19 Chapter 17. The Fruit of The Yin Spring Tree

 There was a piece of green crystal between the soil and the bones.

 This crystal wasn't a beast crystal but a dark green crystal. It was flat and octagonal. When Charles poured energy into it, it emitted a faint green light.

 However, Charles didn't find this crystal when he examined the skeleton of the Aqua crocodile.

 Where did it come from?

 Charles held his chin and carefully examined the crystal, but he couldn't see anything wrong with it.

 He could only decide to put the crystal in his pocket before making plans.

 "Frost Dragon Whelp, let's go."

 Charles said.

 He put away the crystal and was about to leave.

 Suddenly, he heard a few hurried "Goo Goo" sounds.

 He turned around and saw the frost Dragon Whelp running around in faraway circles. It was making anxious cries as if it was looking for something.

 What was it looking for?

 Charles was puzzled.

 This young Frost Dragon had lived with him for a long time, but he had never found any personal belongings of this guy.

 "Frost Dragon Whelp, what are you looking for? I'll go with you. "

 Charles walked to the front of the frost Dragon Whelp and asked in a low voice.

 However, the next second, he suddenly realized that something had disappeared.

 He was the one who disappeared!

 It was as if the frost Dragon didn't hear him. Its two eyes looked through Charles' body into the distance.

 Charles suddenly thought of the Aqua crocodile's sneak attack.

 He was a cautious person, and with the help of the analytical eye, he had checked the lake carefully before approaching it, confirming that no exotic beasts were lurking in the water.

 However, the hidden water-green crocodile suddenly appeared and attacked them.

 Charles guessed that it was this crystal that hid the body of the aquiline crocodile!

 Thinking of this, he stopped injecting energy into the crystal. The frost Dragon in front of him noticed him immediately and pounced on Charles, letting out a "Goo Goo" sound.

 "I see."

 Charles carefully kept the crystal in his inner pocket.

 This might be an incredible treasure.

 Charles decided to call it a hidden stone temporarily.

 ······

 The monster forest was not small. Charles took the frost Dragon Whelp and avoided the center of the monster forest. They went around in circles and killed their way to the Yin spring. A day and a night had already passed.

 On the way, Charles fought and walked, and the high-intensity battle lasted more than ten hours.

 The beasts in the middle of the monster forest were no longer of the first bloodline. They were all of the second bloodlines, and most of them were of the higher level.

 There were even two familiars with three lineages and green beast crystals.

 Under the eruption of Charles's bloodline, the exotic beasts were finally killed without mishaps.

 In total, Charles had gained 247 self-discipline points.

 And his body refining tier was also infinitely close to the second layer of the body refining tier. Only a breakthrough was left!

 Initially, he only needed 20 drops of blood essence of a second bloodline demonic beast to break through to the second layer of body refining tier, but Charles had absorbed 76 drops.

 Blood essence was converted into a permanent increase in the physique. Charles's second layer of body refining tier could be imagined as very different from ordinary people's second layer of body refining tier.

 Typically speaking, when one had just reached the first layer of body refining tier, they could already fuse their bloodlines with a familiar first tier. When he reached the third layer of body refining tier, he would be able to fuse his bloodline with a second Meridian ninth rank subdued beast.

 However, a Dragon's power was much more overbearing than an ordinary subdued beast's. An ordinary Dragon Tamer would have to cultivate to the fifth layer of the body refining tier before they could barely fuse their bloodlines with a second-tier Imperial Dragon.

 As such, Dragon Tamers usually could not perform bloodline fusion when their Dragon pets had reached a certain level.

 As for Charles, due to the system's strengthening, he could already fuse his bloodline with a first tier two lineage subdued beast at the second layer of body refinement and wasn't too far off from a Beastmaster.

 Perhaps, when the frost Dragon became an adult, Charles would still be able to fuse his bloodline with it. Then, his strength would be even more potent than an ordinary Dragon Tamer!

 Thinking of this, Charles looked at the Yin spring not far away. His eyes seemed more enthusiastic.

 "System, can I exchange for a growth potion now?"

 Charles asked.

 [Ding! [The host can open the system store at any time!]

 The system said.

 Charles immediately opened the system store and exchanged all the self-discipline points for growth potions.

 There were a total of 247 bottles of growth potion.

 The growth potion would be absorbed immediately after drinking it. This time, the frost Dragon Whelp didn't drink bottle by bottle. Instead, it picked up a pile of bottles and poured them into its mouth.

 "Many powerful demonic beasts are wandering around the Yin spring, so I must improve my strength as much as possible."

 Charles looked at the young Frost Dragon, who was eating heartily, and pondered.

 As the level of the frost Dragon Whelp increased, the number of growth potions became more and more insufficient. Initially, 20 bottles of growth potions could increase its level by one. Now, 247 bottles of growth potions only allowed it to rise from rank six to the peak of rank seven and almost to rank eight.

 Two hundred and forty-seven bottles!

 Charles sighed.

 Soon, the growth potion would be completely useless.

 His gaze then shifted to the following list of items in the system store.

 Unfortunately, this time was different from the last time. This product was completely locked, and he couldn't tell what it was.

 There was a line of small text on it, "unlock ten days of self-disciplined card-checking."

 In total, Charles had been self-disciplined for eight days. Soon, this product would be public.

 He put away the system panel.

 Charles looked at the Yin spring again.

 He led the young Frost Dragon and moved towards the spring.

 The yin spring wasn't big, about two meters in diameter, but it exuded a strange atmosphere.

 The spring water was gray and not clear. It was impossible to see what was inside.

 The ground around the yin spring was black, but it was not the rich black, but a muddy and ominous black. No weed was on this black ground, and the surrounding trees were all withered and dead. Their bodies were slender and looked like standing mummies from a distance.

 This place seemed to be a forbidden zone for life.

 However, it was not that simple.

 At the mouth of the yin spring, there was a dead tree with a mainly developed root system. Its black roots covered the ground like a spider web, and a few thick roots wriggled into the yin spring. No one knew where they reached.

 It was reasonable to say that this tree was the closest to the yin spring, and its body was the most withered and black as if it would break in the next second. It should be dead.

 However, a blood-red fruit was hanging on the tree branch.

 It was like a strange eye that opened in the darkness.

 Facing this most precious treasure, Charles didn't have the slightest desire. Instead, he felt very uncomfortable.

 A teacher from the Grinwood Academy had said that the yin spring fruit tree, which seemed to have withered on the surface, would produce a fruit every two months.

 It sounded like a mummy carrying a baby, weird and absurd.
