The air raid on the roof of the world was not known to the outside world, and the two elite armies of the Japanese army moved towards the mountain pass where Tso Na and Yadong were located, and the British army stopped Li Lu from defending the Indian line overnight, but they did not know that the Japanese army had jumped over the wall at this time.

Dongku's side is very stable, and Mongolia has seized the time to install a de-icing system, an oxygen supply system, and a heating system for the plane returning to pull supplies, but these are only to Yushu, and they cannot fly safely to Lhasa.

They can only be used as convoys.

At the same time, the workshop plant stepped up the production of real anti-icing, de-icing helicopters, and added an already shrunken radar as a test. These are the planes that can really cross the Hump Plateau like the previous 200 planes.

Dong Ku's side of the intense preparations, as soon as dawn, the first batch of 30 planes ready, escorted by only 10 attack planes, to clean up the new air defense facilities that may be erected, the second wave of planes took off half an hour later, just in time for the end of the first batch of bombing, and then it can be extended, an hour later, between the morning and 2 pm, the uninterrupted air raids, so that the Japanese army did not even have a chance to arrange and build defenses.

The army advanced to Qinghai Lake again, went straight to Qinghai Lake, and continued to adapt to training. Judging by the current reaction, they have another week and will be ready to go.

The planes took off in Xining, because only here are oil barrels and ammunition reserves, Yushu is only a temporary airfield, and the supplies are in Xining.

The leader of the team was a veteran pilot of the Northeast Army named Zhang Bingkun, who was the first batch of old men who joined the advance army in Weihu Mountain. Although he is a little older, he is extremely calm and experienced, and he has followed the advance army for the longest time. Now he is a team leader.

As the first batch of bombing teams today, he was more cautious. He knew that whether he could bomb safely in the future depended on whether he swept away the anti-aircraft weapons erected by the Japanese army in the first wave.

The group roared into the sky and headed straight for the jade tree. From there, they spoke straight to Naqu. Then attacked Lhasa, following the route of the previous flight.

In the sky, it was clear and cloudless, and the group of planes flew high in the sky, looking down on the white mountains below, and the line of sight was extremely broad.

Just when he was about to approach Yushu, he had already made contact with the ground and was about to rise directly and fly towards Naqu. Zhang Bingkun suddenly felt the fuselage shake, and then it was bumpy.

"Enter the chaotic air flow at high altitude, pay attention to the crews, and keep in formation!"

He calmly gave orders, controlling the bumpy plane.

The group of planes all entered the chaotic air current, shaking one by one, and continued to fly firmly towards Yushu.

As we got closer and closer to the jade tree, clouds slowly appeared in the sky. It was no longer clear for a few minutes, although I could still see the course. But the view has been blocked.

"Lower your height and get closer to Yushu! Get ready to land! ”

Feeling the vibration of the fuselage getting bigger and bigger, Zhang Bingkun was beautiful and careless. He knew that the appearance of the upper-air currents in the Dao was the beginning of the change of the sky, and it was a normal phenomenon of air currents.

After he gave the order, he contacted Yushu, which was close at hand. Prepare to land.

Yushu quickly dispatched airport personnel, prepared searchlights and smoke, and prepared for the landing.

The plane was jolting, and it slowly approached Yushu in the growing wind, and the dust was already hanging on the ground. Landed smoothly at Yushu Temporary Airport, and quickly took windproof measures.

After the last plane made a dangerous landing, Zhang Bingkun rushed to the base in the face of strong winds that had already reached level six or seven.

Dong Ku soon received the news that the first batch of air raids could not be carried out and that strong winds blocked flights. He didn't have an aunt, so he gave Zhang Bingkun an order to protect him and wait for the weather to clear in Yushu.

He does not have a weather forecasting system, although he can easily predict the surroundings, but it is impossible to predict the extent of long-distance prediction, after all, there are no meteorological satellites, and only balloons can know the approximate subsequent changes around the tunnel.

The plateau is changeable after that, and he knows the way, which is why he doesn't care.

The stronger the wind and the moon, Yushu has reached the appearance of seven or eight levels, and it is impossible to take off, and after waiting for two hours, Zhang Bingkun came to the judgment that the air raid will not be done today.

Yu Lei's adaptation training also had to be terminated, and in the strong wind, he couldn't do anything except hide in a sheltered place to keep warm.

The wind was still intensifying, and the army that had advanced into the Qinghai Lake returned in the fierce wind. The winds had already reached the area, and they had to stop their acclimatization and return to their camp in Xining.

Dong Ku stood in the wind, he watched the dark clouds roll in the sky, and suddenly his eyes went blank.

It's been four hours, the sky hasn't been clear, and the area covered by the strong wind is already hundreds of kilometers in a straight line, and the members of the Lhasa and Huya teams also have news that there is also a strong wind there, and the snow is blowing all over the sky.

