Hundreds of wooden crystals shimmered with crystal light, lying quietly on the palm of Li Fei's hand.

These wood crystals add up to less than five hundred grams, but they exude a large amount of life essence.

Li Fei put these wooden crystals into his pocket, and then ran in the direction of the army.

Many fighters stayed in place, one by one originally restless, after all, no one knew whether Li Fei would encounter danger.

"Commander Li is back!" shouted one of the warriors in a loud voice, and the other warriors looked at him sideways.

The Scaly Horse King finally stopped by the wounded warrior, who insisted on staying and waiting.

"Commander Li, I'm really useless, I almost put you in danger!"

"How can it be, haha, you go to the rear to take care of your body, and then come back and give us Huaxia a fight!"

As the commander of the three armies, Li Fei looked at this soldier and smiled and said, every soldier is very important to him.

The wounded soldier nodded slightly, but his fists were squeezed hard, he would definitely be a good man when he returned from the battlefield in the future!

After sending the wounded warrior back, Li Fei rode the Scaly Armor Horse King and stood in front of millions of soldiers!

"As you can see, there are dangers everywhere in the other world, and you can't be careless at any time!"

Many fighters felt a slight pang in their hearts, and they had to say that Li Fei was not lying.

If you are not careful in another world, it may be your own life that you use to pay for it, which is definitely not just talking.

"Okay, everyone follow me into the valley!" Finally, Li Fei shouted loudly, there is something he wants in the valley!

More than 100,000 advance troops entered the valley with Li Fei, and the entire valley was quite quiet.

There are also many ice sculptures in the valley, all of which are of the same kind that the abyssal lizards have killed by mistake.

Wisps of cold air spread out in the heavens and the earth, but fortunately, the warriors were full of blood and energy.

If this were an ordinary person, the cold alone would be enough to drink a pot, and you would definitely catch a cold when you go back.

The silence of the valley is inevitable, this was originally the habitat of those abyssal lizards, how dare other creatures come?

But the most conspicuous thing in the valley is the ice-blue vines that grow on the cliffs on both sides.

Ice blue vines fluttered in the wind, exuding wisps of cold air.

"Da Da Da!" Li Fei strode towards those ice blue vines.

In the previous life, these frost vines were discovered, and it was almost two years later, and as for the ingredients that were developed into weapons, I don't know what the year of the monkey was.

"Give me your knife to use!" Li Fei said to a guard next to him, who handed Li Fei a saber in response.

This saber was forged by the army arsenal and weighed a total of one hundred and twenty-eight pounds.

The knife edge was even sharper, and Li Fei picked it up and slashed towards the frost vines.

The force of this knife was so great that even the air was rumbling.

Many of the surrounding warriors widened their eyes, and after slashing down with a single sword, the frost vines did not break in response.

The vine itself only had a white mark, but the cliff behind it already had a ten-inch-deep knife mark, which made many warriors stunned.

"It seems to be as strong as my previous life, although it can't be disassembled, but it is very strong!"

The strong defense of the frost vines made Li Fei nod, this thing is worth a million army to fight for!

As for the Frost Vine Fabrication, there is no need to worry about it at all.

There were thousands of silk threads inside the frost vines, and when the time came, it would be like a silkworm cocoon, and Li Fei couldn't help but have a smile on his face.

"Did you see it? In my hand, these things are called Mu Ling Crystals, which can allow you to easily break through the low-level genetic lock! The top three hundred people who pick frost vines today will be rewarded!"

He pulled out hundreds of wood crystals from his pocket, and the air shimmered with crystalline light.

When many fighters heard this, they were eager to try it one by one!

These things are all good things in Commander Li's hands, what soldier doesn't want them?

After the soldiers let Li Fei see this, he couldn't help but nod slightly, sometimes it is not impossible to increase the enthusiasm of the soldiers through rewards.

"These frost vines can be uprooted! Big guy do a good job!" Li Fei said with a smile at the soldiers.

This time I brought a lot of professional tools, including some specialized stubbers.

Outside the valley, thousands of small carts were prepared, enough to transport these frost vines back to Huaxia.

The warriors then got up in a hurry, and the frost vines were dug up one by one.

It took two days for all the frost vines to be transported back to Huaxia and sent to the Huaxia Research Institute.

On October 5, Qian Bing, an old scientist of the Huaxia Scientific Research Institute of the Eastern Military Region, looked at the frost vines in front of him with reading glasses, and conducted subtle research with a microscope.

The old scientist's face was full of surprise, and he almost wanted to explode into a foul mouth.

Such a delicate cell structure is actually a plant, which Qian Bing can't imagine.

"These things in another world are simply new materials, which can lead the development of civilization in an era!"

Qian Bing said with some emotion, and then continued to study, Zhang Tianyi was also studying the characteristics of frost vines.

Zhang Tianyi finally discovered that the frost vines had an exceptionally good performance in the transmission of spiritual energy, and a new type of armor was quietly born......

On October 8, Li Fei was invited to the arsenal by Zhang Tianyi and others.

"Lao Zhang, I said that I have been waiting for your news for a long time, have you developed a new type of armor?"

Li Fei sat in the jeep and said with a smile.

After receiving Zhang Tianyi's call, Li Fei actually had a bottom in his heart, this Taoist master must have a way, otherwise he would definitely not come to him.

"If I say I can't help it, can't I catch up with you?" Zhang Tianyi said with a laugh.

Li Fei gave this guy a roll of the eyes, and Zhang Tianyi was a workaholic.

Normally, as long as Li Fei didn't look for him, this greasy Taoist priest would soak in the arsenal all day long to develop talisman weapons.

After the arsenal arrived, Zhang Tianyi took Li Fei to the shooting range.

"This is the armor you want to see!" Zhang Tianyi took off his coat, revealing the ice blue armor inside.

The armor was surrounded by lines everywhere, like half of a ghost drawing, pieces of alloy and ice-blue vine silk entangled together.

"That soldier, you cut me with the weapon in your hand!"

Zhang Tianyi said to the guard next to Li Fei, and the guard looked confused.

This is a saber in his hand, but Li Fei did not object.

The guard stepped forward, gripped the hilt of his knife tightly, and slashed hard at the ice-blue armor.

After the whole set of armor touched the knife, a blue light flashed...
