If I had known I wouldn't have saved you!

After a long time, the black dragon still didn't come out, so Lin Shiyi simply lay down on the shore, closed his eyes and took a nap.

Not long after, undercurrents surged in the swamp again, and a ball of foam emerged from the black muddy water and slowly swam to the shore.

"Roar!"

Suddenly, a roar was heard, and the black dragon, covered in mud, crawled out. Its huge body pounced towards Lin Shiyi like a leap over the dragon gate!

"Waiting for you!"

He dodged to the side, and the formation in front of him activated automatically. A flash of light passed by, and the black dragon was pulled into the formation!

Although this monster was a black dragon with a single horn, it had no limbs. After being pulled ashore, it rolled clumsily on the sand, staring at Lin Shiyi with its pair of lantern-sized eyes.

"Roar!"

It opened its bloody mouth and pounced towards Lin Shiyi regardless of anything. The large formation was almost broken apart by it.

Fortunately, the formation had been filled with energy earlier. At this moment, the formation was filled with flames, lightning and thunder. Under the fire and thunder, the black dragon struggled painfully, and its huge body raised the surrounding sand all over the sky.

Afterwards, the Liuxian Formation also exerted its power, and arrows made of spiritual energy pierced the black dragon fiercely. After piercing its body, the arrows disappeared, leaving behind a small hole from which spiritual energy continued to overflow.

Seeing its body getting smaller and smaller, the black dragon reacted and hit the formation in front of it with all its might. Finally, after its powerful attack, it created a huge gap in the formation. It coiled its body, jumped with all its might, and jumped out of the formation. However, before it could do anything, a formation in another direction pulled it in again.

For a while, there was constant fire and thunder, and the evil beast howled miserably.

Lin Shiyi was eating some melon seeds on the side. Seeing that there was a lot of movement in the formation, he threw a thunderbolt pill into it. With a loud bang, the beast became silent.

When the smoke cleared, the black dragon was only three feet in size, and its cultivation had dropped to the Qi Refining Stage. There was not a single piece of good flesh on its body. A burnt smell wafted over, and Lin Shiyi drooled at the smell.

"Done. Looks like I overestimated this evil creature and wasted so many pills."

Lin Shiyi stepped forward and first used the soul-binding technique to subdue the black dragon before he withdrew from the formation.

Holding the black dragon in his palm, Lin Shiyi stood up and looked at the fallen white flower on the side. He took out the medicinal material illustration and compared it. The flower looked exactly like the immortal lotus.

Lin Shiyi was so happy that he collected all the dozens of white flowers without thinking twice. Then, he used his spiritual energy to control the black dragon in his hand in the air.

The black dragon struggled, but couldn't break free because of its weakened strength. At this time, it looked at Lin Shiyi hatefully, its mouth opening and closing.

"Despicable human monk! Let me go right now!"

Lin Shiyi's eyes widened in surprise and he said with a smile, "You can talk? It seems that you have awakened your spiritual wisdom. Why do you want to cause trouble to others? You even want to eat me, the immortal. Do you know how serious your sin is?"

The black dragon struggled and said, "Roar! I don't know what you are talking about. I grew up here and was able to roam freely in the Twelve Lakes. Their people always put food on the shore. It has been like this for so many years. They fed it to me on purpose!"

Lin Shiyi took out a white flower and asked, "Do you know what this is? And why is it growing on your body?"

The black dragon said angrily: "How should I know? Every time I travel through the Twelve Lakes, these things will cling to me. It's so annoying!"

Lin Shiyi always felt that something was wrong. The black dragon spoke like a child, very innocent. It seemed that it was not really a monster, but just survived by instinct. However, without anyone to control it, it was inevitable that it would hurt the creatures approaching the lake shore.

"I see that you don't have enough to eat every day here. How about you follow me? Apart from anything else, with a master, other monks won't deal with you, and I can also help you improve your strength. How about it?"

Lin Shiyi negotiated with him.

In fact, he was thinking about the Feilong City. How cool would it be to be able to ride a black dragon through the city like his great-grandmaster?

Unexpectedly, the black dragon said with disdain: "Just you? A useless cultivator in the early stage of foundation building? How can you trample on the dignity of my dragon clan at will?"

"You don't believe it, right? How about we make a bet? If I can help you break through the realm, how about you just recognize me as your master?" Lin Shiyi said with a smile.

The black dragon said disdainfully: "Okay, if you can do it, not only will I recognize you as my master, I will also accept you riding me every day!"

"Okay, but I need to cast a spell on you first. Otherwise, what if you become stronger and regret wanting to eat me?"

As he spoke, Lin Shiyi cast a puppet curse on the black dragon. This was a magical curse that could control the opponent's life and death. Unless the caster of the curse personally broke the curse, it would be impossible for the opponent to resist.

The black dragon's life was already in Lin Shiyi's hands. When it heard that it was going to be cursed, it just snorted but didn't say much.

As Lin Shiyi finished casting the spell, he took out many Dahuan Dan from his storage bag.

"Open your mouth."

He said while holding the pill.

The black dragon opened its mouth obediently, and Lin Shiyi threw a handful of pills into its bloody mouth.

After chewing for a while, it swallowed the pill in one gulp. After the effect of the medicine took effect, its body gradually grew bigger and returned to its original size.

"Not bad. Hey, do you have any more? It's delicious."

Having tasted the sweetness, Black Dragon immediately started drooling and looked at Lin Shiyi expectantly.

"You can eat as much as you want."

Lin Shiyi chuckled.

Then, he took out twenty Dust-Repellent Pills at once and threw them to the Black Dragon. The Black Dragon took all of them in his mouth and swallowed all twenty Dust-Repellent Pills like candy beans.

In a short while, its body grew a lot bigger, and four short claws grew on its abdomen, which looked weird, but its strength had indeed been upgraded to a level 5 demon beast. After all, it was a demon beast, and it took three times more dust-avoiding pills than a human cultivator to upgrade, but if it could harvest a level 5 demon beast, it would be worth spending so much pills.

"I never thought... a cultivator in the initial stage of foundation building would have so many miraculous elixirs... I underestimated you!"

The black dragon flew over, coiled its huge body into a pile, and surrounded Lin Shiyi in the center.

Lin Shiyi looked at it warily and said, "Don't mess around. With the puppet technique, I can take your life at any time."

Unexpectedly, the black dragon said angrily: "What kind of dragon do you think I am? My dragon clan is a man of his word. Since I have promised you, I will not go back on my word! You are qualified to be my master!"

Lin Shiyi breathed a sigh of relief, and then said, "Well, I hope you won't break your promise. Let's acknowledge you as our master right away."

As he spoke, he cut his finger, wrapped up a drop of blood with a secret method, and sent it to the black dragon's mouth.

"After you eat it, you and I will be connected by blood. From now on, as long as I exist, you will exist too. If I die... you will die too."

Lin Shiyi said seriously.

Without saying anything, the black dragon swallowed the blood clot in one gulp, then he knelt in front of Lin Shiyi and said, "Master, from now on, I will only listen to you!"

Seeing this, Lin Shiyi finally relaxed. He collapsed to the ground and said, "It's finally solved. I was so nervous that I almost died."

The black dragon didn't care about anything else and jumped into the swamp, splashing around happily.

Lin Shiyi was covered in mud. He immediately gave the beast a cold look and started to clean himself up.

At this time, a group of people came from not far away.
