I moved my body around and found that after the complete mutation, not only had my strength been greatly improved, but my body's defense capabilities had also been greatly enhanced.

After a careful comparison, I realized that I am many times stronger than before. If it is a life-and-death battle, I can easily kill my before in seconds.

It turns out that this is the power of mutants. No wonder so many people tried so hard to mutate before. With the strength after mutation, they can indeed survive on the island.

After the mutation was completed, I found that I had a more important task, which was to enter the underground palace according to the instructions on the map.

Because I know very well that even if I mutate successfully, I need to become stronger if I want to survive on this island.

Based on the importance those people attached to the map before, I can imagine that there must be something in the underground palace that can help people become stronger.

What I need to do now is to enter the underground palace first before those people react, find those things that can make people powerful, and make myself stronger.

After the mutation was completed, the journey that originally took more than an hour now only took me half an hour to reach the big tree where the underground palace was located.

Following the instructions on the map, I quickly found a hole next to a big tree. The hole was pitch black and I couldn’t see the bottom at a glance.

This made me wonder what was inside the underground palace? It actually made those people spend so much money to build such a large underground palace on the island to preserve such a thing.

But at this moment, in order to survive, I didn't care about the fear in my heart. After thinking for a while, I slowly walked into the deep cave.

I was previously shielded by a wooden board, but over time, the board had rotted away, allowing a lot of fallen leaves to fall into the passage.

A rotten and foul smell came into my nose. I knew that it was the smell of rotting deciduous trees because no one had been in the passage for a long time.

For this reason, he had to exit the cave, find a thick wooden stick outside, and constantly push the fallen leaves on the ground, slowly moving inside.

Having lived on the island for such a long time, I knew very well that there might be some poisonous insects hidden in these fallen leaves.

The venom of some of these poisonous insects is very strong. Even though I have successfully mutated, some of them can still pose a threat to me.

For the sake of my own life, I had to adopt this method of advancing in a way that would alert the enemy, even though the speed of advancement was very slow.

During this process, I had to thank my previous experience of surviving on a desert island, which taught me how to remain patient.

Therefore, although this work was very boring, I did not feel impatient at all. I kept fiddling with the fallen leaves on the ground carefully and continued to go deeper into the underground palace.

Sure enough, my stupid method worked. Less than ten meters ahead, two colorful poisonous snakes crawled past me.

In order to avoid future trouble, I pulled out the long knife on my back and decisively cut the two poisonous snakes into two sections.

After cutting off the poisonous tongue, I still didn't dare to be careless. I used the long knife in my hand to stab the snake's constantly twisting head. After a minute, I dared to ignore these poisonous snakes and continue to move forward.

The reason why I have to be so careful in handling these poisonous snakes is that at the very beginning, I saw someone suffer a great loss from them and paid the price with his life.

Many people think that a venomous snake loses its life after being cut into two parts. In fact, the result is not like this. After the venomous snake's head is chopped off, it can still move freely, and the venom contained in it continues to be retained.

At this time, as long as you dare to enter the attack range of the poisonous snake, it will bite you fiercely without hesitation. The deadly venom contained in it will suffocate you to death within a minute.

When I was first stranded on the deserted island, I saw with my own eyes that someone suffered a loss from this and was completely killed by the venom of the poisonous snake.

Fortunately, the passage leading to the underground palace is not long, only about 100 meters. It took me more than half an hour to finally pass through the tunnel covered with fallen leaves.

In the process, I killed eight poisonous snakes, two big spiders and a giant centipede.

I can be sure that if someone else walked in without any precautions, even if he had been completely mutated, the final outcome would be that he would lose half his life if not death.

Without bothering to recall the feeling of passing through the passage before, I looked at the iron gate in front of me, thinking about how I could get in?

This iron gate is different from the common iron gates outside. I could tell at a glance that the entire iron gate is made of aerospace materials and there is not a single gap at all.

I don’t know who actually spent such a huge amount of money to make an iron door with such expensive aerospace materials. You know, this door alone can be sold at a high price of hundreds of thousands of US dollars outside!

However, the least valuable thing on a deserted island is money. If I could exchange these materials for swords, I would probably be happier.

Since I don’t know how to open the door in front of me, I have to use violence to destroy the door so that I can enter the underground palace smoothly.

I drew out my long sword and slashed it hard on the iron gate. I saw a string of dazzling sparks rising. There was no mark left on the iron gate, but there was a gap left on my long sword.

This made me feel very sad, and I quickly put the long sword back. After all, if I want to survive better on the deserted island, I must have no weapons in my hands.

"Damn, what kind of rotten iron door is this? It's so hard that it almost destroyed the knife in my hand!"

As I said this, I punched the iron gate hard, trying to vent the frustration in my heart.

After all, I spent more than half an hour passing through the passage covered with fallen leaves, but when I reached this end, I was blocked by this big iron gate, which made me feel very depressed.

My fist landed hard on the iron door, but there was no pain as I imagined. A huge groove appeared on the iron door, but there was no scar on my hand.

Looking at the scene in front of me, I couldn't help but be stunned. It turned out that my fist was so powerful that it could easily leave such a big groove on the iron door.

In this case, why would I need a knife? With my fists, I can completely smash the iron door in front of me.

Thinking of this, I couldn't help but get excited. I stopped thinking about the long knife and punched the iron gate hard one after another.

Muffled sounds continued to ring out in the passage, and soon the iron gate in front of me became riddled with holes, with huge fist marks left on it.

I don’t know how many punches I threw, but it seemed like the last straw that broke the camel’s back, and the iron gate collapsed in front of me with a bang.
