Xuanyuan Hong immediately followed, and came to the place where Hong Liu found the traces to take a look, and it was really a very new trace, it seemed that it was within two or three days, although the blood stains had dried up, but it could be seen that it was left recently, and it was obvious that someone had taken the lead.

However, on the ground and walls, there were no traces of battle damage, and Xuanyuan Hong immediately realized that it was the memory metal that had recovered the damage.

"Be careful, someone has already come in before us. Xuanyuan Hong reminded that the internal communication of the fortress was blocked, and after a certain distance, their communicator could not receive the signal of their companions, and not only that, but even their own divine thoughts were seriously affected.

Once they are too far away, they will lose contact, and there will even be a possibility of separation, which is not okay.

Originally, Xuanyuan Hong planned to conduct a search separately, but because of the limitation of the contactable distance, he chose to move forward together, and the distance between each two people was within the contactable range, which not only avoided falling into the trap at the same time, but also expanded the search range.

It didn't take long for everyone to come to a long passage, which was thirty meters long, and there was no portal in between.

"Be careful!" Xuanyuan Hong reminded, such a straight passage gave him a strange feeling that the passage might be weird.

Xuanyuan Hong was the first to enter the passage, and it was fine if he walked forward for about twenty meters, but when he took another step forward, three small balls catapulted from the ceiling, each of which was only the size of a fist, and there was a transparent crystal with a diameter of one centimeter on the front, and all the others were silver-white metal.

The metal ball was eerily suspended in the air like this, without any power phenomenon, just like a fish in the water, which made Xuanyuan Hong very vigilant, I don't know how many years the abandoned space fortress is still running, and it is working well.

After they entered the Battlestar, they felt gravity, they didn't want to be weightless in space, and there was fresh air, all of which showed that whether there were people in the Battlestar or not, the Battlestar was still operating, and it was working very well.

In the face of such a strange fortress, Xuanyuan Hong certainly had to be careful, especially the inexplicable fist-sized sphere in front of him.

The team members who followed behind him also did not follow up at his signal, but they all stared vigilantly at the silver-white orbs that appeared in the air.

"Intruder, please exit the fortress immediately, or you will be killed!" When everyone was confused, a voice from an unknown source came out, warning, it turned out to be a warning for them to leave, obviously the defense system of the space fortress was working normally, at least partially.

Xuanyuan Hong realized that the silver ball was likely to be a weapon system, but such a small ball was difficult for people to associate with a high-power weapon, but after all, it was a product of ancient technology, and he didn't dare to guarantee how powerful the ball was.

Xuanyuan Hong did not retreat, but prepared to counterattack, paying close attention to the three balls in the air.

"Intruder, please exit the fortress immediately, enter the attack program, the countdown begins, ten, nine,...... , five ......" warning continued to sound.

At the same time, the crystal on the front of the metal ball lit up, obviously ready to attack, and the countdown had already begun, just wait for the countdown to end and the attack would begin, but Xuanyuan Hong didn't know the form of the attack yet, and could only predict the source of the attack.

"Three, two, one, zero, attack begins!" The countdown ended, the crystal on the front of the metal sphere turned red, and a beam of red light shot out of the crystal, and the three silver balls shot out three red rays, and at the same time shot at Xuanyuan Hong, who was in the passage.

Xuanyuan Hong had already dodged away, and when the countdown returned to zero and saw the crystal turn red, he had already realized that something was wrong, and dodged away in advance, just when he left his original position, three red lasers passed through his position just now, one shot at the head, one shot at the throat, and one shot at the heart.

Different from the lasers that have been seen before, the three lasers are very powerful, even if they are not hit, Xuanyuan Hong can also see from some external features, the power of the laser is more powerful than that emitted by modern technology, many characteristics are different, and the attack effect caused is also very different.

"It's a laser gun, but it's a little smaller, how strong can a laser the size of a fist emit be?"

"It must be very strong, you can see that when you shoot the ground, there is a popping sound in the air, obviously a powerful burst of energy. ”

"Isn't the captain in danger in this way, let's knock out three balls and help the captain get out of danger!"

At this time, Xuanyuan Hong's nine subordinates had already come to the end of the passage, but Xuanyuan Hong asked them to wait outside, so they were not attacked, but they put themselves in their shoes for a while, and it was them, and no one was sure to avoid the laser shooting.

The silver orb reacts very quickly, the laser shoots very quickly, and it looks incredibly powerful.

Shoot!

