Feng looked outside and saw that it was still early and he had people around him.

Since he had to cultivate mycelium sooner or later, he might as well do it now!

He followed the plan given by the system and took out the mother bacteria first. Since it was a system reward, he threw it in his own space warehouse.

Agar is used as a culture medium.

Several smart incubators and air humidifiers are also needed.

He put on a white coat and protective glasses, looking a bit like a technician, and prepared the raw materials.

The temperature needs to be 20-28 degrees Celsius, and Ye Feng took 24 degrees Celsius as a compromise.

The humidity is 80-90%, and 85% is also taken as a compromise.

The pH can be around 7.

Ye Feng first set up the incubator, humidifier and other culture equipment, and then started the operation.

Mycelium needs to be cultured with agar, and Ye Feng carefully blew the mother bacteria sample on the agar.

Then give the culture medium proper ventilation to ensure the concentration of carbon dioxide.

It's done!

Transplanting is possible within half a month

"It's very simple, there shouldn't be any problem!"

Ye Feng said proudly after he finished.

Five incubators each cultured multiple bacterial colonies.

The mycelium growth density was controlled at one plant per square centimeter.

This variety of black truffle weighed half a pound each, and eight thousand plants were transplanted per acre of land, with a 0% survival rate, four thousand plants.

The mycelium produced by secondary splitting was not good, far inferior to the original sample mother fungus, and the degeneration speed was very fast.

However, the system can provide unlimited mother fungus samples, so as long as a large number of second-generation mycelium were derived, it could be supplied to the greenhouse. This is a complete technical monopoly.

"One incubator is one acre of land, and five of them can grow five acres, the area of a greenhouse."

After finishing the mycelium incubator, we have to consider the matching and problems in the greenhouse. The first is the mushroom bag, which is filled with a lot of sawdust and inoculated with mycelium for mycelium growth.

This thing is easy to make, just chop some wood, make sawdust and put it in the bag, but you have to add some nutrients.

Ye Feng hummed a song and went upstairs to let Alexander and others chop some trees back.

Alexander and Uncle Petrov were very curious:

"Boss, what trees do you want to cut? How big trees do you want to cut? How many trees do you need to cut? Why do you want to cut trees?"

The local people in Siberia have a natural resistance to logging, thinking that it will damage the environment.

But they still cut down the trees that need to be cut.

Ye Feng calmly replied:

"Just chop down the dead and decayed trees, pine wood, no matter how big or small, chop down as many as you can and bring them back for backup, if not enough, buy more from outside."

No big deal, what's a few trees?

And they can be reused anyway!

Truffles absorb carbohydrates from wood, and their ability to wood is average, so they can be used for a very long time.

And even if the mushroom bags cannot provide nutrients, they can be used as organic fertilizer for other vegetables, and the effect is very good.

The two Rakshasa men went to chop trees obediently, and they chopped down dozens of dead trees at the edge of the forest and pulled them back to the warehouse with a forklift.

They also have to find workers to split them up and get sawdust and bag them.

But it's still early, so there's no rush. You can start after the greenhouse is completely completed.

Ye Feng finished the laboratory again, and finally had time to take a look at his unmanned salvage submersible and metal detector.

These two things will come in handy tomorrow as a cover for his gold reward!

After breakfast the next day, Ye Feng deliberately gathered everyone to test the metal detector he bought on the farm. Detectors, and unmanned salvage submersibles.

He always talked about treasure hunting in the past, but he didn't expect that he actually bought treasure hunting toys this time. He was very curious.

Petrov, Alexander, Irina, and Chris were responsible for operating the unmanned salvage submersible, and Alexander happened to know how to use it.

Ye Feng and Vera played with metal detectors together!

The principle of metal detectors is very simple. It uses electromagnetic induction or radiation detection to detect metals and foreign objects.

It has the same structure as a mine detector!

Moreover, the new metal detector that Ye Feng bought can also distinguish between foreign objects, non-ferrous metals, and ordinary metals.

Non-ferrous metals have a higher frequency of alarm sounds. The louder the alarm sound, the larger the volume.

They detected the land by the lake inch by inch. As soon as it sounded, he dug in. There were really a lot of things.

But they were all sundries.

Coins, knives, iron sheets, waste nails

Until Ye Feng's detector suddenly found a harsh beeping sound.

Such a sharp and piercing alarm scared Vera, but it was obviously a large piece of non-ferrous metal.

Alexander and others also glanced at it curiously.

What is that? It actually made such a sound?

But they didn't think it was anything good, they just thought it was some scrap copper, underground water pipes and the like.

They didn't know what facilities there were here before.

If there is any treasure here, Ye Feng's luck is too incredible!

Under the rocks along the coast? How is it possible?

But Uncle Petrov was shocked. Others didn't know, but he knew.

He went with his boss to sell stolen goods last time, and he knew very well that the gold came from the farm and was dug out from the ground.

He quickly ran over to help dig for treasure, and while digging, he whispered to Ye Feng:

"Boss, isn't that what's going on down there?"

Ye Feng knew what was going on, but he still answered:

"We don't know yet, let's dig it out and see, maybe it's true!"

Of course he knew what was inside and knew the exact location long ago. He was just performing in front of these employees.

The two of them took shovels and dug half a meter. They heard two dull"bangs". They dug it up!

Ye Feng slightly dug away the stones and took a look!

It was indeed good!

The only difference from the last time was that this time the gold was in a box that had not decayed yet.

Because it was in the rocky beach and not in the water, the wooden box was relatively intact.

Petrov, Vera, Alexander, Irina, and Chris all gathered around the treasure chest and watched the boss dig it out himself.

Soon, most of the box was dug out!

Alexander pulled it out of the ground with force and found that there was another box underneath!

"Boss, do you want to open it and take a look first?"

"Take it back and have a look. There are other people in the farm in broad daylight."

Don't show your wealth to others. Although Ye Feng is not afraid, it will be troublesome to attract attention.

Petrov nodded and supported seriously:

"That's right, it must be kept secret. The boss and I have seen the things in here. It's not the first time we have found them!"

Everyone was very excited, and they kept muttering in their hearts, could this be the legendary golden treasure?

Vera and Chris were the most uneasy, and the expressions on their faces felt like they were watching an adventure movie.

The Petrov couple were also very happy and excited.
