In the week after Mia left, Aaron went to the two nearest cities and exchanged magic crystals for a large number of gold coins, which were enough to exchange tens of millions of gold coins, and almost ran out of gold coin stocks in those two cities.

He has a lot of magic crystals, don't look at the exchange of so many gold coins, in fact, it only costs a small part of the magic crystals, if you are about to exchange all the magic crystals for gold coins, at least you can exchange them for hundreds of millions of gold coins.

However, these Aaron estimates that they are enough, and there is no need to exchange for more.

In the distorted space at the exit of the barrier passage, a person jumped out in a flash, and his feet landed firmly on the ground, it was Aaron who had returned from the High Demon Plane.

"It's finally back!It's time to head to the Black Dragon Emperor's capital......" Back in this plane, Aaron looked at the Death Mountains in the distance, and then took a step and headed into the distance.

Before rushing to the Black Dragon Imperial Capital, Aaron first went to the nearest city, where he built a beast cart as a tool to hurry, and also to stay in the car for experimental research while hurrying.

By the way, he hired a driver to drive the car along the way, and Aaron stayed in the car alone.

Before I knew it, a month had passed, and Aaron had spent almost all of his time in the car conducting research, rarely coming out to breathe, and devoting himself to the study of forging body fluids.

"It's exactly what I thought!" Aaron has made great progress in such a long period of research.

Based on his analysis and testing during this time, he has determined how the body forging fluid works to strengthen the body, mainly because the essence blood contains a beneficial ingredient that can promote cell division and evolution.

It is precisely because of these beneficial ingredients that the human body can be strengthened.

However, these are beneficial components that promote cell division and evolution. It must be extracted and separated by some special plant materials, so that it can play its role, and simply soaking in the essence of the blood has no effect, and there must be auxiliary materials.

As for the auxiliary plant materials, they are not rare here, they are relatively common. The price is also relatively low, and the most expensive ones are those essence blood.

Aaron has also analyzed these auxiliary materials, and has also made great progress, and now he can extract the extractive components directly from the plant material, but for the time being, it is not pure enough, and some of the impurities have not been completely eliminated.

Aaron's purpose in researching these forging fluids is to optimize and improve the same level of forging fluids in the future to exert more powerful effects.

It's a long way to the Black Dragon Imperial Capital. Along the way, Aaron would stop from time to time to buy some different materials for the preparation of forging fluids and conduct new research.

Soon, three months have passed, and today is the 100th day of the journey, and I finally arrived near the Black Dragon Emperor Capital, and half a month ago. His research got stuck at a point, and he couldn't find a solution for the time being. It made him very depressed.

At noon the next day, Aaron's beast cart had almost arrived at the Black Dragon Imperial Capital, sitting in the car, looking out through the window, only to see on the horizon in the distance. A magnificent city appeared, which was the capital of the Black Dragon Emperor.

The walls alone are hundreds of meters high, which is very amazing, and the gate of the city is also amazingly large, as if it was for giants to pass through. It was the largest city Aaron had ever seen.

After paying the entrance fee at the city gate, Aaron's animal cart entered the city without any problems.

The scene in the city is very lively, the streets are particularly wide, Aaron sits on the beast cart, uses the chip to scan and analyze the people nearby, and almost no people below the strength of the first-level life form are found, and the people with the strength of the second-level life form can be seen everywhere, and occasionally one or two people who are not much worse than himself will pass by.

After entering the city, he found a place to stay as a place to stay, and then Aaron paid the coachman to go back by himself, and the beast cart was given to him.

After getting a foothold, Aaron began to inquire about some of the situation in the Black Dragon Imperial Capital, as well as some news, and the first thing to determine was where to get the high-grade Brute Beast Essence Blood.

The Black Dragon Emperor is the core city of the Black Dragon Empire, and it is also the place where the rulers of the empire live, in the center of the imperial capital, there is a huge palace, occupying nearly one-tenth of the entire imperial capital.

And the Dilong Academy, where Joseph was located, was located next to it, next to the huge Black Dragon Palace.

The Dilong Academy is also the highest academy in the entire Black Dragon Empire, and it is also the only academy here, cultivating some geniuses, if you don't have enough talent, it is impossible to enter it.

In the Black Dragon Imperial Capital, it is true that you can get a lot of high-level essence blood, but if you want to get the best, you must start with the Dilong Academy, it can be said that most of the high-level essence blood here is in this academy.

In addition, there is also the Dilong Trading House, which is also the largest trading house in this empire, with the ruler of the empire as a backer behind it, and the power is extremely powerful.

However, the high-grade essence blood sold by the Dilong Trading House is limited in quantity, and it is not the best, which is inferior to the Dilong Academy.

One of them can be purchased with money, and the other is dedicated to cultivating the younger generation, and the focus will definitely shift to the academy, after all, this is the reserve force for cultivating an empire, and it is the foundation of an empire's strength.

However, in the Dilong Academy, it is not easy to get the blood of the high-grade essence, first of all, you must be loyal to the empire, and you must make a certain contribution, or you are a person who is valued by the academy.

With Aaron's character, he doesn't like to be high-profile and doesn't like to be restrained, so he doesn't plan to consider starting from Dilong Academy for the time being, but is going to go to Dilong Trading House to see the situation.

In the Imperial Capital, Aaron also learned some other information, related to the forging stage, and those who exceed this stage will enter another level, which is called Leap, which is also divided into nine stages.

So far, Aaron has not seen anyone at the leap level, but in the imperial capital, there will definitely be people at the leap level, and it will not be too few, but he has not seen it for the time being.

According to his own guess, this jump level should be able to correspond to the advanced lifeform stage of the High Demon Plane.

In this plane, those who have reached the leap level will have some means to control the forces of nature, which makes Aaron feel that he may have something in common with mages.

Aaron also had a further understanding of the brute beast, once the brute beast surpassed the ninth level, it was equivalent to the human leap level, and it was called the desolate beast...... (To be continued......)
