There is a high platform made of hard stone in the center, with an iron box on it.

In addition, the cave is empty.

Chen Beichen quickly scanned the environment in the cave.

"Well, there is no danger!"

Chen Beichen nodded slightly.

He walked to the high platform a few steps, looked at the iron box in front of him, and the sound of a prompter sounded in his mind.

[Iron Treasure Box: One level higher than the wooden box, there is a low-level spirit stone inside, and there is no danger.]

Chen Beichen nodded slightly and opened the iron treasure chest in front of him.

Sure enough, a crystal clear spirit stone lies quietly inside.

Chen Beichen put it away.

【System Reminder: Low-level Spirit Stone 1】

"System, break down the iron box and these hard rocks!"

Chen Beichen looked at the iron box in front of him and the high platform made of hard stones, and silently recited to the system.

【System reminder: Ling Iron 4】

【System Reminder: Hard Rock 10】

A white light flashed, and the iron box in front of me turned into four spiritual irons. The platform made of hard stones disappeared, turning into ten hard stones.

Chen Beichen smiled slightly and waved his hand gently. He received the spirit iron and hard stone into the base.

After looking around for a week and confirming that there was nothing missing, Chen Beichen was preparing to dig a new cave. He walked under the wall in front of him in a few steps.

【Dig forward, there is a silver treasure chest inside, but you must be careful of the nest of worms inside, and never be bitten by them, otherwise you will be poisoned.】

"Mint Berry?"

A trace of surprise flashed across Chen Beichen's face, and he didn't expect to encounter this thing so soon in this life.

He recalled information about the Yin borer in his mind.

Yin borer, this is a poisonous insect that lives in the darkness. This kind of insect is not very big, and it is not difficult to deal with one or two.

But they are generally in groups, so it will naturally not be easy to deal with.

Once bitten by a bug, its poison will quickly paralyze the enemy and slow down. In this way, naturally, few people can escape from the group of worms.

"Although there is a silver treasure chest, the risk is too great. Let's take a look at something else!"

Chen Beichen shook his head secretly. If there were too many worms in the Yin Dynasty, even with his current cultivation level, it would be better not to provoke them.

The road behind was the way back, so naturally I couldn't go back, so Chen Beichen checked it one by one on the other four sides.

[Digging to the left, there is a silver box monster inside. If you don’t want to make you look sexy, don’t choose here.]

[Dig to the right, there is a spiritual spring inside, but you have to be careful of the three-eyed purple frog inside, it is its territory.]

[Digging upwards, there is a copper treasure chest inside. In addition to the treasure chest, there is also a zombie tyrant. This is a level 3 zombie. If you don’t want to be injured, don’t choose here.]

【Dig downwards, there is an ice and snow cave inside, and there is a silver box inside, but you have to be careful of the iceberg and snow monster inside.】

“Disrection everywhere?”

Chen Beichen was a little confused. This was the first time he had encountered such a situation.

Now Chen Beichen must make a choice. Obviously, he will pass it directly to the left cave, and there is nothing but the silver box monster inside.

After eliminating a useless one, he must choose the monster he wants to face.

Yin borer?

No, there are too many of this, so I won’t be able to capsize in the gutter and eliminate it directly!

Zombie Tyrant?

This is a level three zombie, equivalent to the level of a master in humans, but this thing is much more powerful than a master because it does not know the pain and is not afraid of death.

It's a bit unprofitable to fight hard with just a copper treasure chest.

The rest are the three-eyed purple frog to the right and the iceberg snow monster to the downward.

Chen Beichen recalled information about these two monsters.

The three-eyed purple frog, as the name suggests, is a monster full of purple and three eyes. Its power lies in one of its purple eyes.

It is said that its third purple eye can emit a strong light that can cause a brief blindness. With his poisonous tongue, I believe that not many people are its opponents.

The iceberg and snow monster in the ice and snow cave is said to be shaped like a snowman. It is not only powerful but also has ice-type spells, such as ice thorns, ice shields, etc., and is even more like a fish in the ice and snow cave.

The threats these two monsters are almost the same to them, so it depends on what is inside.

Facing the three-eyed purple frog, you can get the spiritual spring. This is a good thing. With your current strength, you should be able to bring all the spiritual spring water into your own base.

When facing the iceberg and snow monster, you can get the silver treasure chest, but you don’t know what is inside the silver treasure chest.

Thinking of this, Chen Beichen chose a corner and quietly waited for the sound of the prompter.

【Dig downwards, there is an ice and snow cave inside, and there is a silver box inside, but you have to be careful of the iceberg and snow monster inside.】

Chen Beichen silently said, "What is inside the silver treasure chest?"

After a while, a message appeared in Chen Beichen's mind.

It turned out that there was a volume of martial arts and an intermediate-level spirit stone in the silver treasure chest.

After obtaining this information, Chen Beichen made a decision instantly.

That is digging to the right.

The value of a spiritual spring is much more valuable than that of a mid-level spirit stone, and Chen Beichen does not lack martial arts skills.

In addition, the magical power of the third purple frog, the three-eyed purple frog, does not pose a threat to Chen Beichen, the only thing to pay attention to is its poisonous tongue.

With this analysis, killing the three-eyed purple frog and obtaining the spiritual spring is your best choice.

Chen Beichen is not his mother-in-law. Since he has decided, he naturally has to start making some preparations.

First, upgrade your equipment. Chen Beichen pondered for a moment. He was about to upgrade the Youlan Gun in his hand.

Chen Beichen looked at the conditions for upgrading the intermediate spear.

[Materials required to upgrade the second-level orchid gun: Lingmu 5369/20, Ling iron 7/20, Ling copper 14/20, Low-level spirit stone 4/20, Alchemy 13/10, Crystal core 2/1]

Chen Beichen frowned, there are still some materials missing.

After thinking about it, he put some materials that he could not use for the time being on the trading platform.

In addition, he took out the wooden barrel and decided to continue selling water.

Soon, he pinched a handprint, and balls of water began to gather in the wooden barrel. After a while, the 2L bucket was filled.

Seeing this effect, Chen Beichen nodded slightly. It seemed that as his cultivation level improved, the difficulty of creating water was also reduced.

At this time, he thought for a while and said, "System, put 2L of water on the shelves, exchange for spiritual iron, spiritual copper or low-level spiritual stones."

Trading platform.

【Seller: Mo Ye】

【Trade Products: 2L Water】

【Requirements: 1 Low-level Spirit Stone】

【Alternative: 20 spiritual iron or 10 spiritual copper】

【Inventory: 1】

【Note: If you have products, please chat privately]

Chen Beichen looked at his spiritual wood and hard stones and said, "System, spiritual wood and hard stones have also been put on the shelves for me in exchange for low-level spiritual stones, spiritual iron and spiritual copper."