The summary of this information, he didn't care about it at first, but when the wind didn't stop for four hours and reached level eight or nine, he suddenly remembered the reason for this.

The Northeast, namely Heilongjiang, and even Siberia, are affected by the Arctic cold snap, and there will be a windy season in winter, and not necessarily once, for a period of time. On the plateau, in addition to the irregular climate change, there is a windy season before the beginning of spring.

This is because of the warm air flow, which leads to the phenomenon of alternating between hot and cold. Although the plateau is not affected by the ocean, warm air currents are still present, so this leads to high winds on the plateau from time to time, and there is a fixed windy season in April and May.

How to forget this stubble!

Dong Ku was secretly annoyed. However, it was said that everything was over, and fortunately the most basic air raids were completed on the first day, and if the strong winds continued, the air raids could not be carried out, and even the attack on Tibet would have to be postponed.

"Herald!"

Dong Ku didn't think much about it, and shouted without looking back: "Send a telegram to Yu Lei, let him give up training, keep warm and keep out the cold, and wait for the wind to stop." ”

"Tang Ming, who is transporting supplies, sends electricity, asks him to prepare yaks, and after the wind becomes smaller, he advances into Yushu to deliver food and supplies to Yu Lei!"

"Yes!"

In the gale, No. 5 stood upright, turned around and ran to the headquarters.

Zuo Boyang looked at the changes in the sky and pondered and said loudly: "Captain, this gale can't stop for a day or two, we really have to be prepared for prevention, the army is stationed, food and heating materials are the most important, we must arrange it as soon as possible." ”

"yes!"

Dong Ku glanced at the debris in the sky that was swept up by the wind, waved his hand and ordered to return to the command headquarters while saying, "The little devil can live a few more days, and we can't attack for the time being." ”

With these orders given, the units returned to their cantonments, sheltering from the strong winds. The Japanese army would not be able to do anything, and they also avoided the strong winds, so that the imminent tensions could be relieved.

The gale lasted for more than five hours, slowly weakening in the afternoon and the sky cleared.

However, Dong Ku did not give the order for an air raid, but only asked Tang Ming to step up the delivery of supplies to the Yushu army to ensure the supply of the army there. He knew that the wind would stop, and it would not necessarily burn out of time and the wind would rise, it might be continuous, it might be intermittent, but no matter which one it was, it would not be suitable for air raids.

Besides, at two o'clock in the afternoon, the plane flew more than 200 kilometers in one hour, and it was dark when it arrived in Lhasa.

In the afternoon, the sky was clear and cloudless, yo, it wasn't the clutter piled up in the corner, which meant that it was still fighting the wind just now, which really made people think that the weather here was excellent.

Dong Ku ate fresh fish from Qinghai Lake and had no intention of moving again. He knew that a rash attack would cause the troops to be stranded on the road due to the snow rolled up by the strong wind, and that they could only wait for the attack after June. As for air raids, let's see if you will have sunny weather tomorrow, see if the weather forecast can have the possibility of air raids, and then decide whether there will be air raids or not.

The gale stopped, and Okamura Ninji, who was marching towards the wrong one, continued to advance there, and Seishiro Itagaki did not stop heading towards Yato. They didn't have much time and had to prepare in advance, at least the outpost had to approach the British lines, check the British defenses, and look for the timing and entry point for the attack.

In India, groups of recruits were gathered, untrained, and only marched at the back of the assembly, sitting in a queue with discipline training, guns, and not even bullets.

Churchill will not care about the life or death of these recruits, this is a colony, what does it matter to them whether they live or die, with these cannon fodder, their troops can reduce casualties and block the Japanese army.

In the busyness of all parties, the next day, it was still sunny, and according to the forecast of the meteorological department in Dong Ku's hand, the weather will not change today. As a result, several helicopter formations took off into the air at 9 a.m. and flew towards Lhasa.

In Lhasa, the Japanese army began to urgently build a defensive line yesterday afternoon, and all the anti-aircraft guns and anti-aircraft machine guns that had not been able to support it before were erected, and they were properly camouflaged before dark. At the same time, light machine guns were also scattered around the commanding heights and erected.

The first day's airstrikes did not do much harm to the Tibetans, which allowed the Tibetans to discover the key to this. Except for the houses occupied by the Japanese who were attacked, those iron eagles did not attack them, which shows that those iron eagles did not say to the serf owners that they would kill people when they saw them, and as long as they stayed away from the Japanese army, they would not be attacked and killed.

In view of this situation, the Tibetans were united by the Japanese army there, fearing that they would be horrifously killed by the Iron Eagle. The Japanese army did not force these Tibetans who were hiding from the plague to work, and it was not yet time, and they could not afford to worry about internal and external troubles. Angering these fierce natives will draw their energy against the advance army.

Therefore, except for the puppet army they recruited, they did not drive the Tibetans to work. Even if a puppet army escaped home, there was no senior search. Alone busy building a position, making the last dying struggle. (To be continued......)
