The arrival of the envoy of Yan State to Tang State was both unexpected and reasonable for the Chang'an court.

Today, in the East Asian continent, the Ming Tang Yan was the most powerful three forces, and they were all bound by each other, and the Ming Tang Yan, who was completely disabled in the civil war, and they were all bordering each other.

After the Ming army conquered the northwest region, the situation of the three kingdoms formed a delicate balance.

However, Richard's Liangzhou battle completely broke this balance. Not to mention the Tang court, even An Lushan did not expect that Richard could use only 20,000 troops and an invulnerable giant monster to defeat the army of more than 100,000 with a strong city!

Since the Ming army could rely on giant monsters to break the city once, it would naturally break the second and third time...

Moreover, after the Ming army quickly advanced south to capture Shanzhou and Huizhou, the situation in the Ming and Tang dynasties had reversed. To outsiders, it was because the Ming and Tang dynasties were strong!

Now that Yan State has endured the main force of the Green-skinned Orc army to the south, An Lushan cannot withdraw his troops to attack the northwest region under the control of Ming State, so he naturally does not want to watch Tang State collapse under the attack of Ming State.

Therefore, An Lushan had a plan to join Tang and fight against Ming.

The Chang'an court, who was worried about how to resist the Ming army, grandly received the envoys of Yan State. The two sides quickly reached an offensive and defense mutual assistance alliance. Tang State could withdraw all regular troops from the Yan State's border with peace of mind. At the same time, the troops deployed by Yan State on the Tang State's border were also drawn out to start a war against the Ming State!

The news of the alliance between the Tang and Yan countries soon came to Richard's ears. He was busy taking over Shanzhou and Huizhou. Richard, who was busy raiding his home, had to order the Liangzhou army to stop the attack.

The Northwest region has completed equalizing the land debt exemption, and it is also regarded as the source of the new army by Richard. Once the Yan army suddenly enters, the order and economic production that the Northwest region has finally recovered will be severely damaged immediately!

In order to stab the Ming Dynasty, An Lushan drew all more than 30,000 field troops from the Tang-Yan border and prepared to advance to the northwest region of Ming Dynasty.

At the same time, more than 30,000 regular troops from the Tang Kingdom gathered nearly 20,000 people to defend the south, and formed a 50,000 army to hurried towards Chang'an City.

In order to resist the attack of the Ming army, the Chang'an court not only transferred all the regular troops on the Tang and Yan border, but also transferred most of the regular troops from the southern defense to defend the independent Jiedu warlords, leaving only 10,000 people to stand out and scatter on the vast line of defense.

This behavior of the Tang State is very dangerous, because after years of war and annexation of each other, two major military groups have been formed. One is the Song State established by the Zhao family of the Southeast clan, and the other is the Jiedu alliance that still fought against the Tang State's court.

The Zhao family on the southeast coast used the method of joining the lunar and crossing the distant and attacking the near, and greedy and swallowing most of the independent Jiedushi, and the small half of the Jiedushi who was still loyal to the Tang Dynasty, thus forming a situation where one family was dominant.

The remaining Jiedu warlords in the south were not fools. After finding that their separate forces could no longer fight against the Zhao Song State, they immediately gathered under the banner of the Tang State, and did not mention independence. They united with each other into a military alliance to resist the Zhao Song State's invasion!

The reason why the Zhao family Song Kingdom stood out in the chaos in the south was because they took the lead in using black gunpowder in actual combat or used it on a large scale!

The four major war weapons of the sudden musket, thunder, thunderbolt cannon, and fierce turret cabinet made the governor of the Southern Tang Dynasty suffer great losses!

The storm is the most primitive firearm with black gunpowder as the driving force. Simply put, it is a hollow long tube filled with black gunpowder at the back and put a projectile in front. After igniting the black gunpowder, it can rely on the driving force generated by the violent combustion to shoot the projectile out.

Due to the poor airtightness, the range is naturally very pounding, and it is not comparable to the crossbow, but it has a huge advantage. Its armor-breaking ability is super strong, and it cannot even defend against heavy armor within ten meters!

This invention was specially designed by the Song army to deal with the heavy armored warrior commando under the command of various Jiedushi governors. The effect was very good. The Song army was also the first army to defeat the heavy armored warriors with ordinary soldiers!

The thunder of the sky is a primitive grenade filled with black gunpowder, which is a powerful weapon to defend the city. When defending the city, it can not only effectively attack the morale of the enemy, but also kill and injure the enemy's siege personnel in large quantities.

The people who were injured and killed by the thunder were very miserable. Many of the troops of the governors were defeated by the thunder!

The thunder cannon is a primitive artillery and is also the first artillery that appeared on the East Asian continent. Its performance is extremely poor, but because the enemy does not even have the most primitive artillery, it often performs strange results on the battlefield, especially in siege battles. Often, a few shots can scare the guard soldiers and their morale collapse!

The fierce oil tank is a primitive flamethrower filled with oil. It is generally used by the Song army in water battles. Almost all Song army warships are equipped with fierce oil tanks.

Because there are many water in the south, there are well-connected branches of rivers everywhere. Whoever controls the rivers can quickly mobilize the army and materials to most areas in the south, gaining considerable strategic advantage.

During the confrontation between river warships, the Song army's fierce oil cabinet used a large amount of flame spray to burn enemy warships. It often collapsed the enemy warship's will to resist without a fight, and achieved the first contactless victory of warships in the era of cold weapons!

Since the flames of the turbulent oil cabinet contain a large amount of oil, it is difficult to eliminate ordinary water sources after being sprayed onto wooden warships. Therefore, the Song army quickly controlled the control of the entire southern waters with the turbulent oil cabinet, and took advantage of the maneuverability of water transportation, frequently attacked more and sieged cities and land, and the effect was even greater than the previous three!

These four war weapons made the Song army unbeatable and gradually gained an absolute advantage in the south, forcing the undestroyed military commanders and warlords to continue to take the banner of the Tang Dynasty and build a group to protect themselves...

It was precisely because the Tang State saw this situation that it dared to draw a large number of regular troops on the southern defense line to defend against the Ming army's invasion. In the eyes of the Tang State, the military governors and warlords under the banner of the Tang Dynasty were natural barriers.

Originally, the Tang State also wanted to intervene in the war in the south to prevent the Zhao family from becoming popular. Unfortunately, the Ming army's invasion forced the Tang State to withdraw its help...

You know, without the support of the Tang State, the southern Jiedu warlords would have been wiped out by the Zhao State Song State!

At that time, a Song State that can confront the Chang'an court will appear along the southeast coast!

However, when the Ming army invaded the Central Plains, the Tang Kingdom drew back its energy to join forces with Yan to fight against the Ming Kingdom, allowing the Song Kingdom to see another opportunity.

When the war between the Central Plains, Northwest and Yanyun lands was about to begin, the southeast coastal areas became in chaos again!
