The one who opened the door was an old man with gray hair, and when he saw Merlin, his face showed a puzzled look, and he asked softly, "Who are you looking for?"

"Excuse me, does Eru live here? I'm a friend of Mr. Eru's named Leo, and I'm sure Mr. Eru will know. ”

Merlin identified himself, and the strange old man looked Merlin up and down, and then said, "Please wait, I'll go and ask Lord Eru." ”

This Eru seems to have a very high status, after all, although this ancient castle is relatively old, it is naturally unusual to have such a huge castle in the Holy Dragon City, where every inch of land is valuable.

After a while, a loud laugh came from inside the castle: "Haha, is it Young Master Leo? ”

The door opened, and Eru had changed into a noble dress at this time, exuding a noble and elegant temperament, which is not something that ordinary nobles can do, even Count Steinwin does not have such a temperament, which requires hundreds of years of precipitation from a noble family.

Eru's identity is mysterious, when he was in Boulder City, he only opened a fossil exhibition hall, which is really a bit strange, Eru is thoughtful, but he is definitely not some aristocratic gentleman.

"Curator Eru, we're meeting again!"

Although many thoughts crossed Merlin's mind, at the moment, he seemed very calm.

"Master Leo, let's go in and talk. ”

After Eru invited Merlin into the living room, he kept looking Merlin up and down, and then his eyes flashed with a strange light, and he whispered, "I got the news not long ago. Marshal Kelly was defeated by the Black Bats and the Barbarian Horde. Boulder City also fell into the hands of the Black Bats. I was still worried about Young Master Leo's situation, but I didn't expect that Young Master Leo had already arrived in Holy Dragon City. I don't know if Master Leo came to me this time, but what's the matter?"

Eru was vaguely expectant, even urgent, he had been paying attention to Merlin's news, after all, Merlin was a rare parasite, and he had successfully parasitized it himself. Although he had already obtained the number jù before, as a study parasite, such a number of jù was far from enough.

Merlin pondered for a while, and suddenly stood up, since he wanted to obtain the formula and resources of the nutrient pool from Eru, then sooner or later he would be discovered by Eru that he had reached the third form of beastification, it was better to take the initiative to tell Eru, and it would make Eru even more tempted.

After all, a parasite of the first form of beast and the third form of beast cannot be compared in any way. Many people start with parasitism that succeeds. But as the beast became more and more powerful, the will of the giant beast became stronger and stronger, and finally reached the second or third form and was eaten by the will of the giant beast and died.

And now Merlin is still standing in the hall in good health, and that alone can make Eru very tempted.

"Huh".

Merlin quickly began to become a beast, his aristocratic clothes were torn, and his body grew rapidly, and finally he was more than two meters tall, and except for the upper body and head, the rest of the place was covered with a layer of dense black hair, which had turned into the body of a giant wolf.

"The third form of beasthood?"

Eru looked shocked and almost cried out, you know, it was only a few months since he left Boulder City, Merlin was still a parasite who could be dangerous at any time, but he actually reached the third form of beast, such a speed can be called terrifying.

"Yes, the third form of beasthood!"

Merlin recovered, but he was naked, which was a little awkward. With a wave of his hand, Eru brought a set of clothes for Merlin to put on.

After a long time, Eru slowly spoke, "You got the nutrient pool formula?"

If the parasite wants to improve his strength, he can only rely on the nutrient pool, so Eru immediately thought of the key to the matter, Merlin already has a nutrient pool formula.

"That's right, Curator Eru, don't forget that my father is a powerhouse at the peak of the fourth form of beastification! It's not easy to get some nutrient pool formulas, but it's not too difficult. ”

Eru nodded, even if he was confident in his own strength, he was still very jealous of Merlin's father, Count Stanwin, the dire crocodile bloodline was a mid-level bloodline, and if he could train it to the peak of the fourth form of beasthood, he could be regarded as a strong person anywhere.

"Now that you have the Nutrient Pool formula, why are you coming to me today?"

Eru originally thought that Merlin came for the nutrient pool formula, after all, without the nutrient pool, it would be difficult for the parasite to improve his strength, but Eru was a little uncertain now.

Merlin didn't hide it, and said directly: "Who would have too many nutrient pool formulas? What's more, the nutrient pool formulas in my hands will always have no effect, and when the time comes, Mr. Eru's nutrient pool formulas will be precious." What's more, the materials for preparing the nutrient pool are not affordable for ordinary people. ”

Eru was stunned for a moment, then laughed too.

"Haha, yes, yes, who would have too many nutrient pool formulas? Moreover, now that the Holy Dragon Empire is in chaos everywhere, the supply of some commercial houses has also been affected, so the materials for some nutrient pool formulas are very expensive. Moreover, Young Master Leo, you should also know by now that if this parasite wants to improve his strength, the materials of the nutrient pool alone are far beyond the capacity of ordinary nobles. ”

Eru had already understood Merlin's intention, in fact, it was for the nutrient pool formula, but more importantly, Merlin had no way to get expensive nutrient pool recipe materials.

Eru also has a deep understanding of the high cost of materials, but fortunately he has a special method, the material problem has already been solved, and there is a reason why he is committed to studying parasites.

Although Eru is very mysterious, Merlin can also roughly feel that Eru is also a strong man with the blood of a giant beast, and his strength should not be inferior to Count Stanwin, I am afraid that he has also reached the fourth form of beast.

However, this may also be Eru's limit, relying on the bloodline of the giant beast, if he wants to go further, break through the only care, and achieve full beastization, it is almost impossible, and the peak of the fourth form of beast transformation is his limit.

Therefore, only the will of the parasitic beast may have hope, but the parasite is too dangerous, so Eru thought of studying the parasite thoroughly first, so as to lay a solid foundation for him to use the parasitic will of the giant beast in the future to break through to the all-beast form.

The two of them go what they need and do not conflict.

"Young Master Leo, I can give you the nutrient pool formula, and even the materials for the nutrient pool formula, I can also prepare it for you, as long as you can be here, I can study it anytime and anywhere, record the number of parasites, and your requirements can be met!"

Eru now wondered why Merlin had reached the third form of beasthood, but was still able to withstand the backlash of the beast's will.

Merlin was a little surprised, Eru's tone was so big, these materials are not simple, very expensive, and the supply is limited, Eru can actually agree directly, if it is true, it means that behind Eru, I am afraid there is a very large force.

However, this is in line with Merlin's previous assumptions.

"I can't keep you researching for a month. In a month, you prepare ten copies of the ingredients I need, and you also have to hand over the recipe of your nutrient pool to me, and you have to prepare ten copies of the materials, how about it?"

This is Merlin's condition.

"A total of twenty materials, it's not a big problem, but one month is too short, at least three months!"

By this time, Eru and Merlin had already begun to bargain, and the final agreement was for two months.

For these two months, Merlin can unconditionally let Eru study at will without harming Merlin.

Eru, on the other hand, had to deliver one material at regular intervals until all twenty materials had been delivered. (To be continued......)
