Thinking of this, Wu Mo immediately began to prepare.

He put on the heat-insulating gloves and poured the molten iron in the crucible back into the furnace. Then, he immediately placed his hands near the fire exit and controlled the flame in the furnace to roast the molten iron.

As he injected the mental power in his mind into the furnace bit by bit, the temperature of the flame began to rise.

Soon, the color of the flame, which had exceeded 1,500 degrees, gradually changed from red to orange.

The molten iron inside slowly boiled up, and a lot of impurities were removed.

However, at this rate, it would take at least three days to remove all the impurities in the molten iron. However, Wu Mo did not have that much time to waste, so when the temperature reached 1,700 degrees, Wu Mo abruptly transferred his spirit power at a faster pace!

Tonight, he had to at least forge the prototype of Thor’s hammer. If he kept delaying this, there would be no time.

His hands trembled slightly, and he stared at the red flame through the fire.

As the temperature rose, the metal on the surface of the furnace was roasted until it was red, as though it had reached its limit.

“This temperature is simply not enough!”

Wu Mo gritted his teeth. He wanted to break through the temperature ceiling and strive to purify all the molten iron within an hour.

In the complicated steps of forging, the purified materials were only a small part of it. He had to leave enough time to cast the prototype for Thor’s hammer after purifying the molten iron.

Time gradually passed, and Wu Mo felt a little dizzy as if he had used up more than half of his spirit power.

If he continued, he might lose consciousness due to the exhaustion of his spirit power, and the system might force him out of the forging space.

He did not want to give up just like that, so he planned to hold on for a few more minutes.

Enduring the dizziness, Wu Mo injected his spirit power into the furnace again. Using his spirit power as the raw material, he raised the temperature of the flame again!

The molten iron in the furnace began to boil intensely, and many gray impurities were separated. Then, they were turned into ash by the flame and expelled.

Just as Wu Mo was about to give up, he suddenly heard a voice in his mind.

[The host’s spirit power has reached the required standard. The furnace has met the requirements for upgrading. Upgrading to the Premium grade requires 1,000 points. Would you like to upgrade?]

The voice that appeared in his mind distracted him. At that moment, he was already on the verge of a mental breakdown. He even subconsciously thought that the voice in his mind was a hallucination caused by his fatigue.

His footsteps were light. Wu Mo slowly lowered his hands and immediately chanted in his heart, ‘Backtrack!’

He knew that his current state was very dangerous. The system could force him out of the Divine-grade Forging Space at any time due to the exhaustion of his spirit power.

Moreover, he did not have the energy to think about the information he had just received. For the sake of safety, Wu Mo made his move.

Following a flash of white light from within the furnace, the boiling hot metal returned to its solidified state. Wu Mo’s unconscious state also disappeared completely, and his gaze became bright and spirited. There was no sign of fatigue at all.

[Backtrack successful…]

Wu Mo lowered his head to look at his slender fingers. He felt some lingering fear in his heart. If he had reacted a little slower earlier, he might have already been forcefully kicked out.

Thinking of the system voice he had heard before, Wu Mo immediately summoned the system panel in his heart.

Looking at the light blue panel that appeared before him, Wu Mo opened the notification panel. He realized that when his mind was chaotic just now, the system had given him three notifications.

The first one was about upgrading the furnace, while the second and third one was about the influence points of the Armor-piercing Short Staff and the Mercury Cloak.

[Six hours of influence points calculated. The Armor-piercing Short Staff, a piece of Rare-grade equipment, has a greater influence on the outside world. It directly affects 327 people and indirectly affects 2,870 people, gaining a total of 2,304 points.

[The Premium-grade equipment, Mercury Cloak has a great impact on the outside world. It directly affects 341 people and indirectly affects 3,118 people. A total of 3,726 points have been obtained.]

When Wu Mo saw the points obtained from the two pieces of equipment, his heart was filled with excitement. Points could be exchanged for many rare materials and even finished equipment in the system’s store. On top of that, he could also upgrade various components in the workbench.

His two pieces of equipment had actually earned him a total of 6,032 points. These points were enough to exchange for an Epic-grade rare material or excellent Premium equipment.

It was a free benefit for Wu Mo!

“It appears that to get more points, the number of spectators must be enough,” Wu Mo rubbed his chin and muttered to himself.

He remembered the last time he took out his Interspatial Ring in Treasure Pavilion’s courtyard, there were only a dozen people around him. In the end, he only received 184 influence points.

Through the comparison of these several sets of data, Wu Mo could roughly guess that the influence points should be related to the number of spectators and the effect of the equipment.

The more people present, the higher the points he would receive. The better the grade and effect of the equipment, the more people would be in awe.

Reaching this point, Wu Mo could roughly understand the composition formula for influence.

[Would you like to use 1000 points to raise the quality of the furnace to Premium grade?]

The system did not hear Wu Mo’s reply earlier and asked mechanically.

“Yes!” Wu Mo immediately replied.

The next moment, the furnace before him was suddenly enveloped by a green light, and a string of numbers was suspended on it.

[300 seconds to upgrade completion.]

When Wu Mo saw the string of numbers, something dawned upon him.

He pulled up the system interface and found that in addition to the store and personal attributes, there was an additional interface for the management of the workbench.

Wu Mo opened it and found that in the workbench’s interface, there was an illusory design blueprint. Plus, each position on the design was marked with accessories and functional information.

The workbench, the mold, the furnace, the strengthening table, and so on… There were a total of more than a dozen functional areas, and some of them had been unlocked. Among these modules, only the furnace met the upgrade conditions, and the rest showed that they could not be upgraded yet.

Wu Mo looked at the furnace that was being upgraded, and the system immediately gave him a description.

[The functions of the Premium-grade Furnace are as follows…]

The highest temperature it could reach was 3200 degrees. It had 14 burners and a control precision of about 10 degrees.

It also had the additional effect of saving 25% of the user’s spirit power.

As Wu Mo read the string of numbers in front of him, he felt a little surprised.

He now knew that the workbench provided by the system could be upgraded separately, and the upgraded components would have additional effects.
