Knowing the existence of the big filter, Yang Zhou suddenly had a lot of sense of crisis, and after the cancer crisis was gone, Yang Zhou felt that there was nothing to threaten him on the earth.

It was easy to make money, and no one dared to provoke him.

Even if a foreign pharmaceutical group used some means to assassinate him, it was easily resolved, resulting in the inexplicable death of Black Glove.

If nothing else, then Yang Zhou will definitely develop steadily and steadily, slowly improve the strength of Huaguo Biotechnology, and drive the development of the entire industry.

Eventually get ahead of the rest of the country, and then explore outer space.

Maybe while pursuing more advanced biotechnology, they will also look for ways to live forever, but now it is different.

With the sword of Damocles hanging overhead, who knows if the Great Filter Crisis is a meteorite threat, a virus infection, or an alien invasion of Earth.

If it is the last type, most of humanity does not have much hope of defeating aliens who can cross the galaxy and attack the solar system.

Yang Zhou was a little distracted for the next period of time, and he was thinking about what to do.

How to deal with unknown dangers.

Yang Zhou finally thought of Dave, Dave should have obtained the system much earlier than him, if there is really a big filter, it should be Dave who encountered it first.

"Dave, I just came into contact with a high-level host who told me about the Great Filter Crisis! We have very few level 6 commodities, and there are not many hosts, which is the reason for the big filter, there will be many hosts who can't survive this crisis, how many years are you now, and how long have you been getting the system? Yang Zhou asked.

Dave looked at the message sent by Yang Zhou in surprise.

He didn't expect that Yang Zhou, who had a lower level than him before and knew less information than him, would now actually go ahead of him and come into contact with a more advanced system host.

Dave was a little emotionally complicated for a while, but at the end, seeing the huge crisis that Yang Zhou said, Dave suddenly woke up.

It turned out that his guess was correct, and there were fewer level 6 commodities because there were fewer hosts at this level.

The people who couldn't survive just disappeared.

If the system host also has a large filter, then level 6 to 7 may be a bottleneck, or a large filter, and then level 9 or 10, there will be another bottleneck.

If you think about it carefully, you can understand that before the fifth-level system, the host may be terminally ill, and the strong desire to survive will make the host try his best to upgrade and buy cancer plants.

At level 6, it is basically not threatened by cancer, and the host may slack off at any time.

The system quietly creates a crisis, allowing the host to be vigilant at all times and desperately improve itself.

Dave even felt like the system was raising Gu.

"Yang Zhou, is what you said true? Who told you what exactly is the crisis of the big filter? Dave replied quickly.

Yang Zhou told Dave about his contact with Levi, which was nothing to hide.

However, Yang Zhou developed a level 7 plant at level 6, which made Dave amazed.

You must know that it is very difficult to develop high-level plants, he has been stuck at level 6 for a long time, and he has not created any level 6 plants at all, let alone higher-level level 7 plants.

Ordinary transformation is very easy, Dave can transform tens of thousands of ordinary plants at any time, these plants may be more magical for the living planet.

But for the system, it's not brilliant at all.

"According to history, I am here in 2029, and it is possible that the first crisis is coming, and now I can't find out if there are any meteorites approaching my planet." Dave replied with a headache.

Yang Zhou is worried about himself and Dave, if Dave really dies, is it a verification of Levi's words, 2029 and 2036 are dangerous nodes.

And it's likely that you won't have to upgrade to level 7 to encounter a crisis at all.

Because in this case, there should still be a lot of level 6 hosts, and now they can't be searched, and the goods are also very scarce, and it is likely that the level 6 host will be in danger not long after reaching level 6.

Only very fortunate can a gifted host survive such a crisis.

Dave thought about it a lot, and finally found that there were only 2 possibilities for what Yang Zhou said, or Yang Zhou was lying to him, which was very unlikely.

Because it doesn't make much sense to lie to him, not to mention that Yang Zhou probably also wants to verify what the big filter is.

If Yang Zhou didn't deceive people, then Dave's only lifesaver was Yang Zhou.

Only Yang Zhou can come into contact with all kinds of other plants, and in order to improve his defensive strength, he needs Yang Zhou to help him buy some defensive plants, so that he can have a greater chance of survival.

And he really doesn't lack experience points!

"Yang, I think it's up to you in the future, I'm not afraid to tell you, my experience value is currently over 30 billion, and now I don't think I can wait for you to upgrade to level 7 to buy the World Tree, so I will buy all kinds of plants that can increase my own defense now." Dave said.

Yang Zhou was a little entangled, because selling plants to Dave was not a big problem, that is, to occupy his own stall.

The plants that occupy the stall are like Yang Zhou buying metal vines for iron eggs at the beginning, although the metal vines occupy the stall, they will not be displayed in the mall.

The Marketplace displays only original works.

Of course, others will also see metal vines when they click on Yang Zhou's personal channel, which is the only benefit, and when they meet people who just need a certain plant, even if they know that the goods are much more expensive, they will still choose to buy them.

And this plant can also be upgraded in the future, just like the metal vine was finally upgraded to the sky grapevine, there is a trend towards the development of the space elevator, so the value is very high, and it has finally been recognized by the system mall.

"Okay, if I come across a plant that increases my defense, I will choose to buy it, and then hang it in the stall waiting for you to buy it." Yang Zhou said.

Dave was naturally grateful, he didn't expect Yang Zhou to agree so easily.

Because this is obviously not in line with the development of the host, although you can earn some experience points in the short term, but basically don't want to upgrade, you can't even unlock the gene lock, how to further upgrade.

While grateful, Dave finally put aside all kinds of hypocrisy in his previous past, and sincerely suggested: "Yang, I think you should also consider the route I have taken, after all, this experience point increases very quickly, according to you, I suspect that Levi is also upgraded to advanced through rapid population reduction, and the Zerg development form you mentioned, controlling everyone, isn't this similar to what I am doing now?" ”

"Is the system encouraging us to sacrifice the entire civilization and strengthen our own development?"

Yang Zhou refused without hesitation: "No need, I have level 7 plants, and I can sell plants to you, and sooner or later I can upgrade to level 7." ”

Dave still has some regrets, if Yang Zhou chooses to kill and upgrade, he can quickly reach level 7, contact the level 7 mall and meet more high-level hosts, wouldn't he be able to encounter more magical plants, which is the most beneficial to Dave.
