The Witcher: Son of the Planes.

Colin did not wait for the auction to end before leaving the auction house with Beta. When settling the bill, because he did not have enough wizard coins, Colin gave the other party more than a dozen Warcraft heart cores.

Although 10,000 wizard coins can be exchanged for one level one Warcraft heart core (magic core for short), in reality, more magic cores can often be exchanged. But Colin was in a hurry and had no time to go outside to exchange wizard coins, so he had to lose some magic cores.

Back at the inn, Beta and the others were curious about Colin's auction. After asking, they found out that Colin, as a human, had been feeling a little weak in recent years, so he had been working hard to improve his physical attributes by fusing the blood of dragon monsters.

"Haha, you should have said it earlier. I might as well ask Chief Gamorrell for some Komodo blood. If you really want it, the heart of an old Komodo monster is not a big problem." Beta said.

"Yes, Colin, you know, we orcs have always been strong in this aspect. Just a little bit of it will be enough for you to use." Kobe also said with a wink.

"I & you two, I knew I shouldn't have told you." Colin was speechless.

"Forget it. I was willful this time and interrupted your auction process. I should have stayed a little longer."

"It's nothing. We've spent a lot of money anyway, and we probably won't be able to afford the next items. What do you think of the next step?" Beta asked.

"Being able to obtain this dragon heart, I feel that this trip underground is really the right one. I have gained a lot and dare not ask for anything else. I still understand the principle of too much is as bad as too little. But it depends on you. I can accompany you wherever you go. Anyway, I don't have anything else to do."

Beta and Kobe looked at each other, and both felt that nothing was wrong.

"How about we go back to New Trey," Kobe suggested.

"Okay, then I'll borrow your precious land for a while. The environment here is not suitable for experiments. Let's go back to your New Terre so that I can extract the blood of the magic dragon."

Colin and his two companions decided to return, and it took them more than a month to get back to New Tre.

As soon as he returned to New Tre City, Colin entered a secret room prepared for him by Beta and began to extract the blood of the dragon without sleep.

Because the dragon's heart still had a lot of activity, Colin did not extract it violently. Instead, he slowly extracted a little bit of the dragon's blood every day until the activity continued to decrease and was almost lost, then he stopped.

"You can't extract any more blood. If you do, the heart will completely lose its vitality. Colin looked at the results of the past half month in front of him. Eight bottles of underground dragon blood should be able to improve his physical fitness a lot.

Looking at the dragon's heart again, let's give it to Charles. It should also help him in his promotion. After all, Charles is also a sub-dragon beast, and the orthodox dragon bloodline will definitely be of great help to him."

After deciding on the purpose, Colin left the secret room, summoned Charles, and threw the dragon heart to him.

"Oh, my dear master, I knew you were the best to me. Is this thing for me?" Although Charles didn't know what species the heart belonged to, the pure dragon aura on the heart could not deceive him. This was at least a first-level dragon creature.

"You, man, if it's useful to you, then I am your master. Just call me Colin. Never mind. This is the heart of an adult underground dragon. It is said to be a level 2 creature. Enjoy it. I have been promoted for many years, but you still can't. You are too useless. I hope this is useful to you. Well, you stay here these days. I look forward to your subsequent performance."

After saying that, Colin ignored Charles and entered the secret room again. He also needed to make a breakthrough and improve some attributes.

"Earth Star, check my physical attributes at any time. I need a detailed data set." Colin ordered.

"Okay, master, please leave the data to me." Dixing replied mechanically.

Colin meditated first to restore his mental strength to full value, and slowly adjusted his mentality. Only after he was completely calm did he pick up a bottle of dragon blood and drink it.

"Current attributes: Strength 18, Agility 17, Constitution 18, Mental Strength 38.6, Luck 5; Human bloodline 72%, Subdragon bloodline 5%, Fire element bloodline 23%; Fire attribute affinity 70%, Earth attribute affinity 20%, Light attribute affinity 1%, Dark attribute affinity 1%, Space attribute affinity 3%, Unknown attribute 5%"

……

"Strength increased to 20 points, agility increased to 18 points, physique increased to 20 points, mental strength increased to 38.8 points, human blood increased to 74.5%, magic dragon blood increased to 1.5% (including 0.5% of the sub-dragon blood fused into the magic dragon blood), fire element blood increased to 24%, fire attribute affinity increased to 72%, earth attribute affinity increased to 18%, light attribute affinity increased to 0.5%, and dark attribute affinity increased to 1.5%. The rest of the attributes remain unchanged." said the Earth Star Machinery.

Colin compared the data. It seems that the effect of the dragon's blood is very significant. His physique has increased by two points, and even his strength and agility attributes have increased. Judging from the data, Colin's physical fitness has reached the minimum standard of a first-level knight. However, because he does not have a suitable breathing method, Colin has already given up the path of a knight.

Judging from the composition ratio of blood and elemental affinity, the influence of the dragon bloodline is indeed more towards the dark attribute. The improvement of the fire element has given Colin a small surprise. Relatively speaking, there should be a bonus effect when Colin casts fire witchcraft.

Try another bottle, Colin thought.

Soon, Colin drank another bottle of dragon blood.

……

"Strength 21, Agility 18.5, Constitution 21, Mental Strength 38.9, Demon Dragon Bloodline 2%, Fire Attribute Affinity 73%, Dark Attribute Affinity 1.75%, the rest of the attributes remain unchanged, but the corresponding human bloodline and earth attribute affinity have dropped again by a certain percentage."

Colin compared the effect with the second time, which was equivalent to being halved. Colin knew that the influence of the dragon's bloodline on him was basically like this, but with the idea of ​​improving as much as possible, Colin drank the third bottle and prepared to keep the remaining five bottles for backup.

The effect of the third bottle was not as great on Colin as the first and second times. His body just felt slightly warm and then it was over.

It took Colin more than an hour to consume three bottles of dragon blood. The latest data detected by Earth Star was:

"Colin, male, 71 years old, strength 21.4, agility 18.7, constitution 21.5, mental strength 38.9, luck 5; human blood 73.2%, magic dragon blood 2.3%, fire element blood 24.5%; fire attribute affinity 73.5%, earth attribute affinity 16.2%, light attribute affinity 0.4%, dark attribute affinity 1.9%, space attribute affinity 3%, unknown attribute 5%"

Seeing the latest attributes, especially the physical attributes, which had surpassed those of the newly promoted first-level knight, Colin almost jumped up with joy. It had been so many years since he felt so happy.

He was very satisfied with the gains from this underground trip. Physical fitness was not only reflected in that aspect, but also in the speed of recovery after injury and the bonus of one's own resistance.

This time the value reached 21.5, and Colin felt that the 120 million was well worth it.

"Maybe at some point, I can try to disguise myself as a knight?" Colin thought with evil humor.
