"What's going on out there, what's going on with this sound?" Han Yue shouted a little nervously.

Not to mention Han Yue, even Di Wei and He Yeping also had panicked looks on their faces. This is not to blame them, they have experienced so many dangers in the green moor, they are now a bit of a rumor, and the grass and trees are all soldiers. When something happens, they get nervous, for fear that something terrible will come out.

"It's okay, this is the sound of the energy cannon, I'm afraid the top level of the Yuanlan Municipal Government can't sit still anymore, so I'm sending people over." Su Han said comfortingly.

"Energy cannon?" Han Yue suddenly gasped, she still knew the name of the energy cannon, "Could it be that the Yuanlan City Government plans to directly bomb this green swamp area?" ”

Di Wei and He Yeping listened to Han Yue's speculation and were shocked, this possibility is really too great. If you forcibly bombard this green swamp area with energy cannons, I don't know how much energy it will cost. But these are the government's business, and they have nothing to do with them.

"Let's go, let's get out quickly, I think there will be an army to firmly control this ancient city soon." Although I don't know when this ancient city was built, I think it is very valuable for historical research. ”

Su Han and the others walked out of the main hall one after another, and walked along the street in the direction of the ancient city gate. Along the way, they also met several other warriors, and by looking at their empty hands, they knew that they had gained nothing. It seems that this ancient city is nothing more than an empty city, and as for the treasure, it is estimated that the four murals are worth it.

The sound of the energy cannon did not continue to sound, and the officers parked their armored vehicles outside the ancient city, and they looked at the ancient city with a look of shock on their faces.

I don't know what has changed in this green swamp area, and so many strange creatures have appeared at once. Even if these are the things, an ancient city has appeared out of thin air in this inner belly, which makes them have to be shocked.

The eerie green swamp area, the mysterious ancient city, all this is full of mysteries.

Soon, several officers discussed, and they first sent some soldiers to be stationed outside the ancient city. One of the officers began to contact headquarters, and he informed the strange ancient city that had suddenly appeared. The other officer began to assemble his men and prepare to enter the ancient city to find out.

"Hmm...... Is there something in this ancient city? Just as the officer was about to take the men in, he suddenly saw several figures running towards them in the street.

"Weapons ready!"

As soon as he gave the order, the soldiers next to him all pointed their guns at the gate of the ancient city in front of him.

The figure was getting closer and closer, and it didn't take long for it to appear. His heart suddenly breathed a sigh of relief, it turned out to be an ordinary martial artist, he thought ......

The officer shook his head, flicking the ridiculous thoughts out of his mind. After entering this green swamp area, he encountered a lot of strange creatures, such as the bloodthirsty green vine, and he thought that there would be some terrifying creatures in this strange ancient city.

As soon as Su Han and the others walked out of this ancient city, they saw black gun barrels facing them, and their bodies trembled, if those soldiers fired, their lives would be lost here.

"Don't shoot!" A gruff voice rang out.

Su Han looked over, the person who led the team before.

The leader of the group stepped forward and negotiated with the officer for a while, and then the officer waved his hand, and the soldiers put their guns back.

It didn't take long for the warriors in the ancient city to come out one after another, and they looked at the army in front of them and were a little overwhelmed for a while.

At this moment, a young officer stepped out of the loading truck, who was the same person who had previously been in charge of contacting headquarters. He walked up to the officer who was in charge of leading the soldiers to explore the ancient city, and said, "The above said that we should not do anything, just wait here, and the people from above will arrive soon."

"It alarmed the people above." The officer was shocked, but then he thought about it, and he was relieved. Looking at the young officer's puzzled expression, he explained the origin of these warriors around him again.

"Open your backpacks, you ...... You...... You...... Go check them out one by one. The young officer pointed to the soldiers, and then to the warriors.

Su Han took his backpack off his back and opened it, only some daily items in the beast area, nothing else. The other warriors also obediently opened their backpacks, and it was obviously unwise to oppose these armies.

The soldiers examined the backpacks carefully, and soon they were done, and there were no suspicious items, except for the fact that two people's backpacks were found to contain some illegal drugs that the government did not allow to buy and sell.

