It is said that the eunuch surnamed Cai, who was in a foreign country, was killed by the aliens, and his head was hung above the gate of Chang'an for three days.

"Well deserved!" Li Xiongba chirped.

No matter ancient or modern, to start a war, you need to be famous, otherwise the people will live well, and if you suddenly go to war, it will be easy to lose the support of the people. This is also the reason why Emperor Shenwu has been standing still after signing an alliance with the northern court.

However, this time the situation is completely different.

The iron hooves of the alien race stepped into the Central Plains, and the people of the Tang Dynasty were in danger.

Emperor Shenwu personally wrote an impassioned essay against thieves, calling on the people of the world to "drive out the Tartars and restore China." ”

She drove the expedition in person, fought fiercely, and pointed at Chang'an.

The teacher of justice, the followers of nature.

After crossing the Yangtze River to the north, the Central Plains, which was in turmoil, had many people with lofty ideals who came to join. In many places, the separatist forces opened the city gates one after another, and merged into the king's division to jointly crusade against foreign races.

Due to the rapid action, the Chang'an court was still in turmoil, Li Xiongba followed Emperor Shenwu, all the way north, almost unobstructed, drove straight in, and arrived at Tongguan in a few days.

Tongguan is the last barrier of Chang'an, the foreign court is heavily guarded here, they have sufficient food supply, and there is a favorable location to defend, the king division marched thousands of miles in just a few dozen days, has been very tired, attacked for several days, it is impossible to attack for a long time.

"I didn't expect this group of aliens to be so powerful." Under the military tent, after everyone finished their deliberations and retreated, Li Xiongba couldn't help but complain to Emperor Shenwu.

Yes, within the scope of his cognition, the ancient marches and wars were all fought by people, and there was no supernatural force involved.

And on their side, there are not only strong soldiers and horses, powerful siege weapons, but also demons and Daomen to join.

"Why can't you win?" He wondered.

"Little butterflies, can't they change in, become aliens, fly up to the city gate and blend in, catch the alien boss, and put them directly into a bag and bring them back." He thought secretly. "No matter how powerful the alien boss is, he is still a person, how can he compare with a demon."

He frowned and sighed.

Emperor Shenwu on the side seemed to see what he was thinking, and explained:

"Dao law and demon power, although they are powerful, they also have a way to crack it."

"There are also a lot of capable people over there, and the people of the Junshan Yin Yang Sect fought with them thirty miles away yesterday, and they lost both. You just don't know. ”

What?

And such things?

Li Xiongba's eyes widened.

"At first, they intended to attract floods, to flood the Seventh Army, and later they attracted heavenly fires to burn our grain and grass."

！！！

"And then?" Li Xiongba worried.

"Naturally, it was cracked." Emperor Shenwu Dao. "However, there are several seniors who are also seriously injured and can't fight anymore."

"As for Little Butterfly, he can't even enter the city gate."

"Why?" Li Xiongba said strangely.

"Master Yuanzhi's demon subduing enchantment, I don't know who arranged it on this Tongguan, the demon within a thousand years, as long as it gets close, it will lose all its demon power."

Ah。。。。。。h

No wonder the little butterfly has been following the princess obediently lately and has not gone anywhere.

It turns out that the war with demon power and mana is even more troublesome.

"Then at present, what should we do to capture Tongguan?" Li Xiongba asked.

"It's really tricky right now." Emperor Shenwu frowned. "Their rear supply is sufficient, and we have already consumed a lot of energy and food and grass, so I am afraid that it will be difficult to compete for the time being."

"That is to say...... Are we going to retreat? ”
