The Grand Canyon of Colorado, located in the Kaibab Plateau in northwestern Arizona, USA, has been the driving Colorado River from the Kampab Plateau in northern Arizona for hundreds of millions of years, cutting this amazing miracle - the Grand Canyon, it is one of the most magnificent scenery on the planet, welcoming five million visitors from all over the world every year, it is definitely the most noteworthy national park in the United States, and it is also the first choice for many travelers.

However, for unknown reasons, the Grand Canyon of Colorado, which had never been closed, was closed a month ago, and a large number of troops, armored legions, and groups of aerial fighters were stationed, flying by frequently.

In the desolate Grand Canyon of Colorado, there are huge round buildings with cement walls nearly 100 meters high, surrounded by military bases below, dozens of tanks and dozens of assault vehicles parked,...... , the military airfield reconnaissance aircraft group rises and falls, and the atmosphere appears very tense, as if war is coming.

The command room of the military base, a large monitoring screen, showing canyons, rivers, wastelands...... , hundreds of surveillance screens, monitoring the movement of a hundred miles around.

In the command room, General Ston's cheeks were sunken in the command position, and he was a little worse than he had been a month ago.

After the giant digging worm dived into the ground, a few days later, it lost its trace, and a month was about to pass in a blink of an eye, and a net was laid in a radius of hundreds of miles, however, the giant digging worm did not burrow out of the ground for a long time.

Could it be that Professor Manley was wrong, or had it already been out of the surface and hunting outside the surveillance zone?

If the digging insect grows and develops in the direction predicted by Zhou Xing, it will evolve into a mother worm and develop a swarm, which will pose an extinct threat to human civilization.

As time passed, the pressure on General Stone's heart increased day by day.

With a gloomy face, General Ston looked at the command platform and asked, "Did you find anything unusual?" ”

"There are no anomalous phenomena in surveillance areas A1-A5. ”

"There are no anomalies in Zones B1-B7. ”

"General, there is an anomaly in the C1 surveillance area, and the image of the IT23 wild deer herd has been lost, and the other areas are normal. ”

"The deer herd of IT23 was found in D2 and there is no anomalous imagination in D1-D6. ”

“……。 ”

Hearing General Stone's inquiry, the monitors in front of the big screen replied one after another.

Soon, a look of disappointment appeared in General Ston's eyes, and there was no special anomaly?

When everyone finished their debriefings, a somewhat hesitant voice added: "General, the N surveillance team has discovered a special situation here, but it will take time to verify. ”

"What's the situation? General Ston looked at the watchman and asked urgently.

"General, there is an anomaly in the movement of the FE crocodile swarm. The monitor turned to General Ston and reported.

"Hmm, what's the anomaly?" asked General Ston excitedly.

"General, crocodiles are cold-blooded animals, after spending the night, their body temperature is low, blood circulation is slow, their limbs are slow to respond to nerve commands, and their eyesight is blurred at this time, they generally bask in the sun in the morning, and through the sun, their body temperature rises, prompting all parts of the body to return to normal; The watchman looked at General Ston and explained.

Hearing this, General Ston flashed brightly, looked at his subordinates beside him, and ordered loudly: "The marines are dispatched to strengthen the search in Area F." ”

"Obey, General. "The officer commanded.

Soon, the brigade rushed out of the military base and went straight to the surveillance area of Area F.

General Ston couldn't wait to leave the base command room and rush to the lab's manufacturing room.

In the laboratory manufacturing room, a large group of technical experts and more than 50 people are debugging and installing a bullet-shaped equipment, some verifying data, some welding components, some testing systems, and some proofreading drawings,......。 Concentrate on doing what you are doing, and you are busy on the spot.

The bullet-type equipment is like the head of a moving car, about ten meters long, two meters high, with a black strip attached to the bottom, its head is tapered, smooth as a mirror, exuding a bright silver metallic luster, the core head is obviously completed, the fuselage is completed or so about seven layers, they are working intensively, and no one notices the arrival of General Ston.

"Li, how long is it going to be done with this drilling rig?" General Ston went directly to the project leader, a Chinese man with gold-rimmed glasses.

"General, ninety percent of the overall project has been carried out, and it will take two days for the final peripheral installation and final commissioning!" the Chinese man turned his head to General Ston and introduced with a smile.

"Okay, aren't you Mr. Zhou here?" General Ston's eyes lit up, and he looked around, but he didn't find Zhou Xing's figure.

"No! He's not coming over until the work is over, and he's probably going to another manufacturing room. The Chinese man shook his head and guessed.

General Ston nodded, and immediately said goodbye to the Chinese man and hurried to another manufacturing workshop.

Soon, General Ston arrives at another fabrication shop, where Dr. Manley and a group of his subordinates are busy around a giant ring-like instrument.

The circular giant ring is more than six meters high, and the exposed wire rings are covered with dense induction chips, large and small, filled with thousands of lines, which makes people's scalp tingle.

General Ston walked up to Professor Manley and asked, "Professor, how's the progress of the biodetector?"

"Everything is going well. Professor Manley stopped what he was doing and nodded excitedly.

Hearing this, General Ston looked at the complex instrument in his eyes, and asked in surprise, "Haven't you encountered any difficulties until now?"

Professor Manley looked at General Ston with a complicated expression, and asked with emotion: "According to his design drawings, there is no problem at all, which is very powerful!"

General Ston nodded blankly, and looked at Professor Manley puzzledly: "How did Zhou do it? Could it be that he had already built this piece of equipment before this? Otherwise, it would not be possible to succeed at one time!"

Professor Manli smiled bitterly and introduced: "General, if this equipment is not for dealing with that giant digging worm, it will be useless at all, and no one will spend such a big price to make such a device, so this equipment should be designed by Zhou Xing for the first time." ”

"But, this is incredible!," said General Ston, opening his mouth, still incredulous.

"I couldn't accept this situation at first, but the truth is, Zhou, he's such a genius. Professor Manley said with a wry smile.

Thinking about Zhou Xing's previous deeds, General Ston took a deep breath and nodded to accept this fact. 20110
