After relief threatens, the unmanned machine arrives at 51 areas to pass in and out underground research area of entrance.The entrance at this time is very confusion, because the underground research area reason happened unidentified greatly explosion, have already destroyed a lot of laboratories.Continue foolish in the underground already insecurity, the survivors all at broadcast of remind under quickly withdraw here, some withdraw early person have already driven vehicle to leave this base. The Yan flies the researchers who didn't take care of to leave, he drives unmanned machine to fly to exit and entrance sky, the machine stomach of unmanned machine opens, a type gbu-28 with huge body figure laser guidance bomb blast-off goes out, and the passage of facing underneath flies.Open in the unmanned machine machine stomach for an instant, the movements of unmanned machine is brief drive rice soldier the radar target, but wait until unmanned machine machine stomach to close, the target of rice soldier radar disappears to be missing …… The type gbu-28 laser guidance bomb is unmanned machine power to strongly drill a ground of bomb, a weight comes to a many 23 tons, is unmanned machine power biggest attack weapon.However the Yan flies have been all seldom using this kind of big power bomb, because he hardly meets the target that needs to drill a ground of attack.He wants to destroy 51 areas of being located in the underground 200 meters deep place now, this kind of power strongly drills a ground of bomb be had better choose. Under the precise operation of the guide line and assistance Zhi brain of quantum radar, this laser guidance bomb perpendicularity shoots the exit and entrance of 51 areas, however this laser guidance bomb didn't like other bomb the occurrence explode, but break open a strong and tough ground to drill ground downward right away and wait until a laser guidance bomb to drill a ground 100 meters of time, its delay fuse just be stired up, then take place violent explosion, 100 meter deep place all of the building of the neighborhood destroy.And the impact wave of this explosion is also anti- to hurtle up the ground, exit and entrance passage the neighborhood didn't in time withdraw of all of the research personnel kills by explosion. The type gbu-28 laser guidance bomb drilled ground to come to a 100 meters for the first time deep, because it drills the place of ground is the elevator that the rice the people builds to ascend and descend well, in have in great quantities hollow space, so would obtain to like this and well drill effect.Immediately after the Yan flew to shoot the second type gbu-28 laser guidance bomb, this laser guidance bomb along the passage that before develops continues to drill ground downward, however this of drill effect isn't very good, just drilled ground downward 60 meters.After waiting until Yan to fly to shoot the third type gbu-28 laser guidance bomb, this laser guidance bomb just arrives at the underground of 200 meters deep place and destroys a great deal of research center of underneath. The scope of 51 area overlays is very huge, each research building saw have a hard insulation equipments, even if the Yan flew to destroy an among those important district, but could not arouse large chain reaction and destroyed all of the whole 51 areases. The Yan flies to also understand this truth, hence his change attackstones a target and start attackstoning Be one kilometer ground apart from the exit and entrance.In the scanning of quantum radar, the Yan flies to know 100 meters the deep place contains a lot of large buildings at the underground, there is still a great deal of researcher's existence in the building.The Yan flies underground of knowing the 200 meters deep place not to have what important thing, but have so many research personnels in the 100 meters deep place, already worth he carries on attackstoning to here. A type gbu-28 laser guidance bomb shoots a desert earth's surface and gets down to quickly drill ground.There isn't any hollow elevator well here, so when the type gbu-28 laser guidance bomb gets into the underground 80 meters place, violent explosion happen.However be apart from 100 meters to still have a distance here, have no the research center to the 100 meters deep place and personnel to result in dead and injured.However the second type gbu-28 laser guidance bomb then drilled the depth of 140 meters, the aftermath of explosion pounded at the research organization and personnel of 100 meters deep place, research the personnel in great quantities kill wound. Connect down Yan to fly again shoot two type gbu-28 laser guidance bombs, just finally arrive at 200 meters deep place, destroy a great deal of research building of underneath. After exterminating this target, Yan's flying is just preparing to convert an attack target, discover that the underground of 200 meters deep place look like some different places.Before be destroyed of in the underground, is all wild red flame and thick smoke everywhere.But in this underground, appear of but is a blue mysterious ray of light, that originally should red flame and thick smoke appearing don't know that is eventually. The Yan flies heart in curious, discover blue ray of light being more and more prosperous, then a mysterious aircraft that all over sends out blue light quickly fly out from drill a ground of huge tunnel that the bomb deep-fries, then a hasty brake, hang to stop like this at Be 200 meters apart from the ground of midair. After discovering the aircraft that can hang to stop, the Yan flies very shocked.Because he discovers this aircraft body figure it's very huge, incredibly more even big than unmanned machine shapes b-2s.This aircraft display of is a kind of special streamlined and aerodynamicist shape, still have never seen from other Earth aircrafts before Yan fly. However the Yan flew to discover a familiar place right away, that be the machine body color of this mysterious aircraft body ash black, have some the inclination angle of the places and the shapes b-2s of the rice soldier completely consistent.If expel different spirit of this mysterious aircraft to move shape, it actually and the b-2 of the rice soldier the invisible bomber have quite a few of the place of likeness, the b-2 of rice soldier should be the design inspiration that acquires from this mysterious aircraft. Then the Yan fly and then discover an affair, that is this mysterious aircraft to also have violent radar invisible ability, common radar basically detection not it.This invisible ability should with its machine body the design and packs of ash the black material is relevant, in view of this, mysterious aircraft and the connection of b-2 are very strong, almost a died to printout come of. However the b-2 of this mysterious aircraft and rice soldier has a lot of different places again, for example its machine body outwardly sends forth a blue ray of light, this kind of blue ray of light covers with it at in, look to have a science fiction color very much.And this mysterious aircraft still owns to fly unmanned machine to similarly hang the ability of stopping with Yan, can easily hang to stop in mid air. Just the first sees to see this mysterious aircraft, the Yan flew and then discovered its remarkable.The science and technology content of this mysterious aircraft is very high, have already exceeded the science and technology level of rice country very obviously.The Yan flies an emissive type gbu-28 laser guidance bomb's underground explosion in 200 meters deep place could not hurt to this aircraft just, explain this aircraft very hard. Then the Yan fly to think of if the China captain and oneself once said, that is the rice the people and discover 100 by several decades Mu the bottom of sea square of the big triangle region of time, they once found out an aircraft of integrity from that bottom of sea square and also to bring back that aircraft rice country.Now looks, this mysterious aircraft should be the the that the rice country gets from the bottom of sea square. The rice country is a to be carrying on a research to this mysterious aircraft, then they designed according to the research achievement the b-2 of the rice most advanced country invisible bomber.However is very obvious BE, the b-2 of rice the people makes copy to not succeed, their imitations and original article are compared with to differ too far. This mysterious aircraft owns radar invisible ability, however this invisible ability and b-2 together root together source.The unmanned machine quantum radar that the Yan flies can easily discover the b-2 of rice soldier, so natural can discover this mysterious fighter jet, its invisible ability flies to the Yan invalid.And the only differentiation of b-2 be, the unmanned machine targets the energy point that this mysterious aircraft needs to be consumed to have to be much some. After discovering from the mysterious aircraft of 51 area take-offs, the Yan flies to feel strong threat right away, he has no hesitant of shoot toward the other party an air-to-air missiles ai-120s to carry on an attack to sound out. That mysterious aircraft seem wrong, it suspends in mid air like this, the machine body still and just and continuously flutters to revolve, the pilot who is like an inside is beyond control it similar.While facing to strike guided missile, it has never done to serve as what of avoid being seen action.
