The magic cannon can be said to be one of the greatest weapons of the goblin tribe. The higher goblin tribes are never liked by all races, but they can defeat many powerful intelligent races. The dragon tribes and the elves are unwilling to provoke them. They have gained their current status on the continent. At least half of the credits of this cannon. The magic cannon uses mixed elements as attack energy. Its power is very terrible and has the ability to kill the dragon. However, the magic cannon itself is not too expensive. The consumption caused during use is indeed unbearable by ordinary forces.

A low-level goblin magic cannon itself is not of high value, at most more than a thousand superior soul gems, but it requires lower-level spirit gems as energy. Two cannons can consume a lower-level spirit gem, which is equal to ten superior gems. The total energy consumption of firing one hundred cannons is equal to the value of the magic cannon itself, which is somewhat incredible.

Wentiancheng has the strong economic strength to catch up with Fengyun City. After experiencing the battle with the sea clan, he suddenly fell into a very tight capital. The two magic cannons have made considerable contributions. Fortunately, Wentiancheng has many economic sources and abundant resources. Therefore, the negative impact has not damaged the foundation and can be recovered in less than a few days.

A middle-level goblin magic cannon is worth about 10,000 high-level gems. The most unacceptable thing is that it is no longer the lower-level soul gems, but the precious intermediate spirit gems. An intermediate spirit gem is equal to ten lower-level spirit gems.

The two attacks of the intermediate magic cannon can consume one hundred superior soul gems. If a lasting war breaks out, even a few hundred cannons will be pulled down on the battlefield. The most important point is that the energy consumed by the intermediate magic cannon must be intermediate spirit gems, and cannot be filled with lower spirit gems or soul gems of equal energy. The spirit gems of each city are important reserve resources. The energy contained in a lower spirit gem is no different from ten superior soul gems. You can get it to the black market to trade and sell twelve upper soul gems, the higher the level, the higher the value. The intermediate spirit gems are extremely precious than the lower spirit gems.

Xiao Yu couldn't help but feel a little lucky. He was fortunate to learn an ancient alchemy in the truth world of the ancient tree of the elves' knowledge. It is a method of refining soul gems. This alchemy can extract the energy from the low-level soul gems, solidify and synthesize it again, and finally refine it into a high-level soul gem, but there will be energy consumption in the middle. Eleven upper-level soul gems can be refined into a lower-level soul gem.

Although there are not many spirit gems in each city, there are still many reserves, which is enough to consume at the current stage. However, when the mainland is in full swing, the price of spirit gems will rise greatly, and the value of this alchemy will be highlighted.

Xiaobai couldn't help but feel dizzy, and his pink and tender little face turned a little white, "Two...two thousand superior soul gems? So many"

Xiao Yu just frowned slightly and said readily: "Okay, I want this."

The price is higher, but it is acceptable. Wentiancheng already has four low-level goblin magic cannons. If there is an extremely powerful middle-level goblin magic cannon, it can ensure that it is foolproof.

Xiaobai's big eyes were full of admiration, thinking: "There is no blinking the eyes of the top 20,000 gems, the master is really courageous."

Xiao Yu waved to Xiaobai: "Let's go and see other products and see what the difference is between intermediate stores and low-end stores."

"Okay, master"

There are dozens of products in intermediate goblin stores than in low-end stores. Xiaobai glanced at the neatly arranged equipment and materials, and suddenly shouted, "...Cell rejection inhibitors strengthen life stability gas strengthen biochemical nutrition warehouses... Ah, they are the most lacking equipment in the institute now or the old owner, let's buy a few of them."

"No need to worry, I bought it all"

Xiao Yu was paying a huge sum of more than 10,000 yuan of soul gems of superiors. As long as Xiao Bai saw the materials or equipment, he bought all the materials or equipment that he had not lost. Xiao Bai jumped happily and hugged Xiao Yu's arm excitedly. Xiao Bai was a little nervous when he made this move. He glanced at Xiao Yu and found that the master was not in a hurry to push him away as if he was encouraged. He immediately "gone more" and rubbed Xiao Yu's arm desperately with a round snowball through a thin layer of fabric.

"You are the most generous and good master in the world. Xiaobai is so happy that he can be by your side. Don't worry, the master. With the addition of these materials and equipment, the institute will have a leap forward and improve. Xiaobai will not disappoint you."

Xiaobai flatters are very tacky, but it gives people a very useful feeling

Xiao Yu then checked other products one by one. The products in the middle-level goblin store are mainly third-level items, and even contain a small number of fourth-level precious materials and special items. There is an area, which shows a large number of advanced goblin war weapons, mainly three types.