With a little hand, Xuanyuan Hong shot out a sword qi, but because he was still dodging the laser's attack, he couldn't do his best when he shot, and the shot had to be fast, and he couldn't stay in one place for a long time, otherwise he would be in danger of being hit.

"No, they're moving too fast, I can't lock on, and a forced attack might hurt the captain!" Hong Yi looked and shook his head.

"Me too, I can't keep up with the speed!" Hong Er is the same, and the next Hong 3, Hong 4, Hong 5, Hong 7 and Hong 8 are also difficult to lock.

"I can barely lock on, but I can only lock on to one, and the other two can't do anything!" Hong Liu, who is a professional archer, tried it, his bow and arrow can lock onto the silver ball, but it can only attack one target at a time, otherwise it will be in vain.

It's hard to guarantee that when you attack one, the other two won't change, and if you get the captain involved because of this, it's a big problem.

"I can also lock one, let's knock out two, and the remaining one, the captain should be able to handle it!" Hong Jiu tried to lock and found that he could also lock one, he was the only one of the nine people to increase his life, and it was not strange that he could lock a silver ball.

Three silver balls, Xuanyuan Hong seems to be able to cope with it quite easily, at least from the beginning to the present, the critical situation has not appeared, but there is a saying called long nights and dreams, no one can guarantee that the time is long, Xuanyuan Hong will not be shot due to fatigue and negligence.

Whoosh!

Hong Liu and Hong Jiu shot at the same time, and an arrow hit the silver ball on the left side, the power of the special armor-piercing arrow was very amazing, and it shot into the silver ball more than an inch deep, which made Hong Liu very surprised, his armor-piercing arrow was special, and the most critical edge of the arrow was made of materials equivalent to that of a fifth-level divine soldier, although it was only a little bigger than a grain of millet, but the penetration was very amazing.

However, such an armor-piercing arrow only shot into a little more than an inch deep, and the silver ball was too strong, right?

However, his purpose had been achieved, and the silver ball emitted a puff of green smoke and fell to the ground with a click, apparently scrapped.

Hong Jiu next to him also hit another silver ball, but he didn't have an armor-piercing arrow, the powerful sword qi knocked the silver ball out, and hit the wall with a bang, the wall was knocked out of an obvious trace, and the crystal on the front of the silver ball was shattered.

A puff of green smoke also came out and fell to the ground, and the two men shot at the same time, destroying the two silver metal balls.

As soon as the two of them made a move, Xuanyuan Hong also moved, and suddenly appeared in front of the silver ball in a flash, and reached out and grabbed the silver ball, which had a round crystal side to the outside, but the silver metal ball had no way, and the power of flying outward could not break free from Xuanyuan Hong at all.

Xuanyuan Hong's other hand slapped on the silver metal ball, and the powerful force penetrated it, and the silver metal ball suddenly stopped moving, not making it immobile, but Xuanyuan Hong's power had destroyed its internal structure and completely destroyed the silver metal ball.

"Good job!" Xuanyuan Hong gave a thumbs up to his two subordinates, if he didn't have the help of two subordinates, it was not impossible for him to deal with the silver metal balls, but it would take a while, maybe he would have to risk being hit to get rid of them.

Xuanyuan Hong carefully checked the metal ball in his hand, it was very strange how the high-intensity laser came from, you must know that energy cannot be created out of nothing, the emission of the laser requires strong energy, and the silver metal ball is not large, not like how much energy can be stored inside.

After opening it, Xuanyuan Hong was a little dumbfounded, in the face of chips and lines, Xuanyuan Hong didn't understand, only professionals could understand it, right?

Xuanyuan Hong put away the three metal balls, presumably after taking them back, the military would buy them at a very high price.

No matter who gets it, if you study it thoroughly and master the manufacturing method, there will be thousands of metal balls, and even more and stronger weapons will be made according to the principle of metal balls.

The high price is for this reason, and it is worth paying a high price to be able to obtain unprecedented technology from metal balls.

In fact, there is already a precedent for discovering ancient technology entities and selling them at a high price, and it is not just one case, there are many people who have made a fortune because of this, Xuanyuan Hong has heard at least ten or more cases, and he knows that Xuanyuan Hong has the confidence to sell three metal spheres at a high price.

It's not that he's greedy for money, but that cultivation is an act of burning money, he doesn't belong to any family, no one provides him with the necessary cultivation resources, and without the necessary resource support, cultivation will be difficult, so he will always want to make money, which is actually to prepare for cultivation.

"Captain, there are traces of a battle ahead!" After continuing to move forward for a short time, Hong Liu made another discovery.
