"As for wanting to leave the Ancient Domain World, this is simple, each of you will receive a metal plate, and when you arrive at the Ancient World, you will see a lot of portals, holding the metal card in your hand, enter the portal, and you will come back here!"

"Remember, you have to hold the metal card in your hand, or you will be transported to some desolate world in one direction, or destroy the world, and you will never have a chance to come back!"

Before entering the Ancient Domain World, a man who should have been about forty years old stood on the shoulders of a mecha that was about twenty meters tall, and reminded Liu Wen of the group of people who were about to participate in the Ancient Domain Expedition.

This man who looks to be in his forties, Liu Wen knows.

He is Bing Xuan, a vice president of the Force Academy, and a top master of the Optimus Empire, with a strength of up to level eight.

The mecha under his feet was an eighth-level mecha, the Xuanfeng Battle Armor.

Bing Xuan also has another title in the Qingtian Empire, the Xuanfeng God of War.

It is worth mentioning that in the Qingtian Empire, there is only one master whose strength has reached level nine, however, he does not have a level nine mecha, so he can't exert level ten combat effectiveness.

In the Optimus Empire, there are no less than 100 masters whose strength has reached level eight, and these people are also the foundation of the Optimus Empire.

In addition, the eighth-level mecha is not something that the Optimus Empire can produce.

Some of the level 8 mechs in the Optimus Empire were obtained from the exploration of the Ancient Domain World, but most of them were purchased from other more powerful empires at great expense.

The Optimus Empire can only barely produce level 7 mechas, and the number of mechs produced per year will not exceed three.

What's more, the portal to enter the ancient world is not only guarded by the Optimus Empire.

In the desert world, there should be many portals into the ancient world, but they are all guarded by other big forces.

If there was only one portal, it is estimated that with the strength of the Optimus Empire, it would have been snatched away long ago.

After all, in the desert world, the Optimus Empire is not the top existence.

In fact, those who enter the ancient realm world have to face not only traps, biochemical beasts and mechanical golems, but also people who also go in to explore.

There are a lot of good things in the ancient world, even if you can't find the top treasures, some non-destructive mechanical parts, bring them out, you can earn a lot of credits.

What's more, biochemical beasts and mechanical golems have energy crystals in their bodies.

These energy crystals can be used directly for mechas.

Energy crystals have the miraculous effect of self-restoring energy, as long as they are not wasted all at once, leaving a part of the energy, it will not be long before they will be restored to full energy.

The only pity is that the fourth-level energy crystals can only be used by mechas below the third-level level.

The combat effectiveness of the mecha can be increased tenfold, and the energy consumed will also be increased tenfold.

Level 4 mecha requires level 5 energy crystals to support it, while people above level 5 cannot enter the ancient domain world at all.

This makes the energy crystallization above level five very precious.

However, every year, there are people who walk shit luck and pick up energy crystals of level 5 or even higher in the ancient domain world.

In this way, the people who explore the ancient world are actually equivalent to humanoid treasure chests.

Killing people and snatching treasures, in the ancient world, is the most common.

In fact, so many people die every year in the exploration of the ancient domain, and one-third of them die in fighting each other.

After warning everyone, Bing Xuan didn't say much, waved his hand, and signaled that everyone could enter the portal and go to the ancient world.

Following everyone, Liu Wen also quickly passed through the portal.

"Shhhh This is the Ancient Domain World? ”

The portal Liu Wen has used it many times, so he naturally has experience.

The portals in the desert world are obviously also one-way, but they are randomly teleported.

Liu Wen's side, apart from himself, the rest is some broken walls.

Look at the collapsed buildings around you, and occasionally you can see the towering walls.

The architecture here is very different from that of the earth and the desert world.

"Cat, Meow, let Catwoman look around!"

Liu Wen was not attracted by the scenery around him that he had never seen, but he did not forget that this was a dangerous world.

With a wave of his hand, Liu Wen released 10,000 catwomen in the dimensional space.

Cats and meows, Liu Wen included them in the dimensional space before, and they were released at this time.

If Liu Wen hadn't included the two of them in the dimensional space and entered the portal separately, he wouldn't have known that they had been assigned to Tiannan and Haibei by now.

10,000 Catwoman, under the command of Cat and Meow, quickly divided into squads and disappeared from Liu Wen.

The Catwoman mother tree is still level four, and the catwomen have been stuck at level four, and a thousand Force forces can't be improved.

However, Catwoman's combat power is obviously higher than that of ordinary people with one or two thousand Force, or even three thousand Force.

The catwoman mother tree is an ancient tree species, and the catwoman cultivated is also much stronger.

"One hundred..."

A few minutes later, Liu Wen had already left his original position and appeared in a location similar to a square.

In Liu Wen's hand, he was holding a fist-sized, purple crystal.

In this meeting, this purple energy crystal, Liu Wen has already gotten dozens of pieces.

However, these are all fourth-level energy crystals, which are only obtained by hunting fourth-level biochemical beasts and mechanical golems.

What made Liu Wen distressed was that in this meeting, a hundred Catgirls under him died.

Fortunately, the corpses of biochemical beasts, each of which contains a large amount of extracted essence, can allow Liu Wen to reproduce the dead Catwoman and let the Catwoman mother tree rebreed, and he can also earn ** extraction essence.

However, Catwomen are all intelligent, and they are all beautiful and cute girls, so Liu Wen can't bear to use them to fight with his life.

From a long time ago, Liu Wen secretly regretted that he should not have chosen to let the catwoman mother tree breed females, he knew that in this way, he would not be so entangled now.

Of course, entanglement is entanglement, but Liu Wen will not give up improving his strength for the sake of the little pimple in his heart.

To put it bluntly, Catwoman is just a consumable, but this consumable is too delicate to make Liu Wen a little reluctant.

A day flies by.

In this day, he was in no mood to calculate the number of catwomen lost in Liu Wen's hands.

It was a fourth-level energy crystal, and Liu Wen already had no less than 100,000 of them in his hands.

During this period, Catwoman also found a sixth-level energy crystal, and several fifth-level energy crystals, which made Liu Wen make a small stroke.

At the same time, in the course of this day, Liu Wen also found two portals, but he had no intention of leaving.

What's more, if Liu Wen wants to leave, he doesn't need a portal.
