Su Luo looked at him with a fixed eye.

Next to the two fairy swords, the two soul fog balls are [Qin Shouren's Soul] and [Snake Man's Soul], thinking:

"So these two souls were prepared for the fourth divine weapon...the fourth?"

Su Luo fell into deep thought.

The clue of the third magic weapon was the mecha, but he wore the mecha and swayed in the Two Realms Mountain for a week or two, but he had not even summoned his hair. He could only continue to try until the newly purchased Captain Red Moon arrived.

And the fourth magic weapon...

Su Luo looked at the newly added companion building - duel arena, and guessed in his heart:

"This is the clue... Maybe you have to invite a strong man to fight before you can open it? Nine orifices are definitely not possible. Qin Shouren is the classical Taoist master of Nine orifices. Maybe he is duel against opponents at a higher level, at least at the outer level?"

Su Luo frowned and thought for a while, but couldn't get the exact answer and sighed:

"I can only try to verify it slowly."

After saying that.

Su Luo reached out and grabbed the soul fog ball of [Qin Shouren's Soul] and sent it into the duel arena together.

The gray fog rises.

The two pillars diagonally at the ring shook slightly, and all the two souls were absorbed into them, forming two lines of text:

"Qin Shouren's soul has been deposited into the human pillar. Should we force a human strong man with similar strength and similar attributes be invited?"

"The soul of the snake man has been deposited into the demon pillar. Are you forced to invite powerful demons with similar strengths and attributes?"

The ring was slightly shocked, and large sections of information flowed into Su Luo's memory, allowing him to basically understand how to use the [duel arena].

"The invitation range is ten thousand times the range of...the spiritual mind power scanning?" Su Luo closed his eyes and concentrated, trying to integrate his spiritual mind power into the demon pillar on the ring.

"Bang!"

The soul of the snake man suddenly shattered, and all its soul fragments merged into the arena and turned into an amplifier for scanning the mind power!

Instantly.

Su Luo slowly closed his eyes, but his gaze seemed to penetrate the dark void outside the world in the painting, traveling thousands of miles, and throwing into the vast mountains of the two realms!

As mentioned before, in order to deal with the Three Heads of Dragons, Qingcheng always wanted to hire an outdoor spiritual master to scan the grassland on a large scale, but no one applied for it, causing the lewd dragon to storm the grassland for a long time.

In other words.

One of the specialties of spiritual mind masters is to use spiritual mind power to detect outward on a large scale. The detection range of the externally-level powerhouse can even observe existences a hundred miles away.

Although Su Luo is just a second-level spiritual master, he can still roughly scan the environment within an radius of 800 meters.

therefore.

Su Luo's invitation range is within a radius of eight thousand miles.

It not only covers the entire Qingcheng, but also scans the Ailao Mountains on the border of the Two Realms Mountains.

Su Luo guessed in his heart that when his mental power was further improved in the future, he might be able to project the range of [duel arena] to the more distant Longmen Mountains, the Tianxing Snow Mountain area, and even directly project to the demons' base camp-

Demons and worlds!

If the demon princess is taken into the world in the painting, wouldn’t it be... imprisoned play?

Ahem.

Get back to the point.

In fact, the greatest significance of [Duit Arena] is that it is in a safe rear but can support the front line!

Su Luo can stay in Qingcheng. If you lie comfortably at home, you can continuously remove some demons from the mountains of the two realms, thereby reducing the burden on the human defense line!

He recalled what he taught in high school geography teachers:

"The Ailao Mountains are adjacent to the Wanniu Grassland and are the boundary between the northwest grassland of Qingcheng and the Wanniu Grassland. The terrain stretches for thousands of miles.

The Great Xia Dynasty once sent millions of troops in this mountainous area to defend the invasion of the northern Silver Moon Wolf Demon.

Five years ago, the Dragon Slaying Academy successfully captured the Wanniu Grassland.

The military breathed a sigh of relief and left only at the key locations, seventy-two strongholds, thirty-six military fortresses, and more than 200 patrols. The main task was to prevent a small number of traversing demons and was also the last line of defense for the human race to defend the enemy outside the border!"

Su Luo's eyes were burning.

After learning how to use [Dull Arena], he immediately remembered a widely circulated folk song:

"A nail was lost and a hoof was broken;"

"A hoof broke and a war horse broke;"

"Broken a war horse and injured a knight;"

"Injured a knight, lost a war;"

"Lost a war, and an empire is destroyed!"

Even a thousand-mile long dike will collapse, collapse and be destroyed by a small ant hole!

Just imagine, during the fierce battle between the demons and the human army, the [duel arena] suddenly at a critical moment, at a critical moment, the key position will continue to send one demon after another thousands of miles away. What tactical effect will it have?

There is no doubt.

This is the best use of [Dull Arena]!

Win a thousand miles away!

A hint of excitement flashed in Su Luo's eyes and said excitedly:

"With the duel arena, I am just a rusty iron nail, an ant on the river bank, and I have no idea that they have lost inconspicuous wars!

In the end, the clan will be destroyed!”

Su Luo closed his eyes again, glanced back and forth in the Ailao Mountains, searching for traces of the battle!

Not long after.

Two inconspicuous battlefields suddenly came into view.

First.

At the edge of the Ailao Mountains, there is a relatively remote valley that is very suitable for grazing buffaloes.

The human race built a small stronghold here and moved a large number of herders to settle here.

But just yesterday, the wolf demon clan named the Frost Wolf clan surrounded hundreds of warriors and thousands of people in the cave.

At most two days, the defensive magic array at the entrance of the cave will be broken!

Second.

At an altitude of 5,000 meters in the Ailao Mountains.

In an abandoned cave.

While patrolling with a squad leader, they were accidentally attacked by more than fifty green-skinned zombies. In desperation, they had to hide in an abandoned cave and use the narrow terrain to block the attack of the corpse group!

Perhaps in a few hours, these six soldiers who were on the front line would be bitten to death by zombies and become members of this group of wandering green zombies.

Obviously.

The cave is the most critical place, and it is imminent!

"Aid emergency, save people!"

Su Luo no longer hesitated and immediately woke up the [duel arena]. An invisible deterrent force suddenly rushed out of the abandoned cave!

The gray fog condenses a line of prompt text:

[The target has been locked, and the demon will enter the duel arena in one minute. Please be ready for battle!]

Su Luo held his breath and jumped onto the ring first, waiting silently for the arrival of the green-skinned zombies.

Next second.

A green phantom gradually emerged in the center of the arena.

It was a little confused at first, but when it saw the only human present, a pair of red and rotten eyes immediately showed a creeping cold light!
