The requirements of manufacturing ordinary tools like this can meet the basic manufacturing functions of the system.

And it is not so easy to make a real armor, just like Chen Beichen's orchid gun, which requires drawings.

As long as there are drawings and materials, any system can be manufactured.

After looking at his second-level Youlan Gun, although he had already been upgraded to one level, this was not enough. Chen Beichen was preparing to upgrade his Youlan Gun.

He looked at the materials needed for the Youlan Gun to level three.

[Materials required to upgrade the third-level orchid gun: Spirit Iron 197/50, Spirit Copper 33/50, Spirit Silver 4/20, Spirit Gold 4/10, Low-level Spirit Stone 47174/1000, Alchemy 3/50, Spirit Core 1/1]

【Note: Special materials can be added】

"It shouldn't be difficult to put together these materials now, but the spirit gold may not be enough."

Chen Beichen thought: "System, search for trading platforms, replace the materials I need!"

Soon, the system replaced the materials that were missing from the upgrade.

[System Reminder: Spirit Stone-589]

Chen Beichen thought it might not be easy to get all the spiritual gold, but he didn't expect it to get all the gold.

Has anyone else opened the treasure chest besides me?

Chen Beichen was very confused about this. He opened the transaction record and wanted to see where the system bought the spiritual gold.

Soon, a name appeared in Chen Beichen's eyes - serving the country with loyalty!

It turned out to be him, no wonder.

Speaking of which, I exchanged the Power Bull Demon Fist with him shortly after entering the underground cave for the second time!

According to Chen Beichen's guess, this loyalty to the country should be a national war god-level figure.

God of War, this is the strongest warrior in the country to the outside world. I heard that at least people at the level of a grand master can become God of War!

Shaking his head and not thinking about this, Chen Beichen opened the interface to upgrade the Youlan Gun.

[Materials required to upgrade the third-level orchid gun: Spirit Iron 197/100, Spirit Copper 50/50, Spirit Silver 10/20, Spirit Gold 10/10, Low-level Spirit Stone 46585/1000, Alchemy 50/50, Spirit Core 1/1]

【Note: Special materials can be added】

"System, add spiritual glue to special materials!"

【System Reminder: Lingjiao-50】

"I didn't expect that the Ice Spirit Core will be used so soon. System, please upgrade the Youlan Gun!"

Seeing that the spirit core that had just been obtained was about to disappear, even Chen Beichen felt a little heartbroken, but it was more important to upgrade the Youlan Gun, after all, this is his own weapon.

As Chen Beichen finished speaking, the orchid gun in front of him was wrapped in a layer of dazzling white light, making it impossible to see what was happening inside.

About ten seconds later, the white light in front of me disappeared.

Obviously, compared with the three or four seconds of the last upgrade, the Youlan Gun was upgraded even slower this time.

At this time, what appeared in Chen Beichen's hand was a pitch-black spear. It was deeper than before, and it was obviously because of the addition of spiritual glue.

In addition, the pattern engraved with dark gold on the gun is even more mysterious and complicated.

What's even more strange is that the tip of the black spear is red and blue, but the blue seems to be a little more, making it look charming and weird!

Looking at the obviously different spear in front of him, Chen Beichen tried to inject a trace of spiritual energy into the spear.

In an instant, the spear in front of me seemed to have come alive, and the dark golden patterns on the gun rod were floating on the spear like living things.

"drink!"

Chen Beichen picked up the spear in his hand and stabbed it casually, and a blue-red spear light appeared on the tip of the spear.

"boom!"

A huge pit was blown out of the ground in front of me.

"I didn't expect that the combination of ice attributes and fire attributes would actually have an explosion effect!"

Chen Beichen nodded secretly, believing that this explosive skill can surprise the enemy at a critical moment!

After everything was ready, Chen Beichen began to wave his waving in a black anti-electric clothing, holding a gun in his left hand and a "ordinary" shovel made by the system in his right hand.

Soon, the cave on the left was dug up, revealing the familiar black light curtain.

Chen Beichen took a deep breath, put away the shovel, and stepped into the black light curtain.

...

As soon as Chen Beichen entered, he found that there was only a Thunder Mountain thousands of feet high in the cave in front of him.

Although this Thunder Mountain occupies not as big as a jungle cave, a mountain is still very large compared to the size of an ordinary person.

The most eye-catching one is that at the top of the mountain, there is a faint white light flashing, and accompanied by a loud "rumbling" sound, countless thunders are flashing.

The thunder on the top of Thunder Mountain never stops, and seems to be invincible forever!

Every time the thunder sounds, it makes the entire cave as bright as day.

This is also the first time Chen Beichen has encountered such a bright underground cave. The brightest cave I encountered in front is not as bright as the Thunder Mountain Liang in this cave.

In addition to the thunder on the top of the mountain, this Thunder Mountain has another wonder.

That is, there is a lush forest at the foot of the mountain, with shrubs and grass up one hundred feet, and sparse weeds over one hundred feet.

Going further up, you will gradually reach the ice field and snow, and thousands of feet close to the top of the peak are flashing with faint white lightning, and there is no ice and snow.

From bottom to top, it is dark green, yellow-green, withered yellow and white.

Thunder Mountain, a thousand feet high, is tens of miles deep in the forest at the foot of the mountain.

The trees in this forest are extremely tall. The giant trees that are embraced by seven or eight people can be regarded as tree kings when placed in ordinary forests, but at the foot of this Thunder Mountain, they are only ordinary trees.

Soon, Chen Beichen and others jumped to the foot of Thunder Mountain.

Suddenly, a series of prompt sounds sounded in my mind.

[Thunder Mountain: This is a magical mountain with dragon eggs on the top of the mountain, but you must be careful of its guardian - Thunder Lizard!]

Chen Beichen raised his eyebrows slightly, but he didn't expect that the prompter could even prompt the situation in this mountain.

He slowly recalled information about the Thunder Lizard.

Immediately afterwards, Chen Beichen learned from a series of prompt sounds that at the foot of Thunder Mountain, there were very few Thunder lizards, and a few were also impure in blood.

These lizards are covered with white scales and spit out white lightning, and their strength is equivalent to warriors of fourth or fifth level torture.

The higher you go, the stronger the Thunder Lizard becomes.

When we arrived at the mountainside, the scales of the thunder lizard turned red and the mouth was spitting red lightning. The strength of the red thunder lizard was equivalent to that of the eighth and nineth level warriors in the body.

Further up, there is a blue lizard, equivalent to a warrior in the innate realm.

When you reach the top of the mountain, there is the Purple Lizard King, who is equivalent to a master warrior!

Seeing this, Chen Beichen's face showed a little surprise. Unexpectedly, the Thunder Lizard Clan was hidden on the thunder mountain in front of him.

However, this could not scare Chen Beichen, so he was still ready to go up and take a look.
Chapter completed!
