Chen Feng returned to the City of the End, and without even having time to greet anyone except Bonnie, he hurriedly came from the pet house to the underground world.

In fact, he and Bonnie didn't meet either. However, now Bonnie's spiritual power has covered the entire City of the End, just like an invisible net over the city, and any existence that enters the city must be scanned by Bonnie's mental power.

It's a security network that's better than modern technology.

Chen Feng even wanted to give Bonnie a nickname, called [Umbrella]. Of course, this is just a nasty idea.

After entering the underground world, Chen Feng walked all the way to the depths, and finally stopped in an extremely empty square, which was the place where he and the lightning emperor sandworm were better.

The surrounding walls are inlaid with some everlasting lamps developed by Charlie, which only need a few

In the future planning, it will be a transportation hub and civic square for the underground world.

"Why haven't you come back yet?"

Chen Feng looked at the depths of the dark tunnel, anxious. Although he could share his vision with the lightning, the lightning was now in the stomach of the imperial sandworm, so Chen Feng couldn't judge their location.

10 minutes, 20 minutes...... Half an hour passed.

Finally, in the depths of the tunnel, there was a slight tremor.

"It's coming!"

Chen Feng perked up, stretched his neck, and tried to look deeper. He was really a little excited about the treasures he took out of the ruins.

Sure enough, the figure of the imperial sandworm gradually became clear. Like a train, it got closer and closer, and finally stopped in front of Chen Feng.

Chen Feng stretched out his hand and pressed it on the head of the Emperor Sandworm and praised, "Earth Dragon, well done!" ”

The Imperial Sandworm squirmed for a moment, expressing joy, and then shook its head, signaling that it was about to open its mouth.

Chen Feng hurriedly retreated, so as not to be accidentally injured by his pet, and the joke was big.

I saw that the mouthparts of the imperial sandworm opened in all directions, and then a row of giant worker ants walked out of it.

The giant worker ant led by him was holding two medium-sized energy columns, and Chen Feng immediately took them and put them away and patted the head of the giant worker ant.

The worker ants in the back were holding miniature ability fragments, mysterious regular hexagonal metal blocks, metal containers containing two fragments of genes, and two small balls, one purple and one green.

These treasures were all seen by Chen Feng with his own eyes, although the medium-sized energy pillar was not included, but it was also expected by Chen Feng, and it was not a surprise.

What he was most looking forward to, and most curious about, was what the treasure was on the sixth high platform before.

The giant worker ants all came out, and it was clear that the treasure was in the hands of Lightning, and it was hidden out of sight.

"This cat, why hasn't it come out yet, playing hide and seek with its owner!?" The lightning never came out, Chen Feng was so anxious that he almost couldn't help but go into the stomach of the sandworm to pull the lightning out, but after looking at the environment in the body of the emperor sandworm, forget it!

Huang Quan saw that his master was in a hurry, so he shouted inside.

When the lightning heard this, he immediately didn't dare to make a mistake, and took the last treasure and walked out of the stomach of the imperial sandworm.

It turned out to be a beautiful mask!

Chen Feng picked it up directly, it was extremely light, and he almost didn't feel the weight, and what was even more amazing was that the mask that was originally golden-colored turned a mysterious purple the moment Chen Feng picked it up.

"Wow!" Chen Feng was also a little surprised, sure enough, the things in the ruins could not be explained by the current scientific level of human beings.

This mask is very delicate, only half the size of a face, and it is better to describe it as a "mask" or "blindfold" than a mask.

"What's the use of this? Can it be placed so carefully on the high platform of the ruins as one of the six treasures of the finale? Chen Feng thought about it and simply brought it to try.

This mask looked a bit small for Chen Feng, and Chen Feng just had the idea of trying it out, and didn't care. But the moment it was attached to the skin of Chen Feng's face, the shape of the mask also underwent subtle changes, becoming extremely suitable for Chen Feng's face shape.

After putting on the mask, Chen Feng's temperament changed instantly, under the background of purple, like a mysterious night king, with a kingly atmosphere in every move, noble and elegant.

But that's just on the looks.

After Chen Feng put on the mask, a cool air instantly poured into his brain, his spirit became extremely sharp, and his mental power instantly doubled.

All of a sudden, the whole world became clearer and more real, and all existence seemed to be invisible in front of Chen Feng's eyes, and he could even calculate the area of dirt under his feet.

If Chen Feng could process 100 pieces of information at the same time before, then after putting on a mask, he can easily process 200 pieces!

To put it simply, Chen Feng now feels like a supercomputer in his brain!

Three seconds passed, and Chen Feng took off his mask with a shocked expression.

This mask is too strong for the increase in spiritual power! It is a treasure of ruins!

However, compared to himself, Chen Feng feels that Bonnie is the real owner of this mask! Come to think of it, Bonnie's current mental power has reached the base of the [Umbrella], and after adding the mask amplification, it will not only expand the area of the umbrella, but also become the sharpest sword!

Just imagine, after the enemy enters a range of thirty kilometers outside the City of the End, he will be locked by Bonnie, and then directly strangled with powerful spiritual power! Even until death, the target cannot see the shadow of the attacker, which is how powerful.

It's a sword of Damocles hanging over the heads of all enemies!

Chen Feng made up his mind and gave this mask to Bonnie. Immediately, he reached out and touched the back of Lightning's neck, "Lightning, you did a good job this time, what reward do you want?" ”

"Meow—"

Lightning stretched out a long lazy waist and ignored Chen Feng.

"Yo, I'm so proud." Chen Feng smiled, he had already appreciated Lightning's arrogance. With that, he shifted his gaze to the two small balls, one purple and one green.

As for the two fragments of genes, Chen Feng was not in a hurry, and was ready to make a genetic leap together with the two drops of the apostle's blood!

Wait a minute.

At the moment when Chen Feng was about to open the purple ball, he found that Lightning's lazy waist had not yet been stretched, and it didn't look like it could be finished in a short time.

"That's not right! Lightning This is in ...... Evolve! ”

Chen Feng suddenly realized that after experiencing a raider of the lost ark operation, Lightning unexpectedly reached the conditions for independent evolution.

"What will it evolve into?" Chen Feng was looking forward to it, but soon, the change in lightning made him dumbfounded, "Stand...... Stand up! ”

I saw that the lightning stretched his waist, his limbs continued to stretch, and then he actually stood upright, and he continued to grow taller.

At the same time, the body and facial features are undergoing this drastic change.

"This, this is ......" Chen Feng couldn't believe his eyes.
