National Luck: Iron Man, the mechanical army sweeps everything

"Um!!"

After hearing this, Uncle Jiu kept nodding his head and asked:
"You mean, behind the national battlefield, there may be a bigger game of chess?"

Qin Feng raised his brows, "I don't know if there is a bigger game of chess, but it is certain that we are just a chess piece."

"Young master is wise!"

The witch and demon patted a flatterer in the back at the right time.

This is actually not flattering, but a question that he has been thinking about for a long time, but he still can't figure it out, so the young master clarified it.

Who is capable of creating the national battlefield? It's okay if you can't figure it out.

What is the national battlefield for?
He scratched his head on this question and didn't understand it.

Unexpectedly, the young master's words today would directly wake him up.

Isn't it to promote the integration and progress of civilization?

Enhance the combat effectiveness of civilization!

"The zombies on the ground will be handed over to Uncle Jiu."

Qin Feng said.

"Brother Qin, don't worry, even if you are poor, you will never let a zombie enter the country!"

Uncle Jiu twitched solemnly, with a serious look on his face.

Qin Feng: ...is it that serious?

The arrangements on the ground have already been implemented.

A row of zombies stood in front, and Uncle Jiu Suli stood in the back row.

Gupu and Amber are in charge of the two primary defense towers!
With such a configuration, it should be no problem to deal with three zombie kings + 30 zombies.

Seeing that everyone is waiting in full force, Qin Feng is relieved.

On the other side, Sister Bao'er was holding the Spirit Slaying Saber, and all the mechas were fully equipped.

"Okay Jarvis, now I'll number them!"

Sister Baoer stood in front of the five sets of mechs, with the air of a general commanding thousands of troops.

"Yes, Miss Bao'er."

Jarvis was very cooperative with her.

"This Mark3 will be called No. 1 machine from now on, and the two sets of Mark4 will be called No. 2 and No. 3 machines respectively..."

Qin Feng was speechless for a while, thinking that she had some brilliant ideas.

Unexpectedly, it was numbered from the No. 1 machine to the No. 5 machine.

Ta Ta Ta.

More than an hour before the official arrival of the shock, Qin Feng walked towards his studio.

"Young master, what about the old slave's mission?"

Wu Mo doggedly followed behind, nodding and bowing his head as he asked.

"you?"

Qin Feng frowned, there was really no place for him.

"You go to cooperate with Sister Bao'er to guard the gate of the country, and if you let a monster in, you will die!"

After speaking, he entered the studio without looking back.

"what???"

The witch froze in place, as if he had been sentenced to death.

"Less... young master..."

Judging by what the young master meant, he had absolutely no intention of intervening in this attack.

The witch demon's mid-term strength is full of magical powers, but he can't exert half of it.

The main reason is that there is no time for him to recover, and there are less than two hours before the impact.

Is this time counted as time?

He turned his head to look at Sister Bao'er, who was commanding five mechas flying randomly in front of the three gates.

Instantly wanted to die.

"Only rely on this protective cover."

Fortunately for the witch, the gate of the Three Kingdoms was protected by a primary protective shield.

Although it was a primary shield, it was brewed from the aura contained in 5000 units of black iron.

"No, you still have to recover first."

The witch and demon ran out of the gate of the wall pitifully, and stopped to sit cross-legged when they were far away from the gate.

Under the operation of the kung fu, all the surrounding spiritual energy gathered towards it.

It almost converged into a spiritual vortex visible to the naked eye.

The aura is breathed out by the witch and demon, and all of it is transformed into magic energy.

Feeling the replenishment of the long-lost magic energy, the witch and demon slowly exhaled a mouthful of turbid air comfortably.

The people in the country who were preparing nervously were speechless when they saw this vision of heaven and earth.

"Worthy of being a strong man in the middle stage of magic magic!"

Uncle Jiu muttered.

"Master, what magic spell?"

Suri asked.

The rest of the people also gossiped and eavesdropped.

Uncle Ninth naturally gave everyone science popularization.

Sister Bao'er was suspended in the air, looked at the spiritual vortex and praised:

"This baby is really fierce!"

Qin Feng, who entered the studio, asked:

"Jarvis, what happened to the printed nails?"

For the past two days, the machines in the basement have not been idle.

According to the combination and ratio of the three materials, Jarvis has been printing experimental nail pieces and testing their hardness.

Qin Feng's favorite new armor piece is mainly based on protection and aura affinity.

"Sir," Jarvis replied, "There are 1 finished products of all possible combinations of black gold, mithril, and adamantium, as well as 1866% particle size variation ratios, and 1800 formulas that failed the hardness test. The remaining 66 types require you to perform the aura test."

Qin Feng nodded and praised: "Good job."

"Thank you for the compliment, sir."

"Upgrade the remaining 66 experimental items, and use this time to test."

"Yes, sir."

After Jarvis finished answering, the elevator in the basement rose.

Neatly placed on it are exactly 66 kinds of numbered experimental armor pieces.

Qin Feng picked up the first piece, "Start the aura affinity test and make a record."

"Yes, sir."

Qin Feng circulated the aura to bless the nails.

Suddenly, the studio was full of aura.

About an hour and a half later, all 66 nail pieces were tested.

"Sir, the formula numbers that you are satisfied with with the Aura Affinity are as follows: ETA673, ETB012, ETB035."

Qin Feng stood up and stretched himself.

"The ratio of these three formulas is reduced from 1% to 0.05%, and then experimented."

"Yes, sir."

Among the three formulas, fortunately, they are only alloys of two materials.

They are Ugin: Mithril=93%: 7%;

Wujin: fine gold = 27%: 73%;

Mithril: Fine Gold=87%: 13%.
Now you only need to use these three ratios, and then reduce the ratio accuracy of the alloy to 0.05%, and you should be able to find a more suitable alloy formula!

"Golden Ridge Divine Sand?"

With the sound of the basement starting to work again, Qin Feng took out the 'big iron chain' obtained in the mine.

"I don't know how effective this thing is for making nails."

After muttering, Qin Feng took the shortest paragraph in his hand.

This is when the witch was released, and a lot of energy was spent to blow it off with a laser.

"I don't know how effective it is to smelt the puppets."

He ran the formula, and a short piece of large iron chain in his hand began to rotate slowly.

However, after about ten minutes, the big iron chain was only a little red.

It is not easily smelted to extract the essence like other E-grade materials and D-grade materials.

"Jinling Shensha, is it really more high-end?"

Qin Feng muttered and gave up temporarily.

Or because my realm is too low, it takes a lot of time to produce materials of this level!
At this moment, the reminder of the national battlefield sounded again.

[Battlefield reminder: The last minute of the fourth wave of impact, all defenders, please be prepared. 】
