As soon as he finished speaking, a light source with a diameter of ten meters suddenly appeared in the sky. After a flash, countless fireballs suddenly fell down.

"Bang~"

After the loud bang, the surroundings were a sea of ​​fire with extremely high temperatures. Even the hard ground began to melt, and the zombies within the attack range were instantly turned into carbon slag.

Ling Tian was surprised by the effect. He originally thought that he would have to finish off the enemy, but he didn't expect to burn everything to ashes.

"Wait, if it's burned to ashes, my corpse crystal will..."

Ling Tian's face looked a little off, so he rushed down to check.

"I was scared to death, but luckily everything is fine."

Ling Tian found a corpse crystal from the carbon pile, and his heart finally settled down.

Take advantage of the arrival of the second wave of zombies to quickly clean up the battlefield.

Half a minute later, Ling Tian was forced to interrupt the search as hundreds of zombies were approaching.

He returned to the top of the pile of rocks and shouted to the zombies below, "Exploding Meteor Drop...?"

"Exploding Meteor Drop!"

“……?”

For several times in a row, not to mention the falling meteors, there was not even a Martian hat, which made Ling Tian very confused.

"Isn't it said that a Level 2 Psychic can use this ability three or four times? How can this be? Is there a cooldown on this skill?"

In order to prove his guess, Ling Tian took out a compound bow and used it with his flash skill, but he didn't expect the effect to be so good.

As the proficiency in the use of it increases, it can be said that one arrow kills one, and the speed is not slower than the group attack. However, the energy consumption rate is much faster.

"Looks like I need a good cold weapon. A compound bow is good, but it consumes energy."

After five or six minutes, hundreds of zombies had fallen to the ground at Ling Tian's feet, but the number of zombies continued to increase. If he couldn't use his group skills, they would have to escape. He had consumed nearly half of his energy in just a short while.

After trying twice more, he still couldn't use it, and Ling Tian became a little annoyed.

Finally, when his energy was almost depleted, he used the group attack skill again. With the appearance of a huge bright light, the pile of corpses below that looked like a small hill and hundreds of zombies were directly carbonized.

Ling Tian was overjoyed. He continued to hunt down a few restless zombies outside and then jumped into the charcoal pile to explore.

One, two...

The discovery of each corpse crystal was always a joy. Ling Tian was multitasking, searching while on guard, ready to flee at the slightest sign of trouble. Now he only had a sliver of energy left to escape, leaving him with only a few uses for his compound bow, let alone his group attack skills.

After a short while, another fearless zombie appeared. Ling Tian didn't dare to go on and hurried back to recover his energy.

After a few flashes, Ling Tianren appeared several hundred meters away. He now had little energy left. In order to prevent emergencies, he could not use it recklessly before recovering.

Ling Tian did not continue to use his skills to escape. He took out his off-road vehicle and hurried on. Just like last night, he drove the car several kilometers away from the cave before walking back.

After returning to the cave, Ling Tian was surprised to find that his energy had recovered by about 30%. This made him excited, but he immediately fell into deep thought.

"Ye Fan's memory records that it is very slow to recover energy on one's own. Why can I recover so quickly?"

It’s a pity that Ye Fan’s accumulated memories are a bit too little, and he can’t get the answer he wants, which makes Ling Tian’s desire to go to the Bloody Base even stronger.

"Let's get more corpse crystals first. I didn't expect this thing to be such an important currency in apocalyptic transactions."

Through the memory points, Ling Tian already knew that in addition to being used to improve abilities, corpse crystals also had an important function as circulating currency, which could be used to purchase the required items through fixed resource trading stations. Of course, spirit crystals also had this function, but no one would use them for shopping, as they were a necessity for upgrading.

"Resource trading station? I want to go take a look."

"It's better to save up some Corpse Crystals first, otherwise you'll be confused if you don't have enough Corpse Crystals to buy something you like."

After taking a shower and eating two roast goose leg lunch boxes, Ling Tian began to rest. He was very tired after working all night, not only physically but also mentally. After a while, the cave was filled with the sound of snoring that shook the mountains.

When he woke up the next day, Ling Tian found that his body was full of energy. This recovery ability was really amazing. This way he could save a lot of corpse crystals.

After breakfast and feeding the poultry, Ling Tian took out the corpse crystals he had obtained yesterday and counted them. He was shocked to see that there were 53 of them. If he hadn't had time to search carefully last night, there would probably be more.

Thinking back, he had hunted about 500 ordinary zombies last night. He hadn't expected the drop rate to be so high. According to his memory, the drop rate of ordinary zombies was only about 20-30%. His drop rate was more than 10%. Surprised, Ling Tian began to doubt himself, "Could it be that I have a European Emperor physique?"

This is a good thing, don’t think too much about it, the higher the drop rate, the better.

Ling Tian took a corpse crystal and began to swallow it. As soon as it entered his mouth, he couldn't help but shiver twice with comfort. Although he had experienced it twice before, he still couldn't stop eating it again.

After swallowing 30 of them in succession, Ling Tian felt that the enhancing effect of the corpse crystal was gradually decreasing. At the 50th pill, the effect of the corpse crystal was completely lost, and he also reached the peak of the second level. As long as he obtained the spirit crystal, he could successfully break through to the next level.

"Ordinary corpse crystals are no longer effective on me. I'll use them to exchange for supplies so I can go to the Devil Valley to get higher-level ones."

This was the information he obtained from Ye Fan's memory. The Devil Valley was on the other side of the Blood Crystal Mountain and was controlled by several major bases such as Bloody. If you wanted to enter, you had to pay an entrance fee. This fee was of course corpse crystals, and the amount was staggering. You had to pay 500 ordinary corpse crystals for each entry, and you had to pay 30% of all the gains inside. It could be said that it was exploitation.

But there's nothing you can do about it, because they have bigger fists. You can also choose not to go and look for ruins to spawn, but the chance of encountering high-level zombies is too low, and there is no guarantee that high-level corpse crystals will be dropped.

Corpse crystals are divided into four categories: ordinary, superior, top-grade and perfect. Ordinary zombies can only produce ordinary corpse crystals, while zombies at level one and above have a chance to drop corpse crystals of any level, but the chance is pitifully low.

What Ling Tian was very interested in was the third-level zombies. Information showed that zombies of level three and above would definitely explode corpse crystals. However, zombies of this level were no worse than third-level psychics, and their combat power was even stronger, making them more difficult to hunt.

"You're overthinking it. Let's be more pragmatic and go get some corpse crystals."