The weapon "Gomin Small Helicopter C-class" has been seen at auction. It has strong maneuverability and is quite fierce in firepower. It is suitable for reconnaissance and assault. The force field shield can greatly enhance the helicopter's defense ability, resist magic and physical attacks, protect it from being destroyed, and allow it to fly safely in various environments.

"Gomin missile vehicle C-class" is about the same size as a medium-sized truck. It can be equipped with a large B-class goblin missile on the body to accurately strike targets more than ten kilometers away, with a long range and huge destructive power. It can reach level 4 suitable for attacking fixed and difficult-to-destruct targets, such as cities, buildings, etc. The disadvantage is that it can only install and launch a long-range missile at a time, and cannot continuously attack targets, and does not have combat effectiveness at mid- and close distances.

"Gopter Ocean Battleship C-class", this is a dual-purpose underwater weapon. It can sink into the bottom of the water like a submarine, and at the same time it can shuttle quickly on the water like a warship. It has a force field shield and can launch C-class small goblin missiles and torpedoes. Its destructive power and firepower are quite good.

The three war weapons are used for air and air respectively. The price is 1,500 superior gems. Missiles and bullets are consumables and are not included. Additional purchases are required.

"The helicopter that Cao Lao Fox bought directly from high and low-level players is only 1,500 at most. I didn't expect that it would be fine if he sold it at a high price of 4,500 at the auction. After the upgrade of the goblin store, he would never want to make money from Wentiancheng in a short time."

"Master, come and see, there is a power field shield ring here."

Xiao Yu walked over and saw Xiaobai pointing at a dozen C-level force field shield rings, and his face showed excitement. Without exception, it was a full ring with a full energy point of 1,000 points, and only 550 superior soul gems were sold.

Xiao Yu was very surprised and unexpected. The force field shield ring was affordable, but it was very useful. At this price, Xiao Yu could equip all senior members of Wentian City with one, which greatly improved their survivability.

More than 10,000 yuan of soul gems from Princess Shuilan was spent in just two hours, and I also took a few thousand extras. However, I gained a lot of money not only bought a lot of materials and equipment for the institute, but also brought Wentiancheng two helicopters, missile vehicles, combat squadrons, and more than a dozen force-field shield rings.

The intermediate goblin store has a very rich product, with elemental cannons, elemental guns, goblin missiles and bombs of various attributes, all of which are very practical items. Unfortunately, there are not enough soul gems, so it is not possible to buy them for the time being.

After Xiao Yu left the shop, helicopters and missile vehicles were left for the weak fox men to study and use, while combat boats were placed into the lake to enhance Wentian City's water combat power.

At this time, a consul of Wentian City suddenly found Xiao Yu and hurriedly said to him: "City Lord, our intelligence personnel have brought back an important news."

"What information?"

"A magic disaster broke out in a few places on the mainland, and a human city has been captured. The lords of each city attach great importance to this. Now everyone believes your prophecy, and each city is nervous and alert."

"Damn disaster, has it appeared?" Xiao Yu touched his chin, "How many days were it faster than expected, how many outbreaks are there, how many dark races and abyss races are there?"

"The number cannot be estimated, the area of ​​the magic disaster is not very large. There are a large number of third-level or even monsters in that area, which has attracted the attention of the city lords of various cities to pour into the nearby cities and start hunting monsters in the disaster area." He said as he opened the map, pointed to one direction, and drew a small circle, "Please look at the city lord, it's probably here."

Xiao Yu looked at it carefully. The area eroded by the magic disaster is about hundreds of thousands of square kilometers, and there are six or seven cities nearby. The strongest one is Canglong City, a member of the Wentian Alliance, and one of the five famous cities in the mainland.

"Okay, I get it, you go down"

"Yes, the city lord"

Xiao Yu's strength has stopped moving forward for some days. On the one hand, due to personal factors and some trivial matters in the city, and on the other hand, it is limited to the environment. It is difficult to find monsters of the same level or smart race nearby. Many people on the continent have gradually caught up. Han Kexin and Zhao Changping have advanced one after another, and their realm is very close to him.

Xiao Yu was already planning to go to Canglong City to challenge the "Phantom Demon Palace" and receive monthly "benefits". A magic disaster broke out there. By the way, he went there and left his strength. His strength was only a line away from the early stage of the fourth level. As long as he hunted a few fourth-level abyss monsters, the items dropped by the fourth-level monsters that could be upgraded were extremely valuable. This trip can also be regarded as making some extra money to make up for the situation of insufficient capital in the city.

Without further ado, Xiao Yu set out that day, leaving the butcher in Wentian City, sending Wang and Jinshi to the outpost in front of the dark crack to guard the situation in case of accidents
