Placing the boxes one by one on the floating car that Qiu Long was driving on, Si Xingfeng asked, "Where did you get the broken car?" ”

Seeing him look at his valuable classic car with deep suspicion, Qiu Long was reluctant, "Brother Feng, this is not a broken car!" It's an antique! ”

"Antiques?" Si Xingfeng still had a look of disdain in his eyes, "The body is old, the paint is faded, and the armor is not thick, according to the time you came, I estimate that its speed should not be fast enough......"

Qiu Long looked at him, and made up the words he didn't say, "Isn't this a?" However, he definitely disagreed with Si Xingfeng, "Brother Feng, this car is a classic of Kelanda!" One of the best and most popular floating cars from over a hundred years ago! ”

"I'm afraid you're not kidding me, the Kelanda consortium itself has been bankrupt for decades, and it's really hard for you to find it out!" Si Xingfeng exclaimed.

"That's not it, I've been practicing for half a month!" Qiu Long said proudly.

"But it's a piece of now!"

"Brother Feng, you can't judge the car by its appearance, when I change it to a beautiful armor, it will be like a new car!"

"Qiuqiu, I don't have any talent for firearms, but I still know a little about this car!" Si Xingfeng looked around the car, "Although the floating system is intact, the BTX series floating module used in the car a hundred years ago consumes serious energy, not to mention that it can only maintain ultra-low-altitude flight, which has great limitations!" Since you say that it is a classic Colanda, then its core power should still be the old composite nuclear power steam internal combustion engine, which has the advantage of having an energy conversion rate of more than 80, but has a fatal drawback, that is, this internal combustion engine is very unstable. It is precisely because of this that the originally well-rated Klanda consortium gradually withdrew from the stage of history due to several successive internal combustion engine explosions! ”

Qiu Long nodded, "Brother Feng, I know you read a lot, but sometimes the things in the books are not all right. ”

Si Xingfeng was skeptical, "What do you say?" ”

"The founder of the Kelanda Group, Ke Lan. Dadal is a genius mechanic, but he's not a good businessman! Qiu Long opened the door and jumped into the poison dragon car, "Not to mention the floating module of the BTX series, it is indeed not good. But the CJH internal combustion engine developed by Mr. Ke Lan is obviously underestimated by the whole era! ”

Turning on the start button, Qiu Long also made the internal combustion engine of the floating car move, "This internal combustion engine adopts a composite mode of nuclear power and steam power, which is absolutely genius, and it should be able to improve stability and energy conversion rate at the same time!" The explosion of the internal combustion engine you mentioned was entirely caused by the fact that he was designed by his peers, because there was a problem on the supply side of the energy block! ”

"Really?" Si Xingfeng still couldn't believe it.

"Really, this car is a prototype car, so I never used the energy block, so I just discovered the problem when I tried to restore it." Qiu Long sighed, "It's a pity that the internal structure of the internal combustion engine of several other cars excavated at the same time in the ruins has been destroyed, otherwise, I would definitely be able to deduce the design of this internal combustion engine in reverse." ”

"Do you think that its internal combustion engine is stronger than the YHX series, which is the most popular in our fortress right now?" Si Xingfeng asked, "This is a gap in science and technology that has been a hundred years apart!" ”

"Brother Feng, it's not right for you to think so!" Qiu Long shook his head, "It has been more than a thousand years since the invention of the steam engine, and the smelting technology of steel has been more than three thousand years, but in fact, we have not made full progress in many processes!" ”

"Also, even the best-performing YHX-VIII. internal combustion engine seems to have an energy conversion rate of only about 78." Si Xingfeng nodded.

"In fact, the conversion rate is secondary, mainly because the internal combustion engine invented by Mr. Ke Lan has an irreplaceable advantage! It only needs to use energy blocks with a purity of three levels, and most of the current internal combustion engines use energy blocks of more than five levels, which is too much difference in cost. Qiu Long said with emotion.

"Qiuqiu, you just said that this float was dug up from the ruins?"

"That's right, it's the remains of the Beibu Bay, where there is the ruins of a floating city that fell hundreds of years ago! The cars were found in a floating car shop in the city. ”

"Huh?" Si Xingfeng made a puzzled voice, "No, Kelanda has only been established for more than a hundred years, how can this brand of floating car appear in the ruins of Beibu Bay?" Moreover, it stands to reason that the armor metal of the floating car will not decay like this in just a hundred years, right? ”

"It's not good, time and space rewind!" Qiu Long exclaimed, "Brother Feng, get in the car, there must have been a time and space backtracking in Beibu Bay." Hurry up and call the Qingqing Fairy and ask her to tell Grandpa Gu to let the exploration army of Beibu Gulf be careful of encountering the time and space tunnel! ”

Although he didn't quite understand what he meant by time and space regression, Qiu Long still turned into the car and conveyed the words to Gu Qingqing.

Hanging up the hair communicator, Si Xingfeng tilted his head to look at Qiu Long, who was driving a floating car frantically, and stopped talking.

