Fantasy: The system takes me to refine the magic formula

"System! Regarding monsters, I have read books. Everyone can only tame one in a lifetime. If I directly turn the egg in front of me into my monster, if I fancy other ones in the future, I won't be able to regain it again. !"

"No, no, this rule of yours is aimed at the people of this continent. Your soul comes from afar! Your spiritual power is unique! You can subdue any monster you want!"

"Hey! True or false?"

"Nature is real! The system will help you complete it!"

"Fuck! It's good to have the function of opening the golden finger! I'll try to sign a contract with the dark dragon inside this egg first!" Long Tian closed his eyes, slowly put his mind in the egg, and then tried to establish a connection!

Suddenly, Long Tian felt a burst of urgency, as if it was caused by the creatures in the egg. Long Tian could feel that the dark dragon in the egg wanted to go out, so he couldn't wait to sign a soul contract with Long Tian!

In this case, the dark dragon can only be loyal to Long Tian in the future, and will not betray!

"Success so easily?" Long Tian was a little surprised!
"Yes, host! Put this egg in the planting space, where the aura is the densest, it will help the dark dragon hatch, and in the future, as long as you summon it, the dark dragon will appear directly! Compared with those monsters The space is much more convenient!"

"Okay!" Long Tian put the dark dragon egg into the planting space. At the moment Long Tian put away the dark dragon egg, the dark elements around the abyss suddenly rushed into Long Tian's body crazily!

Long Tian felt that Jin Jiuye's original purple-gold light cast a gray light on the periphery!
And his Nascent Soul is also inexplicably absorbing the energy of the gray light, it seems that the aura of the dark system is even more beneficial to Long Tian!
"Well! You can go up! System, how long will it take for this dark dragon's egg to hatch?"

"In the system planting space, there is infinite spiritual nourishment, and it will hatch in a few years! If you are in a hurry, pour some of your previous spiritual spring on the dark dragon's egg, but I must remind you that the spiritual Quan only has those, if you don’t meet them, maybe you’re wasting them for nothing!”

"Uh... well, anyway, I'm not in a hurry to tame beasts! It's okay to wait, at worst, I'll go to the Warcraft Forest to find a few perfect tamed beasts! There are no other treasures here, so I'll go up there!"

"Well! Go up! There is nothing else nearby. The system cannot overuse the system's search capabilities in the secret realm, or it will be discovered by a few people outside who maintain the operation of the secret realm!"

"Know the system!"

After Long Tian replied, he stepped on the spiritual fan and quickly flew out of the abyss. At this moment, the abyss still had the dark aura left by the dark dragon, but it was not as strong as when Long Tian first came!

After Long Tian flew out of the abyss, he was worried that Dan Chenzi and others outside would doubt him, so he hurried to other places to try his luck, but Dan Chenzi, Bei Nian and the others saw Long Tian walking out of the abyss safe and sound, and their hearts were finally hanging. let go!

It's just that the original strong dark elements in the abyss have not dissipated, so Bei Nian and the others didn't think much about it!

Long Tian wandered in the secret realm again. No one knew how big the secret realm was and the disciples inside it, but Long Tian wandered in it for three days, and he didn't meet any of the disciples who entered the secret realm with him. And during these three days, except for the first day when Long Tian accidentally entered the site of the ancestor of Yihe under the control of the system, and then collected the eggs of the dark dragon, there was no other big chance, even if it was In the small-scale search of the system, only a few spiritual grasses were found!

But Long Tian is already satisfied to get the site of Yihe Patriarch!
After three days, Long Tian only felt his eyes blink, and he appeared on the square outside the Zongmen's main hall again!
Just after getting used to the surrounding environment, Hongying patted Long Tian's shoulder and said, "Master! These three days are really easy for Hongying to find!"

"Hehe Hongying, I didn't expect that we would disperse after entering the secret realm! What have you gained in these three days?"

"It's just that I accidentally found a magic weapon in a cave. It should be a low-level spiritual weapon. There are also two bottles of elixir, the highest grade is only the fourth grade. I found nothing else! What about you, master?"

"I found a master's ruins, and got some spiritual grass and pill furnace, but there is no method of cultivation. It seems that this master did not put his cultivation method in the secret realm!"

"Hehe, it's good to have spiritual herbs! I just don't know if we need to hand over the things we got in the secret realm to the sect!"

"The master master will talk about it later!"

"Uh-huh!"

After everyone in the main hall came out, Long Tian discovered that nearly one-eighth of the hundreds of people who entered the secret realm had died. This was still under the control of Dan Chenzi, otherwise there might be casualties The rate will be higher, and this is the secret realm inside Tianwu Academy, with such high casualties, it is conceivable that the danger level will be higher in the secret realm outside!
"The time for three days is up, all the disciples have come out! I think all the disciples have gained more or less in the secret realm, and Tianwu Academy has never collected any disciples' gains in the secret realm, unless it is cheat books and martial arts. Except for copying, you can keep everything else! This trip to the secret realm ends here! I hope everyone can cherish the gains from this secret realm! Cultivate seriously and strive to advance to the next stage as soon as possible!"

"Thank you, Sect Master!"

After Bei Nian finished speaking, he took Yuan Kai and others and disappeared in place, and Long Tian also flew back to Danchen Peak with Hong Ying!
At this moment, Dan Chenzi is already waiting for Longtian's return at the peak!

"Old man!! Are you waiting for us?"

"Yes! My good apprentice! Have you obtained the inheritance of the patriarch of Yihe?"

"No! There are some herbs in his place. I searched for his inheritance while digging, and later found his remains. There is only a ring, which contains his alchemy furnace and a few pills, and nothing else. Not even the manual for alchemy, nor the martial arts for cultivation!"

"Hey! It's a pity! It is said that the patriarch of Yihe has perfect alchemy skills, and many top-level pills of my Tianwu Academy are refined and passed down by him!"

"Old man, Tianwu Academy was originally called Tianwu Sect?"
