While commanding the pet attack, Zhang Yang ran out of the cave and came outside. The ordinary bloody blade could kill most of his blood with one sword energy. If this elite sword energy with stronger abilities was caught, it would be possible to kill Zhang Yang directly, so Zhang Yang would not have time to see what the battle situation was.

After waiting for a long time, Zhang Yang thought that he could go in at this time, so he poked his head out little by little, as if he was afraid of being discovered, and slowly looked into the cave.

Monsters like Bloody Blade belong to the metal system. Strictly speaking, they are not creatures, so they cannot make screams, so they cannot judge the situation of the battle through the sound.

Zhang Yang knew very well that he was gambling with his life, betting on the attack direction of the Bloody Blade at this time. If he was lucky and was in the 240-degree attack corner of the Bloody Blade, then he would win the bet, otherwise he could directly kill himself in seconds with a sword.

Zhang Yang must go in, otherwise once a crossbow tower is destroyed and he will not go in to replenish it, the crossbow tower will slowly be dismantled.

Slowly he stuck his head into the cave. Sure enough, Zhang Yang saw a person-high bloody blade elite attacking a crossbow tower with a knife. At this moment, the elite seemed to have accumulated energy. Then, while his body was slightly shiny, he threw it out with a knife. A huge sword energy generated and spread out. In an instant, it passed through all the crossbow towers, and countless numbers of -1 floated up.

Zhang Yang could see clearly that this 240-degree sword energy occupied almost the vast majority of the space, and only a small area behind the elite was not affected. Zhang Yang was in this direction, so he was very lucky.

The attack power of the sword energy is very high, but there is no way to deal with fortifications that only force a little blood to be lost. At this time, Zhang Yang is level 45, attack power 151-284, the level of the crossbow tower is level 90, attack power 135-255, and there are 10 crossbow towers in total. One round of attack can destroy nearly 1,000 blood. This is equivalent to one percent of the blood loss for the Blood Blade Elite with only 100,000 blood. With blood recovery, Zhang Yang is estimated to need 150 rounds of attack to win this elite.

Every time the elite monster attacks more than ten times, it will emit a sword energy, causing all the crossbow towers to lose blood. Zhang Yang observed for a while and discovered this rule. So during the period when the elite monster attacks, he stepped forward to repair the fortifications. When he emits the sword energy, he hides. He can use the bloody blade elite to death.

Sure enough, it was similar to Zhang Yang's calculations. After 150 rounds of attacks, Zhang Yang's 10 crossbow towers were even destroyed, and it was too late to repair them. The Bloody Blade Elite finally made a clang, falling to the ground like scrap iron. At the same time, a pleasant music sounded, and several slightly shiny items appeared on the ground.

Zhang Yang's eyes lit up. At this time, he had been hiding at the entrance of the cave and quickly came over to pick up the items. The Bloody Blade Lord, who had just died, did not disappear like normal, but lay on the ground, but the blade was incomplete and only a small part was left, but it was this small part of the blade that made Zhang Yang laugh.

"Bloody Blade: Must Items for Upgrading to Level 5 Tribes".

With this thing, Zhang Yang can upgrade his tribe to level 5 at any time. If it weren't for it, Zhang Yang wouldn't have come to this place to level up. This place is very unfriendly to the engineering profession and is not a product of engineering.

After putting away the bloody blade, Zhang Yang took a look at the other spoils, a total of 7 pieces. It can be said that this is a little less, but when a drawing was discovered by Zhang Yang, Zhang Yang laughed again.

"Stone Age tribe architectural drawings: era ruins, building materials: 20,000 hard stones, 20,000 Nanshan woods, 1,000 ruins, and tribe level 5."

Zhang Yang had to laugh. It can be said that starting from the 5th level of the tribe, it was prepared for the evolution of the times. Among these preparations, there is one of the most important prerequisites, which is to fight the boss of the times, and the boss of the times is refreshed in the ruins of the times.

Now that this drawing is available, Zhang Yang’s preparations have been completed halfway.

The construction materials for the era ruins actually require a lot of money, 1,000 pieces, and according to the recent price, it is 1,000 gems. This is first of all, a lot of money, and 20,000 hard stones and Nanshan wood. Not every tribe can take out this money or is willing to take it out.

But Zhang Yang still has to take it because he must be the first to evolve the tribe so that he can return what a tribe in the United States did in the previous life and remain unchanged.

Except for the drawings and bloody blades, the remaining things that this elite monster dropped were gems and equipment. Zhang Yang put away all the things and took them out to the city scroll to use them directly. After a ray of light, Zhang Yang disappeared in place.

When he appeared again, Zhang Yang had already arrived at the main tribe.

First, he resurrected the pet from the pet NPC and stored the unnecessary things. Zhang Yang directly called Xiao Mining to communicate and asked him to send the needed materials back. Then Zhang Yang called out the tribe panel and started the upgrade.

"A tribe upgraded to level 5 requires 5 drawings of tribe upgrade, 2,000 hard stones, 2,000 Nanmu, 1,000 flawless stones, 1,000 Maple Nanmu, and a bloody blade. Are you sure?"

Zhang Yang had prepared these materials long ago and had been in the warehouse, so he directly clicked to confirm.

A ray of light came out across the tribe, and a pleasant music sounded, followed by the chiefs NPPs who had not shown their face for a long time, dancing an unknown original dance again.

Some players who stayed in the tribe also discovered an abnormality at this time. Some players with old qualifications have experienced such a thing, so they ran towards the bonfire in front of the chief's door and did not forget to notify their friends.

However, some new rookies who joined did not know what was happening at this time. They just saw someone running, and the tribe lit up weirdly, so they instinctively ran away, and did not forget to kindly remind the players passing by, "Run quickly, the tribe is about to explode..."

"Fry your sister..." He just returned to the small mine of the tribe, and looked dark when he heard this. These rookies were really good.

Not long after, the Chief NPC finished dancing, and each NPC began to re-divider the boundary lines, sharpened the stones and wood, placed them in the peripheral area, showing the tribe's range.

The gate of the tribe became wider at this time, and the two undead eyes formed by the top of the gate turned even more. A huge blade also appeared above the gate of the tribe, slightly suspended. Whenever a player enters the tribe, the blade will aim the tip of the knife at the player, as if it will be cut at any time.

This is the automatic defense system of the level 5 tribe: "Bloody Blade". Once a non-tribal player with the red name enters, the blade will automatically attack, blocking the danger directly from the tribe. However, during the war, the system will lose its effect.

At this time, the tribe naturally expanded again, and even included several small tribes around it. Fortunately, these tribes are downstream tribes of Friendship Horn, so they were automatically identified by the system as being annexed by the main tribe of Friendship Horn, and the original players were automatically incorporated into the main tribe.

This annexation mechanism makes it possible that once a tribe is upgraded, the territory will likely include another tribe. If these two tribes are not the same tribe or are not in sister relationships, a war will be forced. The tribe upgrade will not continue until one fails or surrenders. This is also the reason why Zhang Yang has been cleaning up the surrounding tribes. Even if he does not clear it, he will inevitably automatically start the war when the tribe is upgraded.
