It was just a few days after the formation of this special forces, that day, the team members were actively training, captain Wright was exercising the athletic ability of all parts of the body, "Hurricane" Bill was practicing running speed, "Agni" Jin was just practicing his hand and foot ability, "Computer" Kobo was holding a book and studying desperately, "Ability" Jamie was also constantly moving his body, suddenly with a crisp and rapid convening bell rang, and then, they urgently came to the command headquarters and met Dr. W.

As soon as the team members sat down, they saw Dr. W pick up a telegram from the table next to him, and eagerly said to the team members: "Soldiers, the evil forces of the World Terror Group have extended their claws to the whole world, and here is an urgent telegram sent by the authorities of City F. I saw that the word "urgent" was clearly printed on the top corner of the telegram, which had not yet completely dried.

Dr. W then said, "Recently, there has been a gang of masked gangsters in F City who are doing evil and have mysterious whereabouts. This gang of gangsters is stealthy, good at camouflage, and can urgently gather and flee. The authorities in City F have repeatedly dispatched military forces from all sides to round up and arrest them, but not only have they failed to catch a single terrorist gangster, but they have been confused by this gang of gangsters and do not know where they are. The authorities in City F are also very troubled and have nothing to do now. Some of the people in the city have been victimized, and some eyewitness evidence has been provided. After many speculations from the scene of the murder, this group of terrorist gangsters may be the advance army of the World Terrorist Group, and the Terrorist Group is likely to use this advance force to test the degree of reaction of countries around the world to this violent incident, so as to gradually extend its claws to the whole world. ”

At this critical juncture, the authorities of City F received an unsigned letter briefly describing an important feature of a terrorist who had been vaguely witnessed by one of the victims, who had an X-shaped logo carved into their arms, which according to those at the scene were associated with the World Terror Group.

The authorities of City F attach great importance to this clue, because it can be said that they have mastered the important characteristics of this gang of gangsters, but due to the lack of armament in the city, they have done evil against this gang of gangsters, and spread terrorist rumors such as the destruction of the world everywhere in the city, which has made the whole city panic and helpless to act all day long, and the people have no way to do anything about the behavior of the terrorists, which has made the whole city dark and chaotic.

"At this critical juncture," Dr. W then changed his tone in an excited and somewhat contemptuous tone, "just when the terrorists were rampant, Country M sent more than a dozen members of the anti-terrorist force to City F, and in just a few days, they wiped out this gang of gangsters. ”

During the search, it was found that all the arms of this gang of gangsters were engraved with X-shaped marks, which made it more certain that they were the advance team of the terrorist group, and then after repeated confessions, one of the gangsters finally confessed to the forward stronghold of the terrorist group --- the mysterious valley. Anti-terrorist forces were then dispatched, but after five days of unbearable waiting, only two of them survived and the others were nowhere to be found.

According to the memories of the two warriors who returned, before they set off, they had an inexplicable and faint premonition, which became stronger as they got closer to the mysterious valley. They recalled that while searching over the mysterious valley in a helicopter, the fuselage suddenly shook violently, and the electronic checker reported that it had been hit by an unidentified missile. During the emergency parachute jump, three fighters were "bulleted" to death, and then the helicopter exploded suddenly, and the rest of the fighters landed in this so-called "mysterious valley" after a forced landing.

Upon reaching the mysterious valley, the warriors began to search. As a result, for two days, they found nothing but the dense weeds in the valley and the trees that could not be seen as far as the eye could see.
