“…”

After the first-level armed fortress base was upgraded, all the main combat robots replaced their guns and were promoted to one level. At the same time, a large number of powerful combat weapons and special forces appeared.

Those special forces are special forces made of Vidania's body materials after Yang Feng killed the ancient black dragon Vidania, No. 3796.

A burning look flashed in Yang Feng's eyes and immediately ordered: "Comprehensive evaluation of combat power level 10 means that this is a mechanical black dragon with combat power comparable to that of the great warlock level. And it is a mechanical black dragon that can continue to evolve. It's so great! Create a mechanical black dragon for me immediately."

"Yes! Master!"

If a mechanical black dragon with combat power comparable to a great warlock appears in the City of Steel, the City of Steel can immediately become a powerful existence with combat power second only to the Antalya Warlock Academy and other six major forces.

After the level 1 mobile fortress base was established and the large matter and energy converter was established, the conversion of the dimensional crystal was much simpler and easier than before. With the energy that Yang Feng currently has, 100 units of dimensional crystal can be converted in one day. Yang Feng no longer needs to search for dimensional crystals everywhere.

No. 3796 asked: "Currently, steel reserves are insufficient. Will the old model of main combat robot be melted back to the furnace to create higher-level main combat robots?"

At present, the power of the entire Iron City has become a huge arsenal. Every day, a large number of various ores will be mined and then made into main battle robots.

However, the sphere of influence of the City of Steel is limited after all, and various metal veins are also very limited. Under the terrifying mining efficiency of Yang Feng's huge mechanical legion, the veins began to dry up. Yang Feng's mechanical legion was also subject to resources and could not continue to expand wildly.

As for the tax revenue of the Iron City, Yang Feng concentrated it up, and partly divided it to buy a large amount of ore, while the other part was to pay for his own salary.

Yang Feng pondered for a while and said, "Then let the old model of main combat robot be restored to the furnace when there is insufficient ore."

"yes!"

After Yang Feng issued a series of manufacturing orders, he left the interior of the mobile armed fortress.

"It's a pity that my sphere of influence is too small and my development is limited. It seems that I have to open up a source of wealth, otherwise a mere steel city would not be able to meet my cultivation needs at all."

"By the way, you can sell alchemy potions such as the Phantom Blue Demon, Mermaid Tears, and Dragon Blood Potion. Each bottle can be sold at a sky-high price." Yang Feng thought while walking, and suddenly his eyes lit up, and a smile appeared.

The three potions of Fantasy Blue Demon, Mermaid Tears, and Dragon Blood Potion are all top alchemy potions. Due to materials and craftsmanship, many alchemists have very low success rates in refining these three potions. Yang Feng has a large energy and matter converter, so he can easily synthesize these three alchemy potions directly. If he is taken out for sale, he will definitely be sold at a sky-high price.

Yang Feng suddenly asked: "Can the high-frequency oscillation knife break through Vidania's dragon scales?"

When fighting with Vidania, the level 7 mechanical warriors under Yang Feng could hardly break through the dragon scales on Vidania's body. If Vidania hadn't had a large number of old injuries, he would not have killed this terrifying ancient black dragon.

"The high-frequency oscillation knife can already break the dragon scales on Vidania's body. However, according to current data analysis, if Vidania is in its heyday, it is almost impossible for the second generation of main warriors to defeat it unless it can limit its movement."

Yang Feng pondered for a while and ordered: "After building the mechanical black dragon, mobilize half of the resources to synthesize three alchemy potions, namely the Phantom Blue Demon, Mermaid Tears, and Dragon Blood Potion."

"Yes! Master!"

"Then it's time to improve your actual combat capabilities!" Yang Feng took a deep breath and walked into the oval virtual reality combat cabin placed aside.

"Please choose terrain, grassland, desert, plain, city, ocean, hills, forests, swamps... or mixed terrain."

"Select your opponent as the first-level warlock Boni, and the battle location is the plain."

"Understand, initialization begins!"

"Initialization is completed! I wish you a prosperous martial arts fortune!"

Yang Feng's eyes lit up and found that he had appeared in a plain with a radius of hundreds of kilometers. A hundred meters away from him stood an old man, Boni, the owner of the Black House.

"The battle begins!"

As soon as a voice sounded, Boni, opposite him silently chanted the spell. With a wave of his hand, the first level of magic was weak and weak, and he directly enveloped Yang Feng.

"Black Dragon Scale!" Yang Feng instinctively activated this spell, and his body was instantly covered with black dragon scales, protecting his body.
Chapter completed!
