The clue left by the black widow is obviously a setting in the game.

According to the clearance process of the game.

Players have to get two important props.

The first is the tooth of the Mountain Ghost, which is the only prop to open the door of the underground tomb.

The second is the clue that only the black widow knows.

And these two conditions are all hidden.

Fang Tang wants to come now, his luck is really very good.

The tooth of the Mountain Ghost was found by the North Star by accident, and it was taken to the mountain temple as a bone.

The black widow, however, told the secret at the last moment before she died.

It's not just luck, but also because I have been working hard to abide by the principles, so I get such a return.

It's just that. What's the next step?

Fang Tang grabs his head and communicates with Bai Fei quickly.

But there are too few clue parameters to calculate.

At this time, Zuo Chuan came quietly and sighed: "you can't open it. It's a nest built by the queen of insects. It's made of the crystal she spits out after mixing excrement and underground ore."

She speaks very fluently now. Although she still has the Zhejiang accent of 70 years ago, she also has a lot of local accent of Osaka.

Fang Tang turned his head: "do you... Recall the memory of your childhood?"

Zuokawa nodded quietly, extremely sad: "that memory, is my own erase, you, you should not let me remember."

Fang Tang knew that Zuochuan was used as an experiment by his father.

That's a memory I don't want to leave.

Now, zuokawa quietly came up: "my father's research goal is to develop the potential of the human body. It's really a big mistake. Human potential is developed through the brain, which needs precise virus configuration, otherwise the fragile brain of the human body will be destroyed in an instant. He also understood this truth a long time later."

"At that time, in the base tomb, I saw my father have correspondence with a biology teacher named Mr. Wan."

Fang Tang was shocked: "Mr. Wan?"

Zuo Chuan nodded quietly: "even Huang DouWang's adoptive father doesn't know that this Mr. Wan is the genius to guide his father to complete the virus."

"This biology teacher, Mr. Wan, sent my father a complete method of virus experiment. At that time, I didn't understand it. Now I think that this person is not a biology teacher, but a Chinese expert."

"At that time, my father only needed to find suitable materials to operate according to the test method given by Mr. Wan. At the same time, Huang DouWang's adoptive father thought of the uncanny vine of sneaky slope. In this way, they extracted the eggs of moth ants."

Fang Tang read this part of the experiment log completely. He was short of breath: "what letters did Mr. Wan have later?"

Zuo Chuan shook his head quietly: "later, there was no news. My father sent the first batch of protoviruses to Mr. Wan after he developed the mutant bug. That was before the end of the war. The only impression I had was that my father was very happy at that time. He drank wine and told me that he was going to take part in a trial!"

Recalling this, Zuo Chuan quietly frowned: "now it's hard to remember what kind of test it was. My father also said that the test was an ancient test passed on for thousands of years, as if it was called..."

Fang Tang's eyes were wide open: "is... Unlimited challenge?"

Zuochuan repeated, a little uncertain: "not these four words, in the pronunciation of Chinese language, it's more like 'endless trials'!"

They all mean the same thing.

Now Fang Tang can be sure that more than 70 years ago, in the era of war, unlimited challenges may have been carried out in secret.

At that time, there was certainly no live broadcast, and there was no modern technology.

So whether it's endless trials or endless challenges, if it's really a thousand year old inheritance, isn't it true that the underworld behind the scenes existed in ancient times?

He was thinking nervously. Strangely enough, Bai was silent from the beginning.

Zuo Chuan quietly glanced at Fang Tang: "do you want to continue to open this nest?"

Fang Tang came back to himself: "this is my task, the so-called trial task!"

Zuokawa silent bitter smile, bent over, lying on those holes, with a strange rhythm, slowly blowing up.

The structure behind the small hole sends out crisp syllables because of the wind.

Gradually, with the quiet playing of Zuo Chuan, an old tune appeared."What's this?"

"This is a song I learned from my mother in Osaka when I was a child. It's called Xizhao..."

"But silence, isn't this the mother's nest? Why is it this song? "

Zuo Chuan quietly raised his head: "fool, that female worm is the one that infected me. I'm the first human being infected by the virus. The female worm and I can communicate. She uses the nest structure made by my favorite song. Maybe you don't understand that those magic insects actually have the ability of evolution. They are spread out as unconscious viruses. As a whole, using these vines is an intelligent life combination. "

i see.

It's like ants.

Every ant is a worm without wisdom, but in the nest, with the queen as the center, the whole ant group is a life body with wisdom.

Are females 10000 times better than ants?

Therefore, under the control of the female, endless magic insects form a life body with wisdom.

Now this organization is proof!

The fetter of the mother insect and Zuochuan's silence makes her use of a kind of superb wisdom to build her own nest mechanism through human music.

It's subtle.

Because only zuokawa can sing this song quietly, so only she can open the mechanism and enter the mother's territory.

How clever.

The riddle left by the widow's sister is right, but she also heard it from the antique dealer. The pronunciation of the last two words is OK, but the words are different.

It's not "a sound shining in the west", but "a sound shining in the evening"!

At this time, the song of sunset sounds in the cave, and the nest opens slowly.

Zuochuan quietly took Fang Tang's hand and went down.

Countless glittering and translucent light appeared, underground space, are all pieces of beads like gems.

"Are these treasures?"

Fang Tang picked up one, such as jade, crystal clear lubrication, but feel strange.

"It's all Sari!" Zuokawa said something quiet.

Fang Tang was scared to throw away: "relic?"

"Ha ha, in fact, it's the residue left by the human beings who were eaten by the magic insects. Isn't the so-called relic the mineral after the cremation of the human body?"

Fang Tang: these gems are just like the heart of a cow and a chicken. They are accumulated by minerals in the organism.

The bug didn't know how many people it had eaten, and there were so many dead animals. As a result, after the corpses were digested, the residual dregs were vomited out by the devil insects and turned into crystal stones.

But it's certainly not a treasure.

In front, in the deepest part of the narrow cave, a big black insect appeared, which had only one skin left.

Zuo Chuan's silent expression was complicated: "this is the female worm. Just now you killed her people, wasted her brain, and she died."

Fang Tang watched for a long time and shook his head: "but I still don't know what the treasure is?"

The main task is not over.

Zuochuan quietly went up and opened the body of the female insect with a long knife.

Then she let out a yelp.

Fang Tang hurried over and saw something like black sesame appeared in the membranous space composed of a mass of secretions under the body of the female.

"It's like a bug, but it's different!"

Fang Tang is staring at: "these... No, it's damn impossible!"

He almost jumped up.

There is no mistake. These black sesame like things are structural organisms with many special viruses.

And this kind of virus, Fang Tang is more familiar with.

"Melanosis virus..."

At this time, ear, also came the system's congratulations.

[player Fang Tang has discovered the ultimate treasure of the game, the evolved melasma virus. When the main task is completed, the player will be rewarded 30000 game coins!]

[primary game, A-level level of stealthy slope, this is the end!]

[player's remaining game currency 50000!]

Fang Tang can't hear these hints, he has straight fainted.
