It took a lot of effort to coax Tang Xu off the plane. Tang Jin only hurriedly replied to a letter from Khan Meng, saying that he had arrived safely, and was dragged by the impatient Tang Xu to explain the operation method.

Fortunately, the operation of the gyroplane is simple, and Tang Xu himself is also very smart, after only two days of explanation, Tang Xu mastered the general flying skills, and then this guy impatiently drove the plane up to the sky.

Of course, this heaven is just what he thinks he is going to heaven, and the total flight altitude does not exceed five floors, at most it can be regarded as barely taking off, but even so Tang Xu is already very excited, the whole person is shouting in the sky, if it is not for the need to grasp the control stick with both hands, this guy is afraid that he will be able to dance happily.

Being able to land and take off freely means that Tang Xu has basically mastered the flight method, and the rest is only to rely on constant familiarization and practice. At this point, Tang Jin had no doubt about the enthusiasm of this product, obviously it only flew less than five stories high, but the whole thing was still extremely hilarious, and it even pulled Tang Jin to chat all day. The approximate sentence is "You know how high you can fly ......"

Tang Jin could only echo helplessly, but at the same time said in his heart: "The master has not flown over thousands of meters in the air without such a rich feeling as you, you are simply condescending to be a poet when you don't go away." ”

"Okay, I've taught you how to fly a plane, I want to play by myself, I still have business, don't bother me." After that, Tang Jin turned his head and left. He still has to think about when to attack the north line, so do you have time to fight him? If it weren't for the fear that this thing would make an accident with the plane himself, Tang Jin would not have found two days to teach him.

Returning to the study again, picking up the telegram stacked on the table, Tang Jin took out a new map and marked it on it. After finishing the matter, he hung it next to the map that had been marked before, and Tang Jin frowned and looked at the two maps that were not abnormally obvious.

The old one was drawn by him two days ago based on the telegram sent back from the front, and the new one is the latest, and according to the intelligence, the overall battle situation is not optimistic.

Xu has not had a major battle for many years, and his armament has been relaxed. In the four lines of defense, except for their own

Except for the northeast defense line, the remaining three places have either been completely unable to hold up, or have been broken through, or have turned from the original offensive into a stalemate.

Undoubtedly, the recruits led by a group of noble children still can't resist even if they are facing a weak barbarian tribe, but fortunately, the barbarian tribe that is being repelled is limited to this, and the legions that have repelled the Tang Dynasty themselves have no strength to attack; Needless to say, it was naturally the northwest defense line, and I don't know if I felt that the previous national pillar ran away and relatively damaged my own troops, and the rest of the national pillars also withdrew their troops one after another, directly surrendering the entire border city to the barbarians.

"These bastards...... What about returning the national pillar...... Moth-eaten bar! Tang Jin looked at the red Northwest Defense Line and complained helplessly.

The rest is the west defense line, the west defense line is the only defense line that still maintains an offensive posture except for Tang Jin here, and now the attack has stopped, and the two sides have entered a stalemate, and in the stalemate, Datang's side is not dominant, and there is a high probability that it will be chosen to retreat.

"Damn, didn't Tang Yu think about this before the fight? If it weren't for the fact that the master was quite reliable here, this expedition would have become a joke. Tang Jin covered his forehead and complained helplessly.

In fact, Tang Yu didn't think about this, but he miscalculated the situation. In terms of overall strength, Datang is not to say that it is compared with the hinterland barbarians, but it is definitely much stronger than the scattered tribes around it, and there is basically no possibility that it cannot be defeated.

But this is only an advantage at the data level, and the situation is different when it comes to fighting. Take a few national pillars as an example, if the legions under their command go all out, it is not a problem to face three or four tribes at the same time, but now they have been beaten back again and again, can't they be defeated? Of course not, it's just that they don't want to fight, and they don't dare to fight, just to protect their own interests.

In this regard, Tang Jin has always been curious about one thing. If the Tang Dynasty was captured by the barbarians, what was the use of the troops under their hands, no matter how strong they were? The court is gone, what power do you have? The power of the barbarian tribes? I'm afraid that people won't kill you directly.

Let's talk about the veterans of the due west line. Yes, they are

It's experienced and the cooperation of his soldiers is also very tacit.,But they're good at defending the city rather than siege warfare.,At first, they can rely on the knowledge in the war book to support it.,But the war book is always half useful and half nonsense.,The more you go on, the more weak it becomes.。 In addition, when he is old and lacks the sharpness of the year, it is inevitable that there will be restrictions when he fights, so it has become the current passive defensive situation. Fortunately, the old guys really have a way of defending the city, even if they use the playful city walls of the barbarians, they can resist the back and forth impact of tens of thousands of people on the opposite side.

To sum up, there is a very strange scene now, it is clear that Datang is much stronger than the barbarians in terms of overall strength, but it is defeated and retreated. The only advantage is still based on Tang Jin's opening.

"Forget it, no matter, since you're already involved, you have to do your best to do it anyway." Thinking like this, Tang Jin approached the map and began to carefully study the route of the march.

The production of military vehicles and aircraft on the side of the Khan and Meng tribes has been put on the agenda, and it only takes about half a month to barely meet Tang Jin's needs, and if you want to fight a quick war, you have to plan well, if there is a little negligence that causes the blitzkrieg to become a protracted war, what is the result...... Refer to Germany during World War II.

Tang Jin's side was making plans, and the others were not idle. After Tang Xu was proficient in flying the plane, Tang Jin gave him the task of training pilots; Qin Hai is still in charge of the daily training of the artillery regiment; Fang Xiaoer is in charge of intelligence gathering and logistics; Feng Gu mainly ran back and forth between the various tribes, recruiting new recruits while finishing the rebellion plan.

Yes, in order to be able to attack the northern defense line and even the northwest defense line well, Tang Jin must expand his army, otherwise relying on the 10,000 people in his hand, unless he can create a "Katyusha", it will be absolutely useless.

In this way, half a month passed in a hurry. Tang Jin's long-awaited journey to the north kicked off, and this moment also left a strong mark in the history of later generations. It was from this day that Tang Jin's name began to resound throughout the continent, and later generations called this day "the day when the hidden dragon came out of the abyss, and the heaven and earth fell!" ”
