Yan Yun's sudden westward march this time to crusade against the former Western Xia territory where the Great Song Dynasty and Tufan's army was located has been questioned by many parties, including Yanyun's territory, there are also many doubts, Lu Junyi is just one of the typical representatives, in fact, there are more people who are worried about the prospects of this war.

If it weren't for the strong appeal and command of Wuda in Yanyun, I am afraid that this expedition would encounter greater pressure from all directions.

And in the end, why did Lu Junyi agree to Wuhan University's approach?

At this point, the mystery is finally revealed.

The Great Song and Tufan formed an alliance and once tried to get their hands on Yanyun Xijing Province together, and there is no doubt that an alliance was temporarily reached between the two countries, although this alliance was not strong, but it was an alliance after all.

Yanyun's army attacked, Tufan blocked Yanyun's army head-on, and Da Song wanted to encircle Yanyun from the side, this is the countermeasure that Tufan and Da Song had discussed before, and wiped out Yanyun in one fell swoop.

However, just when Yan Yun and Tufan fell into a white-hot battle, the biggest variable finally appeared.

The Great Song border army arrived as promised and launched a rapid offensive, but the target of their attack was not the Yanyun army, but Tufan!

That's right, Da Song attacked Tufan!

So the question is, Da Song Ming and Tufan formed a temporary alliance, why did they suddenly turn against the water and join forces with Yan Yun to attack Tufan?

The reason was that before Wu Da returned to Yanyun from the Wa Kingdom, he was on the giant ship of Yanyun Sailor and handed over the letter to Dongguo Taixun.

That letter was written by Wu Da to Song Huizong.

The content of the letter is very short, and its core is also very straightforward, Wuda gave Song Huizong a huge temptation that absolutely cannot refuse, a great temptation that no generation of kings in the world can refuse since ancient times, that is, to expand the territory.

Expanding the territory is the dream of all dynasties, all kings, all capable officials, and even all people with lofty ideals.

After all, everyone wants to go down in history, and few people want to be famous for 10,000 years.

And the great achievement of wanting to leave a name in history and expand the territory is undoubtedly the strongest evidence.

Especially for emperors, this is the most important and arduous task in their lives.

Wuda said very clearly to Song Huizong, very simple and rude, if Song Huizong intends to expand the territory on a large scale, then as a Han Chinese, Wuda will definitely not be stingy to help the Great Song Dynasty.

And the expansion of the territory that Wuhan University refers to is the entire northwest!

The northwest region is incomparably huge, with three tribes of Tufan, Uighur and Black Khan, or three major kingdoms, a small Xijing Province, which can never be compared with the northwest.

Besides, Song Huizong's heart is clear, and everyone in the world knows that as long as Wuda is in Yanyun one day, Yanyun is definitely an extremely difficult hard bone, even if Da Song and Tufan join forces to fight Yan Yun to the death, even if Yan Yun really loses in the end, then Yan Yun will definitely bite back fiercely, so that Da Song and Tufan will pay enough price.

What's more, no one dares to guarantee that the martial arts officials, who have always been known for turning decay into magic, and have directly wiped out the entire territory of the Wa Kingdom in the middle of the hand, and their means are becoming more and more unpredictable.

In addition, the relationship between Yan Yun and the Liao State is now in a state of cold lips and teeth, and the Liao State is dead, Yan Yun may not be affected too much, but if Yan Yun is gone, then the impact on the Liao State is absolutely unimaginable.

Once there is no Yan Yun as a barrier, the Liao State will need to personally face the direct pressure from the Great Song Dynasty and the Northwest Three Kingdoms, as well as Goryeo, won't the Liao State also follow in the footsteps of Yan Yun and go to destruction?

Therefore, no matter who wants to destroy Yan Yun under the current pattern, the Liao State will definitely send troops to help Yan Yun at all costs.

In addition, don't forget that Dali, a small country in the south of the Great Song Dynasty, is also inextricably linked with Yanyun, Yanyun is dead, and the next country to die must be Dali, and Dali will perish earlier than Liao, so Dali will not sit idly by and watch Yanyun be destroyed.

In short, Yan Yun's own strength is strong enough, and there are two foreign aids, one in the south and one in the north, and the Great Song Dynasty wants to get involved in Yan Yun, but the price paid is too high, and the pay is seriously disproportionate to the gain, and it is very likely that the bamboo basket will be empty.

And if according to what Wu Da said in the letter, as long as Song Huizong and Yan Yun join forces, then Yan Yun will help the Great Song Dynasty to crusade against the northwest.

Putting aside such a major event as the crusade against the Northwest for the time being, the bait thrown by Wuda to Song Huizong was half of the territory of the former Western Xia occupied by Tufan.

At the beginning, the Great Song Dynasty took the initiative to send troops to crusade against the Western Xia, but Tufan took the opportunity to send troops to pick up the cheap, and finally it became that the Western Xia was destroyed by the Great Song Dynasty and Tufan together, and the original Western Xia territory was finally divided into two by the Great Song Dynasty and Tufan, which has always been a thorn in the heart of the Great Song Dynasty, and if it is not resolved, the heart will always feel uncomfortable.

Therefore, when Wuda said in the letter that Yan Yun would join forces with the Great Song Dynasty to take the lead in destroying the 50,000 Tufan army in the territory of Western Xia, and surrender the entire territory of Western Xia to the Great Song Dynasty, and only needed the Great Song Dynasty to compensate for enough materials and money, Song Huizong agreed to join forces with Yan Yun without hesitation.

While Wuda was preparing in Ningbian Prefecture, Song Huizong had also issued a secret order to the Great Song Border Army, so that they could temporarily perfunctory.

At the same time, the Song Hui Sect sent henchmen to secretly enter Ningbian Prefecture, and in accordance with the instructions of Wuda, they reached the plan of "repairing the plank road in the open and Chencang in the dark", and spitting out an army of 50,000 in the shadow.

On that day, Lu Junyi vigorously refuted Wu Da and waved his troops westward, and Wu Da was helpless, so he informed Lu Junyi of this matter in advance, so Lu Junyi was so shocked at that time.

This is also the biggest reason why Lu Junyi agreed to Wuda's crusade against the territory of Western Xia.

Wuda and Song Huizong have a blood feud, and even Lu Junyi was shocked that Wuda could actually take revenge on Tufan, and forbearance to the plan to temporarily join forces with Song Huizong.

Tufan is very wronged, very wronged, although they are also a fighting nation, with strong combat effectiveness, but they do not have the supreme weapon of earth-shaking thunder and fierce fire oil in their hands, besides, their number is too small compared to the current Great Song and Yanyun coalition forces.

After being bombarded by Yan Yun and ravaged by Yan Yun's cavalry, the Tufan 50,000 army, which suffered heavy losses, was tightly surrounded by the 80,000 border army of the Great Song Dynasty and the 30,000 army of Yan Yun.

And then there was the merciless slaughter!

Tufan, one of the two great kingdoms that once tried to get his hands on Yan Yun, paid the price of blood within half a month!
