Besides, the materials needed to make gunpowder are stored in the territory except for sulfur.

As for sulfur, adventurers need to bring it out of the vast mountains.

So in this month's time, the star adventurers of the adventure Association have another task, which is to go to the vast mountains to find a kind of yellow stone with pungent smell.

At present, the number of adventurers' Association has increased to about 10000, and even several spirit controlling realm warriors have joined the association.

However, these adventurers usually don't take them with them in their territory. Instead, they travel around looking for materials suitable for their promotion.

As for other levels of martial arts are countless, it can be said that the adventurer association has become a giant.

If anyone attacks Yongfeng City, they will be attacked by them.

Soon, Zhao Fengnian got all the materials for making gunpowder, and what was left was a little bit of mixing to find out the most suitable proportion.

This process is undoubtedly painful for Zhao Fengnian and Shi Fu, Wang Fenglin and Li Tiezhu.

Because if they can't do it well, they will explode, although for powerful warriors.

It's just that ordinary explosions don't do any real damage, but it's also common to get burnt hair or get a bad look.

As a result, several people including Zhao Fengnian all shaved their heads. The appearance of several bald heads together to study things makes people smile.

However, although the process was hard and painful, when Zhao Fengnian saw that the first gunpowder was developed, he felt that everything was worth it.

This gunpowder can be used not only for war equipment, but also for the collection of black iron ore and stone materials in the territory, foundation construction and even entertainment for people's livelihood.

Just as Zhao Fengnian finished his work and was preparing for the next study, Tao an suddenly sent information saying that the enemy troops on the blue river had moved!

Half an hour ago, a group of cavalry came from the direction of blue river city. In the chariot behind the cavalry, LAN Tianyu himself was sitting.

But LAN Tianyu's son LAN Yanghe and military adviser Liu Yusheng are not among them.

After LAN Tianyu came to the position, he began to call his officers and soldiers into the camp and began to talk in secret

however, what LAN Tianyu and others did not notice was that on the camp tent and trees, there were several pigeon like birds staring at every move in the camp.

Now, because of the intelligence of the same kind to help transmit information, and reconnaissance intelligence, so that the enemy's every move can not escape the eyes of Yongfeng leading intelligence organizations.

Xiaozhi's first generation has been promoted to several levels because of taking a large number of spiritual cores. The appearance of Xiaozhi's first generation is different from that of ordinary carrier pigeons.

The body shape remains the same, but the fur color has turned into a solid color. There are several feathers growing on the head. It looks like a harmless ornamental pet bird.

But their strength, speed and intelligence have been greatly improved.

With the training of intelligence personnel, we can understand a lot of instructions and complete many tasks.

"Half an hour ago, lantianyu went to the garrison camp? And there was a meeting? "

Zhao Fengnian looked at the intelligence and frowned and thought deeply.

This information is very timely and important. Since LAN Tianyu has appeared, he must be ready to attack.

However, the enemy has only assembled 50000 troops, which is twice the number of Yongfeng soldiers. However, as long as people who are not stupid know that it is impossible for them to capture Yongfeng leader.

So Lan Tian Yu is stupid? incorrect! He has suffered a lot. He must have other plans.
