He immediately opened the design drawing of the Thunder War Drum.

【Rare Thunder War Drums: Metal Runes (0/1), Gold Nuggets (0/2), Leather (0/1), Thunder Beast Skeleton (0/2)】

[A powerful thunder war drum, after the drum sounds, the strength or momentum of your army will double, and the enemy's army will double.]

…

There is no shortage of materials.

Su Yuan smiled and clicked directly to create.

brush!

A flash of light appeared before his eyes.

The entire war drum is two meters in radius, with a radius of one meter alone. The base below is supported by gold nuggets, and the pattern of thunder beasts is carved on it, which looks hideous and terrifying.

"Dong!"

Su Yuan pulled out the drumstick and beat it hard.

A surging force instantly spread out from the drum's face, vast and mighty, as if it could affect a person's mind, causing his heart to be beating directly.

In an instant, his hair stood tall and his blood was boiling, and he felt like he was rushing on the battlefield.

"Sure enough, there are some tricks!"

Su Yuan was so proud.

Dong! Dong! Dong! Dong!

He beat the drums a few times again, and the sound of the drums became louder and his mind surged, and his true energy was also speeding up.

After he knocked seven or eight times in a row, the speed of the true qi in his body was more than twice as fast.

Situ Hao and the Red Dragon all rushed out of the house, looking surprised.

"Master, what is this?"

Situ Hao said in shock.

"Even you were affected?"

Su Yuan turned to look at them, stopped beating the drums and began to introduce them to the Thunder War Drum.

After hearing this, the two of them were stunned.

"Can this thing enhance your strength? Weak the opponent's strength?"

The red dragon said in a lost voice.

"Yes, how about it? You guys just now have some experiences?"

Su Yuan smiled.

"Yes, we were copying secret books in the room just now, and suddenly we felt that our true energy was not under control, and the speed of operation increased more than doubled!"

Situ Hao said.

"That's right."

Su Yuan smiled.

He asked the Skeleton Lord and the Terrifying Lord to come over and lifted the thunder war drum directly to the top of the city.

The higher the thing, the better it should be, and it will be useful at any time.

Next, Su Yuan smiled and walked towards the [Enhanced Tower] next to him, and directly entered the first floor of the [Enhanced Tower].

The entire enhancement tower is divided into seven layers, and the more you strengthen the items, the stronger the items are.

I saw a sarcophagus-like thing appeared in the middle of the room on the first floor, without a coffin lid, and was quietly placed there.

This is the core of [Enhanced Tower]!

Anything can be strengthened instantly as long as it is placed in a sarcophagus.

Su Yuan directly took a hard bow and two arrows and placed them gently inside.

brush!

A white light flashed, and the hard bow was strengthened on the spot.

Su Yuan grabbed the hard bow again, and saw that the weight of the original hard bow increased by more than three or four times. The black light on the bow tire was flashing, covered with mysterious patterns, which looked simple and heavy, and the bow strings became thick and large. When they pulled it hard, they made a squeaking sound.

[The Hunter's Bow: A high-quality treasure bow improved on the basis of the original hard bow. The power shot out can easily penetrate steel 150 meters away, and has a certain armor-breaking effect.]

【Extremely useful treasure bow, you are very lucky.】

…

Su Yuan's eyes glowed.

Hunter's Bow?

Can you break the armor?

Su Yuan took out the two reinforced arrows again, and saw that the two arrows became completely different. They used to be wooden arrow shafts, but only the front end was made of iron.

But now after strengthening, the entire arrow shaft seems to have become made of metal, and the front end part has become a spiral shape.

Su Yuan took the bow and arrow and walked out of the reinforcement tower, created a shield, and let the red dragon stand 150 meters away, and then tried to shoot an arrow himself.

Whoosh!

A gust of howling wind sounded, and the arrow rushed out a hundred meters in an instant. With a thunderous sound, the entire metal shield shot through the spot and passed by the red dragon.

The red dragon's face changed, "What a strong treasure bow!"

Su Yuan looked satisfied.

It has the effect of breaking armor!

He had thought about using the [Armor Breaking Bow] to arm all these skeleton soldiers, but the [Armor Breaking Bow] was extremely expensive and needed a metal rune to make it.

But now with the [Hunter's Bow], the [Armor Bow] can be saved.

Although [The Hunter's Bow] is not as good as the real [The Armor Bow] in terms of armor-breaking ability, it is also much stronger than the previous hard bow.

Su Yuan immediately called all the skeleton soldiers, and Xiong Da, Xiong Er, Luo San and others also called them to hand over all the weapons and pile them in the yard.

Then Su Yuan asked several skeleton soldiers to carry these weapons into the enhancement tower, throw them all into the sarcophagus, and strengthen them.

Not only bows and arrows, but also spears, shields, and leather armor are all strengthened once.

The newly enhanced weapons and equipment were quickly carried out again.

Su Yuan immediately asked these skeleton soldiers to replace them with new leather armor and weapons and equipment again.

Even with Xiong Da, Xiong Er also looked happy and put on new leather armor.

The enhanced leather armor color has become a dark black color, with a thickness of more than several times, but the weight has not changed much, and it is extremely warm and comfortable to wear on the body.

"Lord, you are so conscientious."

The bear laughed.

Su Yuan smiled: "Xiong Da, Xiong Er, from now on, you should stop maintaining public order and still guard your city walls. In addition, clear the snow and garbage in the city according to time!"

"Yes, Lord Lord!"

Xiong Da, Xiong Er left here with a smile.

As for those skeleton soldiers, Su Yuan left 15 as servants, and the other 20 were ready to hand them over to Zheng Feng later. As for the others, he sent them out and continued to defend the city.

[Evolution Factory] It should be built tomorrow. Once all the medicinal materials are mature, his skeleton soldiers will grow rapidly in a geometric multiple.

Su Yuan was confident for a moment.

"By the way, there are flash bomb fruits."

He immediately took out the 15 flash bomb fruits and handed them over to the skeleton soldiers, and asked them to plant them in the yard. He also gave them several bottles of primary evolution liquid to pour them on the fruits.

After all the instructions, Su Yuan took a breath and prepared to start another major event.

…

[Totem Pole: Divine Power Gem (0/1), Special Soul (0/2), Gold Nuggets (0/20), Metal Rune (0/2), Wood Rune (0/2), Water Rune (0/2), Fire Rune (0/2), Earth Rune (0/2).]

[The totem pole is the foundation of the dark world, and can evolve by absorbing more advanced souls.]

…

Su Yuan frowned directly.

Two runes with the five elements attributes are required.

Unfortunately, he had just completed the upgrade of the room special effects, and there was no shortage of other runes, except for one rune.

Su Yuan checked the remaining number of runes.

…

Normal Runes: 61
