The old dragon

"Wait for me, teacher, sister, I will definitely return as a strong man when the third nest disaster strikes, to protect everyone and the entire Black Lantern Castle." Su Huan clenched his palms tightly, facing the snowflakes towards the A city full of opportunities and challenges.

Gradually, his figure became blurred in the wind and snow.

……

Before he knew it, Su Huan had already been in Thunder Thunder Fortress City for half a month.

Su Huan's understanding of Thunder Fortress City, a huge city with a population of more than 5000 million, has been ignorant at the beginning, and now he knows a thing or two about all aspects.

After Su Huan came to Thunder Thunder Fortress City, the first solution was naturally to live.

A dignified and experienced professional driver, he can't sleep on the street.

However, for legal residents with permanent residency, accommodation is nothing more than payment.

And Su Huan is not short of this small amount of money, even if he was fined hundreds of millions last time, he still has hundreds of millions of thunder coins left, which is enough for him not to worry about money in daily expenses.

But as a newcomer.

Su Huan didn't rent a house for the first time, but lived in a hotel temporarily like in Steel Branch City.

I plan to get familiar with the environment in the future before making plans.

Because they live in a hotel, the training of controlling pets becomes a problem.

Although the hotel also provides training venues.

But those training grounds for controlling pets are not only small in size, but there are still a lot of people.

It is not prepared for Su Huan, a professional-level driver who is a terrifying kind of pet driver.

At most, it is competent for dangerous training with weak strength.

This also made Su Huan have to look for a training place for controlling pets on the first day of staying in the hotel.

Fortunately, Thunder Fortress City not only has a large population, but also has various facilities that are exceptionally complete.

Su Huan directly found a nearby pet control training dojo to conduct regular training for pet control.

Within these fifteen days.

It is naturally impossible for Su Huan to spend all his time on pet training.

He has more pressing matters.

Collect the transformation materials needed to control pets.

During these days, Su Huan indeed found several useful materials.

But that price is not something Su Huan, whose wallet has shrunk significantly, can bear.

No way, Su Huan could only be forced to start a business to make money, and it was very effective.

The most direct manifestation is that his funds have doubled tenfold within fifteen days.

Su Huan initially planned to use some of the knowledge of the old Longdian to make a profit.

But when he was doing market research and wanted to find out which products were the best-selling in Thunder Fortress City.

An energy crystal shop that I passed by unexpectedly, the price of various energy crystals in it made Su Huan's heart move, and he thought of something.

After the energy-absorbing tree transformed into an energy-absorbing tree dragon, a series of abilities of the energy-absorbing tree dragon have been greatly increased.

Among them, a certain ability of the energy-absorbing tree dragon is the source of Su Huan's association.

The energy-absorbing tree can absorb a large amount of ordinary energy crystals, produce high-energy crystal fruits purely made of energy, and can control the shape of the fruit, allowing it to grow in the form of squares or balls.

These high-energy fruits are not just another high-energy crystal with similar shape.

The prices of ordinary energy crystals and even impurity energy crystals are extremely cheap.

High-energy crystals are of high value due to their rarity in nature and their own particularity.

Purifying ordinary energy crystals into high-energy crystals is something that is difficult for ordinary pet masters of the plastic energy system to do.

The reason why the energy-absorbing tree dragon can do it is because of its special ability.

The extraction of the essence of the phagocytosis system can not only extract the essence, but also the pure energy in the energy crystals rich in impurities can be easily extracted.

Su Huan united knowledge and action, and immediately bought a large number of defective energy crystals from the energy crystal store to test.

In the end, it was determined that the profits of high-energy crystal blocks formed by using defective energy crystals differed by ten or twenty times.

Moreover, the conversion efficiency of the energy-absorbing tree dragon is extremely high.

Even if the energy-absorbing tree dragon only spends five or six hours a day transforming high-energy crystals.

Su Huan's net income also exceeded [-] million thunder coins.

In just half a month, he has accumulated a fortune of one billion.

This also deducted the time for Su Huan to find a market to sell the high-energy crystal.

In fact, Su Huan can make a lot of money just by throwing out a little knowledge of the old Dragon Code, but this way of making money is more uncertain and dangerous.

It would be safer to make money by selling high-energy crystals.

High-energy crystals are scarce strategic resources that are in short supply.

Whether it is the cultivation of pets, the manufacture of strange things, energy supply and other fields, it has great use value.

And often in short supply.

Through investigation, Su Huan set his shipping price one or two percentage points lower than the market price, and easily obtained more than one billion thunder coins in cash through several big customers.

With one billion thunder coins, I'm afraid you can buy two or three of the super-terrorist cubs that are not too rare.

For this reason, Su Huan also set up a high-energy crystal sales company, Tianyun Company, which is responsible for selling high-energy crystals.

The name directly copied the name of the Black Lantern Fort Sky Fortune Trading Company.

Su Huan, who had a lot of money again, began to search for traces of various dragon transformation materials.

Among them, the materials needed for the second metamorphosis of the crystal rock dragon, treasure hunting dragon beast, light and dark princess, shadow bear, mud dragon and even the mature metamorphic basilisk dragon are the most important.

The transformation of the shapeshifting basilisk dragon again has already been unsealed in the old dragon code.

In addition, the cultivation of the two bloody tyrannosaurus leaders is imminent.