Looking at the somewhat pale faces of these two people, the young officer frowned, but did not send anyone to arrest these two people.

These illegal drugs are not drugs that harm others, but drugs that harm themselves. These potions are relatively cheap because their effects are so unstable, and they are sold on the black market.

He checked the backpacks of these people just to find out if there were any items related to the ancient city, and he didn't want to worry too much about the potion. After all, many martial artists have no power, so naturally they have no resources, so they can only buy these forbidden black medicines.

……

Whew

A few minutes later, several heavy armored vehicles suddenly drove over from a distance, and two old men walked out of the heavy armored vehicles. The two old men looked older, but they were still strong and strong. Several officers watched the two old men get out of the car, and they immediately greeted them, and it was clear that the identities of these two old men were not simple.

"Go aside, and don't make any noise." The young officer waved his hand at Su Han and the others.

The two old men slowly walked to the edge of the ancient city, but they did not go in, but stretched out their hands and kept touching the walls of the ancient city.

Their movements seemed extremely gentle, as if they were not touching the walls, but a rare treasure. There was silence all around, and no one dared to make a sound at this moment, and they all quietly watched the movements of the two old men.

The faces of those officers looked a little expectant, and it could be seen that they knew a little about the movements of these two old men, while Su Han and the others were confused about this.

After a long time, the two old men's brows furrowed tightly, and they had encountered a problem.

"That's all I can do." One of the old men suddenly opened his eyes and said.

The other old man's eyes froze suddenly, and then he slowly said a word: "Good!"

I saw that the old man in black bit his finger, and he slowly dripped blood on the walls of this ancient city. The blood didn't immediately slide down the wall, the old man waved his finger at the wall, and in a few breaths, he drew a hexagonal rune on the wall. It's just that the rune is not complete, and there seems to be something missing in the middle of it.

After the old man in black finished his movements, the old man in gray also bit off one of his fingers, and then he put this finger in the middle of the hexagon. After his blood touched the wall, in an instant, several twisted words emerged from the hexagonal corners.

Su Han looked at the distorted words that appeared out of thin air on this wall, and he was stunned for a moment, how similar these distorted words were to the tadpole inscriptions on the Nine Heavenly Monuments he had seen on the mural earlier. It's just that the tadpole inscriptions on the nine tablets are too complicated, and these characters are simplified versions.

After the hexagonal runes were fully formed, the two old men suddenly sat cross-legged on the ground, their eyes closed, and their mouths were muttering, as if they were chanting some incantation.

At first, nothing had changed, and as time passed, the bodies of the two old men suddenly blurred. It seemed that the space had been cut apart all of a sudden, so much so that the space seemed to overlap countless figures.

"Soldiers, Soldiers, Laws, Formations!"

After a long time, four sonorous words suddenly came out of the overlapping space. These four words seem to have gone through countless years, through endless space, and slowly flow out in the long river of time, with unspeakable vicissitudes.

These four words did not come from the mouths of the two old men, and with the strength of these two old men, they could not say such words, as if these four words should not exist in the world.

After these four words sounded, the hexagonal rune on the wall suddenly flickered, and several tadpole-like words kept changing, and these four-character mantra was the heart and soul of this rune.

Rumble!

There was an earth-shattering bang, and the two old men were suddenly shocked out of the chaotic space, and several mouthfuls of blood spurted out of their mouths. The spatial shock just now caused them to suffer a lot of injuries.

Several officers immediately stepped forward and helped the two old men to the side.

"Old Chen, Old Qian, are you all right?" Several officers asked worriedly.

"It's nothing, and we two old bones don't have much time anyway."

"I didn't expect to be able to see such a complete 'instrument' in the lifetime of the two of us, and it is also a 'instrument' from ancient times, the sky is not thin on us!"

There was no malaise in the eyes of these two old men after being seriously injured, and there was only endless ecstasy in their eyes.

Utensil! Hearing the words of these two old men, these officers immediately gasped, and it was an almost complete instrument from the ancient world!

"I didn't expect there to be a 'vessel' from ancient times here, and now I finally understand." At this moment, a crisp female voice suddenly sounded.

Hearing this voice, Su Han turned his head violently to look, sure enough, it was her! The voice was all too familiar to him.