"Brother Feng, the time and space regression is a bit similar to a mirage, but everything in the time and space regression is real." Qiu Long explained, "I don't know what to say, you should know the concept of time travel, but time travel has never been proven, but time travel is real!" Let's say something that existed for 2,800 years ago would suddenly go back much further, maybe 2,000 or 2,400 years! ”

"Kind of like a glance for ten thousand years?" Si Xingfeng asked tentatively.

"Almost, as if we once recorded in history, a brand-new lighter was found in the ancient tomb of the Qin Dynasty. Or maybe something around you suddenly can't be found, but it suddenly appears in front of you, it's a phenomenon of time and space regression! ”

"Really, fake?"

"I also heard my uncle mention it, and I thought it was amazing, so I wrote it down." Qiu Long asked suspiciously, "Brother Feng, haven't you seen it in the library?" ”

"Nope." Si Xingfeng shook his head, "There seem to be a lot of things missing in the Dongting Library, and even the things recorded in many books still have many contradictions, but I have never heard of the ranking of time and space regression. ”

"Listening to my uncle, the space-time regression itself is nothing, it only affects non-living forms, but some of the special phenomena that accompany the time-space regression are different, and any living form that strays into it will be instantly lost in the turbulence of time and space." Qiu Long drove the float out of the fortress gate and rushed directly towards the Gulf of Tonkin Bay. "Right now, I'm worried that there are still space-time tunnels or space-time traps there, and then the exploration team ahead will be very dangerous."

"Nani?" Si Xingfeng's mind instantly became a little confused, and he began to mumble in his heart. "Could it be that I came here through a time tunnel? The power of time and space is so amazing? There is also the mysterious lost city, which seems to have undergone strange changes due to the effect of time and space. ”

"But is it too late for us to rush over, Commander Gu must be faster than us, right?" Si Xingfeng asked Qiu Longhe.

"The problem is that we don't know if Grandpa Gu has time now! Shortly after I gave him a sword in the morning, he went to the front, where it was said that an army had been attacked by the Xenomorph Legion, and suffered heavy casualties. Qiu Long sighed.

"What about Uncle Ning?" Si Xingfeng prompted. "Can't your uncle reach them?"

"Don't mention it, my uncle's communicator has always been unreachable." Qiu Long hurriedly stopped the car, "Only he is looking for others, but others can't find him." But you reminded me that I can call Instructor Lei Li directly! ”

"Instructor Lei Li?"

"yes, you don't know yet! Among the several teams responsible for exploring the ruins of Beibu Gulf happens to be his black locust team. Qiu Long said as he looked up Instructor Lei Li's contact information.

With a sigh in his heart, Si Xingfeng suddenly worried about the straightforward men who had taken more care of him for no reason. What Si Xingfeng has to admit is that he sometimes has a bit of a back, and people who are close to him sometimes invisibly get some bad luck.

The female warrior of the bear tribe who saved her at the beginning, her savage nurse Xiong Lan, is still missing.

Ergou, his adoptive father Xiao Cong and Teacher Gu Qi, who entered the lost city with him, either died tragically or were also trapped in the city and could not get out.

Even Liuli, who happened to meet with her in the assessment not long ago, also experienced radiation damage with herself, but fortunately, she was in danger and there was no big problem.

As for now, is it Instructor Leili's turn......

Under Si Xingfeng's expectant gaze, the other party finally connected to Qiu Longhe's communication application.

"Instructor!"

"Well, it's good that you're still here, Brother Feng and I suddenly found that there was something wrong with the floating car you unearthed before. We suspect that there should be no time and space regression in the Gulf of Tonkin to know when! ”

"Yes, yes, so you have to be careful of the existence of space-time tunnels and space-time traps!"

"Okay, then I won't bother you, goodbye instructor!"

Hanging up the communicator, Qiu Long also breathed a sigh of relief, "It's okay, it's a false alarm!" The instructors said that they had not found any problems yet, and that they would be more careful. ”

"That's good, that's good!" Si Xingfeng also relieved himself, "Then let's go to the academy to pick a dormitory." ”

"Didi...... Before Didi...... voice fell, Gu Qingqing's call application came from his communicator.

"Hey, Qingqing, what's wrong?"

"I've already told my grandfather, the exploration team ahead should have received the news!" Gu Qingqing said, "I'm going to tell you a secret!" ”

"What's wrong?"

"When I was talking to my grandfather, I heard a very heavy fight, and a very heavy sound of gunfire. I have a hunch that a big war is about to break out! ”

Si Xingfeng was silent, in fact, since he came to the Far Eastern Fortress, he knew that a war would break out here sooner or later. It's just that Gu Qingqing's words still hit a very soft corner of his heart.

He knew very well that war was not a game, and there was never a right or wrong. He had dreamed for a thousand years, so he knew very well that war would kill many, many people!

Even if everyone said that glory was cast with blood and fire, when he thought that the fresh lives were quickly harvested like wheat, Si Xingfeng did not have the pride and enthusiasm to make meritorious achievements, but a great fear surged in his heart.
