Samsung Academy has a long history, including buildings that are more than 10,000 years old, and the 'Battle Arena' is such a place with a long history.

Compared with the long history, his humble appearance is also one of his characteristics.

From the outside, this is just a building with ten gates opening from ten directions, and from a distance it looks like a large pavilion with ten pillars supporting the roof, without superfluous decoration, and it is impossible to see the vicissitudes of ten thousand years.

The area within a radius of only one kilometer is very inconspicuous compared to the entire college.

Although this place may seem like an inconspicuous and humble place, it is quite familiar to most students at Samsung College.

When a large-scale event is held at Samsung Academy, most of them will locate the 'battle stage' as the event venue, so how can students be unfamiliar with such a place?

Although it seems to be a small place, it is actually a lot inside.

The 'Space Folding Technique' is no stranger to most Array Mages, because the first practical item Space Pocket that a Formation Mage can make is made with this technology.

However, although they are no strangers to the 'Space Folding Technique', few people even among the Array Mages know that there is a similar advanced technology on top of the Space Folding Technique, which is called the 'Transparent Space Folding Technique'.

Transparent? Yes, just two more words, and the technical content becomes very different.

'Space folding technology' is to superimpose a closed space with a combination of guò formations, so that the inside becomes larger without changing the outside, so as to achieve the purpose of enlarging the space.

However, the 'space folding technology' has one obvious shortcoming, or shortcoming. No matter how huge the space is. None of them can contain living creatures.

This is the case because. While the application of the 'Space Folding Technology' is successful, it also indirectly seals the connection between the inside and the outside world, and indirectly guides the air to not flow, even when accessing items, it will be blocked by the formation, so that the air cannot enter it.

If there is no air, how can a living thing be placed?

'Transparent space folding technology' is different, it is a kind of space folding technology while maintaining it. It is a technology that connects the space with the outside world at all times.

At this time, in the 'battle stage' with a radius of only 1,000 kilometers on the outside, there is a 1,000-kilometer radius inside, and the staff members are busy and busy, checking every space inside.

In order to build a suitable venue for the Raiders of the Lost Ark, and in order not to have technical negligence on the field, the staff is making final adjustments to the site in preparation for the upcoming ceremony.

At the same time that the staff was nervous and busy. In another place at the same three-star academy, on top of a teleportation array. Xidong's figure appeared in the three-star academy with a silvery-white light.

At this time, Xidong looked no different from entering the 'Dragon Valley' from the outside, and even the clothes on his body barely changed.

However, only Xidong himself knows what he himself has experienced.

The clothes on his body are no longer the same as the one he wore when he entered the 'Dragon Valley', and ordinary clothes can't withstand high-intensity battles at all.

Glancing at the noisy crowd around him with somewhat numb eyes, the expression on Xidong's face slowly relaxed.

After relaxing a bit, he stepped off the portal, his figure slowly blending into the crowd of people on the street.

The long time of killing made Xidong look a little numb, without the company of his kind, even if Xidong's nerves were already very stoic, he could not be affected in the slightest.

After getting rid of the black-robed man, for some reason, the black-robed man never caught up again, which is a good thing for Xidong and a bad thing at the same time.

When there is a black-robed man, at least Xidong can still guard against the other party, so as not to repeat the same thing monotonously in the following time.

Killing, in the end, this is the life of Xidong after he broke away from the black-robed man.

After giving so much, of course, there is also gain.

Although the skills on the pages of the soul book are still those and the level has not been improved, whether it is the application in battle or the proficiency of the skill itself, it has improved accordingly.

dragged his tired body to move with the flow of people, and it didn't take long for Xidong to come to the door of the bone-burying shop.

Standing in front of the boss 'Dragon' and facing this familiar face again, a smile appeared on Xidong's face.

"See you again, Boss Dragon, you've been doing well lately." For the person 'Dragon', Xidong maintains a certain favor.

Hearing Xidong's polite greeting, 'Long' didn't react much, just looked at him and nodded simply, which was regarded as a response to Xidong's greeting.

Not caring about the 'dragon's rude reaction, after seeing the other party nodding, Xidong waved his hand at the counter in front of him.

Xidong came to the bone store to bury the bone, but there was a serious matter, and greeting each other was just politeness when meeting.

Out of nowhere, with the wave of Xidong's arm, a pile of cards suddenly appeared on the empty counter.

Seeing the sudden extra cards in front of him, the dragon's eyes opened slightly.

It's just a rough estimate that there are more than 200 cards in front of him, and with such a large number of cards, even a person as indifferent as 'Dragon' can't maintain the calmness he deserves.

These cards on the counter are all hunted in the west and east, and the level is not too high, most of them are between seven or eight levels, but the problem is no longer the level of the item, but its quantity.

In fact, without feeding the 'Snake Forgetfulness', it's normal to get these equipment cards for high-intensity battles like Xidong.

The dragon's surprised expression was in Xidong's eyes, and the smile on his face widened, and Xidong opened his mouth.

"These cards are all sold, and the value is to exchange them for a high-level food card." Before the 'dragon' could recover from his surprise, Xidong's voice had already sounded.

"One?" The 'dragon' spoke, his voice questioning.

However, although these cards are of low level, if they are exchanged for a food card, they can be exchanged for high-level food cards, after all, the value of food cards is much lower than equipment.

"That's right, one." Xidong replied affirmatively, once again clarifying the answer.

The dragon didn't hear it right, and Xidong didn't say it wrong, these cards in front of him, Xidong really only intended to exchange for a food card.

This is done with Xidong's own considerations.

That's right, if Xidong uses these cards to exchange for the same level of food cards, he will get a lot, and after fully absorbing them, he will definitely get more food energy than a high-level card.

However, not to mention that Xidong wants to quickly improve his strength now, even at this time, there are also a large number of food cards stored in Xidong's space pocket, and low-level food cards are of little significance to Xidong at this time.

After a long time of exploration, Xidong also figured out some problems for the improvement of his own strength, food cards are undoubtedly the fastest way to improve his strength, and low-level food cards can be hunted by himself, and he can quickly obtain them without them, but high-level food cards are what he is very eager to get.

The 'dragon' standing in front of Xidong didn't hesitate after receiving an affirmative answer again, but just glanced at Xidong with unknown eyes, picked up the cards in front of him and looked at them one by one.

The 'dragon' checked it quickly, and in a short time, the card in front of him had already been checked by him.

There are 307 cards, which is a lot more than the imagination of the 'dragon', most of which are level seven or eight cards, and there are also some level nine cards.

Frowning slightly, the dragon pondered for a moment, as if he had made up his mind, and he looked at Xidong.

The dragon said, "There are no more high-level food card shops anymore, but I can trade a private food card with you." With that, the dragon threw a card to Xidong.

I didn't care much about taking the card thrown by the other party, and glanced at it.

The next moment, Xidong's pupils shrank slightly, and he carefully checked the card in his hand.

For Xidong's reaction, the 'dragon' didn't urge, and quietly watched Xidong's inspection. (To be continued......)
