Although the theater of doomsday map is a relatively new map, the problem is that the challenge mode is to fight zombies without changing the medicine.

Arriving at the Doomsday Theater, Xiao Han continued to use the wings of the dragon to fly into the air, and after slaying all kinds of small zombies at the speed of light, the final big boss, the Destroyer, walked out from behind the curtain carrying Gatlin.

This guy has little yellow hair on his head, like a killer horse, and he staggers when he walks. He is definitely a delinquent young man.

But this guy looks like he's worth 2,580,000, but he's actually a loser, and his real strength is nowhere near that of the Mad Titan just now.

Xiao Han had become addicted to using mechas to torture bosses. He summoned the Holy Light mecha and killed the Destroyer and its zombies like chopping melons and vegetables.

"Ding! Dear Trialist Chang'an, congratulations on successfully killing the Destroyer, clearing the copy of "Cross Fire: Doomsday Theater", and receiving rewards: Physical attribute points x 10, and advanced ability upgrade book x 1!"

"Do you want to continue challenging the welfare copy? Continuing to challenge will consume one welfare copy card. If you terminate the challenge, you will be moved out of the welfare copy!"

"I guess, it turns out that the bad boss has really good stuff, and he actually got an advanced power upgrade book!"

At this moment, Xiao Han was grinning from ear to ear. You know, the value of the advanced power upgrade book is even higher than that of most powers!

After all, the higher the level of superpowers, the harder it is to upgrade, but the more powerful they will be. Even the true power of many superpowers can only be reflected in the last three levels.

An advanced power upgrade book means a master-level power. And a grandmaster-level power is the lowest level at which the true power of the power can be exerted.

This is the value of the advanced power book!

Xiao Han now has two elite-level abilities, "Gift of Life" and "Teleportation", and he can choose to upgrade one of them to the Grandmaster level at any time.

But after struggling for a long time, Xiao Han decided to save this advanced power book for the time being. This thing can be used as a secret weapon!

At a critical moment, depending on the situation, improving a special ability will definitely have unexpected effects.

And although Xiao Han now possesses many powers, he is not very satisfied with these powers. So Xiao Han has been looking forward to seeing if he can get a more heaven-defying power.

At that time, wouldn't it be more delicious to use the advanced power upgrade book?

After making up his mind, Xiao Han immediately made a decision: "Continue to challenge!"

"The challenge continues, consume a welfare copy card, and then proceed to the next stage of copy transmission. The target copy is "Cross Fire Thunder Tower"!"

A white light flashed before his eyes, and the scene around Xiao Han changed again. He came to the interior of a high tower filled with a large number of technological elements. This was the Thunder Tower.

In the picture of Thunder Tower, the main opponents are not zombies, but some strange-looking small robots. Occasionally, a few red zombies that run very fast will pop out.

When this picture came out, CrossFire had already begun to decline. Seeing that the market could not be saved, the production team of CrossFire simply began to break the pot.

All kinds of weapons and characters that are no different from cheating are emerging in endlessly, with only one purpose - to make money!

As for how the game is doing, sorry, this is not the focus of the production team.

Therefore, the picture of Thunder Tower is very boring overall. Even if the production team worked hard to add some new ideas, nothing can be changed.

Xiao Han's Holy Light Mecha, in this picture, is the biological father of all mechanical enemies. The technological level of the Thunder Tower is far from being able to create a killer weapon of the level of the Holy Light Mecha.

So along the way, Xiao Han first killed the minion, then the huge ugly spider, and then the spider knight who looked awesome after coming out, but was actually just weak.

Finally, when the mechanical dragon named Evil Emperor Dragon Armor came out, Xiao Han once again felt how perfunctory the CrossFire production team's post-production work was.

The name of this evil emperor dragon-armored beast is quite domineering, but its appearance looks too crude.

An iron lump with several gear-like circles behind it becomes a mechanical dragon. This is completely a failed primary school student's painting!

"Well... I really can't accept your name with the word dragon in it, so I can only kill you as soon as possible!"

With that said, Xiao Han first took out the Hammer of Severe Injury and used one hammer to break the defense of the Evil Emperor Dragon Armor. Then, the Holy Light Mecha fired two armor-piercing bullets to continue breaking the defense.

Then he drew out his titanium alloy sword, jumped down from the Thunder Tower, raised the knife and cut off the head of the Evil Emperor Dragon Armored Beast.

"Ding! Dear Trialist Chang'an, congratulations on successfully killing the Sky Spider, Sky Spider Knight, Evil Emperor Dragon Armored Beast, and clearing the "Thunder Tower of Crossing Fire" copy. You will be rewarded: mental attribute points x 10, speed attribute points

×10, Sky Spider Essence ×1!”

"Do you want to continue challenging the welfare copy? Continuing to challenge will consume one welfare copy card. If you terminate the challenge, you will be moved out of the welfare copy!"

"Continue the challenge!"

The rewards this time were relatively average, but you can't always expect to get something like an advanced power upgrade book, so Xiao Han decisively decided to go to the next level.
Chapter completed!
