The big sword in the hand of the fortress mecha and the big sword in the hand of the demon collided violently, and after a loud bang, the powerful energy spread out in all directions, and some low bushes could not withstand the invasion of the strong wind, and were blown to pieces, falling to the ground in pieces.

The two sides did not immediately separate from each other in a one-hit fight, but entered a state of wrestling. This is exactly what the general on the fortress mech wants to happen, only then will the antimatter energy sword have the possibility of destroying the broadsword in the demon's hand.

"Immediately increase the energy output and destroy the weapon in the demon's hand!" the general saw that he could not miss the opportunity and immediately ordered. Immediately, the big sword in the hands of the fortress mecha began to ripple with energy, and the entire sword body became red, and the big sword in the demon's hand cracked in the state of the giant sword's energy increase, and then began to collapse!

Taking advantage of this momentum, the Stronghold Mecha once again increased its energy output. At this moment, the big sword in the demon's hand couldn't withstand the huge pressure, and collapsed instantly, and the big sword in the hand of the fortress mecha took advantage of the situation to slash down with all its might, and cut off the head of the giant demon with a single sword, and the giant demon collapsed into invisibility.

The process of slaying the demon was unexpectedly simple, and the generals and team members in the fortress mecha thought it was strange, could it be that this demon only had a huge size and no strength?" The general sat back in his large chair and took a sip from the glass on the small table beside him.

"General, that demon has reappeared!" the observer saw the disappeared demon reappear, and he immediately reported it to the general.

The general, who had not yet sat down, immediately stood up when he heard the report and hurried to the display screen, sure enough. The demon that had been destroyed slowly rose from the ground and soon regained its original form!

"Attack, destroy it!" the general looked a little bad. Viciously ordered the mech to attack. The fortress mecha that had just stopped immediately activated, and it was a few steps in front of the demon. The big sword in his hand slashed with all his might. This time, the demon didn't take the sword hard, he just dodged the sword blow sideways, and the big knife in his hand slashed horizontally, straight to the waist of the fortress mecha.

The Fortress Mecha has a complete motion capture and reaction mechanism, and when the attack comes, the Mecha immediately swings its sword to block and block the fatal blow. The demon's broadsword was flicked away, and it roared angrily, and the broadsword in its hand slashed down again. The energy detector on the mech immediately detected it. Since the opponent's strength was very strong, the fortress mecha immediately took a dodge, and the huge mech jumped backwards, dodging the demon's broadsword.

At the moment when the fortress mecha jumped backwards, the demon's chaotic eyes flickered, and the movement was extremely fast and started to crash into the fortress mecha, if it was really hit, the fortress mecha was very likely to be hit by the demon's big sword before it had time to get up!

"Turn on the jet engine immediately and let the mech fly!" the general ordered as the mech jumped back. It was at this time that the demon savagely crashed into it. At the last moment, the fortress mecha instantly soared into the sky, dodging the impact of the demon.

The demon who had lost his purpose looked up. Looking at the fortress mecha in mid-air, it let out an explosive roar, and the demonic wings behind it flapped violently, and its huge body soared into the sky at an incredible speed. Pounce on the Stronghold Mech.

"Transform the flight battle mode. The deputy commander made a quick decision, judging by the speed of the demon. Stronghold Mechs will be passive if they don't change form. The mecha crew received the order and immediately went into action. The fortress mech quickly deformed after violently accelerating to distance itself from the demon, and soon became a large aerial battleship, with various ranged weapons ready to go.

The distance that had just been opened was quickly pulled close under the rapid speed of the demon, but the mecha had been transformed, and under the order of the general, the speed of the mecha also increased rapidly, and at the same time, missiles, shells, lasers and other weapons were fired at the same time, and the demons in flight were constantly hit, and the speed of flight was greatly reduced.

"Fire the main cannon and defeat the demon!" The general was already sure of victory at this time, and it was impossible for the demon to survive and regenerate under the bombardment of the antimatter energy cannon. He sat back in his chair and leisurely watched the demon be destroyed.

Directly in front of the exterior of the mecha battleship, a huge black cylinder slowly stretched out, and a faint orange substance was churning inside, and a terrifying energy was brewing. The accumulation of huge energy simultaneously caused changes in the surrounding air, and a pitch-black cloud formed at a speed visible to the naked eye. This is a special phenomenon that will occur when the antimatter energy cannon is about to be launched, which is why the antimatter energy cannon is also known as the "Thor Cannon".

The strange changes in front of him did not stop the demon's flight trajectory in the slightest, and it still pounced quickly towards the mecha battleship. "I don't know if I'm alive or dead. The general sneered and said, "All attention, fire a cannon for our demon friends." ”

Following the general's order, the operator of the antimatter energy cannon turned on the safety and pressed the firing button. I saw a flash of orange light visible to the naked eye but not dazzling, followed by a continuous roar of rolling thunder. The demon hit by the antimatter energy cannon seemed to be frozen in the air, and in the next second, the giant demon collapsed into the air again.

"I don't believe it can be regenerated. "The general is very proud, although the demon is very strong, but it is not vulnerable to strong weapons. But just as the general was about to order the mecha battleship to descend, the figure of the giant demon unexpectedly appeared on the ground again!

"What's going on?!!This can't be!" the general's mouth opened in surprise, he couldn't believe that the demon could be reborn under the antimatter energy cannon!

"I seem to get some of it, Shogun. The deputy commander's voice suddenly sounded, and he vaguely felt that there was something wrong with this demon that could not be killed.

"What? what have you discovered?" the general hurriedly asked, "Is there anything special about this demon?"

"I don't think this demon is a physical demon, it should be a combination of energy, that is to say, this is a rare huge demon soul formed by countless tiny demon souls, and because of its extremely strong energy, it already has the ability to attack independently!"

"Is there any way to deal with it?" the general didn't want to know the origin of this demon, he just wanted to know how to deal with this huge demon-like soul.

"There is a way, the core power of our mecha is to use the Demon Crystal Array Group to provide power, as long as we can control this huge Demon Soul in the power core of the mecha, it will lose its threat and provide us with objective energy!"

"Very good, all the technicians immediately analyze the feasibility of controlling the demon's soul, we can't let go of this once-in-a-lifetime opportunity!" The general waved his hand and handed over the problem to his subordinates, he stared at the huge demon on the display, and the sneer on the corner of his mouth became more and more ......eerie.
