation as always, Du Mu received a text message from Luo Shen, inviting him to go to a place.

"The exploration of the ruins is over, and it's time to take over the task. ”

Reunited with Luo Shen, the two left the academy, first found a remote corner to change into black robes and masks, and then came to the back door of a bar, located in a dark alleyway.

Unlike the quiet retro-style bar when I last met Xu Yun, this one is quite lively.

Standing in the shadow of the alley, Du Mu looked over from afar, and could see that under the marquee, many men and women hugging and laughing with each other, their movements were intimate, and there were burly guards guarding the door.

"This bar is one of the strongholds of the annual ring in the capital, and is mainly responsible for the handover of tasks, the collection of mission rewards, and the merit transaction. "Of course, the bar is just a cover, and the real place where the task is handed over is under the bar, and the entrance is here. ”

He pointed to a rusty iron door not far away.

The iron door has no handles, and is bare with only an inconspicuous keyhole and cat's eye. Next to it are mountains of black garbage bags.

The air was filled with an unpleasant and strange smell, and Du Mu frowned slightly, a little speechless.

"Can't you choose a better place as a stronghold? ”

Luo Shen shrugged his shoulders and said, "I don't know why I chose here, but I have to say that the concealment is really strong." ”

With that, he stepped forward and knocked on the iron door, a total of three times, and then took out a card from the black robe and placed it in front of the cat's eyes at a distance of about twenty centimeters.

A moment later, there was a click of unlocking from inside the iron door, followed by a creak, and the door slowly pushed open.

A sturdy man wearing a vest and tattoos on his arms leaned out, glanced at the two of them, and then took the card in Luo Shen's hand and carefully studied it for a few seconds, the vigilance on his face slowly dissipated, and then showed a respectful look, turned sideways to make way for the road leading to the door, bowed down and said, "Two of you, please come in!"

Luo Shen bowed his head lightly and gestured to Du Mu, and the two quickly flashed into the door.

Behind the door was a hallway, with only a faint flickering old metal lamp in the corner, and the light was very dim.

Led by Luo Shen, the two passed through the corridor without saying a word.

On both sides of the corridor were rooms with closed doors, Du Mu listened intently, and did not hear the slightest movement, but he keenly felt a faint sense of oppression from behind these doors.

“...... The guards of this stronghold? Du Mu secretly guessed.

From time to time along the way, people in the same dress came up to them and passed by them, and both sides tacitly did not communicate.

At the end of the hallway was a spiraling staircase, and after walking the steps, the two finally entered a bright and spacious hall.

The lobby has also been transformed into a bar-like design, and there is even a bar counter, where many people are already waiting, dressed in different costumes, but without exception, they all hide their faces, and they sit together in twos and threes, talking in low voices.

The appearance of Du Mu and Luo Shen did not attract everyone's attention, and many people raised their heads slightly, as if they glanced at the two of them, and then withdrew their gaze and continued to talk.

"Come over here. Luo Shen walked to the bar and greeted a young girl in a ponytail, wearing a white shirt, a black vest and a short skirt.

"Little Red Phosphorus, come here. After that, he turned his head and explained in a low voice to Du Mu, "Red phosphorus is one of the 'waiters' in this stronghold, she has been working here for a short time, many businesses are clear, and her character is also good, you can ask her for help when you come to hand over tasks or transactions in the future." ”

"Ah, Mr. Light. "The girl named 'Red Phosphorus' recognized Luo Shen's voice for the first time, and walked over with a smile, "Are you here to take over the task today?"

Feeling Du Mu's strange gaze, Luo Shen coughed and said in a low voice: "Didn't I say it, it's best not to reveal your true identity, including your name, so most of the people who come here to do business use code names, and my code name is 'Child of Light'." ”

Du Mu was stunned.

"You also have to give yourself a code name so that it's easier to do things. ”

After saying this, Luo Shen looked at the red phosphorus and pointed at Du Mudao: "Let me introduce, this is a new member who recently joined the organization, and today he is here to hand over the assessment task, and he has already reported to the above, and the information required for the task content has also been uploaded, you can check the records to know." ”

As early as on the train on the way back, Du Mu had already sorted out the relevant information of the ruins and handed it over to Luo Shen to help hand it over.

"Also, it's an item that the mission requires. Du Mu took out six pyroxene and handed them to the red phosphorus.

"Understood!" Red Phosphorus took the pyroxene, made an OK gesture, walked quickly into a small door behind the bar, and returned after a while, looking at Du Mu with a smile on his face.

"Welcome to the Rings, what do I want to call you?"

"Nightmare!"

Du Mu said the code name that he had already thought of.

"Mr. Nightmare, right?" Red Phosphorus checked again, then entered the secret door behind him, and this time only waited for more than ten seconds before coming out, with an extra card in his hand.

Coming to Du Mu, Red Phosphorus smiled and handed him the card.

"This is the identity certificate of the annual ring member, with your exclusive identity number and unique chip on it, which has been bound to the code name of Nightmare, whether it is entering the stronghold, handing over tasks or trading merit values in the future, you need to show your identity card, so please keep it properly, don't lose it!"

"If you reissue the identity card, the merit points required are not small, and the authentication process is also very troublesome!"

"I see, thank you!"

After taking the card, Du Mu took a closer look.

The cards aren't paper, they're a bit of metal, and they feel cold to the touch in your hand.

The back of it is painted with starry sky stripes, and the front is a circle from the inside out, from small to large, like the concentric rings on the cross-section of some trees, which just reflects the name 'growth rings'.

"In addition, the 10 merit points of the reward for this assessment task have been hit under your identity number, and you can consume the merit at any time to exchange it for cultivation resources, or services that other organizations can provide. ”

Du Mu pondered for a while and asked, "What cultivation resources can be exchanged?"

Hearing this, Red Phosphorus smiled slightly, stretched out his finger and pointed to a whole row of self-service terminals next to the bar, "The seven self-service terminals there can query the exchange list, and more than ninety percent of the exchange items can be found on it, if you need to exchange special items, you can consult me, and after I report to the above, I will give the merit value that the exchange is needed." ”

Du Mu nodded slowly.

"Let's go, I'll take you over and have a look. ”

Luo Shen patted him on the shoulder, turned around and walked towards the self-service terminal.
